Remote transmission and remote control wellhead protector

The utility model relates to a remote transmission and remote control wellhead protector, which belongs to the technical field of oil and gas well valve control and comprises a gate valve and a gas transmission pipeline, one end of the gate valve is communicated with the gas transmission pipeline, and the other end of the gate valve is connected with a clutch for controlling the gate valve to cut off or open an internal passage of the gas transmission pipeline. The end, away from the gate valve, of the clutch is connected with an actuator for connection or disconnection of the clutch and the gate valve, the gas conveying pipeline is connected with two pressure sensors, the two pressure sensors are distributed on the two sides of the gate valve, and the actuator is provided with a control unit used for collecting signals sent by the sensors. The gas pipeline pressure control device has the effect that when the pressure of the gas conveying pipeline is abnormal, a gas source at a well head can be rapidly cut of
