What is a thermostatic steam trap?

What type of element does a thermostatic steam trap use to sense temperature changes?

A thermostatic steam trap uses a thermostatic element, such as a bellows or a diaphragm, to sense the temperature of the steam.

Thermostatic Steam Trap Overview

A thermostatic steam trap operates by using a thermostatic element to sense temperature changes and open or close a valve accordingly. The thermostatic element can be a bellows or a diaphragm, which expands or contracts based on the temperature of the steam.

Functionality

When the temperature of the steam drops below the set point, the thermostatic element contracts and closes the valve. This prevents steam from passing through the trap, allowing condensate to be drained effectively.

Operation Mechanism

In the case of a thermostatic steam trap using a bellows as the thermostatic element, the bellows opens or closes the valve as the temperature of the steam changes. When the temperature decreases, the bellows contracts and closes the valve, stopping the flow of steam.

Advantages

Thermostatic steam traps are known for their reliability and ability to quickly respond to temperature changes in the steam system. They are efficient in removing condensate from the system while allowing steam to pass through effectively.
