自动喷水灭火系统施工容易忽略的细节，今天
川消小编给大家整理如下：
The details that are easily overlooked in the construction of automatic sprinkler systems are summarized by the editor of Chuanxiao today as follows:

one
自动喷水灭火系统喷洒水管的水流指示器安装不符合要求
The installation of the water flow indicator of the sprinkler system's sprinkler pipe does not meet the requirements
产生原因及后果：达不到使用功能要求。
Causes and consequences: Failure to meet functional requirements for use.
水流指示器的安装应符合下列要求：
The installation of water flow indicators should meet the following requirements:
1水流指示器的安装应在管道试压和冲洗合格后进行，水流指示器的规格、型号应符合设计要求。
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水流指示器应使电器元件部位竖直安装在水平管道上侧，其动作方向应和水流方向一致；安装后的水流指示器浆片、膜片应动作灵活，不应与管壁发生碰擦。信号阀应安装在水流指示器前的管道上，与水流指示器之间的距离不宜小于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.

自动喷水灭火系统信号阀安装在水流指示器的后边，并相互直接连接
The signal valve of the automatic sprinkler system is installed behind the water flow indicator and directly connected to each other
产生原因及后果：信号阀不灵敏，甚不能显示管中水流动的情况，且将其传送给消防系统指挥中心。
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.
当水流指示器入口前设置控制阀时，应采用信号阀。
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信号阀应安装在水流指示器前的管道上，与水流指示器之间的距离不宜小于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.

自动喷水灭火系统使用非镀锌钢管或连接喷洒头支管使用管径小于25mm的镀锌钢管
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
产生原因及后果：焊接钢管或无缝钢管的管内铁锈会造成喷洒头堵塞，失去自动喷水灭火功能，加大火灾损失。
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.
短立管及末端试水装置的连接管，其管径不应小于25mm。
The diameter of the connecting pipe for the short riser and the end water testing device should not be less than 25mm.

湿式报警阀下边及水流指示器来水方向不装信号阀而装普通阀门
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
产生原因及后果：在维修管道时关闭阀门，维修后由于疏乎忘记打开，一旦发生火灾管道内无水，造成重大损失。
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.
连接报警阀进出口的控制阀应采用信号阀。当不采用信号阀时，控制阀应设锁定阀位的锁具
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
