Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a pressure regulating valve. Background Art

[0002] A pressure regulating valve is a device used to adjust and control the flow, temperature, pressure and other parameters of the medium in the pipeline. There are many types of pressure regulating valves, which can be divided into two categories according to their structure: linear travel and angular travel, a total of nine types. They can also be classified according to their use and function, main parameters, pressure, medium working temperature, special purpose, driving energy and other methods.

[0003] Most of the existing pressure regulating valves block the valve passage, thereby regulating the pressure by changing the size of the passage. This blocking will cause the direct flow of the internal fluid to become turbulent flow, thereby causing excessive local pressure changes. Therefore, it is necessary to propose a pressure regulating valve. Utility Model Content
