The invention relates to the technical field of automobile fuel tank sealing devices, and discloses a mechanical sealing valve with a baffle. The problem of oil splashing is solved by arranging the movable baffle at a lower oil channel opening of the sealing valve. When the movable baffle is not additionally arranged, after an oil gun is pulled out, fuel oil in the oil tank can flow out of the oil channel opening under the action of internal residual oil pressure, and if the residual oil pressure is large, the phenomenon of oil splashing can happen. And after the movable baffle is additionally arranged, when the oil flows out under the action of residual oil pressure, the movable baffle blocks the oil channel opening under the action of a springback piece, so that the oil is prevented from overflowing and even splashing. And finally, the movable baffle is a hard thin plate with colors which can be easily recognized by human eyes, and the colors which can be easily recognized by the human eyes are used for helping a user to judge whether the oil gun is normally inserted or not, so that oil filling misoperation is avoided.
本发明涉及汽车燃油箱密封装置技术领域,公开了一种带挡板的机械式密封阀,通过在密封阀的下油道口处设置一活动挡板来解决油液喷溅的问题;未加装该活动挡板时,拔出加油枪后,油箱内的燃油在内部残留油压的作用下从油道口流出,如果残余油压较大,则会产生油液喷溅的现象;而加装了活动挡板后,油液在残余油压的作用下向外流出时,活动挡板在回弹件的作用下挡住油道口,从而避免油液溢出甚至飞溅。最后,活动挡板为带有人眼易于识别的颜色的硬质薄板,利用人眼易于识别的颜色帮助用户判断加油枪是否正常插入,避免加油误操作。
