供应高阀轨道球阀
轨道球阀结构特点传统的球阀,无论是浮动式还是固定式,球体与阀座始终接触,开关扭矩大,密封面容易损伤,轨道球阀在启闭时,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。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2Cr1338CrMoA11Cr18Ni9Ti1Cr18Ni12Mo2aTi球体WCB+HCr1Cr5Mo18-8CrNi18-12CrNiMo阀座PTFE/13Cr/CrNiSS+STELLITE螺柱B7/35CrMoA1Cr17Ni2螺母2H/452Cr13填料PTFE/增强柔性石墨轨道球阀应用规范1、设计、制造按GB/122372、结构长度按QB/ZMV1073、连接法兰JB/T79.1~79.4GB/T9113.1~9113.44、阀门检查和试验按GB/13927GDQ47型PN1.6~2.5MPa主要外形尺寸公称通径DN1520253240506580100125150200250300350400450500600L1301501601802002302903103504004806007308509801100120012501450H1220230240260307360410483512543581617672723758791828870940H24504865255506106406406757107408209059559901050110012701450H34154555005355806056056206406857358509009201100125013401555H4370400440460480500550600650713760820875930962102012851625GDQ47型PN4.0MPa主要外形尺寸公称通径DN1520253240506580100125180200250300350400450500600L1301501601802002302903103504004806007308509801100120012501450H1230240260280320360436492527607649701750750790832875910980H2486525550610640640675710740820905955990105110012701450H34555005355806056056206406857358509009201100125013401555H4400440460480500550600650713777835890950980104013051650本公司供应高阀轨道球阀质量保证,欢迎咨询洽谈。)
