Automatic sprinkler system is one of the fixed fire extinguishing systems with the most extensive application and the highest fire extinguishing efficiency. The automatic sprinkler system is composed of sprinkler head, alarm valve group, water flow alarm device (water flow indicator or pressure switch), pipeline and water supply facilities, and can spray water in case of fire. It is composed of wet alarm valve group, closed sprinkler, water flow indicator, control valve, end water test device, pipeline and water supply facilities. The pipeline of the system is filled with pressurized water. In case of fire, spray water immediately after the sprinkler acts.
According to the sprinkler used, it is divided into two categories: closed sprinkler system; Open sprinkler system is adopted. In the automatic sprinkler system, the sprinkler is responsible for detecting fire, starting the system and spraying fire. It is the key component of the system. Sprinkler heads have many different forms of classification.
According to the sensitivity of sprinkler heads, sprinkler heads can be divided into fast response sprinkler heads, special response sprinkler heads and standard response sprinkler heads. Generally, the sensitivity of the sprinkler head is expressed by its response time index (RTI), which is the response time from receiving the fire alarm to the outlet of the sprinkler head.
According to this classification, the first type is fast response sprinkler head, and its response time index (RTI) is less than or equal to 50 (m * s)0.5; The second is the special response sprinkler head, whose response time index (RTI) is greater than 50 (m*s) 0.5and less than 80 (m * s)0.5; The third is the standard response sprinkler head, whose response time index (RTI) is greater than 80 (m * s)0.5 and less than 350 (m * s)0.5.
