Description

本発明は、微小開度表示機能付きバルブに関し、充水時に弁体を微小開度に制御する技術に係るものである。   The present invention relates to a valve with a minute opening indication function, and relates to a technique for controlling a valve body to a minute opening when water is filled.

従来、弁体の開度を表示する機能を有するバルブには、例えば特許文献１に記載するものがある。このバルブの減速機は、入力軸と出力軸（バルブの弁棒）の間に主動力伝達系を形成しており、主動力伝達系は適当な減速比をなす歯車列からなる。入力軸の周りには開度目盛を設けており、開度目盛を指示する開度指針が主動力伝達系における出力軸の回転に同期して回動する。   Conventionally, for example, Patent Document 1 discloses a valve having a function of displaying the opening degree of a valve body. This valve speed reducer forms a main power transmission system between an input shaft and an output shaft (valve valve stem), and the main power transmission system is composed of a gear train having an appropriate reduction ratio. An opening scale is provided around the input shaft, and an opening guide indicating the opening scale rotates in synchronization with the rotation of the output shaft in the main power transmission system.

バルブを開閉する際には、操作ハンドルによりキャップを介して入力軸を回転させ、入力軸に加えた回転力を、主動力伝達系を介して出力軸に伝えて、所定の減速比をもって出力軸を回転させ、バルブの弁体を所定の開度に開動（または閉動）させる。この際に、出力軸の回転に同期して開度指針が回動し、弁体の現在の開度を開度目盛において指し示す。   When opening and closing the valve, the operating handle rotates the input shaft through the cap, and the rotational force applied to the input shaft is transmitted to the output shaft through the main power transmission system. Is rotated to open (or close) the valve body of the valve to a predetermined opening. At this time, the opening degree pointer rotates in synchronization with the rotation of the output shaft, and the current opening degree of the valve body is indicated on the opening degree scale.

特開平９−３１７９３７JP-A-9-317937

ところで、管路を新設した場合や、既設管路のバルブを取り替えた場合には、管路の使用を開始する通水初期時に充水操作を行う必要がある。これはバルブの最初開栓時における急激な圧力変動に因って管路が破損することを防止するためであり、充水操作は、バルブの弁体を微小開度に制御してゆっくりと管路内に充水し、急激な圧力上昇を防止しつつ管路内を水で満たすものである。   By the way, when a pipeline is newly installed or when a valve of an existing pipeline is replaced, it is necessary to perform a water filling operation at the initial stage of water flow to start using the pipeline. This is to prevent the pipeline from being damaged due to sudden pressure fluctuations when the valve is first opened, and the water filling operation is performed slowly by controlling the valve body of the valve to a small opening. The water is filled in the road, and the inside of the pipe is filled with water while preventing a rapid pressure increase.

上記した従来の構成では、開度目盛が弁体の全閉位置から全開位置までの全開度範囲（９０度）を等分割して表示している。しかし、微小開度操作時に開度指針が回転移動する回転角度範囲は僅かなものであり、開度目盛における微小な回転角度範囲において開度指針の位置を視認して弁体の現在の開度位置を確認することは困難であった。   In the conventional configuration described above, the opening degree scale displays the entire opening range (90 degrees) from the fully closed position to the fully open position of the valve body by equally dividing. However, the rotation angle range in which the opening pointer rotates during a minute opening operation is very small, and the current opening of the valve element is confirmed by visually checking the position of the opening pointer in the minute rotation angle range on the opening scale. It was difficult to confirm the position.

本発明は上記した課題を解決するものであり、弁体の微小開度を容易に視認でき、弁体を微小開度位置に正確に制御することができる微小開度表示機能付きバルブを提供することを目的とする。   The present invention solves the above-described problems, and provides a valve with a minute opening indication function that can easily recognize the minute opening of the valve body and accurately control the valve body to the minute opening position. For the purpose.

