The invention discloses an anti-overcharging automotive LNG cylinder. The anti-overcharging automotive LNG cylinder comprises a gas cylinder body, a switch device and a control device. A gas supply pipe and a gas charging pipe are arranged at the two ends of the gas cylinder body, the switch device comprises a mounting barrel, a guide barrel, a seat plate, a fixed disc and a sliding disc, and the control device comprises a PLC, a liquid level sensor and a first electromagnetic valve. The anti-overcharging automotive LNG cylinder has the beneficial effects that the switch device and the control device are arranged, the control device is electrically connected with an external power source through the switch device, the switch device is automatically switched on in the gas charging process, and therefore the control device works; the gas amount in the gas cylinder body is measured through the liquid level sensor, when the gas amount reaches a critical value, a passage of the gas charging pipe is automatically cut off, and therefore gas charging is stopped; and according to the anti-overcharging automotive LNG cylinder, the phenomenon of overcharging of the gas cylinder body can be effectively prevented, and therefore the phenomenon of bursting of the gas cylinder body can be avoided, and the driving safety can be improved.

    本发明公布了一种防过充车用LNG气瓶,包括气瓶本体、开关装置和控制装置,气瓶本体的两端设有供气管和充气管,开关装置包括安装筒、导向筒、座板、固定盘和滑动盘,控制装置包括PLC控制器、液位传感器和第一电磁阀,本发明的有益效果是,本发明设有开关装置和控制装置,通过开关装置实现控制装置与外部电源的电性连接,在加气的过程中,开关装置自动接通,从而控制装置工作,通过液位传感器进行气瓶本体内部气量的测量,当达到临界值时,自动切断充气管的通路,从而停止加气,本发明可以有效防止气瓶本体过充现象,从而可以避免气瓶本体的炸裂现象,提高行车的安全性。
