Method and structure for preventing internal leakage of manual temperature adjusting water mixing valve

The invention discloses a method and a structure for preventing internal leakage of a manual temperature adjusting water mixing valve. Inner leakage is prevented by utilizing the non-return characteristic of one-way valves. According to the specific structure and connection, one-way valves are installed at the cold water inlet end and the hot water inlet end of the water mixing valve correspondingly in the water supply direction, and therefore water in a high-pressure pipeline is prevented from entering a low-pressure pipeline. In practice, the one-way valves and the manual temperature adjusting water mixing valve can be integrated into the internal leakage preventing manual temperature adjusting water mixing valve. According to the method and the structure for preventing internal leakage of the manual temperature adjusting water mixing valve, the structure is simple, work is reliable, the price is low, refitting is easy, very high application and popularization value is achieved, and wide market prospects ar
