ZJHF(H)气动三通调节阀
价格:100.00
ZJHF(H)气动三通调节阀有合流和分流两种结构形式。阀芯结构采用圆筒薄壁窗口,并采用阀芯侧面导向,三通阀在某些场合可以替代两个二通阀和一个三通接管而等到广泛应用,常用于热交换器的两相调节,也可用于简单的配比调节。公称通径和压差较小时,合流阀可用于分流场合,可互换使用,但公称通径大于80mm和压差较大的分流场合,不能互换使用。一、阀体阀体形式:三通铸造球型阀公称通径:25—300mm公称压力:PN1.64.06.4MPa连接形式:法兰式按JB78-59JB79-59材料:HT200ZG230—450ZG1Cr18Ni9TiZG0Cr18Ni12Mo2Ti二、上阀盖常温型:-20~+200℃散热型:-40~+450℃压盖形式:螺栓压紧式填料:V型聚四氟乙烯填料,柔性石墨。三、阀内组件阀芯型式:V型缺口芯流量特性:线性或等百分比材料:1Cr18Ni9Ti0Cr18Ni12Mo2Ti四、执行机构型式:多弹簧式薄膜执行机构膜片材料:丁晴橡胶夹增强涤纶织物弹簧范围:0.02~0.1、0.04~0.20MPa供气压力:0.140.160.28MPa气源接头:M10×1环境温度:-30~+70℃五、性能泄漏量:符合标准ANSIB16.104IV级,小于额定Kv值的0.01%基本误差:±1%回差:1%(带定位器)3%(不带定位器)线性:±1%(带定位器)±5%(不带定位器)备注:使用V型聚四氟乙烯填料可调范围:30:1六、流量系数Kv值和行程公称通径(mm)253240506580100125150200250300阀座直径(mm)20253240506580100125150200250300额定Kv值合流阀6.38.513213452851352103405358001280分流阀1352103405358001280额定行程(mm)16254060100七、允许压差值1、气动三通薄膜合流阀执行机构供气压力MPa弹簧范围MP定位器允许压差(MPa)阀座直径(mm)202540506580100125150HA20.140.02~0.10有0.790.490.330.200.120.090.05--0.350.08~0.240.041.63.50.992.3(0.67)1.40.390.86(0.24)0.62(0.18)0.34(0.10)--HA30.140.02~0.10--0.590.350.220.160.090.050.040.350.08~0.24--4.0(1.2)2.50.711.53(0.43)1.1(0.31)0.02(0.18)0.30(0.10)0.27(0.08)HA40.140.02~0.10----0.370.260.150.100.060.350.08~0.24----2.7(0.76)1.9(0.54)1.07(0.30)0.69(0.20)0.47(0.13)备注:①下面数字为分流场合压差,其余为合、分流相同2、气动三通薄膜分流阀执行机构供气压力弹簧范围定位器允许压差(MPa)阀座直径(mm)80100125150HA20.140.02~0.10有0.090.05--0.350.08~0.24有0.620.34--HA30.140.02~0.10有0.160.090.050.040.350.08~0.24有1.10.620.390.27HA40.140.02~0.10有0.260.150.100.060.350.08~0.24有1.91.070.690.47八、法兰距离和外形尺寸公称通径DN合流(ZJHH)分流(ZJHF)?ALH2H1LH2H1PN(MPa)PN(MPa)PN(MPa)PN(MPa)1.64.06.4常温中温1.64.06.41.64.06.4常温中温1.64.06.425285185190200615763140150160185190200615763140150160322852002002106227731501601702002002106227731501601704028522022023562577616017018022022023562577616017018050285250255265640791180190200250255265640791180190200653602752852958611024200210220275285295861102420021022080360300310320879104221023024030031032088510502252502651003603503603708731036220250260350360370900106024527528512547041043044010291244260300300410425440105012652853203251504704504654751046126128032032045046047510601275305340345200470550560570107512903203803805505605701105132035040041025060063566067014511641474474635660670150528003006007207407701512176058458472074077015451820九、型号编制说明ZJHF16CGK自控阀门执行机构:执行机构:阀门结构类型:公称压力:阀体材质:温度类型:作用型式:J:表示精小型多弹簧气动薄膜F:表示分流阀16:表示1.6MPaC:表示碳钢G:中温型常温省略K:表示气开型N:表示合流阀25:表示2.5MPaP:表示碳钢B:表示气关型M:表示角形阀40:表示4.0MPa64:表示6.4MPa)
