What are the advantages of pressure reducing valves? I believe that many friends are not clear, in order to enhance everyone's understanding, the following Xiaobian to introduce this problem in detail, interested to see together! If you're interested, check it out here.

The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure by adjusting it and automatically maintains the stability of the outlet pressure by relying on the energy of the medium itself. From a fluid mechanics point of view, it is indeed a throttling element, in simple terms, it can change the local resistance, that is, by changing the throttling area, changing the flow rate and kinetic energy of the fluid, resulting in different flow rates. Pressure loss, to achieve the purpose of decompression. Then relying on the adjustment of the control and adjustment system, the spring force is used to balance the fluctuation of the pressure after the valve, so that the pressure of the reducing valve is kept constant within a certain error range. When working, the water pressure is mainly reduced by the local resistance of the flow channel in the water flow valve. The water pressure drop range is automatically regulated by the difference in water pressure between the inlet and outlet on both sides of the piston and the diaphragm attached to the valve disc. The principle of pressure reducing valve is to control the water pressure ratio of the floating piston in the valve body, and the decompression ratio of the inlet and outlet ends is inversely proportional to the area ratio of the inlet and piston. So everyone should know that this kind of work is smooth, no vibration.

There is no spring in the valve body of the relief valve, so there is no need to worry about spring corrosion and metal fatigue failure; Good sealing performance, no leakage, reducing dynamic pressure (when water flows) and static pressure. Pressure (when the flow rate is 0); In particular, the pressure reducing valve does not affect the flow of water and reduces the pressure. It also mainly uses the opening stage of the opening and closing parts in the valve body to adjust the flow rate of the medium, reduce the pressure of the medium, and at the same time, by adjusting the opening stage of the opening and closing parts, the pressure after the valve is maintained within a certain range, and the cooling water is injected into the valve body or after the valve, at this time, the temperature of the medium can be reduced. Pressure and temperature reducing valves. Includes fast, simple and optimized automatic selection of pressure reducing valves. The characteristic of the reducing valve is that the outlet pressure and temperature can be kept in a certain range when the inlet pressure is continuously changed. Although the head loss is large, but because of the reduction of water waste, so that the system distribution is reasonable, improve the system layout and working conditions, the overall energy saving. When the medium is steam, it is appropriate to choose pilot piston reducing valve or pilot bellows reducing valve. In order to facilitate operation, adjustment and maintenance, the pressure reducing valve should generally be installed on the horizontal pipeline.

The above article is about the advantages of the pressure reducing valve for all friends, and in the content also shared a better manufacturer, if you have this need can go to check it, I hope to bring you help. As the main product of our factory, thanks to the strong support of new and old customers, we ensure the reliability of product quality at the same time, so that the majority of customers.

 

What are the uses of pressure reducing valves?

The development prospect of the pressure reducing valve industry is very good, because it brings more benefits to the enterprise when it is used, so it is favored by customers, in order to let you know more, next we will tell about the use of the pressure reducing valve, and hope to help more people.

What should I pay attention to when using pressure reducing valve?

The application range of pressure reducing valve is very wide, we must know the precautions of using pressure reducing valve before use, so that we can better apply it. If you are interested in this topic, let's take a look and hopefully help some of the people involved.
