According to the cut-off interlocking device for the dangerous goods liquid tank truck, when a loading and unloading crane pipe opening is broken, the pressure detected by a pressure detector 4 is lower than a pressure threshold value, a controller 7 immediately turns off a cut-off switch 3, and leakage of dangerous goods liquid is avoided; when the temperature detected by the temperature detector 4 is larger than a temperature threshold value, the controller 7 immediately turns off the cut-off switch 3, and accidents caused by abnormal temperature of the hazardous liquid are avoided. After loading and unloading are completed, the cut-off switch 3 is turned off, the buoyancy detector 2 monitors that if buoyancy exists in a pipe cavity at the connecting position of the tank car connector 1 and the tank car loading and unloading opening, the information that the residual dangerous goods liquid exists between the tank car connector 1 and the tank car loading and unloading opening is fed back to the controller 7, and the controller 7 triggers the warning indicator 8 to remind workers of illegal operation. The valve of the loading and unloading port of the tank car is not closed, so that accidents such as leakage of a loading arm are avoided in the actual loading and unloading process.
本发明提供了一种危险品液体罐车切断联锁装置,当装卸鹤管口断裂,则压力检测器4测得的压力低于压力阈值,所述控制器7立即关闭切断开关3,避免危险品液体泄漏;当温度检测器4测得的温度大于温度阈值,所述控制器7立即关闭切断开关3,避免因危险品液体的温度异常而出现事故;当装卸完成后,关闭切断开关3,浮力检测器2监测槽车接头1和槽车装卸口连接处管腔内如果存在浮力,则将所述槽车接头1和槽车装卸口之间存有残留危险品液体的信息反馈给控制器7,控制器7引发警示器8提示工作人员违规操作,未关闭槽车装卸口的阀门,以解决在实际的装卸车过程中,避免鹤管泄露等事故的问题。
