AI Technical Summary

Technical Problem

Existing push-fit connectors face issues with complex production of leakage paths, flexible handling, and potential damage to the system O-ring during reconnection under pressure, leading to unreliable sealing and reconnection.

Method used

A push-fit connection design featuring a plug-in part with a plug pin and receiving element, incorporating a sealing element with a radially extending leakage path on the pressure-reduced side, allowing pressurized fluid to escape and maintain the sealing element's position during reconnection.

Benefits of technology

Ensures reliable reconnection under pressure by preventing displacement of the sealing element and ensuring long-term functionality without complex production or damage, facilitating easy replacement of the leakage means.

Abstract

A push-fit connection for pipelines, comprising a plug-in part (14) and a receiving element (17) that can be connected and disconnected together, wherein the plug-in part (14) has a plug-in pin (11) at a first end that can be inserted into a receiving bore (16) of the receiving element (17) and a connection end (15) at a second end with which the plug-in part (14) can be connected to a pipe, with retaining elements (18) that hold the plug-in part (14) in a first locking position and, after the plug-in part (14) has been inserted further into the receiving bore (16), in a second locking position, and with a sealing element (19) located in a groove (10) on the plug-in pin (11), characterized in that a leakage means (1) is located in the groove (10) on a side of the sealing element (19) facing away from the pressure, which comprises at least one radially extending leakage path (3).
