Description

Technical Field

[0001] The present application relates to the technical field of filters, and in particular to a Y-type filter made of PPR material. Background Art

[0002] With the rapid advancement of industrialization and urbanization, water pollution is becoming increasingly problematic, posing a direct threat to residents' quality of life and health. Therefore, ensuring the safety of water in water supply pipelines and reducing the risk of disease caused by water quality issues have become crucial issues in protecting residents' lives. In this context, filter fittings, as core components of tap water piping systems, have a direct impact on the safety and quality of tap water through their performance and quality.

[0003] Existing filter fittings primarily consist of a pipe body and a built-in filter element. The pipe body connects the piping system and ensures smooth water flow, while the filter element, made of high-efficiency filter materials such as metal mesh and PP cotton, effectively intercepts and removes impurities from the water. This design significantly improves water quality and provides residents with relatively safe drinking water.

[0004] However, as usage increases, a large amount of impurities accumulate on the filter element, which not only reduces its filtration efficiency but may also cause secondary contamination to the water quality. Therefore, regular inspection and replacement of the filter element is particularly important. However, the problem is that the existing pipe body and the connecting pipe end are usually connected by hot melt. Although this connection method is stable, the subsequent disassembly and assembly process when the filter element needs to be replaced or inspected is cumbersome and time-consuming, seriously affecting maintenance efficiency, leaving room for improvement. Utility Model Content

[0005] The purpose of this application is to provide a Y-type filter made of PPR material to solve the problem of low disassembly and assembly efficiency of the filter pipe during subsequent maintenance of the filter core in the above-mentioned related technology.

[0006] The Y-type filter made of PPR material provided in this application adopts the following technical solution:

[0007] A Y-type filter made of PPR material includes a pipe body, wherein a water inlet chamber and a water outlet chamber are provided inside the pipe body, and a barrier plate separating the water inlet chamber and the water outlet chamber is fixedly provided on the inner wall of the pipe body; an extension tube is fixedly provided at an angle on the outer periphery of the pipe body, a filter chamber is provided in the extension tube, a water inlet connected to the water inlet chamber is opened on the bottom side of the filter chamber, a filter element is provided at the water inlet in the filter chamber, a filter port connected to the water outlet chamber is opened on the side wall of the filter chamber, and an end cap is fixedly provided at the opening of the extension tube away from the pipe body.

[0008] By adopting the above technical solution, when the filter tube is used, water is first injected into the water inlet chamber, and then injected into the filter chamber through the water inlet. It needs to be filtered by the filter element and then injected into the water outlet chamber from the filter port to filter impurities in the water; in addition, due to the coordinated arrangement of the extension tube and the filter element, the filter sleeve can be quickly inspected or replaced by removing the end cover, which consumes less time and is more efficient.

[0009] Optionally, the filter element is a filter sleeve arranged in the filter cavity, and filter holes are evenly opened on the outer circumference of the filter sleeve; one end of the filter sleeve is tightly pressed against the inner edge of the water inlet, and the other end is tightly pressed against the inner side surface of the end cover, and there is a gap between the outer circumference of the filter sleeve and the inner wall of the filter cavity.

[0010] By adopting the above technical solution, since the filter element is a filter sleeve, after the filter sleeve is installed, one end is pressed against the inner edge of the water inlet, and the other end is pressed against the inner side surface of the end cover, thereby reducing the possibility of the filter sleeve being loosened in the filter cavity and enhancing the installation stability of the filter sleeve.

[0011] Optionally, a positioning groove for inserting the end of the filter sleeve is provided on the inner side surface of the end cover.

[0012] By adopting the above technical solution, after the filter sleeve is installed, the end portion close to the end cover is inserted into the positioning groove on the end cover, thereby further enhancing the installation stability of the filter sleeve.

[0013] Optionally, an annular groove for inserting the end of the filter sleeve is provided on the bottom side of the filter cavity.

[0014] By adopting the above technical solution, after the filter sleeve is installed, the end away from the end cover is inserted into the annular groove, thereby further enhancing the installation stability of the filter sleeve.

[0015] Optionally, filter cotton is fixed on the inner wall of the filter sleeve.

[0016] By adopting the above technical solution, the filter cotton is fixedly installed on the inner wall of the filter sleeve, thereby achieving double filtration of the transported medium and enhancing the filtering effect.

[0017] Optionally, an external thread is provided on the outer periphery of the end cover, an insert is embedded on the inner wall of the opening of the extension tube, and an internal thread that matches the external thread on the end cover is provided on the inner wall of the insert.

[0018] By adopting the above technical solution, when the end cover is fixed on the extension tube, due to the threaded cooperation between the internal thread and the external thread, the end cover can be screwed into the insert to achieve the installation and fixation of the end cover, thereby improving the installation efficiency of the end cover.

[0019] Optionally, a protrusion is fixedly provided on the outer surface of the end cover, and the cross-sectional shape of the protrusion is a regular hexagon.

[0020] By adopting the above technical solution, the user can use a tool such as a wrench to clamp on the protrusion, thereby driving the end cover to rotate, which facilitates the subsequent installation of the end cover.

[0021] Optionally, a retaining ring is fixed on the outer edge of the side of the end cover away from the extension pipe, and a sealing gasket is sleeved on the outer periphery of the end cover. After the end cover is installed, both sides of the sealing gasket can be tightly pressed against the retaining ring and the extension pipe respectively.

[0022] By adopting the above technical solution, when the end cover is fixed on the extension tube, the sealing retaining ring is pre-mounted on the outer periphery of the end cover, and the end cover is screwed into the insert until the two sides of the sealing gasket are respectively tightly pressed against the retaining ring and the extension tube; thereby, the sealing performance of the joint between the end cover and the extension tube is enhanced, and the possibility of leakage of the conveyed medium from the joint between the end cover and the extension tube is reduced.

[0023] Optionally, a control handle is hinged on the outer side of the end cover, and a receiving groove for the control handle to rotate is provided on the side of the end cover away from the extension tube.

[0024] By adopting the above technical solution, when needed, the user can rotate the control handle out of the accommodating groove and drive the end cover to rotate through the control handle; when not needed, the control handle can be rotated back into the accommodating groove and stored.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Due to the coordinated arrangement of the extension tube and the filter element, the filter sleeve can be quickly repaired or replaced by removing the end cover, which saves time and improves efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
