Body 8 is connected, and the one end of start and stop lever 6 is arranged on the start and stop lever of water swivel in guide hole b, with the sealing ring 4 on start and stop lever 6
Sealed, the other end is arranged under the start and stop lever of head body 8 in guide hole g；Glass rod 11 is arranged on the glass of the lower end of start and stop lever 4
On glass bar between supporting 10 and the glass rod lower support 12 of the melon end of head body 8 three, and by installed in entering the inner face of water swivel 1
With the pre-pressing of spring 7 between the crossette anchor ring of closed rod 4.
Specifically, two layers of spray holes is provided with the downside in the outer spherical face of head body 8, outer layer spray orifice shares 4,
The spray orifice is made up of two adjacent logical direct current hole h and cylinder guide hole i；Internal layer spray orifice shares 7, and the spray orifice is adjacent logical by two
Direct current hole e and circular cone guide hole f composition.The internal layer spray orifice is distributed on the first parallel A1 of the spherical spraying area, described
Outer layer spray orifice is distributed on the second parallel A2 of the spherical spraying area relative to the internal layer spray orifice, the second parallel A2's
Girth is more than the girth of the first parallel A1.
Further, the shower nozzle cavity 8 includes the sleeve connection section 80 that extends laterally, the sleeve connection section 80 it is interior
Portion has excessively stream chamber c, and the inside of the shower nozzle cavity has shunting chamber d, the internal layer spray orifice and the outer layer spray orifice
Direct current hole connected respectively with the shunting chamber d.The entrance adapter 1 is connected to the sleeve connection section by external screw thread
80, sealing ring 3 is provided between the entrance adapter 1 and the sleeve connection section 80.One side end of the spherical spraying area
Protection cap 13 is installed, start and stop lever 6 is actively located in the protection cap 13.
Fig. 2 is scrutinized, more preferably, outer layer spray orifice is dispersed in outside two-by-two, adjacent relative to the axis of head body 8
Two outer layer spray orifices between angle theta 2 be 25 ° to 35 °, internal layer spray orifice and the interlaced arrangement of outer layer spray orifice, relative to spray
The axis of head body 8, the angle theta 1 between adjacent internal layer spray orifice and outer layer spray orifice are 10 ° to 20 °.
Fig. 3 is scrutinized, more preferably, between the axis of the outer layer spray orifice of shower nozzle (i h) and the axis of whole shower nozzle
Slanted angle α is 50 ° to 70 °, and cylinder pod apertures i depth a be 4mm to 8mm, cylinder pod apertures i aperture D be 4mm extremely
6mm, the slanted angle β between the axis of internal layer spray orifice (e f) of shower nozzle and the axis of whole shower nozzle are 25 ° to 35 °, circular cone
Shape pod apertures f taper degree γ is 50 ° to 70 °, and conical pod apertures f depth b is 3mm to 6mm, internal layer direct current spray orifice e's
ApertureFor 0.4mm to 0.8mm.
So accurate angle and aperture are set, and make shower nozzle sprinkling farther evenly, and then the water smoke distribution sprayed is in
It is rectangular-shaped, to significantly improve extinguishing effect.
During in-site installation, whole shower nozzle is horizontally arranged in side wall (wall), is provided with half of spherical court of multiple spray orifices
Under, enter the screw thread 2 of water swivel 1 and be connected with the kink nut on external range pipe, by compressing the inner cone on water swivel 1
Face is sealed with the male cone (strobilus masculinus) on water distribution pipe joint or sphere.In quasi-operating status, fire protection pipeline voltage stabilizing water flows into shower nozzle
On water inlet a and start and stop lever in guide hole b, due to there is sealing ring 4 on start and stop lever to be sealed, press water can not enter inside shower nozzle
Excessively stream chamber c and branch chamber d, shower nozzle are not sprayed water.
As shown in figure 4, when a fire, glass rod 11 ruptures in the presence of fire scene temperature, start and stop lever 6 connects with water
Moved in the presence of the hydraulic pressure and the bounce of spring 7 of contacting surface to the broken direction of glass rod 11, remove one end of start and stop lever and open
Close bar pod apertures b, while that lower seal 9 is pressed on into guide hole surface under start and stop lever is close by guide hole for crossette ring surface on start and stop lever
Close.Then, press water flows into excessively stream chamber c and branch chamber d inside shower nozzle by guide hole on start and stop lever, through internal layer direct current hole e, circular cone
Apopore f water smoke sprays to external diffusion, meanwhile, the water smoke through outer layer direct current hole h, cylinder apopore i sprays along straight line.
Embodiment two：
On the basis of embodiment one, the present embodiment does further change to whole shower nozzle.As shown in figure 5, this practicality is new
Type additionally provides a kind of relatively simple lateral spray type open type fine mist spray head of structure, on the downside outer spherical face of head body 8
Two layers of spray holes is provided with, the distribution in hole and pore structure are provided with a structure and internal layer at the center of shower nozzle sphere as enclosed
Spray in hole identical hole.Shower nozzle is horizontally arranged in side wall (wall), opens porose spherical face-down, the connection of shower nozzle and range pipe
Mode is as automatic sprinkler.Maximum difference is with embodiment one, and whole shower nozzle is structure as a whole and eliminates start and stop lever
And the on-off structure design of glass rod.
And it is blank pipe that set zone valve, which exports to pipe-line, in quasi-operating status, in fire-fighting place, shower nozzle is not
Water spray.When a fire, the zone valve in region on fire is opened, and press water flows into shower nozzle by pipeline from region valve outlet and enters water
Mouth a and water branch chamber d, through internal layer and shower nozzle top center direct current hole e, circular cone pod apertures f and outer layer direct current hole h, cylinder water conservancy diversion
Hole i sprays simultaneously.
Under application state, because high pressure (generally higher than equal to 8MPa) water (is generally less than equal to by minor diameter
Enter atmospheric pressure after 0.8mm) being spurted behind direct current hole, the pressure atomization effect with strength in the presence of larger pressure difference, through circle
It is in the coniform injection of low-angle after post, the atomization of circular cone pod apertures, due to the spray orifice of certain rule being distributed with the sphere of downside, often
Individual spray orifice is spurted the refinement droplet of low-angle Far Range by different angles, and the water mists that whole shower nozzle is spurted just have range
Far, the characteristics of cover width is big, it is suitable for the fire-fighting protection place of side dress.In order to reach preferable fogdrop diameter and the area of coverage
Domain, so as to reach preferable extinguishing effect.
The above-mentioned description to embodiment is understood that for ease of those skilled in the art and using this reality
With new.Person skilled in the art obviously can easily make various modifications to these embodiments, and saying herein
Bright General Principle is applied in other embodiment without by performing creative labour.Therefore, the utility model is not limited to
Embodiment is stated, those skilled in the art do not depart from the improvement that the utility model category is made according to announcement of the present utility model
All should be within the scope of protection of the utility model with modification.
