Check valve refers to a valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium.
Welding slag, rust, slag, etc. in the pipeline cause blockage or jam in the throttle, guide part, and balance hole of the lower bonnet, resulting in strain and scratches on the curved surface of the valve core,
With the development of society and economy, the use of valves is becoming more and more extensive, and there are many varieties of valves used in pipelines.
In the automatic control of modern factories, regulating valves play a very important role, and the production of these factories depends on the correct distribution and control of the flowing medium.
After the worm gear butterfly valve is installed and put into work, it is necessary to pay attention to the
maintenance of the worm gear butterfly valve.
The flow rate and flow rate of the valve mainly depend on the diameter of the valve, and it is also related to
the resistance of the valve structure to the medium.
Because air is compressible, the stability of pneumatic transmission system is poor. Compared with gas, the compressibility of hydraulic oil is small, so hydraulic transmission works smoothly.
What is the function of the valve of the high and low temperature cycle temperature control system? What problems
should be paid attention to when installing the valve?
As the name suggests, a low temperature valve is a valve that can work in cryogenic low temperatureconditions. To demarcate its working temperature, a valve with a working temperature below -40 °C is usually called a low temperature valve.
