Abstract

PROBLEM TO BE SOLVED: To provide a ball valve which enables manual and simple performance of an operation of the ball valve used for a variety of purposes such as the opening/closing and switching of a channel, and on which a general tool is hooked when a manual handle operation can be hardly performed because a handle is fixed due to adhesion of foreign matter and the like, though the round handle dispensing with a rotational space is used.SOLUTION: A wrench hook 3 is formed in a central boss part 2 of a round handle 1. In regard to the round handle that can hardly be subjected to a rotational operation due to fixation, a wrench is hooked on the formed rench hook 3, and the rotational operation can be performed by releasing the fixation by a strong rotational force exerted by the wrench.

Description

本発明は、止水栓や切換えバルブ装置等に用いられるボールバルブの回動に用いるハンドル、特に丸型ハンドルに関するものである。   The present invention relates to a handle, particularly a round handle, used for turning a ball valve used in a water stopcock, a switching valve device, or the like.

ボールバルブを用いたバルブ装置には様々な形態のものが存在するが、所定の軸線回りで回転可能に設けられると共に、軸線と直交する方向に貫通した連通路が形成された球状の弁体と、その弁体を収容する弁体収容室が形成されると共に、その弁体収容室を挟んで少なくとも二つの通水路が形成されたハウジングによって構成されている。   There are various types of valve devices using a ball valve, and a spherical valve body provided with a communication passage penetrating in a direction perpendicular to the axis line and provided so as to be rotatable around a predetermined axis line. A valve body housing chamber for housing the valve body is formed, and at least two water passages are formed across the valve body housing chamber.

ボールバルブは流路の開閉や切換え等、多様な用途に用いられ、その回動操作については例えば特許文献1に記載されているようにハンドルやアクチュエータ等によっても行われるが、手動で簡易に行うことができ、回動スペースも不要なところから、丸型ハンドルが用いられることが多い。   The ball valve is used for various applications such as opening / closing and switching of the flow path, and the rotation operation is also performed by a handle, an actuator, or the like as described in Patent Document 1, for example. However, a round handle is often used because it does not require a rotating space.

一方、手動で円滑な操作では強力な締着が期待できない場合には、特許文献2に記載されるように締付け部をレンチ掛けに形成し、レンチによる強力な回動力を利用する手段が用いられてきている。 On the other hand, when strong tightening cannot be expected by a smooth operation manually, a means for forming a tightening portion on a wrench and using a strong turning force by a wrench is used as described in Patent Document 2. It is coming.

ボールバルブは、給水管の途中の止水栓として設置され、長期間開閉操作が行われない場合、球状の弁体やボールシートに錆び等の異物が付着し、それが固着して手動でのハンドル操作が困難になる場合があり、こうした場合、工具類をハンドルに掛ける等による強力な回動力を用いて固着を解いて操作するが、丸型ハンドルはその形態上、一般の工具を掛けることが困難であった。   The ball valve is installed as a stop cock in the middle of the water supply pipe.If the valve is not opened and closed for a long period of time, foreign matter such as rust adheres to the spherical valve body or ball seat, and it adheres to it manually. Handle operation may be difficult. In such cases, the handle is released using a powerful turning force such as hanging tools on the handle, etc., but the round handle requires a general tool. It was difficult.

従って、これまでは、先端に、ハンドルの形状に合わせてハンドルのボスと操作輪の間に挿入される爪を設定した特別な開栓器を用いて固着を開放して操作する方法が採られ、専用の開栓器を用意しなければならないという問題があった   Therefore, until now, a method has been adopted in which a sticker is opened and operated using a special opener with a claw inserted between the boss of the handle and the operation wheel in accordance with the shape of the handle at the tip. There was a problem of having to prepare a dedicated opener

また、丸型ハンドルを用いた止水栓は、蝶型ハンドルやレバー型ハンドルのように90度開閉操作でハンドルの向きが変わることによる開閉状態の判別が困難なため、表示板等を使用して開閉状態の明確化を行っているが、部品点数が増加しコストアップの要因となる問題もあった。   In addition, the faucet using a round handle uses a display board or the like because it is difficult to determine the open / closed state due to the change in the direction of the handle by 90 ° opening / closing operation like a butterfly handle or lever handle. Although the open / closed state has been clarified, there has been a problem that the number of parts increases and causes an increase in cost.

本発明は上記した課題に対応しようとするものであり、丸型ハンドルの中心ボス部にレンチ掛けを形成し、固着により回動操作が困難となった丸型ハンドルをレンチによる強力な回動力により固着を解き回動操作を行えるようにした。   The present invention is intended to address the above-mentioned problems. A wrench hook is formed on the center boss of the round handle, and the round handle, which is difficult to rotate by fixing, is turned by a powerful turning force with a wrench. The sticking is released and the rotation operation can be performed.

また、ハンドル表面の所定部位に、流水方向を示す表示記号を表示するようにして、ボールバルブの開閉状態を容易に判別できるようにした。   In addition, a display symbol indicating the flowing water direction is displayed at a predetermined portion on the handle surface so that the open / close state of the ball valve can be easily determined.

