自動噴水滅火系統施工容易忽略的細節，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:

自動噴水滅火系統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
產生原因及后果：達不到使用功能要求。
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在管道試壓和沖洗合格后進行，水流指示器的規格、型號應符合設計要求。
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水流指示器應使電器元件部位豎直安裝在水平管道上側，其動作方向應和水流方向一致；安裝后的水流指示器漿片、膜片應動作靈活，不應與管壁發生碰擦。信號閥應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.

自動噴水滅火系統信號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
產生原因及后果：信號閥不靈敏，甚不能顯示管中水流動的情況，且將其傳送給消防系統指揮中心。
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.
當水流指示器入口前設置控制閥時，應采用信號閥。
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信號閥應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.

自動噴水滅火系統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
產生原因及后果：焊接鋼管或無縫鋼管的管內鐵銹會造成噴灑頭堵塞，失去自動噴水滅火功能，加大火災損失。
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.

濕式報警閥下邊及水流指示器來水方向不裝信號閥而裝普通閥門
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
產生原因及后果：在維修管道時關閉閥門，維修后由于疏乎忘記打開，一旦發生火災管道內無水，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.
連接報警閥進出口的控制閥應采用信號閥。當不采用信號閥時，控制閥應設鎖定閥位的鎖具
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
