Introduction of various types of instrument valves
There are too many types of instrument valves, and there may be other classifications, but they are still suitable for gate valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plunger valve, plug valve, check valve, safety valve, pressure reducing valve, steam trap, etc. used in industrial pipelines.
Instrument valve is a kind of pipeline accessory. It is used to change the channel section and medium flow direction, and control the medium flow.
Instrument valve has the advantages of tight connection, easy installation and disassembly, good fire protection, explosion-proof, high pressure resistance and good sealing performance. It is the preferred valve type in power station, oil refining, chemical plant and instrument measurement pipeline.
When the user installs the instrument valve, the valve will be installed reversely without paying attention. The reverse installation of the arrow direction of the instrument valve will not affect the reading of the instrument, especially in the fully open state; But there will also be some impact, which is determined by the structure of the instrument valve. Usually, the fluid in the valve body is designed according to the principle of down in and up out. The valve core is on the top, that is, the fluid flows from the bottom through the throttle hole of the valve seat, and then flows out through the gap between the valve core and the valve seat. The throttle piece composed of the inner diameter of the valve seat and the valve core plays a regulating role.
