YHQ41F斜面球阀结构特点：1、独特的结构密封更加可靠斜面球阀又称“楔式球阀”，采用整体上装式新型结构。两阀座密封面设计成楔形两斜面，球体上部有一弹簧。在弹簧力的作用下，阀座密封面与球体紧密贴合，形成可靠的密封。2、阀杆凸肩结构即可防脱又保证了上密封性能阀杆下端设有凸肩，可在阀体内压异常升高时，防止阀杆脱出。在弹簧及介质力的作用下，阀杆凸肩压紧垫片，形成上密封效果。3、先进的防火、防静电结构在球体与阀座之间设置有防火金属环。在意外火灾阀座烧损后，金属环压在球体上起到密封作用。确保系统的安全，防止重大事故发生。球体上部的予紧弹簧可将球体与阀座摩擦产生的静电，经导线导入地下。防止因静电产生的火花点燃易燃易爆介质，保证系统的安全。4、阀门的启、闭力小，安装、维修方便阀杆填料函的密封采用填料平面与阀杆凸肩、阀盖平面的压紧，靠弹簧的予紧力及上压盖的压紧力实现密封。减轻了阀门的启、闭力。阀门采用整体上装式结构，只须将上部阀盖拆开，既可取出阀门体内全部零件。便于阀门的维修和更换。斜面球阀主要零件材料表：阀体WCBZG1Cr18Ni9TiZG1Cr18Ni12Mo2TiZG00Cr17Ni14Mo2球体1Cr18Ni9Ti1Cr18Ni12Mo2Ti00Cr17Ni14Mo2密封材质PTFE、柔性石墨、碳纤维阀杆2Cr131Cr18Ni9Ti1Cr18Ni12Mo2Ti00Cr17Ni14Mo2斜面球阀主要外形连接尺寸：PN161.6MpaDNd1LH1H2WED2D1DbfN-Φ1515130110651304565951424-1420201301157513055751051424-1425251401309516065851151424-143232165150107250781001351624-184040165180120250851101451634-1850502032051403001001251601634-1865652222401803001201451801834-1880802412402103501351601952038-181001003053252203501551802152038-181251253563502304001852102452238-18150150394350320952102402802438-232002004574203809526529533526312-2325025053345042011032035540530312-2530030061052050811037541046030412-25PN252.5Mpa/PN404.0MpaDNd1LH1H2WED3FD2D1DbfN-Φ1515140110651304044565951624-1420201521157513051455751051624-1425251651309516058465851151624-143232180150107250664751001351824-184040200180120250764851101451834-1850502302051403008841001251602034-18656529024018030011041201451802238-18808031024021035012141351601952238-181001003503252203501504.51601902302438-231251254003502304001764.51882202702838-25150150480350320952044.52182503003038-25200200502420380952604.527831036034312-252502505684504201103134.533237042536312-303003006485205081103644.539043048540416-34PN646.4Mpa15151401106513040455751051824-1420201521157513051468901252024-18252516513095160584781001352224-183232180150107250664821101502424-234040200180120250764951251652434-2350502302051403008841051351752634-23656529024018030011041301602002838-23808031024021035012141401702103038-231001003503252203501504.51682002503238-25150150480350320952044.52402803403838-34200200502420380952604.530034540544312-342502505684504201103134.535240047048312-41)
