The main function of pressure reducing valve

         Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, QD bushes, bolt-on hubs, sprocket gear，torque limiters, shaft collars, motor bases and motor slides, chain detachers, stainless steel chain，chain guides,roller chain, universal joint, rod ends and yokes. Our products are used in many different industry sector, like in automation engineering, drive engineering, conveyor technology, assembly and handling technology, packaging industries, the beverage, food and medical engineering, pharmaceutical production, and laboratory equipment.

       Valves through regulation, the inlet pressure is reduced to a desired outlet pressure, and rely on the energy medium itself, so that the outlet pressure automatically to maintain the stability of the valve. From the viewpoint of fluid mechanics, the valve is a throttling element of a local resistance to change, or by 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. Relying on the control and adjusting system, thefluctuation and the spring force the valve after the pressureequilibrium, so that the valve after the pressure was maintainedconstant at a certain range of error.

     The main role

     Mechanism of the pressure reducing valve in the valve is to rely onlocal resistance to water flow to reduce the 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 thefloating piston in the hydraulic valve body than the control, import and export and import & export side than the end of decompressionpiston area ratio is inversely proportional to.

     This valve work smoothly without vibration; valve body there is no spring, so no spring corrosion, metal fatigue failure of consideration; seal leakage performance is not good, so not only by the dynamic pressure(water flow) and reduced static pressure (flow 0); particularly in the decompression at the same time does not affect the water flow.

   The flow of water 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 generally speaking the energy-saving. Medium for steam occasions, should choose the pilot piston valve or pilot bellows type relief valve. In order to operate, adjustment and repair convenient,general relief valve should be installed in horizontal pipelines.
