Product analysis of Shijiazhuang three - way regulating valve
The author: Time:2020/6/29

  三通阀调节阀的三个进出口与管道相连,相当于两台单阀座调节阀与一个三通合为一体。按其作用方式分为合流阀与分流阀两种,三通阀多为由单阀座体改型加工而成,其为双阀芯和双阀座,阀芯为套简形,利用阀座与筒形阀芯自身导向。两个带窗口的套简形阀芯由一根轴杆串联起来,当一路处于全开,另一路就是全关。
  由于两路流体压差相差较大时,不平衡力也较大(同单座阀相似),两阀芯做上或下移动时,两路流体量是成比例关系变化的。合流阀一般为两路进口量之和等于出口流量,即A% + B% = 100%;分流阀的进口流量等于两路出口流量之和,即100%= A% + B%。分流阀的流通总是为100%状态,只是两个分量之间按比例变化。泄漏量同双座阀一样较大。三通阀适用于压差不大,洁净的流体介质,如热交换器的冷热流量调节,泵的出口稳压回流调节,简单的配比调节场合。
