The central charging and deflating relay valve has large spring journey, and the through diameter of an air channel is large and the speed of charging and deflating is rapid; the central charging and deflating relay valve is unable to heat compared with a magnetic valve, and the utilizing life is long; and the central charging and deflating relay valve has simple structure and is more economical than the magnetic valve.
Description
Technical field
The utility model relates to a kind of vehicle charging and discharging valve, relates in particular to the central inflation-deflation relay valve of a kind of cross-country vehicle tire.
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 well promote the performance of automobile tire central air-charging and air-discharging system 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 relay valve in the present automobile tire central air-charging and air-discharging system as yet.
Summary of the invention
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect that prior art exists, and provides a kind of automobile tire central inflation-deflation relay valve.
The purpose of this utility model is achieved in that
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.
The utility model comprises cylinder (1), snap ring (2), cylinder cap (3), first spring (4), second spring (5), guide rod (6), lip-type packing (7), guide pin bushing (8), O shape circle (9), the 2nd O shape circle (10), bar cover (11), rubber cushion (12), pad (13), Cross Recess Head Screw (14), sintered copper (17).
Its working principle is:
The utility model only provides a valve assembly, is matching used with special detection control system.
When not having air-flow to enter in cylinder (1) chamber from A mouth (a), first and second spring (4,5) is in original state, be crushed on the interface of module (16) at rubber cushion (12) under the effect of length of spring compressed power, two interfaces of module (16) turn-off, and then automobile tire central authorities inflation-deflation relay valve is in off working state; Otherwise, when air-flow entered in cylinder (1) chamber from A mouth (a), first and second spring (4,5) was compressed, and was pressed in rubber cushion (12) on the interface of module (2) along with moving on the guide rod (6), two interface UNICOMs of module (2), then automobile tire central authorities inflation-deflation relay valve is in running order.
The utlity model has following advantage and good effect:
1, spring travel is big, makes that the air flue latus rectum is big, and it is fast to charge and discharge gas speed;
2, can not generate heat long service life with respect to solenoid valve;
3, simple in structure, than solenoid valve economy.
