AI Technical Summary

Technical Problem

The sealing performance of existing gas extraction pipeline testing interfaces is prone to wear and aging, leading to gas leakage. Moreover, the operation is cumbersome and cannot meet the needs of rapid and frequent testing.

Method used

The design of linking the movable sealing component and the triggering component enables the automatic opening and closing of the detection channel. Combined with the abutment seal between the sealing component and the installation interface, the elastic reset component provides pre-tightening force to ensure sealing performance and simplify the operation process.

Benefits of technology

It enables quick plugging and unplugging of the detection interface and automatic sealing, improving detection efficiency, ensuring reliable sealing performance, preventing gas leakage, and reducing maintenance costs.

Abstract

This utility model belongs to the mining field, specifically a quick-connect interface for gas drainage pipeline testing. It includes an installation interface, a testing interface, and a sealing cavity, all coaxially connected to form a testing channel. A movable part is positioned within the sealing cavity via a first rotating shaft, and a first elastic reset component causes the movable part to tend to rotate towards the testing channel. A trigger component is fixed to the movable part and extends at least partially into the testing channel. A sealing component is movably connected to the movable part and abuts against the installation interface to block the testing channel. When the testing element is inserted into the testing channel, it pushes against the trigger component, causing the movable part to rotate away from the testing channel, simultaneously disengaging the sealing component from the installation interface, thus opening the testing channel. This utility model has a reasonable structure, is easy to operate, and provides reliable sealing. It meets the requirements of coal mine gas drainage sites for a fast, safe, and durable testing interface and is suitable for connecting gas drainage pipelines to portable testing equipment.