上記課題を解決するために、本発明の微小開度表示機能付きバルブは、減速機により弁体の開閉操作を行うバルブであって、減速機は、入力軸部と、弁棒に接続された出力軸部と、入力軸部と出力軸部の間に所定の減速比を形成する歯車列と、弁体の開度を示す開度目盛部と、開度目盛部の開度目盛を指し示す開度指針部を備え、開度目盛部は、出力軸部の回転角度に対応する弁体開度を弁体の全開度範囲において表示する全開度表示目盛と、入力軸部の回転角度に対応する弁体開度を微小開度範囲において表示する微小開度表示目盛を有し、開度指針部は、出力軸部の回転に同期して全開度表示目盛において弁体の開度を指し示す全開度指針と、入力軸部の回転に同期して微小開度表示目盛において弁体の開度を指し示す微小開度指針を有することを特徴とする。   In order to solve the above problems, a valve with a minute opening indication function of the present invention is a valve that opens and closes a valve body by a speed reducer, and the speed reducer is connected to an input shaft portion and a valve stem. An output shaft, a gear train that forms a predetermined reduction ratio between the input shaft and the output shaft, an opening scale that indicates the opening of the valve element, and an opening that indicates the opening scale of the opening scale. The opening scale section corresponds to the rotation angle of the input shaft portion and the full opening indication scale for displaying the valve body opening amount corresponding to the rotation angle of the output shaft portion in the full opening range of the valve body. It has a minute opening indication scale that displays the opening of the valve body in the minute opening range, and the opening indicator portion indicates the opening degree of the valve body in the full opening indication scale in synchronization with the rotation of the output shaft portion. There is a pointer and a minute opening pointer that indicates the opening of the valve body on the minute opening display scale in synchronization with the rotation of the input shaft. And wherein the Rukoto.

本発明の微小開度表示機能付きバルブにおいて、開度目盛部は、弁体開度に対応する通水流量を全開度範囲において図形情報として視覚的に表示する流量表示目盛を有し、開度指針部は出力軸部の回転に同期して流量表示目盛において通水流量を指し示す流量指針を有することを特徴とする。   In the valve with a minute opening degree display function of the present invention, the opening degree scale unit has a flow rate display scale for visually displaying the water flow rate corresponding to the valve body opening degree as graphic information in the entire opening degree range. The pointer portion has a flow rate pointer indicating the water flow rate on the flow rate display scale in synchronization with the rotation of the output shaft portion.

以上のように本発明によれば、バルブを開閉する際には入力軸部を回転させることで所定の減速比をもって出力軸部が回転し、出力軸部の回転角度に対応してバルブの弁体が所定の開度に開動する。この際に、全開度指針が出力軸部の回転に同期して回動し、現在の弁体開度を全開度表示目盛において指し示す。一方、微小開度指針が入力軸部の回転に同期して回動し、弁体開度を微小開度表示目盛において指し示す。   As described above, according to the present invention, when opening and closing the valve, the output shaft rotates with a predetermined reduction ratio by rotating the input shaft, and the valve of the valve corresponds to the rotation angle of the output shaft. The body opens to a predetermined opening. At this time, the full opening degree pointer is rotated in synchronization with the rotation of the output shaft portion, and the current opening degree of the valve body is indicated on the full opening degree display scale. On the other hand, the minute opening pointer rotates in synchronization with the rotation of the input shaft portion, and the valve element opening is indicated on the minute opening display scale.

入力軸部の１回転は所定の減速比で出力軸部を所定回転角度に回転させる。換言すると、出力軸部の回転角度に対して入力軸部が減速比の逆数倍の回転角度に回転する。
したがって、全開度指針の回転角度が僅かである場合でも、微小開度指針が減速比の逆数倍の回転角度に回転することで、全開度指針が全開度表示目盛において指し示す僅かな弁体開度を、微小開度指針が微小開度表示目盛において拡大して大きな回転角度で表示することができるので、弁体の微小開度を容易に視認でき、弁体を微小開度位置に正確に制御することができる。 One rotation of the input shaft portion rotates the output shaft portion at a predetermined rotation angle with a predetermined reduction ratio. In other words, the input shaft portion rotates to a rotation angle that is a reciprocal number times the reduction ratio with respect to the rotation angle of the output shaft portion.
Therefore, even if the rotation angle of the full opening pointer is slight, the slight opening pointer rotates to a rotation angle that is the reciprocal of the reduction ratio, so that the slight opening of the valve indicated by the full opening indicator on the full opening indication scale is performed. Since the minute opening pointer can be enlarged and displayed at a large rotation angle on the minute opening indication scale, the minute opening of the valve body can be easily recognized and the valve body can be accurately positioned at the minute opening position. Can be controlled.

