Standard Response Concealed Sprinkler

    SANJING concealed sprinkler head is installed on the pipeline fittings together with the glass ball nozzle and the outer shell, and then the inner sleeve is installed. The inner sleeve and bottom plate are welded together by fusible alloy. In the event of a fire, the ambient temperature rises and reaches the melting point of the fusible alloy. The bottom plate automatically falls off and the splash plate moves downwards. As the temperature continues to rise, the glass ball of the nozzle inside the shell breaks and sprays water due to the expansion of temperature sensitive liquids, implementing firefighting operations.
