Steam trap valve use range and selection method introduction

The steam trap can quickly eliminate the generated condensate; prevent steam leakage, prevent the use of steam equipment, prevent corrosion of steam from using the inside of the equipment, and prevent damage to the steam equipment. This article mainly introduces the scope of use and selection of steam traps:
1) The structure and principle of various types of steam traps are different. The type of trap should be distinguished. The pressure difference between the inlet and outlet of the steam trap should be determined according to the actual working conditions, and then according to the steam heating equipment, it may be generated during normal operation. The amount of condensed water is multiplied by the selected correction factor K and then selected against the displacement of the steam trap.
2) In the condensate recovery system, if the condensed water is recovered by the working back pressure, a steam trap with a high back pressure ratio (such as a mechanical steam trap) should be used; when the steam equipment is required, no condensate should be accumulated. When using a steam trap (such as a float steam trap) that continuously discharges saturated condensate, in a condensate recovery system, the steam equipment requires both discharge of saturated condensate and timely elimination of non-condensable gas. Should use a steam trap that can discharge saturated water in parallel with the exhaust device or a steam trap with both drainage and exhaust functions (such as thermostatic steam trap); when working with steam equipment When the pressure fluctuates frequently, a steam trap that does not require adjustment of the working pressure should be used.
3) The nominal pressure and working temperature of the steam trap should be greater than or equal to the maximum working pressure and maximum working temperature of the steam pipeline and the steam equipment.
4) When the drainage capacity of a steam trap cannot meet the requirements, several steam traps can be installed in parallel.
5), bypass pipe and bypass valve can be set for easy maintenance.
