Inside water distribution pipes full of quasi working condition for starting the system has a closed system pressure gases. Dry and wet systems only control signal similar valve structure and function works differently, between the water distribution network and water supply control signals to set the dry valve to separate them, and in the distribution pipeline network usually filled with pressure gas for system start. In case of fire, gas spray nozzle first, causing the pipe network pressure drop, Chongqing fm certified fire sprinklers, water pressure in the pipeline to open water valve control signal into the distribution network, and then ejected from the nozzle fire. However, this system requires several additional set of inflatable equipment, high one-time investment, usually manage more complex, slower fire. According to different places you can choose different sprinklers: 1. pendent sprinklers pendent sprinkler is the most widely used one nozzle, drooping mounted on water supply branch pipe, fm certification fire sprinklers, sprinkler parabolic shape Guangdong Body, fm certification fire sprinklers, 80 to 100% of the total amount of water sprayed into the ground. Mainly used for decoration of places do not need, such as workshops, warehouses, parking garages, kitchens and other places. 2. Upright roof sprinklers suitable for installation in a moving object more impact prone places such as warehouses, but also concealed in a room in the mezzanine ceiling imposed to protect combustible ceiling more top boron. Upright sprinklers installed vertically on the water supply branch pipe, sprinkler type paraboloid shape, 80 to 100% of the total amount of water sprayed down, but there are still some sprayed ceiling.
