Description
【０００１】[0001]
この考案は、例えばレジャー施設であるプール・浴槽・庭園の生けす・養殖用 水槽など（以下、単に水槽という）に用いられる圧送循環用給排水口金に関し、 特に流量調節可能な弁機能を有する給排水口金に関するものである。 The present invention relates to a water supply / drainage mouthpiece for pressure feeding and circulation used in, for example, a swimming pool, a bathtub, a living room in a garden, an aquarium for aquaculture (hereinafter simply referred to as an aquarium) which is a leisure facility, and particularly, a water supply / drainage mouthpiece having a valve function capable of adjusting a flow rate. It is about.
【０００２】[0002]
上記のような水槽では、従来より例えば図８で示すような給排水圧送循環装置 が用いられる。即ち、この給排水圧送循環装置は、水槽１の底壁や側壁（以下単 に槽壁２という）に複数の圧送循環用給排水口金１０を設け、これらの各給排水 口金１０に給水管５や排水管６を接続し、フィルター９を介して圧送ポンプ８の 圧送力で水３を強制循環させるように構成されている。 In the water tank as described above, conventionally, for example, a water supply / drainage pumping circulation device as shown in FIG. 8 is used. That is, this water supply / drainage pressure supply / circulation device is provided with a plurality of water supply / drainage caps 10 for pressure supply / circulation on the bottom wall or side wall of the water tank 1 (hereinafter, simply referred to as tank wall 2). 6 is connected, and the water 3 is forcibly circulated through the filter 9 by the pumping force of the pump 8.
【０００３】 そして、上記給排水口金１０としては、従来より例えば図９及び図１０で示す もの（以下底壁用給排水口金という）、あるいは図１１及び図１２で示すもの（ 以下側壁用給排水口金という）のが知られている。 底壁用給排水口金１０Ａは、図９及び図１０で示すように、口金本体１１を水 槽１の底壁２Ａに固設し、この口金本体１１の水入口１２に給水管５又は排水管 ６を接続し、口金本体１１の水出口１３に目皿１４をねじ込み固定し、この目皿 １４に２枚の開度調節板１５Ａ・１５Ｂをビス２１で回動自在に枢支させて成り 、第１の開度調節板１５Ａの扇状開口１６ａと第２の開度調節板１５Ｂの扇状開 口１６ｂとが重なる面積（開度）を調節するように構成されている。なお、入浴 中に足の指先が挿入するのを防止するため、上記目皿１４には比較的細い開口１ ６が形成されている。As the water supply / drainage mouthpiece 10 described above, for example, the one shown in FIGS. 9 and 10 (hereinafter referred to as the bottom wall water supply / drainage mouthpiece) or the one shown in FIGS. 11 and 12 (hereinafter referred to as the side wall water supply / drainage mouthpiece) has been used. Is known. As shown in FIGS. 9 and 10, a bottom wall water supply / drainage mouthpiece 10A has a mouthpiece main body 11 fixed to a bottom wall 2A of a water tank 1, and a water inlet pipe 5 or a drain pipe 6 at a water inlet 12 of the mouthpiece main body 11. , And the eyelet 14 is screwed and fixed to the water outlet 13 of the mouthpiece main body 11, and the eyelet 14 is rotatably supported by two opening degree adjusting plates 15A and 15B. It is configured to adjust the area (opening) where the fan-shaped opening 16a of the first opening adjustment plate 15A and the fan-shaped opening 16b of the second opening adjustment plate 15B overlap. A relatively thin opening 16 is formed in the eye plate 14 in order to prevent the toes of the toes from being inserted during bathing.
