The invention discloses a compact tire valve of a central tire inflation and deflation system. The compact tire valve comprises a valve body, a control valve element and a one-way locking valve element, a control valve cavity for containing the control valve element is formed in the middle of the valve body, a one-way locking valve cavity for containing the one-way locking valve element is formed in the middle of a valve body top cover, a guide sleeve is arranged in the one-way locking valve cavity, the one-way locking valve comprises a guide rod arranged in a guide hole in a clearance mode and a valve element seat arranged in the middle of the guide rod, a first sealing ring is arranged outside the valve element seat, a second spring is arranged on the upper portion of the valve element seat, a first spring is mounted outside a limiting guide step, a lip-shaped sealing ring is arranged in a hole wall groove, and a sealing guide piece is arranged in a first sealing groove. Multi-stage sealing is formed on the tire valve through the lip-shaped sealing ring, the first sealing ring, the sealing guide piece and a second sealing ring, the air leakage phenomenon in the using process of the tire valve is avoided, the tire valve has the advantages of being high in integration degree and compact in structure, and the size and weight of the tire valve are reduced.

    本发明公开了一种紧凑型中央轮胎充放气系统轮胎阀,包括阀体、控制阀芯和单向锁闭阀阀芯,阀体中部设有容纳控制阀芯的控制阀腔,阀体顶盖中部设有容纳单向锁闭阀阀芯的单向锁闭阀腔,单向锁闭阀腔内部设有导向套,单向锁闭阀包括间隙地设置于导向孔内的导向杆以及设置于导向杆中部的阀芯座,阀芯座外部设有第一密封圈,阀芯座上部设有第二弹簧;限位导向台阶外部安装有第一弹簧;孔壁凹槽内部设有唇型密封圈,第一密封槽内部设有密封导向件。本发明利用唇型密封圈、第一密封圈、密封导向件以及第二密封圈对轮胎阀形成多级密封,避免了轮胎阀使用过程中漏气现象的产生,且具有集成度高、结构紧凑的优点,减小了轮胎阀的体积和重量。
