quick-connect angle valve is similar to a ball valve, and its structure and characteristics are modified by the ball valve. Unlike the ball valve, the outlet of the angle valve is at a right angle of 90 degrees to the inlet. Angle valve is also called triangle valve, angle valve, angle water valve. The existing angle valve is usually used between the faucet and the metal pipe, because the water outlet of the angle valve and the metal pipe are first connected by threads, and then a plurality of leak-proof layers are wound around the connection port.

As the use time increases, the thread will be oxidized, the leak-proof layer will age, and water dripping will occur. In addition, the installation of the leak-proof layer is complicated and inefficient. At the same time, the valve stem and valve ball in the traditional angle valve will wear out after long-term use, and the service life is short.

In view of the above-mentioned problems in the prior art, technicians provide a quick-connect angle valve with simple installation, long service life and good sealing performance. The quick-connect angle valve is realized through the following technical solutions: a quick-connect angle valve, including a valve body, a valve stem, a ball, a water inlet and two water inlets, one water inlet is arranged on the side wall of the valve body, and the two water inlets The port is arranged at the bottom of the valve body. A hollow nylon sleeve is coaxially arranged in a water inlet, an open circlip is arranged between the two ends of the nylon sleeve and the nut, and the valve ball is provided with a through hole extending toward the first water inlet, corresponding to the second water inlet The position is provided with two through holes extending toward the inside of the valve ball and communicating with the inside of the second water inlet.

In the quick-connect angle valve, the outer end of the nut is provided with an edge, which decreases radially towards the central axis of a water inlet. In the quick-connect angle valve, the outer end of the opening circlip is provided with a chamfer, and the chamfer is attached to the inner wall of the brim corresponding to the inner wall of the brim. In the quick-connect angle valve, two chamfers are provided at both ends of the peripheral wall of the nylon sleeve, and the two chamfers decrease radially towards the central axis direction of a water inlet. In the quick-connect angle valve, the top of the valve body is provided with a valve cover, and the valve cover is connected with the valve body in a threaded manner. In the quick connect angle valve, a water inlet is interference fit with the nylon sleeve. In the quick-connect angle valve, a sealing rubber gasket is arranged between a through hole in the valve body and the nylon sleeve.

In the quick-connect angle valve, a stainless steel circlip connected with the rubber gasket is arranged between the rubber gasket and the nylon sleeve in the valve body. 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 above-mentioned quick-connect angle valve has the following advantages:

1. The valve stem and the valve ball in the quick-connect angle valve are integrally formed, and the valve ball rotates with the valve stem, which solves the problem of excessive wear caused by the separate setting of the original valve ball and the valve stem, and has the advantage of prolonging its service life;

2. The quick-connect angle valve is provided with nut and split snap spring. When connecting the pipe fittings, the nut rotates with the thread on the valve body, and the opening of the split circlip is closed to fix the pipe fittings, which has the advantages of quick connection and convenient disassembly.

3, the quick-connect angle valve is provided with a nylon sleeve. After the pipe fitting is inserted into the valve body, because the nylon material has the advantages of good toughness, smooth surface, low friction coefficient, outstanding wear resistance and fatigue resistance, as the nut is screwed in, the opening circlip moves closer to the inside of the valve body. The nylon sleeve can move in the valve body, and the chamfers at both ends of the nylon sleeve can be bent into the valve body to collide with the pipe fitting to play a sealing role. 17