また、流量指針が流量表示目盛において弁体開度に対応する通水流量を図形情報として視覚的に指し示すので、操作者は一目で通水流量の多寡を理解することができる。   Moreover, since the flow rate pointer visually indicates the water flow rate corresponding to the valve opening as the graphic information on the flow rate display scale, the operator can understand the amount of the water flow rate at a glance.

以下、本発明の実施の形態を図面に基づいて説明する。図１〜図８において、微小開度表示機能付きバルブはバタフライ弁であり、弁箱１の内部に配置した弁体２を、弁棒３を回転駆動することで開閉操作する減速機４を備えている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 8, the valve with a minute opening indication function is a butterfly valve, and includes a speed reducer 4 that opens and closes a valve body 2 disposed inside a valve box 1 by rotating a valve rod 3. ing.

減速機４は、ケース５の上部開口側に入力軸キャリア６を回転自在に保持し、入力軸キャリア６が入力軸７を回転自在に保持しており、ケースの下部開口側に出力軸キャリア８を回転自在に保持している。   The speed reducer 4 rotatably holds the input shaft carrier 6 on the upper opening side of the case 5, the input shaft carrier 6 rotatably holds the input shaft 7, and the output shaft carrier 8 on the lower opening side of the case. Is held rotatably.

ケース５の上端面には入力軸キャリア６の周囲に沿って開度目盛部６１を配置している。開度目盛部６１は、全開度表示目盛６１１と流量表示目盛６１２とを入力軸７を隔てた対称の位置に配置してある。全開度表示目盛６１１は、弁体２の全閉位置から全開位置までの全開度範囲（０−９０度）を等分割して表示し、出力軸キャリア８の回転角度に対応する弁体開度を表示する。流量表示目盛６１２は、弁体２の全閉から全開までの開度変化に伴なって弁体開度に対応する通水流量を図形情報として視覚的に表すもので、入力軸キャリア６の周囲に帯状に延びる形状をなし、弁体開度が増すにつれて流量表示目盛６１２の帯幅が通水流量に応じて増加する。   An opening scale 61 is disposed on the upper end surface of the case 5 along the periphery of the input shaft carrier 6. The opening degree scale unit 61 has a full opening degree indication scale 611 and a flow rate indication scale 612 arranged at symmetrical positions with the input shaft 7 therebetween. The full opening indication scale 611 displays the full opening range (0-90 degrees) from the fully closed position to the fully open position of the valve body 2 in an equally divided manner, and the valve element opening corresponding to the rotation angle of the output shaft carrier 8. Is displayed. The flow rate display scale 612 visually represents the water flow rate corresponding to the valve element opening as graphic information as the opening of the valve element 2 changes from fully closed to fully open. The band width of the flow rate display scale 612 increases in accordance with the water flow rate as the valve element opening increases.

全開度表示目盛６１１および流量表示目盛６１２を囲んで回転角度目盛を兼ねる微小開度表示目盛６１３を設けている。微小開度表示目盛６１３は入力軸７の軸心回りの３６０度を等分割（例えば１６分割）した目盛で、入力軸７の回転角度（回転数）を１回転の１／１６ずつ示しており、入力軸７の回転角度に対応する弁体開度を表示するものである。本実施の形態では全開度表示目盛６１１、流量表示目盛６１２、微小開度表示目盛６１３は一枚の目盛盤６１４に配置している。   A minute opening degree display scale 613 that also surrounds the full opening degree display scale 611 and the flow rate display scale 612 and also serves as a rotation angle scale is provided. The minute opening indication scale 613 is a scale obtained by equally dividing 360 degrees around the axis of the input shaft 7 (for example, 16 divisions), and indicates the rotation angle (number of rotations) of the input shaft 7 by 1/16 of one rotation. The valve element opening corresponding to the rotation angle of the input shaft 7 is displayed. In the present embodiment, the full opening degree display scale 611, the flow rate display scale 612, and the minute opening degree display scale 613 are arranged on one scale board 614.

