北京信美迪阀门有限公司《进口电动偏心球阀》口径：50～500mm压力：1.6MPa～2.5MPa材质：铸钢、不锈钢一、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，所以阀座不会被擦伤，并且启闭扭矩小。二、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、主要连接尺寸及重量PN1.6MPa公称通径506580100125150200250300400500L124145165194210229243297338520600H102114127152184219273360395470580手动H1107125152178300330398495580670840E------116116171257257F------350350400400400W2304040065010501050600600800800800Wt(Kg1216223558742053224608641600电动H2-----554600652760830940L1-----235235235259400410气动H3274379389479552736736926105913931583L2270405405576576776776776106013601360PN2.5MPa公称通径506580100125150200250300400500L124145165194210229243297338520600H102114127152184219273360395470580手动H1107125152178300330398495580670840E------116116171257257F------350350400400400W2304040065010501050600600800800800Wt(Kg)152430558711825537053310302100电动H2-----235235400400410420L1-----235235235259400410气动H33403794524796466668141002105912051295L240540557457675675610601060106013602840)
