Automatic spray system

The utility model discloses an automatic spray system. The automatic spray system comprises a spray device, wherein the spray device comprises a first cavity and a second cavity which are communicated with each other, the second cavity is connected with a second branch pipe provided with a switching valve, the lower side of the first cavity is connected with a temperature sensing control, the temperature sensing control comprises a temperature sensing pipe propped against the lower end surface of a closed plunger, the second cavity is provided with a water outlet pipe, and a first nozzle is rotationally connected onto the water outlet pipe; when the temperature of a room exceeds a preset valve of the temperature sensing control, water flows enter the second cavity from the first cavity; when the temperature sensing control breaks down, the switching valve can be opened, and the water flows enter the second cavity, so that the system is better in safety and flexibility; the first nozzle is rotationally connected onto the water outlet pipe, so that the first nozzle can rotate at the high speed around the water outlet pipe under the action of the power produced by the water flows, water is sprayed by the nozzle, the protection radius is large, and the fire extinguishment efficiency is high. The automatic spray system is better in safety and flexibility and high in fire extinguishment efficiency.