入力軸７にはキャップ７１を装着してあり、入力軸７とキャップ７１によって入力軸部を構成している。ケース５から露出している入力軸キャリア６の上面には全開度表示目盛６１１を指し示す全開度指針６２１ａおよび流量表示目盛６１２を指し示す流量指針６２１ｂを配置している。キャップ７１にはインジケータ７１１を設けており、インジケータ７１１には微小開度表示目盛６１３を指し示す微小開度指針６２２を配置している。インジケータ７１１はキャップ７１の軸心回りにおいて微小開度指針６２２の位置を調整可能であり、弁体２が開き始めて通水が始まる弁体開度において微小開度指針６２２が微小開度表示目盛６１３の「０度」を指すように設定する。全開度指針６２１ａと微小開度指針６２２とが開度指針部６２を構成する。   A cap 71 is attached to the input shaft 7, and the input shaft 7 and the cap 71 constitute an input shaft portion. On the upper surface of the input shaft carrier 6 exposed from the case 5, there are arranged a full opening indicator 621 a indicating the full opening indication scale 611 and a flow indicator 621 b indicating the flow indication scale 612. The cap 71 is provided with an indicator 711, and the indicator 711 is provided with a minute opening pointer 622 indicating a minute opening indication scale 613. The indicator 711 can adjust the position of the minute opening pointer 622 around the axis of the cap 71, and the minute opening pointer 622 has a minute opening indication scale 613 at the valve body opening at which the valve body 2 starts to open and water flow begins. Is set to indicate “0 degree”. The full opening pointer 621a and the minute opening pointer 622 constitute the opening guide portion 62.

図６に示すように、入力軸部の入力軸７と出力軸部の出力軸キャリア８の間には主動力伝達系が形成してあり、主動力伝達系は所定の減速比を形成する歯車列からなる。入力軸７の偏心部９には遊星歯車１０が回転自在に嵌合しており、遊星歯車１０は偏心部９の中心ＥＣを回転中心として回転する。   As shown in FIG. 6, a main power transmission system is formed between the input shaft 7 of the input shaft portion and the output shaft carrier 8 of the output shaft portion, and the main power transmission system is a gear that forms a predetermined reduction ratio. Consists of columns. A planetary gear 10 is rotatably fitted to the eccentric portion 9 of the input shaft 7, and the planetary gear 10 rotates around the center EC of the eccentric portion 9.

ケース５の内周面には遊星歯車１０に噛合する内歯車１１が設けてあり、内歯車１１と遊星歯車１０の間には所定の歯数差を設定している。内歯車１１には偏心部９の中心ＥＣから等距離の位置で、かつ中心ＥＣの周囲に等角度間隔で複数のピン穴１２が形成してある。   An internal gear 11 that meshes with the planetary gear 10 is provided on the inner peripheral surface of the case 5, and a predetermined number of teeth difference is set between the internal gear 11 and the planetary gear 10. A plurality of pin holes 12 are formed in the internal gear 11 at positions equidistant from the center EC of the eccentric portion 9 and at equal angular intervals around the center EC.

出力軸キャリア８は、上端面に入力軸７の下端を回転自在に保持する保持穴８１を有し、下端面に弁棒２の頭部に嵌合する嵌合穴８２を有している。ケース５の内周面に配置したストッパーリング８３が出力軸キャリア８の下端に摺接して出力軸キャリア８を軸心方向で抜け止めしている。   The output shaft carrier 8 has a holding hole 81 that rotatably holds the lower end of the input shaft 7 on the upper end surface, and a fitting hole 82 that fits the head of the valve stem 2 on the lower end surface. A stopper ring 83 disposed on the inner peripheral surface of the case 5 is in sliding contact with the lower end of the output shaft carrier 8 to prevent the output shaft carrier 8 from coming off in the axial direction.

