Automatic sprinkler system, it simply is in case of fire, can automatically start the sprinkler sprinklers to protect the personal and property safety of a controlled fire extinguishing system. Sprinkler systems development so far, more than 100 years of history, the first is "drill pipe sprinkler system" forms, gradually developed into a modern sprinkler system. As technology advances, the current fire sprinkler system's response to the increasingly rapid, and reliability have been greatly improved. Especially on nozzle research and development, so that the fire extinguishing system used more widely. Since the 20th century, since the early 60s, automatic sprinkler head, being able to adapt to the needs of the fire danger situation a rapid development. Mainly used in three areas: first, elevated high in the protection of the heap storage area. Because of high overhead storage in the heap needs more jet penetration to the implementation of fire, then produced a large drop sprinklers. Large drop out of the nozzle flow, droplet size large, the flame can penetrate thick, reaching the fire source center, rapidly cooling to fire extinguishing purposes; the second is to protect the personal safety, such as kindergartens, hospitals, nursing homes and other places , number of children protected objects are young and old or sick persons with mobility problems. Therefore, in these occasions need to react quickly, move faster nozzle in order to control the fire in the early stages of a fire, then had a quick response sprinklers; third building renovation to meet the aesthetic requirements, such as in shopping malls, hotels , restaurants and other places of a beautiful small applications of glass ball heads. Development in the nozzle 100 years, before and after the introduction of hundreds of nozzle, the nozzle has been improved rapidly introduce new sprinkler system's performance, so that automatic sprinkler system, fire control, fire rate and system reliability is improved. Automatic sprinkler system from the initial drilling sprinkler system to the modern sprinkler systems, the system continuously improving range of applications have been expanded. First wet sprinkler system are based on the system, that is, filling a long pipe to the pressure of water, fire, water sprinklers can rapidly after opening fire. Wet sprinkler system because the system is simple, fire control fire rate, is still the most widely used an automatic sprinkler system, but it applies only to the ambient temperature at 4 ? 7 occasions, the cold region not heating the building can not use the system, initially in order to solve this?? issue to the pipe filling with antifreeze, to 1885, Grinnell invented the bellows differential dry valve, only the dry -type sprinkler system. In recent coming year, with the fire detection technology and electronic technology, people began to study fire detection technology with automatic sprinkler system combined to maximize the sprinkler system reliability and fire safety efficiency, there was a pre-function sprinkler system, rain and fire fighting systems, etc.. With the development of social and economic development of the fire, the fire control security needs to improve, with the increase of fire hazards, fire sprinkler technology will be faced with increasing challenges, and science and technology was to provide newer and good performance, more secure and reliable automatic sprinkler system may create the conditions. Sprinkler system used in China for over 50 years. Before and after 30 years of this century, some foreign companies operate in China textile mill factory and a number of senior civil construction to start the installation using the automatic fire extinguishing system. 50's reconstruction in the Soviet Union a number of textile mills and our own design? Some of the factory, are equipped with automatic sprinkler system. Since 1949, China has produced a few plants had 72 , 141t fusible sprinklers and control valves and other products. Later, made the automatic sprinkler system in our country has been more widely used, such as table tennis in 1956, established the Shanghai plant, in October 1978 as the workshop include silk thread will be up to celluloid wrapped fire, from the sprinkler system automatically starts the fire out. Another example is the 1958-built textile factory in Xiamen, automatic sprinkler system installed after the fire four times, to open automatically extinguished by the sprinklers.
