GQ647Y气动轨道球阀产品详细介绍【详细说明】球阀系列:GQ647Y气动轨道球阀的详细资料：GQ647Y气动轨道球阀是新型实用产品，具有旋转球芯90度摆切断的一种高科技型球阀。国内目前所用Q型球阀均是在给定预紧力下球芯与阀座摩擦进行开与关，经常导致密封面损坏，阀门泄漏和卡死现象，轨道球阀就是针对上述常见缺陷进行更新设计使球芯旋转90度再开关的新型球阀，该球阀能使密封面无摩擦结合，达到无泄漏的安全目的，并大大提高了阀门的使用寿命。一、GQ647H气动轨道球阀结构特点传统的球阀，无论是浮动式或固定式，球体与阀座始终接触，开关扭矩大，密封面容易损伤，轨道球轮着启闭时，球体先偏转-δ角，然后转动，开关全过程中球体与阀座脱离，故阀座不会被擦伤，并且启闭扭矩小。二、GQ647H气动轨道球阀主要零件材料零件名称材料阀体WCBZG1Cr5Mo18-8CrNi18-12CrNiMo阀盖WCBZG1Cr5Mo18-8CrNi18-12CrNiMo阀杆2Cr1338CrMoA11Cr18Ni9Ti1Cr18NiMo2aTi球体WCB+HCr1Cr5Mo18-8CrNi18-12CrNiMo阀座PTFE/13Cr/CrNiSS+STELLITE螺柱B7/35CrMoA1Cr17Ni2螺母2H/452Cr13填料PTFE/增强柔性石墨三、GQ647型PN1.6MPa～2.5MPa主要连接尺寸及重量公称通经DN1520253240506580100125150200250300350400450500600L1301501601802002302903103504004806007308509801100120012501450H1220230240260307360410483512543581617672723758791828870940H24504865255506106406406757107408209059559901050110012701450H34154555005355806056406757107408209059559901050110012701450H4370400440460480500550600650713760820875930962102012851625GQ647型PN4.0MPa公称通经DN1520253240506580100125150200250300350400450500600L1301501601802002302903103504004806007308509801100120012501450H1230240260280320360436492527607649701750750790832875910980H24865255506106406406757107408209059559901050110012701450H34555005355806056406757107408209059559901050110012701450H4400440460480500550600650713777835890950980104013051650GQ647型PN4.0PMPa公称通经DN1520253240506580100125150200250300350400500600L130150160180200230290310350400480600730850980110012501450H12402602803003293654505095416637257817908068218588981020H25255506106406406757107408209059559901050110012701450H35005355806056056206406857358509009201100125013401555H4440460480500550600650713777835890950980104013051650)
