A shale gas well high pressure stop valve

Abstract

The application discloses a high-pressure cut-off valve for shale gas well and belongs to the technical field of high-pressure shale gas exploitation equipment, and mainly solves the problem of overload fracture of a valve core caused by high-pressure unbalanced torque in the prior art. The cut-off valve comprises a valve body, a valve cover and a valve core, the valve body and the valve cover are connected through threads, and the valve core penetrates through the valve cover. The high-pressure cut-off valve can balance the unbalanced torque of high-pressure fluid through the structure of the plugging platform and the gyro-type boss, so that the driving energy consumption of the cut-off valve is reduced and the working efficiency is improved.
