水流指示器是用于自动喷水灭火系统中将水流信号转换成电信号的一种水流报警装置。水流指示器的作用是能够及时报告火灾发生的部位。下面就让川消小编来为您讲讲水流指示器的检查及其他方面的要求吧。

Water flow indicator is a kind of water flow alarm device used to convert water flow signal into electrical signal in automatic sprinkler system. The function of the water flow indicator is to report the location of the fire in time. Let's talk about the inspection of water flow indicator and other requirements.

检查要求

Inspection requirements

1.铭牌清晰、有操作指示标识和产品说明书。

1. The nameplate is clear, with safe operation instructions and product instructions.

2.有水流方向的性标识。

2. There are signs indicating the direction of water flow.

3.各组件不得有机构松动、明显的加工缺陷，表面不得有明显锈蚀、图层剥落、起泡、毛刺等缺陷；水流指示器桨片完好。

3. All components shall be free of loose mechanism, obvious processing defects, and obvious rust, layer peeling, blistering, burr and other defects on the surface; The paddle of water flow indicator is intact.

4.检查水流指示器灵敏度，试验压力为0.14~1.2MPa，流量不大于15.0L/min时，水流指示器不报警；流量在15.0~37.5L/min任一数值时，可报警可不报警，到达37.5L/min一定报警。

4. Check the sensitivity of the water flow indicator. When the test pressure is 0.14~1.2mpa and the flow is not greater than 15.0l/min, the water flow indicator does not alarm; When the flow is at any value from 15.0 to 37.5l/min, it can alarm or not, and it will alarm when it reaches 37.5l/min.

其他

other

1.为使系统维修时关停的范围不致过大而在水流指示器入口前设置阀门时，要求该阀门采用信号阀，以便显示阀门的状态，其目的是为了防止因误操作而造成配水管道断水的故障。

1. In order to ensure that the shutdown range during system maintenance is not too large, when setting a valve in front of the inlet of the water flow indicator, it is required to use a signal valve to display the status of the valve, in order to prevent the water supply failure of the water distribution pipeline caused by misoperation.

2.当1只喷头启动或从末端试水装置处放水时，水流指示器应有信号返回消防控制中心。

2. When one nozzle is started or water is discharged from the end water test device, the water flow indicator shall have a signal to return to the fire control center.

3.水流指示器不动作或信号不正常，可能是由于桨片被管腔内杂物堵塞，调整螺母与触头未调整到位或电路接线脱落造成的，应采取相应的合理措施排除故障，如水流指示器管腔内的杂物，将调整螺母与触头调整到位，检查并重新将脱落电路接通等。

3. The water flow indicator does not act or the signal is abnormal, which may be caused by the blade being blocked by debris in the lumen, the adjusting nut and contact are not adjusted in place, or the circuit wiring falls off. Corresponding reasonable measures should be taken to eliminate the fault, such as removing debris in the lumen of the water flow indicator, adjusting the adjusting nut and contact in place, checking and reconnecting the fallen circuit, etc.

安装前，检查管道试压和冲洗记录，对照图纸检查、核对产品规格型号；目测检查电器元件的安装位置，开启试水阀门放水检查水流指示器的水流方向。等等，注意事项了解的越多，就越顺利使用，更多事项就来我们网站http://www.cx-fire.com咨询吧。

Before installation, check the pipeline pressure test and flushing records, and check and check the product specifications and models against the drawings; Visually check the installation position of electrical components, open the water test valve and drain water to check the water flow direction of the water flow indicator.
