Embodiment 1

[0028] refer to Figure 1~Figure 6 , an angle valve, comprising a metal shell 1, the shell 1 is embedded with a plastic liner 2 that meets environmental protection standards, and the plastic liner 2 is provided with a water inlet 201 corresponding to the shell 1 and Water outlet 202 , the plastic lining 2 covers the water passing part of the inner wall of the shell 1 , and the valve core 3 is installed on the plastic lining 2 . With the above-mentioned structure, water enters from the water inlet 201, flows through the valve core 3, and flows out from the water outlet 202. Since the plastic lining 2 covers the water-passing part of the inner wall of the casing 1, the water and the metal casing 1 are isolated to prevent the casing 1 from producing metal. The precipitates pollute the water, improve the water quality, meet the requirements of relevant standards, and meet the current people's pursuit of a green and environmentally friendly life.

Embodiment 2

[0034] refer to Figure 7~Figure 10 , this embodiment is basically the same as Embodiment 1, the difference is that: the outer wall of the water inlet end of the housing 1 is provided with a groove 101, and one end of the water inlet 201 of the plastic lining 2 extends outwards to cover the groove The slot 101 replaces the adapter nut 3 . Covering the groove 101 with the plastic liner 2 can make the connection between the plastic liner 2 and the shell 1 more stable, eliminate the gap between the two, and ensure that the plastic liner 2 covers the inner wall of the shell 1 too much. Water parts, prevent drinking water from contacting metal.

Abstract

The invention discloses an angle valve which comprises a metal shell. A plastic liner is embedded into the shell and provided with a water inlet and a water outlet corresponding to the shell, the plastic liner covers a water passing portion on the inner wall of the shell, and a valve spool is mounted on the plastic liner. Drinking water is isolated from contacting with the metal shell, and metal precipitates are prevented from polluting the drinking water.

Description

technical field [0001] The invention relates to an angle valve. Background technique [0002] Angle valve is a kind of valve. It is generally used on the water inlet pipe of washbasin, toilet water tank and water heater. The main functions of angle valve include: 1. To connect the inner and outer water outlets; 3. The function of the switch, if the faucet or valve leaks or fails, you can turn off the angle valve for maintenance or replacement without closing the main valve at home. Therefore, angle valves are essential bathroom accessories in general home decoration. At present, the angle valves used in the sanitary industry are generally made of metal materials in order to meet the relevant strength requirements. During use, the angle valves are in direct contact with drinking water, which brings some metal precipitates and causes certain pollution to the water quality. , does not meet the requirements of the relevant standards. Contents of the invention [0003] In or...
