The automatic sprinkler fire extinguishing system of fire equipment belongs to a fixed fire extinguishing system, which consists of sprinkler heads, alarm valve groups, and water flow alarm devices（pressure switch）Composed of pipeline systems, water supply facilities, etc., it is currently a widely used fixed fire-fighting facility in the world. It has the characteristics of low price and high fire extinguishing efficiency. It can automatically spray water to extinguish a fire and issue an alarm while extinguishing the fire. In some developed countries' fire safety regulations, almost all buildings are required to use automatic sprinkler systems. There can be many different system forms depending on the nature of the protected building and the characteristics of fire occurrence and development. Usually, according to the different forms of nozzles used in the system, it is divided into two categories: closed automatic sprinkler fire extinguishing systems and open automatic sprinkler fire extinguishing systems. In China, with the rapid development of the construction industry and the gradual improvement of fire safety regulations, automatic sprinkler systems have also been widely used.

The automatic sprinkler fire extinguishing system is in standby mode for a long time. When a fire occurs in a protected area, the ambient temperature rises, and the temperature sensitive element of the sprinkler head ruptures. The sprinkler head automatically sprays water directly into the fire area. The water flow from the fire water tank passes through the alarm valve, which outputs an alarm water flow hydraulic alarm bellUE pressure switchIt is used for the hydraulic alarm bell alarm system. This system is an important component of the automatic sprinkler fire extinguishing system. When a fire occurs, water with a certain pressure flows out from the alarm valve to drive the hydraulic alarm bell to sound an alarm. When the flow rate of the alarm bell is equal to or greater than the flow rate of one nozzle, it will immediately activate.

andElectronic pressure switchDifferent,Mechanical pressure switchWithout the need for power supply, it has higher reliability and is therefore more widely used in firefighting equipment. Depending on the specific project, the fire protection system of a general building can be equipped with a universal pressure switch, but in hazardous environments such as chemical, petroleum and petrochemical, and offshore platforms, it is necessary to equip it with a universal pressure switchExplosion proof pressure switchEven explosion-proof pressure switches. Beijing Kangnansen Instrument Technology Co., Ltd. can provide comprehensive instrument matching solutions for fire engineering companies. In addition to the pressure switches mentioned above, the water tanks used for long-term storage can be equipped with ultrasonic level gauges, and the pipeline system can be equipped with flow switches to provide dual protection. These should have been very mature abroad, and many domestic highway fire protection systems are typical cases of successful application of our products.
