Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-5, a kind of anti-overfilling device of big volume automobile natural gas bottle, including buffering bottle 1, small envelope
First 2, end socket support plate 3, drainage tube 4, sealing plate 5, interior rear head 6, rear supporting tube 7, small pipe cap 8, stiffening plate 9, stiffener plate 10
And natural gas bottle；It is characterized in that：1 both ends open of buffering bottle, buffering to be welded on the inner wall of bottle 1 has stiffener plate
10, stiffener plate 10 will buffer bottle 1 and divide for several small shell rings 11, and the connection of stiffener plate 10 and buffering 1 inner wall of bottle
Place offers semicircular drag reduction hole 12；The small end socket 2 be welded buffering bottle 1 one end, buffer bottle 1 the other end with
The interior rear head 6 of natural gas bottle is welded and fixed, and end socket support plate 3 is welded in the inside of small end socket 2, small pipe cap 8 be welded including after
On the inner wall of end socket 6, and small pipe cap 8 is located inside buffering bottle 1；One end of the rear supporting tube 7 pass through interior rear head 6 and with
Small pipe cap 8 is welded and fixed, and the stiffening plate 9 of copper coin shape is sleeved on rear supporting tube 7, and the outer ring of stiffening plate 9 and interior rear head 6 is outer
Wall is welded and fixed, and inner ring and the rear supporting tube 7 of stiffening plate 9 are welded and fixed；The 180 ° of directions of one of them of the small shell ring 11 are solid
Surely there is a drainage tube 4, the other end of drainage tube 4 and lead to natural gas bottle, end face of the drainage tube 4 in natural gas bottle is fixed with
Sealing plate 5, and open up restricted orifice 13 at 5 center of sealing plate.
Wherein, a diameter of 10mm of the drainage tube 4, a diameter of 2mm of metering hole 13.
Wherein, the drainage tube 4 uses the bellows of stainless steel.
Wherein, a diameter of 25mm in the drag reduction hole 12.
When liquid has been filled with natural gas bottle 14, liquid just can enter surge flask from bottle top by drainage tube 4
Body 1, and 4 end face of drainage tube can be sealed with the sealing plate 5 for being provided with metering hole 13, and the speed flowed liquid into is slower.Thus
It can avoid while filling, liquid just has excessive part to come into inside buffering bottle 1, causes to fill excessive existing
As.
Because the pressure outside buffering bottle 1 can be reduced as gas cylinder uses, the pressure at this moment buffered in bottle 1 then can be big
In extraneous pressure, the interior medium stored will be pushed back natural gas bottle 14 by drainage tube 4, in this way when the medium in gas cylinder
When being finished, will not occur buffering in bottle 1 has the phenomenon that liquid residual.
In addition, increasing stiffener plate 10 inside buffering bottle 1, can effectively prevent because of hypertonia in buffering bottle 1
And the case where causing small end socket 2 and small shell ring 11 to deform, 10 bottom of stiffener plate are provided with the drag reduction hole 12 of R25, make it not
Liquid can be hindered in internal circulation.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
