AI Technical Summary

Technical Problem

Existing deformation valves for liquid or paste products struggle with inconsistent sealing due to precise positioning requirements and low overpressure triggering, leading to potential bacterial contamination and operational failures, especially when dosing small amounts.

Method used

A deformation valve design featuring a chimney connected to a rigid rod with a sealing wall that undergoes radial deformation, allowing for a lower overpressure threshold and improved sealing by ensuring the valve closes independently of axial positioning, reducing bacterial contamination risks.

Benefits of technology

The valve achieves reliable sealing and reduced bacterial contamination by minimizing the overpressure required for opening, ensuring consistent closure and preventing back-contamination, even when dosing small quantities.

Abstract

The present proposes a distribution valve (10), comprising at least one channel (25) connecting an upstream end (11) of the valve to a product outlet orifice, consisting of a stem (20); an elastically deformable sealing valve (30), consisting of a chimney (31) surrounding the stem (20); a sealing wall (32); of an annular connection zone (33), the sealing wall (32) being pierced by the outlet orifice (12) formed in a movable sealing zone (322) between a closed position and an open position, characterized in that the chimney (31) comprises a fixing zone (312) located in its upstream part and ensuring the fixed connection with the rod (20), and an annular deformation zone (313) located in its downstream part connecting the fixing zone (312) and the downstream end (311) of the chimney (31); the deformation zone (313) being distant from the rod (20) in any plane P2 perpendicular to the flow axis (X);and the annular connection zone (33) is mobile in a radial direction oriented towards the rod (20).