【０００４】 また、側壁用給排水口金１０Ｂは、口金本体１１が水槽１の側壁２Ｂに固設さ れるため、入浴中に足の指先が挿入するおそれはないので、図１１及び図１２で 示すように、上記目皿１４は設けられていない。なお、図９の底壁用給排水口金 １０Ａとの対比説明の便宜上、図１１では側壁２Ｂを水平線で表示している。 この側壁用給排水口金１０Ｂは、口金本体１１の水出口１３に第１の開度調節 板１５Ａをビス２３で固定し、この第１の開度調節板１５Ａに第２の開度調節板 １５Ｂをビス２１で回動自在に枢支させて成り、第１の開度調節板１５Ａの扇状 開口１６ａと第２の開度調節板１５Ｂの扇状開口１６ｂとが重なる面積（開度） を調節するように構成されている。なお、図１２中の符号２４は第２の開度調節 板１５Ｂに形成された開度調節用の円弧状長孔である。In addition, since the mouthpiece main body 11 of the side wall water supply / drainage mouthpiece 10B is fixed to the side wall 2B of the water tank 1, there is no risk of the toes of the toes being inserted during bathing. Therefore, as shown in FIG. 11 and FIG. In addition, the plate 14 is not provided. Note that the side wall 2B is shown by a horizontal line in FIG. 11 for convenience of explanation in comparison with the bottom wall water supply / drainage mouthpiece 10A. In this side wall supply / drainage mouthpiece 10B, a first opening adjusting plate 15A is fixed to the water outlet 13 of the mouthpiece main body 11 with screws 23, and a second opening adjusting plate 15B is attached to the first opening adjusting plate 15A. It is rotatably supported by a screw 21 to adjust the area (opening) where the fan-shaped opening 16a of the first opening adjustment plate 15A and the fan-shaped opening 16b of the second opening adjustment plate 15B overlap. Is configured. Reference numeral 24 in FIG. 12 is an arc-shaped elongated hole for adjusting the opening formed in the second opening adjusting plate 15B.
【０００５】 つまり、複数の浴槽を備えたレジャー施設などでは、各浴槽への給排水量と各 浴槽内での給排水口金からの給水吐出流速とを調節する必要がある。このため、 図８で示すように、各浴槽１ごとに給水管５と排水管６とを埋設配管し、給水管 ５と排水管６とにそれぞれ流量調節弁５ａ・６ａを設けて給排水量を調節し、給 排水口金の前記開度調節板１５Ａ・１５Ｂの扇状開口１６ａ・１６ｂの開度を調 節することにより、給水吐出流速を調節していた。なお、図８中の２点鎖線Ｋは 給水管５及び排水管６の埋設領域を示し、この埋設領域Ｋ内では開閉弁操作がで きないため、流量調節弁５ａ・６ａを設けることはできず、これらの流量調節弁 ５ａ・６ａは、埋設領域Ｋ外に設けられている。That is, in a leisure facility having a plurality of bathtubs, it is necessary to adjust the amount of water supply and drainage to each bathtub and the flow rate of water supply and discharge from the water supply and drainage mouthpiece in each bathtub. Therefore, as shown in FIG. 8, the water supply pipe 5 and the drainage pipe 6 are buried in each bathtub 1, and the water supply pipe 5 and the drainage pipe 6 are provided with flow rate adjusting valves 5a and 6a, respectively, to control the water supply and drainage amount. The feed water discharge flow velocity is adjusted by adjusting and adjusting the openings of the fan-shaped openings 16a and 16b of the opening adjustment plates 15A and 15B of the water supply / drainage mouthpiece. The two-dot chain line K in FIG. 8 indicates the buried area of the water supply pipe 5 and the drainage pipe 6, and since the opening / closing valve cannot be operated in this buried area K, the flow rate control valves 5a and 6a cannot be provided. First, these flow rate control valves 5a and 6a are provided outside the buried region K.
【０００６】[0006]
上記従来技術では、各浴槽１ごとにそれぞれ給水管５と排水管６とを重複して 埋設配管しなければならず、しかも、埋設領域Ｋ外の各給水管５・排水管６にそ れぞれ流量調節弁５ａ・６ａを設ける必要があるため、給水管５・排水管６・流 量調節弁５ａ・６ａを重複配置する分だけ設備工事費が高くつく。 In the above-mentioned conventional technique, the water supply pipe 5 and the drain pipe 6 must be overlapped and buried in each of the bathtubs 1, and each of the water supply pipe 5 and the drain pipe 6 outside the burying area K must be provided. Since it is necessary to provide the flow rate control valves 5a and 6a, the facility construction cost is high due to the overlapping arrangement of the water supply pipe 5, the drain pipe 6, and the flow rate control valves 5a and 6a.
