Pipe Airflow Regulator With Rotating Seal for Flush Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air flow regulation devices in pipes face challenges with protruding calibrating elements that complicate installation, particularly when maximizing air flow, as they require sealing without obstructing the pipe circumference.
Innovation Solution
A device with a rotatable sealing wall and adjustable calibrating element that translates perpendicular to the flap's axis, ensuring the sealing wall does not protrude from the pipe circumference, allowing for maximum air flow regulation without obstructing the pipe's circumference.

1Productivity
If the calibrating element is positioned to allow maximum air flow, then the air flow capability is improved, but the front face protrudes from the duct circumference making installation difficult
Solution Approach 1:
The sealing wall is made rotatable relative to the duct, allowing it to change orientation from a protruding position to a retracted position within the duct circumference. This dimensional change in orientation allows the calibrating element to achieve maximum air flow capability while the sealing wall can be rotated to not obstruct the pipe circumference during installation
Solution Approach 2:
The sealing wall is designed to be movable/rotatable rather than fixed, allowing it to adapt its position based on operational requirements. When the calibrating element is in the maximum flow position, the sealing wall can be rotated to a position where it does not protrude, facilitating installation while maintaining the ability to seal when needed

AI summary
This device (D) for regulating the air flow in a pipe includes a flap (6) delimiting, relative to an inner surface (104) of a pipe (10) of the device (D), an air passage section (S), and an adjusting calibrating element (8) movable between a first position and a second position. The device includes a sealing wall (12), extending between the calibrating element and an inner surface (106) of the duct (10), suitable for preventing the passage of air from the side of the duct (10) opposite the air passage section (S). The sealing wall (12) is rotatable relative to the pipe (10) under the action of the movement of the calibrating element, and the calibrating element includes a front wall (86) perpendicular to the longitudinal axis (X-X′) of the duct (10) which, in the first position of the calibrating element, does not protrude past the circumference of the duct.
