Description

technical field [0001] The invention relates to the field of water supply and drainage of underground coal mines and petroleum pipelines, in particular to a gate valve and a control method for the gate valve. Background technique [0002] Due to its simple structure and good sealing performance, gate valves are widely used in water supply and drainage systems such as mines. The most common gate valve actuators on the market are handwheel switches. With the development of gate valves in the direction of high pressure, large diameter and automation, the handwheel switch actuator can no longer meet the demand. Therefore, an automatic execution scheme has emerged, mainly through the motor rotation and the reducer to increase the torque, replacing the handwheel mechanism. On the one hand, it can reduce labor intensity, and on the other hand, it is easy to realize remote control. [0003] However, there are still many problems in the existing automatic execution scheme: the main...
