進口全封閉刀閘閥，帶蓋刀型閘閥性能描述 Performance description

全封閉刀閘閥(刀型閘閥，刀閥)雙重密封式結構，是一種填料再蓋上蓋式雙重密封中壓刀閘閥，閥的填料處設有第一道密封起到刮閘板表面的污物和防止雜物上流，而影響閘板在上蓋內的啟閉受到障礙，在填料的外面再增設一個全密封的上蓋來有效的保證穿過填料腔流到外面的泄漏 RETZ The fully enclosed knife gate valve (knife gate valve, knife valve) is a double sealed structure, which is a double sealed medium pressure knife gate valve with packing and cover. The packing part of the valve is equipped with a first seal to scrape the dirt on the surface of the gate plate and prevent debris from flowing up, which affects the opening and closing of the gate plate in the upper cover. A fully sealed upper cover is added outside the packing to effectively ensure leakage through the packing chamber to the outside
