Introduction and Application of High Pressure Steam Traps

High-pressure steam trap is used in high-pressure pipe network and equipment, can automatically discharge condensate, air and other non-condensable gas, and block water vapor leakage valve. According to the different working principle of high-pressure steam trap, steam trap can be turned into the following three types: Mechanical type: Rely on high-pressure steam trap condensate level changes in water and action, including: 1, Float: float closed Hollow sphere up float type: the float is open upward barrel open downward Float: the float is open downward barrel 2, the thermal static type: relying on changes in liquid temperature and action, including: bimetallic : Sensitive to the original bimetal pressure type: sensitive to the original bellows or ink cartridges, filled with volatile liquid inside 3, thermodynamic type: relying on the thermodynamic properties of the liquid changes. Disc type: Due to the same pressure, the flow rate of liquid and gas are different, resulting in different dynamic and static pressure to actuate the disc valve pulse: Due to the different temperatures of the condensate through the two series in series orifice Plate, sitting in the bipolar orifice between the different pressures, driving the valve action. Structure and working principle of high-pressure steam trap: Steam trap in the steam heating system to play the role of gas drainage, select the appropriate trap, the steam heating equipment to achieve maximum efficiency. In order to achieve the best results, we must conduct a comprehensive understanding of the performance of various types of traps, features. This type of valve in the pipeline should be generally horizontal installation. Trap a lot of varieties, each with different properties. The choice of traps, the first choice should be its characteristics to meet the best operation of steam heating equipment, and then consider other objective conditions, so you need to select the trap is correct and effective. Traps to be able to "identify" steam and condensate in order to play the role of gas blocking drainage. "Identifying" steam and condensate is based on three principles: density difference, temperature difference and phase transition. So according to three principles to create three types of trap: classified as mechanical type, thermal type, thermal type.
