FAST OPENING AND CLOSING ACCESS DOOR FOR PIPES AND CONTAINERS

摘要

The invention concerns a fast opening and closing access door for pipes and containers. Said door consists of a flange (1) and a plug (2) comprising a sealing autoclave joint (4) arranged in a circular joint plane inclined relative to the system axis, linking a joint surface of the plug including a groove itself inclined designed to receive said autoclave joint and a locking closure system (5) by displacement in a plane perpendicular to the axis of the access door such that the thrust resulting from the fluid pressure is exerted parallel to said axis. The invention generally concerns the field of pressurised containers such as filters, and all types of pipe systems, in particular extended pipe systems with high flow rate often called pipelines, whether for transporting liquids, gases or materials in powder form.
