傘齒輪刀閘閥
bevel gear knife gate valve
Qb型系列刀閘閥吸取了國內外*技術和結構優點，排除了其他廠家所產刀閘閥在使用中存在的不足，是一種具有輕型、結構簡單小巧、密封性能可靠、使用壽命長、具有切斷介質等優點，其密封原理是通過閘板在關閉到底時，閘板斜切面碰到閥體上的鍥塊使得閘板緊靠密封面起到密封效果，并且閘板底部的斜切面具有切斷介質的功能，使得閥門不易受介質的堵塞卡阻。其結構可以做成硬密封、軟密封，可以根據客戶對密封要求選型。與傘齒輪輔助配合，達到很輕便的啟閉效果，此閥主要用于現代工業領域上。
QB Series Knife Gate Valve absorb the advantages of domestic and foreign advanced technology and structure to exclude other manufacturers knife gate valve produced by the shortcomings in use. it's small in size, structure compact, sealing reliable and long service life. It can cut off the media, etc. The sealing principle is that when the gate is closed to the end ,oblique plane of gate valve encounters wedge block of gate to close to achieve sealing effect, which makes the valve less blockage media . Its structure can be made into hard seal, soft seal. Sealing requirements base on customer's selection. This kind of valve is mainly used in model industry area.
