Background

The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so that when the valve is closed, pressure must be applied to the valve clack so as to force the sealing surface not to leak. When fluid medium enters the valve from the lower part of the valve clack, the resistance which is needed to be overcome by the operation force is the friction force of the valve rod and the packing and the thrust generated by the pressure of the medium, and the force for closing the valve is larger than the force for opening the valve, so that the diameter of the valve rod is larger, otherwise, the valve rod is in a bending-over fault. The valve rod is used for driving the valve clack to reciprocate when the stop valve works, so that the communication or the separation of a flow channel is realized, the existing stop valve is easy to open because of the hydraulic pressure, and the valve rod is used for solving the problem.
