Description

Technical Field

[0001] The utility model relates to the technical field of Y-type filters, and more specifically to a Y-type filter for a valve faucet. Background Art

[0002] In the pipes where water flows, a Y-type filter is used "upstream or downstream" of the valve faucet to protect the valve and the entire pipe system from damage by impurities;

[0003] The Y-type filter has a significant design feature, that is, its shape is like the letter "Y". In this "Y"-shaped structure, there is a removable filter screen, which is usually located before the fluid enters the straight pipe section of the valve or piping system; this design allows solid particles, residues or other impurities to be trapped in the filter screen when the fluid passes through the filter, thereby ensuring the cleanliness of the fluid and protecting subsequent valves, pumps or other precision equipment from clogging or wear;

[0004] The existing general Y-type filter {such as the public (publication) number: CN207575937U, a Y-type filter} or {such as the public (publication) number: CN202802944U, a Y-type filter}, etc., its structure needs to be provided with a raised platform on the inner side of the straight tube in order to provide sealing support for the tubular filter component, but the setting of the raised platform will greatly limit the flow space when the water passes, and there is a disadvantage of poor structural rationality.

[0012] As a preferred technical solution of the utility model, the fixing member is a bolt, and the bolt penetrates the fixing ring and the fixing plate at the same time to fit and fix them.

[0013] As a preferred technical solution of the utility model, it also includes a guide component arranged between the inclined tube and the tubular filter screen for directional displacement of the tubular filter screen in the inclined tube into the annular groove.

[0014] As a preferred technical solution of the utility model, the guide assembly includes a strip guide groove arranged in the inclined tube, and a guide bar fixedly arranged outside the tubular filter, and the guide bar moves in the strip guide groove.

[0015] The beneficial effects of the utility model are as follows:

[0016] The annular groove 4 is formed by setting a part of it on the inner wall of the straight tube 1, and the other part is set on the convex strip 3, and the convex strip 3 is fixedly set in the straight tube 1 and the inclined tube 2. After the annular groove 4 is set at this position, the tube end of the tubular filter 5 is inserted and pressed, which can greatly reduce the space that restricts the flow of water when passing through, and improve the rationality of the structure;

[0017] At the same time, a guide assembly 7 is provided between the inclined tube 2 and the tubular filter 5 to direct the displacement of the tubular filter 5 into the annular groove 4 in the inclined tube 2, thereby ensuring that the tubular filter 5 is quickly and accurately placed into the annular groove 4 to simplify the operation process.
