l3〇〇ll5 玖、發明說明： t發明所屬技術領域3 發明領域 本發明涉及根據外部狀況執行相應的操作的安全閥 5 (國際專利分類F16K 17/36)中使用電動機作為操作裝置的 安全閥（國際專利分類F16K 31/04)，具體地說是涉及在用於 防止煤氣事故的燃氣斷路裝置中用作斷路機的斷路閥，更 具體地說，涉及一種使閥體相對於設在流路中的閥座發生 前、後移動進行流路的斷路/復原操作且動力源使用電機的 lG斷路閥。 t先前技術3 赘明背景 為了防止發生燃氣事故，長期以來採用過各種各樣的 女全裝置。其中有一種燃氣表稱為微電腦表，它由電池電 藏驅動，裝有微電腦，且内部設有燃氣斷路裝置。這種表 中的微電腦通過内置在燃氣表中的流量感測器監視燃氣流 里’並且還監視地震感測菇、燃氣壓力感測器、燃氣擎報 器 '一氧化碳感測器等感測器的狀況。當微電腦判定燃氣 的使用狀態出現異常時或者通過感測器感知到危險狀態 20時，即通過設在燃氣表内部的斷路閥將燃氣切斷。這種微 電腦表由於安全性很高，燃氣配管也很容易進行，且價格 低廉荨原因得到了很大的普及。以日本為例，幾乎所有的 家庭中都安裝了這種燃氣表。 另外’將流量感測器计測到的燃氣流量資訊利用電話 5 1300115 ^等進打集中監視/計量，具有所謂的“遠程計量功能，，的集 中監視型微電腦燃氣表的市場份額也在不斷增加。同時， 對其作為—师轉端的使时便性方面的絲也在不斷 5 10 15 對於這樣的集中監視型微電腦表等燃氣表，也要求能 夠通過簡單的電子開_作或者通過電話線等進行的遙控 操作就可以進行燃氣的切斷/復原，通過裝在微電腦表中的 電池的電能就可以切斷和恢復燃氣，並且在保持開閱狀能 和閉閥狀態時無需消耗能量。 心 其㈣斷路閥的主流驅動方式以前一直使用電磁螺線 官，但是近年來，以能夠實現比較強的關閉力和恢復力且 在不通電時也能料住狀態的PM型步進電機作為驅動源 的斷路閥倍受注目。制是轉子設在燃氣流路内、定子执 在燃氣流路外，具有氣密隔斷壁的斷路閥由於具有在燃氣 流路上容易安裝的特點，是一種很有前途的產品。 下面先描述一下現有的這種斷路閥的結構。 這種以PM型步進電機為驅動源的現有斷路閥是眾所 周知的（具體可參照日本專利公開公報特開平u_2351號第 4-5頁及第1圖，特開平9-210237號公報第3-5頁以及第4圖）。 2 0 曰本專利公開公報特開平11 - 2 3 51號公報前述的斷路 閥如第5圖中所示，設有構成氣密隔斷壁的帶有凸緣的杯狀 殼體6，該殼體6通過鋁擠壓等方式成形，其外圍裝有定子 4。前述殼體6的開口部上嵌著由聚酸樹脂等具有自我潤滑 性的合成樹脂製成的徑向滑動軸承外襯套3，與該外概套3 1300115 設成一個整體的凸柱5被設置在偏心位置並向前方突出。殼 體6内插裝有由聚醛樹脂等具有自我潤滑性的合成樹脂製 成的徑向滑動軸承内襯套12，引導螺杆17支承在前述外襯 套3及前述内襯套12中，且其前端的凸螺紋部17a從外襯套3 5中伸出，可以在正、反方向上自由旋轉。引導螺杆17上與 前述定子4相對應的位置上安裝有轉子16，在設置在轉子16 和前述外觀套3之間的2塊塾板20、21之間夾入有第1轴向負 荷用滚珠軸承18，該軸承18通過在圓周上設置3粒以上的滾 珠19而構成。轉子16和前述内襯套12之間也夾入了具有同 10樣構成的第2軸向負荷用滾珠軸承24，第2軸向負荷用滾珠 軸承2 4和内襯套12之間還設有彈簧墊圈狀的彈性伸縮部件 30。閥體25由閥片27、和與前述凸柱5進行凸杈_凹孔配合 且與凸螺紋部分17a進行螺紋螺杆配合的閥片支承部件“所 構成。 15 另外，外襯套3的外圍套有帶有階梯的圓盤狀凸緣2， 同時，殼體6的外周還嵌合有供定子4焊接在其上的圓環狀 平板凸緣7。上述階梯狀凸緣2及平板凸緣7相互固定在一 起，並將外襯套3的凸緣和殼體6的凸緣同時夹入其中。並 且，在階梯狀凸緣2和平板凸緣7之間以前後方向被壓緊的 2〇狀態安裝有由彈性合成樹脂製成的剖面圓形的彈性贫封呷 件8 〇 以下彳田述具有上述構成的斷路閥中的操作情、兄 在燃氣的使用狀態出現異常等情況時，轉子Μ中會在 圖中未示出的控制部的控制下通電，發生正轉，使引導螺 1300115 杆17也發生正向旋轉，閥體25從引導螺杆17—側向閥座28 一側前進，頂住閥座28，關閉流路，將流體切斷。另外， 在進行復原操作時，在前述控制部的通電控制下，引導螺 杆17發生反向旋轉，使閥體25從閥座26 —側向引導螺杆17 5 一側後退，使流路打開，重新開始供應流體。 這種斷路閥在設置在流路中時，燃氣等的流體壓力將 對其施加上朝向閉閥方向的推力，因此在開閥的瞬間需要 比其他時間更強的推量，在與軸向垂直的方向上加到轉子 16和外襯套3上的力量也會變大◦但是，第1軸向負荷用滾 10 珠軸承18能移承受該負荷，由摩擦力產生的轉矩損失能夠 減輕。 另一篇先有技術文獻特開平9-2102 3 7號公報中前述的 斷路閥如第6圖中所示。這種斷路閥的構成與第5圖中的斷 路閥幾乎相同，其不同點在於：沒有設置徑向滑動軸承的 15 内襯套和外襯套；且設置在轉子42的引導螺杆50上的滾珠 軸承44、45是一般常用的徑向滾珠軸承，並由焊接在定子 41的兩端的金屬板即凸緣46、後蓋47進行定位；氣密隔斷 壁不是杯狀的殼體而是兩端開口的管體43，管體43的兩端 和凸緣46、後蓋47之間設置密封部件48、49 ;凸柱53為頭 20 部經過加工的金屬棒，且被***（固定）到凸緣46中。 滾珠軸承44、45能移承受軸向負荷，從而可以減輕開 閥等時等的摩擦力引起的轉矩損失。 這種斷路閥的操作與第5圖中的斷路閥相同，故在此省 略對其的說明。 1300115 這種以PM型步進電機為驅動源的斷路閱操作性能穩 定，電源功較小，因此需要保持轉子的轴心以及確保與氣 密隔斷壁的同軸度。 另外，-般來說燃氣表被設置在戶外，暴露在從夏日 5的直射陽光下超過50°c的溫度到嚴冬期低於_2(rc的溫度 的嚴酷環境中，同時位於流路一側的部件則是在低分子2 化氫燃料氣體以及燃氣中所含的微量水分、硫化氫、二2 化硫等的精製過程中的雜質(活性氣體)等的有機:環 經受上述的嚴酷溫度變化。另外，大氣一側是接近於屋外 H)的飽和濕度的高溫高濕環境，而在燃氣表内部則是可能發 生結露等的嚴酷條件。另外，在燃氣表的❹顚（一般為 10年)内，還要求具有無燃氣浪漏等極高的氣密可靠性。 換句話說，既要實現轉子軸心、的保持精度，又要實現 極高的氣密可靠性。 15 但是’在第5圖中所示的現有斷路閥中，旋轉軸（引導 螺杆）17的徑向定位通過合成樹脂製成的徑向滑動轴承亦 即外襯套3和内襯套12來進行，由於合成樹脂與金屬引導螺 杆Π之間的線性膨脹係數差很大，需要將孔徑設置得大一 2些，以免低溫時使引導螺杆17被抱死。然而這樣一來，外 20概套3、内概套I2和引導螺杆n的徑向誤差必將增大，而且 聚駿樹脂等具有自我潤滑性的合成樹脂在成形時的收縮率 很南’成型時的尺寸精度很難提高，從而存在旋轉軸即引 導螺杆17的軸心保持精度很低的間題。 同日守，第5圖中的斷路閥中的徑向滑動軸承即外襯套 1300115 3、内襯套12是合成樹脂製成的，故比較容易發生磨損。磨 損產生的粉末上還容易附上靜電，特別是滾珠19與外襯套 3、轉子16的凹狀内腔面接觸時產生的磨損粉末會混入墊板 20、21和滾珠19之間，附著在滾珠19的外表面上，阻礙滾 5珠19的順暢旋轉，引發第1軸向負荷用滾珠軸承18、第2軸 向負荷用滾珠軸承24功能下降、工作不穩定的間題。 另外，在第6圖中所示的現有斷路閥中，轉子16的軸心 保持由於是由金屬板凸緣46、後蓋47及徑向滾珠軸承44、 45來進行，故與引導軸17之間不存在線性膨脹係數差，可 ίο以減小徑向公差。但是，軸心的決定一邊使凸緣46、轉子 41、後蓋47和其他多個的部件定位一邊進行的焊接過程的 精度所決定的，這一焊接步驟同時也是使管體43、凸緣46、 後盍47保持氣密的步驟，故在製造過程中需要非常仔細， 從而存在著造價偏高的問題。 15 同時，需要密封的位置為密封部件48、49這二處地方， 故存在著氣密可靠性不高的問題。 另外，在第6圖的斷路閥中，凸緣46和定子41的焊接部 位54位於流路一側的表面處於燃氣環境中，另一表面處於 空氣環境中，因此將同時暴露在作為燃料的燃氣、燃氣中 20所含的微量水分、硫化氫、二氧化硫等的精製過程中的雜 質（活性氣體）等溫度有變化的有機物環境以及接近於戶外 的飽和濕度的高溫高濕環境中，且燃氣表内部也是可能發 生結露等的嚴酷條件。一般來說，經過焊接的金屬結構之 間會殘存有畸變，容易發生晶粒界面腐蝕及應力腐蝕，存 1300115 在破衣、損㈣危險性。—旦焊接雜Μ損壞的話合 產生燃氧洩漏的問題。 “ 【發明内容】 發明概要 -另外，第6圖的斷路閥中的軸承44、45採用的 徑向滾珠軸承，存在著整體造價變高的問題。n貝、 5 曰本1明旨在解決先有技術中的上述問題，其目的在於 提供讀-種斷路閥，它可以提高能夠忍财長期使用過程 中=濕度應力、溫度應力、化學物質的應力等應力的氣密 10可罪=和轉子的軸心保持精度，只用很小的電源功率就能

這樣，轉子的軸心由金屬隔斷壁和徑向/轴向共用滾珠 軸承進行支承，線性膨脹係數將與金屬性的旋 5同，因溫度變化引發的鎖死等現象的發生可能性將會降 低’徑向間隙可以設定成最低的限度，隔斷壁底面側一側 的轉子轴心精度可以提高，從而通過很小的電源功耗實現 穩定的操作性能。 另外，通過在轉子和蓋體之間、或者在轉子和隔斷# _ 八 '又置了控向/軸向共用滾珠軸承，消除了滑動接觸部

