自由浮球式疏水阀的结构简单，内部只有一个活动部件精细研磨的不锈钢空心浮球，既是浮子又是启闭件，无易损零件，使用寿命很长，“银球”牌疏水阀内部带有Y系列自动排空气装置，非常灵敏，能自动排空气，工作质量高。 设备刚启动工作时，管道内的空气经过Y系列自动排空气装置排出，低温凝结水进入疏水阀内，凝结水的液位上升，浮球上升，阀门开启，凝结水迅速排出，蒸汽很快进入设备，设备迅速升温，Y系列自动排空气装置的感温液体膨胀，自动排空气装置关闭。疏水阀开始正常工作，浮球随凝结水液位升降，阻汽排水。自由浮球式疏水阀的阀座总处于液位以下，形成水封，无蒸汽泄漏，节能效果好。最小工作压力0.01Mpa，从0.01Mpa至{zg}使用压力范围之内不受温度和工作压力波动的影响，连续排水。能排饱和温度凝结水，最小过冷度为0℃，加热设备里不存水，能使加热设备达到{zj0}换热效率。背压率大于85%，是生产工艺加热设备最理想的疏水阀之一。

Free float-type trap is simple, and has only one moving part finely ground stainless steel hollow float, float is both open and close parts, no wearing parts, long service life, "Silver Ball" brand within the zone trap a row of Y series automatic air devices, very sensitive, automatically scheduling the air, high quality work. Equipment has just started work, the pipeline of the air through the Y series automatic discharging exhaust air devices, low temperature condensate into the trap, the condensate water level rise, float up, the valve opens, the rapid discharge condensate, steam soon into the equipment, equipment rapid warming, Y series automatic scheduling of air temperature of liquid expansion devices, automatic scheduling of air device closed. Traps started work, with the condensate level float down, waste gas drainage. Free ball float type steam trap valve seat total in the level below, forming a water seal, no steam leakage, energy saving effect is good. Minimum working pressure 0.01Mpa, to a maximum working pressure from 0.01Mpa within the temperature and pressure fluctuations from the impact of continuous drainage. Condensate saturation temperature can be row, the minimum undercooling to 0 ℃, heating equipment is not in storage, can achieve the best heat transfer efficiency heating equipment. Back pressure more than 85%, the production process heating equipment, one of the best traps.
