The opening indication mechanisms 102, 302, 402, 502 are housed inside the handles 100, 300, 400, 500. The handles 100, 300, 400, 500 have the driving-side internal gears 112 b, 312 b, 412 b and a plurality of viewing windows 130, 330, 430. The plurality of viewing windows 130, 330, and 430 are disposed so as to surround the valve stem 28. The opening display mechanisms 102, 302, 402, 502 have opening display members 120, 320, 420, 520, and drive gear portions 122, 322, 422, 522. The opening degree display members 120, 320, 420, and 520 are disposed between the valve rod 28 and the viewing windows 130, 330, and 430. The opening display members 120, 320, 420, and 520 have driven internal gears 120c, 320c, 420c, and 520c. The opening display members 120, 320, 420, and 520 rotate around the valve rod 28. On the opening display members 120, 320, 420, and 520, information that can be viewed from outside the viewing windows 130, 330, and 430 is displayed. The drive gear portions 122, 322, 422, and 522 receive torque from the driving-side internal gears 112b, 312b, and 412b of the handles 100, 300, 400, and 500, and are located on the driven side of the opening indication members 120, 320, 420, and 520. By applying torque to the gears 120c, 320c, 420c, and 520c, the opening degree display members 120, 320, 420, and 520 are driven so that the rotational speed is lower than that of the handles 100, 300, 400, and 500.

駆動歯車部122,322,422,522が、ハンドル100,300,400,500の原動側内歯車112b,312b,412bからトルクを受けて開度表示部材120,320,420,520の従動側内歯車120c,320c,420c,520cへトルクを与える。内歯車からトルクを受けて別の内歯車へトルクを与えることにより、開度表示部材120,320,420,520の回転速度とハンドル100,300,400,500の回転速度との差を抑えることができる。その差を抑えることができるので、ハンドル100,300,400,500を回転させたとき、複数の覗き窓130,330,430それぞれから視認できる情報は、ハンドル100,300,400,500の回転に応じて少しずつ変化する。複数の覗き窓130,330,430それぞれから視認できる情報が少しずつ変化するので、ハンドル100,300,400,500に複数の覗き窓130,330,430を設け、それらの各々から情報を視認可能とすることができる。複数の覗き窓130,330,430の各々から情報を視認可能なので、側面から開閉状態を視認しようとするとき、様々な方向からそれを可能とすることができる。   The drive gears 122, 322, 422, 522 receive torque from the driving-side internal gears 112 b, 312 b, 412 b of the handles 100, 300, 400, 500, and follow the insides of the opening indication members 120, 320, 420, 520. Torque is applied to the gears 120c, 320c, 420c, and 520c. By receiving torque from the internal gear and applying torque to another internal gear, the difference between the rotational speed of the opening degree display members 120, 320, 420, and 520 and the rotational speed of the handles 100, 300, 400, and 500 is suppressed. Can do. Since the difference can be suppressed, when the handles 100, 300, 400, 500 are rotated, the information that can be visually recognized from the plurality of viewing windows 130, 330, 430 is the rotation of the handles 100, 300, 400, 500. It changes little by little. Since the information visible from each of the plurality of observation windows 130, 330, and 430 changes little by little, the plurality of observation windows 130, 330, and 430 are provided on the handles 100, 300, 400, and 500, and the information can be visually recognized from each of them. It can be. Since information can be visually recognized from each of the plurality of viewing windows 130, 330, and 430, when viewing the open / closed state from the side, it can be performed from various directions.

また、上述した開度表示部材の従動側内歯車120c,320cの歯数がハンドルの原動側内歯車112b,312bの歯数より少なく、かつ、駆動歯車部が外歯車122,322を有することが望ましい。この場合、外歯車122,322は、原動側内歯車112b,312bおよび従動側内歯車120c,320cと噛合う。   Further, the number of teeth of the driven side internal gears 120c and 320c of the opening degree display member described above is smaller than the number of teeth of the driving side internal gears 112b and 312b of the handle, and the drive gear unit has the external gears 122 and 322. desirable. In this case, the external gears 122 and 322 mesh with the driving side internal gears 112b and 312b and the driven side internal gears 120c and 320c.

