Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, for the utility model discloses a flange, including ring flange 1, ring flange 1 center is equipped with the first material hole 11 of circular shape that supplies the material to pass through, is equipped with the through-hole 12 that supplies the bolt to pass on ring flange 1 around first material hole 11.

In order to enable the flange to be more conveniently recycled, one side of the flange plate 1 is provided with the three-jaw chuck 2, one side face, deviating from the clamping jaws of the three-jaw chuck 2, of the three-jaw chuck 2 is fixedly connected with the flange plate 1, the three-jaw chuck 2 is arranged on one side, facing the first material space, of the through hole 12, and the disc of the three-jaw chuck 2 is provided with the second material hole 21.

The inner diameter of the second material hole 21 is larger than the inner diameter of the first material hole 11. Can pass the jack catch of three-jaw chuck 2 with the flange dish 1 towards one side of three-jaw chuck 2 and support tightly with the one end of the internal diameter pipeline that the external diameter is greater than first material hole 11, support tightly through three-jaw chuck 2, make the pipeline of different external diameters of flange joinable.

In order to improve the sealing performance of the flange, one side of the flange plate 1 facing the three-jaw chuck 2 is provided with an annular rubber gasket 22, the outer diameter of the annular rubber gasket 22 is larger than the inner diameter of the second material hole 21, so that the end face of the pipeline can be in contact with the sealing gasket 4, and the inner diameter of the annular rubber gasket 22 and the inner diameter of the first material hole 11 cause no influence on the passing of the materials. One side of the flange plate 1, which is far away from the three-jaw chuck 2, is provided with a sealing gasket 4, and the sealing gasket 4 is connected with the flange plate 1, which is arranged at one side of the through hole 12, which faces the first material hole 11. The sealing between the two flanges 1 can be improved when connecting the two pipes.

In order to reduce the time required for aligning the through-holes 12 of the two flanges 1 when connecting pipes. The through holes 12 on the flange plate 1 are uniformly distributed on the periphery of the first material holes 11 in a circular shape; through-hole 12 is equipped with at least evenly distributed's two sets ofly, in this embodiment, is equipped with three group's through-holes 12, and every through-hole 12 of group includes two through-holes 12 about the relative setting in 11 centre of a circle of first material hole, and one side that arbitrary through-hole 12 of every through-hole 12 deviates from three-jaw chuck 2 is equipped with the sliding sleeve 3 with the coaxial setting of through-hole 12, and one side that another through-hole 12 of every through-hole 12 deviates from three-jaw chuck 2 is equipped with the annular 31 with the coaxial setting of through-hole 12, and the size shape of annular 31. The sliding sleeve 3 is far away from the fillet of the outer wall of one end of the flange plate 1.

The inner wall of the sliding sleeve 3 is flush with the inner wall of the through hole 12. The bolt can smoothly pass through the through hole 12, and the time for passing through the bolt can be reduced.

In order to reduce the processing difficulty of the flange plate 1, the section of the outer wall of the sliding sleeve 3, which is perpendicular to the axial direction of the sliding sleeve 3, is circular.

The implementation principle of the embodiment is as follows: when the inner diameter of the pipeline is not larger than that of the first material hole 11, one end of the pipeline sequentially penetrates through the second material hole 21 and the first material hole 11, the end face of the pipeline is flush with one side face, away from the flange plate 1, of the sealing gasket 4, the three-jaw chuck 2 is adjusted to enable clamping jaws of the three-jaw chuck 2 to be tightly abutted against the pipeline, and therefore the pipeline is connected with the flange plate 1; when the inner diameter of the pipeline is larger than that of the first material hole 11, one end of the pipeline penetrates through the clamping jaws of the three-jaw chuck 2 to be tightly abutted to the annular rubber pad 22, and then the three-jaw chuck 2 is adjusted to enable the clamping jaws of the three-jaw chuck 2 to be tightly abutted to the side wall of the pipeline, so that the pipeline is connected with the flange. When the pipeline is damaged, the clamping jaws on the three-jaw chuck 2 are adjusted to separate the clamping jaws from the pipeline, the pipeline can be separated from the flange, and the flange which is detached can be reused.