Further, the outer casing 3 is sheathed with a stepped disc-shaped flange 2, and the outer periphery of the casing 6 is fitted with an annular flat plate flange 7 to which the stator 4 is welded. The stepped flange 2 and the flat plate flange 7 are fixed to each other, and the flange of the outer bushing 3 and the flange of the casing 6 are simultaneously sandwiched therein. Further, in a state of being pressed between the stepped flange 2 and the flat plate flange 7 in the front-rear direction, a circularly-shaped elastically-depleted element 8 made of an elastic synthetic resin is attached. In the case of the operation of the shut-off valve configured as described above and the occurrence of an abnormality in the use state of the gas, the rotor is energized under the control of a control unit (not shown), and a forward rotation occurs to cause the guide screw 1300115. The forward rotation also occurs, and the valve body 25 advances from the side of the guide screw 17 to the side of the valve seat 28, against the valve seat 28, closes the flow path, and cuts off the fluid. Further, when the restoration operation is performed, the guide screw 17 is reversely rotated by the energization control of the control unit, and the valve body 25 is retracted from the side of the valve seat 26 toward the guide screw 17 5 to open the flow path. Start supplying fluid. When such a shut-off valve is disposed in the flow path, the fluid pressure of the gas or the like will exert a thrust toward the valve closing direction, so that a stronger thrust than other times is required at the moment of opening the valve, and is perpendicular to the axial direction. The force applied to the rotor 16 and the outer bushing 3 in the direction is also increased. However, the first axial load roller 10 ball bearing 18 can be moved to withstand the load, and the torque loss due to the frictional force can be reduced. The above-mentioned disconnecting valve in the above-mentioned Japanese Patent Laid-Open Publication No. Hei 9-2102 No. 3-7 is shown in Fig. 6. The configuration of such a shut-off valve is almost the same as that of the shut-off valve of Fig. 5, except that the inner bushing and the outer bushing are not provided with the radial sliding bearing; and the balls provided on the guiding screw 50 of the rotor 42 are provided. The bearings 44, 45 are generally used radial ball bearings, and are positioned by a metal plate welded to both ends of the stator 41, that is, a flange 46 and a rear cover 47; the airtight partition wall is not a cup-shaped casing but is open at both ends. The pipe body 43, the two ends of the pipe body 43 and the flange 46 and the rear cover 47 are provided with sealing members 48, 49; the boss 53 is a processed metal rod of the head 20, and is inserted (fixed) to the flange. 46. The ball bearings 44 and 45 can be moved to receive an axial load, so that the torque loss caused by the frictional force such as the valve opening or the like can be reduced. The operation of this circuit breaker is the same as that of the circuit breaker in Fig. 5, so the description thereof will be omitted here. 1300115 This PM-type stepping motor is used as the driving source for stable circuit-breaking operation and low power supply. Therefore, it is necessary to maintain the axis of the rotor and ensure coaxiality with the airtight partition wall. In addition, the gas meter is generally set outdoors, exposed to temperatures from 50 ° C in direct sunlight from summer 5 to harsh temperatures below _2 (rc temperature in the winter), while being located in the flow path The one-side member is an organic substance such as a low molecular 2 hydrogen fuel gas and a trace amount of moisture contained in the gas, hydrogen sulfide, sulfur dioxide, etc. (active gas), etc., the ring is subjected to the above-mentioned In addition, the atmosphere side is a high-temperature and high-humidity environment close to the saturation humidity of the outside H), and the inside of the gas meter is a severe condition in which condensation may occur. In addition, in the enthalpy of the gas meter (generally 10 years), it is required to have extremely high airtight reliability such as no gas leakage. In other words, it is necessary to achieve the maintenance accuracy of the rotor shaft and achieve extremely high airtight reliability. 