摘要

This standard applies to systems for protection of ducting, conveyors or chutes used in pneumatic materials handling systems and most often used in the woodworking and textile industries. Other installation types may also be applicable. Spark radiation detectors are mounted to view in the duct to sense ignition sources. These detectors send signals to a control device, which in turn actuates a valve for a predetermined extinguishing cycle. The valve supplies one or more water-spray nozzles mounted downstream of the detectors; the water discharge is timed to ensure suppression of the ignition source and the material shortly before and after the particle. Because such a system is intended only for protection from a specific hazard, it should not be considered a substitute for general fire protection, including appropriate sprinkler protection. 本标准适用于气动材料处理系统中使用的管道、输送机或斜槽的保护系统，最常用于木工和纺织行业。其他安装类型也可能适用。火花辐射探测器安装在管道中，用于探测点火源。这些探测器向控制装置发送信号，控制装置反过来驱动阀门进行预定的灭火循环。该阀门为安装在探测器下游的一个或多个喷水嘴供水；排水定时，以确保在颗粒前后不久抑制点火源和材料。由于此类系统仅用于防止特定危险，因此不应将其视为一般消防的替代品，包括适当的洒水保护。展开▼