従動側内歯車120c,320cの歯数が原動側内歯車112b,312bの歯数より少なく、かつ、1つの外歯車122,322が原動側内歯車112b,312bおよび従動側内歯車120c,320cという2種類の歯車と噛合うとき、従動側内歯車120c,320cの歯数と原動側内歯車112b,312bの歯数との差はかなり少なくなる。従動側内歯車120c,320cの歯数と原動側内歯車112b,312bの歯数との差がかなり少ないので、そうでない場合に比べ、開度表示部材120,320の回転速度とハンドル100,300の回転速度との差をより少なくすることができる。これにより、覗き窓130,330を多く設けても、それらの各々から情報を視認可能とすることができる。その結果、より様々な方向から開閉状態を視認できる。   The number of teeth of the driven side internal gears 120c, 320c is less than the number of teeth of the driven side internal gears 112b, 312b, and one external gear 122, 322 is called the driven side internal gears 112b, 312b and the driven side internal gears 120c, 320c. When meshing with two types of gears, the difference between the number of teeth of the driven side internal gears 120c and 320c and the number of teeth of the driven side internal gears 112b and 312b is considerably reduced. Since the difference between the number of teeth of the driven-side internal gears 120c and 320c and the number of teeth of the driving-side internal gears 112b and 312b is considerably small, the rotational speed of the opening degree display members 120 and 320 and the handles 100 and 300 are not compared to the other cases. The difference with the rotational speed of the can be reduced. Thereby, even if many viewing windows 130 and 330 are provided, information can be visually recognized from each of them. As a result, the open / closed state can be visually recognized from various directions.

また、上述した駆動歯車部422が、外筒噛合部450と、表示部材噛合部452とを有していることが望ましい。外筒噛合部450はハンドル400の原動側内歯車412bに噛合う。表示部材噛合部452は、外筒噛合部450と同軸上に設けられる。表示部材噛合部452は、外筒噛合部450に同調して動く。表示部材噛合部452は、開度表示部材420の従動側内歯車420cに噛合う。この場合、表示部材噛合部452のうち従動側内歯車420cに噛合う部分の歯数が、外筒噛合部450のうち原動側内歯車412bに噛合う部分の歯数より少ない。   Further, it is desirable that the above-described drive gear portion 422 has an outer cylinder engaging portion 450 and a display member engaging portion 452. The outer cylinder meshing portion 450 meshes with the driving side internal gear 412 b of the handle 400. The display member engagement portion 452 is provided coaxially with the outer cylinder engagement portion 450. The display member engagement portion 452 moves in synchronization with the outer cylinder engagement portion 450. The display member meshing portion 452 meshes with the driven side internal gear 420 c of the opening degree display member 420. In this case, the number of teeth of the portion of the display member meshing portion 452 that meshes with the driven side internal gear 420c is smaller than the number of teeth of the portion of the outer cylinder meshing portion 450 that meshes with the driving side internal gear 412b.

また、上述したハンドル400が、固定部416と、接続筒部410とを有していることが望ましい。固定部416は、弁棒28に取付けられている。固定部416および弁棒28が接続筒部410を貫通する。固定部416は、固定側凹凸部416aを有している。固定側凹凸部416aは、弁棒28の回転軸に沿って延びる。接続筒部410は、接続側凹凸部410aを有している。接続側凹凸部410aは、固定側凹凸部416aに噛合う。   Moreover, it is desirable that the handle 400 described above has a fixing portion 416 and a connecting tube portion 410. The fixed portion 416 is attached to the valve stem 28. The fixed portion 416 and the valve stem 28 penetrate the connecting tube portion 410. The fixing portion 416 has a fixing side uneven portion 416a. The fixed-side uneven portion 416 a extends along the rotation axis of the valve stem 28. The connection cylinder part 410 has the connection side uneven | corrugated | grooved part 410a. The connection side uneven part 410a meshes with the fixed side uneven part 416a.

固定部416および弁棒28が接続筒部410を貫通し、かつ、接続側凹凸部410aが固定側凹凸部416aに噛合うと、ハンドル400を回したときは弁棒28も回る上に、ハンドル400を弁棒28へ着脱できるようになる。しかも、接続側凹凸部410aが固定側凹凸部416aに噛合うので、覗き窓の向きを調整することが可能となる。   When the fixed portion 416 and the valve stem 28 penetrate the connecting tube portion 410 and the connection-side uneven portion 410a meshes with the fixed-side uneven portion 416a, when the handle 400 is rotated, the valve rod 28 also rotates. Can be attached to and detached from the valve stem 28. In addition, since the connection-side uneven portion 410a meshes with the fixed-side uneven portion 416a, the direction of the viewing window can be adjusted.

It leads to the gas outlet 234. A safety valve 38 is provided in the outlet passage 238 branched from the middle portion of the inlet passage 226. The closing member 24 is accommodated in the closing valve chamber 230. A male screw is provided on the outer peripheral portion of the closing member 24. A female screw is provided on the inner wall of the shut-off valve chamber 230. Since the male screw and the female screw are fitted, the closing member 24 can freely move up and down in the closing valve chamber 230. Therefore, the synthetic resin valve body 240 fitted in the closing member 24 can be in contact with or away from the closing valve seat 228.

