Wet wet alarm valve system is composed, closed nozzle, flow meters, control valves, end water installations, pipelines and water supply facilities and other components. Filled with pressurized water pipe system, Shanghai fm certified fire sprinklers in case of fire, water nozzle immediately after the operation. Inside water distribution pipes full of quasi working condition for starting the system has a closed system pressure gases. Dry and wet systems similar to the structure and role of the principle only valve control signal is different between the water distribution network and water supply control signals to set the dry valve separates them, Chongqing fm certified fire sprinklers, and usually in the water distribution network in full the gas pressure for the system to start. In case of fire, gas spray nozzle first, Chengdu fm certified fire sprinklers, causing the pipe network pressure drop, fm certification fire sprinklers, water pressure in the pipeline to open water valve control signal into the distribution network, and then ejected from the nozzle extinguishing . However, this system requires several additional set of inflatable equipment, high one-time investment, usually manage more complex, slower fire. Chongqing fm certified fire sprinklers, creating Anyuan electromechanical, fm certification fire sprinklers by the Hubei Chong Anyuan Electrical Equipment Co., Ltd. to provide. Hubei Chong Anyuan Electrical Equipment Co., Ltd. (www.hbcay119.com) (www.hbcay119.com) is a leader in Wuhan, fire protection equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Anyuan electromechanical leadership in creating the staff warmly welcome all inquiries negotiations to create create a better future for electromechanical Anyuan.
