The utility model provides a protection device for a valve positioner. The protection device comprises a sealing end cover, an annular installation base, a sealing assembly, a pressing mechanism and two fixing structures. The two fixing structures are arranged on the annular mounting base in a bilateral symmetry mode and detachably connected with the sealing end cover. The sealing end cover comprises an annular connecting plate, a protective end cover and an annular thickened base plate. According to the protection device for the valve positioner, the problems that due to the fact that a sealing end cover of a valve positioner shell in the related technology is poor in protection performance and sealing performance, after the valve positioner shell is collided, moisture and moisture in a humid environment can permeate into the valve positioner, and the valve positioner is damaged are solved. And thus, internal elements are damaged or corroded. 本实用新型提供了一种用于阀门定位器的防护装置，包括密封端盖、环形安装底座、密封组件、压紧机构及两个固定结构；两个固定结构左右对称设置
