Abstract
A thermostatic valve, including: a pressure relief ring capable of moving up and down and disposed in a valve body cavity. In normal conditions, the pressure relief ring is abutted against the outer edge of a first valve seat via a spring. An internal channel capable of being opened or closed via up and down movement of the pressure relief ring is further provided in the valve body cavity; when the pressure of a fluid in the thermostatic valve is excessive, the fluid can drive the pressure relief ring to compress the spring, such that the internal channel is in communication with a third interface to realize simultaneous communication with a first flow channel and a third flow channel.
