本文就浮蝶式疏水器的构造、工作原理、使用效果作一简要分析,以便合理选用疏水器,节约热能,提高设备热能利用率。一、浮蝶式疏水器的构造当前,疏水器种类繁多,按其动作原理分为机械式、热动力式、热静力式三种,应用较广泛的有机械式疏水器,例如吊桶型、浮球型、自由浮球型等疏水器;热动力式疏水器,例如园盘型疏水器;其次是热静力式疏水器,例如双金属型疏水器。但吊桶型、浮球型疏水器体积大、重量重;热动力式疏水器排放冷凝水是冲击式的,使用寿命短;双金属型疏水器金属片材料易失效,使用一段时间后,就不灵敏了:自由浮球型疏水器较以上几种疏水器不论在体积、重量、寿命、性能等方面都优越的多,浮 In this paper, the structure, working principle and using effect of floating butterfly steam trap are briefly analyzed in order to select the steam traps reasonably, save the heat energy and improve the heat utilization rate of the equipment. First, the structure of floating butterfly trap Currently, a wide range of traps, according to their action principle is divided into mechanical, thermal, thermal static three, the more widely used mechanical traps, such as bucket type, A float type, a free float type, or the like; a thermodynamic steam trap, such as a disk type trap; and a thermostable trap, such as a bimetallic trap. But the bucket type, float type steam traps bulky, heavy weight; thermodynamic steam trap drainage condensate is impact type, short service life; bimetallic traps metal sheet material failure, use for some time, not Sensitive: free float steam trap than the above types of steam traps in terms of volume, weight, life expectancy, performance, etc. are superior and more floating
