How to actually solve the problem of how to choose the valve material
The regulating valve is a device for adjusting fluid water pressure, flow rate, temperature, etc. In modern automatic control, the regulating valve has a very large effect. He can adjust the transfer fluid to meet the job requirements. According to different actuators, it can be divided into pneumatic control valve, hydraulic control valve and electric control valve . Play your own role in different places, according to the transmission of different fluids, how to choose the valve material to meet the needs of work.
Pure fluid
There is no requirement for the fluid, such as water, you can choose the general material. Zui is considering the price superiority. Because the fluid is transmitted, the damage to the valve is very small. Therefore, when using the valve, the price of the valve is mainly considered.
Corrosive, high temperature pressure
This kind of fluid is special, and it will be eroded for pipes, door valves and pump bodies. The material is not required for door valves and it is easy to directly damage. Therefore, in the transmission of corrosive, high-temperature pressure fluid, Zui is better to choose the corrosion-resistant material, which can reduce the erosion of the valve on the valve and prolong its service life.
Scouring fluid
When the fluid is transferred, the door valve will have a large impact force, and the interior of the door valve will be flushed. The general material door valve is in such an environment for a long time, and the degree of wear is very large, which will shorten the use time of the valve. Therefore, when transferring fluid, Zui chooses the wear-resistant material to prevent the fluid from over-washing the gate valve.
