Description
Technical field
This utility model relates to outdoor fire hydrant, particularly a kind of outdoor fire hydrant water draw-off.
Background technology
One drain valve, hole internal diameter about 5mm are arranged at common outdoor fire hydrant key bottom, its effect be make to be finished fire hydrant after,
Water remaining in cavity is discharged by the valve opening that sluices from pressure by fire water in fire hydrant.But sluicing valve opening is that direction is parallel to the ground, lets out
Water valve direct-burried is in underground, and soil is easily poured in down a chimney from outside by the extruding of surrounding soil layer and blocked up by sluicing valve opening after being soaked by hydrops
Plug, in relying on fire hydrant, fire water is difficult to extrude the earth of blocking at sluicing valve opening from pressure, it is impossible to ensure at sluicing valve opening logical
Road is unimpeded.Sluicing valve opening only one of which, once blocks, and remaining water cannot emptying.The northern area that temperature is relatively low in the winter time, outdoor disappears
In fire bolt cavity, remaining water can not emptying, although drain valve body is in below frozen soil layer, is unlikely to by bursting by freezing, but is exposed to outdoor ring
Easily there is freezing phenomena in the outdoor fire hydrant part at border or frozen soil layer position, and the lighter damages fire hydrant, and severe one affects fire extinguishing and rescues
Help.
Utility model content
The technical problems to be solved in the utility model is a kind of anticlogging outdoor fire hydrant water draw-off.Use following skill
Art scheme:
A kind of outdoor fire hydrant water draw-off, including fire hydrant, the drain valve connecting tube connected with fire hydrant is positioned at ground
Hereinafter, also including that side is provided with the sluicing cavity of discharge opening structure, sluicing cavity is hollow structure, and sluicing cavity one end is closed,
The other end is provided with fixes the drain valve interface being connected and communicating with the cavity that sluices, and sluicing cavity passes through drain valve interface and drain valve
Connecting tube is affixed and communicates.
Use this utility model of technique scheme compared with prior art, provide the benefit that:
Can ensure that sluicing is smooth and easy, do not block, in timely and effective emptying fire hydrant cavity, remaining water, can effectively prevent the fire that disappears winter
Bolt freezing phenomena, ensures the normal use of fire hydrant.
Further, prioritization scheme of the present utility model is:
A diameter of 8 millimeters of discharge opening.
The quantity of discharge opening is multiple.
Sluicing cavity be shaped as spheroid, spheroid, cylinder or cuboid.
Sluicing chamber outer surface scribbles painting anticorrosive paint.
Accompanying drawing explanation

In figure: fire hydrant 1；Real soil layer 2；Rock layer 3；Drain valve connecting tube 4；Sluicing cavity 5；Sluicing cavity body 5-1；
Spilled water hole 5-2；Drain valve interface 5-3；Fire hydrant water inlet pipe 6；Fire hydrant pedestal 7；Elbow 8.
Detailed description of the invention
In Fig. 1, the present embodiment includes that fire hydrant 1, fire hydrant 1 lower half locate below ground level, and the lower end of fire hydrant 1 is with curved
8 connect, and elbow 8 other end is connected with fire hydrant water inlet pipe 6, and elbow 8 outer surface is rigidly connected with fire hydrant pedestal 7.Disappearing
The side of fire bolt 1 lower end is provided with drain valve connecting tube 4, and drain valve connecting tube 4 one end is welded to connect with fire hydrant 1, and drain valve is even
Adapter 4 other end is provided with external screw thread, and the outer end of the drain valve interface 5-3 of sluicing cavity 5 is provided with female thread, and sluicing cavity 5 passes through
Drain valve interface 5-3 is threadeded with drain valve connecting tube 4.Shown in sluicing cavity 5(Fig. 2, Fig. 3) it is hollow structure, it is shaped as
Spheroid, spheroid, cylinder or cuboid；Sluicing cavity body 5-1 one end is closed, the other end and drain valve interface 5-3 one end
Fixing connect, connected mode for being welded to connect, bolted flanged connection or threaded；Side opening in sluicing cavity body 5-1
There are 12 16 discharge opening 5-3, a diameter of 8 millimeters of discharge opening 5-3；Sluicing cavity 5 outer surface scribbles painting anticorrosive paint.
The present embodiment, when installing for the first time, excavates around outdoor fire hydrant 1 that 1.2m × 1.2m is square, the degree of depth is that 1.5m is left
The right underground space.Fire hydrant bottom elbow 8 and fire hydrant pedestal 7 are exposed；By the drain valve interface 5-3 of sluicing cavity 5 with
Drain valve connecting tube 4 is threaded, and spilled water hole 5-2 down, and carries out 1.6MPa pressure sealing, open and close and drain function survey
Examination, carries out burying after test passes filling out.Bury when filling out, diameter 50mm-80mm must be used in the range of device surrounding circumference is not less than 0.5m
Goose soft rock or stone be piled into rock layer 3: the laying of rock layer 3 needs first laying apparatus bottom stone, it is ensured that after safe, can
Continue the stone on laying apparatus top；Laying upper strata and exceed device top 100mm, lower floor lays to duct bottom 200mm, so
Be beneficial to attract deposit more than fire hydrant intracavity water and place water drainage hole plug.Rock layer 2 and pad soil layer 2 to filling out between ground and press
Real.
The foregoing is only the embodiment that this utility model is the most feasible, not thereby limit to power of the present utility model
Profit scope, the equivalent structure change that all utilization this utility model description and accompanying drawing content are made, it is both contained in this utility model
Interest field within.
