真空破坏阀(Vacuum Breaker Valve)是一种安全阀。主要用于容器或管道中,在管道或容器因系统运行或停止而产生负压或真空逐步升高时,该阀能自动开启,破坏真空效应,使管道及其它设备不至产生瘪、凹裂等现象,以保护设备的安全。
发展历史
*代气压式
原始的气压式真空破坏阀由于需要专门的气源和直流设备,已逐步淘汰。
第二代电动式
第二代的电动式真空破坏阀同水泵同通电,断电。一旦出现非事故的停电,此阀就能自动马上打开,破坏虹吸,截断水流,防止水流倒灌会产生主机的叶轮飞扬的事件。
此阀门关闭动力源是采用100%节能电磁铁,工作电源是采用220V,50Hz,其维护工作电压只要300毫安。能长时间工作,电磁铁的温升只要10K。开阀动力采用蓄能弹簧,能在2~5秒之间打开。还设有手动开阀、关阀的装置。人工操作方便、安全系数大。
但由于此阀耗电且一旦其电路发生故障即*失效,所以也没有*得到市场的认可。
第三代机械式
第三代真空破坏阀为机械式结构。在系统形成真空时由大气压力直接顶开挡板往系统加气,迅速破坏真空,防止负压危害。0.2bar的密封压力保证了在系统正压时*不渗漏。由于不需要耗电,使用寿命长,破真空及时而得到市场的*欢迎。