弁箱22のうち閉止弁室230の上側の部分にネジ孔236が形成される。そのネジ孔236に弁蓋26がネジ止めされる。弁蓋26が有する孔を弁棒28が貫通する。弁蓋26の孔の内周面と弁棒28の外周面との間は、2つのOリング30によってシールされる。これにより、弁棒28は、弁蓋26に対して時計回りにも反時計回りにも回転できる。弁棒28の下部が閉止部材24に連結される。弁棒28の上部にカップ型ハンドル100が設けられる。作業者は、外筒112を指でつかんでカップ型ハンドル100にトルクを与える。これによりカップ型ハンドル100が回ると弁棒28も回る。弁棒28が回ると閉止部材24も回る。   A screw hole 236 is formed in the valve box 22 in the upper part of the closing valve chamber 230. The valve lid 26 is screwed into the screw hole 236. The valve stem 28 passes through the hole of the valve lid 26. The inner peripheral surface of the hole of the valve lid 26 and the outer peripheral surface of the valve stem 28 are sealed by two O-rings 30. Thereby, the valve stem 28 can rotate clockwise or counterclockwise with respect to the valve lid 26. The lower part of the valve stem 28 is connected to the closing member 24. A cup-type handle 100 is provided on the upper portion of the valve stem 28. An operator applies torque to the cup-type handle 100 by holding the outer cylinder 112 with a finger. As a result, when the cup handle 100 rotates, the valve stem 28 also rotates. When the valve stem 28 rotates, the closing member 24 also rotates.

カップ型ハンドル100は、内筒110と外筒112とこれらを連結する頂壁114と弁棒28に固定される固定部116とを有する。内筒110と外筒112と頂壁114と固定部116とは、不透明な合成樹脂によって一体成形されている。カップ型ハンドル100の内筒110内に、ハンドルナット34と押上バネ36とが設けられる。その押上バネ36の弾性力によって、弁棒28は押上げられる。カップ型ハンドル100のうち外筒112から頂壁114にかけての箇所には、図2に示すように、5箇所の覗き窓130が設けられる。また、図3および図5に示すように、外筒112の内周面には原動側内歯車112bが形成されている。   The cup-type handle 100 includes an inner cylinder 110, an outer cylinder 112, a top wall 114 that connects them, and a fixing portion 116 that is fixed to the valve stem 28. The inner cylinder 110, the outer cylinder 112, the top wall 114, and the fixing portion 116 are integrally formed of an opaque synthetic resin. A handle nut 34 and a push-up spring 36 are provided in the inner cylinder 110 of the cup-type handle 100. The valve rod 28 is pushed up by the elastic force of the push-up spring 36. As shown in FIG. 2, five viewing windows 130 are provided in a portion from the outer cylinder 112 to the top wall 114 in the cup-type handle 100. As shown in FIGS. 3 and 5, a driving-side internal gear 112 b is formed on the inner peripheral surface of the outer cylinder 112.

図1に示すように、カップ型ハンドル100内部には開度表示機構102が収容される。開度表示機構102は、開度表示部材120と、外歯車122(本実施形態における駆動歯車部である)と、保持部材124とを有している。   As shown in FIG. 1, an opening degree display mechanism 102 is accommodated inside the cup-type handle 100. The opening display mechanism 102 includes an opening display member 120, an external gear 122 (which is a drive gear portion in the present embodiment), and a holding member 124.

