 Introduction to Knife Gate 

 The opening and closing parts of the knife gate is a gate, perpendicular to the direction of movement of the fluid direction of the gate, manual knife gate valve can only be fully open and fully closed, can not be adjusted and throttle. 

 Knife Gate Valve The main purpose 

 For mine plant preparation, slagging, urban sewage treatment, food, paper, pharmaceutical, oil, chemical oil, water, steam pipes on the road, water, mud, connect or disconnect the line of gold powder , ores, slag, slime, pulp, wood pulp, tailings, fibers, dust, chemicals, sewage treatment, sedimentation tanks, asphalt, silos, export, fruits, grains, slaughter plant wastewater and other media. 

 Knife gate valve to cut off media function 

 The name suggests is the bottom of the flat valve plate of the knife gate valve has a knife oblique incision, cut off the media function, making the valve is closed from the medium blocked. This valve is generally used to hoist the circulation of the pulp, coal ash, chemical raw materials, sewage, food and other media. The pressure range is generally 1.6MPa or less, the temperature is below 120 ℃, high temperature can also be used instead of using special materials. Sealing performance requirements can be divided into flexible seal and hard seal. The soft seal can reach leaks, hard seal according to the different leak rank test. The valves are easy to operate, open free, flexible and reliable movement; the valve assembly and maintenance is simple and reasonable structure, sealing, seals replacement is convenient and practical.
