Abstract
The utility model provides an integrated liquid bag, which can ensure efficiently the expansible joint quality of a thin tube sheet and a tube. The liquid bag can store high pressure water, can expand the tube, and can be connected with the tube sheet under the action of the high pressure; the fatigue load can be endured simultaneously with repeated use. The superhigh-strength integrated liquid bag comprises an annular sealed tube body, the inner diameter of the tube body is matched with the expansion rod of an expansion tube head, the outer diameter is formed an interstice fit with the inner diameter of the hole of the tube sheet, and the inner side wall of the tube body is provided with a liquid inlet.
Description
Technical field
The utility model relates to the Hydraulic expansion-jointing of tube bank heat transfer tube-to-tube sheet connection in a kind of shell-and-tube heat-exchanger rig that is widely used in industries such as oil, chemical industry, heat energy, boiler, especially used monoblock type liquid bag on the heavy caliber thin tubesheet Hydraulic expansion-jointing expand tube head of using for the boiler expand tube.
Background technology
At present, used superhigh intensity plastics liquid bag sleeve pipe on the Hydraulic expansion-jointing expand tube head, be applicable to that generally the expanded joint tube sheet is thick in the 30-500 millimeter, because sleeve pipe two ends short tube must have certain-length just can have the characteristics of self-energized seal, boiler's tube-plate is the heavy caliber thin tubesheet, normal tube plate thickness is the 10-30 millimeter, and liquid bag sleeve pipe manufacturer technology difficulty is very big, can not be suitable for.
Summary of the invention
The purpose of this utility model is the needs at the incompatibility thin tubesheet of existing liquid bag sleeve pipe existence, a kind of monoblock type liquid bag is provided, guaranteed the expanded joint quality of thin tubesheet and pipe effectively, this liquid bag can store water under high pressure and can be under high pressure be done bulging pipe and expanded joint tube sheet, simultaneously can bear fatigue load, use repeatedly.
The purpose of this utility model realizes by following measure:
Superhigh intensity monoblock type liquid bag is characterized in that it comprises the closed tube of an annular, and the internal diameter of body cooperates with the expander roll of expand tube head, its external diameter and tubesheet holes internal diameter matched in clearance, and the madial wall of body is provided with a liquid-inlet.
Advantage of the present utility model:
The utility model is designed for the Hydraulic expansion-jointing of thin tubesheet and pipe, for the expanded joint equally smoothly of thin tubesheet in the exchanging air.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Superhigh intensity monoblock type liquid bag of the present utility model as shown in Figure 1, comprises the closed tube of an annular, and the inner diameter d of body cooperates with the expander roll of expand tube head, its outer diameter D and tubesheet holes internal diameter matched in clearance, and the madial wall of body is provided with a liquid-inlet 1.
When the utility model used, on expander roll, the external diameter of liquid bag and the tubesheet holes internal diameter matched in clearance for the treatment of expanded joint were injected liquid with the expand tube rifle by expander roll with liquid bag sleeve, and after the liquid in the expand tube rifle injected the liquid bag, liquid bag pressurized expand tube was promptly realized Hydraulic expansion-jointing.
Claims (1)
1, superhigh intensity monoblock type liquid bag is characterized in that it comprises the closed tube of an annular, and the internal diameter of body cooperates with the expander roll of expand tube head, its external diameter and tubesheet holes internal diameter matched in clearance, and the madial wall of body is provided with a liquid-inlet.