15 However, in the conventional circuit breaker shown in Fig. 5, the radial positioning of the rotary shaft (guide screw) 17 is performed by the radial sliding bearings made of synthetic resin, that is, the outer bushing 3 and the inner bushing 12. Since the linear expansion coefficient difference between the synthetic resin and the metal guiding screw Π is large, it is necessary to set the aperture to be larger or larger to prevent the guiding screw 17 from being locked at a low temperature. However, in this case, the radial error of the outer 20 set 3, the inner set I2 and the lead screw n must be increased, and the shrinkage of the self-lubricating synthetic resin such as Jujun resin is very south. The dimensional accuracy of the time is difficult to increase, and there is a problem that the rotation axis, that is, the axis of the lead screw 17 is kept at a low precision. On the same day, the radial sliding bearing in the circuit breaker in Fig. 5 is the outer bushing 1300115. 3. The inner bushing 12 is made of synthetic resin, so wear is more likely to occur. The powder generated by the abrasion is also easily attached with static electricity, and in particular, the abrasion powder generated when the balls 19 are in contact with the outer liner 3 of the outer liner 3 and the concave inner cavity surface of the rotor 16 is mixed between the backing plates 20, 21 and the balls 19, and is attached thereto. On the outer surface of the ball 19, the smooth rotation of the roller 5 bead 19 is inhibited, and the first axial load ball bearing 18 and the second axial load ball bearing 24 are lowered in function and the operation is unstable. Further, in the conventional circuit breaker shown in Fig. 6, the axial center of the rotor 16 is held by the metal plate flange 46, the rear cover 47, and the radial ball bearings 44, 45, so that the guide shaft 17 is There is no linear expansion coefficient difference between them, which can reduce the radial tolerance. However, the determination of the axial center is determined by the accuracy of the welding process performed while positioning the flange 46, the rotor 41, the rear cover 47, and other components, and this welding step is also to make the tubular body 43 and the flange 46 The rear crucible 47 is kept airtight, so it needs to be very careful in the manufacturing process, so that there is a problem of high cost. At the same time, the position where the seal is required is the two places of the sealing members 48, 49, so there is a problem that the airtight reliability is not high. Further, in the circuit breaker of Fig. 6, the flange 46 and the welded portion 54 of the stator 41 are located on the side of the flow path in a gas atmosphere, and the other surface is in an air environment, and thus will be simultaneously exposed as a fuel. An organic environment having a temperature such as a trace amount of moisture contained in 20 gas, gas, or sulfur dioxide, and an impurity (reactive gas) in a refining process, and a high-temperature and high-humidity environment close to outdoor saturated humidity, and Inside the gas meter is also a harsh condition in which condensation may occur. Generally, there is distortion between the welded metal structures, and grain boundary corrosion and stress corrosion are likely to occur, and the 1300115 is in danger of being damaged or damaged. If the welding noise is damaged, it will cause a problem of oxygen leakage. [Explanation] Summary of the Invention - In addition, the radial ball bearings used in the bearings 44 and 45 in the circuit breaker of Fig. 6 have a problem that the overall cost is high. n, 5, and 1 are intended to solve the problem. The above problems in the art, the purpose of which is to provide a read-type disconnecting valve, which can improve the airtightness of the stress of the humidity stress, the temperature stress, the stress of the chemical substance during long-term use, and the rotor. The shaft maintains accuracy and can achieve the same day with only a small power supply: stable operating performance and high operational