Abstract
The utility model relates to a connecting structure of a U-shaped tube heat exchanger tube plate and equipment flanges, and belongs to the technical field of heat exchange equipment. The connecting structure comprises the equipment flanges and the tube plate (2.1). The equipment flanges comprise the tube box flange (1) and the shell flange (3). The external diameter of the tube plate (2.1) is increased to be the same as the external diameter of the equipment flanges, a threaded through hole (2.2) is machined in the tube plate (2.1), and through the threaded through hole (2.2) in the tube plate (2.1), the tube box flange (1), the tube plate (2.1) and the shell flange (3) are fixedly connected through a full-thread stud (4.2) and a nut (5). By the adoption of the connecting structure, in the manufacturing process of equipment, material cost can be reduced, a test tool can be omitted, and the test working procedures can be optimized.
Description
Technical field
The utility model relates to a kind of U-shaped heat exchange of heat pipe, especially relates to a kind of U-shaped heat exchange of heat pipe tube sheet and vessel flange syndeton.Belong to heat transmission equipment technical field.
Background technology
The U-shaped heat exchange of heat pipe structure that conventional design is manufactured is referring to Fig. 1, and channel flange, tube sheet, shell flange syndeton are referring to Fig. 2.U-shaped heat exchange of heat pipe by Fig. 1 structure can present following problem:
1, sometimes due to pipe, shell side pressure reduction is larger, causes the side flange thickness that pressure is low to be controlled by the high side of pressure, the flange thickness of low-pressure side is increased, thereby improves material cost.
2, shell side carries out pressure test and checks tube head simultaneously, must have test pressure ring (referring to Fig. 3).
3, dismounting one side, opposite side is also opened simultaneously, and opposite side also needs to carry out pressure test.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of in equipment Manufacture Process, can save material cost, saves test tool, U-shaped heat exchange of heat pipe tube sheet and the vessel flange syndeton of Optimum Experiment operation.
The purpose of this utility model is achieved in that a kind of U-shaped heat exchange of heat pipe tube sheet and vessel flange syndeton, comprise vessel flange and tube sheet, vessel flange comprises channel flange and shell flange, it is characterized in that: the external diameter of tube sheet is increased to consistent with vessel flange external diameter, and on tube sheet, be processed with tapped through hole, by the tapped through hole on tube sheet, with full thread double-screw bolt and nut, channel flange, tube sheet and shell flange are connected and fixed.
The beneficial effects of the utility model are:
1, the vessel flange of pipe, shell side can calculate respectively, thus the flange thickness of attenuate low-pressure side, thus reduce material cost.
When 2, shell side carries out pressure test (inspection tube head), remove test pressure ring (referring to Fig. 6) from.
3, dismounting one side, opposite side still keeps sealing, removes the operation that opposite side is done pressure test from.
