QB型系列刀閘閥吸取了國內(nèi)外*技術(shù)和結(jié)構(gòu)優(yōu)點(diǎn)，排除了其他廠家所產(chǎn)刀閘閥在使用中存在的問題，此閥門主要由閥體、閘板、閥桿、閥桿螺母、密封圈、操作件組成。閘板底部做成刀形斜面具有切斷介質(zhì)功能，而且閘板關(guān)閉時通過閥體上的鍥塊緊靠閘板斜切面使得閘板緊緊貼靠閥座密封面，從而起到了密封效果。而且此產(chǎn)品的軟密封結(jié)構(gòu)的密封圈是由金屬圈壓套在閥座上的階梯凹槽內(nèi)，具有密封不脫落，而且可以很方便的更換等優(yōu)點(diǎn)。并且整體輕小、結(jié)構(gòu)精巧、密封性能可靠、使用壽命長、具有切斷介質(zhì)等優(yōu)點(diǎn)，廣泛適用于造紙、水利、礦業(yè)、化工、食品等領(lǐng)域。汽缸配三連件，電磁閥，等配件可實(shí)現(xiàn)遠(yuǎn)程控制。

QB Series Knife Gate Valve absorb the advantages of technology and structure both at home and aboard to exclude other knife gate valves' shortcomings   when using . This knife gate valve is made up withe body、disc、stem、stem nut、sealing ring and operation parts. The bottom of the disc is made of knife-shaped gate with a cut off function of the medium. When gate is closed , oblique plane of gate valve encounters wedge block of gate to achieve sealing effect. And the structure of the soft sealing ring of this product is pressed by a metal ring set in the seat within a groove on the ladder which can't drop and be convenient to change. And it's small in size, structure compact, sealing reliable and long service life. It can cut off the media, etc. It's widely used in papermaking, water conservancy, mining, chemical, food and other fields. Cylinder goes together with three connected parts, solenoid valves, and other accessories can realize remote control.
