[0002] A valve is a device used to control or regulate the flow of fluids (such as liquids, gases, vapors, etc.). It can control the flow, pressure, and direction of fluids by opening or adjusting the opening of the valve. The valve is usually composed of a valve body, a valve cover, a valve flap (or a valve core), a sealing element, and an operating mechanism.

[0003] The existing valve locking mechanism generally passes through the hole in the bottom of the handle, and the lock passes through the handle hole and the lock plate hole to complete the locking. When the valve is limited by space or needs to be covered with a thermal insulation layer, the valve handle needs to be raised, and the operator cannot access the original locking position of the handle, which causes inconvenience to the locking of the valve, and even cannot be locked. Some products on the market raise the locking surface and the positioning surface at the same time to achieve the locking function. This not only increases the overall weight of the valve, but also increases the cost. Moreover, it increases the transmission chain error of the valve, which causes the valve to be unable to fully open, and seriously affects the performance of the valve. SUMMARY
