Description

Technical Field

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

[0002] With the development of the economy and the continuous improvement of people's living standards, water, natural gas, etc. used in daily life need to be transported through pipelines. During transportation, valves are needed. Valves are control components in fluid transportation systems and have functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

[0003] When water pipes are transporting water, there will be impurities inside. Generally, a filter is set inside the valve for filtering. However, the filter inside the existing valve only blocks the impurities. Over time, a large amount of impurities will adhere to the filter, causing the water flow rate to slow down. It cannot be cleaned from the outside, affecting the use of the filter. The valve body needs to be disassembled for cleaning, which is complicated to operate and inefficient. Therefore, a valve with a filtering structure is proposed. Utility Model Content

A drain pipe 17 is fixedly installed on the surface, and a one-way valve is arranged inside the drain pipe 17. The arrangement of the drain pipe 17 can facilitate the cleaning of the cleaned impurities. A water outlet pipe 18 is fixedly installed on the right side of the valve body 1, and a connecting pipe 19 is fixedly installed on the bottom surface of the water outlet pipe 18, and an electromagnetic valve is arranged inside the connecting pipe 19. The arrangement of the connecting pipe 19 facilitates the injection of liquid into the valve body 1 to flush the internal impurities. A connecting flange 20 is fixedly installed on the left side of the water inlet pipe 5, and a connecting flange 20 is fixedly installed on the right side of the water outlet pipe 18.
