本考案は、ハンドルの脱落防止装置を有しハン
ドルの回転角度が一定の範囲にある場合にのみハ
ンドルをバルブから着脱することができるバルブ
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a valve having a device for preventing the handle from falling off and allowing the handle to be attached to and removed from the valve only when the rotation angle of the handle is within a certain range.
ボールバルブ、コツクバルブ等は、化学工場そ
の他流体を取り扱うプラント類に多く用いられて
いる。これらのバルブ類は一般にハンドル部分が
着脱可能であつて、バルブの開閉操作を行なう場
合にバルブに取り付けてバルブの開閉操作を行な
う。 Ball valves, Kotsuk valves, etc. are often used in chemical factories and other plants that handle fluids. These valves generally have a removable handle, and are attached to the valve to open and close the valve.
この場合、バルブの取り付け位置によつては、
バルブの開閉の確認が困難である場合が多く、バ
ルブの半開等の誤操作の原因となつていた。 In this case, depending on the installation position of the valve,
It is often difficult to confirm whether the valve is open or closed, leading to incorrect operation such as opening the valve halfway.
本考案者は、かかる問題点を解決し、開閉操作
を確実に行うことができるバルブを提供すること
を目的として鋭意努力を重ねた結果本考案に到達
したものである。 The inventor of the present invention has arrived at the present invention as a result of diligent efforts aimed at solving these problems and providing a valve that can be opened and closed reliably.

ルブによつて達せられる。 The object of the present invention is to provide a valve having a detachable operating handle, in which a circular part of the circular part is cut out to prevent the handle from falling off, and the center thereof is within the rotating plane of the operating handle. This is achieved by a valve that is installed so as to coincide with the rotation axis of the operating handle and to pass through a through hole provided in the operating handle.

ハンドルに設けられた貫通孔である。 In FIG. 1, 1 is a valve, 2 is an operating handle, 3 is a wheel to prevent the handle from falling off, and 4 is an attachment for the handle to prevent the handle from falling off. Reference numeral 5 denotes a through hole provided in the handle so that the drop-off prevention ring 3 passes through and allows the handle to rotate freely.

り付けてもよい。 The drop-off prevention ring 3 has a circular arc shape with a portion of the circle cut out, and is attached so that the cutout portion is located at a position that corresponds to the rotational position of the handle at which the handle is desired to be attached or detached. For example, if you install the notch so that it matches the location where the handle would be when the valve is fully closed, the handle can only be removed from the valve when the valve is fully closed, which could result in accidental operation. can be prevented. The width of the notch only needs to be sufficient for attaching and detaching the handle, and if it is too wide, it is not preferable because the operation becomes inaccurate. It is preferable that the fall prevention ring 3 is made of mild steel, stainless steel, or other suitable metal with a diameter of about 3 to 6 mm. Also, the diameter of the fall prevention ring 3 varies depending on the valve.
Approximately 20 to 80 mm is appropriate. Attachment 4 is 2
It is made of a metal plate made of mild steel or the like and has a thickness of about 5 mm, and is attached to the flange of the valve 1. The fall-off prevention ring 3 is attached to the attachment tool 4 by welding, screwing, or the like. Attachment 4 is handle 2
It is preferable that the width is narrow so as not to interfere with the operation of the valve 1. In particular, one end of the stopper ring 3 may be bent at a substantially right angle and attached to the valve 1 without using the attachment 4.
貫通孔５は、ハンドル２が脱落防止輪３上を円
滑に摺動できるように設けられる。 The through hole 5 is provided so that the handle 2 can smoothly slide on the fall prevention ring 3.
本考案に係るバルブでは、ハンドルを正しい操

工場等の操業の安全を図る上で極めて有益であ
る。 In the valve according to the present invention, since the handle cannot be removed unless it is set in the correct operating position, erroneous operation can be prevented, and this is extremely useful for ensuring the safety of operations at chemical plants and the like.
