(吊桶)进口倒置桶蒸汽疏水阀 主要性能 Main performance

倒置桶蒸汽疏水阀采用球面密封，拉杆耐磨损性好，阀芯更深地陷入阀座，从而保持了密封性，阀芯支架与特殊设计而成的"超级杠杆"相配合。阀芯在支架内是自由浮动的，避免了关闭时产生的刚性碰撞 RETZ inverted bucket steam drain valve adopts spherical seal, with good wear resistance of the pull rod. The valve core is deeper into the valve seat, so as to maintain the tightness. The valve core support is matched with the specially designed "super lever". The valve core is free floating in the bracket to avoid rigid collision during closing

特点∶ Performance characteristics

可承受高背压，可达90%  Can withstand high back pressure, up to 90%

抗水击∶开口吊桶结构不会因水击而遭损坏  Water hammer resistance: the open bucket structure will not be damaged by water hammer

阀体内设有滤网，且阀瓣与阀座位于阀体的顶部，污物不会存积在阀孔处  The valve body is provided with a filter screen, and the valve disc and the valve seat are located at the top of the valve body. Dirt will not be accumulated at the valve hole

球面密封无集中磨损，关闭阀座孔时，由于采用了浮动杠杆机构，具有软着陆特点，提高了使用寿命  The spherical seal has no concentrated wear. When the valve seat hole is closed, the floating lever mechanism is adopted, which has the characteristics of soft landing and improves the service life

独特的杠杆机构将倒置桶重力放大，以便开启受到系统压差作用的阀瓣。杠杆机构为自由浮动式，没有固定支点造成的磨损  The unique lever mechanism enlarges the gravity of the inverted bucket to open the valve disc affected by the system pressure difference. The lever mechanism is free floating, without wear caused by fixed fulcrum

排放口完全被水封包围，可防止新鲜蒸汽损失 The discharge port is completely surrounded by water seal to prevent the loss of fresh steam

倒置桶疏水阀排放动作是间断的，但其凝结水排放是连续的，不存在凝结水的积聚问题 RETZ The discharge action of the inverted bucket drain valve is intermittent, but the condensate discharge is continuous, and there is no accumulation of condensate
