Decorative plate and screw to apply soluble metal welding. Nozzle supporting block shot glass ball, block shot compress elastomeric seals, sealing the nozzle outlet. When fire occurs, the soluble metal decorative plate melting off. Sealed in the glass ball into the liquid as the temperature rises and inflation, at a predetermined temperature, the glass ball burst into pieces, the pressure of water flush through the block shot and elastomeric seals splash plate to the required shape and flow sprinklers. Installation Tips: Standard glass ball concealed type sprinkler heads installed in the pipe network layout spacing should be consistent with national standards.
