Description
Technical Field
The utility model relates to a flange technical field especially relates to a novel loose flange.
Background
The loose flange is one loose flange around the container or pipeline, and has the advantages of no additional moment produced to the container or pipeline during deformation, easy manufacture, capacity of being made of different material from that of the container or pipeline and saving in noble metal. The existing lap joint flange is a complete ring, and when the lap joint flange is used, one end with a smaller size, namely one end without a bulge on a pipeline, is sleeved outside the pipeline, otherwise, the lap joint flange cannot be sleeved.
Disclosure of Invention
An object of the utility model is to prior art not enough, and provide a novel lap joint flange, it can be convenient with two parted flange cover halves on the pipeline, the outer loop size is great, can directly embolia, and improved the intensity of flange after inner ring and the outer loop combination.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel lap joint flange, its includes outer loop, inner ring, the inner ring is including can welding into two circular shape semicircular and divide half flanges, the inner ring is provided with the flange hole, the excircle of inner ring is provided with the boss that outwards stretches out, the interior circle of outer loop be provided with the recess that the boss corresponds, the outer loop cup joint in the outside of inner ring.
Preferably, the outer ring is an interference fit with the inner ring.
Preferably, the thicknesses of the outer ring and the inner ring are the same.
Preferably, the boss is positioned on one side of the inner ring close to the joint
The utility model has the advantages that: the utility model provides a novel lap joint flange, its includes outer loop, inner ring, the inner ring is including can welding into two circular shape semicircular divide half flanges, the inner ring is provided with the flange hole, the excircle of inner ring is provided with the boss that outwards stretches out, the interior circle of outer loop be provided with the recess that the boss corresponds, the outer loop cup joint in the inner ring outside, the utility model discloses structure science, can be convenient with two detached divide half flanges cover on the pipeline, the outer ring size is great, can directly embolia, and the intensity of flange has been improved after inner ring and the outer loop combination.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1 to 4, the novel lap joint flange of the present embodiment includes an outer ring 1 and an inner ring 2, the inner ring 2 includes two semicircular half flanges 21 that can be welded into a circular shape, the inner ring 2 is provided with a flange hole 22, an outer circle of the inner ring 2 is provided with a boss 23 extending outward, an inner circle of the outer ring 1 is provided with a groove 11 corresponding to the boss 23, and the outer ring 1 is sleeved on an outer side of the inner ring 2. When the pump is used, the outer ring 1 is firstly sleeved on a pump body or a pipeline, then the two half flanges 21 are spliced and sleeved on the pump body or the pipeline, then the inner ring 2 is matched with the outer ring 1, namely the lug boss 23 is embedded into the groove 11, then the welding seam shown in figure 2 is used for welding the two independent half flanges 21 into the integrated inner ring 2. The structure has few welding points, can conveniently sleeve the flange on a pipeline, also increases the integral flange width of the flange, and improves the connection strength of the flange.
Further, the outer ring 1 is in interference fit with the inner ring 2.
Further, the thickness of the outer ring 1 and the inner ring 2 is the same.
Further, the boss 23 is located on the side of the inner ring 2 close to the joint.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
