Description

Telescopic hidden handle for high-pressure ball valve

Technical Field

The utility model relates to the technical field of high-pressure ball valves, in particular to a telescopic hidden handle for a high-pressure ball valve.

Background

The valve is a control part in a transportation pipeline, the ball valve is one of a plurality of valves, the traditional valve is only used for connecting or cutting off media in the pipeline, such as the ball valve, and the like, under the conditions that the pressure test is carried out on the pipeline or the pressure in the pipeline is increased by using a pressure pump, the common ball valve cannot adapt to the high pressure in the pipeline, a high-pressure ball valve is used at this time, the high-pressure ball valve can bear higher pressure, the high-pressure ball valve is widely used in the industrial departments of petroleum, chemical industry, electric power, metallurgy and the like, the high-pressure ball valve also needs to be opened or closed by using a handle as other ball valves, the high-pressure ball valve needs to be opened or closed by the handle in the use process, the handles are arranged on a valve rotating shaft of the high-pressure ball valve, the handle is rotated to drive the valve rotating shaft to rotate, the valve is further opened or closed, sometimes, the handle is overlarge when a worker closes or opens the valve, the connection between the valve and the handle is too tight, so that the valve can be opened only by rotating the handle with a large force when the valve is opened or closed next time, the length of the traditional valve handle is fixed, and a worker needs to carry a handle extension sleeve when the valve is opened or closed too tight, so that the valve is convenient to close or open, the handle extension sleeves are long and inconvenient to carry, so that the high-pressure ball valve has defects in use, therefore, the telescopic handle is used for replacing the original handle in the prior art, the telescopic handle is mostly of a telescopic rod structure, one end of the telescopic rod is fixed on the side wall of a valve rotating shaft of the high-pressure ball valve, the other end of the telescopic rod extends outwards, the telescopic handle can extend, the high-pressure ball valve can be conveniently opened by the worker, the handle can be shortened, and the worker is prevented from mistakenly touching the handle when passing near the high-pressure ball valve, the valve is opened or closed, so that the normal transportation work of the pipeline is influenced;

however, the existing telescopic handle of the high-pressure ball valve still has the following disadvantages in practical use: although the existing telescopic handle with the high-pressure ball valve has a good using effect, in the using process, a worker cannot completely ensure that dust, dirt and moisture are not on the hand before operating the handle, the dirt and the moisture can be stained on the surface of the handle when the worker operates the handle, after the telescopic handle is used for a long time, the outer side wall of the telescopic handle can be stained with a large amount of dirt, the dirt and the moisture can slowly enter the telescopic rod in the telescopic process of the telescopic rod, the dirt contains the moisture, the moisture can slowly spread to each corner inside the telescopic rod in the telescopic process, when the telescopic rod is idle, the moisture inside the telescopic rod can be slowly diffused along with the time, the dirt is dried into a block dirt aggregate, even if the dirt entering the telescopic rod is less, the dirt inside the telescopic rod can be more and more accumulated along with the time, these spot aggregates can influence the normal flexible of telescopic link when the telescopic link is flexible, influence the normal use of current concertina type handle, and then influence the use of high-pressure ball valve, and current concertina type handle all fixes on the valve pivot, can't dismantle, and this use that just further influences high-pressure ball valve.