【０００７】 また、流量調節弁５ａ・６ａで給排水量を調節し、開度調節板１５Ａ・１５Ｂ で給水吐出流速を調節する構造であるから、給排水量の調節と給水吐出流速の調 節が二度手間で煩雑になるうえ、開度調節板１５Ａ・１５Ｂが水出口１３に接近 して設けられているため、開度調節によっては給水時の吐出流速が大きくなり、 人体に不快感を生じさせる。Further, since the structure is such that the flow rate control valves 5a and 6a adjust the water supply / drainage amount and the opening degree control plates 15A and 15B adjust the water supply discharge velocity, there are two adjustments of the water supply / drainage amount and the water discharge velocity. Besides, the opening adjustment plates 15A and 15B are provided close to the water outlet 13, and the discharge flow velocity at the time of water supply becomes large depending on the opening adjustment, which causes discomfort to the human body. .
【０００８】 しかも、２つの開度調節板１５Ａ・１５Ｂの中心を回動中心として両者を相対 回転させ、扇状開口１６ａ・１６ｂの重なり（開度）を調節する構成であるから 、この開度調節板１５Ａ・１５Ｂでは給排水を完全に締め切れない。 つまり、給排水口金の近傍の埋設領域Ｋ内には流量調節弁５ａ・６ａを設ける ことはできないため、配管系統の加圧漏水テストでは、各開度調節板１５Ａ・１ ５Ｂを閉止栓と交換して口金本体１１の水出口１３を閉止しなければならず、そ の交換が大変煩わしい。Moreover, since the two opening adjustment plates 15A and 15B are rotated relative to each other with the center thereof as the center of rotation, the overlapping (opening) of the fan-shaped openings 16a and 16b is adjusted. Water supply and drainage cannot be completely closed with plates 15A and 15B. In other words, since the flow rate control valves 5a and 6a cannot be installed in the buried area K near the water supply / drainage mouthpiece, in the pressurized leak test of the piping system, the opening control plates 15A and 15B are replaced with the closing plugs. The water outlet 13 of the base body 11 has to be closed, and the replacement thereof is very troublesome.
【０００９】 また、従来の上記給排水口金１０Ａ・１０Ｂは、目皿１４を有する底壁用給排 水口金１０Ａと目皿１４を有しない側壁用給排水口金１０Ｂとを、浴槽の槽壁２ に応じて使い分ける必要があり、設備工事等に伴う在庫管理が大変煩わしい。Further, in the conventional water supply / drainage mouthpieces 10A and 10B, a bottom wall water supply / drainage mouthpiece 10A having a plate 14 and a side wall water supply / drainage mouthpiece 10B having no plate 14 are provided according to the bath wall 2 of the bathtub. It is necessary to use them properly and it is very troublesome to manage the inventory due to equipment construction.
【００１０】 本考案はこのような事情を考慮してなされたもので、 各浴槽１ごとに給水管５・排水管６・流量調節弁５ａ・６ａを重複配置する する必要を無くし、設備工事費を低減すること、 給排水量の調節と給水吐出流速の調節を一度で簡単に済ませ、給排水口金か らの吐出流速を緩やかにして、身体に不快感を生じないようにすること、 圧送循環用給排水口金１０により給排水を容易に締め切れるようにして、配 管の加圧漏水テストでは、開度調節板を閉止栓と交換する手間を無くすること、 従来の底壁用給排水口金と側壁用給排水口金との使い分けを不要にし、在庫 管理を容易にすること、 を技術課題とする。The present invention has been made in consideration of such circumstances, and eliminates the need for arranging the water supply pipe 5, the drain pipe 6, and the flow rate control valves 5a, 6a in each bathtub 1 in duplicate, thereby reducing the cost of equipment construction. The flow rate of water supply and drainage and the flow rate of water supply and discharge can be adjusted easily at one time, and the flow rate of discharge from the water supply and drainage mouth is made gentle so as not to cause discomfort to the body. The mouthpiece 10 can be used to easily close the water supply and drainage, and in the pressure leak test of the pipe, there is no need to replace the opening adjustment plate with the stopper, and the conventional bottom wall water supply and drainage mouthpiece and side wall water supply and drainage mouthpiece It is a technical issue to make it easier to manage inventory by eliminating the need for proper use between the two.
