水流指示器是用于自動(dòng)噴水滅火系統(tǒng)中將水流信號(hào)轉(zhuǎn)換成電信號(hào)的一種水流報(bào)警裝置。水流指示器的作用是能夠及時(shí)報(bào)告火災(zāi)發(fā)生的部位。下面就讓
川消小編來(lái)為您講講水流指示器的檢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.
檢查要求
Inspection requirements
1.銘牌清晰、有操作指示標(biāo)識(shí)和產(chǎn)品說(shuō)明書(shū)。
1. The nameplate is clear, with safe operation instructions and product instructions.
2.有水流方向的性標(biāo)識(shí)。
2. There are signs indicating the direction of water flow.
3.各組件不得有機(jī)構(gòu)松動(dòng)、明顯的加工缺陷，表面不得有明顯銹蝕、圖層剝落、起泡、毛刺等缺陷；水流指示器槳片完好。
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.檢查水流指示器靈敏度，試驗(yàn)壓力為0.14~1.2MPa，流量不大于15.0L/min時(shí)，水流指示器不報(bào)警；流量在15.0~37.5L/min任一數(shù)值時(shí)，可報(bào)警可不報(bào)警，到達(dá)37.5L/min一定報(bào)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.為使系統(tǒng)維修時(shí)關(guān)停的范圍不致過(guò)大而在水流指示器入口前設(shè)置閥門(mén)時(shí)，要求該閥門(mén)采用信號(hào)閥，以便顯示閥門(mén)的狀態(tài)，其目的是為了防止因誤操作而造成配水管道斷水的故障。
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.當(dāng)1只噴頭啟動(dòng)或從末端試水裝置處放水時(shí)，水流指示器應(yīng)有信號(hào)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.水流指示器不動(dòng)作或信號(hào)不正常，可能是由于槳片被管腔內(nèi)雜物堵塞，調(diào)整螺母與觸頭未調(diào)整到位或電路接線脫落造成的，應(yīng)采取相應(yīng)的合理措施排除故障，如水流指示器管腔內(nèi)的雜物，將調(diào)整螺母與觸頭調(diào)整到位，檢查并重新將脫落電路接通等。
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.
安裝前，檢查管道試壓和沖洗記錄，對(duì)照?qǐng)D紙檢查、核對(duì)產(chǎn)品規(guī)格型號(hào)；目測(cè)檢查電器元件的安裝位置，開(kāi)啟試水閥門(mén)放水檢查水流指示器的水流方向。等等，注意事項(xiàng)了解的越多，就越順利使用，更多事項(xiàng)就來(lái)我們網(wǎng)站

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. Wait, the more you know about the precautions, the more smoothly you can use them. Come to our website for more precautions http://www.xintli.net Consult.
