蒸汽调节阀山西快乐十分APP下载因其使用介质的高温高压,故在选型时颇有讲究,如果选型不当,则会在使用过程中频频出现故障,严重影响设备和系统的正常运行。下面我们通过一个实例来谈谈蒸汽调节阀的选型及使用中需要注意的一些问题。

一家大型化工企业,需要用蒸汽来控制反应罐的温度,蒸汽来自热电厂的蒸汽余热,温度 200℃ 左右,压力 1.2MPa 左右,要求用蒸汽调节阀来控制蒸汽压力的恒定,阀门进口压力 0.8~1.0MPa,出口压力 0.4~0.5MPa。开始选型时,因为没有弄清楚现场参数,选用的是电动单座调节阀山西快乐十分APP下载,使用不久就故障频频,执行器电机烧坏、控制模块损坏、减速齿轮打坏的事,屡屡发生。
