Abstract
The utility model provides an optimized structure for welding a boiler shell. The optimized structure comprises a cylindrical body. The cylindrical body is made by rolling up a steel plate. Two inclined surfaces are formed on both ends of the joint of the steel plate and a V-shaped groove is formed by the two inclined surfaces. According to this arrangement, welding can be done in the V-shaped groove to enable welding flux to flow into the V-shaped groove completely. Accordingly, defects as pseudo soldering and sealing off can be avoided, so that the safety can be improved by using the boiler.
Description
Technical field
The utility model belongs to boiler manufacturing technology field, is specifically related to a kind of welding for boiler barrel and optimizes structure.
Background technology
Boiler barrel is owing to wanting bearing certain pressure, conventionally all adopt the steel plate that monoblock is thicker roll and be welded, because steel plate is thicker, easily there is the weld defects such as rosin joint, sealing-off in piece when welding, bring potential safety hazard to follow-up use, be therefore necessary to improve.
Utility model content
The technical problem that the utility model solves: provide a kind of welding for boiler barrel to optimize structure, be all shaped with inclined-plane at the both ends of steel plate edge joint position, two inclined-planes form V-type groove, then welding in V-type notch.
The technical solution adopted in the utility model: the welding for boiler barrel is optimized structure, and has cylindrical shell, described cylindrical shell is rolled by steel plate, and the both ends of the edge joint position of described steel plate are all shaped with inclined-plane, and two inclined-planes form V-type groove.
Further, the notch of described V-type groove is 60 ° of-80 ° of angles.
The utility model is compared with prior art shaped with inclined-plane by the both ends at steel plate edge joint position, two inclined-planes form V-type groove, and during welding, in V-type groove, scolder can fully flow in V-type notch, effectively avoid the defects such as rosin joint, sealing-off, improve the safety in utilization of boiler.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the I portion enlarged drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.
Welding for boiler barrel is optimized structure, and has cylindrical shell 1, and described cylindrical shell 1 is rolled by steel plate 2, and the two ends at piece 3 places of described steel plate 2 are all shaped with inclined-plane, 4, two, inclined-plane 4 and form V-type groove 5, and preferably the notch of V-type groove 5 is 60 ° of-80 ° of angles.
The utility model is all made a little inclined-plane 4 by the both ends at piece 3 places at steel plate 2, two inclined-planes form V-type groove, and during welding, in V-type groove, scolder can fully flow in V-type notch, effectively avoid the defects such as rosin joint, sealing-off, improve the safety in utilization of boiler.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
Claims (2)
1. for the welding of boiler barrel, optimize structure, there is cylindrical shell (1), described cylindrical shell (1) is rolled by steel plate (2), it is characterized in that: the both ends that the piece (3) of described steel plate (2) is located are all shaped with inclined-plane (4), and two inclined-planes (4) form V-type groove (5).
2. the welding for boiler barrel according to claim 1 is optimized structure, and it is characterized in that: the notch of described V-type groove (5) is 60 ° of-80 ° of angles.