開度表示部材120は、内筒110と外筒112との隙間つまり弁棒28と覗き窓130との間に配置される。後述する説明から明らかな通り、開度表示部材120は弁棒28の周りを回転する。図1に示す通り、開度表示部材120は、筒部120aと、斜面部120bとを有する。筒部120aは弁棒28を取囲むよう配置される。斜面部120bは外歯車122に覆い被さるように筒部120aの一端に設けられる。図示していないが、筒部120aと斜面部120bとは、赤と青とに塗分けられている。これらの色は覗き窓130の外から視認できる。覗き窓130の外から視認できるため、これらの色が、閉止弁座228に対する弁体240の開き具合(開度)を示す情報となっている。また、図4および図5に示す通り、開度表示部材120は、従動側内歯車120cをさらに有する。従動側内歯車120cは筒部120aの内周に設けられる。従動側内歯車120cの歯数はカップ型ハンドル100の原動側内歯車112bの歯数よりも少ない。本実施形態の場合、開度表示部材120の従動側内歯車120cの歯数は「45」である。カップ型ハンドル100の原動側内歯車112bの歯数は「48」である。   The opening degree display member 120 is disposed between the inner cylinder 110 and the outer cylinder 112, that is, between the valve rod 28 and the viewing window 130. As will be apparent from the following description, the opening degree display member 120 rotates around the valve stem 28. As shown in FIG. 1, the opening degree display member 120 has a cylindrical portion 120a and a slope portion 120b. The cylindrical portion 120a is disposed so as to surround the valve stem 28. The slope portion 120b is provided at one end of the cylindrical portion 120a so as to cover the external gear 122. Although not shown, the cylindrical portion 120a and the slope portion 120b are painted in red and blue. These colors are visible from outside the viewing window 130. These colors are information indicating the degree of opening (opening degree) of the valve element 240 with respect to the closing valve seat 228 since it is visible from the outside of the viewing window 130. As shown in FIGS. 4 and 5, the opening degree display member 120 further includes a driven side internal gear 120c. The driven side internal gear 120c is provided on the inner periphery of the cylindrical portion 120a. The number of teeth of the driven side internal gear 120 c is smaller than the number of teeth of the driven side internal gear 112 b of the cup-type handle 100. In the case of this embodiment, the number of teeth of the driven side internal gear 120c of the opening degree display member 120 is “45”. The number of teeth of the driving-side internal gear 112b of the cup-type handle 100 is “48”.

図3に示すとおり、外歯車122は外筒112の原動側内歯車112bに噛合う。図4に示すとおり、外歯車122は開度表示部材120の従動側内歯車120cとも噛合う。これにより、外歯車122は原動側内歯車112bからトルクを受けて従動側内歯車120cへトルクを与えることとなる。トルクを与えることにより、外歯車122はカップ型ハンドル100よりも回転速度が低くなるよう開度表示部材120を駆動することとなる。その結果、上述したとおり、開度表示部材120は弁棒28の周りを回転する。開度表示部材120の回転速度がカップ型ハンドル100よりも低いのは、開度表示部材120の従動側内歯車120cの歯数がカップ型ハンドル100の原動側内歯車112bの歯数よりも少ないためである。ちなみに、外歯車122の歯数は「8」である。   As shown in FIG. 3, the external gear 122 meshes with the driving-side internal gear 112 b of the outer cylinder 112. As shown in FIG. 4, the external gear 122 meshes with the driven-side internal gear 120 c of the opening degree display member 120. As a result, the external gear 122 receives torque from the driving side internal gear 112b and applies torque to the driven side internal gear 120c. By applying torque, the external gear 122 drives the opening degree display member 120 so that the rotational speed is lower than that of the cup-type handle 100. As a result, the opening degree display member 120 rotates around the valve rod 28 as described above. The rotational speed of the opening degree display member 120 is lower than that of the cup type handle 100 because the number of teeth of the driven side internal gear 120c of the opening degree display member 120 is smaller than the number of teeth of the driving side internal gear 112b of the cup type handle 100. Because. Incidentally, the number of teeth of the external gear 122 is “8”.

保持部材124(図1および図5参照)は弁蓋26の六角形頭部260に動かないよう強く嵌め込まれる。保持部材124は、接触部140(図3、図4、および、図5参照)と歯車保持部142(図1参照)とを有する。図4、および、図5に示すとおり、接触部140は開度表示部材120の従動側内歯車120cに接触することにより開度表示部材120を回転自在に保持する。歯車保持部142には外歯車122の軸が回転自在に嵌まる。   The holding member 124 (see FIGS. 1 and 5) is firmly fitted to the hexagonal head 260 of the valve lid 26 so as not to move. The holding member 124 includes a contact portion 140 (see FIGS. 3, 4, and 5) and a gear holding portion 142 (see FIG. 1). As shown in FIGS. 4 and 5, the contact portion 140 contacts the driven side internal gear 120 c of the opening display member 120 to hold the opening display member 120 rotatably. The shaft of the external gear 122 is rotatably fitted to the gear holding portion 142.

次に、本実施形態にかかる開度表示機能つき開閉弁20の動作について説明する。図2で言えば時計回りの方向へカップ型ハンドル100を回転操作すると弁棒28が回転する。弁棒28が回転すると閉止部材24も回転する。このとき、閉止部材24は下降する。閉止部材24が十分に下降すると、閉止部材24の下部に設けた弁体240が閉止弁座228に接し、弁体240が閉止弁座228を塞ぐ。本実施形態の場合、この閉弁状態では、カップ型ハンドル100の覗き窓130から開度表示部材120表面の青く塗られた部分を覗くことが可能であることとする。   Next, the operation of the opening / closing valve 20 with an opening degree display function according to the present embodiment will be described. In FIG. 2, when the cup-type handle 100 is rotated in the clockwise direction, the valve stem 28 is rotated. When the valve rod 28 rotates, the closing member 24 also rotates. At this time, the closing member 24 is lowered. When the closing member 24 is sufficiently lowered, the valve body 240 provided at the lower portion of the closing member 24 comes into contact with the closing valve seat 228, and the valve body 240 closes the closing valve seat 228. In the case of this embodiment, in this valve-closed state, it is possible to look into the blue-painted portion of the surface of the opening display member 120 from the viewing window 130 of the cup-type handle 100.

