AI Technical Summary
Existing building water supply and drainage pipes are prone to freezing in low-temperature environments, leading to blockages or ruptures. Existing external insulation measures are ineffective in extremely cold regions, and there is a lack of internal anti-freezing design.
It adopts an antifreeze device with a built-in hollow shaft and spiral blades, combined with electric heating wire and electric heat tracing. The spiral blades disturb the water flow and automatically heat it at low temperatures. It works with a temperature controller and water temperature sensor to achieve closed-loop control. External insulation cotton and insulation shell reduce heat loss.
It effectively prevents ice formation on the inner wall of pipes, reduces the risk of blockage and rupture, ensures smooth water flow, saves energy and is environmentally friendly, and is suitable for extremely cold environments.
