Vent Control Valve Annular Ridge Seal Line

The patent introduces an annular ridge part that creates a line contact geometry instead of a plane contact. The ridge part forms a curved or angled surface that concentrates the sealing force along a specific annular seal line, transforming the contact from a broad plane to a focused line with enhanced pressure distribution. This curvature-based approach prevents gas or liquid leakage by creating a more effective seal interface.

The patent applies local quality by creating a specific annular ridge part with distinct geometric features at the sealing interface. Instead of relying on the entire contact surface, the ridge part concentrates sealing functionality in a localized annular region. This localized enhancement of seal quality at the ridge line ensures reliable sealing performance while maintaining the overall structure.

The patent changes the geometric parameters of the contact interface by introducing the annular ridge part. This structural modification transforms the pressure distribution from a uniform broad-area contact to a concentrated line contact along the annular seal line. The parameter change in contact geometry maintains sufficient holding force while dramatically improving seal performance through localized pressure concentration.

The annular ridge part creates a curved or angled contact surface that concentrates force along a specific path. This curvature-based design transforms the force distribution, maintaining the holding force necessary to secure the seal component while preventing leakage by focusing the sealing pressure at the annular seal line rather than dispersing it over a large area.
