Description
Technical field
This utility model is related to fire-fighting equipment field, is specifically related to a kind of fire-fighting spraying head.
Background technology
Applicator refers under the action of heat, voluntarily start by predetermined temperature range, or according to fire signal by controlling
Control equipment starts, and a kind of shower nozzle of the watering shape by design and flow fire extinguishing water, and bulb sprinkler head is common
A kind of applicator, its heat-sensitive element is glass bead, when shower nozzle is heated, because the working solution in glass bead is had an effect, makes
Spheroid bursts and opens.Existing thermoinduction applicator is by splash box, water sputtering to be scatter, but due on shower nozzle
The water on splash box that sprays and rebound forms fixing parabola, the therefore limited area of water covering, especially for shower nozzle just
Some regions of lower section are it is impossible to cover.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fire-fighting spraying head, using the teaching of the invention it is possible to provide bigger watering model
Enclose, eliminate the blind area immediately below shower nozzle.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is as follows：A kind of fire-fighting spraying head, its feature
It is：Including main body, the U-shaped support, glass bead, seal receptacle and the nozzle that are arranged at main body lower end, be provided with current in described main body
Passage, the upper and lower ends of water stream channel are provided with water inlet and outlet, described glass bead be arranged in seal receptacle and U-shaped support it
Between, seal receptacle blocks the outlet of main body under the support of glass bead, and described nozzle is movably arranged at the current of main body
In passage, when seal receptacle removes from outlet, nozzle stretches out from outlet, and the bottom of described nozzle and side wall are evenly distributed with
Hole for water spraying.
Further, described nozzle tip forms outer, and described water stream channel inner bottom part forms interior edge, when seal receptacle is from going out
When the mouth of a river removes, nozzle moves down, and makes edge in the abutting of outer.
Further, it is provided with sealing ring between described outlet and seal receptacle.
Further, described U-shaped support includes two vertical connecting portions and the supporting part being arranged between connecting portion, institute
State supporting part and be provided with tapped through hole corresponding with outlet, in this tapped through hole, be provided with screw, the top of described screw abuts
Glass bead.
Further, described main body and U-shaped support are integrally formed.
Seen from the above description, the fire-fighting spraying head that this utility model provides is sprinkled water by shower nozzle, using the teaching of the invention it is possible to provide more
Big watering scope, can cover the region of shower nozzle bottom simultaneously, eliminate the blind area immediately below shower nozzle.
Brief description
Fig. 1 is the structural representation of this utility model fire-fighting spraying head.
Fig. 2 is the sectional view of this utility model fire-fighting spraying head.
Fig. 3 is the use schematic diagram of this utility model fire-fighting spraying head.
Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
As depicted in figs. 1 and 2, fire-fighting spraying head described in the utility model, including main body 1, is arranged at main body 1 lower end
U-shaped support 2, glass bead 3, seal receptacle 4 and nozzle 5, main body 1 and U-shaped support 2 are integrally formed, and are provided with water stream channel in main body 1
11, the upper and lower ends of water stream channel 11 are provided with water inlet 12 and outlet 13, and glass bead 3 is arranged in seal receptacle 4 and U-shaped support 2
Between, U-shaped support 2 includes two vertical connecting portions 21 and the supporting part 22 being arranged between connecting portion, and supporting part 22 sets
There is tapped through hole corresponding with outlet 13, in this tapped through hole, be provided with screw 221, the top of screw 221 abuts glass bead 3,
Seal receptacle 4 blocks the outlet 13 of main body 1 under the support of glass bead 3, is provided with sealing ring between outlet 13 and seal receptacle 4
41, the bottom of nozzle 5 and side wall are evenly distributed with hole for water spraying, and nozzle 5 is movably arranged in the water stream channel 11 of main body 1,
The bottom of nozzle 5 abuts seal receptacle 4 top, nozzle 5 top formation outer 51, water stream channel 11 inner bottom part formed interior along 14, when
When outlet 13 removes, nozzle 5 moves down seal receptacle 4, make outer 51 abut in along 14, nozzle 5 stretches out from outlet 13.
As shown in figures 1 and 3, glass bead 3 be warming fire-fighting glass bead, glass bead 3 built with working solution, glass bead 3
Explosion temperature at 70-80 degree Celsius, when run into fire and reach glass bead 3 explosion triggering temperature when, working solution expand make glass
Glass ball 3 explosion, seal receptacle 4 is driven by hydraulic pressure and deadweight, makes outlet 13 open, and now nozzle 5 moves down and from going out
The mouth of a river 13 is stretched out, and water sprays out via the hole for water spraying of nozzle 5, the larger scope of uniform covering.
Above are only some specific embodiments of the present utility model, but design concept of the present utility model is not limited to
This, all changes that using this design, this utility model is carried out with unsubstantiality, infringement this utility model protection domain all should be belonged to
Behavior.
