QRS Electronic Accelerator has the following characteristics: * dry pipe valves in four seconds or less action - depending on different combinations of pressure pipe network, pipe network volume, Shenyang FM authentication signal butterfly doors, nozzle flow coefficient K values. * Built-in low pressure and high pressure alarm monitoring devices. * When tape backup battery, in order to ensure reliable operation of mains failure Venturi tube flowmeter flow meter and for testing fire pump performance. When the flowmeter to the pipe, before and after the meter has a minimum length of straight pipe access requirements, Chengdu FM authentication signal butterfly doors, see below. Meter maximum range = 2 × required to measure the maximum range value Note: This product brand GERAND. Hubei Chong Mechanical and Electrical Equipment Co., Ltd. Anyuan virtue of the NFPA codes and standards of a deep understanding of FM, adhering to customer service for the origin and the pursuit of continuous innovation and improvement of its own after years of rapid development has become FM / UL certification of fire products most active, FM authentication signal butterfly doors, the most effective supply of services. Wet or dry start to start the system by the nozzle boot system, FM authentication signal butterfly doors, provide fire alarm signal flow alarm pressure switch action after pre-action system, so no need to design electrical fire detection system. Under normal circumstances, the detection elements of the system designer to select a single chain of pre-action fire system response speed faster than the automatic fire sprinklers. Inflation pressure pipe network only 0.69bar, so the system filling water into a wet pipe system, only experience a short delay before the action in fire sprinkler system has been filled with water to a wet system. Shandong FM authentication signal butterfly doors, creating Anyuan electromechanical, FM certification signal valve gate 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.
