Abstract
The invention discloses the central inflation-deflation over-flow shuttle valve of a kind of automobile tire, relate to a kind of vehicle charging and discharging valve.The present invention includes shuttle valve and relief valve; Shuttle valve is made up of shuttle valve valve body (1), piston (2), spring (3); Relief valve is made up of relief valve valve body (4), diaphragm (5), packing ring (6), spring (7), nut (8), release handle (9); In shuttle valve valve body (1) chamber, piston (2) right-hand member is pressed in shuttle valve valve body (1) chamber left end by spring described in the shuttle valve (3) with piston (2), shuttle valve valve body (1) and relief valve valve body (4) are by being threaded, relief valve valve body (4) also is by being threaded with release handle (9), diaphragm (5) and packing ring (6) are housed between relief valve valve body (4) and release handle (9), and the described spring (7) in the relief valve is contained between diaphragm (5) and the nut (8).Air flue latus rectum of the present invention is big, and it is fast to charge and discharge gas speed; Compact structure, volume is little, is convenient to assembling; Release handle is housed, can regulates the gas speed that charges and discharge arbitrarily.
Description
Technical field
The present invention relates to a kind of vehicle charging and discharging valve, relate in particular to a kind of automobile tire central authorities inflation-deflation over-flow shuttle valve of cross-country vehicle tire central air-charging and air-discharging system.
Background technique
The main effect of automobile tire central air-charging and air-discharging system is: when automobile during by soft terrain such as desert, coastal beach, marsh, slob and ice and snow road, can reduce tire pressure apace by this system, increase the contact area of tire, improve the passing ability of automobile.
When the height of transporting cars is limited by bridge opening, culvert, mother aircraft hatch door etc., in certain scope,, the automobile total height is suitably reduced, just can pass through smoothly if reduce tire pressure.
When automobile tire is punctured with quilt that attack is worn,, can make automobile leave the danger zone as early as possible or arrive the destination if can give in the process of moving automobile tyre inflation in real time.
When the higher and automobile long-distance of road environment temperature travels continuously,, may cause tyre break because the tire heating raises the tire internal air pressure; If can give the venting of automobile tire in the process of moving in real time, can avoid the generation of dangerous situation.
Military offroad vehicle is when transporting weaponry, vehicular weapons system, traffic guidance system and the battlefield wounded, slow down impact and vibration if can adjust tire pressure in real time, can strengthen mobility, Security and the vital capacity of military supplies according to different condition of road surface.
In view of the above characteristic of automobile tire central air-charging and air-discharging system,, then will promote the performance of automobile tire central air-charging and air-discharging system well if the speed that tire is charged and discharged gas obviously increases.Present automobile tire central air-charging and air-discharging system is to adopt solenoid valve to control the circulation of air flue mostly, because the restriction of this body structure of solenoid valve, its circulation bore is less when solenoid valve is opened, and it is slower to cause charging and discharging gas speed, when particularly full vehicle tyre charges and discharge simultaneously.
Do not find to adopt automobile tire central authorities inflation-deflation over-flow shuttle valve in the present automobile tire central air-charging and air-discharging system as yet.
Summary of the invention
Purpose of the present invention just is to overcome the above-mentioned shortcoming and defect that prior art exists, and a kind of automobile tire central authorities inflation-deflation over-flow shuttle valve of cross-country vehicle tire central air-charging and air-discharging system is provided.
The object of the present invention is achieved like this:
Design a kind of Pneumatic valve and replace the control of solenoid valve to the central air-charging and air-discharging system air flue, solenoid valve only helps out in central air-charging and air-discharging system.
As Fig. 1, the present invention includes shuttle valve and relief valve; Shuttle valve is made up of valve body (1), piston (2), spring (3); Relief valve is made up of relief valve valve body (4), diaphragm (5), packing ring (6), spring (7), nut (8), release handle (9).
Working principle of the present invention is:
The present invention only provides a valve assembly, is matching used with special detection control system.
When not having air-flow to enter in shuttle valve valve body (1) chamber, piston (2) is in left end under the thrust of spring (3), and then the present invention is in off working state; When air-flow entered in shuttle valve valve body (1) chamber from A mouth (a), under the effect of air pressure, spring was compressed, and piston moves to right to right-hand member, and air-flow flows out from B mouth (b), and then automobile tire central authorities inflation-deflation over-flow shuttle valve is in the inflation working state; During venting, do not have air-flow to enter in shuttle valve valve body (1) chamber from A mouth (a), spring (3) resilience promotes piston (2) and moves to left to left end, air-flow enters in shuttle valve valve body (1) chamber and through relief valve from B mouth (b) and discharges, and then automobile tire central authorities inflation-deflation over-flow shuttle valve is in the venting working state.
The present invention has the following advantages and good effect:
1, the air flue latus rectum is big, and it is fast to charge and discharge gas speed;
2, compact structure, volume is little, is convenient to assembling;
3, release handle is housed, can regulates the gas speed that charges and discharge arbitrarily.
