Abstract
The emergency cut-off device for the wellhead comprises a wellhead valve, a trigger mechanism and a power assisting mechanism, the wellhead valve is installed on a pipeline, the trigger mechanism triggers the power assisting mechanism to control the valve to be connected and disconnected, and the trigger mechanism comprises a locking mechanism, a connecting rod mechanism and a control box. An electric control assembly and an adjusting control assembly are arranged in the control box, a trigger mechanism and a power assisting mechanism are arranged on the wellhead valve, an adjusting screw rod is arranged in the power assisting mechanism, an adjusting handle is arranged at the front end of the power assisting mechanism, and the trigger mechanism is provided with a connecting rod device and a piston assembly. And a low-pressure adjusting structure and a high-pressure adjusting structure are arranged in the connecting rod device. A manual cut-off structure and a remote control cut-off structure are combined on the basis of an existing cut-off valve, the response speed is high, and the device is easy to reset.
