The invention discloses an automobile fuel tank isolating valve and a valve element sealing structure, a valve element body is provided with a columnar structure, and a sealing fixing part extending in the axial direction is arranged in the middle of one end of a valve element; the sealing body is located at one end of the valve element body, a matching groove matched with the sealing fixing part is formed in the end, facing the valve element body, of the sealing body, and a sealing lip annularly extending in the axial direction is arranged at the end, away from the valve element body, of the sealing body. According to the valve element sealing structure of the automobile fuel tank isolating valve with the optimized design, a rubber part is structurally designed to be in a head round bowl opening thin lip form, stress deformation is sensitive, contact is consistent, and the sealing performance is better.
本发明公开了一种汽车油箱隔离阀及阀芯密封结构,阀芯体具有柱状结构,阀芯一端中部设有沿轴向伸出的密封固定部;密封体位于阀芯体一端,密封体朝向阀芯体一端设有与所述密封固定部配合的配合槽,密封体远离阀芯体一端设有围绕轴向环形延伸的密封唇。通过上述优化设计的汽车油箱隔离阀的阀芯密封结构,橡胶件的结构设计为头部圆形碗口薄唇形式,受力变形敏感,接触一致,密封性能更好。
