Description

Technical Field

[0001] The invention relates to the field of stop valves, in particular to a high-sealing stop valve. Background Art

[0002] The stop valve, also known as the gate valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage.

[0003] A highly sealing stop valve is disclosed in a patent document with Chinese patent publication number CN207195670U. When the valve disc moves downward, the resistance between the first conical wall and the second conical wall gradually increases, and the sealing performance is gradually improved. The conical surface is evenly stressed, the sealing area is large, and it is not easy to wear, thereby further improving the sealing performance between the valve disc and the valve port.

[0004] Although the above patent can improve the sealing between the valve disc and the valve port, a large force needs to be applied when opening and closing the valve. When the existing equipment turns the valve handle, there are no auxiliary parts, which is easy to slip and inconvenient to exert force. It is more laborious to open and close the valve. There is no protective equipment on the outside of the stop valve, and it is easy to freeze when used in winter, affecting its use. Summary of the invention
