Described rapid-release valve is made up of aie escape valve and tele-release air cock, described aie escape valve comprises the valve body being fixedly connected with, spring perch, spool and valve rod, described valve body is fixedly connected with spring perch, described spool is located between valve body and spring perch, under spool, be provided with spring and supporting plate, described spring is supported on spring perch by supporting plate, described spool covers the through hole on valve body under the effect of spring, by external atmosphere pressure and the isolation of motor tire internal gas pressure, described spool is fixedly connected with valve rod, described valve rod upper end is supported in the pilot hole of valve body, described valve rod top is provided with tele-release air cock, described tele-release air cock action can promote valve rod downwards.
Described tele-release air cock comprises the switch case with air bleed hole being connected with valve body, in described switch case, be provided with the piston with wire, piston can move in switch case, under described piston, rectify valve rod, described internal piston is equipped with gunpowder, described wire one end contacts with gunpowder, and the other end and current colector electrically connect.
Described current colector can be for being around in the ring type structure on vehicle wheel hub cap cylindrical, can be also the tray type structure being affixed on vehicle wheel hub cap side.
Urgent bleeding device has lasting failure-free power source designed according to this invention, for the trouble free service of urgent bleeding device provides basic guarantee.
Accompanying drawing explanation
Fig. 1 is the structural representation that carbon-brush holder contacts with current colector;
Fig. 2 is the structural representation of rapid-release valve;
Fig. 3 is the schematic diagram of control panel.
The specific embodiment
Under valve rod 7 explosive force that moment produces after gunpowder is lighted, move downwards with spool 9, force inside tires and ambient atmosphere to connect, thereby make tire pressure release.Gunpowder is contained in piston 4 inside, and piston 4 upper ends are provided with piston head 16, and wire 1 one end contacts with the gunpowder in piston 4 through piston head 16, and the other end is connected with current colector 2.Piston 4 activities are located in switch case 5, on switch case 5 sidewalls, offer air bleed hole 14, the outer round surface of piston 4 is provided with annular groove, in this groove, be provided with retaining ring 3, switch case 5 inwalls corresponding with this retaining ring 3 are provided with circular groove 17, circular groove 17 cross section indentions, while work, retaining ring 3 sinks in circular groove 17, in relaxation state, in the time that piston 4 moves, retaining ring 3 is by the compressed circular groove 17 that leaves, because retaining ring 3 has elasticity, retaining ring 3 is close to switch case 5 inwalls, under the effect that there is no enough external force, piston 4 can be stuck in the optional position of switch case 5 inwalls.
Above-mentioned formation electric firing lock.After switch ignition, the valve rod 7 that piston 4 is pushing away aie escape valve moves downwards.Aie escape valve comprises valve body 6, spring perch 11, spool 9 and valve rod 7, be cast with rubbery outer cover 12(in spring perch 11 outsides and also can be full metal jacket), rapid-release valve can be arranged on automotive wheel by this rubbery outer cover 12, valve body 6 is fixedly connected with spring perch 11 use screw threads, between valve body 6 cylindricals and spring perch 11 endoporus, be provided with O RunddichtringO 18, spool 9 is located between valve body 6 and spring perch 11, under spool 9, be provided with spring 10 and supporting plate 19, spring 10 is supported on spring perch 11 by supporting plate 19, spool 9 upper surfaces are close on the packing seal 8 that is located at valve body 6 bottom surfaces under the effect of spring 10, cover the through hole 20 that valve body 6 is provided with, external atmosphere pressure and motor tire internal gas pressure are separated, spool 9 is fixedly connected with valve rod 7, the upper end of valve rod 7 is supported in the pilot hole 21 of valve body 6, valve rod 7 tops are provided with described air cock, it is downward that the action of tele-release air cock can promote valve rod 7.Visible the applicant of detailed operation principle of rapid-release valve is called the utility model patent (patent No.: 200920007746.X) of " automobile emergency parking apparatus " in the name of application on February 7th, 2009.
Rapid-release valve has substituted original cranked tire valve, its wire 1 is connected with the current colector 24 being arranged on wheel hub cover 23, and a carbon-brush holder 25 is installed on vehicle frame 27, this carbon-brush holder 25 can be contained in support side or other positions that can conveniently install additional of wheel cylinder, allow the carbon brush 26 of carbon-brush holder 25 facing to current colector 24, and keep suitable contact, so just forming flexible lamp connects, and the other end of carbon brush 26 access firing button 31, this firing button 31 is integrated in that on a control panel, (this firing button can be manual, also interlock can utilize brake pedal brake time, step on brake pedal do not loosen on earth just can switch on to igniting open valve pressure release), this control panel is electrically connected with automobile storage battery.Control panel also has the whether normal standby indicating lamp 30 of tele-release air cock of the rapid-release valve on source switch 28, power light 29 and four tires of four indications.In the time of standby, do not work if any a standby indicating lamp 30, show that this line is connected with the interior broken string of piston of the tele-release air cock of problem or rapid-release valve, reminds on-call maintenance.Urgent bleeding device is due to the storage battery effect power supply that utilizes automobile to carry designed according to this invention, therefore it has lasting failure-free power source, for the trouble free service of urgent bleeding device lays the first stone, also for replacing explosion type valve switch, exploitation electromagnetism (moving) valve switch creates favorable conditions simultaneously.
