溝槽管件在消防水系統(tǒng)中具有應(yīng)用The application of trench pipe fittings in the water proof system
1、自噴系統(tǒng)安裝前應(yīng)對壓力開關(guān)、水流指示器、信號閥、報警閥等自動監(jiān)測裝置，逐個進(jìn)行主要功能的檢查，不合格者
不得使用。
2、吊頂內(nèi)的管道安裝應(yīng)與空調(diào)、電氣等管線的位置協(xié)調(diào)好，各專業(yè)]：序安裝應(yīng)有總體安排。
3、報警閥的安裝應(yīng)設(shè)在明顯、易于操作的位置，距地高度為1.2m。
４、自噴管道的固定支架安裝，支吊架的位置以不妨礙噴頭噴水效果為原則，一般吊架距噴頭應(yīng)大于300mm，距末端噴頭
的距離不大于750mm。
5、水流指示器的安裝控制措施，應(yīng)水平安裝，前后應(yīng)保持有5倍安裝管徑長度的直管段，注意指示器的水流方向，及電
接點(diǎn)有良好的接觸。
6、消防水管進(jìn)入消防箱應(yīng)“橫平豎直”，不應(yīng)斜進(jìn)箱內(nèi)；消火栓口應(yīng)垂直朝外，閥門中心距地1.1m。
7、消防管道試壓可分層分段進(jìn)行，對不能參與試壓的設(shè)備、儀表、附件應(yīng)加以隔離。
8、管道的沖洗是在管道試壓完畢后，可連續(xù)做沖洗工作。承包單位應(yīng)做好試壓和沖洗記錄。
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.
