Description

Technical Field

[0001] The invention relates to the technical field of flange rings, and more specifically to a plate-type butt-welding flange. Background Art

[0002] A plate flange is a flange that is connected to a container or pipe by a fillet weld. It is a flange that is fixed by the contact gap at the welding connection position when the flange is connected to the pipe. Flat welding flanges have the advantages of low cost, simple structure, and less material, and are widely used in connections between pipes.

[0003] During the welding process of the existing flat welding flange, the flange needs to be put on the pipe first and then welded at the connection position. Since the flange and the pipe are not fixed in advance, if there is a slight offset during welding, the flange will not be able to be connected to the matching flange after welding. In addition, only corner welding is used, and the connection area between the welding position and the method is not very large. In the subsequent long-term use, the problem of desoldering is prone to occur.

[0004] Therefore, it is necessary to provide a plate-type butt-welding flange to solve the above problems. Utility Model Content

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a plate-type butt-welding flange.

[0007] Furthermore, a pipeline is arranged on one side of the flange structure, and a plurality of welding grooves are opened on the inner wall of the embedded ring.

[0008] Furthermore, a flange matching with the flange structure is arranged on the other side of the flange structure, and a matching ring matching with the size and shape of the sealing groove is arranged on the flange.

[0009] Furthermore, the embedded gasket fits the outer wall of the pipeline.

[0010] The outer wall of the connecting ring is provided with a plurality of through holes, and matching bolts for connection are arranged in the through holes.

[0023] like Figure 1-3As shown, the present application provides a plate-type butt-welding flange, including a flange structure 1, the flange structure 1 includes a connecting ring 101, one side of the connecting ring 101 is provided with an integrally formed embedded ring 104, the outer wall of the embedded ring 104 is provided with four positioning bolts 107 penetrating the embedded ring 104, one side of the embedded ring 104 is provided with an embedded gasket 105, one side of the connecting ring 101 is provided with a sealing groove 102, and a sealing gasket 103 is provided inside the sealing groove 102.

[0024] A pipeline 2 is arranged on one side of the flange structure 1 , and a plurality of welding grooves 106 are formed on the inner wall of the embedded ring 104 .

[0025] A flange matching the flange structure 1 is disposed on the other side of the flange structure 1 , and a matching ring 108 matching the size and shape of the sealing groove 102 is disposed on the flange.

[0026] The embedded gasket 105 is in contact with the outer wall of the pipe 2 .

[0027] The outer wall of the connecting ring 101 is provided with a plurality of through holes, and matching bolts for connection are arranged in the through holes.

[0028] The diameter of the pipe 2 matches the inner circular diameter of the embedded ring 104 .

[0029] The middle part of the embedded ring 104 and the base of the connecting ring 101 are both provided with flow openings with the same diameter.

[0030] Working principle:

[0031] Before using the device, first check the various components of the device to ensure that the various components of the device cooperate properly and ensure that the device can work normally.

[0032] When the device needs to be used, first, its flange is matched with the pipeline so that the pipeline wall of the pipeline 2 contacts the embedded gasket 105. The user pushes the flange structure 1 so that the flange structure 1 is in full contact with the pipeline 2. The user locks the four positioning bolts 107 so that the positioning bolts 107 lock the pipeline. When it is locked, when the user needs to weld, the user first welds the device through a plurality of welding grooves 106 so that the embedded ring 104 and the pipeline 2 are connected first. When the welding grooves 106 are all welded and there is no gap between the sealing groove 102 and the pipeline 2, the user performs fillet welding along one side of the embedded ring 104 and the outer wall of the sealing groove 102 so that the device is connected to the pipeline 2 again. When it is welded, the user can weld the four positioning bolts 107 to the embedded ring 104 again to achieve triple welding positioning.

[0033] When the two flange structures 1 are spliced, the mating ring 108 of one connecting ring 101 is matched with the sealing groove 102 opened on the other connecting ring 101, and the two flange structures 1 are locked by the mating bolts connected externally, and the mating ring 108 squeezes the sealing gasket 103 to achieve sealing.

[0034] By providing this device, the connection firmness between the flat-welded flange and the pipeline can be further improved, the welding points between the flange and the pipeline can be increased, the failure of the welding points after long-term use of the flange and the pipeline can be avoided, and the problems of air leakage and water leakage at the welding points can be avoided.