durability, and high economical efficiency through simple construction. The problem is that, in the present invention, the metal 15 is coaxially disposed at the center of the open end of the steel-shaped metal partition wall of the hole, and the metal cover body is provided with a hole through which the aforementioned shaft passes, in the cover body and A radial/axial common ball bearing is coaxially disposed between the rotors to support the axis of the rotor while supporting the axial load of the cover body and the rotor. The metal partition wall, the metal cover body and the diameter are thus passed through. /Axial shared ball bearing supports the axis of the rotor. The linear expansion coefficient will be approximately the same as that of the metal rotating 0. The possibility of locking due to temperature change will be reduced, and the radial clearance can be set to the minimum. The limit of the rotor axis on the side of the open end of the partition wall can be improved, thereby achieving stable operation performance by a small power consumption. In addition, the present invention also partitions the wall of the 1300115 from the pot-shaped metal without the through hole. The bottom surface is coaxially provided with a radial/axial common ball bearing that supports the axis of the rotor while supporting the axial load of the partition wall and the rotor. Thus, the axis of the rotor is separated by a metal partition wall and a radial/shaft Supporting the common ball bearing, the linear expansion coefficient will be the same as the metallic rotation 5, and the possibility of locking due to temperature change will be reduced. 'The radial clearance can be set to the minimum limit, and the bottom side of the partition wall can be set. The rotor shaft accuracy on one side can be increased to achieve stable operation performance with a small power consumption. In addition, through the rotor and the cover Or in the rotor and partition # _ 八 ', and set the steering / axial shared ball bearing, eliminating the sliding contact knife: wear powder is not easy to occur, and even if the wear powder is produced, it is not easy to be charged due to metal powder The function of the ball bearing can not achieve low operation and can achieve high operational durability. - Then, since there is no through hole in the partition wall, a seal is used inside and outside the partition wall. It can reduce the airtight reliability of the faulty part. In addition, since the axis of the rotor is kept at the time of inserting the radial/axial common ball bearing, completing the assembly of the partition wall and the cover, Therefore, the stator and the flange can be fixed by using a lower precision machining method such as riveting, which can prevent the strength of the material from being lowered due to welding and the difficulty in manufacturing conditions, and will not cause combustion even if it is damaged. Gas leakage, resulting in high airtight reliability and economy. In addition, the radial/axial common ball 12 1300115 bearing can be formed by a simple structure such as a partition wall, a rotating shaft and a ball, or by a cover body, a rotating shaft and a ball, so that high economical efficiency can be achieved. Therefore, the short-circuit valve of the present invention can improve the airtight reliability of the stress such as the humidity stress, the temperature stress, the stress of the chemical substance during long-term use, and the axial center holding accuracy of the rotor, and only a small power supply is required.

The possibility will be lower, and the radial clearance can be set to a minimum. The rotor shaft accuracy on the open end side of the partition wall can be improved, and stable operation performance can be achieved with a small power consumption. At the same time 'by providing a radial/axial common ball bearing between the rotor and the cover, the sliding contact portion is eliminated, and the abrasion powder is less likely to occur, and the 13 1300115 N吏 produces a pure #末, because it is a metal _ this attached The function of the ball bearing does not depend on the durability of the operation.

