The invention provides a built-in control valve for an automobile fuel tank, which is applied to the technical field of fuel tank control valves and is characterized in that an air hole channel is formed in the top of a valve body, a bottom end mounting seat is fixedly connected to the bottom end of the valve body, a floating core spring is fixedly connected to the top of the bottom end mounting seat, and a valve floating core is fixedly connected to the top of the floating core spring; an original air hole of the control valve is changed into a long-pipe-shaped air hole channel, the blocking valve plate is installed between the air hole channel and the valve floating core, the valve plate spring pushes the blocking valve plate to press the sealing gasket, blocking and sealing of the air hole channel are achieved, and the valve plate spring is used for buffering vertical shaking of the valve floating core. The sealing effect of the control valve is effectively prevented from being affected by shaking generated by bumping of a vehicle, when fuel oil is completely exposed out of the valve floating core, the air hole guide rod pulls down the pressing ferrule by pulling the plug pin and is matched with the connecting rib to pull the connecting rib to turn down and loosen the air distribution hole, and the air distribution hole is opened to improve the circulation effect of an air hole channel.

    本发明提供了应用于油箱控制阀技术领域的一种汽车燃油箱内置式控制阀,通过阀体的顶部开设有气孔通道,阀体的底端固定连接有底端安装座,且底端安装座的顶部固定连接有浮芯弹簧,浮芯弹簧的顶部固定连接有阀浮芯,实现将控制阀原本的气孔转变为长管状的气孔通道,在气孔通道与阀浮芯之间安装堵塞阀片,阀片弹簧推动堵塞阀片对密封垫圈压紧,实现气孔通道的堵塞密封,利用阀片弹簧对阀浮芯的上下晃动进行缓冲,有效避免车辆颠簸产生的晃动影响控制阀的封闭效果,在阀浮芯完全露出燃油时,气孔导棒通过拉动插销对按压套圈下拉,配合连接筋拉动连接筋下翻,松开分气孔,实现开启分气孔来提高气孔通道的流通效果。