【００１１】[0011]
上記課題を解決するために、本考案が採用した手段は、 容器状の口金本体１１の下面に水入口１２を開口するとともに、この口金本体 １１の上面に水出口１３を開口し、上記水入口１２の周壁部１１ａを配管接続部 として下向きに連出させ、上記水出口１３に目皿１４を固設して構成した水槽の 圧送循環用給排水口金において、 上記口金本体１１の内部で上記水入口１２の上側に弁室Ｖを形成して、弁室Ｖ 内に流量調節弁体３０・４０を設け、 この流量調節弁体３０・４０は、弁体支持具２５・４５の弁軸３２・４２に固 定して口金本体１１に支持させるとともに、この弁軸３２・４２を上記水出口１ ３側より回動操作可能に構成し、 上記流量調節弁体３０・４０を流量調節可能、かつ閉弁操作可能に構成したこ とをことを要旨とするものである。 In order to solve the above problems, the means adopted by the present invention is to open a water inlet 12 on the lower surface of a container-shaped mouthpiece body 11 and to open a water outlet 13 on the upper surface of the mouthpiece body 11. In the water supply / drainage mouthpiece for pumping circulation of the water tank, which is formed by connecting downwardly the peripheral wall portion 11a of 12 as the pipe connection portion and fixing the plate 14 to the water outlet 13, the water inlet inside the mouthpiece main body 11 The valve chamber V is formed on the upper side of the valve 12, and the flow rate control valve bodies 30 and 40 are provided in the valve chamber V 1. The flow rate control valve bodies 30 and 40 are the valve shafts 32 and 42 of the valve body support tools 25 and 45. The valve shafts 32 and 42 are rotatably operated from the water outlet 13 side, and the flow rate adjusting valve bodies 30 and 40 can be adjusted and closed. The main point is that the valve is configured to be operable. It is intended.
【００１２】[0012]
図１を参照しつつ説明すると、本考案は以下のように作用する。 上記口金本体１１の内部で、上記水入口１２の上側に形成された弁室Ｖ内には 、流量調節弁体３０が設けられている。この流量調節弁体３０は、弁体支持具２ ５・４５の弁軸３２・４２に固定されており、この弁軸３２・４２を上記水出口 １３側より回動操作することにより、上記流量調節弁体３０の開度を調節して流 量調節及び閉弁することができる。 なお、流量調節弁体３０の開度に比例して流量が設定されるが、弁室Ｖから目 皿１４に至る間に水の流速は減衰するので、口金本体１１の開口１６より吐出す る水の吐出流速は、従来例に比較して大変緩やかになる。 Referring to FIG. 1, the present invention operates as follows. A flow rate adjusting valve body 30 is provided inside the mouthpiece main body 11 and inside a valve chamber V formed above the water inlet 12. The flow rate control valve body 30 is fixed to the valve shafts 32 and 42 of the valve body support 25 and 45, and the flow rate is controlled by rotating the valve shafts 32 and 42 from the water outlet 13 side. It is possible to adjust the flow rate and close the valve by adjusting the opening degree of the control valve body 30. Although the flow rate is set in proportion to the opening degree of the flow rate control valve body 30, since the flow velocity of water is attenuated from the valve chamber V to the plate 14, it is discharged from the opening 16 of the base body 11. The discharge flow velocity of water becomes very gentle as compared with the conventional example.
【００１３】[0013]
本考案は上記構成により、以下のような効果を奏する。 流量調節弁体３０の開度を調節して閉弁操作することにより、各浴槽１毎に 重複して給水管５・排水管６・流量調節弁５ａ・６ａを設ける必要が無くなり 、設備工事費を大幅に低減することができる。 流量調節弁体３０の開度を調節して流量調節操作及び閉弁操作することがで きるので、給排水量の調節と給水吐出流速の調節を一度で簡単に済ませ、また 、上記のように給排水口金からの吐出流速が緩やかになり、身体に不快感を生 ることもない。 流量調節弁体３０の開度を調節して簡単に閉弁操作することができるので、 配管の加圧漏水テストでは、開度調節板を閉止栓と交換する手間を無くするこ とができる。 本考案では、一つの給排水口金で底壁と側壁とに併用することができるので 、従来例のように底壁用と側壁用とを使い分ける必要がなく、在庫管理が容易 になる。 The present invention has the following effects due to the above configuration. By adjusting the opening degree of the flow rate control valve body 30 and performing the closing operation, it is not necessary to provide the water supply pipe 5, the drainage pipe 6, and the flow rate control valves 5a and 6a in duplicate for each bathtub 1, and the facility construction cost can be reduced. Can be significantly reduced. Since it is possible to adjust the flow rate and close the valve by adjusting the opening degree of the flow control valve body 30, it is possible to easily adjust the amount of water supply and drainage and the flow rate of water supply and discharge at one time. The discharge flow rate from the mouthpiece is gentle, and there is no discomfort to the body. Since the opening degree of the flow rate adjusting valve body 30 can be adjusted and the valve closing operation can be easily performed, it is possible to eliminate the trouble of replacing the opening degree adjusting plate with the closing plug in the pressurized water leakage test of the pipe. In the present invention, one water supply / drainage mouthpiece can be used for both the bottom wall and the side wall, so that it is not necessary to use the bottom wall and the side wall separately as in the conventional example, and the inventory management becomes easy.

