川消喷头的选择

Selection of Chuanxiao nozzle

1、对于喷头的喷孔易被外部异物堵塞的场所，应选用具有相应防护措施且不影响细水雾喷放效果的喷头，如粉尘场所应选用带防尘罩（端盖）的喷头，但在喷雾时不应阻挡水雾和对人员造成的伤害；

1. For places where the nozzle hole is easy to be blocked by external foreign matters, the nozzle with corresponding protective measures that will not affect the spray effect of water mist shall be selected. For dust places, the nozzle with dust cover (end cover) shall be selected, but the water mist and personal injury shall not be blocked during spray;

2、对于电子数据处理机房、通信机房的地板夹层，宜选择适用于低矮空间的喷头；

2. For the floor mezzanine of electronic data processing room and communication room, the nozzle suitable for low space should be selected;

3、对于闭式系统，应选择响应时间指数不大于50(m·s）0.5的喷头，其公称动作温度宜高于环境温度高温度30℃，且同一防护区内应采用相同热敏性能的喷头；

3. For the closed system, the nozzle with response time index no more than 50 (m · s) 0.5 shall be selected, its nominal operating temperature should be 30 ℃ higher than the ambient temperature, and the nozzle with the same thermal sensitivity should be used in the same protection zone;

4、对于腐蚀性环境，应选用采用防腐材料或具有防腐镀层的喷头；

4. For corrosive environment, the nozzle with anti-corrosion materials or anti-corrosion coating shall be selected;

5、对于电气火灾危险场所的细水雾灭火系统，不宜选用撞击雾化型细水雾喷头。

5. For the water mist fire extinguishing system in the electrical fire hazard area, the impact atomization water mist nozzle should not be selected.

川消喷头的布置要求

Layout requirements of Chuanxiao sprinkler

闭式系统的喷头布置应能保证细水雾喷放均匀并完全覆盖保护区域；喷头与墙壁的距离不应大于喷头大布置间距的1/2；喷头与其他遮挡物的距离应保证遮挡物不影响喷头正常喷放细水雾，当无法避免时，应采取补偿措施；喷头的感温组件与顶棚或梁底的距离不宜小于75mm，且不宜大于150mm。当场所内设置吊顶时，喷头可贴邻吊顶布置。

The sprinkler arrangement of the closed system shall ensure that the fine water mist is sprayed evenly and completely covers the protection area; The distance between the nozzle and the wall shall not be greater than 1/2 of the large spacing of the nozzle; The distance between the nozzle and other obstructions shall ensure that the obstructions do not affect the normal spray of fine water mist by the nozzle. When it is unavoidable, compensation measures shall be taken; The distance between the temperature sensing component of the nozzle and the ceiling or beam bottom should not be less than 75mm, and should not be more than 150mm. When the ceiling is set in the site, the sprinkler can be arranged close to the ceiling.

开式系统的喷头布置与闭式系统的喷头布置要求相同，但对于电缆隧道或夹层，喷头宜布置在电缆隧道或夹层的上部，并应能使细水雾完全覆盖整个电缆或电缆桥架。

The sprinkler arrangement of the open system is the same as that of the closed system, but for the cable tunnel or interlayer, the sprinkler should be arranged at the upper part of the cable tunnel or interlayer, and should be able to completely cover the entire cable or cable bridge with fine water mist.

喷头布置应能保证细水雾完全包容或覆盖保护对象或部位，喷头与保护对象的距离不宜小于0.5m。用于保护室内油浸变压器时，变压器高度超过4m的，喷头宜分层布置；冷却器距变压器本体超过0.7m的，应在其间隙内增设喷头；喷头不宜直接对准高压进线套管；变压器下方设置集油坑的，喷头布置应能使细水雾完全覆盖集油坑。

The nozzle arrangement shall ensure that the water mist completely covers or covers the protected object or part, and the distance between the nozzle and the protected object shall not be less than 0.5m. When it is used to protect indoor oil-immersed transformer, if the transformer height exceeds 4m, the nozzle should be arranged in layers; If the distance between the cooler and the transformer body is more than 0.7m, the nozzle shall be added in its gap; The nozzle should not be directly aligned with the high-voltage incoming bushing; If an oil sump is set under the transformer, the nozzle arrangement shall be able to completely cover the oil sump with fine water mist.

系统应按喷头的型号、规格储存备用喷头，其数量不应小于相同型号、规格喷头实际设计使用总数的1%，且分别不小于5只。更多相关内容就来我们网站http://www.cx-fire.com咨询！

The system shall store spare sprinklers according to the model and specification of sprinklers. The number of spare sprinklers shall not be less than 1% of the total number of actual designed sprinklers of the same model and specification, and shall not be less than 5.
