The working principle of the utility model is as follows:
when the valve is used, the pressure relief opening 13 is connected with the valve, when the valve connected with the pressure relief opening 13 is opened, pressurized water in the piston working cavity 15 is relieved through the pressure relief opening 13, the pressure of the spring 4 borne by the piston 7 is larger than the pressure of the water borne by the piston 7, the piston 7 drives the valve core 3 to be opened downwards through the valve rod 9, so that the liquid inlet 11 is communicated with the liquid outlet 12, and the valve is opened.
After the valve is opened, when the medium flows, the valve core 3 and the valve body 1 form throttling to cause pressure loss, the pressure at the liquid inlet 11 is forced to be reduced by a certain required value at the liquid outlet 12, and when the flow and the pressure change, the energy of the medium is utilized to control the outlet pressure to be basically unchanged. When the pressure of the liquid outlet 12 is regulated, the regulating bolt 6 is rotated to change the precompression amount of the spring 4, so that the compression amount of the spring 4 caused by the water pressure borne by the valve rod 9 is changed, the valve rod 9 drives the valve core 3 to move for a certain distance, the throttling area is changed, and the purpose of regulating the outlet pressure is achieved.
When the valve connected with the pressure relief opening 13 is closed, the water pressure in the piston working cavity 15 is not relieved through the pressure relief opening 13, the water pressure borne by the piston 7 is larger than the sum of the pressure borne by the spring 4 and the water pressure borne by the valve core 3, at the moment, the piston 7 drives the valve core 3 to be closed upwards through the valve rod 9, so that the liquid inlet 11 is separated from the liquid outlet 12, and the valve is closed.
