A glue joint

Abstract

The utility model discloses a kind of glue injection joints, including glue joint inner core, glue joint outer sleeve, thin wall cover, glue cavity, glue injection hole and insert hose.Glue joint inner core is located in the inside of glue joint outer sleeve, thin wall cover is set in the inside of glue joint outer sleeve, and the middle part is formed glue cavity with the inner wall of sleeve.Glue injection hole that is communicated with glue cavity is equipped on glue joint outer sleeve, and insert hose is inserted between thin wall cover and glue joint inner core.The utility model uses water injection pre-pressing and glue injection curing two-stage sealing process, first inject high-pressure water into glue cavity through glue injection hole to make thin wall cover uniform deformation wrap insert hose, then discharge moisture and inject sealing glue to fix deformation state.Thin wall cover is fixed to the inner wall of sleeve, and multiple symmetrical glue injection holes ensure that glue injection is uniform.The joint structure is simple, reliable sealing, solve the problem that traditional glue injection joint is unevenly stressed, and the sealing effect is poor, especially suitable for oil pipeline, heat pipe and other medium-high pressure pipeline repair operation.
