           蒸汽疏水阀的动作正常与否，在很大程度上影响着蒸汽使用设备，包括硫化机在内的性能和效率。同时，也影响这些设备的使用寿命，水力控制阀 有时还会带来意外的恶性事故，给企业造成巨大损失。因此，选择好疏水阀十分重要，

    应从下列疏水阀的性能招标中选择：

 　　(1)排放饱和水的能力和过冷度　　蒸汽放出热量后变为饱和水。低温阀门如果疏水阀可将饱和水排出，新鲜的蒸汽及时补充进硫化机使得设备始终保持在较高的温度下，可提高生产效率和产品质量。自由浮球式，杠杆浮球式，浮桶式疏水阀都可排饱和水，过冷度为0-2℃。　　过冷度是指疏水阀能连续排放热凝结水的温度与鸭嘴阀相应压力下饱和温度之差的绝对值。排放饱和水的疏水阀可以在C点排水，不能排饱和水的疏水阀只能在E点排水，C点与E点之间的温差叫过冷度。　　圆盘式、双金属片式、波纹管式排气阀、排泥阀等疏水阀由于过冷度较大不能排放饱和水不适用于硫化机。

　　(2)疏水阀的背压率也是影响疏水阀工作的重要指标。背压率高，可以在回收凝结水时在背压较高的情况下仍可以正常工作。

　　(3)疏水阀具有止回功能，可使单台的硫化机停止过滤器工作时防止冷凝水倒流对硫化机造成不利影响，造成故障，影响使用寿命。

　　(4)选择可用于过热蒸汽的疏水阀。　　(5)能够连续排水，且排水量大、使用寿命长的疏水阀。 　　选好蒸汽疏水阀可节约大量能源和资金，当然也许一次性投资大一些，但从长远来看是合算的，既可以保证产品质量，又可以大大提高工作效率。

        Normal or not the action of steam traps, largely affects the steam use equipment, including curing press, including the performance and efficiency. Also affect the service life of these devices, sometimes bring unexpected serious accident, causing huge losses to the enterprise. Therefore, the choice is very important a good trap, trap performance Water Control valves should tender the following options: (1) discharge capacity of saturated water and undercooling After the steam releases heat into the saturated water. If the traps can be saturated water discharge, in time to addForged Steel Valves fresh steam into the curing machine makes equipment remain at relatively high temperatures, can increase production efficiency and product quality. Free float-type, lever ball float type, floating row bucket traps can be saturated water, the undercooling for the 0-2 ℃. Subcooling is setting traps to continuousOther pumps hot water discharge temperature and pressure corresponding saturation temperature difference between the absolute value. Saturated water discharge in C point drainage traps, the traps can not be ranked saturated water drainage only in the E point, C point and the temperature difference between the E point is called supercooling. Disc, two-piece metal bellows type and other traps can not be as large undercooling saturated water discharge does not apply to curing machine. (2) the rate also affect the back pressureHydraulic control valves steam trap steam trap of the important indicators. High back pressure may be in recycling water condensation in the case of high back pressure may work. (3) The trap has a return function, allows a single machine to stop working when the sulfide to prevent condensed waterCast Steel back negative impact on the curing press, resulting in failure, affect the service life. (4) the superheated steam traps can be used. (5) to continuous drainage, and the displacement of large, long service life of steam traps. Choose the right steam trap can save a lot of energy and money, and maybe a bigger one-time investment, but in the long run is cost-effective, not only can guarantee product quality, and can greatly improve efficiency.
