In order to facilitate the control of fluid pressure in industrial and civil fields so that each device can be used normally, self-operated pressure regulating valves are used to divert, merge or switch the flow direction of the fluid.
[0003] During the use of the self-operated pressure regulating valve, the action force generated by the internal fluid is balanced with the reaction force of the spring, thereby controlling the pressure behind the valve through the relative position of the valve core and the valve seat. However, during the use of the existing self-operated pressure regulating valve, the internal vibration is easy to generate noise, and the vibration is easy to affect its own stability. Therefore, a self-operated pressure regulating valve with shock absorption and pressure stabilization is proposed to solve the above problems. Utility Model Content
