I will explain some basic knowledge of regulating valves.

The regulating valve is a control component in the pipeline fluid conveying system. It is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cutoff, regulation, throttling, check, diversion or overflow relief.

Regulating valves for fluid control, from the simplest shut-off valves to the various regulating valves used in extremely complex automatic control systems, with a wide variety and specifications, the nominal diameter of the regulating valve ranges from very small instrument valves to diameters Valves for industrial pipes up to 10m. The regulating valve can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metal and radioactive fluid. The working pressure of the regulating valve can be from 1.3х10MPa to 1000MPa. The operating temperature ranges from an ultra-low temperature of -269 ° C to a high temperature of 1430 ° C. The control of the regulating valve can be driven by various transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic motion, electromagnetic-hydraulic, electro-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive. Etc.; can be operated according to predetermined requirements under the action of pressure, temperature or other forms of sensing signals, or simply turned on or off without relying on the sensing signal, and the regulating valve is driven or automatically to raise and lower the opening and closing member. , slip, swivel or swivel motion to change the size of its runner area to achieve its control function.

Regulating the use of the valve

The regulating valve is a pipe fitting, which is a device for changing the passage section and the flow direction of the medium to control the movement of the conveying medium, and has the functions of diversion, cutoff, regulation, throttling, check, split or overflow relief. And other functions. Specifically, the regulating valve has the following uses:

1 Cut-off valve class: Turns on or off the media in each section of the pipe. Such as gate valves, globe valves, ball valves, plug valves, diaphragm valves, butterfly valves, etc.

2 Regulating valve type: Adjust the flow and pressure of the medium in the pipeline. Such as throttle valves, regulating valves, pressure reducing valves, safety valves, etc.

3 Diverter valve: Change the flow direction of the medium in the pipeline to distribute, separate or mix the medium. Such as distribution valves, three-way plug valves, three-way or four-way ball valves, traps and so on.
