Title:
WATER MIXING VALVE FOR AUTOMATICALLY CUTTING OFF AT HIGH TEMPERATURE
Document Type and Number:
WIPO Patent Application WO/2023/236461
Kind Code:
A1
Abstract:
A water mixing valve for automatically cutting off at high temperature, comprising a valve body, a hot water joint arranged on the left side of the lower surface of the valve body, a cold water joint arranged on the right side of the lower surface of the valve body, and a water outlet joint arranged on the front side of the middle of the valve body. A water mixing cavity communicated with the water outlet joint is arranged in the middle of the valve body; the hot water joint is communicated with the water mixing cavity by means of a hot water hole, the cold water joint is communicated with the water mixing cavity by means of a cold water hole, and the hot water hole is lower than the cold water hole in position; an annular sealing step is arranged on the lower part of the water mixing cavity, and the sealing step is lower than the hot water hole in position; a temperature adjustment mechanism matching the water mixing cavity is arranged on the upper part of the water mixing cavity; a piston core is arranged in the water mixing cavity, and the outer peripheral surface of the piston core is attached to the inner wall of the water mixing cavity. According to the water mixing valve for automatically cutting off at high temperature in the present invention, hot water can be automatically cut off when cold water is suddenly closed, so that the situation that high-temperature hot water which has not been mixed with cold water directly flows out of the water outlet joint to cause scalding is effectively avoided, and potential safety hazards are effectively avoided.
