| titleOfInvention | Coupling device of spiral duct |
| abstract | The present invention relates to a spiral duct connecting device for connecting and installing a spiral duct (Spiral Duct) mainly made by winding a long iron plate spirally.n n n The connection of the spiral duct installed in a conventional ship is to insert a small diameter helical duct (1) to a large diameter helical duct (1) to be fixed with a screw (30) at regular intervals or to form a spiral flange (20) spiral duct ( 1) can be divided into bolts (3 ') and nuts (4') and fastened with N-shaped flanges (20) against each other by fixing them with bolts (3) and nuts (4).n n n In order to prevent corrosion of the screw 30 because the former is not firmly connected, cracks are generated at the end and water is introduced into the gap between the large and small spiral ducts 1 and 1 '. The problem is that the gap should be sealed with silicon (Silicon) with a lot of manpower and time.n n n The latter is to fix the N-shaped flange 20 to the helical duct (1) to be fixed by bolts (3 ') and nuts (4'), so that the structure is complicated and requires a lot of production costs, and its part is used to promote oxidation corrosion. The problem was to shorten the life.n n n The present invention forms a narrow engaging bending piece (1A) at the end of the helical duct (1) and the ring flange (2) by inserting a ring flange (2) in the helical duct (1) to solve the above problems When the flanges 2 are joined to each other with the bolts 3 and the nuts 4, the ring flanges 2 are caught by the bending bending pieces 1A so that the spiral ducts 1 can be firmly connected. The object is to provide a helical duct connection. |
