The invention discloses a tire inflation and deflation device which comprises a normally-closed two-way electromagnetic valve, a normally-open two-way electromagnetic valve, an air storage tank and an inflation pipe. One end of the normally-closed two-way electromagnetic valve is connected with the air storage tank, and the other end of the normally-closed two-way electromagnetic valve is connected with the inflation pipe, so that when the normally-closed two-way electromagnetic valve is in an open state, compressed air in the air storage tank flows into a tire through the normally-closed two-way electromagnetic valve and the inflation pipe; the first end of the normally-open two-way electromagnetic valve is connected with the inflation pipe, and the second end of the normally-open two-way electromagnetic valve is communicated with the external environment, so that when the normally-open two-way electromagnetic valve is in an open state, compressed air in the tire is discharged into the external environment through the inflation pipe and the normally-open two-way electromagnetic valve. By means of the tire inflation and deflation device, when the whole device is powered off abnormally or runs abnormally, the tire is automatically deflated, and the safety of the whole device is improved.
本发明公开了一种轮胎充放气装置,包括常闭式两通电磁阀、常开式两通电磁阀、储气罐和充气管;常闭式两通电磁阀的一端与储气罐连接,另一端与充气管连接,以在常闭式两通电磁阀呈开启状态时,储气罐内的压缩气体通过常闭式两通电磁阀和充气管流入轮胎内;常开式两通电磁阀的第一端与充气管连接,常开式两通电磁阀的第二端与外界环境相通,以在常开式两通电磁阀呈开启状态时,轮胎内的压缩气体通过充气管和常开式两通电磁阀排入到外界环境中。本发明利用轮胎充放气装置实现在整体装置异常断电或运行异常时,轮胎自动放气,提高了整体装置的安全性。
