A quick-connect angle valve is similar to a ball valve, with its structure and characteristics modified from the latter. Unlike a ball valve, the outlet of an angle valve is at a 90-degree right angle to the inlet. Angle valves are also referred to as three-way valves, corner valves, or corner water valves. Currently, angle valves are typically used between faucets and metal pipes: the valve’s outlet is first connected to the metal pipe via threads, after which multiple layers of leak-proof sealing material are wrapped around the connection joint.

　　Over time, the threads become oxidized and the sealant layer deteriorates, leading to dripping. In addition, the installation of the sealant layer is complex and inefficient, while the valve stem and ball in conventional angle valves wear out after prolonged use, resulting in a short service life.

　　In view of the aforementioned problems in the prior art, those skilled in the art have provided a quick-connect angle valve that is simple to install, has a long service life, and offers excellent sealing performance. This quick-connect angle valve is implemented through the following technical solution: a quick-connect angle valve comprising a valve body, a valve stem, a ball, a first water inlet, and a second water inlet, wherein the first water inlet is arranged on the side wall of the valve body and the second water inlet is arranged at the bottom of the valve body. A hollow nylon sleeve is coaxially arranged inside the first water inlet, with open-type circlips positioned between both ends of the nylon sleeve and the nuts. The valve ball is provided with a through-hole extending toward the first water inlet, and at the position corresponding to the second water inlet there is a second through-hole extending into the interior of the valve ball and communicating with the interior of the second water inlet.

　　In the quick-connect angle valve, the outer end of the nut is provided with a flange that tapers radially toward the central axis of the water inlet. In the quick-connect angle valve, the outer end of the retaining clip is chamfered, and this chamfer is configured to abut against the inner wall of the cap flange. In the quick-connect angle valve, both ends of the peripheral wall of the nylon sleeve are chamfered, with the chamfers tapering radially toward the central axis of the water inlet. In the quick-connect angle valve, a valve cover is mounted on the top of the valve body and is threadedly engaged with the valve body. In the quick-connect angle valve, the water inlet is interference-fitted with the nylon sleeve. In the quick-connect angle valve, a rubber sealing washer is provided between the through-hole in the valve body and the nylon sleeve.

　　In the quick-connect angle valve, a stainless steel retaining ring is installed between the rubber gasket and the nylon sleeve inside the valve body to provide a sealing function and is connected to the rubber gasket. In the quick-connect angle valve, the valve body and the valve stem are sealed by multiple sealing rings.

　　Compared with the prior art, the aforementioned quick-connect angle valve has the following advantages:

　　1. In the quick-connect angle valve, the valve stem and valve ball are integrally formed, such that the valve ball rotates in tandem with the valve stem. This design eliminates the excessive wear caused by the separate configuration of the original valve ball and valve stem, thereby extending the service life of the valve.

　　2. The quick-connect angle valve is equipped with a nut and a split circlip. When connecting piping components, the nut is threaded onto the valve body and rotated to engage; the split circlip is then closed to secure the pipe, offering the advantages of quick connection and easy disassembly.

　　3. The quick-connect angle valve is equipped with a nylon sleeve. After the pipe fitting is inserted into the valve body, the nylon material—characterized by excellent toughness, a smooth surface, a low coefficient of friction, and outstanding wear and fatigue resistance—allows the split circlip to move closer toward the interior of the valve body as the nut is tightened. Consequently, the nylon sleeve can slide within the valve body, and the chamfers at both ends of the sleeve can flex inward to engage with the valve body and the pipe fitting, thereby achieving a sealing effect.
