AI Technical Summary
Existing fire pipeline air tightness testing equipment is cumbersome to operate and has a single testing method. It requires bolting to fix the flange and can only judge air tightness by air pressure gauge.
A pipeline air tightness testing device was designed, including a support platform, a first movable plate, a cylinder, a movable clamping plate, a fixed clamping plate, a cylinder, a connector, a first support, and a driving component. The driving component drives the clamping plate to move so that the cylinder abuts against both ends of the pipeline. The air tightness is tested using a pressure gauge, and the air tightness is determined by observing bubbles after immersion in water.
It enables simple operation and multiple methods for airtightness testing, improving testing efficiency and accuracy.
