Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The technical scheme of the utility model is explained by combining the attached drawings.
As shown in FIG. 1, the purifying tank bolt seal strengthening device comprises a first sealing ring 1, a second sealing ring 2 and a third sealing ring 3; the first sealing ring 1, the second sealing ring 2 and the third sealing ring 3 are uniform and annular, and a middle through hole is sleeved on a bolt; the first sealing ring 1 is positioned between the top of the bolt and the upper flange, the second sealing ring 2 is positioned between the upper flange and the lower flange, and the third sealing ring 3 is positioned between the nut and the lower flange;
the first seal ring 1 further comprises a first bolt gap ring 7, the first bolt gap ring 7 is cylindrical, the axial lead of the first bolt gap ring 7 is perpendicular to the first seal ring 1, the top opening of the first bolt gap ring 7 is fixedly connected with a middle through hole of the first seal ring 1, the height of the first bolt gap ring 7 is not more than the thickness of the upper flange, and the first bolt gap ring 7 is used for tightly filling a gap between a bolt and an upper flange mounting hole;
the second sealing ring 2 further comprises a second bolt gap ring 8, the second bolt gap ring 8 is cylindrical, the axial lead of the second bolt gap ring 8 is perpendicular to the second sealing ring 2, the top opening of the second bolt gap ring 8 is fixedly connected with a middle through hole of the second sealing ring 2, the height of the second bolt gap ring 8 is not more than the thickness of the lower flange, and the second bolt gap ring 8 is used for tightly filling a gap between a bolt and the mounting hole of the lower flange.
The first bolt clearance ring 7, the second bolt clearance ring 8 and the bolts are in interference fit, so that the mounting hole gaps of the flanges are filled, and water is prevented from seeping out from the space between the upper flange and the lower flange. The openings of the first bolt gap ring 7 and the second bolt gap ring 8 are all downward, and the bolts are screwed downward, so that the structures of the first bolt gap ring 7 and the second bolt gap ring 8 cannot be damaged.
A second sealing ring 2 can seal between the flanges between the upper flange and the lower flange. An annular sealing ring groove is reserved on the flange in advance.
