Problems solved by technology
After the metal casing is used for a long time, it is very easy to scale and block the valve body. When used in a highly corrosive liquid pipeline, the metal casing is easily corroded and affects the service life.
In addition, the processing of the metal shell has a lot to do with human factors, the process consistency is poor, the versatility is not good, and it is not suitable for mass promotion and use.

A water supply pipeline valve is composed of a casing (1), a thermo-sensitive element (2), a valve core (3), a cold water inlet (4), a hot water inlet (5) and a mixed water outlet (6), wherein the thermo-sensitive element (2) and the valve core (3) are installed inside the plastic casing (1), and the cold water inlet (4), the hot water inlet (5) and the mixed water outlet (6) are installed outside the plastic casing (1). The water supply pipeline valve is characterized in that the casing (1) is a double-layer plastic casing structure formed through secondary injection molding, a temperature-resisting pressure-resisting layer (101) is arranged inside the casing, and an electroplating casing layer (102) is arranged outside the casing. The water supply pipeline valve comprises a temperature regulating rotary button (7) which is installed at one end of the water supply pipeline valve away from the mixed water outlet (6). Compared with water supply pipeline valves with plastic casings in metal structures in the market, the cost of the water supply pipeline valve is reduced obviously. The plastic casing is good in processing technological consistency and generality, and batch production is facilitated.
Description
technical field [0001] The invention relates to the technical field of valve structure design and application, and in particular provides a water supply pipeline valve with a plastic shell. Background technique [0002] At present, most of the water supply pipeline valves on the market are made of metal shells and valve cores. Some water supply pipeline valves use metal shells and plastic valve cores, and their costs are relatively high. After the metal casing is used for a long time, it is very easy to scale and block the valve body. When used in a highly corrosive liquid pipeline, the metal casing is easily corroded and affects the service life. In addition, the processing of the metal shell has a lot to do with human factors, the process consistency is poor, the versatility is not good, and it is not suitable for mass promotion and use. The plastic parts are processed by injection molding, the consistency of the process is relatively good, and it is easy to realize large...
