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.
Most of existing stop valves are water pipes with two ends directly connected, the shock resistance of the existing stop valves is poor, and certain potential safety hazards are caused due to the fact that the stop valves fall off easily when shock occurs.