次に、図2で言えば反時計回りの方向へカップ型ハンドル100を回転操作すると弁棒28が回転する。弁棒28が回転すると閉止部材24も回転する。このとき、閉止部材24は上昇する。閉止部材24の弁体240は閉止弁座228から離れていく。   Next, in FIG. 2, when the cup-type handle 100 is rotated in the counterclockwise direction, the valve stem 28 rotates. When the valve rod 28 rotates, the closing member 24 also rotates. At this time, the closing member 24 rises. The valve body 240 of the closing member 24 moves away from the closing valve seat 228.

このとき、カップ型ハンドル100が回転するので、外筒112の内周面の原動側内歯車112bも回転する。原動側内歯車112bが回転するので、これに噛合う外歯車122も回転する。外歯車122が回転するので、これに噛合う開度表示部材120の従動側内歯車120cも回転する。従動側内歯車120cが回転するので、開度表示部材120が弁棒28の周りを回る。回転方向はカップ型ハンドル100すなわち反時計回りである。ただし、上述した通り、開度表示部材120の回転速度はカップ型ハンドル100よりも低い。その結果、開度表示部材120のうち覗き窓130から視認できる領域が順次変わる。本実施形態の場合、上述した弁体240が閉止弁座228から十分離れた状態(開弁状態)では、カップ型ハンドル100の覗き窓130から開度表示部材120表面の赤く塗られた部分を覗くことが可能であることとする。   At this time, since the cup-type handle 100 rotates, the driving-side internal gear 112b on the inner peripheral surface of the outer cylinder 112 also rotates. Since the driving-side internal gear 112b rotates, the external gear 122 meshing with it also rotates. Since the external gear 122 rotates, the driven side internal gear 120c of the opening degree display member 120 that meshes with the external gear 122 also rotates. Since the driven-side internal gear 120 c rotates, the opening degree display member 120 rotates around the valve rod 28. The direction of rotation is the cup-type handle 100, that is, counterclockwise. However, as described above, the rotation speed of the opening degree display member 120 is lower than that of the cup-type handle 100. As a result, the region of the opening degree display member 120 that can be viewed from the viewing window 130 is sequentially changed. In the case of the present embodiment, when the above-described valve body 240 is sufficiently separated from the closing valve seat 228 (valve open state), the red painted portion of the surface of the opening display member 120 from the viewing window 130 of the cup-type handle 100 is removed. It is possible to peek.

以上のようにして、本実施形態にかかる開度表示機能つき開閉弁20は、側面すなわち弁棒28の回転軸に直交する方向から開閉状態を視認しようとするとき、様々な方向からそれが可能である。それが可能なのは、次の理由による。まず、等間隔に配置された5箇所の覗き窓130が設けられていることである。次に、開度表示部材120の回転速度がカップ型ハンドル100の回転速度よりわずかに低いことである。言い換えると、カップ型ハンドル100の回転時、カップ型ハンドル100に対する開度表示部材120の相対速度はごくわずかである。このことにより、5箇所もの覗き窓130を設けてもそれらのそれぞれから開度を示す情報を適切に視認できる。それが可能となっているのは、外歯車122が外筒112の原動側内歯車112bおよび開度表示部材120の従動側内歯車120cと噛合っているためである。   As described above, the opening / closing valve 20 with the opening degree display function according to the present embodiment can be viewed from various directions when the opening / closing state is visually confirmed from the side surface, that is, the direction orthogonal to the rotation axis of the valve rod 28. It is. This is possible for the following reasons. First, five observation windows 130 arranged at equal intervals are provided. Next, the rotational speed of the opening degree display member 120 is slightly lower than the rotational speed of the cup-type handle 100. In other words, when the cup handle 100 is rotated, the relative speed of the opening display member 120 with respect to the cup handle 100 is very small. Thus, even when five viewing windows 130 are provided, information indicating the opening degree can be appropriately visually recognized from each of them. This is because the external gear 122 meshes with the driving side internal gear 112b of the outer cylinder 112 and the driven side internal gear 120c of the opening degree display member 120.

