Specifically, the valve body 10 of the present embodiment may be pre-installed on a pipeline, and the valve core assembly 20 and the first joint assembly 30 are respectively installed on the valve body 10, and after the subsequent second joint assembly 40 is connected with a water inlet hose of a faucet, a toilet, etc., the second joint assembly 40 is connected to the first joint assembly 30, so that complicated installation operation in a narrow space is avoided, and the installation is convenient. The second joint assembly 40 of the present embodiment can rotate 360 ° with respect to the first joint assembly 30, so that the water outlet direction can be adjusted according to the requirements of the user.

Referring to fig. 1 and 2, the valve body 10 is a generally T-shaped pipe structure, and includes a water inlet end 11, a water outlet end 12, and an adjusting end 13, wherein the adjusting end 13 is located between the water inlet end 11 and the water outlet end 12. The water inlet end 11 may include a water inlet to allow water flow into the valve body 10. Specifically, the water inlet end 11 may be in communication with a tap water pipe. The water outlet end 12 is opposite to the water inlet end 11, and the water outlet end 12 may include a water outlet so that water flows out of the valve body 10. The adjusting end 13 can be used for adjusting the water flow, such as the cut-off or the on of the water flow or the size of the water flow.

The water outlet end 12 includes an inner peripheral surface 121, a first outer peripheral surface 123 and a second outer peripheral surface 125, the outer diameter of the second outer peripheral surface 125 is larger than the outer diameter of the first outer peripheral surface 123, and the second outer peripheral surface 125 is close to the water inlet end 11 relative to the first outer peripheral surface 123, so that the outer surface of the water outlet end 12 is approximately stepped. The inner circumferential surface 121 may be used to mount the check valve 31, and both the first outer circumferential surface 123 and the second outer circumferential surface 125 may be used to mount the second joint assembly 40.

The at least one sealing ring 32 is sleeved on the first outer circumferential surface 123 of the water outlet end 12, so that water can be prevented from flowing out from the gap between the second joint assembly 40 and the water outlet end 12, the first joint assembly 30 can be in interference fit with the second joint assembly 40, and the installation stability of the second joint assembly 40 is enhanced. In this embodiment, the at least one sealing ring 32 is two sealing rings 32, and the two sealing rings 32 are disposed at intervals. In other embodiments, the number of the sealing rings 32 may be one, three or four, and may be specifically set according to practical situations, so as to satisfy the waterproof and interference fit effects.

Referring to fig. 2 and 3, the check valve 31 is installed in the water flow passage 127 and on the inner circumferential surface 121 for controlling the on or off of the water flow at the water outlet end 12. So that the second water outlet connector assembly 40 is disconnected from the first connector assembly 30 by a person or accident, the check valve 31 is closed, thereby closing the water source, preventing the waste of the water source and the influence on the installer.

In this embodiment, the check valve 31 includes a fixed assembly 310, a movable assembly 313, an elastic member 315, a first waterproof ring 317 and a second waterproof ring 319. The fixed assembly 310 is fixedly mounted to the water outlet end 12 and cooperates with the movable assembly 313. The securing assembly 310 includes a first housing 311 and a second housing 312 that are nested together.

The movable assembly 313 is movably installed in the first water passage 3112 to open or close the water port 3122. Specifically, an elastic member 315 is installed between the movable assembly 313 and the first housing 311, and a restoring force of the elastic member 315 when deformed may push the movable assembly 313 to move, so that the movable assembly 313 may move in a direction approaching the first housing 311 when pushed, thereby opening the water passing port 3122, and the check valve 31 is in an open state. When the pushing force acting on the movable assembly 313 disappears, the movable assembly 313 can move away from the first housing 311 and abut against the second housing 312 due to the recovery of the elastic member 315, so as to close the water passing port 3122, and the check valve 31 is in a closed state. In this embodiment, the pushing force is from the ejector 41 of the second joint assembly 40.

The first waterproof ring 317 is sleeved on the movable assembly 313, and is used for being attached to the second housing 312 when the movable assembly 313 moves away from the first housing 311, so as to form a seal against the water passing opening 3122.

The angle valve of claim 1, wherein the non-return valve comprises a fixed assembly and a movable assembly that are mated, the fixed assembly being fixedly mounted to the water outlet end; when the second joint component is nested and installed on the first joint component, the ejector acts on the movable component, so that the movable component moves from a first position to a second position relative to the fixed component, and the check valve is in an open state; when the second joint component is separated from the first joint component, the ejection piece is separated from the movable component, so that the movable component moves from the second position to the first position relative to the fixed component, and the check valve returns to the closed state.

4. The angle valve of claim 3, wherein the fixed assembly comprises a first housing and a second housing that are nested and mated, the first housing defines a first water passage, the second housing defines a water passage, the first water passage communicates with the second connector assembly via the water passage, and the movable assembly is movably mounted to the first water passage to open or close the water passage.

5. The angle valve of claim 1, wherein the second connector assembly further comprises a water outlet connector and a ferrule, the water outlet connector is sleeved on the water outlet end, and the ferrule is sleeved on the water outlet connector and the water outlet end and is embedded in the water outlet end.

6. The angle valve of claim 5, wherein the second fitting assembly further comprises a fastening sleeve that fits over the ferrule and the water outlet fitting.

7. The angle valve of claim 5, wherein the second joint assembly further comprises a filter screen mounted within the outlet joint.

8. The angle valve of claim 5, wherein the water outlet fitting comprises a first fitting end and a second fitting end, the first fitting end and the second fitting end extending in different directions, the first fitting end being nested at the water outlet end and located between the water outlet end and the ferrule, the second fitting end being configured to mount a water outlet pipe; the first joint assembly further comprises at least one sealing ring sleeved on the water outlet end and located between the water outlet end and the first joint end.

9. The angle valve of claim 8, wherein the water outlet end comprises an inner peripheral surface, a first outer peripheral surface and a second outer peripheral surface, the second outer peripheral surface has an outer diameter greater than the outer diameter of the first outer peripheral surface, the second outer peripheral surface is provided with an annular clamping groove, the non-return valve is mounted on the inner peripheral surface, the first connector end comprises a connector inner surface and a connector outer surface which are opposite to each other, the connector inner surface is in contact with the first outer peripheral surface, the connector outer surface and the second outer peripheral surface are both in contact with the clamping sleeve, the clamping sleeve is provided with an annular protrusion matched with the annular clamping groove, and the annular protrusion is clamped in the annular clamping groove.

10. The angle valve of claim 1, wherein the valve core assembly comprises a valve core, a hand wheel and a tooth sleeve, the valve core is used for adjusting water flow from the water inlet end to the water outlet end, the tooth sleeve is clamped with the valve core, the hand wheel is fixedly connected with the tooth sleeve, and the hand wheel drives the tooth sleeve when rotating, so that the valve core is adjusted.
