Example (b):
as shown in fig. 1-3, the invention provides a large arc-shaped water chamber of a condenser, which comprises a connecting pipe 1 and connecting flanges arranged at two ends of the connecting pipe 1. The connection pipe 1 is used for flowing water. Two connecting flanges at two ends of the connecting pipe 1 are respectively connected to the condenser and the pipeline. So that circulating water flows between the condenser and the pipe through the connection pipe 1. The connection flange comprises a flange ring and a connection ring 32. The flange ring is arranged on one side of the flange ring away from the flange surface in a protruding mode. The end of the connection ring 32 remote from the flange ring is connected to the connection pipe 1. The flange ring of the circular flange 3 and the flange ring of the rectangular flange 2 are both provided with a plurality of connecting holes. When in connection, the connecting flange can be connected with a pipeline or a condenser through bolts.
The utility model discloses a when the large-scale arc hydroecium of condenser was made, earlier with two flange and 1 processing of connecting pipe complete, assemble the welding at last. During assembly welding, the two ends of the connecting pipe 1 are respectively welded to the connecting rings 32 of the two connecting flanges. Since the connection ring 32 has a certain length, its end is spaced apart from the flange ring. During welding, the distance can well avoid thermal deformation of the flange ring caused by high welding temperature. Thereby ensuring the precision of the connecting flanges at the two ends. Meanwhile, the structure enables all parts of the water chamber to be firstly combined into assemblies and processed, and finally, a plurality of assemblies are assembled and welded. Therefore, each part of the water chamber is prevented from being completely assembled and welded and then subjected to finish machining, and further the cost and safety risk for the large-scale object to be transferred are reduced. Thereby improving the production efficiency and being beneficial to the production organization.
In this embodiment, the connecting flange comprises a rectangular flange 2. The one end of condenser is connected to rectangle flange 2, and its shape is the same with the shape of the side of condenser to rectangle flange 2 can be fine laminating and be connected in the side of condenser. The rectangular flange 2 comprises four corner pieces 21 and two pairs of side pieces 22. The corner piece 21 is "L" shaped. Four corner pieces 21 are provided at four corners. The two ends of the corner pieces 21 are each connected to a side piece 22 and the two side pieces 22 in pairs are arranged opposite each other, so that the four corner pieces 21 and the two pairs of side pieces 22 enclose a rectangular flange ring. After the four corner pieces 21 and the two pairs of side pieces 22 are enclosed into a rectangular flange ring, all the components are welded together. The two side members 22 of each pair are of the same length, and the length of the side members 22 of different pairs may be the same or different, as desired. If the flange rings are the same, the flange rings are square; if different, the flange ring is rectangular.
The flange ring is manufactured by splicing a plurality of components, and the components can be obtained by blanking from the same steel plate during blanking, so that the blanking of the flange ring is completed. Annular flange ring need not directly cut off from same steel sheet for the utilization of steel sheet is more abundant, avoids directly cutting out the flange ring and leads to the inconvenient utilization of steel sheet residual material.
In this embodiment, the connection ring 32 includes two pairs of connection plates 23. The two pairs of connecting plates 23 are enclosed to form a rectangular tube shape. Similarly, the connecting ring 32 can also utilize the steel plate to the maximum by splicing the connecting plates 23, and waste of the steel plate is avoided.
In this embodiment, the connection flange further comprises a circular flange 3. The circular flange 3 is used for connecting the pipes 1. The circular flange 3 comprises a plurality of circular arc plates 31 in the shape of circular arcs. The arc plates 31 are spliced into a circle.
In the present embodiment, the connection pipe 1 includes a transition section 11 and a connection section 12 connected to each other. The transition section 11 is connected to the rectangular flange 2. The connecting section 12 is connected to the circular flange 3. The inner diameter of the transition section 11 is gradually reduced from one end of the rectangular flange 2 to one end of the connecting section 12. The transition section 11 has a decreasing inner diameter, which is used for the difference in inner diameter between the transition connection section 12 and the ring of the rectangular flange 2.
In this embodiment, the transition section 11 includes 4 arc plates; the 4 arc plates are spliced into the transition section 11. The utilization rate of the material is improved.
In this embodiment, the flange ring of the circular flange 3 and the flange ring of the rectangular flange 2 are both provided with a plurality of connecting holes.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
