Which type of steam trap has no moving parts?

The type of steam trap that has no moving parts is indeed the continuous flow type. This design operates on a principle that allows condensate to flow out while preventing steam from escaping, all without the need for any mechanical movement. The continuous flow type typically relies on gravity or the natural flow of condensate to keep working efficiently.

In contrast, the other types of steam traps involve moving parts to function. For instance, float type traps use a floating mechanism to regulate the discharge of condensate based on its level, and thermodynamic traps rely on the principles of thermodynamics to create a pressure difference that opens and closes a valve rather than a mechanical part. Mechanical traps, as the name suggests, rely on mechanical components to operate, making them less suitable for environments where minimal maintenance is desired.

Understanding the design and operation of the continuous flow type steam trap highlights its advantage in situations where reliability and reduced maintenance interdependencies are crucial.
