RC-1 RC-1 type delay-Delay is installed in the water pressure fluctuations (such as a public water supply system) wet system, prevent the water system pressure fluctuations caused false alarms. When the nozzle moves, stable continuous flow of water into the sprinkler system pipe network, wet alarm valve plate open, the water flows from the throttle valve alarm port inlet orifice assembly (pore size 5.6mm), part of the water from the outlet section of the throttle assembly orifice (aperture 3.2mm) outflow valve Shanghai fm certification, the rest of the water injection to delay chamber. After the delay cavity filled, out of the water so that the water alarm and / or water pressure alarm switch action, as long as the valve plate open, the alarm on ongoing, fm certification valve until the valve plate is closed. RC-1 type delay fluctuations in water pressure in the water supply system, an instant rise in water pressure valve plate to open, there is water flowing from the alarm port, Chongqing fm certification valve, the delay due to the buffer chamber body, not Police immediately. When the momentary fluctuations in pressure drop, Shandong fm certification valve, the valve plate closed, delayed water chamber through the throttle body assembly outlet orifice emissions. Anyuan Hubei Chong Mechanical and Electrical Equipment Co., Ltd. The company provides FM spray product certification, FM certification sprinklers, FM certification deluge valve FM certification / UL registered sprinkler system products Tyco central spray Po (TycoFire & amp; Building Products) series spray leaching system products, including various types of sprinklers, wet alarm valves, deluge valves, flow indicator ACC-1 dry-type valve quick opening device, the external reset ACC-1 dry-type valve quick opening device (hereinafter referred to as accelerator) with the DPV-1 Dry Type Valve (2-1 / 2 "3" 4 "6"), supporting devices. ACC-1 Accelerator dry-type valve can be shortened from the nozzle (or only one) action to dry valve operation time. fm Certification valves | Year Anyuan electromechanical valves fm certification | fm certified valve by the Hubei Chong Anyuan Electrical Equipment Co., Ltd. to provide. fm Certification valves | Year Anyuan electromechanical valves fm certification | fm certification valve Anyuan Hubei Chong Mechanical and Electrical Equipment Co., Ltd. (www.hbcay119.com) (www.hbcay119.com) this year introduced a new upgrade, the above picture is for reference Please call the telephone or pictures on this page, for the latest information, contact: Liu law.
