Abstract

A constant temperature mixed valve core includes a fluid switch control unit and a thermostatic control unit, wherein, the fluid switching control unit is connected together with the thermostatic control unit through a temperature conditioning mechanism of the thermostatic control unit; the fluid switching control unit includes a shell of a determined internal area, a fixed lower ceramic chip arranged in the internal area and provided with a center trepanning and at least one grooving, and an upper ceramic chip arranged in the shell internal area, rotatable on the lower ceramic chip and provided with a center trepanning and at least one grooving; a temperature regulation mechanism perforates the center of the shell and combines with the upper ceramic chip to perform operations, drives the ceramic chip to move so that the grooving of the upper ceramic chip is supposed with the grooving of the lower ceramic chip to form a state that the outside water outlet is open. The fluid switching regulator control unit is used to control the mixed water that has been completely mixed evenly and reaches the setting temperature, adjusts the opening angle of the control switch to control the output water flow of the mixed water that has been completely mixed evenly and reaches the setting temperature and the open and shut of the water output, which has features of easy modulation and long service life.

Description

technical field

[0001] The invention relates to a valve core structure, in particular to a constant temperature mixing valve core used for mixing cold and hot water to let the water outlet temperature flow out at a constant temperature according to a set value. Background technique

[0002] Thermostatic mixing valves are well known and widely used in residential and commercial installations. The spools sold in large quantities in the world market that can provide constant temperature generally all control the flow size and the water outlet switch by controlling the cold and hot water inlets respectively. For this reason, their structures are more complicated and the cost is higher. No matter what kind of device it is, the mixing valve combines two water channels, mainly hot water and cold water channels, to form mixed water to pass through the water outlet device, such as a faucet or a shower for constant temperature water outlet. Although the emerging thermostatic mixing v...
