The proportional pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure by adjusting, and mainly relies on the energy of the medium itself when working, and then automatically keeps the outlet pressure stable. Below for everyone to introduce the basic principle of proportional pressure reducing valve and the advantages and disadvantages.
The proportional pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure by adjusting, and mainly relies on the energy of the medium itself when working, and then automatically keeps the outlet pressure stable. Below for everyone to introduce the basic principle of proportional pressure reducing valve and the advantages and disadvantages.
Proportional pressure reducing valve before it is used, we need to know more information. So it from the point of view of fluid mechanics, in fact, the proportional pressure reducing valve is a local resistance can change the throttling element, in the work of that by changing the throttle area, the flow rate and the kinetic energy of the fluid change, in this case will cause different pressure loss, so as to achieve the purpose of decompression. In the future, when everyone sees it, they should only scan its basic information. Then, relying on the adjustment of the control and adjustment system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain error range. The performance of the proportional pressure reducing valve is also very clear. For example, it refers to the adjustable range of the pressure reducing valve output pressure P2, so it will be required to achieve the specified accuracy within this range. The pressure regulating range is mainly related to the stiffness of the pressure regulating spring. In addition, we also need to be clear at the time that its pressure characteristics mainly refer to the characteristics of output pressure fluctuations caused by input pressure fluctuations when the flow g is a fixed value. At this time, the smaller the output pressure fluctuation, the better the characteristics of the pressure reducing valve.
So its characteristics are also very clear. Moreover, the output pressure must be lower than the input pressure-the fixed value is basically unchanged with the change of input pressure. The pressure of the proportional pressure reducing valve changes with the change of the output flow g. When the flow rate g changes, the smaller the change in pressure, the better. Generally, the lower the pressure, the smaller the fluctuation with the change of the output flow. As far as the current situation is concerned, its advantages are also relatively large. Moreover, it is widely used in high-rise buildings, areas with high water pressure of urban water supply network, mines and other occasions to ensure that each water point in the water supply system obtains appropriate service water pressure and flow. It can also be seen in these places. Of course, it is also in view of the leakage rate of water and the degree of waste is almost proportional to the water pressure of the water supply system, so the pressure reducing valve has the effect of improving the operating conditions of the system and potential water saving. According to statistics, its water saving effect is about 30%. If there are any questions you don't understand, you can call us at any time for consultation.
