Standard glass ball sprinkler head, sprinkler system is composed of the basic components, used in shopping malls, hotels, hotel lobby decorated beautiful place and other requirements. It can sense a fire detection and fire sprinkler can. The company produces a variety of standard glass ball sprinkler head, products based on GB5135.1-2003 "Automatic sprinkler systems Part 1: sprinkler head" standard, the framework of the forging material is cast brass, chrome plated and processed into. Nozzle used in the production of glass balls and elastomeric seals Kubo companies to import from Germany. All the glass ball sprinkler head are detected by the state from inspection. Structure and working principle of: Sprinklers installed in the adjustable screw put on, to adjust the ceiling decorative ceiling plate and the distance between. 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. Installation of the company's standard glass ball concealed type sprinkler heads must use the company's special wrench. Wrench tighten the sprinkler frame against the support arm, which can cause frame distortion caused by sprinkler leakage. Glass ball can not hit more bumps, resulting in errors after the spray nozzles or fire, the nozzle can not open the sprinkler and other serious consequences. Only in the length of the screw sets for the reorientation around 10mm, pay attention to the length of the short riser is not too much error. Transport and storage: Transportation process should be rain, sun, anti-impact shock absorption. Should be stored at -15 °C -40 °C in the dry environment.
