Working principle：

1. The concealed sprinkler is composed of glass bulb sprinkler, screw sleeve seat, outer cover seat and outer cover. The sprinkler and screw socket are installed on the pipeline of the pipe network together, and then the cover is installed. The outer cover base and the outer cover are welded into a whole by fusible alloy. After the installation, pressure test and purging of the spray pipe network are completed, install the fusible alloy sprinkler and screw socket on the spray short pipe (pay attention to control the length of the short pipe and keep the cover seat flush with the ceiling), and then install the cover.

2. The cover seat and cover of the concealed nozzle are welded into a whole by fusible alloy. When the melting point of the sprinkler is reached, the temperature of the alloy cover will automatically fall off as the temperature of the alloy cover increases.
