调节阀选型指南之—弹簧范围的选择一、“标准弹簧范围”的错误说法应予纠正弹簧是气动调节阀的主要零件。
弹簧范围是指一台调节阀在静态启动时的膜室压力到走完全行程时的膜室压力,字母用Pr表示。
如Pr为20~100KPa,表示这台调节阀静态启动时膜室压力是20KPa,关闭时的膜室压力是100KPa。
常用的弹簧范围有20~100KPa、20~60KPa、60~100KPa、60~180KPa、40~200KPa…由于气动仪表的标准信号是20~100KPa,因此传统的调节阀理论把与气动仪表标准信号一致的弹簧范围(20~100KPa)定义成标准弹簧范围。
调节阀厂家按20~100KPa作为标准来出厂,这是十分错误的。
为了保证调节阀正常关闭和启动,就必须用执行机构的输出力克服压差对阀芯产生的不平衡力,我们知道对气闭阀膜室信号压力首先保证阀的关闭到位,然后再继续增加的这部分力,才把阀芯压紧在阀座上克服压差把阀芯顶开。
我们又知道,不带定位器调节阀的最大信号压力是100KPa,它所对应的20~100KPa的弹簧范围只能保证阀芯走到位,再也没有一个克服压差的力量,阀门工作时必然关不严造成内漏。
为此,就必须调整或改变弹簧范围,但是,把它说成“标准弹簧范围”就出问题了,因为是标准就不能改动。
如果我们坚持标准,按“标准弹簧范围”来调整,那么,它又怎么能投用呢?在现实中,却有许多使用厂家和安装公司;都坚持按“标准弹簧范围”20~100KPa来调整和验收调节阀,又确实发生阀门关不严的问题。
错误的根源就在此。
正确的提法应该是“设计弹簧范围”,是我们设计生产弹簧的零件参数。
工作时根据气开气闭还要作出相应的调整,我们称为工作弹簧范围。
仍以上述为例,设计弹范围20~100KPa,对气闭阀我们可以将工作弹簧范围调到10~90KPa,这样就有10KPa,作用在膜室的有效面积Ae 上;又如气开阀,有气打开,无气时阀关闭,此时克服压差靠的是弹簧的预紧力。
