请教：如何 进行消火栓栓口静水压力和栓口出水压力的测量？
推荐回答（3个）
使用“消火栓压力试验装置”测试静压及动压
消火栓系统试水检测装置是用于检测室内消火栓的静水压，出水压力，并校核水枪充实水柱的专用装置。
a.测量消火栓栓口的静水压和出水压。现行国家规范中室内消火栓栓口的静水压力不应大开0.8Mpa；消火栓栓口的出压力不应大于0.5Mpa。此外在《高层民用建筑设计防火规范GB50045—95》中还对高层建筑最不利点消火栓的静水压做了如下规定：
建筑高度不超过100米时，高层建筑最不利点消火栓静压不应低于0.07Mpa建筑高度超过100米时，高层最不利点消火栓静水压力不应低于0.15Mpa。
b.校核水枪充实水柱。对于建筑物内的消火栓水枪的充实水柱，一般不应小于7米，但甲、乙类厂房，超过六层的民用建筑，超过四层的厂房及库房内充实水柱不应小于10米；高层工业建筑，高架库房内，水枪充料水柱不应小于13米。对于高层民用建筑，建筑高度不超过100米的高层建筑，消防水枪的充实水柱不应小于10米，建筑高层超过100米的高层建筑，充实水柱不应小于13米。
主要性能参数：
a.型号ZN17-SSZ1型；
b.公称通径：65mm
c.公称压力：1.0 Mpa;
d.压力表量程:0~1.6Mpa;
e.压力表精度:1.5级.
使用方法
a.消火栓栓口静水压的测量
(a)将ZN17-SSZ1型试水检测装置连接到火栓栓口；
(b)安装好压力表，并调整压力表检测位置使之竖直向上；
(C)在ZN17-SSZ1型度水装置出口处装上端盖；
(d)缓慢打开消火栓阀门，压力表显示的什为消火栓栓口的静水压(Mpa)；
(e)测量完成后，关闭消火栓阀门，旋松压力表，使ZN17-SSZ1型试水检测装置内的水压泄掉，再取下端盖。
b.消火栓栓口出水压力的测量。
(a)将水带连接到消火栓栓口；
(b)将水带接到ZN17-SSZ1型试水检测装置的进口；
(c)打开消火栓阀门放水此时不应压折水带，压力表显示的水压即为消火栓栓口的水压力。
c.通过ZN17-SSZ1型试水检测装置校核水枪的实水柱可以采取以下的连接的方式：
消火拴口→水带→ZN17-SSZ1型试水检测装置
打开消火栓阀门放水，此时水枪充实水柱与试水检测装置上的压力表的显示的栓口出水压力之对应关系见下表
序号 充实水柱(m) 流量(L/S) 栓口出水压力(Mpa)
1 7 3.8 0.09
2 10 4.6 0.135
3 13 5.4 0.186
注意事项
a.测量时，特别是在测量栓口静压时，开启阀门应缓慢，避免压力冲击造成检测装置损坏；
b.静压测量完成后，折下端盖缓慢旋下端盖泄压；
c.测量出口压力和充实水柱时，应注意水带不应有弯折；
d.ZN17-SSZ1型消火栓试水检测装置使用后，应将水擦净放回。
消火栓栓口静水压力可用压力表，当然可用总管上的压力表，但要考虑位置差的静水压。栓口出水压力的测量通过试射充实水柱长度决定。
