Abstract

The invention discloses a jet-driven rotary spraying head, which comprises a hollow base and a spraying head body capable of rotating relative to the base, wherein a fluid passage is arranged inside the spraying head body, and spraying orifices are formed outside the spraying head body; each spraying orifice at least comprises two eccentric spraying orifices capable of generating eccentric spraying flows; the spraying flows of the eccentric spraying orifices rotate the spraying head body; and the setting direction of each eccentric spraying orifice should make the spraying head body rotate in the same direction. A rotary matching surface is arranged between the spraying head body and the base; the spraying head body drives the spraying orifices formed thereon to rotate together, a fluid permeating the rotary matching surface is used for lubricating the rotary matching surface; at least one matching surface gap, capable of leaking the fluid outwards, in the rotary matching surface is designed into a circular seam spraying orifice; and a small amount of the fluid joins in the spraying of the spraying head through the circular seam spraying orifice. The spraying head uses spraying jet flow reacting force of the eccentric spraying orifices to cause autorotation, and can also solve the problems of large-area uniform spraying and fine atomization while working at meddle and low pressures.

Description

technical field [0001] The invention relates to a spraying device, in particular to a jet-propelled rotary spray head, which is mainly used in the field of fire-fighting and extinguishing, and can also be used as an environmental protection spray. Background technique [0002] The rotary power of some rotary sprinklers is driven by motors, but the motor drive system is complex in structure, large in size and needs to provide additional rotary power. Some rotary sprinklers driven by fluids (such as rotary sprinklers) do not have spray functions and structures suitable for fire extinguishing. The traditional water mist nozzle or fine water mist nozzle in the field of fire protection is a fixed nozzle. Due to structural limitations, it sprays unevenly, and there is a spray dead angle in the protected area. The solution is rotary spraying, which requires the use of rotary sprinklers. The Chinese utility model patent with application number 200520091525.7 discloses a large-flow ...
