Description
Pressure reducing valve is by adjusting the inlet pressure to a needed outlet pressure, and rely on the energy of the medium itself, so that the outlet pressure automatically maintain a stable valve.From the point of view of fluid mechanics, pressure reducing valve is a local resistance can change the throttle element, that is, by changing the throttling area, so that the flow rate and fluid kinetic energy change, causing different pressure loss, so as to achieve the purpose of decompression.Then rely on the control and regulation of the system, so that the valve after the pressure fluctuations and spring force balance, so that the valve after the pressure in a certain error range to maintain a constant.
