The floor heating return water thermostatic control valve consists of a valve body and a manual temperature regulating handle, which are installed at the return end of the water collector and distributor. Its working principle is: the user turns the temperature regulating handle to a certain scale value to set the required temperature, and through the expansion and contraction of the temperature sensing driving element inside the valve body, the valve can be opened and closed according to the predetermined return water temperature, and the device can automatically regulate the water flow. The ground heating return water thermostatic control valve controls the change of the return water flow according to the temperature sensing of the return water, and the water supply flow also changes with the control of the return water flow, and the water supply temperature is constant. When the flow of return water decreases, the temperature of the room will decrease accordingly, and when the flow of return water increases, the temperature of the room will increase accordingly.
