Floor heating constant-temperature water mixing valve

Abstract

The invention relates to the field of jet propulsion devices, and discloses a floor heating constant-temperature water mixing valve, which comprises a main valve body, the two ends of the main valve body are connected with a cold water opening and a hot water opening correspondingly, a valve cavity is formed in the main valve body, and a first automatic adjusting mechanism is arranged in the valve cavity; the automatic adjusting mechanisms can automatically adjust the water inlet amount of hot water according to the mixed water temperature, so that the water temperature can be kept at a designated temperature, a manual adjusting mechanism is arranged on one side of the first automatic adjusting mechanism, and the manual adjusting mechanism can adjust the temperature kept by the automatic adjusting mechanism. According to the invention, through the mode of thermal expansion and cold contraction, the inlet and outlet mixing proportion of cold water and hot water can be automatically controlled, the size of the cold water inlet and hot water inlet is controlled according to the temperature of mixed water, and then the cold water and hot water flow is controlled, so that an automatic constant-temperature effect is achieved.

Description

technical field [0001] The invention relates to the technical field of a constant temperature water mixing valve, in particular to a floor heating constant temperature water mixing valve. Background technique [0002] With the improvement of living standards, people will also encounter some problems when enjoying the comfort brought by floor heating. Among them, when the temperature of cold and hot water changes, the heating temperature adjustment is unstable, and the constant temperature cannot be well controlled. Then there will be hot and cold situations, which will greatly reduce the comfort level, and is not conducive to energy saving. At the same time, because most thermostatic valves are electronically controlled, they cannot work when there is a power failure, which is inconvenient to use. Contents of the invention [0003] The invention provides a floor heating constant temperature water mixing valve, which can solve the above problems. [0004] The present inven...

[0002] With the improvement of living standards, people will also encounter some problems when enjoying the comfort brought by floor heating. Among them, when the temperature of cold and hot water changes, the heating temperature adjustment is unstable, and the constant temperature cannot be well controlled. Then there will be hot and cold situations, which will greatly reduce the comfort level, and is not conducive to energy saving. At the same time, because most thermostatic valves are electronically controlled, they cannot work when there is a power failure, and it is more inconvenient to use.