開度表示部材120が筒部120aと斜面部120bとを有することも、側面から開度を容易に知ることができる理由の1つである。開度表示部材120が筒部120aと斜面部120bとを有するので、開度表示部材120が斜面部120bを有しており筒部120aを有していない場合に比べ、開度表示機能つき開閉弁20を見上げるような位置から開度を知ることが容易となっている。   The fact that the opening degree display member 120 has the cylindrical part 120a and the sloped part 120b is one of the reasons that the opening degree can be easily known from the side surface. Since the opening degree display member 120 has the cylinder part 120a and the slope part 120b, the opening degree display member 120 has the slope part 120b and has an opening degree display function compared with the case where the cylinder part 120a is not provided. It is easy to know the opening from a position where the valve 20 looks up.

<Second Embodiment>
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.
6 to 9 show an on-off valve 90 with an opening degree display function according to this embodiment. FIG. 6 is a longitudinal sectional view of the on-off valve 90 with an opening degree display function according to the present embodiment. FIG. 7 is a plan view of the on-off valve 90 with an opening degree display function according to the present embodiment. FIG. 8 is a cross-sectional view taken along the line AA of FIG. 9 is a cross-sectional view taken along line BB in FIG.

本実施形態にかかる開度表示機能つき開閉弁90は、第1実施形態にかかるカップ型ハンドル100と開度表示機構102とに代えて、カップ型ハンドル300と開度表示機構302とを設けたものである。   The on-off valve 90 with an opening degree display function according to the present embodiment is provided with a cup type handle 300 and an opening degree display mechanism 302 instead of the cup type handle 100 and the opening degree display mechanism 102 according to the first embodiment. Is.

図6および図8に示すとおり、カップ型ハンドル300は、内筒310と外筒312と頂壁314と固定部316とを有する。図8および図9に示すとおり、外筒312の内周面には、原動側内歯車312bが嵌め込まれている。図7に示すとおり、カップ型ハンドル300のうち外筒312から頂壁314にかけての箇所には、3箇所の覗き窓330が設けられる。内筒310と外筒312と頂壁314と固定部316とに関するその他の機能は、第1実施形態にかかる内筒110と外筒112と頂壁114と固定部116との機能と同様である。   As shown in FIGS. 6 and 8, the cup-type handle 300 includes an inner cylinder 310, an outer cylinder 312, a top wall 314, and a fixing portion 316. As shown in FIGS. 8 and 9, a driving-side internal gear 312 b is fitted on the inner peripheral surface of the outer cylinder 312. As shown in FIG. 7, three viewing windows 330 are provided in the cup handle 300 from the outer cylinder 312 to the top wall 314. Other functions related to the inner cylinder 310, the outer cylinder 312, the top wall 314, and the fixing portion 316 are the same as the functions of the inner cylinder 110, the outer cylinder 112, the top wall 114, and the fixing portion 116 according to the first embodiment. .

図6に示すように、カップ型ハンドル300内部には開度表示機構302が収容される。開度表示機構302は、開度表示部材320と、外歯車322(本実施形態における駆動歯車部である)と、保持部材324とを有している。開度表示部材320は、筒部320aと、斜面部320bと、従動側内歯車320cと、分解防止フック320dとを有する。筒部320aと斜面部320bとにおいて、「開」という文字が表示されている領域と「閉」という文字が表示されている領域とが交互に設けられている。これらの文字が開度を示す情報となっている。これらの領域は覗き窓330の外から視認できる。ちなみに、本実施形態の場合、図7に示すように、「開」という文字がある箇所同士がなす角度は2π/3ラジアン(120°)である。図示していないが、「閉」という文字がある箇所同士がなす角度も同様である。「開」という文字がある箇所とその隣の「閉」という文字がある箇所とがなす角度はπ/3ラジアン(60°)である。保持部材324は、接触部340(図6、図8、図9参照)と歯車保持部342(図6参照)と離脱防止フック344(図8、図9参照)とを有する。歯車保持部342は外歯車322の軸となる。離脱防止フック344は、図8に示すように、開度表示部材320の分解防止フック320dにひっかかる。これにより開度表示部材320が保持部材324から外れにくくなる。開度表示部材320と外歯車322と保持部材324とに関するその他の機能は、第1実施形態にかかる開度表示部材120と外歯車122と保持部材124との機能と同様である。   As shown in FIG. 6, an opening degree display mechanism 302 is accommodated in the cup-type handle 300. The opening display mechanism 302 includes an opening display member 320, an external gear 322 (which is a drive gear portion in the present embodiment), and a holding member 324. The opening degree display member 320 includes a cylindrical portion 320a, a slope portion 320b, a driven side internal gear 320c, and a disassembly prevention hook 320d. In the cylinder part 320a and the slope part 320b, the area | region where the character "open" is displayed and the area | region where the character "close" is displayed are provided alternately. These characters are information indicating the opening. These areas are visible from outside the viewing window 330. Incidentally, in the case of the present embodiment, as shown in FIG. 7, the angle formed by the portions having the letters “open” is 2π / 3 radians (120 °). Although not shown in the drawing, the angle formed by the portions having the characters “closed” is the same. The angle formed by the location where the character “open” is present and the location where the character “close” is adjacent is π / 3 radians (60 °). The holding member 324 includes a contact portion 340 (see FIGS. 6, 8, and 9), a gear holding portion 342 (see FIG. 6), and a separation preventing hook 344 (see FIGS. 8 and 9). The gear holding portion 342 serves as an axis of the external gear 322. As shown in FIG. 8, the separation prevention hook 344 catches on the disassembly prevention hook 320 d of the opening degree display member 320. This makes it difficult for the opening degree display member 320 to come off the holding member 324. Other functions regarding the opening degree display member 320, the external gear 322, and the holding member 324 are the same as the functions of the opening degree display member 120, the external gear 122, and the holding member 124 according to the first embodiment.

