饱和蒸汽主管的疏水阀如何选型? 来源:三盛疏水阀 时间:2018-10-02 点击量:
饱和蒸汽主管中通常包含有冷凝在管壁上的水膜、悬浮在蒸汽中的水滴和空气。为了使设备效率最高,必须排除空气和水。蒸汽疏水阀应将冷凝水排入到适当尺寸的冷凝水回收管,然后排至开式集水管内。由于冷凝水回收管通常和饱和蒸汽主管平行布置,所以会给人造成误导,而将主蒸汽疏水阀的所有出口都直接和回水管相连。当冷凝水回收管满溢的时候,就会产生严重的水锤现象,如果疏水阀为喷排式,将更加严重,应避免这种安装方法以防止水锤现象发生。
饱和蒸汽主管疏水量比较小,所以说低排量的热动力疏水阀最为合适。
热动力疏水阀特点:
1、可在任何方位安装,安装费用低。
2、具有排空气的功能,可防止空气的阻塞。
3、自带过滤器保护疏水阀免受杂物的损坏。
4、阀体不会被冷冻破坏,耐水锤,耐振动,耐腐蚀。
5、淬硬不锈钢阀座和阀片满足高压下的长寿命使用。
6、阀体结构简单结实,重量轻,体积小,使用寿命长。
7、工作压力范围大,不需要随着压力的变化而更换或调整阀口尺寸。
8、疏水阀只有唯一的活动部件-不锈钢碟片,故几乎不需要进行维修。

英文版:
The saturated steam main pipe usually contains water film condensated on the pipe wall, water droplets suspended in the steam and air. In order to make the equipment the most efficient, air and water must be excluded. The steam trap shall drain the condensate into a condensate recovery pipe of proper size and then into an open-type collector pipe. Since condensate recovery pipes are usually arranged in parallel with the saturated steam main pipe, it is misleading to connect all the outlets of the main steam trap directly to the return pipe. When the condensate recovery pipe overflows, serious water hammer phenomenon will occur. If the trap is jet exhaust, it will be more serious. This installation method should be avoided to prevent water hammer phenomenon.
The saturated steam header has a relatively small amount of hydrophobicity, so the low displacement thermal steam trap is most suitable.
Features of thermal steam trap valve:
1. It can be installed in any direction and the installation cost is low.
2. It has the function of exhausting air to prevent air blockage.
3, with filters to protect the trap from debris damage.
4, the valve body will not be frozen damage, water hammer, vibration resistance, corrosion resistance.
5. Hardened stainless steel seats and valves meet long service life under high pressure.
6. The valve body has a simple structure, light weight, small volume and long service life.
7, the scope of work pressure is large, no need to change or adjust the size of valve orifice with the change of pressure.
8. Steam traps have only one moving part - stainless steel discs, so there is little need for maintenance.