以下、本考案の実施例を図面に基づいてさらに詳しく説明する。 図１は本考案の第１の実施例に係る圧送循環用給排水口金の縦断面図、図２は その平面図である。 この圧送循環用給排水口金１０は、容器状の口金本体１１と、この口金本体１ １の水出口１３に固設された目皿１４と、口金本体１１の内部で上記水入口１２ の上側に形成した弁室Ｖと、この弁室Ｖ内に設けられた流量調節弁体３０と、この 流量調節弁体３０を口金本体１１に支持する弁体支持具２５とを具備して成る。 Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a vertical sectional view of a water supply / drainage pipe for pressure feeding and circulation according to a first embodiment of the present invention, and FIG. 2 is a plan view thereof. The water supply / drainage mouthpiece 10 for pressure feeding and circulation is formed on the upper side of the water inlet 12 inside the mouthpiece body 11 and the eyelet 14 fixed to the water outlet 13 of the mouthpiece body 11. The valve chamber V, the flow rate control valve body 30 provided in the valve chamber V, and the valve body support 25 for supporting the flow rate control valve body 30 on the base body 11.
【００１５】 水槽１の槽壁２に埋設される上記口金本体１１は、図１で示すように、その下 面に水入口１２を開口するとともに、上面に水出口１３を開口し、この水入口１ ２の周壁部１１ａを配管接続部として下向きに連出させ、この水入口１２の周壁 部１１ａ内に雌ネジ１２ａを形成し、この雌ネジ１２ａの奥端側内周部に環状の 弁座１８を形成し、上記水出口１３の周壁部１１ｂ内に雌ネジ１３ａを形成して 構成されている。As shown in FIG. 1, the mouthpiece main body 11 embedded in the tank wall 2 of the water tank 1 has a water inlet 12 opened on the lower surface and a water outlet 13 opened on the upper surface. The peripheral wall portion 11a of 12 is continuously extended downward as a pipe connecting portion, and a female screw 12a is formed in the peripheral wall portion 11a of the water inlet 12. An annular valve seat is formed on the inner peripheral portion of the female screw 12a. 18 is formed, and a female screw 13a is formed in the peripheral wall portion 11b of the water outlet 13.
【００１６】 上記水入口１２には、給水管５又は排水管６が接続され、上記水出口１３には 、その外周部に雄ネジを形成した目皿１５がねじ込み固定されている。 また、上記弁室Ｖの内部で、上記弁座１８の上側には、流量調節弁体３０が設 けられている。この流量調節弁体３０は、弁体支持具２５を介して口金本体１１ に高さ調節可能に支持され、この流量調節弁体３０の周辺部には、環状の０リン グより成る弁面３１が形成され、上記弁座１８とこの弁面３１との間に流量設定 用流通隙間Ｓが形成される。A water supply pipe 5 or a drain pipe 6 is connected to the water inlet 12, and a perforated plate 15 having a male screw formed on the outer peripheral portion thereof is screwed and fixed to the water outlet 13. Further, inside the valve chamber V, a flow rate control valve body 30 is provided above the valve seat 18. The flow rate control valve body 30 is supported by the mouthpiece main body 11 via a valve body support 25 so that the height of the flow rate control valve body 30 can be adjusted. Is formed, and a flow rate setting flow gap S is formed between the valve seat 18 and the valve surface 31.
