Abstract
The invention relates to an expansion packer rubber barrel. The expansion packer rubber barrel comprises a rubber barrel body (1), metal connecting pipes (2) and annular rings (3), wherein the two ends of the rubber barrel body (1) are fixed to the metal connecting pipes (2) through heat vulcanization technology glue, the two ends of the rubber barrel body (1) are fastened through the annular rings (3), and carbon fiber cord fabric (4) is buried in the rubber barrel body (1). The carbon fiber cord fabric high in tensile strength is buried in the rubber barrel body and is very popular and catches close attention because of having the advantages of being soft in texture, resistant to corrosion, very thin in sheet material, high in tensile strength and the like. Compared with an existing method that steel wires are buried in the rubber barrel body, the bearing capacity and expansion amount of the rubber barrel are greatly improved, the service life of the rubber barrel at high temperature is greatly prolonged, the phenomenon that because the steel wires are high in to rigidity, the components are damaged easily is avoided, and the expansion packer rubber barrel is simple in machining technology and easy to popularize and apply.
