Abstract
The invention discloses a tube sheet plane deformation prevention device. The tube sheet plane deformation prevention device is characterized by comprising a flat cover and a plurality of pull rods, wherein a cross-shaped rib is arranged on one surface of the flat cover; each pull rod is provided with a spacer tube; and a plurality of fixing holes matched with a tube sheet are formed in the flat cover. The tube sheet plane deformation prevention device has the advantages of simple structure, convenience in use and good deformation effect.
Description
Technical field
The present invention relates to a kind of anti-deformation device, relate in particular to a kind of tube sheet plane anti-deformation device.
Background technology
Owing to make tube sheet generation because of welding stress in welding process deform near factors such as tube sheet place large openings on the tube sheet in the fixed tube-sheet exchanger and the welding of heat exchanger tube joint, the shell-side cylinder, influence the sealing of its sealing surface, so need to adopt anti-deformation tool to prevent or reduce the distortion of tube sheet sealing surface.
Summary of the invention
The purpose of this invention is to provide a kind of tube sheet plane anti-deformation device.
The technical solution used in the present invention is:
Tube sheet plane anti-deformation device comprises flat cover and some pull bars, and the one side of described flat cover is provided with the cross muscle, is provided with distance sink tube on the every pull bar, and described flat cover is provided with a plurality of fixing holes that match with tube sheet.
The thickness of described flat cover is greater than the thickness of tube sheet.
Advantage of the present invention is: simple in structure, easy to use, anti-deformation is effective.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the side view of Fig. 1.
Wherein: 1, cylindrical shell, 2, tube sheet, 3, flat cover, 4, the cross muscle, 5, fixing hole, 6, deflection plate, 7, distance sink tube, 8, pull bar.
The specific embodiment
In order to deepen the understanding of the present invention, be described in further detail of the present invention below in conjunction with embodiment and accompanying drawing, this embodiment only is used to explain of the present invention, does not constitute the qualification to protection scope of the present invention.
As depicted in figs. 1 and 2, tube sheet of the present invention plane anti-deformation device comprises flat cover 3 and some pull bars 8, and the one side of flat cover 3 is provided with cross muscle 4, be provided with distance sink tube 7 on the every pull bar 8, flat cover 3 is provided with a plurality of fixing holes 5 that match with tube sheet 2.
Advantage of the present invention is: simple in structure, easy to use, anti-deformation is effective.
During use, by pull bar 8 and distance sink tube 7 tube sheet 2 is fixed on the deflection plate 6 in the cylindrical shell 1, by fixing hole 5 tube sheet 2 and flat cover 3 are installed together then, flat cover 3 thickness are greater than the thickness of tube sheet 2, weld after fixing, treat that tube sheet 2 is welded on the cylindrical shell 1 fully after, can be down with flat cover 3 and pull bar 8 dismountings, whole process is convenient and swift, and anti-deformation is effective.
