The agricultural rotary water spray nozzle can spray water obliquely and can rotate automatically, is wide in spraying range, large in spraying area and even in wetting, and is a best drought resisting device.

Pressure storage type compressed gas foam extinguishing system

The invention discloses a pressure storage type compressed gas foam extinguishing system which comprises a pressure liquid storage tank and a foam generator. The pressure liquid storage tank is filled with foam extinguishing agent mixed liquid and compressed gas. The foam generator is arranged in the pressure liquid storage tank and the foam generator is located above the foam extinguishing agent mixed liquid. A gas inflow hole, a liquid inlet and a turbulator are arranged on the foam generator. The liquid inlet is communicated with a liquid suction pipe arranged at the lower end of the foam generator. The bottom of the liquid suction pipe is located on the lower portion of the pressure liquid storage tank. A foam outlet pipe connected with the foam generator is arranged at the top end of the pressure liquid storage tank. A foam delivery pipe is arranged on one side of the pressure liquid storage tank and communicated with the foam outlet pipe. A foam gun is arranged at the tail end of the foam delivery pipe. The pressure storage type compressed gas foam extinguishing system can generate even, exquisite and stable kinetic energy foam without sucking air from the outside and is high in extinguishing speed, wide in covering range and large in jet distance.
