Y43H先导活塞式蒸汽减压阀
价格:965.00
Y43H/Y型先导活塞式蒸汽减压阀由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化,通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小,实现减压稳压功能。主产品主要用于蒸汽管路,起减压稳压作用。【结构图】【主要连接尺寸】单位:mm外形尺寸(PN6.4-16.0):公称通径DNY43H/Y型减压阀外形尺寸LHHl6.4MPa10.0/16.0MPa151801803051052018020034010525200220340120322202303401204024024035513550270300355135653003403601408033036039517100380400185125450415215150500430225200550495260250650545310300800600355350850640395400900690435500950780495外形尺寸(PN1.6-4.0):公称通径DNY43H/Y型先导式减压阀外形尺寸LHHl1.6/2.5MPa4.0MPa15160180295902016018033098251802003301103220022033011040220240345125502502703451256528030035013080310330385160100350380385170125400450400200150450500415210200500550475240250650525290300800580335350850620375400900660405450900730455500950750465◆连接形式:☆法兰式:RFFMRJ☆执行标准:JB79GB9113ANSIB16.5【主要技术参数和性能指标】Y43H蒸汽减压阀公称压力(Mpa)1.62.54.06.410.016.0壳体试验压力(Mpa)*2.43.756.09.615.024密封试验压力(Mpa)1.62.54.06.410.016.0最高进口压力(Mpa)1.62.54.06.410.016.0出口压力范围(Mpa)0.1-1.00.1-1.60.1-2.50.5-3.50.5-3.50.5-4.5流量特性偏差(Mpa)P2GGB12246-1989压力特性偏差(Mpa)△P2PGB12246-1989最小压差(Mpa)0.150.150.20.40.81.0渗漏量GB12245-1989*:壳体试验不包括膜片、顶盖【主要零部件材料】Y43H/Y型蒸汽减压阀零件名称零件选用材料阀体阀盖底盖WCB阀座阀盘2Cr13缸套2Cr13/25(镀硬铬)活塞2Cr13/铜合金活塞环合金铸铁导阀座导阀杆2Cr13膜片1Cr18Ni9Ti主阀弹簧50CrVA导阀主弹簧50CrVA调节弹簧60Si2Mn【流量系数(Cv)】DN1520253240506580100125150200250300350400500Cv12.546.591625366410014025040057078010201500)