the inner side of the stator is provided in the same sleeve, and the inside is made deep, and the coaxial two-section body has no through-hole. a steel-shaped metal H) plate partition wall; a rotor disposed on the inner side of the partition wall opposite to the stator; and a coaxial cylindrical front end provided on the rotor at a side of the partition wall side having a smaller diameter than other portions a thin shaft portion, and a metal rotating shaft having a groove having a smaller diameter than the other portions on the open end side of the partition wall; coaxially disposed on the open end of the partition wall, and having a center through which the rotary shaft 15 is inserted a hole coaxially disposed on the open end of the partition wall, and having a hole through which the rotating shaft can be inserted in the center, and a position opposite to the groove of the rotating shaft outside the center hole is provided with the central hole a cover made of a metal plate having a concave portion that is bulged outward from the inside of the partition wall; a steel portion of the (10) steel portion of the partition wall and the front end portion of the rotating shaft is provided with a plurality of gold which can be twisted freely a ball; a plurality of metal balls that are freely rotatable between the concave portion of the cover body and the groove of the rotating shaft; and an outer side of the rotor on the rotor side protruding from the groove of the rotating shaft in the direction of the groove to be coaxial with the rotating shaft The columnar shape Y can hold the ball when the aforementioned rotating shaft is set to be vertical, and a temporary fixing device that does not come into contact with the ball after the cover body is inserted; and 17 1300115 is provided to flow from the hole in the cover body a screw pushing mechanism on the aforementioned rotating shaft protruding from the road side; a sealing member that fixes the rotating shaft and is provided with a flange for allowing the stator to protrude therefrom; and a sealing member that seals the flange and the partition wall; An interposer on the auger mechanism; and a rotation preventing means for placing the fifth flange on the flange to restrict the rotation of the valve body. The k-like 'rotor shaft' is supported by a metal cover and a radial/axial common ball bearing, and the linear expansion coefficient and the metallic rotating shaft can be almost equal, and the possibility of locking due to temperature change occurs. It will become lower, the radial clearance can be reduced to a minimum, and the #孀10 sub-axis accuracy of the side of the partition wall can be improved, and stable operation performance can be achieved by reporting the power consumption of the power supply. By providing a radial/axial common ball bearing between the rotor and the cover or between the rotor and the partition wall 2, the sliding contact portion 5 is eliminated, and the abrasion powder is less likely to occur, and even if a wear powder is generated, It is a metal powder, so it is not easy to be charged, and the function of the ball bearing is not reduced, so that high operational durability can be achieved. Moreover, since there is no through hole in the partition wall, a Φ dense part is used inside and outside the partition wall. It is possible to carry out the sealing possibility, so that the faulty portion can be reduced to achieve high airtight reliability. 0 The invention in claim 9 is the aforementioned in the technical solution 8.

Thus, the assembly efficiency can be improved and the height can be realized. In addition, since the axial center of the rotor is kept in the inserted radial/axial common ball bearing, the time when the partition wall and the cover body are assembled is completed, and the fixing of the stator 5 and the flange can be compared by precision such as riveting. The low processing method can prevent the material strength from being lowered due to welding and the difficulty of manufacturing conditions, and if it is damaged, it will not cause gas leakage, so that high airtight reliability and economy can be achieved. 10 15 20 Then, the rotation limiting device is placed on the flange in a non-movable manner, and the stator is also fixed on the flange, and the screw pusher is arranged on the rotating shaft of the rotor. When the structure rotates relative to the stator, the valve body that is restricted to the stator will move linearly in the front-rear direction. Thus, the rotation direction of the assembly of the rotor, the partition wall and the cover body is not necessary. : The assembly process does not require positioning operation, and can improve the group's ΐ 率 rate' to achieve high economic efficiency. It is a simple structure bead bearing that passes through the partition wall, the rotating shaft and the ball, or the cover shaft and the ball. The current 彳/1 shared roll J is very economical.

From the economical point of view, it is preferable to use a part made of a previously plated steel plate such as a galvanized steel sheet. In the present embodiment, the ruthenium-plated steel sheet used is subjected to press working to the finished part. The comb-shaped magnetic poles of the first electromagnetic yoke iron 62 and the second electromagnetic yoke iron 63 are engaged by a predetermined gap. Specifically, the comb teeth of the two components are arranged such that the comb teeth in one assembly In the direction of rotation is roughly in the middle of the two comb teeth on the other component. A partition wall 66 made of an austenitic steel-based stainless steel plate is disposed on the inner side of a die 65. The partition wall 66 is provided with a cylindrical portion along the magnetic pole, and one end forms a closed portion, a crucible P66b, and an inner pin concentric with the bottom portion 66b. The shape 6 is. In other words, the partitioning Ying 66 is processed by a stepwise incremental forming method of two coaxial non-through-hole pots. 3 The material of the soil 66 can be selected from non-magnetic stainless steel plate, copper alloy, and 5 gold. Considering that gas is a low-molecular hydrocarbon hydrogen used as a fuel, 15 and a small amount of water and hydrogen sulfide contained in the gas. In the organic environment such as impurities (active gas) in the fine coat of sulphuric acid, such as diacidified sulphur, it is not subject to deterioration due to the aforementioned severe temperature change, but also maintains stable performance and chemical corrosion, and also can be processed by continuous pressing. Since it is formed and has a thin thickness processability capable of achieving high economic efficiency, it is most suitable to form austenitic steel type steel steel sheet by stepwise forming. In the case where the airtight reliability is the most preferable condition, it is preferable to carry out a solution heat treatment after the stepwise forming process to eliminate the __ stress and the grain refinement. The rotor 71 is made of a permanent magnet 22 1300115 stone 67 which is circularly tubular and whose outer circumference is subjected to polarization magnetization, a rotating shaft 69 which is provided to penetrate the permanent magnet 67 and is provided with a lead screw 68 at one end, and is used for the permanent magnet 67 and The support member 70 to which the rotating shaft 69 is fixed is constituted, and the outer peripheral portion of the permanent magnet 67 and the magnetic poles of the electromagnetic yokes 62, 63 of the stator 65 are disposed opposite to each other on the inner side of the partition wall %5. Since the inner side of the partition wall 66 will become the gas side, it is required that the material constituting the rotor 71 has a high resistance to the surname. Therefore, the permanent magnet 67 is preferably made of a ferrite-cored magnet having high corrosion resistance, and the rotating shaft 69 may be made of nickel or chrome-plated brass and stainless steel. However, it is preferable to use a stainless steel steel bar in consideration of a corrosive gas such as hydrogen sulfide which may be contained in the gas. As for the support member 70, it is preferable to use a crystalline synthetic resin having high oil resistance such as polybutylene terephthalate (PBT) resin for the purpose of the performance of the hydrocarbon-resistant compound. At the open end 66d of the partition wall 66, a cover 72 is provided. The cover body 72 15 has substantially the same outer diameter as the open end 66d, has a hole 72a through which the rotary shaft 69 can pass, and has a recess 72b coaxial with the hole 72a and bulging from the inside of the partition wall 66. The cover body 72 is formed of a stainless steel plate by a stepwise forming process, pressed into and disposed on the open end 66d, so that the rotor is wrapped inside the partition wall 66, and the lead screw 68 is extended from the hole 72a. 20 Since the cover 72 is also on the side of the gas flow path, it is also required to have a saturable rice resistance. Nickel or chrome plated brass or stainless steel may be used. However, considering that the gas contains a small amount of a residual gas such as hydrogen sulfide, it is preferably made of stainless steel, and can also be formed by a continuous step forming process by a stepwise forming process, which can achieve a high economy. Sex. 23 1300115 In addition, 'the cover body is necessary—it is necessary to use non-magnetic, ie, when the micro-crack is generated due to the amount of stress, the other 5 plates are not leaking, and the secret dumping treatment is not necessary, and the unique column f can be selected.