本実施形態にかかる開度表示機能つき開閉弁90の動作は第1実施形態にかかる開度表示機能つき開閉弁20の動作と同様なので、ここではその詳細は繰返さない。   Since the operation of the opening / closing valve 90 with an opening degree display function according to this embodiment is the same as the operation of the opening / closing valve 20 with an opening degree display function according to the first embodiment, the details thereof will not be repeated here.

以上のようにして、本実施形態にかかる開度表示機能つき開閉弁90は、第1実施形態にかかる開度表示機能つき開閉弁20と同様の理由により、側面から開閉状態を視認しようとするとき、様々な方向からそれが可能である。また、本実施形態にかかる開度表示機能つき開閉弁90は、開度表示部材320の分解防止フック320dと保持部材324の離脱防止フック344とが互いににひっかかっている。これにより開度表示部材320が保持部材324から外れにくくなっている。   As described above, the opening / closing valve 90 with the opening degree display function according to the present embodiment tries to visually recognize the opening / closing state from the side surface for the same reason as the opening / closing valve 20 with the opening degree display function according to the first embodiment. Sometimes it is possible from various directions. In the opening / closing valve 90 with an opening degree display function according to the present embodiment, the disassembly prevention hook 320d of the opening degree display member 320 and the separation prevention hook 344 of the holding member 324 are caught on each other. This makes it difficult for the opening degree display member 320 to be detached from the holding member 324.

Is.

カップ型ハンドル400は、内筒410(内筒410が本実施例における接続筒部である)と外筒412と頂壁414と固定部416とを有する。図10および図11に示すとおり、カップ型ハンドル400のうち外筒412から頂壁414にかけて、覗き窓430が3箇所設けられる。図10および図12に示すとおり、外筒412の内周面には、原動側内歯車412bが形成されている。さらに、図10に示すとおり、内筒410および弁棒28が固定部416を貫通するようになっている。図11に示すとおり、内筒410には接続側セレーション410a(接続側セレーション410aが本実施例における接続側凹凸部である)が設けられている。固定部416には、弁棒28の回転軸に沿って延びる固定側セレーション416a(固定側セレーション416aが本実施例における固定側凹凸部である)が設けられている。これにより、カップ型ハンドル400を回す際には接続側セレーション410aと固定側セレーション416aとが噛合う。それらが噛合うので内筒410と固定部416とが一体となって回転する。カップ型ハンドル400を引抜く場合には接続側セレーション410aは固定側セレーション416aに沿って動く。接続側セレーション410aが固定側セレーション416aに沿って動くので、カップ型ハンドル400を弁棒28から容易に取外すことができる。カップ型ハンドル400を弁棒28に嵌める際にも接続側セレーション410aは固定側セレーション416aに沿って動く。接続側セレーション410aが固定側セレーション416aに沿って動くので、覗き窓430の向きをかなり自由に設定できる。内筒410と外筒412と頂壁414と固定部416とに関するその他の機能は、第1実施形態にかかる内筒110と外筒112と頂壁114と固定部116との機能と同様である。   The cup-type handle 400 includes an inner cylinder 410 (the inner cylinder 410 is a connection cylinder portion in the present embodiment), an outer cylinder 412, a top wall 414, and a fixing portion 416. As shown in FIGS. 10 and 11, three viewing windows 430 are provided from the outer cylinder 412 to the top wall 414 in the cup-type handle 400. As shown in FIGS. 10 and 12, a driving-side internal gear 412 b is formed on the inner peripheral surface of the outer cylinder 412. Furthermore, as shown in FIG. 10, the inner cylinder 410 and the valve stem 28 penetrate the fixing portion 416. As shown in FIG. 11, the inner cylinder 410 is provided with a connection-side serration 410a (the connection-side serration 410a is the connection-side uneven portion in the present embodiment). The fixed portion 416 is provided with a fixed-side serration 416a extending along the rotation axis of the valve rod 28 (the fixed-side serration 416a is a fixed-side uneven portion in the present embodiment). Thereby, when turning the cup-type handle 400, the connection side serration 410a and the fixed side serration 416a are engaged with each other. Since they mesh with each other, the inner cylinder 410 and the fixing portion 416 rotate together. When the cup type handle 400 is pulled out, the connection side serration 410a moves along the fixed side serration 416a. Since the connection-side serration 410a moves along the fixed-side serration 416a, the cup-type handle 400 can be easily detached from the valve stem 28. The connection side serration 410a also moves along the fixed side serration 416a when the cup-type handle 400 is fitted to the valve stem 28. Since the connection-side serration 410a moves along the fixed-side serration 416a, the direction of the viewing window 430 can be set quite freely. Other functions related to the inner cylinder 410, the outer cylinder 412, the top wall 414, and the fixing portion 416 are the same as the functions of the inner cylinder 110, the outer cylinder 112, the top wall 114, and the fixing portion 116 according to the first embodiment. .

