[0023] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0024] A split and detachable pipeline filter for a water pipeline is installed before a water-using device with specific water quality requirements and after the stop valve of the water pipeline, serving as a part in the middle of the fixed pipeline. When in use, close the stop valve of the water pipeline, loosen the lever-type locking mechanism on the female flange 1 of the quick connector, and open the snap-on quick-connect pipeline clamp 6, then the filter assembly composed of the conical filter cartridge 3, the polytetrafluoroethylene gasket 4, and the male connector pipe 5 of the quick connector can be removed to clean the debris and replace the filter cartridge. After resetting the filter assembly, lock the lever, close the snap-on quick-connect pipeline clamp 6, and open the stop valve of the water pipeline to resume use, thus achieving rapid cleaning of the debris in the filter cartridge and rapid replacement of the filter cartridge.

[0025] The split and detachable pipeline filter for the water pipeline includes a female flange 1 of the quick connector, a silicone rubber sealing ring 2, a conical filter cartridge 3, a polytetrafluoroethylene gasket 4, a male connector pipe 5 of the quick connector, a snap-on quick-connect pipeline clamp 6, and an outlet flange pipe 7.

[0026] The female flange 1 of the quick connector, as the starting end of the split and detachable pipeline filter for the water pipeline, is closely docked with the flange of the water pipeline. Determine the flange specifications according to different pressure bearings and fasten with bolts to ensure the sealing performance with the water pipeline. The lever-type locking mechanism at the other end presses tightly against the male connector pipe 5 with a conical filter cartridge. Its structural design realizes rapid and firm connection, ensuring the stability of the split and detachable pipeline filter for the water pipeline in the entire water pipeline system.

[0027] The silicone rubber sealing ring 2 is installed inside the female flange 1 of the quick connector and is used for sealing between the female flange 1 of the quick connector and the male connector pipe 5 of the quick connector to prevent water leakage. The silicone rubber sealing ring 2 has good elasticity and sealing performance, and also has excellent performance in terms of temperature resistance, pressure resistance, and acid and alkali resistance.

[0028] The conical filter cartridge 3 is fixed on the male connector pipe 5 of the quick connector, forms a seal with the male connector pipe 5 of the quick connector through the polytetrafluoroethylene gasket 4, and is pressed and sealed with the silicone rubber sealing ring 2 through the lever-type locking mechanism of the female flange 1 of the quick connector, and is used to capture and filter impurities in the water. The conical filter cartridge 3 uses a porous filtering material, has high filtering efficiency and a long service life. The design of the conical filter cartridge 3 enables the water flow to fully contact the filtering material when passing through the filter cartridge, improving the filtering effect. And according to the needs of different particle sizes, flow rates, and media, the filter cartridge can be replaced.

[0029] The polytetrafluoroethylene gasket 4 is located outside the conical filter cartridge 3 and is closely attached to the male connector pipe 5 of the quick connector. At the same time, due to its chemical stability, it ensures that no corrosion occurs under various water quality conditions, thus maintaining the long-term stable operation of the filter.

[0030] The male quick connector pipe joint 5 is located behind the female quick connector flange 1. The conical filter cartridge 3 and the polytetrafluoroethylene gasket 4 are fixed at the front end of the male quick connector pipe joint 5. The male quick connector pipe joint 5 cooperates with the lever-type locking mechanism of the female quick connector flange 1, and relies on the silicone rubber sealing ring 2 to achieve sealing, and is connected to the outlet flange pipe 7 by the snap-type quick connection pipe clamp 6.

[0031] The snap-type quick connection pipe clamp 6 connects the male quick connector pipe joint 5 and the outlet flange pipe 7, and is used to stabilize the connection between the filter and the water pipe system. The inner side of the snap-type quick connection pipe clamp 6 is lined with a lip-shaped rubber ring structure, which has a good sealing effect. At the same time, it can appropriately compensate for the axial displacement and angular deviation of the water pipe. It is simpler to install and disassemble than flange and thread, ensuring the stability and convenience of the connection.

[0032] The outlet flange pipe 7 is connected to the snap-type quick connection pipe clamp 6 and serves as the outlet of the filter, and is used to convey the filtered water to the water-using equipment. The outlet flange pipe and the subsequent pipeline of the water pipe are connected by flanges.

[0033] Figure 1 As shown in the figure, one end of the female quick connector flange 1 is a connecting flange, which is bolted to the flange of the front-end pipeline to form a fixed end and does not need to be disassembled during subsequent use. A silicone rubber sealing ring 2 is installed inside the female quick connector flange 1 to ensure that the silicone rubber sealing ring 2 is closely attached to the female quick connector flange 1 to form a sealing interface. The conical filter cartridge 3 and the polytetrafluoroethylene gasket 4 are fixed on the male quick connector pipe joint 5 to jointly form a filter assembly. This filter assembly is tightly sealed with the silicone rubber sealing ring 2, and the male end of the male quick connector pipe joint 5 is locked and sealed with the female end of the female quick connector flange 1 through the lever-type locking mechanism of the female quick connector flange 1. The snap-type quick connection pipe clamp 6 tightly connects the male quick connector pipe joint 5 and the outlet flange pipe 7 through the lip-shaped rubber ring structure inside and the external quick clamping mechanism. The flange end of the outlet flange pipe 7 is fixed to the flange of the downstream pipeline by bolts.

[0034] The lever-type locking mechanism of the female quick connector flange 1 is locked with the groove at the male end of the male quick connector pipe joint 5 to achieve convenient disassembly and assembly.

[0035] Figure 1 、 Figure 2 As shown in the figure, the conical filter cartridge 3 and the polytetrafluoroethylene gasket 4 are fixed on the male quick connector pipe joint 5 to jointly form a filter assembly. This filter assembly is sealed by pressing the male end of the male quick connector pipe joint 5 against the silicone rubber sealing ring 2 embedded in the female quick connector flange 1, and quick disassembly and assembly are achieved through the lever-type locking mechanism of the female quick connector flange 1.

[0036] Figure 1 、 Figure 2, Figure 3 As shown, the snap - on quick - connection pipe clamp 6 is composed of an inner rubber - lined ring structure, two externally snap - fitting compression sheets, and compression screws. The flange end of the outlet flange pipe 7 is connected to the flange of the downstream water pipeline and does not need to be disassembled during normal use. The snap - on quick - connection pipe clamp 6 relies on the inner rubber - lined ring structure to achieve sealing, and fastens and connects the male adapter pipe 5 of the quick - connector and the outlet flange pipe 7 through the two externally snap - fitting compression sheets and compression screws.

[0037] The above has introduced in detail a split - type detachable pipeline filter for a water pipeline provided by the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
