Abstract
A welded structure for cylindrical shell, lining and expansion joint, comprises lower cylinder body, lining, and upper cylinder is welded with expansion joint between lower cylinder body and upper cylinder, and described expansion joint lower extreme point is welded with lining, does not weld that to be convenient to expansion joint flexible between expansion joint upper end and lining; Described lower cylinder body, expansion joint and upper cylinder weld the inside are provided with straight flange B, straight flange B=0.5 ~ 2mm; Outside is provided with groove, and the angle of groove and substantially horizontal is 28 ~ 32 °; Between expansion joint and lower cylinder body and upper cylinder, be provided with spacing A, spacing A=0.5 ~ 2mm.The utility model is rational in infrastructure, and long service life is safe and reliable.
Description
Technical field
The utility model relates to heat-exchange apparatus, specially refers to the welded structure of a kind of condenser upper cylinder, lining and expansion joint.
Background technique
Expansion joint is also slip joint traditionally, belong to a kind of compensating element, arrange in the middle of the pipeline often, can compensate the amount of expanding with heat and contract with cold in pipe lengths and keep the device of pipeline sealing, expansion joint is mainly used in compensating the dilatation that pipeline produces because of temperature variation, also waits because installing to adjust the length compensation needing for pipeline.On existing condenser, expansion joint is fragile.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, long service life, the welded structure of safe and reliable cylindrical shell, lining and expansion joint.
The purpose of this utility model is achieved in that the welded structure of a kind of cylindrical shell, lining and expansion joint, comprise lower cylinder body, lining, upper cylinder, between lower cylinder body and upper cylinder, be welded with expansion joint, it is characterized in that: described expansion joint lower extreme point is welded with lining, between expansion joint upper end and lining, do not weld that to be convenient to expansion joint flexible; Described lower cylinder body, expansion joint and upper cylinder weld the inside are provided with straight flange B, straight flange B=0.5 ~ 2mm; Outside is provided with groove, and the angle of groove and substantially horizontal is 28 ~ 32 °; Between expansion joint and lower cylinder body and upper cylinder, be provided with spacing A, spacing A=0.5 ~ 2mm.
Between expansion joint described in the utility model upper end and lining, be provided with 10mm spacing.
The utility model is rational in infrastructure, and long service life is safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, lower cylinder body, 2, lining, 3. spacing A, 4, straight flange B, 5, upper cylinder, 6, groove, 7, expansion joint.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, the welded structure of a kind of cylindrical shell, lining and expansion joint, comprise lower cylinder body 1, lining 2, upper cylinder 5, between lower cylinder body 1 and upper cylinder 5, be welded with expansion joint 7, it is characterized in that: described expansion joint 7 lower extreme points are welded with lining 2, between expansion joint 7 upper ends and lining 2, do not weld that to be convenient to expansion joint 1 flexible; Described lower cylinder body 1, expansion joint 7 and upper cylinder 5 weld the insides are provided with straight flange B4, straight flange B4=0.5 ~ 2mm; Outside is provided with groove 6, and groove 6 is 28 ~ 32 ° with the angle of substantially horizontal; Between expansion joint 7 and lower cylinder body 1 and upper cylinder 5, be provided with spacing A3, spacing A3=0.5 ~ 2mm.Between described expansion joint 7 upper ends and lining 2, be provided with 10mm spacing.When concrete enforcement, at the swollen joint expansion place welding lining of cooling liquid inlet end, make lining play water conservancy diversion to cooling liquid, do not affect again expansion joint simultaneously and expand, the working life of having improved expansion joint.
