A valve core ceramic chip group structure with precise temperature adjustment

Abstract

The invention discloses a valve element ceramic chip set structure with the temperature capable of being precisely adjusted. The valve element ceramic piece set structure with the temperature capable of being precisely adjusted comprises an upper ceramic chip and a lower ceramic chip matched with the upper ceramic chip; the upper end face of the lower ceramic chip is provided with a water mixing cavity in a sinking manner; the portions, on the two sides of the water mixing cavity, of the lower ceramic chip are symmetrically provided with a cold water inlet and a hot water inlet; the water mixing cavity is provided with a mixed water outlet; the lower end face of the upper ceramic chip is symmetrically provided with a crescent cold water temperature adjusting groove and a crescent hot water temperature adjusting groove; the cold water temperature adjusting groove is arranged at the position of the cold water inlet in a striding manner, and the hot water temperature adjusting groove is arranged at the position of the hot water inlet in a striding manner; and the side, adjacently connected with the hot water temperature adjusting groove, of the cold water temperature adjusting groove is gradually shrunk, and that is to say, the width of a gradually-shrunk groove opening is smaller than the caliber of the water inlets. The water outflow switch-on and switch-off and the water outflow flow of cold water and hot water are controlled by adjusting the rotating angle of the upper ceramic chip so that precise temperature adjustment can be achieved.

Description

technical field [0001] The invention relates to a shower device assembly, in particular to a ceramic sheet group structure of a valve core which can control the ratio of cold and hot water to realize precise temperature adjustment. Background technique [0002] Most of the existing equalizing pressure valves control the water intake and mixing ratio of cold and hot water entering the equalizing pressure valve for mixing by adjusting the size of the cold water outlet and the hot water outlet, thereby achieving the effect of controlling the temperature of the mixed water. [0003] However, the existing equalizing pressure valve cannot realize the function of precise temperature adjustment within a specified temperature range, and cannot perform stable and uniform temperature adjustment. Contents of the invention [0004] The purpose of the present invention is to provide a pressure balancing valve with simple structure and accurate temperature adjustment. [0005] To achiev...
