GQ47Y轨道球阀产品详细介绍产品介绍：产品名称:GQ47H轨道球阀型号：轨道口径：15～600mm压力：1.6～2.5MPa材质：铸钢、不锈钢一、GQ47H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、GQ47H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、GQ47型PN1.6MPa～2.5MPa主要连接尺寸及重量公称通经DN1520253240506580100125150200250300350400450500600L1301501601802002302903103504004806007308509801100120012501450H1220230240260307360410483512543581617672723758791828870940H24504865255506106406406757107408209059559901050110012701450H34154555005355806056406757107408209059559901050110012701450H4370400440460480500550600650713760820875930962102012851625GQ47型PN4.0MPa公称通经DN1520253240506580100125150200250300350400450500600L130150160180200230290310350)
