(吊桶)進口倒置桶蒸汽疏水閥 主要性能 Main performance

倒置桶蒸汽疏水閥采用球面密封，拉桿耐磨損性好，閥芯更深地陷入閥座，從而保持了密封性，閥芯支架與特殊設計而成的"超級杠桿"相配合。閥芯在支架內是自由浮動的，避免了關閉時產生的剛性碰撞 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

特點∶ Performance characteristics

可承受高背壓，可達90%  Can withstand high back pressure, up to 90%

抗水擊∶開口吊桶結構不會因水擊而遭損壞  Water hammer resistance: the open bucket structure will not be damaged by water hammer

閥體內設有濾網，且閥瓣與閥座位于閥體的頂部，污物不會存積在閥孔處  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

球面密封無集中磨損，關閉閥座孔時，由于采用了浮動杠桿機構，具有軟著陸特點，提高了使用壽命  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

獨特的杠桿機構將倒置桶重力放大，以便開啟受到系統壓差作用的閥瓣。杠桿機構為自由浮動式，沒有固定支點造成的磨損  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圍，可防止新鮮蒸汽損失 The discharge port is completely surrounded by water seal to prevent the loss of fresh steam

倒置桶疏水閥排放動作是間斷的，但其凝結水排放是連續的，不存在凝結水的積聚問題 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