図10に示すように、カップ型ハンドル400内部には開度表示機構402が収容される。開度表示機構402は、開度表示部材420と、駆動歯車部422と、保持部材424とを有している。開度表示部材420の機能と保持部材424の機能とは、第1実施形態にかかる開度表示部材120、および、保持部材124と同様である。したがって、その詳細な説明は繰返さない。   As shown in FIG. 10, an opening degree display mechanism 402 is accommodated in the cup-type handle 400. The opening display mechanism 402 includes an opening display member 420, a drive gear portion 422, and a holding member 424. The function of the opening display member 420 and the function of the holding member 424 are the same as those of the opening display member 120 and the holding member 124 according to the first embodiment. Therefore, detailed description thereof will not be repeated.

本実施形態にかかる駆動歯車部422は、カップ型ハンドル400の原動側内歯車412bからトルクを受けて開度表示部材420の従動側内歯車420cへトルクを与える。これにより、駆動歯車部422は、カップ型ハンドル400よりも回転速度が低くなるよう開度表示部材420を駆動することとなる。図12に示すように、駆動歯車部422は、外筒噛合部450と、表示部材噛合部452と、回転軸部454とを有する。外筒噛合部450の歯が、外筒412の原動側内歯車412bに噛合う。表示部材噛合部452の歯が、開度表示部材420の従動側内歯車420cと噛合う。回転軸部454は、外筒噛合部450と表示部材噛合部452との回転軸となる。表示部材噛合部452の歯数は、外筒噛合部450の歯数より少ない。本実施形態の場合、開度表示部材420の従動側内歯車420cの歯数は「48」である。カップ型ハンドル400の原動側内歯車412bの歯数は「76」である。表示部材噛合部452の歯数は「12」である。外筒噛合部450の歯数「21」である。   The drive gear portion 422 according to the present embodiment receives torque from the driving-side internal gear 412 b of the cup-type handle 400 and applies torque to the driven-side internal gear 420 c of the opening display member 420. As a result, the drive gear unit 422 drives the opening degree display member 420 so that the rotational speed is lower than that of the cup-type handle 400. As shown in FIG. 12, the drive gear portion 422 has an outer cylinder engaging portion 450, a display member engaging portion 452, and a rotating shaft portion 454. The teeth of the outer cylinder meshing portion 450 mesh with the driving side internal gear 412b of the outer cylinder 412. The teeth of the display member meshing portion 452 mesh with the driven-side internal gear 420c of the opening degree display member 420. The rotation shaft portion 454 serves as a rotation shaft between the outer cylinder meshing portion 450 and the display member meshing portion 452. The number of teeth of the display member engagement portion 452 is smaller than the number of teeth of the outer tube engagement portion 450. In the present embodiment, the number of teeth of the driven side internal gear 420c of the opening degree display member 420 is “48”. The number of teeth of the driving-side internal gear 412b of the cup-type handle 400 is “76”. The number of teeth of the display member meshing portion 452 is “12”. The number of teeth of the outer tube engagement portion 450 is “21”.
