[0022] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0023] Reference Figure 1-2, what is disclosed in the embodiments of the present utility model is an improved angle valve, which includes a valve body 1, a water inlet pipe provided on the valve body 1, and a water outlet pipe horizontally provided on the valve body 1, an inner valve core seat 2 and an inner water inlet pipe 4 made of non-metal. A valve core chamber 3 is provided on the valve body 1. The inner valve core seat 2 is provided with an inner valve core chamber 3 for placing the valve core. The inner valve core seat 2 is arranged in the inner valve core chamber 3. The inner valve core chamber 3 is communicated with the inner water inlet pipe 4. The inner valve core seat 2 and the inner water outlet pipe 5 are connected by a first connecting device. The inner water outlet pipe 5 made of non-metal is penetrated in the water outlet pipe. The inner water outlet pipe 5 is communicated with the inner valve core chamber 3. A water outlet sealing ring 9 is arranged between the inner water outlet pipe 5 and the inner valve core seat 2. A water outlet sealing groove is opened between the inner valve core seat 2 and the water outlet pipe. The water outlet sealing ring 9 is arranged in the water outlet sealing groove. Both ends of the water outlet sealing ring 9 are respectively resisted against the inner valve core seat 2 and the inner water outlet pipe 5. The inner water outlet pipe 5 and the water outlet pipe are connected by threads.

[0024] Specifically, the first connecting device includes a first connecting pipe 6 integrally formed on the inner valve core seat 2 and a water inlet sealing ring 7. One end of the first connecting pipe 6 is communicated with the inner water inlet pipe 4. The other end of the first connecting pipe 6 is communicated with the inner valve core chamber 3. The first connecting pipe 6 and the inner water inlet pipe 4 are connected by threads. A sealing ring 8 capable of allowing water flow to pass through is arranged around the inner wall of the water inlet pipe. The water inlet sealing ring 7 is arranged on the sealing ring 8. The end of the first connecting pipe 6 is resisted against the water inlet sealing ring 7.

[0025] Preferably, the inner water inlet pipe 4, the inner water outlet pipe 5, the first connecting pipe 6 and the inner valve core seat 2 are made of plastic or ceramic or glass. In this angle valve, it is made of plastic.

[0026] Among them, when the angle valve is in use, water flows in from the inner water inlet pipe 4, flows in the inner water inlet pipe 4, then passes through the first connecting pipe 6, then enters the inner valve core chamber 3, and then passes through the inner water outlet pipe 5. Since the water passages passed through are all made of plastic, no metal will be precipitated into the water, avoiding the excessive heavy metals in the water, eliminating lead pollution, and being beneficial to green and healthy use and green and healthy drinking water.

[0027] When assembling the angle valve, the water inlet sealing ring 7 is placed at the position of the sealing ring 8, and then the inner water inlet pipe 4 and the inner valve core seat 2 are connected by threads. Then the water outlet sealing ring 9 is arranged in the water outlet sealing groove, and then the inner water outlet pipe 5 is inserted and thread-connected with the valve body 1, so that the inner water outlet sealing ring 9 is resisted against the inner valve core seat 2, and the installation can be completed. It is simple and convenient, which is beneficial to production and manufacturing.

[0028] In order to further facilitate installation, a first limiting platform 10 is wound around the upper part of the inner valve core seat 2, and the first limiting platform 10 abuts against the end of the valve body 1. A second limiting platform 12 is provided on the inner water inlet pipe 4, and the second limiting platform 12 abuts against the end of the water inlet pipe. A third limiting platform 11 is provided on the inner water outlet pipe 5, and the third limiting platform 11 abuts against the water outlet pipe. The positions of the inner valve core seat 2, the inner water inlet pipe 4 and the inner water outlet pipe 5 can be limited by the first limiting platform 10, the second limiting platform 12 and the third limiting platform 11, so that over-assembly and damage will not occur, thus enabling the staff to assemble better.
