3.应及时排除管道中的积气。当空气进入减压管网或管网内随压力变化时气体从水中析出，这时区域内用户的水压极不稳定；处在供水zui不利点用水器更是压力变化急骤，有减压阀时呈现虚假的峰值压力，有时还会抽吸断水，还有管网会伴随撞击声。产生这种现象，会影响燃气热水器、电热水器等稳定工作，严重时会被毁坏；对各种盥洗器具的进水连接管破坏力也很大，因此爆管的事件屡有发生；有些水表无法正确计量，出现用户不用水，水表也会不断地转动。为杜绝这类事故，应检查屋顶水箱生活给水总管的蓄水高程是否满足，如不满足水箱出水口处会产生水旋，吸入空气。排除这一故障可调整水箱内液位控制器的zui低水位高程，经验表明一般zui低水位距出水口应不小于0.3m。也可反复开启设置在分区、减压系统两侧的压力表放气旋塞，把已进入管网内的空气徐徐排出。如采取上述措施后，在分区总管末梢以下的一些用水器还出现上述现象，可以在这些部位增设自动排气装置。

4.注意减压阀的减压保障系统。无论选用比例式还是可调式减压阀，其减压比P1∶P2不宜选择过大，一般应控制在5∶1之内。超过这个范围易产生气蚀现象，损坏阀件，产生啸叫噪音。有些活塞式减压阀，制造厂在其阀体上加工一个直径1.5mm左右的小孔，其功能是让阀芯运动时起到透吸气作用，维护管理时应注意千万不要将小孔塞住，否则影响减压阀的正常运行。

这种类型执行机构的主要优点是所有部件都安装在一个壳体内，在这个防水、防尘、防爆的外壳内集成了所有基本及*的功能。主要缺点是，当电源故障时，阀门只能保持在原位，只有使用备用电源系统，阀门才能实现故障安全位置（故障开或故障关）

5.加强减压阀保障系统的管理巡视，要注意观察减压阀本身的工作动态。阀前、阀后压力数值接近，表明减压阀本身已存在故障。即活塞式减压阀的阀芯与阀体间的平面密封橡胶件损坏；薄膜式可调型减压阀主阀膜片有裂痕和O型圈损坏，及导阀连通管堵塞，造成减压阀减压作用削弱或者失效。这对分区管网危害*，特别是许多用水设备可能因超压力而出现爆管，必须及时修复。比例式(活塞型)减压阀阀体上的透吸气小孔如出现滴漏不止，表明阀芯上几档O型密封圈已经磨损，要更换密封件。但在修理拆装减压元件时，要谨慎细心，调换内密封件；清理杂物时，应因势利导，不要用金属棒、硬梗撬阀

减压阀的活动部位，使用木榔头和木柄敲击震动，慢慢拆卸阀内部件。修理完毕后重新安装时，一定要和阀门上的流向指示保持*。
6.注意检查比例式减压阀的安装位置。高层内减压阀设计安装的位置不妥，会出现减压阀阀后压力忽高忽低，管网压力严重偏离允许范围，伴随毁坏淋浴器，水管爆裂和损坏用户水表等事故发生；有时也会水流不畅，分区内出现无规律的断水现象，影响用户用水。出现类似事故，检查整个减压阀减压分区给水系统，无疑点可找；拆卸减压阀过滤器等元件并无异常；有些物业管理单位甚至怀疑减压阀的技术性能，多次调换新的减压阀，也不能解决问题。这时可从检查比例减压阀设计安装位置是否合理着手，认真检查管网系统是否存在等位倒虹管现象，即分区的输出管路标高相近。此类情况在主、副楼同一屋顶水箱，下给水供水系统中很容易出现。发现这些问题，可以考虑把比例减压阀安装位置提高一个层面(不能提得太高，必须顾全分区内用水设备的承压规范要求)；也可在主、副楼内，分设两组独立的比例减压阀给水系统。
