【考案の詳細な説明】
この考案は、埋設バルブたとえば水道・ガス等
の埋設バルブの弁きよう用蓋体に関するもので、
とくにバルブの開度と口径を表示できるように改
良したものである。[Detailed description of the invention] This invention relates to a valve cover for a buried valve, such as a buried valve for water, gas, etc.
In particular, it has been improved to display the opening degree and diameter of the valve.
バルブの開度を示すものについては、既に多数
の考案があるが、その一例として実公昭32−767
号公報に記載されたものであるが、これは弁棒３
に付随して回転する指針１０を設け、この指針１
０によつて弁棒３の１回転以下の回転度を示し、
更に指針１０に連動する回転表示板５によつて、
１回転以上の回転数を示すものである。 There are already many ideas for indicating the opening degree of a valve, but one example is
This is the valve stem 3, which is described in the No.
A pointer 10 is provided which rotates along with the pointer 1.
0 indicates the degree of rotation of the valve stem 3 of one rotation or less,
Furthermore, by the rotating display plate 5 linked to the pointer 10,
This indicates the number of revolutions of one revolution or more.
しかし、この装置を埋設バルブに用いる場合、
表示機構が弁棒と連動するため、構成が複雑とな
るほか土砂等が回転部分にカミ込んで回転不能と
なる虞れがあり、この結果バルブの開閉までが不
能となることがある。しかも、この故障は埋設バ
ルブのように地中にあるものにとつては、極めて
発生しやすい事故である。また故障修理は埋設バ
ルブを堀り出さねばできない場合も生ずる。さら
に表示機構が弁きようの深いところにあるため、
暗くて見にくく読み違いの原因ともある。 However, when using this device for buried valves,
Since the display mechanism is linked to the valve stem, the structure is complicated and there is a risk that dirt or the like may get stuck in the rotating parts, making them unable to rotate.As a result, the valve may not be able to open or close. Moreover, this failure is extremely likely to occur for items that are underground, such as buried valves. In addition, there are cases where the buried valve cannot be repaired unless the buried valve is excavated. Furthermore, since the display mechanism is located deep inside the valve canal,
It is dark and difficult to see, which can lead to misreading.
一方埋設バルブ用表示器によつて最小限必要な
ことは、現在このバルブはどの位開いているかと
いうことである。そして日頃バルブを扱つている
者には、バルブの開度は弁棒の回わし具合によつ
て分るので、必ずしも指針は弁棒に係合させる必
要はなく、弁棒を回わしはじめたとき、既にどの
位開口しているかが知られていれば、その以後の
開度は自ずと分る。また開度以外に、該バルブの
口径が分れば便利である。 On the other hand, the bare minimum required by an indicator for a buried valve is how open the valve is currently. For those who work with valves on a daily basis, the degree of opening of the valve can be determined by the degree to which the valve stem is turned, so the pointer does not necessarily need to engage the valve stem, but when the valve stem starts turning. , if you already know how much it has opened, you can automatically know how much it will open after that. In addition to the opening degree, it is convenient if the diameter of the valve is known.
この考案は上記の事情を考慮して提案したもの
で、バルブにとつて最小限必要である該バルブの
現在の開度と口径を簡単に表示する表示器を蓋体
の裏面に設けることによつて、見やすく且つ土砂
に埋もれないように工夫した表示器付の弁きよう
用蓋体である。 This idea was proposed in consideration of the above-mentioned circumstances, by providing an indicator on the back of the lid that easily displays the current opening degree and diameter of the valve, which are the minimum requirements for the valve. This is a valve cover with an indicator that is easy to see and does not get buried in dirt.

開き方向を示す。 An embodiment will be described below based on the drawings. A thumbscrew is screwed into the center of the back surface of the lid 3 of the valve cover 2 as a support shaft 4, and two large and small rotating discs 5 and 6 are rotatably attached to this. . And the larger turntable 5
A scale indicating the diameter of the valve is displayed on the outer periphery of the valve. Since the diameter of the valve in this example is 50 to 400, this value is used as the scale. A scale indicating the opening degree of the valve is displayed on the back surface of the lid body 3 along the outer periphery of the rotary disk 5. The scale of the lid body 3 may be displayed directly on the back surface or may be displayed on a plate prepared. The scale is divided into 45 equal parts from 0 indicating closed to fully open. This is because the valve closes at 45 rotations, and the degree of opening of the valve is approximately proportional to the number of rotations of the valve stem, so the degree of opening can be indicated by the number of rotations. In addition, an arrow is marked as an indicator 7 on the smaller rotary disk 6, and letters ``open left'' on one side 61 and ``open right'' on the back 62 indicate the opening direction of the valve.

で表示を進めてゆく。 Using this, for example, left opening, caliber 100,
To indicate that the opening degree is 10, loosen the spindle 4 and turn the larger rotary disk 5 so that its 100 scale matches the 10 scale on the back of the lid body 3, as shown in Figure 3. After that, turn the small turntable 6 and set the indicator 7 to the 100, 10 scale. Note that, prior to this, the small rotary disk 6 is set so that the surface 61 on which the left opening character is displayed is the front side. Each time a valve is moved, the operator advances the display in the manner described above.
この考案は以上説明したように、表示器を蓋体
の裏面に設けたため、見やすく且つこの表示器は
作業者が操作して表示を進めるもので、バルブの
開閉に連動しないので、構造が極めて簡単で安価
に提供でき、しかもバルブにとつて最小限必要で
ある現在の開度と口径を表示できる。そして取付
場所を蓋体の裏面としたので、土砂をカミ込んで
操作不能となる虞れも全くないものである。 As explained above, this device has a display on the back of the lid, making it easy to see, and since the display is operated by the operator and is not linked to the opening and closing of the valve, the structure is extremely simple. It can be provided at low cost, and can display the current opening degree and diameter, which are the minimum required for the valve. Since the mounting location is on the back side of the lid, there is no risk of dirt getting in there and making it inoperable.
