氣動V型調(diào)節(jié)球閥
pneumatic 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。配合氣動執(zhí)行器，可以實(shí)現(xiàn)90°范圍的啟閉，跟定位器配套使用可實(shí)現(xiàn)遠(yuǎn)程微電腦控制閥門流量開度，可實(shí)現(xiàn)比例調(diào)節(jié)；與二位五通電磁及控制箱配套使用，可實(shí)現(xiàn)開關(guān)控制。適用于氣體、液體、固態(tài)顆粒介質(zhì)的控制。
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 pneumatic actuator,it can achieved 90° range of hoist, Working with locator supporting , it can remote microcomputer controlling flow opening to achieve proportion of adjustment; Working with two five-pass solenoid and the control box,it can achieve switches controlling. It can be used for gas, liquid, solid particles,
