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 panel of the concealed sprinkler head is used to decorate and shield the sprinkler head. When the fire happens, the temperature rises, the decorative panel falls off by itself because of the temperature rise, and then the temperature continues to rise, and the sprinkler head bursts and starts spraying water
1. The special wrench provided by the manufacturer must be used, and other tools shall not be used for installation;
2. Before installation, when separating the sprinkler head (outer cover and outer cover seat), it should be gently screwed down and properly put in
In the foam box, do not use brute force to forcibly separate, otherwise it is easy to cause the outer cover and the outer cover seat fall off;
3. During installation, wrap enough raw material belt around the thread of the sprinkler head and gently screw the sprinkler head into the thread of the pipe fitting, and then screw the sprinkler head on with a special wrench. The gap between the sprinkler base and the pipe fitting should be kept at 2-3MM.
4. The fusible alloy sheet of the sprinkler head and the frame of the sprinkler head are fragile. When installing the sprinkler head, the wrench must not collide with the fusible alloy sheet and the meet frame, otherwise it is easy to cause the sprinkler head to spray by mistake;
5. The concealed sprinkler head cannot be installed repeatedly. Once installed, it cannot be used again.
Concealed sprinkler head compared with conventional sprinkler head has higher aesthetic, but the most taboo of concealed sprinkler head is that the lid is stained with paint and paint, so it will cause action failure.
