根据疏水阀工作原理的不同,可化为以下三种类型:
机械型:依靠蒸汽疏水阀内凝结水液位高度的变化而动作,包括:
浮球式:浮子为封闭的空心球体。
敞口向上浮子式:浮子为开口向上的桶型。
敞口向下浮子式:浮子为开口向下的桶型。
热静力型:依靠液体温度的变化而动作,包括:
双金属片:敏感元件为双金属片。
蒸汽压力式:敏感元件为波纹管或墨盒,内部充入挥发性液体。
热动力型:依靠液体的热动力学性质的变化而动作。
圆盘式:由于在相同的压力下,液体与气体的流速不同,所产生的不同的动,静压力,驱使圆盘阀片动作。
脉冲式:由于不同温度的凝结水通过两极串连节流孔板时,会在两极节流孔板之间形成不同压力,驱使阀瓣动作。
According to the working principle of steam trap is different, can be turned into the following three types:
Mechanical type: rely on steam trap with the changing of water level in the action, including:
Ball float, float for a closed hollow sphere.
Exposure to float upward: float for opening up the bucket.
Exposure to downward float type: float down with the bucket.
Hot static type: depend on the liquid temperature change and action, including:
Bimetallic strip: sensitive element for bimetallic strip.
Steam pressure type: sensitive element for corrugated tube or cartridge, internal filling the volatile liquid.
Thermodynamic model: depend on the change of the thermal dynamic properties of the liquid and action.
Disc type: because be in the same pressure, liquid and gas flow rate, produced by the different dynamic, static pressure and driving disc valve action.
Impulse type: due to the different temperature of the condensate through the poles string throttling orifice plate, will in different pressure between the polar orifice plate, drive disc movement.
