防爆電動V型球閥

anti-explosion of electric V-type control ball valve

V型閥采用金屬硬密封結(jié)構(gòu)，V型閥芯及金屬閥座在回轉(zhuǎn)過程中，球芯的V型缺口與閥座做比例流量調(diào)節(jié)，并且密封面緊密配合，V型口具有強(qiáng)大切斷介質(zhì)、雜質(zhì)的功能，避免閥門卡死現(xiàn)象發(fā)生，并具有自潔功能，因此適用于造紙、化工、冶金等工業(yè)企業(yè)中含有纖維或微小固體顆粒的懸濁液。配合電動執(zhí)行器可以實現(xiàn)遠(yuǎn)程閥門流量開度控制，在無電源情況下也可以手動進(jìn)行操作。具有額定流量系數(shù)大，可調(diào)比大，密封效果好，調(diào)節(jié)性能靈敏，體積小，可豎臥安裝等優(yōu)點。適用于控制氣體，蒸氣和液體等介質(zhì)。尤其是適用于控制纖維性和有微小固體顆粒的懸濁液介質(zhì)的理想產(chǎn)品

V- type of trim with metal seal structure , V- notched and seat  do proportion of flow regulation ,and sealing surface works closely when V- spool and metal seat is in rotation process. V- I can cut media and impurities functions to avoid be chocked to death ,and they can self-cleaning function. So this kind of valve can be used in paper making ,chemical ,metallurgical and other industrial enterprises containing  fibers or tiny solid particles in suspension. With electric actuator ,it's can be controlled through valve flow and also can be operated manually when without power . It's with large flow coefficient  and adjustable, excellent  sealing , sensitivity  regulate performance ,small size, vertical horizontal installed. It's applicable to control gas, steam and liquid ,etc. It's particular suitable for controlling fibrous and suspension with small solid .
