进口手动刀闸阀

德国巴赫进口手动刀闸阀概述：Introduction of manual knife gate valve imported from Germany Bach:

 进口刀型闸阀顾名思义就是平板阀板底部具有刀型斜切口，具有切断介质的功能，使得阀门关闭不受介质阻塞。此阀门一般用于纸浆、煤灰、化工原料、污水、食品等介质的流通启闭。压力范围一般都1.6MPa以内使用，温度一般在120℃以下使用，高温也可以用特殊材质代替使用。

Imported knife gate valve, as its name implies is flat plate valve plate at the bottom with a knife type oblique incision, with the function of cutting off the medium, so that the valve closed without media obstruction. This valve is generally used for pulp, coal ash, chemical raw materials, sewage, food and other media circulation open and close. The pressure range is generally less than 1.6MPa, the temperature is generally below 120 degrees of use, high temperature can also be replaced by special materials.
 该阀具有开关轻巧、密封可靠、弹性记忆佳及使用寿命长等显著优点。可广泛用于自来水、污水、建筑、石油、化工、食品、医药、轻纺、电力、船舶、冶金、能源系统等体管线上作为调节和截流装置使用。有板式闸阀、刀型泥浆闸阀，刀型排渣闸阀，单夹式渣浆闸阀和手动单夹式刀型闸阀。

进口手动刀闸阀的定义：Definition of imported manual knife gate valve:

 进口刀闸阀又称刀型闸阀、刀门闸阀、浆液阀、泥浆阀，它的启闭件是闸板，闸板的运动方向与流体方向相垂直，靠可以切割纤维材料的刀刃形闸板来切断介质，闸板有两个密封面,较常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异,通常为50,楔式刀型闸阀的闸板可以做成一个整体，叫做刚性闸板；Imported knife gate valve called knife type valve, knife gate valve, slurry valve, slurry valve, it is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, by the blade shaped gate can cut fiber material to cut off the media, there are two gate sealing surface, the most commonly used mode of gate valve the two sealing surface to form a wedge, the wedge angle varies with the valve parameters, usually 50, wedge type knife gate valve can be made into a whole, called the rigid gate也可以做成能产生微量变形的闸板,以改善其工艺性,弥补密封面角度在加工过程中产生的偏差,这种闸板叫做弹性闸板。阀体实际上不存在腔室，闸板在侧面导向槽内升降，并由底部的凸耳紧压在阀座上，如需达到较高的介质密封性时，可选用O形密封阀座实现双向密封。刀闸阀具有较小的安装空间，工作压力低，不易堆积杂物，价格较低。
 进口刀型闸阀驱动方式：手动，链轮，电动，气动，液动，伞齿轮，电控液动和气液动等驱动方式。刀型闸阀外形：明杆，暗杆两种。刀型闸阀材质：铸铁、铸钢、碳钢、不锈钢、衬氟等。刀型闸阀密封：硬密封，软密封，单面密封，双面密封等多种材质密封。
超薄型的刀闸阀以其体积小、流阻小、重量轻、易安装、易拆卸等优点完全解决了普通闸阀、平板闸阀、球阀、截止阀、调节阀、蝶阀等类阀门的流阻大、重量大、安装难、占地面积大等的疑难问题。刀闸阀出现后，大量的通用切断类阀门和调节阀门已被之取代。到今天，大部分国家刀闸阀用量非常大的是美国和日本。
