記振動などで切れ易くなる等の欠点があつた。 Valves installed in each pipeline in a factory are often kept open under normal conditions.
In the case of small valves, vibrations of attached equipment may cause the operating handle to rotate naturally and become closed, obstructing or stopping the flow. Conventionally, a method to prevent this has been to tie the operating handle to the valve body with wire, etc., but the wire must be cut each time the valve needs to be closed, and the wire deteriorates. However, there were drawbacks such as the tendency to break due to the vibrations and the like.

テムの長さに略等しく構成したものである。 On the other hand, the operating handle fixing device of this invention is extremely easy to attach and detach, and can be reliably maintained in the open state. That is, the valve operating handle fixing device of the present invention is made by bending a rectangular metal plate into a split cylinder shape with an inner diameter that fits the required valve stem with its two corresponding sides facing each other, and engaging the plate at the two sides. They form an edge and are removably connected to each other, and the height of this cylinder is matched to the length of the valve stem located between the lower surface of the valve operating handle and the upper surface of the valve body when the valve is released as required. Consisting of: To explain this with reference to the drawings, FIG. 1 shows a rectangular metal plate 1 such as an aluminum plate, whose two corresponding sides are bent to interlocking edges 2, 2, respectively, so that they can be engaged and detached, and whose inner diameter d is The required size of the valve to cover the circumferential surface of the valve stem and the cylinder height h are approximately equal to the length of the valve stem in the open state.

を介してバルブ主体適所に接続しておくとよい。 To use the fixing device of this invention, as shown in Figure 2, the engagement lines 2, 2 are removed and the valve stem is inserted from the side in the open state, that is, with the operating handle raised to the predetermined position. fitted,
It is only necessary to engage the interlocking edges 2, 2. As a result, the operating handle is prevented from descending, and the open state is always maintained. For this purpose, the overall shape is not necessarily limited to a cylinder, but may be a polygonal cylinder.
In order to prevent powder from being generated when the valve is removed from the valve stem in order to close the valve, it is preferable to connect it to the valve main body at an appropriate position, for example, via a link or the like.

ン３を嵌挿するようにしたものである。 FIG. 3 shows another modification of FIG. 1. That is, the two sides of the rectangular metal plate 1 are formed into cylindrical wires 2', 2' into which the pin 3 is inserted.

の利点がある。 As mentioned above, this invention is a cylindrical body that simply fits into the valve stem by utilizing the elasticity of the metal plate, and although it has an extremely simple structure, it reliably prevents the rotation of the operating handle. Moreover, it is easy to attach and detach, and while it is attached, it can be confirmed at a glance that the valve is in the open state, and since the two sides are engaged, at first glance it looks like a normal cylinder with an open cover. There are many advantages such as there is no risk of it coming off, and since it is cylindrical, it also helps protect the threads of the valve stem.
