[0024] Please refer to Figures 1-4 , in the embodiment of the present invention, it includes a flange ring 1, an insertion pipe 2, a docking pipe 3, a sealing sleeve 4 and a collar 5;

[0025] One side of the flange ring 1 is welded with an insertion pipe 2, the side of the flange ring 1 away from the insertion pipe 2 is welded with a docking pipe 3, a collar 5 is sleeved outside the docking pipe 3, an external thread top ring 11 is welded on the side of the collar 5 close to the flange ring 1, a sealing sleeve 4 is welded on the side of the flange ring 1 located outside the docking pipe 3, and a sealing gasket 9 is glued inside the sealing sleeve 4.

[0026] Among them, bolt holes 7 are equidistantly penetrated on one side of the flange ring 1, and first clamping grooves 8 are opened at both ends on the outside of the flange ring 1. The opening of the bolt holes 7 facilitates personnel to fix the flange ring 1 on the glass-lined equipment with bolts, and the opening of the first clamping grooves 8 facilitates personnel to rotate the flange ring 1 with tools.

[0027] Among them, a sealing ring 6 is glued on the side of the flange ring 1 located outside the insertion pipe 2, and the sealing ring 6 seals between the flange ring 1 and the glass-lined equipment.

[0028] Among them, an internal thread groove 10 corresponding to the external thread top ring 11 is opened on the inner surface of the sealing sleeve 4, and the opening of the internal thread groove 10 facilitates the screwing of the external thread top ring 11.

[0029] Among them, second clamping grooves 12 are equidistantly opened on the outside of the collar 5, and the opening of the second clamping grooves 12 facilitates personnel to rotate the collar 5 with tools.

[0030] Among them, external thread teeth 13 are provided on the outside of both the insertion pipe 2 and the docking pipe 3. The setting of the external thread teeth 13 facilitates the screwing of the insertion pipe 2 into the glass lining and also facilitates the screwing of the pipeline outside the docking pipe 3.

[0031] The working principle of the utility model is as follows: The insertion pipe 2 is screwed onto the glass-lined equipment through the external screw teeth 13 on the outer side of the insertion pipe 2 until the flange ring 1 is tightly attached to one side of the glass-lined equipment. Then, bolts are used to fix the flange ring 1 to the flange ring 1 through the bolt holes 7, so that the device can be fixed to the flange ring 1. After the flange ring 1 is fixed, the sealing ring 6 seals between the flange ring 1 and the glass-lined equipment.
