结构特点：1、本阀结构结实、重量轻、体积小使用压力范围大，不需任何调节。
2、具有空气排放装置，迅速排除初时空气、保证快速启动。
3、可承受过热蒸汽、抗冰冻能力强，安装位置不受限制，均能正常工作。
Introduction:According to the thermodynatic principle,the disc trap drives the change of the power,causing differences between the upper and lower valve discs.The valve disc will be opened and closed accordingly to resist gas and discharge water.This kind of trap enjoys an extensive application in main pipelines,heat accompanying pipelines and small steam equipments.
Structure:1.This trap is featured with solid structure,light weight,small volume and different pressure without any adjustment.
2.Hving gas discharging equipment for rapidly discharging gas to ensure fast start.
3.Excellent abilities to endure steam and to resist frozen.It can be installed in free way.
