供应高阀蜗轮V型球阀
蜗轮V型球阀介绍球阀往往是靠阀后或阀前阀座达到单面密封的,只有极个别特殊场合才使用阀前,阀后双面密封.因此,在通常情况下,只有一半球面(甚至更少)起密封作用,于是产生了V形球球阀.V形球特点:1、球体重量轻,这对于节约材料尤其是***材料有不可低估的经济效益.2、精加工表面体积小,减少加工时间3、能有效地减小球阀启动时的惯性力.主要用于输送纤维和纸浆等介质.球体上的V形缺口能起切断作用,以避免纤维物料粘在球体.阀体和阀座之间,另外V形球还广泛用来调节流量.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、蜗轮V型球阀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H3274379389479552736736926105913931583L2270405405576576776776776106013601360蜗轮V型球阀PN2.5MPa公称通经506580100125150200250300400500L124145165194210229243297338520600H102114127152184219273360395470580手动H1107125152178300330398495580670840E------116116171257257F------350350400400400W2304040065010501050600600800800800Wt(Kg152430558711825537053310302100电动H2-----235235400400410420L1-----235235235259400410气动H33403794524796466668141002105912051295L240540557457675675610601060106013602840本公司供应高阀蜗轮V型球阀质量保证,欢迎咨询洽谈。)
