沟槽管件在消防水系统中具有应用The application of trench pipe fittings in the water proof system
1、自喷系统安装前应对压力开关、水流指示器、信号阀、报警阀等自动监测装置,逐个进行主要功能的检查,不合格者
不得使用。
2、吊顶内的管道安装应与空调、电气等管线的位置协调好,各专业]:序安装应有总体安排。
3、报警阀的安装应设在明显、易于操作的位置,距地高度为1.2m。
4、自喷管道的固定支架安装,支吊架的位置以不妨碍喷头喷水效果为原则,一般吊架距喷头应大于300mm,距末端喷头
的距离不大于750mm。
5、水流指示器的安装控制措施,应水平安装,前后应保持有5倍安装管径长度的直管段,注意指示器的水流方向,及电
接点有良好的接触。
6、消防水管进入消防箱应“横平竖直”,不应斜进箱内;消火栓口应垂直朝外,阀门中心距地1.1m。
7、消防管道试压可分层分段进行,对不能参与试压的设备、仪表、附件应加以隔离。
8、管道的冲洗是在管道试压完毕后,可连续做冲洗工作。承包单位应做好试压和冲洗记录。
1. The automatic monitoring device such as pressure switch, water flow indicator, signal valve and alarm valve should be monitored before the installation of the self injection system, and the main functions are checked one by one, and the unqualified people are not qualified.
No use.
2. The installation of pipes in the ceiling should be coordinated with the location of air conditioning, electrical and other pipelines.
3, the installation of alarm valve should be located in an obvious and easy to operate position, and the height from the ground is 1.2m.
4. The fixed support of the self spray pipe is installed. The position of the support hanger does not prevent the sprinkler effect as the principle. The general hanger distance nozzle should be more than 300mm and the nozzle is away from the end nozzle.
The distance is not more than 750mm.
5. The installation and control measures of the water flow indicator should be installed horizontally, and the straight pipe section with 5 times the length of the pipe diameter should be kept before and after, and the direction of water flow and the electricity should be paid attention to.
The contact has a good contact.
6, the fire hoses should enter the fire box to be "horizontal and vertical", and should not be tilted into the box. The fire hydrant should be perpendicular to the outside and the center of the valve is 1.1m away from the ground.
7, the fire pipe pressure test can be divided into layers, and the equipment, instruments and accessories that can not participate in the test should be isolated.
8. The flushing of the pipeline can be done continuously after the completion of the pipeline pressure test. The Contractor shall make a good record of test pressure and flushing.
