洒水喷头分为哪几种？

What are the types of sprinkler heads?

洒水喷头分为闭式和开式两种。闭式玻璃球洒水喷头是湿式自动喷水灭火系统重要的部件，能起到探火和灭火的双重功能。按灭火功能或保护区域划分，洒水喷头可分为普通洒水喷头、干式喷头、家用喷头、扩大覆盖面积洒水喷头、早期抑制快速响应喷头、特殊应用喷头、雨淋喷头、水雾喷头、水幕喷头等。

Sprinkler heads are divided into closed type and open type. Closed glass ball sprinkler head is an important component of wet automatic sprinkler system, which can play the dual functions of fire detection and fire extinguishing. According to the fire-fighting function or protection area, sprinkler heads can be divided into ordinary sprinkler heads, dry sprinkler heads, household sprinkler heads, sprinkler heads with expanded coverage area, early suppression rapid response sprinkler heads, special application sprinkler heads, rain sprinkler heads, water mist sprinkler heads, water curtain sprinkler heads, etc.

Closed glass ball sprinkler head is an important component of wet automatic sprinkler system, which can play the dual functions of fire detection and fire extinguishing.

喷头应布置在顶板或吊顶下易于接触到火灾热气流并有利于均匀布水的位置。当喷头附近有障碍物时，应符合本规范的规定或增设补偿喷水强度的喷头。

The sprinkler shall be arranged under the top plate or ceiling where it is easy to contact the fire hot air flow and is conducive to uniform water distribution. When there are obstacles near the sprinkler, it shall comply with the provisions of this specification or add a sprinkler to compensate the sprinkler intensity.

直立型、下垂型喷头的布置，包括同一根配水支管上喷头的间距及相邻配水支管的间距，应根据系统的喷水强度、喷头的流量系数和工作压力确定，并不应大于表7.1.2的规定，且不宜小于2.4m。

The arrangement of vertical and drooping nozzles, including the spacing between nozzles on the same water distribution branch pipe and the spacing between adjacent water distribution branch pipes, shall be determined according to the sprinkler intensity of the system, the flow coefficient of the nozzle and the working pressure, and shall not be greater than the provisions in table 7.1.2, and shall not be less than 2.4m.

除吊顶型喷头及吊顶下安装的喷头外，直立型、下垂型标准喷头，其溅水盘与顶板的距离，不应小于75mm，不应大于150mm。

Except for the ceiling sprinkler and the sprinkler installed under the ceiling, the distance between the splash tray and the top plate of the vertical and drooping standard sprinkler shall not be less than 75mm and not more than 150mm.

自动喷淋灭火系统的组成部件由水池+阀门+水泵+气压罐控制箱+主干管道(+屋顶水箱)+分支次干管道+信号蝶阀+水流指示器+分支管+喷淋头+排气阀+末端排水装置组成。消防喷淋系统的设计原则是根据使用场所的面积以及需要消防的对象而决定喷淋头的数量和种类的。

The components of the automatic sprinkler system are composed of pool + valve + water pump + air tank control box + main pipeline (+ roof water tank) + branch secondary main pipeline + signal butterfly valve + water flow indicator + branch pipeline + sprinkler head + exhaust valve + end drainage device. The design principle of fire sprinkler system is to determine the number and type of sprinkler heads according to the area of the place of use and the objects that need fire protection.

洒水喷头应选用多少温度等级？

What temperature class should the sprinkler be selected?

川消小编提示，该处喷头少应选用93°C甚更高温度等级的喷头。洒水喷头的施工安装环节非常关键，如果由未经培训的人员进行施工安装，会给消防工程留下质量隐患。尤其是层层分包的消防工程项目，施工现场难免有未经培训和考核的施工人员，他们对洒水喷头的结构原理、性能和操作维护等缺乏了解，施工安装时随意、马虎。

According to the tips of Chuanxiao Xiaobian, the sprinkler at this place should be at least 93 ° C or higher. The construction and installation of sprinkler heads is very critical. If the construction and installation are carried out by personnel without professional training, it will leave quality hidden dangers to the fire engineering. In particular, for the fire engineering projects subcontracted layer by layer, it is inevitable that there are untrained and assessed construction personnel on the construction site, who lack understanding of the structural principle, performance, operation and maintenance of sprinkler heads, and are careless in construction and installation.

洒水喷头的保护面积用量是多少？

What is the amount of sprinkler protection area?

扩大覆盖面积洒水喷头的保护面积用量大可达36m2，能大大减少保护面积内的喷头数量和管道用量，降低工程造价。适用于建筑内轻、中危险场所，尤其是较大面积的宾馆客房。

Expanding the coverage area, the amount of sprinkler protection area can reach 36m2, which can greatly reduce the number of sprinkler heads and pipe consumption within the protection area and reduce the project cost. It is suitable for light, medium and dangerous places in buildings, especially hotel rooms with large areas.
