Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a soft-sealed gate valve which is convenient for replacing the gate valve. Background Art

[0002] Soft-sealed gate valve, industrial valve, the opening and closing part of the soft-sealed gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. Through the nut in the middle of the gate and the guide groove on the valve body, the rotary motion is converted into linear motion, that is, the operating torque is converted into operating thrust. When the valve is opened, when the gate lifting height is equal to 1:1 times the valve diameter, the fluid channel is completely unblocked.

[0003] The existing soft-sealed gate valve cannot be replaced according to the damaged structure, which increases the maintenance cost of the device. At the same time, when the gate of the soft-sealed gate valve is damaged and needs to be replaced, it is necessary to waste manpower and time to find the valve of the external pipeline to close it, and then disassemble and replace the soft-sealed gate valve, which is inconvenient to use. Therefore, we propose a soft-sealed gate valve that is easy to replace the gate valve. Utility Model Content
