Background

At present, in some factories, due to design and installation reasons, pipelines vibrate due to equipment operation, and therefore valves on the pipelines are driven to vibrate. Because the valve operating handle does not have a locking device, the valve operating handle usually rotates along with the vibration, so that the position of the valve changes, the normal operation of equipment is influenced, and meanwhile, noise pollution is also generated. At present, the valve operating handle can only be fixed by the friction force of the valve operating handle or tied by a cloth belt, so that the valve operating handle is unreliable and unattractive.

The locking device special for the valve operating handle aims to fix the position of the valve operating handle, lock the opening degree of a valve, prevent the opening degree of the valve from being changed artificially and ensure the normal operation of equipment.

In order to achieve the above object, the present invention is achieved by the following technical solutions:

the device for preventing the valve from being opened or closed by mistake due to vibration comprises a locking device, wherein the locking device is formed by connecting a locking device cylindrical structure and a locking device disc structure.

The locking device is made of stainless steel.

The locking device is characterized in that the cylindrical structure of the locking device is a cylinder structure, and a through middle hole is formed in the cylinder; the cylinder of the locking device cylinder structure is provided with a threaded hole.

The size of the middle hole is larger than that of the valve operating shaft, and the middle hole penetrates through the center.

The threaded holes are formed in the vertical direction of a cylinder of the locking device cylindrical structure, and three symmetrical threaded holes are formed in the vertical direction.

The locking device disc structure is provided with a through hole.

The locking device disk structure is the same size as the rear valve body.

The through holes are symmetrical and are totally four.

The position and the size of the opening of the through hole are the same as those of the original screw hole in the rear valve body.

A method for installing a device for preventing a valve from being opened or closed by mistake due to vibration comprises the following steps:

step 1, disassembling a valve operating handle;

step 2, disassembling a fixed valve screw on the valve body;

step 3, the locking device penetrates through the valve operating shaft, and the through hole in the disc structure of the locking device is aligned with the original screw hole in the valve body;

step 4, screwing down the fixed valve screw, and fixedly connecting the locking device to the valve body;

step 5, installing a valve operating handle;

step 6, adjusting the opening of the valve;

and 7, screwing the locking screw.

The invention has the advantages and beneficial effects that:

1. the device has the characteristics of simple design, attractive appearance and practical function.

2. The device does not change the structure of the valve. The operation shaft of the valve does not need to be milled, drilled and ground, so that the adverse effect on the torsion strength of the operation shaft of the valve is avoided.

3. The device can lock the valve at any opening degree. The noise generated by shaking of the valve operating handle can be eliminated, and the harm of shaking of the valve operating handle to the sealing of the valve shaft of the valve is reduced.
