The working principle of the steam traps and three energy-saving role Steam trap model, but its working principle is the height of the steam and condensate, the difference of temperature, flow rate, through various agencies to achieve the opening and closing of the steam trap and achieve the purpose of waste gas drainage. There are three major role in energy conservation. First, the rapid discharge of the condensate within the steam using the device, so that the heating efficiency of the steam equipment in top condition, not the formation of retention, to ensure maximum equipment within the vapor space of the condensate inside the device, so that one can always maintain the highest heating efficiency. Once the steam trap can not fully play a role not only steam equipment performance to be greatly affected, due to the condensation of water retention, and sometimes even completely paralyzed production equipment. Second, the rapid discharge began to start the equipment inside air and cold condensate, thus shortening the warm-up operation. The start of steam, the steam distribution piping and steam use within the device are filled with air, if it does not exclude them, it can not be fed into the steam. In addition, in the steam distribution piping and steam use equipment to heat up to steam temperature, the initial low temperature condensate also excreted rapidly from the device to achieve normal operation in a short period of time, which is an important condition to improve production efficiency, batch production of the occasion, a warm-up time is shortened, shortened each job due to the increased processing times, and ultimately increase the yield. Previously, in the warm-up operation, first open the bypass valve to discharge the initial air and low temperature condensate, the selection of the proper steam trap can automatically discharge the initial air and initial low-temperature condensate, but also save on labor. Third, to reduce the steam consumption of steam traps. So-called steam trap steam consumption, generally refers to steam leaks, steam trap action requires the amount of steam and cooling loss.

蒸汽疏水阀的工作原理及三个节能作用　目前的蒸汽疏水阀型号很多，但其工作原理都是利用蒸汽和凝结水的高度、温度、流速的差异，通过各种机构来实现蒸汽疏水阀的启闭，达到阻汽排水的目的。它主要有三个节能作用。第一，迅速排出蒸汽使用设备内产生的凝结水，使蒸汽使用设备的加热效率保持在最佳状态，使设备内的凝结水不形成滞留，最大限度地确保设备内的蒸汽空间，这样可经常保持最高的加热效率。一旦蒸汽疏水阀不能充分的发挥作用，由于凝结水的滞留，不仅蒸汽使用设备的性能受到很大的影响，有时甚至使生产设备完全陷于瘫痪。第二，迅速排出开始启动时设备内的空气和低温凝结水，从而缩短预热运转时间。开始通汽时，蒸汽输送管路和蒸汽使用设备内部都充满了空气，如不将它们排除，就无法送入蒸汽。此外，在蒸汽输送管路和蒸汽使用设备升温达到蒸汽温度的过程中，所产生的初期低温凝结水也要迅速排出，使设备在短时间内实现正常运转，这是提高生产效率的重要条件，特别是间歇生产的场合，由于缩短了预热时间，也就缩短了每次的作业时间，由于增加了处理次数，最终可增加产量。以前，在预热运转时，先开启旁通阀来排放初期空气和低温凝结水，现在由于选用了恰当的蒸汽疏水阀，既可自动排出初期空气和初期低温凝结水，又可节省人力。第三，降低蒸汽疏水阀自身的蒸汽消耗量。所谓蒸汽疏水阀自身的蒸汽消耗量，一般是指蒸汽泄漏而言，是蒸汽疏水阀动作需要的蒸汽量和散热损失量之和。
