AI Technical Summary
Technical Problem
The button module of existing electric valve actuators is easily damaged in corrosive media environments, leading to seal failure and electrical faults, which affects the integrity of the equipment's functions.
Method used
The nested protective housing and anti-corrosion coating design, combined with a mechanical locking mechanism, form a multi-level fluid barrier to prevent corrosive liquids from contacting the button surface and seeping into the assembly gaps, ensuring sealing and circuit safety.
Benefits of technology
It effectively prevents corrosive liquids from eroding the button module, avoids seal failure and electrical faults, and improves the protection capability and service life of the equipment.

Abstract
This utility model relates to the field of actuator technology, specifically a waterproof electric valve actuator, comprising: an electric actuator body and a button module on its top, with the bottom of the body fixed to the valve body. A connecting mechanism is provided around the button module, including a snap-on cover, an upper arc cover, and a lower arc cover. The inner ring of the snap-on cover slides and snaps against the top of the body, while the outer ring is fixed to the upper arc cover. The bottom of the upper arc cover abuts against the top of the lower arc cover, and the lower arc cover is fixedly installed on the top of the body near the button module. A U-shaped plate is fixed to the top of the upper arc cover, with insertion holes at both ends; a movable insert is provided on the inner side of the lower arc cover, with one end inserted into a limiting block and the other end connected to an adjustment component. This design actively prevents corrosive liquids from contacting the button surface through a multi-level flow-guiding barrier of a nested protective shell and a dynamic seal with mechanical locking; a spring constant pressure mechanism maintains a tight fit between the components, independently preventing liquid penetration even if the button deteriorates, avoiding circuit failure due to seal failure, and ensuring safe electrical operation in corrosive environments.
