Stricture of vagina connected mode is provided with: for showing the Pressure gauge 4 of pressure in tire, for spraying gaseous state or the spray of liquid carbon dioxide 2
Mouth 5, connection tank body 1 inner chamber are to improve the relief valve 14 of safety.
The interior intracavity of valve body 3 is provided with a set of spool 6 moving up and down, is in static or mobile shape by described spool 6
State, it is achieved fire extinguishing when pressure detecting, Tyre inflating or automobile fire accident in tire.Particularly as follows: when tank body 1 is upright state
And nozzle 5 is when being connected with tyre valve, control valve conducting Pressure gauge 4 and tire under spool 6 resting state and detect in tire
Pressure, spool 6 moves rear control valve conducting nozzle 5 and tank body 1 inner chamber and ejects gaseous carbon dioxide 2 and realize filling in tire
Gas;When tank body 1 stands upside down, spool 6 moves rear control valve conducting nozzle 5 and is ejected liquid carbon dioxide with tank body 1 inner chamber by nozzle 5
2 realize fire extinguishing.
Described valve body 3 structure is: the inner chamber of described valve body 3 includes the basically identical epicoele 3-1 of internal diameter and cavity of resorption 3-2,
Having adapter cavity 3-3 between epicoele 3-1 and cavity of resorption 3-2, adapter cavity 3-3 internal diameter is less than upper and lower chamber 3-1,3-2, bottom cavity of resorption 3-2
Communicating with tank body 1 inner chamber, described Pressure gauge 4 and nozzle 5 all communicate with epicoele 3-1, and wherein Pressure gauge 4 connects epicoele 3-1's
The position of epicoele 3-1 is connected higher than nozzle 5 in position, and valve body 6 upper end connects fairlead 10, and fairlead 10 endoporus is less than epicoele 3-
The bore of 1.
Described spool 6 structure is: spool 6 includes that upper valve core 6-1 and bottom spool 6-2, described upper valve core 6-1 have directly
Hypomere, the stage casing being relatively large in diameter and the diameter epimere between hypomere and stage casing that footpath is less, the wherein stage casing of upper valve core 6-1
Being slidably matched with epicoele 3-1 inwall, upper valve core 6-1 epimere is slidably matched with the endoporus of fairlead 10, and upper valve core 6-1 epimere top
End stretches out outside fairlead 10, and the hypomere of upper valve core 6-1 is positioned at bottom epicoele 3-1;It is less that described bottom spool 6-2 has diameter
Epimere and the hypomere being relatively large in diameter, bottom spool 6-2 hypomere is positioned at cavity of resorption 3-2, and bottom spool 6-2 hypomere border and cavity of resorption 3-2
Inwall forms first annular passage 15, and bottom spool 6-2 epimere is positioned at adapter cavity 3-3, and bottom spool 6-2 epimere border and transition
Chamber 3-3 inwall forms the second circular passage 16.Cavity of resorption 3-2 bottom is provided with hollow back-up ring 7, hollow back-up ring 7 and bottom spool 6-2 hypomere
First spring 8 is installed between bottom face, bottom spool 6-2 epimere stretch in epicoele 3-1 through adapter cavity 3-3 and with upper valve core 6-
1 hypomere bottom face offsets, and on the axle step end face having, is arranged with at lower valve between the hypomere and epimere of bottom spool 6-2
The first sealing ring 9 on the hole step surface being closely attached between cavity of resorption 3-2 and adapter cavity 3-3, upper valve core 6-is sealed when core 6-2 is static
The second sealing ring 11 it is provided with between 1 periphery, stage casing and epicoele 3-1 inwall, when under upper valve core 6-1, pressure spool 6-2 moves down, upper valve core
Passage between the stage casing clossing pressure table 4 and epicoele 3-1 of 6-1 but not passage between valve nozzles 5 and epicoele 3-1.
When bottom spool 6-2 is moved down by upper valve core 6-1 effect, the first sealing ring 9 disengaging contacts with above-mentioned hole step surface,
The gap formed between first sealing ring 9 and hole step surface is constituted even with described first annular passage the 15, second circular passage 16
Logical epicoele 3-1 and the loop of tank body 1 inner chamber, thus under upper valve core 6-1 hypomere, depress spool 6-2 epimere and make bottom spool 6-2
When moving down, by above-mentioned loop conducting nozzle 5 and tank body 1 inner chamber, due to upper valve core 6-1 stage casing the clossing pressure table 4 moved down
And passage between epicoele 3-1 but not passage between valve nozzles 5 and epicoele 3-1 inner chamber, the gaseous state in tank body 1 or liquid two
Carbonoxide 2 can lead to nozzle 5 by described loop and eject.
Described valve body 6 is provided with down the pressure spanner down being pressed in upper valve core 6-1 epimere top and promote upper valve core 6-1 to move down
12, described pressure spanner 12 down, in scissor-shaped, is motion bar above it, below for fixing bar, simultaneously on upper valve core 6-1 hypomere
Being set with under keeping when upper valve core 6-1 rises and resets presses the motion bar of spanner 12 to be in the second spring of extreme higher position all the time
13。
Use process is sketched: tank body 1 is in upright state, and nozzle 5 connects with tyre valve, and spool 6 is in quiet
Only state, now can show pressure in tire by Pressure gauge 4;When showing that in tire, insufficient pressure need to be inflated, hold down and press
Spanner 12, crawl pressure is pressed down the motion bar of spanner 12, is promoted upper valve core 6-1 to move down, now upper valve core 6-1 stage casing bottom end closure
Live in the passage between chamber 3-1 and Pressure gauge 4, but still communicate between nozzle 5 with epicoele 3-1 inner chamber, under upper valve core 6-1 hypomere
After pressure spool 6-2 epimere, the first sealing ring 9 departs from and the contacting of hole step surface, in tank body 1 carbon dioxide 2 of gaseous state via
The loop that the gap formed between first annular passage the 15, first sealing ring 9 and hole step surface and the second circular passage 16 are constituted,
Spray to Tyre inflating by epicoele 3-1 from nozzle 5, owing to using some flowing mode, therefore, at the first spring 8 and the second spring
Under the common effect of 13, upper valve core 6-1 stage casing is moved, the motion bar Rapid reset of lower pressure spanner 12, pressure can be observed the most again
Pressure condition on table 4, during crawl pressure next time pressure spanner 12 down, gives Tyre inflating once more, and the circulation that goes round and begins again is above-mentioned dynamic
Make, meet the requirements until tire is intrinsic pressure.And when inflating, use crawl pressure to press down the mode of spanner 12, it is to prevent ultralow temperature
Liquid carbon dioxide 2 Long contact time tyre valve and freezing valve inside;If need fire extinguishing, then tank body 1 is stood upside down,
Hands normal pressure is stayed and is pressed spanner 12, closes the passage between epicoele 3-1 and Pressure gauge 4, carbon dioxide 2 source of liquid in tank body 1
Source constantly sprays from nozzle 5, region on fire is carried out fire extinguishing and puts out a fire to save life and property.
The present invention integrates the fire extinguishing of fire and puts out a fire to save life and property and tyre inflating, and simple in construction uses easy to carry, can be at any time
Pressure in detection automobile tire, it is ensured that vehicle is in good running status, improves travel safety, pressure in detection tire
Time not enough, Tyre inflating can be given easily and quickly, operate Portable power saving, once breaking out of fire, can quickly put out initial fire
Feelings.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and is carried out, and can not limit the scope of the invention with this, all according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within the scope of the present invention.
