The places such as book shop, skyscraper, garage are strict to fire-fighting safety requirements, and fire water pressure request is important to, to meet that fire-fighting will
Ask, when ensureing to occur fire-fighting accident, effectively emergency system and fire suppression measures.
But because hydraulic pressure is too high, valve rod is easily rushed out fire hydrant, then has substantial amounts of water and be lost in from fire hydrant, wave
Take resource, in order to prevent water from scattering everywhere, people often close fire water supply, if repairing not in time, fire-fighting system can deposit
In great potential safety hazard, and fire hydrant maintenance difficult, maintenance personal typically use and change whole fire hydrant, equipment cost
Height, investment are big.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of above ground hydrant, to solve existing fire hydrant
Valve rod the problem of easily being gone out by hydraulic pressure.
Above ground hydrant provided by the utility model, including：Key and top cover, top cover are threaded in the top of key,
Key includes roof, bottom wall and side wall, and for side wall between roof and bottom wall, side wall forms exhalant canal, and bottom wall forms water inlet
Passage, exhalant canal are connected with intake tunnel, and valve rod is provided with key, and valve rod includes the cylinder and circle of integrative-structure
Stage body, round estrade are located at the lower section of cylinder, and the basal diameter of round estrade is identical with the diameter of intake tunnel；Cylinder passes through limit
Position post is suspended in key, offers the through hole of strip in cylinder, and limited post passes through through hole, and both ends respectively with roof
It is fixed；And the position on bottom wall above the bottom surface of round estrade offers rhone, rhone is circumscribed with drainpipe,
Valve is provided with drainpipe.
Additionally, it is preferred that structure be that the inlet diameter of exhalant canal is more than the outlet diameter of exhalant canal.
Compared with prior art, the utility model has the advantage of：
1st, the motion of valve rod is limited by the limited post being fixed on key roof, prevents valve rod from going out key by hydraulic pressure；
2nd, by the up and down motion of round estrade, it is turned on and off intake tunnel；
3rd, the water of residual is drained by rhone in intake tunnel；
4. inclined side wall can prevent exhalant canal ponding.
Brief description of the drawings
By reference to the explanation and the content of claims below in conjunction with accompanying drawing, and with to it is of the present utility model more
Comprehensive understanding, other purposes and result of the present utility model will be more apparent and should be readily appreciated that.In the accompanying drawings：
Fig. 1 is the overall structure diagram according to the above ground hydrant of the utility model embodiment.
Reference therein includes：Key 1, roof 11, bottom wall 12, intake tunnel 121, side wall 13, exhalant canal
131st, top cover 2, valve rod 3, cylinder 31, round estrade 32, limited post 4, safety head 5, rhone 6, drainpipe 7, valve 8.
Identical label indicates similar or corresponding feature or function in all of the figs.
Embodiment
Specific embodiment of the utility model is described in detail below with reference to accompanying drawing.
Fig. 1 shows the structure of the above ground hydrant according to the utility model embodiment.
As shown in figure 1, above ground hydrant provided by the utility model, including：Key 1 and top cover 2, top cover 2 are threadedly coupled
At the top of key 1, key 1 includes roof 11, bottom wall 12 and side wall 13, and side wall 13 is between roof 11 and bottom wall 12, side
Wall 13 forms exhalant canal 131, and bottom wall 12 forms intake tunnel 121, and exhalant canal 131 is connected with intake tunnel 121, in bolt
Valve rod 3 is provided with vivo, valve rod 3 includes the cylinder 31 and round estrade 32 of integrative-structure, and cylinder 31 is located at round estrade 32
Top, cylinder 31 are suspended in key 1 by limited post 4, offer the through hole of strip in cylinder 31, through hole it is straight
Footpath is slightly larger than the diameter of limited post 4, and limited post 4 passes through through hole, and both ends are fixed with roof 11 respectively, and the length of through hole will ensure
When limited post 4 contacts with the bottom of through hole, round estrade 32 moves upward out intake tunnel 121（Round estrade 32 turns on intake tunnel
121 with exhalant canal 131）While, the top of cylinder 31 can not contact with top cover 2, i.e., valve rod 2 can not go out key 1；Circle
The basal diameter of stage body 32 is identical with the diameter of intake tunnel 121, and when valve rod 2 does not receive hydraulic pressure impact, round estrade 32 is located at
In intake tunnel 121, the connection of intake tunnel 121 and exhalant canal 131 is blocked, when using above ground hydrant, round estrade 32
Rushed upwards in the presence of hydraulic pressure, when round estrade 32 goes out intake tunnel 121, intake tunnel 121 connects with exhalant canal 131
Logical, current spray from exhalant canal 131, when round estrade 32 rushes upwards, limitation valve rod 3 are carried out by limited post 4 spacing, prevented
Only valve rod 3 is rushed out key 1, and limited post 4 can also play a part of guiding to valve rod 3；When having used above ground hydrant, valve rod
2 fall after rise to initial position, because round estrade 32 has gradient, the water of residual can be made to gather together.
For the sake of security, safety head 5 is threaded with the delivery port of exhalant canal 131, safety head 4 plays anti-leak-stopping
The effect of water.
When having used above ground hydrant, in order to prevent the ponding of exhalant canal 131, side wall 13 is obliquely installed, and specifically, is gone out
The inlet diameter of aquaporin 131 is more than the outlet diameter of exhalant canal 131, makes the aqueous reflux that exhalant canal 131 remains back into water
In passage 121.
In order to drain the water of residual in intake tunnel 121, round estrade 32 is close on bottom wall 12（In the raw
Under, i.e., state during hydraulic pressure impact is not received）At least one oblique rhone 6, oblique draining are offered above bottom surface
Groove 6 plays a part of water conservancy diversion, and rhone 6 is circumscribed with drainpipe 7, and valve 8 is provided with drainpipe 7, is controlled and arranged by valve 8
The on and off of water pipe 7.
