It is made, but metallic plate is easily corroded, and tube sheet both sides are commonly present the larger temperature difference, metal tube sheets can be produced by temperature difference
Larger stress.
Utility model content
The purpose of this utility model is to provide a kind of tubular heat exchanger special tube sheet, and its is rational in infrastructure, easy to use,
With certain corrosion resistance, and metallic plate stress as caused by temperature difference can be reduced.
To achieve the above object, the technical solution of the utility model is a kind of special tube sheet of tubular heat exchanger of design, is wrapped
Include metallic plate；
Some metal sleeves are evenly equipped with the metallic plate；
Each metal sleeve is vertical with metallic plate, and each metal sleeve runs through metallic plate；
Each metal sleeve and metallic plate integrally connected, the inwall of each metal sleeve are provided with internal thread；
The metallic plate is furnished with a pair of thermal insulation boards, and this is parallel with metallic plate to thermal insulation board, and this is divided into gold to thermal insulation board
Belong to plate both sides；
Both side surface of above-mentioned a pair of the thermal insulation boards respectively with metallic plate bonds together, and this is covered each by gold to thermal insulation board
Belong to the both side surface of plate；
Each metal sleeve extends through above-mentioned a pair of thermal insulation boards；
Corrosion-resistant finishes has been respectively coated in the outer surface of above-mentioned a pair of thermal insulation boards.
Preferably, the outer surface of each metal sleeve is also coated with corrosion-resistant finishes.
The advantages of the utility model and beneficial effect are：There is provided a kind of tubular heat exchanger special tube sheet, its structure is closed
Reason, it is easy to use, there is certain corrosion resistance, and metallic plate stress as caused by temperature difference can be reduced.
Metal sleeve in the utility model is used to install heat exchanger tube, and the inwall of metal sleeve is provided with internal thread, Ke Yiyu
The externally threaded heat exchanger tube threaded connection of end band, it is easy for installation, after metal sleeve is threadedly coupled with heat exchanger tube, can further it enter
Row encapsulation process, encapsulation process have a variety of existing schemes, such as sealing welding.
Using metallic plate as tube sheet main body, metallic plate both side surface covering thermal insulation board, thermal insulation board can be reduced the utility model
Metallic plate stress as caused by temperature difference.
The outer surface of thermal insulation board is coated with corrosion-resistant finishes, can improve the corrosion resistance of tube sheet.
The outer surface of each metal sleeve is also coated with corrosion-resistant finishes, can further improve the corrosion resistance of tube sheet.
