Detailed Description
To make the above objects, features and advantages of the present utility model more comprehensible, the following embodiments are presented in order to illustrate the present utility model, but the present utility model can be practiced in other manners different from those described herein, and thus the present utility model is not limited to the specific embodiments disclosed below.
In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front," "rear," "head," "tail," and the like are used as an orientation or positional relationship based on that shown in the drawings, merely to facilitate description of the utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.
The flange sealing structure at the pipe penetrating position is shown in fig. 1, and comprises a pipe penetrating body, wherein a sleeve 1 is sleeved outside the pipe penetrating body, a flange assembly 2 is welded above the sleeve 1, a circle of fluororubber annular cushion block 6 is further arranged between the sleeve 1 and the pipe penetrating body, the flange assembly 2 consists of an upper flange 7 and a lower flange 8, the upper flange 7 and the lower flange 8 are fixed through a fastener 4, and a gasket 5 is further arranged between the upper flange 7 and the lower flange 8; the sleeve 1 is welded to the tube panel 9.
As shown in fig. 2-3, the diameter of the hole of the pipe penetrating panel 9 is smaller than the inner diameter of the sleeve 1 and larger than the outer diameter of the pipe penetrating, the diameter of the hole of the center of the flange component 2 is smaller than the inner diameter of the sleeve 1 and larger than the outer diameter of the pipe penetrating, so that the fluororubber ring cushion block 6 can be effectively compressed under the action of the fastener 4 along with the flange component 2, and the fluororubber cushion block 6 cannot leak from two sides of the structure.
As shown in fig. 4, the shape of the fluororubber ring cushion block 6 is two semicircular, the intersecting part is positioned and spliced through the fixing convex point 8 on one side and the concave positioning hole on the other side, the semicircular covers the two sides of the penetrating pipe, the replacement is convenient and quick during the overhaul, and the convex point and the concave positioning hole can enable the fluororubber ring cushion block not to be easily shifted in the use process.
Wherein, the fluororubber ring cushion blocks 6 are divided into two groups, are vertically stacked, are staggered by 90 degrees, are padded into the space between the sleeve and the penetrating pipe and are tightly attached to the outer wall of the penetrating pipe. The utility model adopts a mode of staggered splicing of the upper and lower overlapped splice seams of the four cushion blocks, and can greatly improve the sealing performance of the structure.
The two semicircular rings are connected in a staggered mode of 90-degree seam overlapping by an upper layer and a lower layer, and are padded into a space between the sleeve and the penetrating pipe to be tightly attached to the outer wall of the penetrating pipe.

The pipe that needs to pass through the panel passes through the center of the aperture of this structure. The sleeve at the perforated panel and the tube penetrating panel are in a welding mode, and the sleeve at the perforated panel and the sleeve flange are in a welding mode.
It is worth noting that the fluororubber ring cushion block is only used for illustration, and can be replaced by other sealing materials according to the use conditions in actual use, and the fluororubber ring cushion block is not limited, so that the sealing materials are required to be extruded by the pipe penetrating and the flange for ensuring the sealing performance, and the sealing materials have better compressibility. The sleeve height can be adjusted according to the actual use condition, but the shortest can not be less than 100mm.
The distance between the inner edges of the openings of the two holes and the outer wall of the pipeline is determined according to the result of the pipeline flexibility analysis. If not required, can be determined according to engineering practice, but cannot contact the outer wall of the perforating tube.
