Traps selection introduction
Steam trap in 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. 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 traps: classified as mechanical type, thermal type, thermal type. Mechanical trap: Mechanical type, also known as the float, is the use of condensed water and steam density difference, through the condensate level changes, so that the float lift valve to open or close to achieve the purpose of blocking steam drainage. Mechanical type of small degree of supercooling traps, free from pressure and temperature changes, the water that is row, no water heating equipment, heating equipment can achieve the best heat transfer efficiency. Maximum back pressure ratio of 80%, high quality workmanship, the production process is the ideal heating device steam trap. Mechanical traps have free float, free half float, lever float, inverted bucket and so on. Free Float Traps: Free float steam traps have a simple structure and only one stainless steel hollow float with finely ground moving parts. It is both a float and an opening and closing piece, with no wearing parts and a long service life. "YQ "Traps with Y series of automatic exhaust within the air device, very sensitive, automatic exhaust air, high quality work. Search Keyword: More Valve Technical Articles
