Thermostatic Bimetallic

A steam trap that uses the temperature difference between steam and condensed water to discharge condensed water at a set temperature through the characteristics of the internal temperature sensing element (bimetallic or diaphragm).
The main component of the thermostatic trap is a bimetallic strip with different expansion coefficients (or a diaphragm filled with a liquid with a vaporization temperature lower than the saturation temperature of water) as a temperature sensing element, which is heated and deformed as the steam temperature rises and falls to control the opening and closing of the valve.
Thermostatic traps have a wide range of uses and are suitable for superheated steam pipelines, steam heating pipelines, equipment insulation, domestic heating, outdoor low-temperature environments, and heating equipment that allows the storage of high-temperature condensed water.

Working principle

1: At the beginning of operation, the bimetallic strip is flat, the valve disc and the valve seat are completely separated, and the air and low-temperature condensate are quickly discharged.	2: With the arrival of high-temperature condensate, the bimetallic strip is gradually bent by heat, driving the main lever and the valve disc to move closer to the valve seat.	3: When the temperature of the condensate continues to rise and reaches the set temperature, the valve disc and the valve seat are completely sealed and closed, and then the bimetallic strip automatically adjusts to open or close with the change of the temperature of the condensate.
