Regarding the selection, use, and maintenance of valves, you should know that these valves are commonly used accessories in pumps and other equipment, including gate valves, butterfly valves, ball valves, globe valves, safety valves, etc. Today, we will talk about the selection, use, and maintenance of valves.
How to choose a suitable valve that can adapt well to working conditions and achieve twice the result with half the effort?
There are many types of valves, and when selecting, consideration should be given to the properties of the medium, working pressure, working temperature and their range of variation, the diameter of the pipeline and special process requirements (throttling, pressure reduction, venting, check, etc.), the installation position of the valve, and other factors. The basic principles of "meeting process requirements, safety and reliability, economic rationality, and easy operation and maintenance" should be followed when selecting the corresponding valve.
①For pipelines with bidirectional flow, non directional valves such as gate valves, ball valves, and butterfly valves should be selected; For pipelines that only allow one-way flow, check valves should be selected; For areas where flow needs to be adjusted, multiple throttle valves can be selected, and globe valves can also be used when precise adjustment is not required.
②For pipelines that require rapid opening and closing, ball valves or butterfly valves should be selected; For pipelines that require good sealing, gate valves or ball valves should be selected.
③For pressure vessels and pipelines, safety valves should be installed according to their specific conditions. For various gas cylinders, a pressure reducing valve should be installed at the outlet.
