Problems solved by technology

However, increasing the water pressure is limited by the pump capacity and operating conditions, and it is not feasible in many cases; and the multi-nozzle fine water mist nozzle with multiple small holes is not only complicated in structure and high in cost, but also in the middle and low pressure single The atomization fineness of this fine water mist nozzle working in a fluid state is not ideal
In order to meet the primary fine atomization requirements of fine water mist nozzles under low pressure conditions, the nozzle diameter must be reduced, so the flow rate is small, the impulse is small, and the spray fire penetration is poor, which becomes the existing medium and low pressure single fluid fine water Common faults of mist nozzles

Embodiment 1

[0071] Embodiment 1: the open-type fine water mist nozzle of band double-annular crack nozzle and vortex device, swirler.

[0072] Referring to Figures 1 to 3, the inner cavity 1.0 of the nozzle seat 1 with the filter 5 is provided with a stepped cup-shaped nozzle body 2, the nozzle body inlet is equipped with a vortex seat 4, and the outer cylinder of the vortex seat seals the central cavity 2.0 of the nozzle body The tangential groove 2.10 on the entrance of the cavity wall, the outer thread of the nozzle is inserted and screwed into the inner cavity 1.0 of the nozzle holder. The vortex 3 with the vortex core 3.1 and the tangential groove 2.10 on the inlet of the nozzle body cavity constitute a two-stage series-parallel structure of the vortex and the cyclone of the nozzle body, and the outlet of the cyclone is connected to the center cavity 2.0 of the nozzle body. The central cavity of the large diameter end of the nozzle body shrinks into a cone hole (called the nozzle bod...

Embodiment 2

[0074] Embodiment 2: an open-type fine water mist nozzle with a double-annular slit nozzle and a two-stage cyclone.

[0075] See Figures 4-6. As shown in FIG. 4 , a stepped cup-shaped nozzle body 2 is arranged in the cavity of the nozzle seat with a filter. The entrance of the central cavity 2.0 of the nozzle body is provided with a primary cyclone 6, and the cap-shaped cyclone with a tangential groove 6.0 is set in the cyclone seat 7. The bottom of the cyclone seat is provided with a tangential groove 7.0 of the cyclone seat, and the top inclined surface of the tangential groove 7.0 of the cyclone seat coincides with the top cone surface 2.2 of the body cavity wall of the nozzle and is pressed against the top cone surface of the body cavity wall of the nozzle. The bottom of the device seat and the top cone of the nozzle body cavity wall together form a two-stage cyclone, and each inlet of the two-stage cyclone communicates with the inlet of the inner cavity of the nozzle sea...

Embodiment 3

[0076] Embodiment 3: the open-type fine water mist nozzle with double-annular slot nozzle, vortex device and spiral channel.

[0077] Referring to Figures 7 and 8, the structure shown in Figure 8 is basically the same as that of Embodiment 1, and the same parts will not be described again. The entrance of the body cavity of the nozzle is formed; the difference is that there is no tangential oblique hole on the wall of the body cavity of the nozzle in embodiment 3, but a spiral through groove 2.3; Shape, which is provided with a ring sheet 14 with a circle of reed whistle vibrator.

Abstract

The invention discloses a fine-water spraying head with double-ring crack sprayer, which comprises the following parts: sprayer seat, sprayer bulk and ring-shaped cavity between sprayer seat and sprayer bulk, wherein the ring-shaped cavity connects inlet of inner cavity of sprayer seat through channel, the little diameter part of sprayer bulk is set in the inner cavity of sprayer seat, the big diameter end of sprayer bulk is set out of inner cavity of sprayer head with big diameter end next to and baffle outlet of inner cavity of sprayer seat, the hollow double-ring crack is formed between big diameter end ring and inner cavity wall end of sprayer seat, the little diameter part of double-ring crack is inner-ring crack, which connects ring-shaped cavity, the big diameter part of double-ring crack is external ring crack, which lies between periphery of sprayer seat and big diameter end to connect atmosphere to form double-ring crack sprayer.

Description

technical field [0001] The present invention relates to a fine water mist nozzle with or without auxiliary devices suitable for producing special shapes or properties, such as jets, sprays or other discharges of individual droplets, and in particular to a spray head which is mainly used for fire fighting or other In the field of spraying, there is a fine water mist nozzle with a double-annular cracked nozzle capable of wide-angle dense fine spraying. technical background [0002] Water mist injection technology has a very wide range of applications. Take water mist fire extinguishing as an example. Water mist fire extinguishing is a green and environmentally friendly fire protection technology with a wide range of uses. The water mist nozzle is a key component of the water mist fire extinguishing system. The fine water mist nozzle can also be used in the field of spraying other low-viscosity fluids. The water mist sprayed by an ideal fine water mist nozzle should be fine, d...
