ZAZ(Q、X)电动三通合流(分流)调节阀
调节阀概述ZAZQ(X)型电动三通合流(分流)调节阀有合流和分流二种型式,由DKZ电动执行机构和三通合流或三通分流调节组成,以电源为动力,接受统一的标准信号0~10mADC或4-20mADc驱使阀门开度与此操作信号相对应。合流阀的作用是将一种流体分成两路流体。分流合流阀只能对应选用,但当DN≤80时,合流阀可用于分流场合。可替代两台单、双座调节阀,节省***,占据空间小。三通调节阀通常用于热交换器的两种介质调节,及简单的配比调节。调节阀主要技术参数公称通径mm合流253240506580100125150200250300分流80100125150200250300额定流量系数Kv合流8.513213452851352103405358001260分流851352103405358001260公称压力MPa1.64.06.0流量特性直线执行机构Ⅱ型DKZ-310DKZ-310DKZ-410DKZ-510DKZ-510Ⅲ型DKZ-510CDKZ-310CDKZ-410CDKZ-510CDKZ-510C出轴推力(N)4000400064001600016000行程mm16254060100上阀盖型式1.61.02.51.61.51.00.650.40.30.160.260.18允许压差(MPa)普通式(常温型),热片式(中温型)介质温度℃-20~+200、-40~+250(常温型)-40~+450(中温型)可调比30:1法兰标准铸铁按JB78-59,铸铜按JB79-59输入阻抗Ⅱ型:200Ⅲ型:250出厂状态电开(对上阀座而言),如需电关,订货时应注明调节阀性能指标项目指标值基本误差%≤&plu***n;3.5回差%≤2.5死区%≤3.0始终点偏差%电开、电关&plu***n;2.5&plu***n;2.5允许泄量L/H1×10-3×阀额定容量调节阀外形尺寸公称通径DNALHH1分流合流PN1.6PN4.0PN6.4分流合流PN1.6PN4.0PN6.4PN1.6PN4.0PN6.4普通型热片型普通型热片型2552049018519020071586514015016032520490200210210721871150160170405204902202302357338831601701805052049025025526574889818019020065520520275285295839999200220220805205203053103208721032842100222525026521023024010052052035035537089610568461006245275285220250260125520520410425440947116289711122843203252603003001505205204504604759471162897111230534034028032032020052052055056057096511809051120350400410320380380250520520670740750300520520770805820订货须知订货时请注明:1、产品型号2、公称通径3、公称压力4、使用介质5、输入信号6、流量系数7、阀体材质8、附件)
