撑拢式金属双向双密封球阀产品型号：CLQ47Y1.6～16.0(CL150～1500)产品结构特点：撑拢式金属双向双密封球阀是公司通过多年的实践，成功研制出的一种专利产品，其利用球体上导向柱与撑拢盘导向槽的上下间距的不对等，通过对撑拢盘沿轨迹升降使两球瓣绕铰支销回转，从而使密封脱离回转/回转压紧以达到启闭的效果。如图所示：升降杆上升带动撑拢盘沿导向柱向上移动，从而使球体收拢，脱离密封面，当升降杆继续上升，撑拢盘带动球体旋转90度，使阀门开启。相反的过程阀门关闭。主要零件的材料说明：名称\主体材料A216WCBA217WC6A217WC9A351CF8A351CF3A351CF8MA351CF3M阀体、阀盖A216WCBA217WC6A217WC9A351CF8A351CF3A351CF8MA351CF3M支架A216WCBA217WC6A217WC9A351CF8A351CF3A351CF8MA351CF3M阀座A105+STLA304+STLA304+STLA304+STLA304+STLA316+STLA316L+STL球体A105+STLA217WC6+STLA217WC9+STLA351CF8+STLA351CF3+STLA351CF8M+STLA351CF3M+STL阀杆A182F6+渗氮17-4PH+渗氮A182F304+渗氮A82F304L+渗氮A182F316+渗氮A182F316L+渗氮撑拢盘A105+ER410F11+STLF22+STLA304+STLA304L+STLA315+STLA316L+STL螺栓A193B7A193B16A193B16A193B8A193B8A193B8MA193B8M螺母A1942HA194-7A194-7A194-8A194-8A194-B8MA194-8M填料碳素纤维+304钢丝/柔性石墨RTFERTFERTFERTFE阀杆螺母A493D2导向销40Cr+淬火衬筒45+镀Ni-PF321+镀Ni-PF321+镀Ni-PF321+镀Ni-PF304L+镀Ni-PF316+镀Ni-PF316L+镀Ni-P中道垫片304片加柔性石墨缠绕316片加紧RTFE中心轴G40Cr+高频淬火A182F316+渗氮手轮A395（QT400-17）适用介质≤425℃≤545℃≤570℃≤200℃≤200℃≤200℃≤200℃适用温度水、蒸汽、油品（含微小颗粒）氧化性介质硝酸类醋酸类尿素、氨等主要外形尺寸：公称压力形式公称通径外形尺寸公称压力形式公称通径外形尺寸公称压力形式公称通径外形尺寸HLEHLEHLE1.61253801801802.51253801801804.0125380180180323801801803238018018032380180180404202001804042020018040420200180504902302005049023020050490230200655502903006555029030065550290300806003103008060031030080600310300100660350300100660350300100660350300150705480400150705480400150705480400200740600450200740600450200740600450225091073031022509107303102250910730310300980850310300980850310300980850310350108098046035010809804603501080980460400122011004604001220110046040012201100460450134012004604501340120046045013401200460500148012504605001480125046050014801250460600182014506006001820145060060018201450600700198016506007001980165060070019801650600公称压力形式公称通径外形尺寸公称压力形式公称通径外形尺寸公称压力形式公称通径外形尺寸HLEHLEHLE6.412538018018010.012540023020016.012525230200323801801803240026020032322602004044020018040460260300404026030050510230200505303003005050300300655702903006559034035065653403508062031030080645380400808038040010068035030010070543040010010043040015072548040015075055045015015055045022007656003102200780650310220020065031025093573031025096577531025025077531030010108504603001040900460300300900460350111098046035011401025460350350102546040012501100460400128011504604004001150460450137012004604501405127546045050015201250600500155514006005006001860145060060018951650600600公称压力形式公称通径外形尺寸公称压力