The inner diameter D3 of the recess 72b on 72 is set to be slightly larger than the sum of the outer diameter D2 of the groove 69b and the outer diameter D0 of the ball 75. Further, the number of the balls 73 and the balls 75 is smaller than the average diameter of the inner pot portion 66e, the inner diameter D3 of the recess portion 72b, and the average diameter of the front end thin shaft portion 69a and the outer diameter D2 of the groove 69b, respectively, by the ball 73, The result of the diameter D0 of the ball 75 is large, so that the bearing 74 and the bearing 76 can support the radial position of the rotary shaft 69. 24 1300115 In addition, in the present embodiment, when the pitch holder is provided in the ball 73 or the ball 75, the number of the balls 73 and the balls 75 is three or more, even if it is smaller than the inner pot portion 66c, The inner diameter of the recessed portion 72b, the average diameter of the outer diameter of the front end thin shaft portion 69a and the groove 69b, and the number 5 obtained by dividing the diameter of the ball 73 and the ball are also not problematic. An arc ri for coupling the difference between the front end thin shaft portion 69a (outer diameter D2) of the rotating shaft 69 and the other portion (outer diameter D1), and the groove 69b (outer diameter D2) and the large diameter of the support member 70 side The arc of the difference between the portions (the outer diameter D1) is preferably set to be approximately 2 to 2 106% of the ball 73 and the radius D0 of the ball 75, respectively. However, from the viewpoint of the economical efficiency of the machining accuracy of the rotary shaft 69, it is not necessary to set such a restriction. In addition, in the above description, the axial/radial shared ball bearings 74, 76! The main dimensions of 4 are set to be the same, but it is not necessary to impose such restrictions. 15 This kind of shut-off valve does not perform any operation under normal conditions, but is only placed on the side, but at the end of the life, if the open circuit signal appears for the first time, the necessary operation is also required, and the use is not deteriorated. The lubricating oil that is condensed is used in a state where it is not oiled. Therefore, the material of the ball 73 and the ball 75 is preferably used in austenitic steel such as SUS304 which is rich in oil and oil. Stainless steel ball. Is the support member provided between the groove 69b on the rotary shaft 69 and the support member 7? 70 forms a temporary fastening device 77. The temporary fixing device 77 has a cylindrical shape coaxial with the rotating shaft 69, and protrudes in the direction of the outer side __; when the power shaft 69 is vertically disposed, the initial can be fixed, and after the cover 72 25 1300115 is inserted, The ball 75 does not come into contact. When the seal is fixedly secured in the opening in the wall 78 of the flow path, the rotary shaft 69 will protrude from the hole. As shown in Fig. 2, the centrally projecting portion 79a of the center hole is formed integrally with the flange 79. The electromagnetic field iron Q in the stator & is fixed to the outside of the flow path tube wall 78 by means of fastening or the like, and a "made of synthetic rubber" is disposed between the flange and the outer wall of the open end 66d of the partition wall 66. The sealing member 80, such as a ring, is sealed in an airtight state inside and outside the flow path tube wall 78. The wide body 84 is composed of a valve piece supporting member 82 and a wide sheet 83, and the intermediate piece supporting member 82 is composed of self-lubricating synthetic Made of resin, the guide nut 81 formed on the center hole 10 thereof is threadedly fitted with the guide screw 68 on the side of the flow tube wall 78 in the rotary shaft 69. The valve piece is slidably disposed on the valve piece supporting member 82, Made of a flexible material such as synthetic rubber. As shown in Fig. 2, the side of the flange 79 of the valve piece supporting member 82 is provided parallel to the axial direction and can be engaged with the projection 79a on the flange 79. The slit 82a, the slit 82a and the projection 79& constitute a rotation preventing device, and the guiding screw 68 and the guiding nut 81 constitute a screw pushing mechanism, and the auger mechanism and the rotation preventing device constitute a linear motion mechanism. The blade supporting member without the guiding nut 81 82 materials can A synthetic resin having a solid 20 lubricating material such as 1 oxymethyl, polytetrafluoroethylene, graphite crucible lid or indium disulfide is used. The valve body 84 and the flange 79 are provided with a compressed, thus valve The body 84 applies a spring 85 that is resilient to the direction of the valve seat 86, while the spring force of the spring applies an upward pressure to the radial/axial common ball bearing 76 in addition to the valve closing, thereby improving the alignment accuracy of the shaft center. 26 1300115 When assembling the circuit breaker, as shown in Fig. 3(a), the center shaft is kept vertical, the open end 66d of the partition wall 66 is directed upward, and a plurality of metal balls are mounted inside the partition wall%. 73; Then, the rotor 71 is attached to the inner side of the partition wall 66, and a plurality of metal balls 75 are placed on the temporary fixing device 77. 