[0025] Working principle or structural principle: When in use, the upper cover tube 1 serves as the main body of the filter, and a filter core 2 is arranged inside. The filter core 2 is used to intercept impurities and particulate matter in the fluid. The lower end of the upper cover tube 1 is connected to the inner tube 3 by a snap-on method to ensure that the fluid can pass smoothly. A lower branch pipe 4 is arranged at the bottom of the inner tube 3, and a connecting pipe 5 is arranged inside the lower branch pipe 4 to connect to external pipelines or equipment. The upper cover tube 1, the inner tube 3, the lower branch pipe 4 and the connecting pipe 5 are all made of 304 industrial stainless steel. 304 industrial stainless steel has good corrosion resistance and mechanical strength, and can maintain stable filtering performance under harsh working conditions. The filter core 2 uses ultra-fine glass fiber filter paper It is made of, has extremely high filtering accuracy and dust holding capacity, can effectively intercept tiny particles in the fluid, and ensure the cleanliness of the fluid. When the fluid passes through this device, it first enters the upper cover pipe 1 and flows through the filter element 2. The filter element 2 uses the filtering effect of ultra-fine glass fiber filter paper to intercept impurities and particles in the fluid on the surface or inside of the filter paper. The filtered fluid then enters the inner through pipe 3, and flows out of the filter through the lower branch pipe 4 and the connecting pipe 5 to enter the subsequent equipment or pipeline. At the same time, this device adopts a special sealing structure at the interface to ensure that the fluid will not leak during the filtering process. The sealing material can be selected according to the use environment to meet the sealing requirements under different working conditions.
