Adjustable chemical material conveying pipeline connection structure

Abstract

This utility model discloses an adjustable chemical material conveying pipeline connection structure, including two sets of pipelines connected to each other by flanges. Each pipeline has a connecting ring I and a connecting ring II fitted on its outer wall, both of which are semi-circular. A sealing gasket is fixedly connected within the flange groove. This utility model utilizes an adjusting mechanism composed of a double-threaded rod, a limiting rod, and a slider, as well as a locking mechanism composed of a locking plate and a spring. During adjustment, the double-threaded rod drives the slider to slide synchronously in opposite directions, while the limiting rod prevents jamming and ensures adjustment accuracy. During locking, the spring drives the locking plate protrusion to engage with the rotating block groove to prevent loosening. Furthermore, the PTFE coating of the locking plate and the galvanized passivation treatment of the spring enhance corrosion resistance. This effectively solves the defects of traditional adjusting structures, such as transmission jamming, low adjustment accuracy, easy loosening of the lock, and easy corrosion of components, ensuring the sealing stability and long-term structural reliability of the conveying of hazardous chemical media.
