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。 　　{dy}，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{zj0}状态，使设备内的凝结水不形成滞留，{zd0}限度地确保设备内的蒸汽空间，这样可经常保持{zg}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xx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。

Many current models of steam traps, but the working principle is the use of steam and condensation of water height, temperature, flow rate differences, through various agencies to achieve steam traps open and close, to waste gas drainage purposes. It has three main energy saving function. First, the rapid use of equipment to generate steam discharge condensate, so that the efficiency of steam heating equipment used to maintain the best condition, so that equipment does not form condensate within the stay to ensure maximum equipment within the steam room, this can often maintain the highest heating efficiency. Once the steam trap can not fully play its role as condensation water retention, not only the performance of steam using equipment was seriously affected, sometimes even complete paralysis of production equipment. Second, the rapid discharge when the device started and the temperature of air inside the condensate, thus shortening the warm-running time. Start the steam, the steam delivery pipe and the steam used inside the device are filled with air, if it does not exclude them, you can not into the steam. In addition, transmission lines and steam in the steam using equipment to steam temperature heating process, the condensate produced by the initial low temperature and quickly discharged to the normal operation of equipment in the short period of time, this is an important condition for improving production efficiency, in particular, intermittent production of the occasion, because shortened warm-up time, thus shortening the time each operation, the addition of the processing times, ultimately, increased productivity. Previously, when running in warm, first open the bypass valve to discharge the initial temperature of air and condensate, since the selection of the proper steam trap, can automatically discharge the initial air and initial temperature condensate, and save manpower. Third, reduce the consumption of steam trap their own steam. The so-called own steam consumption of steam traps, generally refers to steam leak, the steam trap is the action necessary steam amount and the sum of heat loss.
