電液動刀閘閥
electro-hydraulic knife gate valve
電液動刀閘閥是由電液動裝置同刀閘閥配合，實(shí)現(xiàn)電控液動，同時(shí)配合信號輸出控制，可實(shí)現(xiàn)遠(yuǎn)程自控，是一種理想的智能式自控調(diào)節(jié)刀閘閥。刀閘閥吸取了國內(nèi)外*技術(shù)和結(jié)構(gòu)優(yōu)點(diǎn)，是一種具有輕型、結(jié)構(gòu)簡單小巧、密封性能可靠、使用壽命長、具有切斷介質(zhì)等優(yōu)點(diǎn)，其密封原理是通過閘板在關(guān)閉到底時(shí)，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(zhì)的功能，使得閥門不易受介質(zhì)的堵塞卡阻。其結(jié)構(gòu)可以做成硬密封、軟密封，可以根據(jù)客戶對密封要求選型。
Electric hydraulic knife gate valve is that electric hydraulic actuating devices work together with knife gate valve to achieve electronically controlled hydraulic,meanwhile,it cooperates with the signal output control . It's an ideal of a smart-controlled adjustable knife gate valves. Knife Gate Valve absorbs the advantages of technology and structure both at home and aboard to exclude other knife gate valves' shortcomings when using .It's a kind of lightweight, compact, simple structure, reliable sealing and long service life, and can cut off 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 a hard seal, soft seal. Sealing requirements base on customer's selection.
