Relief valve is through the adjustment, the import pressure will be reduced to a need of the export pressure, and rely on the energy of the medium itself, so that the export pressure to maintain the stability of the valve automatically. From the point of view of fluid mechanics, the pressure reducing valve is a local resistance can change the throttling element, that is, through changing the throttling area, the velocity of the fluid and kinetic energy change, resulting in different pressure loss, so as to achieve the purpose of decompression. And then rely on the control and adjustment of the system, so that the pressure of the valve after the pressure fluctuations and the spring force balance, so that after the pressure of the valve in a certain range of error remain constant.


Principle is that the role of valve by valve flow to reduce local resistance to the flow of water pressure, water pressure drop range from film to connect the valve or piston on both sides of the import and export automatically adjust the water pressure. Set than the decompression principle is to use the floating piston in the hydraulic valve body than the control, import and export and import and export side than the end of decompression piston area ratio is inversely proportional. This valve work smoothly without vibration; the valve body spring, so spring corrosion, metal fatigue failure of consideration; good sealing performance, no leakage, and therefore reduce both the dynamic pressure (water flow) and reduced static pressure (flow 0); particularly in the decompression at the same time does not affect the flow of water.


The flow through the valve has a lot of head loss, but because of reduced water waste and make a reasonable system flow distribution, improve the system layout and condition, so the whole is still such. Medium for steam occasions, should choose the pilot piston valve or pilot bellows type relief valve. In order to operate, convenient adjustment and maintenance, the valve should be installed in horizontal pipe.
