Technical Field
[0001] This utility model relates to the field of valves, and in particular to a quick-connect angle valve. Background Technology
[0002] Currently, angle valves in China are typically installed using an in-wall method. This means the water pipe outlet is located inside the wall, with internal threads, while the angle valve inlet has external threads. Teflon tape is wrapped around the external thread at the inlet, and the connection is achieved by tightening the external thread to the internal thread. However, in North America, angle valves are installed with the water pipe outlet outside the wall, and this outlet does not have internal threads. Therefore, when Chinese angle valves are exported to North America for installation, an additional copper sleeve connector is required. This connector consists of a copper sleeve and a nut. The copper sleeve is drum-shaped, wider in the middle and narrower at the sides. During installation, the nut and copper cap are first threaded onto the water pipe, then the angle valve is inserted. The nut is then rotated towards the angle valve, causing it to push the copper cap and the inlet of the angle valve to clamp the water pipe, completing the installation. However, this installation method is more complex, and users usually need a wrench to tighten the nut, making it inconvenient. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings: A quick-connect angle valve includes an angle valve body 1 and a quick-connect connector. The angle valve body 1 and the quick-connect connector are detachably connected. If either the angle valve body or the quick-connect connector is damaged, it can be replaced separately, saving maintenance costs. The quick-connect connector includes a housing 2, an inner liner 3, an inner core 4, a retaining ring 5, and an O-ring 6. The housing 2 is hollow inside, and a partition ring 21 extends inward from the hollow housing. The lower part of the partition ring 21 is an angle valve connection part 23, which is used to connect the angle valve. The upper part of the partition ring 21 is a water pipe connection part 22, which is used for... The water pipe is connected, and the inner liner fitting 3 is placed on the separator ring 21 on one side of the water pipe connection part 22.

The fixing component 7 is provided with a retaining spring mounting groove 73. The retaining spring 5 is installed in the retaining spring mounting groove 73. The retaining spring 5 is used to fix the water pipe after installation to prevent the quick connector from being pulled out of the water pipe. An inner core 4 is provided between the retaining spring 5 and the fixing component 7. The inner diameter of the inner core 4 is larger than the inner diameter of the retaining spring 5. The inner core 4 is used to open the retaining spring 5 during disassembly to facilitate the removal of the quick connector and angle valve from the water pipe.
[0021] Furthermore, the retaining ring 5 includes a connecting ring portion 51 and a clamping portion 52. The connecting ring portion 51 is placed in the retaining ring mounting groove 73. The clamping portion 52 is inclined inward and downward. A plurality of elastic pieces 53 are arranged in a circular array on the clamping portion 52. When the water pipe is inserted, the water pipe is installed by spreading the elastic pieces along the inclined clamping portion 52. After installation, the spread elastic pieces will block the water pipe when it is pulled outward, preventing the quick connector from being pulled out of the water pipe.
