蜗轮V型球阀产品名称：蜗轮V型球阀产品特点：1、V型切口的球芯与金属阀座之前具有剪切作用，特别适用于含纤维、微小固体颗粒、料浆等介质；2、蜗轮传动V形切断球阀还具有调节并可靠定位能力，流量特性为近似百分比，可调范围广；3、采用板簧加载的可动阀座结构，阀座与球芯不会产生卡阻或脱离等问题，密封可靠，使用寿命长。蜗轮V型球阀的详细资料：一、蜗轮V型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、蜗轮V型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、PN1.6MPa主要连接尺寸及重量公称通经506580100125150200250300400500L124145165194210229243297338520600H102114127152184219273360395470580手动H1107125152178300330398495580670840E------116116171257257F------350350400400400W2304040065010501050600600800800800Wt(Kg1216223558742053224608641600电动H2-----554600652760830940L1-----235235235259400410气动H3274379389479552736736926105913931583L2270405405576576776776776106013601360PN2.5MPa公称通经506580100125150200250300400500L124145165194210229243297338520600H102114127152184219273360395470580手动H1107125152178300330398495580670840E------116116171257257F------350350400400400W2304040065010501050600600800800800Wt(Kg152430558711825537053310302100电动H2-----235235400400410420L1-----235235235259400410气动H33403794524796466668141002105912051295L240540557457675675610601060106013602840)
