Product Description
Product Overview
The ZSTDY concealed sprinkler head is available in two types: quick response (3mm glass ball) and normal response (5mm glass ball). The sprinkler head is built into the shroud, giving it a certain decorative effect. It is the best choice for places where the appearance of the decoration is important, such as hotel lobbies, office buildings, and airports. It is used in automatic sprinkler fire suppression systems and the height of the outer cover can be adjusted according to the height of the ceiling.
The concealed sprinkler head consists of a sprinkler head, shroud, outer cover seat, and outer cover. The sprinkler head and shroud are installed on the pipeline together, and then the outer cover is installed. The outer cover seat and outer cover are welded together by fusible alloy. When a fire occurs, the ambient temperature rises, and when it reaches the melting point of the fusible alloy, the outer cover automatically falls off. As the temperature continues to rise, the glass ball in the shroud breaks due to the expansion of the temperature-sensitive liquid, thereby activating the sprinkler head and automatically spraying water.