【００１７】 上記弁体支持具２５は、口金本体１１内の中央部に位置する上下向きのボス部 ２６から複数本の腕２８を半径方向に連出して、各腕２８の先端部２８ａを口金 本体１１の周壁内部に形成した腕支持ボス１９にボルト２９で固定し、上記中央 部のボス部２６内にネジ孔２７を上下に貫通して構成されている。In the valve body support 25, a plurality of arms 28 are radially extended from a vertically oriented boss portion 26 located in a central portion of the mouthpiece main body 11, and tip portions 28 a of the arms 28 are connected to the mouthpiece. The arm support boss 19 formed inside the peripheral wall of the main body 11 is fixed with a bolt 29, and a screw hole 27 is vertically penetrated in the central boss portion 26.
【００１８】 一方、上記流量調節弁体３０は、その中央部から上向きにネジ弁軸３２を延出 し、このネジ弁軸３２の上部３２ａを上記ボス部２６のネジ孔２７に下からねじ 嵌合するとともに、このネジ孔２７に上から筒状のロックボルト３５をねじ嵌合 して、このロックボルト３５でネジ弁軸３２を固定するように構成されている。On the other hand, the flow rate control valve body 30 has a threaded valve shaft 32 extending upward from a central portion thereof, and an upper portion 32 a of the threaded valve shaft 32 is screwed into a screw hole 27 of the boss portion 26 from below. At the same time, the cylindrical lock bolt 35 is screwed into the screw hole 27 from above, and the screw valve shaft 32 is fixed by the lock bolt 35.
【００１９】 上記ロックボルト３５の上面には、回転操作用としてドライバ操作用切溝３７ が形成され、上記ネジ弁軸３２の上面には、回転操作部として同様にドライバ操 作用切溝３４が形成され、この切溝３４はロックボルト３５の筒孔３６に臨ませ て形成されている。つまり、ロックボルト３５の筒孔３６にドライバを挿入して 上記ネジ弁軸３２を回転操作し、上記流量調節弁体３０の高さを調節した後、上 記ロックボルト３５でネジ弁軸３２を固定することにより、上記弁座１８と弁面 ３１との間に所定の流通隙間Ｓが形成される。なお、上記ネジ弁軸３２の上面に は、回転操作部として切溝３４に限らず、例えば６角ドライバ操作用の６角穴を 形成しても良い。A driver operation cutout groove 37 is formed on the upper surface of the lock bolt 35 for rotation operation, and a driver operation cutout groove 34 is similarly formed on the upper surface of the screw valve shaft 32 as a rotation operation portion. The cut groove 34 is formed so as to face the cylindrical hole 36 of the lock bolt 35. That is, after inserting a screwdriver into the cylindrical hole 36 of the lock bolt 35 and rotating the screw valve shaft 32 to adjust the height of the flow rate control valve body 30, the screw valve shaft 32 is locked with the lock bolt 35. By fixing, a predetermined flow gap S is formed between the valve seat 18 and the valve surface 31. The screw valve shaft 32 may have a hexagonal hole for operating a hexagonal driver, for example, as the rotary operation portion, not limited to the cut groove 34.
【００２０】 上記口金本体１１の水出口１３に固設された目皿１４には、図２で示すように 、多数の開口１６が形成され、目皿１４の中央部にはドライバ挿入孔１７があけ られており、このドライバ挿入孔１７よりドライバを挿入してネジ弁軸３２やロ ックボルト３５を回転操作するように構成されている。 この実施例によれば、目皿１４のドライバ挿入孔１７よりドライバを挿入して ネジ軸３２やロックボルト３５を回転操作することにより、弁座１８と弁面３１ との間の流量設定用流通隙間Ｓ（開度）を自在に設定し、又は閉止することがで きる。なお、流量調節弁体３０の開度に比例して流量が設定されるが、弁室Ｖか ら目皿１４に至る間に水の流速は減衰するので、口金本体１１の開口１６より吐 出する水の吐出流速は、従来例に比較して大変緩やかになる。As shown in FIG. 2, a large number of openings 16 are formed in the plate 14 fixed to the water outlet 13 of the mouthpiece main body 11, and a driver insertion hole 17 is formed in the center of the plate 14. The screw valve shaft 32 and the lock bolt 35 are rotationally operated by inserting a driver through the driver insertion hole 17. According to this embodiment, a driver is inserted through the driver insertion hole 17 of the perforated plate 14 and the screw shaft 32 and the lock bolt 35 are rotated, so that the flow rate setting distribution between the valve seat 18 and the valve face 31 is achieved. The gap S (opening) can be set freely or can be closed.
