疏水阀知识
疏水阀在蒸汽加热系统中起到阻汽排水作用，选择合适的疏水阀，可使蒸汽加热设备达到*高工作效率。要想达到*理想的效果，就要对各种类型疏水阀的工作性能、特点进行**的了解。疏水阀的品种很多，各有不同的性能。选用疏水阀时，首先应选其特性能满足蒸汽加热设备的*佳运行，然后才考虑其他客观条件，这样选择你所需要的疏水阀才是正确和有效的。
疏水阀要能“识别”蒸汽和凝结水，才能起到阻汽排水作用。“识别” 蒸汽和凝结水基于三个原理：密度差、温度差和相变。于是就根据三个原理制造出三种类型的疏水阀：分类为机械型、热静力型、热动力型。1.在生产工艺的换热设备，烘干室，快速热交换器，蒸馏设备等需要快速升温，不允许存有凝结水的生产加热设备，应该选用机械型疏水阀。2.在蒸汽管道，伴热管线、小型加热设备，采暖设备，温度要求不高的用汽设备，应该选用热静力型疏水阀。3.在高温高压过热蒸汽管线和设备上，应该选用过热蒸汽专用疏水阀。

steam traps steamheating system in a waste gas drainage role in the selection ofsuitable steam traps allow steam heating equipment for the highestefficiency. To achieve optimal results, it is necessary for alltypes steam traps work performance and characteristics of acomprehensive understanding. steam traps many varieties, each withdifferent performance. steam traps choice, should first elect theiridentity can best meet the steam heating equipment operation beforeconsidering other objective conditions, such choices you need steamtraps is correct and effective.
steam traps to be "identified" steam and condensed water can play arole in blocking air drainage. "identification" and the condensedsteam water based on three principles : the poor density, andtemperature difference of change. So on the basis of threeprinciples of creating three types of steam traps : classified asmechanical type, thermal static type, thermal power-based. 1. Inthe heat production equipment, drying room, rapid heat exchangers,distillation equipment needs rapid warming, not a condensed waterheating equipment production should be chosen mechanical type steamtraps. 2. In steam pipes, coupled heat pipelines, small heatingequipment, heating equipment, air temperatures do not ask for theuse of equipment, it should be the choice of hot static type steamtraps. 3. Overheating in high-temperature high-pressure steampipelines and equipment, should choose an exclusive steam trapssteam
