Inflatable structure for rectangular catalyst carrier and splicing method

Abstract

The invention discloses an inflatable structure for a rectangular catalyst carrier and a splicing method. The splicing method comprises the following steps: customizing two inflatable sealing strips in a mold form, namely a right-angle L-shaped sealing strip and a long-strip linear sealing strip, determining the splicing method of the two inflatable sealing strips according to the size of the required carrier, and connecting the sealing strips end to end after the splicing is completed. The hollow inflatable sealing ring is formed, and the air tap is installed at the position without the abutted seam. The inflatable structure can be used for catalyst carriers with rectangular sections, including square and rectangular catalyst carriers with the same or different length-width ratios, and the manufacturing cost of the inflatable structure for the rectangular catalyst carriers is reduced. Due to the existence of the positioning groove, when the inflatable structure of the rectangular catalyst carrier is matched with the clamp containing the positioning ring for use, the set shape of the inflatable sealing ring can be completely kept, and the required clamping or sealing function of the catalyst carrier is completed.

Description

technical field [0001] The invention relates to the technical field of sealing equipment, in particular to an inflatable structure and a splicing method for a rectangular catalyst carrier. Background technique [0002] The cross-sectional shape of the inflatable sealing ring is closed and hollow, forming a special elastic sealing structure in a hollow state as a whole. One or more air nozzles are connected outside a certain position of the inflatable sealing ring to inflate or deflate the inflatable sealing ring. After inflating the sealing ring, due to the expansion of the elastomer, the outer dimension of the sealing ring will increase to fill the gap between the sealing ring and the sealed structure. The inflatable sealing ring is made of high-elastic rubber, and the inflation pressure and the sealed rigid body structure reach a pressure balance, so that the expansion size of each position of the sealing ring can match the sealed structure, and finally the inflatable seal...

AI Technical Summary

Problems solved by technology

This method realizes the production of infinitely long inflatable sealing ring, ensures the uniform wall thickness of each part of the inflatable sealing ring, uniform vulcanization degree, speeds up the docking efficiency of the sealing ring, and avoids low product yield and poor quality due to docking errors caused by manual docking. The poor problem not only improves the production efficiency of the inflatable sealing ring, but also improves the quality and yield of the product, but the shape of the produced inflatable sealing ring is fixed and relatively single, and cannot be assembled and spliced ​​according to the needs of use
