全封闭刀闸阀 带盖刀型闸阀

进口全封闭刀闸阀，带盖刀型闸阀性能描述 Performance description

全封闭刀闸阀(刀型闸阀，刀阀)双重密封式结构，是一种填料再盖上盖式双重密封中压刀闸阀，阀的填料处设有第一道密封起到刮闸板表面的污物和防止杂物上流，而影响闸板在上盖内的启闭受到障碍，在填料的外面再增设一个全密封的上盖来有效的保证穿过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
