Steam traps are only required for the functional use of steam traps and for devices that utilize steam. Condensation water is sure to be produced in such equipment, and condensate is a detrimental fluid, mixed with air and other non-condensable gases, which can cause equipment failure and performance degradation. In principle, the trap is fully open or fully closed, that is, open, close action. Depending on the type, there may be two types of continuous discharge and intermittent discharge. 1, you can rule out all the condensate water anywhere in the steam system. Steam traps must be capable of high delivery, accurately exclude the use of steam piping equipment, heat exchangers and other major equipment and steam system any part of the condensate generated. 2, can discharge air and condensate at the same time. The air mixed into the steam plant was initially mixed with the steam and was not separated until the steam formed water. It creates an air layer on the heat transfer surface of the steam-using equipment, severely affecting heat conduction and must therefore be vented. 3, for a wide range of pressure. For traps, if the pressure changes slightly its performance is affected, or even stop the action is not acceptable, in which case its performance is not affected, and can adapt to any pressure. At the same time require the steam trap to allow greater back pressure. 4, easy maintenance and repair. This requirement is related to the structure of the trap. Trap requires a simple structure, fewer moving parts. In order to make the valve action parts do not produce stress, the day should choose the appropriate materials, more importantly, its structure should be easy to process. In short, steam traps in the management should not require full-time staff to carry out regular maintenance work, that is to reduce maintenance costs. 5, high practicality. Traps should be small, light weight, high life expectancy, low prices, and not due to air or steam barriers and loss of drainage capacity, the occurrence of air blocking and steam locks and other accidents.