5 At this time, the ball 75 does not come into contact with the groove 69b, and the outer diameter D5 is the sum of the diameter D2 of the groove 69b and the diameter of the ball 75 twice, and is larger than the inner diameter D3 of the recess 72b of the lid 72. Next, as shown in Fig. 3(b), the lid body 72 is pressed into the open end 66d of the partition wall 66 and pressed therein. φ 10 At this time, the ball 75 will be pressed by the concave portion 72b, and the outer circumferential diameter thereof will become the same as the inner diameter D3 of the concave portion 72b, close to or in contact with the groove 69b, and after being detached from the temporary fixing device 77, the ball 75 No contact occurs with the temporary fixture 77. Thus, the stacking process in which the partition wall 66, the ball 73, the rotor 71, the balls 75, and the cover body 72 are sequentially loaded can be realized, the assembly processing efficiency can be improved, and the economy can be improved. The operation and effect in the circuit breaker of Embodiment 1 will be described below. The use status of Ludang gas is not abnormal. When the signals from various sensors do not indicate dangerous information, the control unit from the microcomputer gas meter (not shown in figure 20) will not send current, and the rotor 71 is braking. The valve body 84 maintains a valve-opening state separated from the valve seat 86 by the action of the torque, and the gas can be circulated. At this time, the relative positional relationship between the rotor 71 and the partition wall 66 is as shown in FIG. 4(a). Since the spring 18 exerts a force on the valve body 84 toward the valve seat 86, the force is 27 1300115 5 10 , so the valve The body 84 is biased toward the valve seat % side in the diagram of the axial clearance, that is, the left side in the fourth (4) diagram, and as a result, the radial/axial common ball bearing % will be subjected to the axial load, and at the same time, due to the elastic force exerted by the spring 85 By the action of the pressurization, the axial center holding accuracy of the radial/axial common ball bearing 76 can be improved.

At this time, the relative positional relationship between the rotor 71 and the partition wall 66 is as shown in the fourth (b) diagram. "Because the valve is secreted and is pressed by the linear motion mechanism 20, the valve body 84 is axially The inside of the gap pattern will be offset from the inner pot portion 66e-side of the partition wall, that is, the right direction in the fourth (4) diagram. As a result, the pressure Ifg of the valve piece 83 is elastically applied to the backward/axial common-bead bearing 74 as both axial and pressurizing, so that the axial/axial shared ball bearing 74 is axially aligned. The quasi-precision can also be improved. 28 1300115 When the control unit of the microcomputer table judges that the danger has been removed from the signals from various sensors, it can be resumed in the case of ventilation, or the gas is used to operate on the watch or remote control disk after the dangerous situation is eliminated. When the recovery switch is used, or when a gas company or the like remotely transmits a 5 original command by communication means, a pulse current having a phase difference is applied to each of the wires of the exciting coil 61 to reverse the rotor 71. Rotation (the rotation in the counterclockwise direction from the valve body 84 side in the figure). Thus, under the pulling of the guiding screw 68, the valve body 84 will move toward the flange side, and will be disengaged from the valve seat to open the circuit breaker. After _, the valve body 84 will continue to move toward the side of the flange 79 until the valve plate is supported. The jaws 82 are placed over the cover 72 and the excess pulses are misaligned so that the circuit breakers are fully open. After that, even if the control unit of the microcomputer table stops supplying power, the rotor 71 will remain stationary under the action of the braking torque, and the disconnect valve will remain open. 5 When the return valve opening operation is performed, the relative positional relationship between the rotor 71 and the partition wall 66 is also as shown in Fig. 4(a), that is, the spring force of the valve body 84 is not pushed toward the valve seat 86-side. That is, in the schematic diagram of the axial gap, the lateral valve seat #86-side is the left side in the fourth (a) diagram. As a result, the radial/axial common thrust of the ball shaft 76 to the axial direction is at the same time, and since the spring force of the spring % also acts as a pressurizing force, the axial center of the radial/axial common ball bearing 76 can maintain accuracy. improve. Further, at the moment of opening the valve body 84 from the valve seat 86, the load generated by the fluid pressure of the gas or the like is superimposed on the elastic force of the spring cymbal, and the valve body 84 is prevented from moving in the valve opening direction, but Radial/vehicle common 29 1300115 Ball bearings 76 can withstand axial loads. Torque losses are seldom required to drive with very little power. In addition, in this circuit breaker using a PM type stepping motor as a driving source, in order to keep the operation performance stable and use a small power source, the axis of the rotor 5 is maintained and the coaxiality with the airtight partition wall is ensured. Degree is very important. In addition, the gas meter is generally set outdoors, exposed to a harsh environment from a temperature of more than 50 tons in direct sunlight in the summer to a temperature below a catching temperature in the winter, while the components on the side of the passage 78 are The low molecular weight carbonized nitrogen H) is subjected to the above-mentioned severe temperature change in an organic environment such as a fuel gas and a trace amount of moisture contained in the gas, a sulfurized gas, a sulfur dioxide, or the like during the purification process. In addition, the atmosphere side is a high-temperature and high-humidity environment close to the saturation humidity outside the house or a cool condition inside the gas meter. In addition, in the use of gas meters ("commonly called"), it is also required to have extremely high airtight reliability such as no gas leakage. That is, both the holding accuracy of the axis of the rotor 71 and the extremely high airtight reliability are required. Therefore, in the shut-off valve of Fig. 1, the inner pot portion 66c of the metal partition wall 66 is provided on the lid body 72 which is coaxially inserted into the anvil of the open end 6 of the partition wall 66. The concave portion 72b, the front end thin shaft portion 69a and the small diameter groove 69b formed in the metal rotating shaft 69 are disposed between the inner steel portion 66c and the front end thin portion 69a, and are mounted A metal ball 7 5 is formed between