Pipeline 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 calibration elements that make installation difficult, as they need to cover the entire duct section for maximum flow adjustment, leading to installation complications.
Innovation Solution
A device with a rotatable sealing wall and an adjustable calibration element that moves perpendicular to the flap's axis of rotation, preventing air passage from the opposite side without protruding, allowing for easy installation within a pipe by maintaining a sealing wall that does not extend beyond the duct's circumference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the calibration element is placed in a more advanced position to adjust air flow, then the flow adjustment capability is improved, but the front face protrudes beyond the device circumference making installation difficult
Solution Approach 1:
The sealing function is transitioned from a static front face to a rotatable sealing wall that moves in a different dimensional space (rotational movement perpendicular to the flow direction). This allows the calibration element to extend forward for flow adjustment while the sealing wall rotates to seal the duct perimeter, solving the installation problem without sacrificing flow control capability
Solution Approach 2:
The sealing wall is made dynamic by enabling it to rotate relative to the duct. This rotational movement allows the sealing surface to adapt its position - sealing the perimeter when needed for installation and moving aside when the calibration element needs to extend for flow adjustment, thus resolving the contradiction between protrusion and installation ease

AI summary
This device (D) for regulating the flow of air in a pipe comprises a flap (6) delimiting, with respect to an internal surface (104) of a duct (10) of the device (D), a section (S) air passage, and an adjustable calibration element (8) movably mounted between a first position and a second position. The device (D) comprises a sealing wall (12), extending between the calibration element (8) and an internal surface (106) of the duct (10), adapted to prevent 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 duct (10) under the action of the movement of the calibration element (8), and the calibration element (8) comprises a front wall (86 ) perpendicular to the longitudinal axis (X-X') of the duct (10) which, in the first position of the calibration element (8), does not protrude beyond the circumference of the device.
