自動(dòng)噴水滅火系統(tǒng)施工容易忽略的細(xì)節(jié)，今天川消小編給大家整理如下：

The details that are easily overlooked in the construction of automatic sprinkler systems are summarized by the editor of Chuanxiao today as follows:

one

自動(dòng)噴水滅火系統(tǒng)噴灑水管的水流指示器安裝不符合要求

The installation of the water flow indicator of the sprinkler system's sprinkler pipe does not meet the requirements

產(chǎn)生原因及后果：達(dá)不到使用功能要求。

Causes and consequences: Failure to meet functional requirements for use.

水流指示器的安裝應(yīng)符合下列要求：

The installation of water flow indicators should meet the following requirements:

1水流指示器的安裝應(yīng)在管道試壓和沖洗合格后進(jìn)行，水流指示器的規(guī)格、型號(hào)應(yīng)符合設(shè)計(jì)要求。

The installation of the water flow indicator should be carried out after the pipeline pressure test and flushing are qualified, and the specifications and models of the water flow indicator should meet the design requirements.

2水流指示器應(yīng)使電器元件部位豎直安裝在水平管道上側(cè)，其動(dòng)作方向應(yīng)和水流方向一致；安裝后的水流指示器漿片、膜片應(yīng)動(dòng)作靈活，不應(yīng)與管壁發(fā)生碰擦。信號(hào)閥應(yīng)安裝在水流指示器前的管道上，與水流指示器之間的距離不宜小于300mm。

The water flow indicator should be installed vertically on the upper side of the horizontal pipeline at the electrical component part, and its action direction should be consistent with the water flow direction; After installation, the slurry and diaphragm of the water flow indicator should move flexibly and should not collide with the pipe wall. The signal valve should be installed on the pipeline in front of the water flow indicator, and the distance between it and the water flow indicator should not be less than 300mm.

自動(dòng)噴水滅火系統(tǒng)信號(hào)閥安裝在水流指示器的后邊，并相互直接連接

The signal valve of the automatic sprinkler system is installed behind the water flow indicator and directly connected to each other

產(chǎn)生原因及后果：信號(hào)閥不靈敏，甚不能顯示管中水流動(dòng)的情況，且將其傳送給消防系統(tǒng)指揮中心。

Causes and consequences: The signal valve is not sensitive and cannot even display the flow of water in the pipe, and it is transmitted to the fire control system command center.

當(dāng)水流指示器入口前設(shè)置控制閥時(shí)，應(yīng)采用信號(hào)閥。

When a control valve is set in front of the inlet of the water flow indicator, a signal valve should be used.

5.4.6信號(hào)閥應(yīng)安裝在水流指示器前的管道上，與水流指示器之間的距離不宜小于300mm。

5.4.6 The signal valve should be installed on the pipeline in front of the water flow indicator, and the distance between it and the water flow indicator should not be less than 300mm.

自動(dòng)噴水滅火系統(tǒng)使用非鍍鋅鋼管或連接噴灑頭支管使用管徑小于25mm的鍍鋅鋼管

The automatic sprinkler system uses non galvanized steel pipes or galvanized steel pipes with a diameter less than 25mm are used to connect the sprinkler branch pipes

產(chǎn)生原因及后果：焊接鋼管或無縫鋼管的管內(nèi)鐵銹會(huì)造成噴灑頭堵塞，失去自動(dòng)噴水滅火功能，加大火災(zāi)損失。

Causes and consequences: Rust inside welded or seamless steel pipes can cause blockage of the sprinkler head, loss of automatic sprinkler function, and increase fire losses.

短立管及末端試水裝置的連接管，其管徑不應(yīng)小于25mm。

The diameter of the connecting pipe for the short riser and the end water testing device should not be less than 25mm.

濕式報(bào)警閥下邊及水流指示器來水方向不裝信號(hào)閥而裝普通閥門

The lower part of the wet alarm valve and the water flow indicator are equipped with ordinary valves instead of signal valves in the direction of incoming water

產(chǎn)生原因及后果：在維修管道時(shí)關(guān)閉閥門，維修后由于疏乎忘記打開，一旦發(fā)生火災(zāi)管道內(nèi)無水，造成重大損失。

Causes and consequences: When repairing the pipeline, the valve was closed. However, due to carelessness and forgetting to open it after maintenance, in the event of a fire, there is no water in the pipeline, causing significant losses.

連接報(bào)警閥進(jìn)出口的控制閥應(yīng)采用信號(hào)閥。當(dāng)不采用信號(hào)閥時(shí)，控制閥應(yīng)設(shè)鎖定閥位的鎖具

The control valve connecting the inlet and outlet of the alarm valve should use a signal valve. When signal valves are not used, control valves should be equipped with locks that lock the valve position
