原文：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首选，即所有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最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（而且，在Huddersfield和Grangemouth工厂不允许使用）。　　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。

译文： Trap selection techniques: 1, the inverted bucket trap: As head of all process lines and steam trap loads of choice, namely the need for steam trap all occasions. 2, Float Thermostatic Traps: For hydrophobic process, especially in the control load 3.5 kg the following (50psig) or for applications where high air content, installing the bucket trap the occasion in question. 3, the equilibrium pressure trap: As unimportant or heating systems with heat. 4, Bimetal Thermostatic Traps: Used with low-temperature heat pipes or heating system or frost conditions. The type of trap can maximize the use of the sensible heat of condensation of water or to prevent overheating. The valve body is stainless steel. 5, thermodynamic disc trap: Previous experience has shown that as long as its good performance, the inverted bucket trap can be used as an alternative, the pressure of 17 kg of steam heat pipe on the head and with limited use, or as a replacement product for a higher vapor pressure. Its energy efficiency, life is short, not recommended (and, in Huddersfield and Grangemouth plant is not allowed). 6, in the heat less demanding situations, replace the trap with hot static thermodynamic disc trap will increase energy savings, while ensuring life. 7, mechanical traps (ie, inverted bucket and float traps) in terms of condensate load large or small case load can be guaranteed without the steam condensate, and thermostatic trap when the load increased accumulation of condensation of water.
