          1.根据实际使用工况确定蒸汽疏水阀的入口与出口的压差。日标阀门蒸汽疏水阀的入口压力是指由于蒸汽压力的波动或温度调剂阀的节流，蒸汽疏水阀入口处的最低工作压力；蒸汽疏水阀的出口压力是指蒸汽疏水阀后可能形成的最高工作背压，当排入大气时，实际压差按蒸汽疏水阀入口压力决定。

     　　2.根据蒸汽供热设备在正常工作时产生的英标阀门凝结水量，乘以选用修正系数k，然后按照蒸汽疏水阀的排水量进行选择。

     　　3.凝结水量可以用以下方法计算： 　　(1)管线运行时产生的凝结水量Q=q0L(1-Z/%)(kg/h),此公式中： 　　　　Q：凝结水量(kg/h) 　　　　q0：光管产生的凝结水量德标阀门(kg/h) 　　　　L：疏水点之间的距离(m) 　　　　Z：保温效率(%) 　　(2)蒸汽加热设备运行时产v生的凝结水量Q=VrC△T/Ht，此公式中： 　　　　Q：凝结水量(kg/h) 　　　　V：被加热物体的体积(m3) 　　　　r：被加热物体的密度(kg/ m3) 　　　　C：液体的比热美标阀门(kcal/kg.OC) 　　　　△T：液体温升(OC) 　　　　H：蒸汽潜热(kcal/kg) 　　　　t：加热时间

     　　4.各种类型的蒸汽疏水阀结构及原理有所不同，性能液不尽相同，在选用时可根据不同的使用场合，选择不同的蒸汽疏水阀

       1. According to the actual condition of steam traps to determine the pressure difference between inlet and outlet. Steam trap Ball Valvesinlet pressure is that due to fluctuations in steam pressure or temperature regulating throttle valve, steam trap at the entrance of the minimum workingGate Valves pressure; steam trap steam trap outlet pressure is the highest form of work after the back pressure may be When discharged to the atmosphere, the actual pressure steam trap inlet pressure by the decision. 2. According to the steam heating equipment in normal working hours and the condensation of water, multiplied Butterfly Valvesby the selected correction factor k, then follow the displacement of steam trap selection. 3. Condensate water can beCheck Valves calculated using the following methods: (1) pipeline running to the condensation of water Q = q0L (1-Z /%) (kg / h), this formula: Q: Condensation of water (kg / h) q0: fluorescent tubes, the condensation of water (kg / h) L: distance between the hydrophobic (m) Z: thermal efficiency (%) (2) steam heating equipment Globe Valvesin operation and the condensation of water Q = VrC △ T / Ht, in this formula: Q: Condensation of water (kg / h) V: volume of the heated object (m3) r: density of the object to be heated (kg / m3) C: Liquid Heat (kcal / kg.OC) △ T: liquid temperature (OC) H: steam latent heat (kcal / kg) t: heating time Four. All types of steam traps and the principle of different fluid properties vary, the selection can be based on the use of different occasions, choose a different steam traps
