The utility model provides a shaft through type valve structure which comprises a valve shaft, a valve plate, a sealing ring and a valve shell. The valve shaft penetrates through the valve shell and is in running fit with the valve shell; the sealing ring is fixed in a groove in the side surface of the valve plate; the valve shaft and the valve plate are fixed, and the axis of the valve shaft and the center line of the valve plate are collinear. Compared with a traditional eccentric structure valve, friction to the inner wall of the valve shell can be reduced, the good sealing effect is achieved, and the structure is simple. 本实用新型提出了一种轴通式活门结构，包括活门轴、活门板、密封圈、活门壳体；所述活门轴穿过活门壳体与活门壳体之间转动配合；所述密封圈固定于活门板侧面凹槽内；所述活门轴与活门板固定，活门轴轴线与活门板中心线共线。相对于传统偏心结构活门，可以减少对于活门壳体内壁的摩擦，起到良好的密封效果，结构简单。