the concave melon and the groove 6 9 b to form a radial/axial ball bearing 74, 76 to hold the axis of the rotor 71. Thus, the linear expansion coefficient of the rotating shaft 69 and the support machine 30 1300115 is almost the same, the possibility of locking due to temperature change is low, and a minimum radial clearance can be set, so that the rotor 71 in Fig. 1 can be improved. The left and right axis accuracy allows stable operation with very little power. In addition, since there is no sliding contact 5 in the bearing, the abrasion powder is not easily generated. Further, even if the abrasion powder is generated, the phenomenon of the charge adsorption is less likely to occur due to the metal powder, and the function of the ball bearing is not easily lowered, so that high operation durability can be achieved. Therefore, the radial/axial common ball bearings 74, 76 can be constructed with a simple structure, achieving high economical efficiency. Further, since the partition wall 66 is not provided with a through hole, the inside and the outside of the partition wall 66 can be sealed by a sealing member 80, whereby the position of the fault can be reduced, and high airtight reliability can be realized. In addition, since the axial center of the rotor 71 is fixed to the insertion radial/axial common ball bearing 76, the assembly of the partition wall 66 and the cover body 72 is completed at 15 o'clock, so that the stator 65 and the flange 79 can be fixed. By using a low-precision machining method such as riveting, it is possible to prevent a decrease in material strength due to welding and difficulty in manufacturing conditions, and it is also possible to prevent gas leakage if it is damaged, thereby achieving high airtight reliability. Sex and economy. In addition, since the cover body 72 is made of a stainless steel plate by a stepwise forming method and a 20-step process, the partition wall 66 is formed by a step-by-step forming process of an austenitic steel-based stainless steel plate, so it belongs to a low molecular weight hydrogencarbon. In an organic environment such as miscellaneous or active gas such as miscellaneous water, hydrogen sulfide, and sulfur dioxide contained in fuel gas and gas, it can remain unchanged even if subjected to the aforementioned severe temperature changes, and can maintain stability. The performance, at the same time, 1300115 can also be formed by continuous stamping processing to achieve high economical. <In addition, since the outer side is provided to protrude in the direction of the groove 69b, the ball 75 can be fixed when the rotating shaft 69 (four) is in a vertical state, and the temporary fixing device 77 which does not contact after the ^72 (four) _5 can be used. The wood-based process improves assembly efficiency and achieves high economic efficiency. Knowing the above, the humidity*force in the use process of the present invention=force can be high in the long-term airtight reliability and the stress of the rotor, etc. 10 15 20 ::: Stable operating performance and very: the stability of the heart. The heart realizes the "in addition, in the above description, on the two sides of the rotor, the third picture, the fourth picture: the radial / axial shared ball shown Bearing 74: - It is also possible to set the radial/vehicle direction for the case where there is a problem with the axial load of the closed _ under the child = / axial total dowel bearing 74, and when the valve is opened for operation _ to the negative ' = problem The common ball bearing 2 has a plain bearing made of a synthetic resin having self-lubricating property, although 'the radial/axial directions 74, 76 shown in the drawing may be loaded into the multi-ball 73, 75." Full bead, type, = restrictive pattern, as long as it consists of more than 3 balls, like this: It is best to use a spacer for holding the axis. α Wide in the drawing 'Block wall 8 turns between 66 and flange 79 are radially compressed, and are set to be compressed at _ or 32 1300115 ~ ,; "Shao and all the guide member 82 and the female is tired - shaped body, but can also be separate members. In the case of a member which is not 5 =, it is preferable to provide a repulsion force between the support member a and the guide nut 81. In addition, although the middle piece 83 of the drawing is held by the reading piece supporting member _, it can also be used in the center (four) fitting (four) of the core to form a towel on the part of the piece 2, so that the center thief can penetrate the _, and reuse 10 Missing m Flying In addition, the linear motion mechanism has a truncated rod 68 and a guide nut 81, but a combination of a circular joint, a pot and a rack may be employed. 15 The technical effect of the tree is that, in the present invention, since the ball is passed through the = 盍 body and the radial / (4) ball, the core of the rotor is supported by the metal partitioning earth and the radial/axial co-shell bearing. It has almost the same linear expansion coefficient as the metal rotating shaft, and the possibility of locking due to temperature change is low, the radial clearance can be set to a minimum, and the axial accuracy of the rotor on the open end side of the partition wall can be improved. Therefore, the board is provided with a power supply valve with low power consumption and stable operation performance. 20 In addition, since the central axis can be vertical, the partition wall is held so that the opening is upward, and then a plurality of metal balls are inserted inside the partition wall, and the rotor is placed on the inner side of the partition soil, and the other plurality The metal ball is placed in the temporary solid-state wearing, and the cover body is inserted, and the eucalyptus assembly step fixed to the open end of the partition wall can improve the assembly processing efficiency, thereby providing an economical high-breaking valve. 33 1300115 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view showing a state in which an open circuit is in an open state according to a first embodiment of the present invention, and FIG. 2 is a broken view of the first embodiment of the present invention.
