工业锅炉用快速排污阀采用浮动闸板型结构,为自压密封,具有开关迅速及流阻小,排量大。将手柄逆时针转动,齿轮轴驱使阀杆带动闸板迅速上升,打开通道,使沉积在锅炉的饱和联箱底部的松软的水垢和沉渣,借锅内蒸气压力骤然排出炉外,手柄来转动多次,就可达到排污的目的。 Structure eatures and prineiple: Adopen with e the structure of flOAt slide plate,these valves are selfsealed.They have the chareteristics of quick open /close,small flowing clockuise,the gear shaft clrives the valve to make slide plate rise quickly,thus open the clannel,the AIr bag deposited in the boiler and the soft boiler scale and sedimentation in the bottom of cabinet and stream pressure in the boiler can be diseharged.Rotate the handle repeatly,the waste can be discharged thoroughly. | ||
