Description
Technical field
The utility model relates to pipeline connecting device field, is specifically related to a kind of anti-low temperature special flange.
Background technique
The normally integrated cast member of flange or forge piece, bottom is disk, top is conical or columniform pipe, disk is distributed with multiple pilot hole, flange passes through bolts assemblies, during assembling, mating face needs arrange seal ring, by the mating face of the flange of both sides, sealing is realized to the pressure of seal ring.Use under anti-low temperature special flange is mainly used for low temperature environment, because at low ambient temperatures, flange can be subject to cold events, and the bolt of locking flange can loosen, and sealing can decline, and therefore, needs to make improvements.
Summary of the invention
The purpose of this utility model is the problem of the sealing difference existed for existing anti-low temperature special flange pointed in background technique, provides a kind of anti-low temperature special flange of good airproof performance.
The technological scheme realizing goal of the invention of the present utility model is as follows:
A kind of anti-low temperature special flange, it comprises the first flange, the second flange and seal ring, first flange and the second flange include disk and are arranged on the connecting tube on disk, the disk of the first flange and the second flange is distributed with multiple pilot hole, the disk bottom surface of the first flange is provided with the projection of circular arc, the disk bottom surface of the second flange is provided with the groove with the male cooperation on the first flange, the first flange, the second flange are fixedly connected with by screw bolt and nut with seal ring.
In order to strengthen combination force that is protruding and groove, the arc round angle of described projection is 30 ° ~ 60 °.
The advantage of anti-low temperature special flange of the present utility model is: anti-low temperature special flange structure of the present utility model is simple, by arranging projection and the groove of circular arc on the bottom surface of the disk of flange, enhance the first flange, combination force between the second flange and seal ring, enhance the sealability of anti-low temperature special flange, even if at low ambient temperatures, flange, by cold events, also can ensure the combination force between flange, still can keep good sealability.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-low temperature special flange of the present utility model;
Fig. 2 is the schematic bottom view of the first flange of anti-low temperature special flange of the present utility model;
In figure, 1 is the first flange, and 11 is disk, and 12 is connecting tube, and 13 is pilot hole, and 14 is protruding, and 15 is groove, and 2 is the second flange, and 3 is seal ring.
Embodiment
The anti-low temperature special flange of the shown one that sees figures.1.and.2, it comprises the first flange 1, second flange 2 and seal ring 3, the connecting tube 12 that first flange 1 and the second flange 2 include disk 11 and be arranged on disk 11, the disk 11 of the first flange 1 and the second flange 2 is distributed with multiple pilot hole 13, disk 11 bottom surface of the first flange 1 is provided with the projection 14 of circular arc, disk 11 bottom surface of the second flange 2 is provided with groove 15, first flange 1, second flange 2 coordinated with the projection 14 on the first flange 1 to be fixedly connected with by screw bolt and nut with seal ring 3.
In order to strengthen the combination force of protruding 14 and groove 15, the arc round angle of described projection 14 is 30 ° ~ 60 °.
Anti-low temperature special flange of the present utility model is when assembling, seal ring 3 is placed between the first flange 1 and the second flange 2, then by the projection 14 on the first flange 1 and the second flange 2 and groove 15 corresponding, then by bolt by the first flange 1, second flange 2 and seal ring 3 are locked, the projection 14 on the first flange 1 is made to extend in groove, and make seal ring 3 that bulging deformation occur, strengthen the first flange 1, combination force between seal ring 3 and the second flange 2, enhance the sealability of anti-low temperature special flange, even if at low ambient temperatures, flange is by cold events, also the combination force between flange can be ensured, still good sealability can be kept.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is not when departing from spirit and scope of the present utility model; can also make various conversion and change and obtain corresponding equivalent technological scheme, therefore all equivalent technological schemes all should be included into scope of patent protection of the present utility model.
