Classification and Working Principle of Steam Trap With the continuous improvement of people’s awareness of environmental protection, energy conservation and emission reduction have become a hot topic of social concern. The trap is a kind of energy-saving equipment came into being under this background, it can reduce the system pressure, reduce the energy loss, for the enterprise to bring considerable energy-saving benefits. This paper will introduce and analyze the principle, type and selection of trap. First, the principle of steam trap Steam trap is an automatic control valve, the main role is in the steam pipeline and equipment, timely elimination of condensate to ensure the stable operation of the system. The working principle of the trap is based on the physical law – the principle of thermodynamics. When the steam passes through the pipe, its temperature is higher than the surrounding environment, so it will emit heat, and the temperature […]
