Background
The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so when the valve is closed, pressure must be applied to the valve clack to force the sealing surface not to leak. When the medium enters the valve from the lower part of the valve clack, the resistance to be overcome by the operating force is the friction force between the valve rod and the packing and the thrust generated by the pressure of the medium, the force for closing the valve is larger than the force for opening the valve, so the diameter of the valve rod is larger, otherwise the failure of the valve rod buckling can occur. The connection mode is divided into three types: flange connection, screw thread connection and welding connection. After the self-sealing valve appears, the medium flow direction of the stop valve is changed to enter the valve cavity from the upper part of the valve clack, at this time, under the action of medium pressure, the force for closing the valve is small, the force for opening the valve is large, the diameter of the valve rod can be correspondingly reduced, the opening and closing piece of the stop valve is a plug-shaped valve clack, the upper surface of the seal is a plane or a sea cone surface, and the valve clack makes linear motion along the central line of the valve seat. The movement form of the valve rod, also a lifting rotating rod type, can be used for controlling the flow of various types of fluid such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like.
