Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
Referring to figs. 1 to 4, a kind of Concealed fire spray head, including spray head 1, splash box 2, support base 3, cunning
Bar 4, thrermostatic bimetal-plate 5, support spring 6, power-assisted component 7.
Spray head 1 is equipped with nozzle 11, and 2 middle part top of splash box is equipped with the water blockoff head 21 cooperated with nozzle 11, water blockoff head 21
For up-narrow and down-wide type, 21 upper end of water blockoff head be equipped with can valve nozzles rubber block 22.
Support base 3 is fixed on spray head 1, and support base 3, which is equipped with, accommodates the perforation 31 that slide bar 4 passes through, slide bar 4 one
End connection splash box 2, the other end are equipped with thrermostatic bimetal-plate 5, and support spring 6,6 both ends of support spring difference are arranged on slide bar 4
Thrermostatic bimetal-plate 5 and support base 3 are held out against, thrermostatic bimetal-plate 5 includes active layers 51 and passive layer 52, passive layer 52 and active layers 51
Arrangement up and down, active layers 51 are located at close to 6 side of support spring, and active layers 51 are manganese-nickel alloy, nichrome, nickel manganese iron
One kind of alloy, passive layer 52 are dilval, and 5 non-temperature distortions of thermo bimetal, two sides spacing is greater than in support spring 6
Diameter, and then support can be provided to support spring 6, support spring 6 is limited between thrermostatic bimetal-plate 5 and support base 3；Hot double gold
After belonging to 5 temperature distortion of piece, two sides spacing is less than 6 internal diameter of support spring and is greater than 31 diameters of perforation of support base 3, and then supports bullet
Spring 6 loses support in 5 side of thrermostatic bimetal-plate and flicks, and the decline of slide bar 4 is made to open simultaneously spray head 1；5 middle part of thrermostatic bimetal-plate
Equipped with through hole 53, it is equipped with screw hole 41 at the top of slide bar 4, through hole 53 is passed through by screw rod 42 and is connect with screw hole 41 to fix hot pair
Sheet metal 5 and slide bar 4；Slide bar 4 is made of copper, and 2 bottom of splash box is equipped with thermally conductive sheet 23 made of copper, and thermally conductive sheet 23 and slide bar 4 connect
It connects, heat can be transmitted at thrermostatic bimetal-plate 5 by thermally conductive sheet 23, slide bar 4；Slide bar 4, thrermostatic bimetal-plate 5, support spring 6 are each
Equipped with multiple, thermally conductive sheet 23 connects each slide bar 4, and then it is heated to synchronize each thrermostatic bimetal-plate 5.
Power-assisted component 7 includes stressed plate 71, power assistant spring 72, guiding bar 73, and stressed plate 71 is fixed at thrermostatic bimetal-plate 5
Top, power assistant spring 72 are set between stressed plate 71 and thrermostatic bimetal-plate 15, and power assistant spring 72 provides slide bar 4 and drives splash box 2
The thrust of decline, guiding bar 73 are fixed on stressed plate 71, and guiding bar 73 and slide bar 4 are coaxially disposed, and power assistant spring 72 is arranged
In in guiding bar 73, the maximum outside diameter of power assistant spring 72 is less than the minimum diameter of support spring 6, so that power assistant spring 72 and support
Spring 6 can carry out inside and outside be arranged.
This kind of Concealed fire spray head working principle is as follows: when the fire-fighting spraying head is in close state (as shown in Figure 1, Figure 2
It is shown), support spring 6 is between support base 3 and thrermostatic bimetal-plate 5, and support spring 6 is in confined state at this time, due to
Thrermostatic bimetal-plate 5 and the locking of slide bar 4 connect, and slide bar 4 is connect with splash box 2, and then under the effect of the elastic force of support spring 6,
Thrermostatic bimetal-plate 5, slide bar 4, splash box 2 are pushed to a high position, i.e. the water blockoff head 21 of splash box 2 blocks nozzle 11, due to water blockoff
21 overheads are rubber block 22, ensure that the reliable closure of nozzle 11；When meeting with fire behavior (as shown in Figure 3, Figure 4), it is located at
The thermally conductive sheet 23 of 2 bottom of splash box is heated first, and since thermally conductive sheet 23 and each slide bar 4 are all connected with, and then heat passes through each slide bar 4
It is synchronously transmitted at each thrermostatic bimetal-plate 5, thrermostatic bimetal-plate 5 is heated, due to the thermal expansion coefficient of active layers 51 and passive layer 52
Difference, when temperature distortion, the deformation quantity of active layers 51 is greater than passive layer 52, so thrermostatic bimetal-plate 5 is whole can be towards passive layer
52 curvings, after 5 Bending Deformation of thrermostatic bimetal-plate, the spacing of two sides becomes smaller, and when two sides, spacing is contracted to be less than support bullet
When the internal diameter of spring 6, support spring 6 loses the support of 5 side of thrermostatic bimetal-plate and flicks, at this point, slide bar 4, splash box 2 lose
Support spring 6 resilient support, under the collective effect of 72 elastic force of hydraulic pressure and power assistant spring of nozzle 11, thrermostatic bimetal-plate 5,
Slide bar 4, splash box 2 drop to thrermostatic bimetal-plate 5 and reach at support base 3, after being thermally deformed due to thrermostatic bimetal-plate 5 between its two sides
Away from be greater than support base 3 perforate 31 diameters, and then thrermostatic bimetal-plate 5 can not pass through perforation；Nozzle 11 is opened at this time, and water is by nozzle
11 spray, and water dissipates in the punishment of water blockoff head 21 and disperses again on splash box 2, and water disperses around ejection；Power assistant spring 72
Effect is that providing an initial thrust band moving slide-bar 4 declines, and when nozzle 11 being avoided to be blocked completely, the hydraulic pressure of spray head is not
It is enough to wash water blockoff head 21 open, ensure that the reliability of equipment；Guiding bar 73 keeps vertical for guaranteeing when power assistant spring 72 flicks
Path, guiding bar 73 and slide bar 4 are coaxially disposed and the maximum outside diameter of power assistant spring 72 is less than the minimum diameter of support spring 6, into
And when power assistant spring 72 and support spring 6 flick completely, power assistant spring position 72 avoids power assistant spring inside support spring 6
Influencing each other between 72 and support spring 6；Thermally conductive sheet 23, slide bar 4 are copper at thermal coefficient is big, is conducive to the fast of heat
Speed passes to, and then makes the fast response time of the fire-fighting spraying head；The passive layer 52 of thrermostatic bimetal-plate 5 is located at 51 top of active layers,
Active layers 51 are located at 6 side of support spring, in 5 heated bending of thrermostatic bimetal-plate, deformation direction towards 52 side of passive layer,
51 side of active layers forms an arcwall face, which is conducive to that support spring 6 is guided to pop up.
It above are only a kind of specific embodiment of the utility model, but the design concept of the utility model is not limited to
This, all non-essential modifications to the present invention made by this concept should belong to infringement scope of protection of the utility model
Behavior.
