Electro-hydraulic drive gas gate valve with stress detection function and control system

The invention belongs to the technical field of gas gate valves, and particularly relates to an electro-hydraulic drive gas gate valve with a stress detection function and a control system. The valve comprises a valve body arranged on a gas pipeline in a sleeving manner, a gate plate installed in the valve body, a valve deck installed on the gate plate, an electro-hydraulic actuator fixedly installed on the valve deck, an integrated valve rod arranged in the electro-hydraulic actuator in a sleeved manner, a displacement detection device inserted into the integrated valve rod, a data acquisition and wireless transmission module fixedly arranged at the end part of the electro-hydraulic actuator, and a stress detection device arranged at the tail part of the integrated valve rod. The electro-hydraulic actuator is applied to driving of the gas gate valve, the electro-hydraulic actuator can be applied to small-caliber and low-torque gas gate valves and can also be applied to large-caliber and high-torque gas gate
