AI Technical Summary
Existing pressure gauges lack protective measures during explosion-proof testing; fragments from an explosion could injure testing personnel, making it impossible to ensure safety.
An explosion-proof safety device for pressure gauges has been designed, comprising a support plate, a mounting frame, a top plate, an electric push rod, and explosion-proof glass. The electric push rod retracts, causing the support plate to move downwards, and the top plate covers the mounting frame to form a sealed space. The explosion-proof glass blocks debris, and the explosion-proof glass can be quickly replaced.
It improves the safety of testing personnel, prevents injury from explosive fragments, is simple and convenient to operate, and ensures the safety and reliability of the testing process.