上記のように、固着により回動操作が困難となった丸型ハンドルについて、丸型ハンドルの中心ボス部に形成したレンチ掛けを利用して市販のレンチを掛架して直ちに強力な回動力により固着を解き回動操作が行え、特別な開栓器を用意する無駄を省くことができたものである。   As described above, for a round handle that has become difficult to rotate due to sticking, a commercially available wrench is hung using a wrench hook formed on the center boss of the round handle, and immediately with strong turning force. It was possible to remove the sticking and perform the rotation operation, and to eliminate the waste of preparing a special opener.

更に、ハンドル表面の所定部位に表示するようにした流水方向を示す表示記号によってボールバルブの開閉状態が容易に判別でき、ボール弁体の90度回動による送水状態が確実に把握できるようになった。   Furthermore, the open / closed state of the ball valve can be easily discriminated by the display symbol indicating the direction of water flow displayed on a predetermined part of the handle surface, and the water supply state due to the 90 degree rotation of the ball valve body can be surely grasped. It was.

以下、図面を参照して本発明の実施の形態について詳細に説明すると、1は丸型ハンドルの本体で、止水栓のボール弁体5を回動操作する栓棒41の上端を収嵌する中心ボス部2と、これから放射状に伸びるスポークアーム21によって支持される操作輪22から成り、操作輪22を回動して栓棒41を回動操作するようになっている。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a main body of a round handle, which fits an upper end of a stopper rod 41 that rotates a ball valve body 5 of a stop cock. The operation wheel 22 is supported by a central boss portion 2 and a spoke arm 21 extending radially from the center boss portion 2. The operation wheel 22 is rotated to rotate the plug bar 41.

4は止水栓本体で、その弁室42に、中腹に貫通通水孔51が穿設され、頂部に貫通通水孔の貫通方向と直交する嵌合溝52が栓棒41の下端と嵌合するボール弁体5を内蔵し、弁室42の両側には1次側通水口4aと2次側通水口4bが開口し、これを介して流水路1次側の配管継手部11と2次側の配管継手部12にそれぞれ連通するようになっている。 Reference numeral 4 denotes a water stopcock body. A through water passage hole 51 is formed in the valve chamber 42 in the middle, and a fitting groove 52 perpendicular to the penetration direction of the through water passage hole is fitted to the lower end of the stopper rod 41. The ball valve body 5 to be combined is housed, and the primary side water inlet 4a and the secondary side water inlet 4b are opened on both sides of the valve chamber 42, through which the pipe joint portions 11 and 2 on the primary side of the water flow channel are opened. It communicates with the pipe joint portion 12 on the next side.

貫通通水孔51は、常時は弁室42の1次側通水口4aと2次側通水口4bに沿って開口し、その開口部5aと5bが図1の(b)に示されるように1次側通水口4aと2次側通水口4bとそれぞれ接合して1次側の配管継手部から2次側の配管継手部に連通する流路を形成している。   The through water passage 51 is normally opened along the primary water passage 4a and the secondary water passage 4b of the valve chamber 42, and the openings 5a and 5b are as shown in FIG. The primary side water inlet 4a and the secondary side water inlet 4b are joined to form a flow path that communicates from the primary side pipe joint to the secondary side pipe joint.

丸型ハンドル1が90度回動されると、ボール弁体5は90度回動されて貫通通水孔51か方向を変えると共に、図1の(c)に示されるように1次側通水口4aと2次側通水口4bがそれぞれ1次側の配管継手部から2次側の配管継手部に連通する流路が閉鎖されて水流が止められるものである。 When the round handle 1 is rotated 90 degrees, the ball valve body 5 is rotated 90 degrees to change the direction of the through water passage hole 51 and the primary side passage as shown in FIG. The water flow is stopped by closing the flow paths where the water port 4a and the secondary water flow port 4b communicate from the primary side pipe joint part to the secondary side pipe joint part, respectively.

本発明の実施形態としての実施例1を、図面を参照して説明する。
図2は中心ボス部2の上面にレンチ掛け3を突設した実施例を示すもので、レンチ掛け3の形態は止水栓本体の設定環境により、用意される回動レンチの形態に対応して図6の(ア)、(イ)、(ウ)の各形態が選定されることになる。
Example 1 as an embodiment of the present invention will be described with reference to the drawings.
FIG. 2 shows an embodiment in which a wrench hook 3 is projected from the upper surface of the central boss portion 2. The form of the wrench hook 3 corresponds to the form of a rotating wrench prepared depending on the setting environment of the water stopcock body. Thus, the forms (a), (b), and (c) in FIG. 6 are selected.

また、止水栓本体の形態により、丸型ハンドル1のレンチ掛け3の中心部の肉抜きを行って、材料の節約と重量軽減を図るようにする。栓棒41との係合は肉抜き部31の底部に栓棒41頂部の収嵌スペース32に抜けるビス穴33を開けて栓棒41の頂部をビス止めするが、肉抜き部31の上部は開放されており雨水等が溜まるので水抜き孔を設けるか、ビス穴33の側部に水抜き溝34を形成するようにする。 Further, the central portion of the wrench hook 3 of the round handle 1 is removed according to the shape of the water stopcock main body so as to save material and reduce weight. In the engagement with the plug bar 41, a screw hole 33 extending into the fitting space 32 at the top of the plug bar 41 is opened at the bottom of the thinned part 31 to screw the top of the plug bar 41. Since it is open and rainwater or the like accumulates, a drain hole is provided or a drain groove 34 is formed on the side of the screw hole 33.

