　　风管宽度超过1.2米时，应当在管道下方安装喷淋，采用下喷的形式，喷头应当设置在管道的下方，而不应与管道齐平或者设置在管道上方或侧方。喷淋头间距不能小于15公分，注意放水时不能打开通风。采用早期抑制快速响应喷头和特殊应用喷头的场所，当障碍物宽度大于0.6m时，其下方应增设喷头。

　　When the width of the air duct exceeds 1.2 meters, a sprinkler should be installed below the duct, using a downward spray form. The sprinkler should be placed below the duct, not flush with the duct or above or on the side of the duct. The distance between sprinkler heads should not be less than 15 centimeters, and attention should be paid to not opening ventilation when draining water. In places where early suppression rapid response nozzles and special application nozzles are used, nozzles should be added below obstacles with a width greater than 0.6m.

　　消防喷淋系统喷头安装基本要求

　　Basic requirements for installation of fire sprinkler system nozzles

　　1、直立型喷头安装距楼板顶部距离为规范要求为75mm-150mm。

　　1. The installation distance of the upright nozzle from the top of the floor slab is required by the specifications to be 75mm-150mm.

　　2、有吊顶的下垂型喷头安装喷头根部应与吊顶平齐，为避免定位不准，可在吊顶龙骨标高确定后再安装下喷支管；下喷头与三通之间的短管长度不宜超过150mm。

　　2. The installation of hanging nozzles with suspended ceilings should be flush with the base of the nozzle. To avoid inaccurate positioning, the lower spray pipe can be installed after the elevation of the ceiling keel is determined; The length of the short pipe between the nozzle and the tee should not exceed 150mm.

　　3、边墙型喷头安装离墙距离为50-100mm。

　　3. The installation distance of the side wall type nozzle from the wall is 50-100mm.

　　4、无吊顶时设置上喷头；有吊顶时设置下喷头，当吊顶上方闷顶的净空高度超过800mm，且其内部有可燃物时，要求设置上喷头；喷头在系统冲洗试压合格后安装；当喷淋支管高度大于1000mm时，应设横向加强支架；当不确定装修方案是否有吊顶时可预留三通口，丝堵封堵。

　　4. Install upper nozzles when there is no ceiling; When there is a suspended ceiling, a lower nozzle should be installed. When the clearance height above the suspended ceiling exceeds 800mm and there are combustibles inside, an upper nozzle should be installed; The nozzle shall be installed after the system flushing and pressure test is qualified; When the height of the spray branch pipe is greater than 1000mm, a transverse reinforcement bracket should be installed; When it is uncertain whether the decoration plan has a suspended ceiling, a three-way port can be reserved and sealed with a screw plug.

　　5、喷淋管道末端应采用梯形防晃支架；末端支架与喷头之间的距离为400mm

　　5. The end of the sprinkler pipe should be equipped with a trapezoidal anti sway bracket; The distance between the end bracket and the nozzle is 400mm

　　6、当梁、通风管道、排管、桥架宽度大于1.2m时，增设的喷头应安装在其腹面以下部位；风管下喷头吊架应采取管道延长风管另外一端边缘，并在延伸管道末端设置吊架。

　　6. When the width of beams, ventilation ducts, ducts, and cable trays is greater than 1.2m, additional nozzles should be installed below their belly surface; The nozzle hanger under the air duct should be extended to the edge of the other end of the air duct, and a hanger should be installed at the end of the extended pipe.

　　7、喷淋管道安装应主管在下；喷淋管支管在主管上方，朝主管方向形成坡度，便于系统维护泄水。

　　7. The installation of sprinkler pipes should be supervised by the supervisor; The spray pipe branch is located above the main pipe, forming a slope towards the main pipe direction for easy maintenance and drainage of the system.
