疏水阀的选型技巧

　　疏水阀的选型技巧：

　　1、倒吊桶疏水阀：

　　作为所有工艺负荷和蒸汽主管线疏水阀的，即需要对蒸汽疏水的场合。

　　2、浮球热静力疏水阀：

　　用于工艺疏水，尤其是在控制负荷3.5公斤以下（50psig）的应用场合或空气含量高、安装倒吊桶疏水阀有问题的场合。

　　3、平衡压力疏水阀：

　　用作不重要的伴热或加热系统。

　　4、双金属片热静力疏水阀：

　　用于伴热管线或加热系统低温或防霜工况。该类型的疏水阀可以大限度地利用凝结水中的显热或防止产品过热。其阀体为全不锈钢。

　　5、热动力圆盘疏水阀：

　　只要在先前经验证明其性能良好时，可作为倒吊桶疏水阀的替代产品，在压力为17公斤以下的蒸汽主管和伴热管上有限制地使用，或作为产品替换用于更高的蒸汽压力。因其能源效率低，使用寿命短，不推荐使用。

　　6、在热量要求不高的场合，用热静力疏水阀取代热动力圆盘疏水阀会提高节能效果，同时保证使用寿命。

　　7、机械疏水阀（即倒吊桶和浮球疏水阀）无论在凝结水负荷大或负荷小的情况下都可以保证蒸汽不含冷凝水，而热静力疏水阀在负荷增加的时候容易积聚凝结水。

The types of traps can maximize the use of the sensible heat of condensation of water to prevent overheating. Its body made ??of stainless steel. 5, thermodynamic disc trap: Previous experience proved its good performance, can be used as alternative to inverted bucket trap at a pressure of 17 kg of steam mains, and with heat pipe, limited use, or as a replacement for the higher vapor pressure. Because of its low energy efficiency, life is short, not recommended (and in the Huddersfield and Grangemouth factory are not allowed). Less demanding situations, the heat, thermostatic steam traps to replace the thermodynamic disc trap will increase energy savings, life assurance. 7, mechanical traps (ie, inverted bucket and float trap) both in the case of condensation of the water load large or small load to ensure that the steam does not contain a condensate, while the thermostatic steam traps in the load increases the accumulation of condensation Trap selection techniques: An inverted bucket trap: As the process load and steam mains trap of choice for all those in need on the occasion of the steam trap. 2, the float thermostatic steam traps: Used to process the hydrophobic, especially in the application of the control load of less than 3.5 kg (50 psig) or high air content, install the inverted bucket trap occasions. 3, the balanced pressure steam trap: As unimportant heating or heating system. 4, bimetal thermostatic steam traps: For heating pipes or heating system, low temperature or frost prevention conditions.