更に、丸型ハンドルには、図4に示すように、従来から閉口回動方向を示す矢印とS、開口回動方向を示す矢印とOの表示がなされてきたが、本発明のように90度の回動によって止水栓の開閉が行われる場合、この表示だけではボールバルブの開閉状態が容易に判別できない問題がある。 Further, as shown in FIG. 4, the round handle has conventionally been displayed with an arrow and S indicating the closing rotation direction, and an arrow and O indicating the opening rotation direction. When the stop cock is opened and closed by rotating the degree, there is a problem that the open / closed state of the ball valve cannot be easily discriminated only by this display.

本発明は上記の問題に対応して、ハンドル表面の所定部位に表示するようにした流水方向を示す表示記号35によってボールバルブの開閉状態が容易に判別でき、ボール弁体の90度回動による送水状態が確実に把握できるようにしている。 In the present invention, in response to the above problem, the open / close state of the ball valve can be easily discriminated by the display symbol 35 indicating the direction of water flow displayed on a predetermined part of the handle surface, and the ball valve body is rotated 90 degrees. It ensures that the water supply status can be ascertained.

図9はハンドルのスポークアーム21から操作輪22の表面にかけて、或いは操作輪22の表面に流水方向を示す表示記号35の実施例を示すもので、レンチ掛け3の形態や止水栓本体の設定環境により、図9の(ア)、(イ)、(ウ)の各形態、或いは図7に示される形態が選定されることになる。 FIG. 9 shows an embodiment of a display symbol 35 indicating the direction of water flow from the handle's spoke arm 21 to the surface of the operation wheel 22 or on the surface of the operation wheel 22. Depending on the environment, the forms (a), (b), (c) in FIG. 9 or the form shown in FIG. 7 is selected.

図7、8は、回動固着の強度が増し、レンチによる回動支点を大きくとる必要がある場合に対応する実施例を示すもので、上述の構成に加えてハンドル操作輪22の所定部位に、レンチグリップGの延長支点が掛架する支柱36を着脱可能に設定するようにした。 FIGS. 7 and 8 show an embodiment corresponding to the case where the strength of the rotation fixing is increased and the rotation fulcrum by the wrench needs to be set large. In addition to the above-described configuration, FIG. The support column 36 on which the extension fulcrum of the wrench grip G is hung is set to be detachable.

支柱36は、図7に示すように操作輪22のスポークアーム21によって支持される部位に螺合孔又は嵌合孔を設けて着合するようにし、常時は邪魔に成らぬように取り外しておくものである。丸型ハンドルの固着開放を行う場合には、図8に示されるようにレンチボックスをレンチ掛け3に掛け、レンチグリップGの延長支点を支柱36に掛架することにより安定した支持点を得ることができ、より安定した回動力を丸型ハンドルに加えることができる。 As shown in FIG. 7, the support column 36 is fitted with a screw hole or a fitting hole at a portion supported by the spoke arm 21 of the operation wheel 22, and is always removed so as not to get in the way. Is. When the round handle is fixed and released, a stable support point is obtained by hanging the wrench box on the wrench hook 3 and hanging the extension fulcrum of the wrench grip G on the column 36 as shown in FIG. And more stable turning force can be applied to the round handle.

実施例2は、中心ボス部2の下端基幹部をレンチ掛け3に形成するようにしたものであり、図3に示される通りハンドル表面に余計な突出がなく、栓棒41がそのままレンチ掛け3に嵌合されることになるので、材料の節約と重量軽減の面では有利であるが、側方からレンチを掛架しなければならないため、強力で安定した回動力が得難い問題がある。   In the second embodiment, the bottom boss portion of the central boss portion 2 is formed on the wrench hook 3, and as shown in FIG. 3, there is no extra protrusion on the handle surface, and the plug bar 41 remains as it is. However, there is a problem that it is difficult to obtain a strong and stable rotational force because a wrench must be hung from the side.

本発明に係る水道用ボールバルブ操作用丸型ハンドルは、従来から、流路の開閉や切換え等、多様な用途に用いられてきたボールバルブ操作について、手動で簡易に行うことができ、回動スペースも不要な丸型ハンドルの適用の難点であった回動固着の開放を容易にしたので、水道用器具の合理的活用を押し進めることができ、水道施設産業上に高度の利用価値を有するものである。   The circular handle for water ball valve operation according to the present invention can be easily and manually operated for ball valve operation that has been used for various applications such as opening / closing and switching of flow paths. Since it has facilitated the opening of the rotation sticking, which was a difficulty in applying round handles that do not require space, it can push the rational use of water supply equipment and has a high utility value in the water supply industry It is.
