NKZ61H/Z64H焊接式真空闸阀焊接式真空闸阀和真空截止阀是同属一个类型的阀门，区别在它的关闭件是个阀体，阀体绕阀体中心线作旋转来达到开启、关闭的一种阀门。闸阀在管路中主要用来做切断、分配和改变介质的流动方向。真空截止阀的工作原理是靠旋转阀恋来使阀门畅通或闭塞。闸阀开关轻便，体积小，可以做成很大口径，密封可靠，结构简单，维修方便，密封面与球面常在闭合状态，不易被介质冲蚀，在各行业得到广泛的应用。主要性能规范Chiefpropertyandspecification焊接式真空闸阀-试验压力TestpressureJ65Y直流式对焊截止阀J65Y直流式对焊截止阀产品特点：高温高压直流式对焊截止阀,直流式对焊截止阀,高温高压截止阀BJ41H保温截止阀BJ41H保温截止阀主要用于石油、化工、冶金、制药等各类系统中，以输送常温下会凝固的高粘度介质BJ45H直流式保温截止阀直流式保温截止阀，BJ45H保温截止阀，该阀适用于化工、化肥行业的管路上，夹套内涵入蒸汽能防止介BJ41Y锻钢保温截止阀锻钢保温截止阀，BJ41Y保温截止阀，BJ41Y锻钢截止阀J641H气动截止阀J641H气动截止阀本阀采用双作用气缸，利用上腔进气或者下腔进气来远距离控制阀门，操作方便、灵活J41W法兰不锈钢截止阀J41W法兰不锈钢截止阀的阀杆轴线与阀座密封面垂直。阀杆开启或关闭行程相对较短，J41W截止阀具有公称压力PN/MPaNominalpressure试验压力/MPaSealtest壳体强度试验Shellslrenghttest上密封试验BackSealtest密封试验Seattest2.53.82.82.84.O6.04.44.46.49.6707.O1O.O15O11.O11.O·焊接式真空闸阀-使用范围Applicable产品类型Productcalssification适用介质Applicablemedium适用温度/℃ApplicabletemperatureNKZ61HNKZ64HH-C型NKZ964HH-C型NKZ961H水、蒸汽、空气Water，Steam，Air≤425NKZ61HNKZ64HY-I型NKZ964HY-I型NKZ961H水、蒸汽、空气Water，Steam，Air≤550·焊接式真空闸阀-主要零部件材料Materialsformainparts零件名称Partname阀体、阀盖BodyBonnet阀杆Valvestem闸板Wedgegate密封面Sealingface阀杆螺母ValveYokenut填料Parking紧固件FastenerNKZ61HNKZ64HH-C型NKZ964HH-C型NKZ961HWCB2Crl325H：合金钢H：alloysteel铝青铜Albronze膨胀复合石墨Expandingcompoundgraphite优质碳钢High-gradecarbonsteelNKZ61HNKZ64HY-I型NKZ964HY-I型NKZ961H铬钼钢Cr.Mosteel20CrlMo1VA铬钼钢Cr.MosteelY：硬质合金Y：carbidealloy铬钼钢Cr.Mosteel·焊接式真空闸阀-主要尺寸及重量Maindimensionsandweight公称通径DN/mmNominaldiamecer公称压力PN/MPaNominalpressure主要外形尺寸和连接尺寸/mmMainexternalandconnectingdimensions重量/kgWeightLHDD0∝W502.5250345644937o30'2502465270395826637o30'2503680280425957837o30'3005210030051O11710037o30'3006712532557014412537o30'3509515035072517215137o30'35013520040082022320137o30'40021025045089027825337o30'450300300500107033030337o30'550395350550132038235137o30'650530400600145043239837o30'750685450650156048445037o30'750906500700172053549837o30'8501130600809188063860037o30'9001387700900208373870037o30'95018948001OOO259084080037o30'10002621504.0250345644837o30'3003065270395826637o30'3004280280425957837o30'3505710030051O1171OO37o30'3507512532557014412537o30'40010515035072517215137o30'40015020040082022319937o30'45023225045089027825137o30'550330300500107033030137o30'650430350550132038234937o30'750570400600145043239637o30'850730506.4250350644837o30'3003465280405826537o30'3004880310435957637o30'350651003505151179837o30'4008112540058015012837o30'40011215045073517214937o30'45016120055083522319737o30'55025525065090527824537o30'650390300750108033029337o30'750515350850134038234137o30'800695400950146043238637o30'900885501O.0250350644837o30'3003765280405826337o30'3005280310435957437o30'350701003505151179737o30'4008612540058015012437o30'40011815045073517214437o30'45016820055083522318937o30'55026325065090527823537o30'650405300750108033028137o30'750536350850134038233337o30'850732400950146043237637o30'950947注：PN2.5(25)型阀门允许作为PN1.0(10)、PN1.6(16)压力级选用·焊接式真空闸阀-主要尺寸Maindimensions公称通径DN/mmNominaldiamecer公称压力PN/MPaNominalpressure主要外形尺寸和连接尺寸/mmMainexternalandconnectingdimensions电动装置ElectricdeviceLHDD0∝W502.5250618644937o30'562DZWlO
