Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a flange structure with a sealing and fastening function comprises a first flange 1, a second flange 2 and fixing bolts 4, wherein an annular reinforcing part 3 is further arranged on one side, away from the first flange 1, of the second flange 2.
When the installation, with first flange 1 with fix on second flange 2, install reinforcement 3 outside first flange 1 and second flange 2, pass through first flange 1, second flange 2 and reinforcement 3 in proper order through fixing bolt 4 at last, realize the fixed mounting to whole structure.
As shown in fig. 3, the outer ring of the first flange 1 is folded in the vertical direction to form a ring-shaped portion 11, that is, the first flange 1 has an annular cavity inside, and the second flange 2 is installed inside the annular cavity when the first flange is installed.
As shown in fig. 4, the periphery of the second flange 2 is provided with a receiving ring groove 21, that is, the middle part of the second flange 2 protrudes upward, so that the outer part of the second flange 2 is lower than the middle part, and when the second flange 2 is fixed to the first flange 1, a gap is formed between the receiving ring groove 21 and the side wall of the first flange 1.
The utility model provides a flange structure with sealed fastening function, packing ring position squints easily when installing current flange structure to lead to the not strong problem of leakproofness to provide improved design. Specifically include second flange 2, the upside of second flange 2 is equipped with first flange 1, the downside of second flange 2 is equipped with reinforcement 3, fix second flange 2 in the centre from two directions through first flange 1 and reinforcement 3, wherein the annular part 11 of first flange 1 turns over towards the centre, accomodate the edge of second flange 2 wherein, and reinforcement 3 accomodates the terminal surface of second flange 2 wherein from the terminal surface, can form the all-round fastening to second flange 2, set up sealing washer 51 in sealed chamber 5 in addition, can further improve the leakproofness to first flange 1 and second flange 2 edge.
Wherein the seal cavity 5 is annular, and its cross-section is the Z style of calligraphy, and sealing washer 51 is the rubber material, and the cross-section of sealing washer 51 and the cross-section looks adaptation of seal cavity 5, so set up for the seepage possibility greatly reduced of first flange 1 and second flange 2 junction, thereby improved the sealing performance of first flange and second flange effectively.
In addition, by arranging the Z-shaped seal ring 51, the situation that the seal ring 51 is deviated in the installation process to cause poor sealing performance can be effectively avoided.