図３に示すように、出力軸キャリア８は外方へ張り出した一対の回り止め部８４ａ、８４ｂを有し、ケース５には回り止め部８４ａ、８４ｂのそれぞれに当接する一対のストッパーボルト８５ａ、８５ｂを設けており、ケース５の内部に突出するストッパーボルト８５ａ、８５ｂの先端部がそれぞれ回り止め部８４ａ、８４ｂを、弁体２の全閉位置および全開位置に対応する位置で係止する。   As shown in FIG. 3, the output shaft carrier 8 has a pair of anti-rotation portions 84a and 84b protruding outward, and the case 5 has a pair of stopper bolts 85a that abut against the anti-rotation portions 84a and 84b, 85b is provided, and tip portions of stopper bolts 85a and 85b protruding into the case 5 respectively lock the rotation preventing portions 84a and 84b at positions corresponding to the fully closed position and the fully opened position of the valve body 2.

出力軸キャリア８には、入力軸７の軸心Ｃに等しい回転中心から等距離の位置で、かつ軸心Ｃの周囲に等角度間隔で複数のギアピン１３を設けており、ギアピン１３はピン穴１２に遊嵌し、かつ一部がピン穴１２の内周面に摺接している。また、ギアピン１３は上端が入力軸キャリア６に嵌合し、入力軸キャリア６と出力軸キャリア８との回転を同期させる。   The output shaft carrier 8 is provided with a plurality of gear pins 13 equidistant from the center of rotation equal to the axis C of the input shaft 7 and at equal angular intervals around the axis C. The gear pins 13 are pin holes. 12 is loosely fitted, and a part thereof is in sliding contact with the inner peripheral surface of the pin hole 12. Further, the upper end of the gear pin 13 is fitted to the input shaft carrier 6 to synchronize the rotation of the input shaft carrier 6 and the output shaft carrier 8.

以下、上記構成における作用を説明する。バルブを開閉する際には、操作ハンドル等で入力軸部のキャップ７１および入力軸７を回転させることで、所定の減速比をもって出力軸部の出力軸キャリア８および弁棒３が回転し、バルブの弁体２が所定の開度に開動する。   Hereinafter, the operation of the above configuration will be described. When opening and closing the valve, the input shaft cap 71 and the input shaft 7 are rotated by an operation handle or the like, so that the output shaft carrier 8 and the valve stem 3 of the output shaft portion are rotated with a predetermined reduction ratio. The valve body 2 is opened to a predetermined opening.

図６に示すように、入力軸７が軸心Ｃを回転中心として矢印Ａ方向に回転すると、偏心部９の中心ＥＣの移動に伴って遊星歯車１０が入力軸７の軸心Ｃの回りを矢印Ｂ方向に回動して公転する。遊星歯車１０は、ギアピン１３がピン穴１２に遊嵌し、遊星歯車１０の公転に伴ってピン穴１２がギアピン１３の軸心回りに移動することで、ギヤピン１３に阻害されることなく公転する。   As shown in FIG. 6, when the input shaft 7 rotates in the direction of arrow A about the axis C as the center of rotation, the planetary gear 10 moves around the axis C of the input shaft 7 as the center EC of the eccentric portion 9 moves. It rotates in the direction of arrow B and revolves. The planetary gear 10 revolves without being obstructed by the gear pin 13 because the gear pin 13 is loosely fitted in the pin hole 12 and the pin hole 12 moves around the axis of the gear pin 13 as the planetary gear 10 revolves. .

矢印Ｂ方向に公転する遊星歯車１０は内歯車１１に噛合するので、１公転する間に偏心部９の中心ＥＣを回転中心として矢印Ｃ方向に回転し、内歯車１１と遊星歯車１０の歯数差だけ自転する。遊星歯車１０が自転するとピン穴１２が偏心部９の中心ＥＣの回りを矢印Ｄの方向に移動し、ピン穴１２の内周面に押されてギアピン１３が入力軸７の軸心Ｃの回りを矢印Ｅ方向に移動する。   Since the planetary gear 10 that revolves in the direction of arrow B meshes with the internal gear 11, it rotates in the direction of arrow C around the center EC of the eccentric portion 9 during one revolution, and the number of teeth of the internal gear 11 and the planetary gear 10 Rotate by the difference. When the planetary gear 10 rotates, the pin hole 12 moves around the center EC of the eccentric portion 9 in the direction of arrow D and is pushed by the inner peripheral surface of the pin hole 12 so that the gear pin 13 rotates around the axis C of the input shaft 7. Is moved in the direction of arrow E.

