自力式恒温混水阀外型类似一个4通水阀,有3个阀口,一个温度调节钮。3个阀口中有两个分别是冷热水进水口,另一个是恒温出水口。在出水口处装有一个热敏元件,利用感温元件的特性推动阀体内阀芯移动,封堵或开启冷、热水的进水口,在封堵冷水的同时开启热水。当温度调节旋钮设定某一 Self-temperature thermostatic mixing valve looks like a 4-way valve, there are three valve ports, a temperature control button. Two of the three ports are hot and cold water inlet, the other is the thermostatic water outlet. In the water outlet is equipped with a thermal element, the use of temperature characteristics of the components to promote the movement of the spool valve body, plugging or open cold, hot water inlet, blocking cold water at the same time open the hot water. When the temperature control knob to set a certain
