Description

Technical Field

[0001] The utility model relates to a valve with a filtering function, belonging to the technical field of valves. Background Art

[0002] A valve is a device used to control the flow of fluids (such as liquids, gases, steam, etc.). Valves are usually used in piping systems to open, close or regulate the flow of fluids. Valves are of various types and uses, including manual valves, automatic valves, safety valves, regulating valves, etc. Valves are usually composed of a valve body, a valve cover, a valve core, a valve seat, etc.

[0003] In real life, in order to improve water quality and ensure the quality of domestic water, a filtering structure is set inside the valve to purify impurities in the water. For example, a Chinese utility model patent with announcement number CN220204694U provides a water conservancy project valve with filtering function, including a valve body, a mounting plate, a cover plate and a mounting assembly, a valve plate is fixedly installed in the valve body, a telescopic rod is slidably installed in the valve body, a valve head is fixedly connected to the bottom end of the telescopic rod, the valve head is connected to the valve plate, a screw is threadedly connected to the valve body, one end of the screw is fixedly connected to the telescopic rod, a turntable is fixedly installed on the other end of the screw, and a mounting hole is opened on the valve body. The valve with filtering function of the utility model is convenient for replacing the filtering structure, has a good filtering effect, and can effectively avoid clogging of the valve body.

[0004] In order to facilitate the installation of the filter plate in the above patent, it is necessary to open a mounting hole on the valve body, and then install the mounting plate in the mounting hole to install the filter plate.
