Abstract
The utility model discloses a temperature-sensing rotary type sprinkling fire extinguishing spray head which comprises a water inlet pipe, a rotation component rotating with respect to the water inlet pipe and a water distribution cavity which is fixedly connected with the rotation component and provided with a plurality of water spraying holes for water spraying and ventilation. A water stopping valve is arranged in the water distribution cavity, a plurality of allotypic flaky wings which correspond to the water spraying holes are mainly arranged on the lower edge of the water stopping valve, and shapes of the water spraying holes correspond to axial projection shapes of the allotypic flaky wings. When fire alarm is generated, a temperature-sensing glass ball is broken, because of the gravity or hydraulic power action, the water stopping valve loses support to be flushed by water pressure and slides along the corresponding water spraying holes depending on the allotypic flaky wings on the lower edge all the time until completely opening, and water is sprayed from the water spraying holes. Meanwhile, the reaction force of hydraulic power acts on the water stopping valve, and a fire extinguishing spray head automatically rotates with 360 DEG to generate a centrifugal force to throw out the water. The fire extinguishing spray head has the advantages of favorable water pressure seal, large working strength, raw material conservation, big spraying fire extinguishing area, uniform spraying and density water drip.
