The invention provides a loading and unloading brake interlocking system of a liquid tank semitrailer; the system comprises a normally-closed pneumatic control valve, a pneumatic control switch, a brake chamber, an air cylinder and an unloading valve, an air inlet end of the pneumatic control valve is connected with an air outlet end of the brake chamber, the air outlet end of the pneumatic control valve can exhaust air, a pneumatic end of the pneumatic control valve is connected with the air outlet end of the pneumatic control switch. The air inlet end of the pneumatic control switch is connected with the air cylinder, the other air outlet end of the pneumatic control switch is connected with the unloading valve, and the brake chamber is used for enabling the liquid tank semitrailer to be in a brake state when air pressure in the brake air chamber does not reach preset air pressure. The problem that in the prior art, when an oil tank semitrailer unloads materials, safety is not high is effectively solved.

    本发明提供一种液罐半挂车装卸制动连锁系统,包括常闭式气控阀、气控开关、制动气室、储气筒、卸料阀,所述气控阀的进气端与所述制动气室的出气端连接,所述气控阀的出气端可排气,所述气控阀的气动端与所述气控开关的出气端连接,所述气控开关的进气端与所述储气筒连接,所述气控开关的另一出气端与卸料阀连接,所述制动气室用于在当制动气室内未达到预设气压时所述液罐半挂车处于制动状态。本发明有效解决了传统技术中油罐半挂车卸料时安全性不高的问题。
