Steam trap function in steam heating system

The steam trap plays a role in blocking the steam and water in the steam heating system. Selecting an appropriate trap can make the steam heating equipment achieve the highest working efficiency. In order to achieve the best results, we must fully understand the performance and characteristics of various types of traps.

There are many varieties of steam traps, each with different performance. When choosing a trap, Gui Long thinks that its characteristics should be selected to meet the optimal operation of the steam heating equipment before considering other objective conditions, so that the trap you need is correct and effective.

Traps must be able to "recognize" steam and condensate before they act as a barrier to steam. The "identification" of steam and condensate is based on three principles: density difference, temperature difference and phase change. Thus, three types of traps were manufactured based on three principles: classified as mechanical, thermostatic, and thermodynamic.

The mechanical type is also called float type. It uses the density difference between condensate and steam. By changing the liquid level of condensate, the float lifts the valve flap to open or close to achieve the purpose of blocking the steam discharge. Mechanical type traps have a low degree of undercooling, and are not affected by changes in working pressure and temperature. There is water and rows, and there is no water in the heating equipment, which enables the heating equipment to achieve the best heat exchange efficiency. With a maximum back pressure of 80% and high work quality, it is the ideal trap for heating equipment in the production process.
