The closing principle of the stop valve is that the sealing surface of the valve clack is tightly attached to the sealing surface of the valve seat by means of the pressure of the valve rod, and the medium is prevented from flowing. The valve plays an important role in cutting off and throttling the medium in the pipeline where the valve is located; the stop valve is an extremely important cut-off valve, and the sealing of the stop valve is realized by applying torque to a valve rod and applying pressure to a valve clack by the valve rod in the axial direction, so that a sealing surface of the valve clack is tightly attached to a sealing surface of a valve seat, and a medium is prevented from leaking along a gap between the sealing surfaces.
