一、概述疏水阀用于蒸汽供热设备和蒸汽输送管线上,起自动阻汽排水的作用,是蒸汽系统的重要配件。其性能的优劣,对于系统的正常运行、设备热效率的提高及节约能源等都具有重要作用。疏水阀共有三种类型,每种类型依据不同的物理原理而动作,其分类情况是:对液面高度敏感的有浮球式、浮桶式、钟形浮子式;对温度敏感的有双金属片式,波纹管式、膜盒式;对流体性质敏感的有节流式,脉冲式,热动力式。浮球式疏水阀是一种密闭浮子式疏水阀,具有连续排水的特点,凝结水形成以后能够及时地立即排出。凝结水量大时,疏水阀的排水 First, an overview Traps for steam heating equipment and steam transmission lines, automatic steam drainage from the role of the steam system is an important part. The pros and cons of its performance, for the normal operation of the system, equipment, thermal efficiency and energy conservation have an important role. Traps There are three types of traps, each type according to different physical principles and actions, the classification is: a highly sensitive to the liquid level float, float bucket, bell-shaped float; temperature sensitive bimetal Flake, bellows, membrane cassette; sensitive to the nature of fluid throttling, pulsating, thermodynamic. Float trap is a closed float trap with continuous drainage features, after the formation of condensate can be promptly discharged immediately. When the amount of condensate water, trap drainage
