Abstract
A sealing structure for a titanium steel or zirconium titanium steel composite board device lining is characterized in that a sealing structure at connection of a longitudinal welding seam and an annular welding seam comprises the annular welding seam (1) and the longitudinal welding seam (2). Detecting holes (3) are arranged in the longitudinal welding seam (2). An annular filler strip is disposed in the annular welding seam (1) in a spot welding manner. A longitudinal filler strip (5) and a longitudinal filler block (6) are disposed in the longitudinal welding seam (2). A gap (7) is reserved between the longitudinal filler strip (5) and the longitudinal filler block (6). Coating metal stickers (8) are welded on the annular welding seam (1) and the longitudinal welding seam (2) in a sealed manner. A support block (9) is filled on the upper portion of the gap (7). A cover plate (10) covering the coating metal stickers (8) on the annular welding seam (1) and the longitudinal welding seam (2) is welded on the support block (9) in a sealed manner. Leaking liquid from the longitudinal welding seam is prevented from entering the annular welding seam, leaking liquid from the annular welding seam is prevented from entering the longitudinal welding seam, and leakage can be detected in corresponding detecting holes (3) conveniently and timely. In addition, the sealing structure is capable of prolonging service lives of devices and improving detecting and maintenance efficiency.
Description
Technical field
the present invention relates to a kind of connection hermetically-sealed construction of composite cylindrical shell, especially can find in time that breakthrough and breakthrough can not have influence on the titanium steel of adjacent weld seam and adjacent leak detection point or a hermetically-sealed construction for titanium feature cylindrical shell, specifically a kind of titanium steel or zirconium equipment made of titanium-steel clad plate liner seal structure.
