Description
本案は、開閉用ハンドルを有するバルブについての誤操作防止装置に関するものである。 The present invention relates to an erroneous operation preventing device for a valve having an opening / closing handle.
バルブは、化学プラント、石油精製所、パイプラインなどで、ライン切り替えや、流体の流量を制御する目的で広範囲に用いられている。 Valves are widely used in chemical plants, oil refineries, pipelines, etc. for the purpose of switching lines and controlling the flow rate of fluids.
バルブの目的は、ライン切り替えや、パイプ内の流体の流れを制御するためのものであり、不適切な時に開閉操作するとプラント全体、又は配管に重大な損傷を生じさせることになりかねない。バルブの開閉用ハンドルのロックに関する提案は数多くあり、鎖と南京錠（ 鎖をハンドルに通し南京錠で両端を固定する）といった 簡単なものから、バルブ専用の比較的高度なロックなどがあった（特許文献１）。しかし従来の誤操作防止装置は誤操作の防止機構にのみ重点が置かれ、作業者によるバルブの現状（開閉等の状況）の確認の容易さや、作業者による誤操作の防止については十分でない面があった。 The purpose of the valve is to switch the line and control the flow of fluid in the pipe. Opening and closing at an inappropriate time may cause serious damage to the entire plant or piping. There are many proposals for locking the valve opening and closing handles, from simple ones such as chains and padlocks (fixing both ends with a padlock through the chain) (Patent Documents) 1). However, the conventional erroneous operation prevention device focuses only on the mechanism for preventing erroneous operation, and there are not enough aspects to make it easy for the operator to check the current state of the valve (situation such as opening and closing) and to prevent erroneous operation by the operator. .
また、バルブに誤操作防止装置を取り付ける際に、バルブ本体に改造を加えてしまうとバルブの製造メーカーのバルブに対する保証が無効になる可能性があるため、誤操作防止装置を取り付けるための大幅な改造がバルブ側になされないことが必要であった。 In addition, if the valve body is modified when the valve is attached to the malfunction prevention device, the valve manufacturer's warranty for the valve may be invalidated. It was necessary not to be done on the valve side.
本案の目的は、バルブ側に誤操作防止装置を取り付けるための大幅な改造を必要とせず、かつ、作業者がバルブの現状を容易に確認可能であり、さらに作業者による誤操作を確実に防止し安全性を確保されるバルブの誤操作防止装置を提供する事である。 The purpose of this plan is that no major modification is required to attach an operation error prevention device to the valve side, the operator can easily check the current state of the valve, and it is safe to prevent erroneous operation by the operator. It is to provide a valve misoperation prevention device that can secure the performance.
本考案に係るバルブの誤操作防止装置は、網状カバーａにバルブ開閉ハンドルｄより小さい表示板ｂおよびバルブ開閉ハンドル装着用パッキングｃを取り付けたものである。 The device for preventing erroneous operation of a valve according to the present invention is such that a display plate b smaller than a valve opening / closing handle d and a packing c for mounting a valve opening / closing handle are attached to a mesh cover a.
本考案における網状カバーａは、バルブ開閉ハンドルｄを覆うことができるものであれば、その形状は特に制限されない。 The shape of the mesh cover a in the present invention is not particularly limited as long as it can cover the valve opening / closing handle d.
本考案におけるバルブ開閉ハンドルｄより小さい表示板ｂは、例えば、網状カバーａに針金等を用いて取り付けられ、その大きさはバルブ開閉ハンドルｄよりも小さいものであれば、その形状は特に制限されない。 The display plate b smaller than the valve opening / closing handle d in the present invention is attached to the mesh cover a using a wire or the like, and the shape thereof is not particularly limited as long as the size is smaller than the valve opening / closing handle d. .
本考案におけるバルブ開閉ハンドル装着用パッキングｃは、例えば、ゴム等の柔軟性を持つ物質からなり、網状カバーａに針金等を用いて取り付けられ、本考案の誤操作防止装置の装着対象であるバルブ開閉ハンドルｄに装着可能な開口部があればよい。 The packing c for mounting the valve opening / closing handle in the present invention is made of a material having flexibility such as rubber, and is attached to the mesh cover a using a wire etc. There may be an opening that can be attached to the handle d.
本考案のバルブの誤操作防止装置は、網状カバーａに取り付けられたバルブ開閉ハンドル装着用パッキングｃに設けられた開口部を用いてバルブ開閉ハンドルｄに装着する。
本考案のバルブの誤操作防止装置の装着後、バルブ開閉ハンドルｄの作業者による誤操作を確実に防止される。 さらにダイヤフラム弁では、バルブが開の場合に図６に示すとおり弁棒の先端が突出するため、バルブ開閉用ハンドルｄの中央部にある弁棒ｅの状態を金網越しに視認することにより、バルブの開閉状況も確認することもできる。
The device for preventing erroneous operation of the valve according to the present invention is mounted on the valve opening / closing handle d using an opening provided in a valve opening / closing handle mounting packing c attached to the mesh cover a.
After installation of the valve malfunction prevention device of the present invention, erroneous operation by the operator of the valve opening / closing handle d is reliably prevented. Further, in the diaphragm valve, when the valve is open, the tip of the valve stem protrudes as shown in FIG. 6, so that the state of the valve stem e at the center of the valve opening / closing handle d can be visually confirmed through a wire mesh. You can also check the opening and closing status.
本考案のバルブの誤操作防止装置は、バルブ側に誤操作防止装置を取り付けるために大幅な改造を必要とせず、かつ、作業者による誤操作を確実に防止し、安全性を確保する事が出来、さらに作業者がバルブの開閉状態を容易に確認可能である。 The device for preventing erroneous operation of the valve according to the present invention does not require any major modification in order to install the device for preventing erroneous operation on the valve side, can reliably prevent erroneous operation by an operator, and can ensure safety. The operator can easily check the open / closed state of the valve.
本考案に係るバルブの誤操作防止装置は、バルブ開閉ハンドルｄより小さい表示板ｂとバルブ開閉ハンドル装着用パッキングｃが取りつけられた網状カバーａをバルブ開閉ハンドル装着用パッキングｃに設けられた開口部を用いてバルブ開閉ハンドルｄに装着する。 The device for preventing erroneous operation of the valve according to the present invention has a display plate b smaller than the valve opening / closing handle d and a mesh cover a to which the valve opening / closing handle mounting packing c is attached provided with an opening provided in the valve opening / closing handle mounting packing c. Used to attach to the valve opening / closing handle d.
以下、添付図に従って、一実施例を説明する。 本考案に係るバルブの誤操作防止装置は、例えば、網状カバーａにバルブ開閉ハンドルｄより小さい表示板ｂとバルブ開閉ハンドル装着用パッキングｃが取りつけられた本考案のバルブの誤操作防止装置をバルブ開閉ハンドル装着用パッキングｃに設けられた開口部を用いてバルブ開閉ハンドルｄに装着することにより作業者による誤操作を確実に防止する。 An embodiment will be described below with reference to the accompanying drawings. The device for preventing erroneous operation of the valve according to the present invention includes, for example, the device for preventing erroneous operation of the valve according to the present invention in which the display cover b smaller than the valve opening / closing handle d and the packing c for mounting the valve opening / closing handle are attached to the mesh cover a. By attaching to the valve opening / closing handle d using the opening provided in the mounting packing c, erroneous operation by the operator is surely prevented.
