Description

Technical Field

[0001] The utility model relates to a valve body accessory with a filtering structure, belonging to the technical field of valve bodies. Background Art

[0002] In the fluid pipeline system, the valve is a control element. Its main function is to isolate equipment and pipeline systems, regulate flow, prevent backflow, regulate and discharge pressure. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The final control of the pipeline is the valve. The valve opening and closing parts control the flow pattern of the medium in the pipeline. The shape of the valve flow channel gives the valve certain flow characteristics.

[0003] In order to filter impurities in the fluid, the existing valve body shell structure usually sets a filter screen inside the valve body to filter the impurities inside the fluid through the filter screen. However, the existing valve body internal filter screen structure is directly placed and set. Such a structure has too low supporting strength, which will cause damage to the filter screen. At the same time, the filtered impurities will be blocked together, affecting the normal flow of the fluid. Utility Model Content
