Description

Technical Field

[0001] The utility model relates to a valve, in particular to a connecting valve with a buffer structure, belonging to the technical field of valves. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves and regulating valves. Valves have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

[0003] A valve connector disclosed in the Chinese patent application disclosure specification CN220540322U drives a threaded connecting rod to rotate clockwise through a round handle, and drives a sliding rod and a stop block to move upward while the threaded connecting rod rotates clockwise. At this time, the valve body is flipped and the liquid can flow out to the right. By changing the number of rotations and the rotation direction of the round handle, the flow rate of the liquid can be adjusted, thereby improving the practicality of the device.

[0004] Although the solution of the above patent can adjust the flow of liquid, when high-pressure liquid passes through the valve, it will produce a strong impact force on the valve seat. Especially when the valve is opened or closed quickly, the liquid will produce a water hammer effect in the pipeline, resulting in violent pressure fluctuations. This pressure shock may damage the valve seat, causing the valve seat to wear, resulting in cracks or peeling, further reducing the sealing performance and life of the valve. Utility Model Content