ギアピン１３の移動に伴って出力軸キャリア８が回転するとともに、弁棒３が回転して弁体２が開動する。
この際に、出力軸キャリア８と同期して入力軸キャリア６が回転し、全開度指針６２１ａおよび流量指針６２１ｂが入力軸７の軸心Ｃの回りに回動して、出力軸キャリア８の回転角度に対応して現在の弁体開度を全開度表示目盛６１１において指し示すとともに流量表示目盛６１２において現在の通水流量を指し示す。流量指針６２１ｂが流量表示目盛６１２において弁体開度に対応する通水流量を図形情報として視覚的に指し示すので、操作者は一目で現在の通水流量の多寡を理解することができる。 As the gear pin 13 moves, the output shaft carrier 8 rotates, and the valve rod 3 rotates to open the valve body 2.
At this time, the input shaft carrier 6 rotates in synchronism with the output shaft carrier 8, and the full opening guide 621 a and the flow rate guide 621 b rotate around the axis C of the input shaft 7 to rotate the output shaft carrier 8. Corresponding to the angle, the current valve opening is indicated on the full opening indication scale 611 and the current water flow rate is indicated on the flow indication scale 612. Since the flow rate indicator 621b visually indicates the water flow rate corresponding to the valve body opening degree as the graphic information on the flow rate display scale 612, the operator can understand the current flow rate at a glance.

一方、入力軸７およびキャップ７１の回転に同期する微小開度指針６２２が入力軸７の軸心の回りに回動して、入力軸７の回転角度（回転数）を１／１６回転ずつ指し示すとともに、入力軸７の回転角度に対応して弁体開度を微小開度表示目盛６１３において指し示す。   On the other hand, the minute opening degree pointer 622 synchronized with the rotation of the input shaft 7 and the cap 71 rotates around the axis of the input shaft 7 to indicate the rotation angle (number of rotations) of the input shaft 7 by 1/16 rotation. At the same time, the valve opening degree is indicated on the minute opening degree display scale 613 corresponding to the rotation angle of the input shaft 7.

入力軸７の１回転は所定の減速比で出力軸キャリア８を所定回転角度に回転させる。換言すると出力軸キャリア８および弁棒３の回転角度に対して入力軸７およびキャップ７１が減速比の逆数倍の回転角度に回転する。   One rotation of the input shaft 7 rotates the output shaft carrier 8 at a predetermined rotation angle at a predetermined reduction ratio. In other words, the input shaft 7 and the cap 71 rotate to a rotation angle that is a reciprocal of the reduction ratio with respect to the rotation angle of the output shaft carrier 8 and the valve stem 3.

したがって、全開度指針６２１ａの回転角度が僅かで、全開度指針６２１ａが充水開度範囲６１１ａにある場合でも、微小開度指針６２２が減速比の逆数倍の回転角度に回転することで、全開度指針６２１ａが全開度表示目盛６１１において指し示す開度を、微小開度指針６２２が微小開度表示目盛６１３において拡大して指し示すことができる。例えば、充水開度範囲６１１ａにおいて入力軸７が１．８回転するのであれば、３６０°×１．８倍の範囲において拡大して表示できる。よって、弁体２の微小開度を容易に視認でき、かつ、弁体２を微小開度位置に正確に制御することができる。   Therefore, even when the rotation angle of the full opening guide 621a is small and the full opening guide 621a is in the charging opening range 611a, the minute opening guide 622 rotates to a rotation angle that is a reciprocal number times the reduction ratio. The opening degree indicated by the full opening degree indicator 621a on the full opening degree indication scale 611 can be indicated in an enlarged manner on the minute opening degree indication scale 613. For example, if the input shaft 7 rotates 1.8 times in the charging opening range 611a, it can be enlarged and displayed in a range of 360 ° × 1.8 times. Therefore, the minute opening degree of the valve body 2 can be easily visually recognized, and the valve body 2 can be accurately controlled to the minute opening position.
