工作原理
安装说明
1、在比例式减压阀安装前应将管道冲洗干净并在阀前加装 Y 型过滤器由于管道内细小的杂物都将会导致减压阀关闭不严从而引起渗漏而失效导致阀后管网静压超高。 过滤器应设置在总管上并去掉堵头引出装有阀门的排水管至污水池以便及时排污。
2、比例式减压阀前后必须设置闸阀或蝶阀以便检修时切断水源。
3、比例式减压阀宜垂直安装。 其安装说明书上说可垂直安装也可水平安装但当水平安装时由于重力作用会造成下部的偏心磨损因此宜垂直安装并应按阀体上所示箭头方向安装。 江银大厦消火栓给水自动喷淋系统比例式减压阀均采用垂直安装减压明显功能正常。
4、在高层建筑消防给水中为保证供水的不间断性减压阀组宜设计为两组同径并联其中一组工作一组备用。 且应与前后管径相同以便检修更换时不影响供水。
5、消防给水系统中比例式减压阀不宜设置旁通管。 在江银大厦消火栓系统减压阀施工中初期安装了旁通管在使用约一年半后季检时发现阀后压力表与阀前压力表数值相同打开试验阀放水试验测试压力则又显示正常而后检查时发现是由于设于旁通管上的阀门胶衬老化导致渗漏而出现静压失常动、压正常的现象。 所以为保证消防给水系统的供水可靠性,本人认为不应设置旁通管。
6、在比例式减压阀前后宜装设压力表可直接用于观察减压阀前后压力的变化监察减压阀的减压效果和工作情况。
7、在高层建筑消火栓系统的比例式减压阀后一般宜设置可曲挠橡胶接头。 一方面为便于减压阀安装拆卸同时亦可起到伸缩节作用。
