AI Technical Summary

Technical Problem

Existing three-clamp connection devices take a long time to close and open, making them particularly difficult to operate when cleaning and handling toxic substances, and the use of secondary interfaces increases operational complexity.

Method used

A connection device is designed, including a support ring and a locking device. The combination of the support ring and the locking device allows for easy connection and disconnection of pipe ends. The locking body is adjustable between open and closed positions, providing an axial closing force for quick connection and disconnection.

Benefits of technology

It significantly reduces the time spent connecting and disconnecting pipe ends, simplifies the operation process, and is particularly suitable for chemical and biotechnology applications, reducing the risk of toxic substance leaks.

Abstract

The invention relates to a connection device (10) for connecting a first pipe end (12) with a second pipe end (14), the first pipe end (12) having a flange-like radial first widening (16) with a first end face (18) and a first back face (20), and the second pipe end (14) having a plurality of flange-like radial second widenings (22) with a second end face (24) and a second back face (26), respectively, the second widenings (22) being separated from one another by means of interruption sections (84), and the connection device (10) comprising a connection ring (74) with a first closure face (76) and a plurality of second closure faces (78), the second closure faces (78) being separated from one another by means of passage sections (80), the first closure face (76) being placeable in abutment with the first back face (20), and the second closure faces (78) being placeable in abutment with the second back faces (26) by the second widenings (22) being guided through the passage sections (80) in an axial movement and then performing a relative rotational movement between the connection ring (74) and the first pipe end (12) and / or a relative rotational movement between the connection ring (74) and the second pipe end (14). Furthermore, the invention relates to a method and a connection assembly (85) for connecting a first pipe end (12) with a second pipe end (14) by means of such a connection device (10).
