An aerosol valve device comprises a cylinder having a connecting end. An air inlet is opened on the side of the cylinder, and the air inlet is communicated with the interior of the cylinder. The air inlet is correspondingly screwed with an inlet plug. The cylinder is further correspondingly connected with a sealing unit. The sealing unit further comprises a sealing base and the sealing base is provided with a through slot penetrating the base body at the center. The periphery bottom of the sealing body is connected with a first gasket, and a second gasket is disposed in the through slot of the sealing base. Finally, the sealing unit further comprises a valve stem having a discharge tube and an input base. The discharge tube is penetrated through the through slot of the sealing base, and the input base is received within the connecting end of the cylinder. Moreover, a spring is connected between the input base and the connecting end so that the valve stem can move back and forth between the sealing base and the cylinder by the expansion and compression action of the spring.一種氣霧閥門裝置,係包括一氣缸,該氣缸係具有一連接端,於該氣缸側邊開設有一進氣孔,該進氣孔與氣缸內部連通,該進氣孔對應旋接一進氣塞,另該氣缸係對應連接一封蓋組,該封蓋組更包括一封座,於該封座中心位置係具有一貫穿座體之穿槽,於該封座周緣底面係連接一第一墊圈,再於封座之穿槽內設有一第二墊圈,最後,該封蓋組更包括一閥桿,該閥桿具有一導出管及一導入座,該導出管穿設於該封座之穿槽,該導入座容設於該氣缸之連接端內;及一彈簧,係連接於該導入座與連接端之間,使該閥桿藉由該彈簧之伸縮作用,於該封座及氣缸間來回作動。1‧‧‧氣缸11‧‧‧連接端111‧‧‧連接片12‧‧‧吸入管121‧‧‧錐形頭13‧‧‧進氣孔2‧‧‧進氣塞21‧‧‧旋座22‧‧‧阻氣座3‧‧‧吸管4‧‧‧封蓋組41‧‧‧封座411‧‧‧穿槽412‧‧‧凹槽42‧‧‧第一墊圈43‧‧‧第二墊圈44‧‧‧閥桿441‧‧‧導出管442‧‧‧導入座443‧‧‧出料孔45‧‧‧彈簧
