Selecting the trap requires accurate and unobstructed steam-blocking drainage, high sensitivity, improved steam utilization, no leakage of steam, reliable working performance, high back pressure rate, long service life and convenient maintenance are the preferred conditions.
1. On high temperature and high pressure superheated steam lines and equipment, special steam traps for superheated steam should be used.
The superheated steam trap can separate the high temperature condensed water generated when the superheated steam disappears under the severe conditions of high temperature, high pressure and small load. The disc type steam heat preservation type steam trap uses the pipeline steam to heat the main steam chamber of the steam trap, and has an advanced structure. In the case of no condensed water, the steam trap is tightly closed, the working quality is high, the service life is long, and the high pressure is overheated. Steam special trap.
Second, in the production process of heat exchange equipment, drying room, rapid heat exchanger, distillation equipment, etc. need to quickly heat up, do not allow the production of heating equipment with condensed water, should use mechanical traps.
Mechanical traps are not affected by changes in operating temperature and pressure. Water is discharged, and the degree of subcooling is small. There is no water in the heating equipment, which can make the heating equipment reach the working temperature. Among them, the structure of the free float type steam trap is advanced and very sensitive. The small degree of subcooling of the Zui is 0 °C, and it can discharge the saturated temperature condensed water without steam leakage. The advantages are many, which can make the heating equipment reach the work efficiency. It is the ideal steam trap for the production process heating equipment.
Third, in steam pipelines, heat tracing pipelines, small heating equipment, heating equipment, steam equipment with low temperature requirements, thermostatic traps should be used.
The thermostatic trap has a large degree of subcooling and a low condensing water temperature, which can fully utilize the sensible heat of the high temperature condensed water, and the energy saving effect is good. Among them, the structure of the bell-type steam trap is advanced, no need to be manually adjusted, very sensitive, and the two types of membranes with 15°C and 30°C are available for selection. It is not afraid of freezing, small size, and can be installed at any position. It can repair and replace the valve core on the pipeline, saves money and labor, has long service life and wide application range. It is a boutique of thermostatic steam traps.
