进口内螺纹疏水阀工作原理：
本疏水阀是利用热动力学特性，当凝结水排流较低时会发生第二次蒸发，并在粘度、密封等方面与蒸汽方面存在差异驱动启闭件。 
进口内螺纹疏水阀结构简单,价格低,动作可靠.漏气率<3%,不受压力波动的影响,压力范围大.由于密封面不锈钢，使用寿命高
-type disc type steam trap works:
The trap is the use of thermal dynamics, when the condensate drain is low, evaporation will occur the second time, and viscosity, sealing and so there are differences with the steam-driven hoist pieces.
thermal power disc-type steam trap structure is simple, low cost, reliable action. Leakage rate of <3%, free from pressure fluctuations, pressure range due to the sealing surface of stainless steel, service life than similar

结构特点：
1、带蒸汽或空气保温装置，不受环境温度影响，减少动作频率，延长寿命。
2、备有过滤器和排污。
3、该阀动作灵敏可靠，排水量大。

W-type disc type steam trap structural characteristics:
1, with steam or air heat unit, from ambient temperature to reduce the operating frequency and prolong life.
2, with filters and sewage.
3, the sensitive and reliable valve action, a large displacement.
