Description
Technical field
The present invention relates to a kind of gas filled device, be specifically related to a kind of inflating device for automobile tire.
Background technology
The inflating device for automobile tire used in the market has two kinds, and one is with vehicle tyre gas filled device, and it can only fill pressurized air, but the tire filling air under the high temperature conditions, easily occurs that hypertonia causes tire burst; Another kind is fixing gas filled device, can inflated with nitrogen, and volume is large, needs certain place could use, is convenient for carrying although compressed nitrogen gas cylinder volume is little, but accurately can not control inflation pressure of tire, and easy overshoot makes tire blast.
Summary of the invention
The object of this invention is to provide a kind of inflating device for automobile tire, solve Problems existing of the prior art.
Embodiment of the present invention is: a kind of inflating device for automobile tire, comprises limiting valve, butt tube, leaving air control valve, three-way pipe, pressure-measuring system and air cock, and butt tube one end is connected with limiting valve, and one end is connected with leaving air control valve.
Leaving air control valve comprises leaving air control valve body, leaving air control valve bar and spring, and described leaving air control valve body interior is provided with cavity.
Pressure-measuring system comprises pressure measuring element, change-over switch, pressure survey wiring board, pressure read-out and power supply.
Limiting valve is provided with multifunctional meter.
In high pressure tank, nitrogen is by after limiting valve second depressurized, leaving air control valve is entered through butt tube, when operating personal hand presses leaving air control valve bar, drive spring to left movement, make nitrogen in leaving air control valve body enter three-way pipe, three-way pipe connects tire, air cock and pressure measuring element respectively; When hand discharges pneumatic control valve rod, spring reset, gas passage is closed.
Pressure-measuring system loop one work is that press change-over switch, metering circuit is started working, and in three-way pipe, gaseous tension is after pressure measuring element and pressure survey wiring board, is presented on pressure read-out through computing numerical value.
Pressure-measuring system loop two work is, a kind of automotive inflator devices, and pressure-measuring system is opened after being connected with high pressure tank and tire respectively in two ends, measures gaseous tension in tire; If gaseous tension is excessive in tire, open air cock release gas to tire normal operating pressure, if gaseous tension is too small in tire, press leaving air control valve bar, drive spring to left movement, make nitrogen in leaving air control valve body enter three-way pipe, for giving tyre inflating to normal operating pressure.
The invention has the advantages that: 1) can under emergency conditions to automobile tyre inflation and reach pressure needed for tire accurately; 2) a kind of inflating device for automobile tire of the present invention is easy to carry, and use safety is efficient, exports nitrogen pressure accurate.

Detailed description of the invention
In order to make those skilled in the art better understand the present invention, below in conjunction with Fig. 1-5, the present invention is further described.
In high pressure tank, nitrogen is by after limiting valve 1 second depressurized, leaving air control valve 3 is entered through butt tube 2, when operating personal hand presses leaving air control valve bar 32, drive spring 33 to left movement, make nitrogen in leaving air control valve body 31 enter three-way pipe 4, three-way pipe connects tire, air cock 6 and pressure measuring element 51 respectively; When hand discharges pneumatic control valve rod 32, spring 33 resets, and gas passage is closed.
Limiting valve 1 is provided with multifunctional meter, for measuring pressure size and the nitrogen surplus of nitrogen in high pressure tank.
Pressure-measuring system loop one work is: press change-over switch 52, metering circuit is started working, and in three-way pipe, gaseous tension is after pressure measuring element 51 and pressure survey wiring board 53, is presented on pressure read-out 54 through computing numerical value.
Pressure-measuring system loop two work is: pressure-measuring system is opened after being connected with high pressure tank and tire respectively in two ends, measures gaseous tension in tire; If gaseous tension is excessive in tire, open air cock 6 and discharge gas to tire normal operating pressure, if gaseous tension is too small in tire, press leaving air control valve bar 32, drive spring 33 to left movement, nitrogen in leaving air control valve body 31 is made to enter three-way pipe 4, for giving tyre inflating to normal operating pressure.
