Abstract
The utility model relates to a flange connecting structure for a water pump, which comprises two flanges arranged side by side, wherein the axes of the two flanges are positioned on the same straight line, the outer peripheral surfaces of the flanges are provided with limiting rings, the axial sections of the limiting rings are L-shaped, the inner rings of the limiting rings are connected with the outer peripheral surfaces of the flanges, gaps are arranged between the outer rings of the limiting rings and the outer peripheral surfaces of the flanges, the gaps between the two limiting rings and the flanges are arranged oppositely, and the flange connecting structure for the water pump is provided with the two limiting rings to realize the limiting and fixing of a rubber ring, so that the rubber ring can cover the joint of the two flanges, the sealing property is improved, and the service life is prolonged.
Description
Technical Field
The utility model particularly relates to a flange connecting structure for a water pump.
Background
The existing water pump flange connecting structure is fixed together through two common flanges through bolts, gaps exist on the periphery edge of the flange structure, corrosive liquid or gas can easily permeate into the flange structure, and therefore the service life of the flange connecting structure is shortened.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: in order to overcome the defects of the prior art, the flange connecting structure for the water pump is provided.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a flange connecting structure for a water pump comprises two flanges which are arranged side by side, the axes of the two flanges are positioned on the same straight line, a limiting ring is arranged on the outer peripheral surface of each flange, the axial section of each limiting ring is L-shaped, the inner ring of each limiting ring is connected with the outer peripheral surface of each flange, a gap is formed between the outer ring of each limiting ring and the outer peripheral surface of each flange, and the gaps between the two limiting rings and the flanges are arranged in a right-to-right mode;
an annular rubber ring is arranged between the two limiting rings, and two ends of the rubber ring are clamped in a gap between the limiting rings and the flange plate.
Preferably, the inner wall of the outer ring of the limiting ring is provided with a bulge, and the bulge is abutted against the outer ring of the rubber ring.
The flange connecting structure for the water pump has the advantages that the two limiting rings are arranged to limit and fix the rubber ring, so that the rubber ring can cover the joint of the two flange plates, the sealing performance is improved, and the service life is prolonged.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural view of a flange connection structure for a water pump according to the present invention;
in the figure: 1. the flange plate, 2, the spacing ring and 3, the rubber ring.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, a flange connection structure for a water pump includes two flanges 1 arranged side by side, the axes of the two flanges 1 are located on the same straight line, a limiting ring 2 is arranged on the outer circumferential surface of the flange 1, the axial cross section of the limiting ring 2 is L-shaped, the inner ring of the limiting ring 2 is connected with the outer circumferential surface of the flange 1, a gap is arranged between the outer ring of the limiting ring 2 and the outer circumferential surface of the flange 1, and the gaps between the two limiting rings 2 and the flange 1 are arranged opposite to each other;
an annular rubber ring 3 is arranged between the two limiting rings 2, and two ends of the rubber ring 3 are clamped in a gap between the limiting rings 2 and the flange plate 1.
Preferably, the inner wall of the outer ring of the limiting ring 2 is provided with a bulge, and the bulge is abutted against the outer ring of the rubber ring 3.
During the installation, stretch into in one of them ring flange 1 and spacing ring 2's clearance with the one end of rubber circle 3 earlier, then go into another ring flange 1 towards the other end card of rubber circle 3 by the opposite side again, just can make the both sides of rubber circle 3 go into respectively in two ring flange 1 and spacing ring 2's clearance, the clearance here is the opening of the L shape cross-section of spacing ring 2 in fact, the arch here not only plays and supports rubber circle 3, prevent that rubber circle 3 from taking place the function that shifts, but also play the function that compresses tightly rubber circle 3, make rubber circle 3 have better sealed effect.
Compared with the prior art, this a flange joint structure for water pump is through setting up two spacing rings 2 for realize spacing fixed to rubber ring 3, make rubber ring 3 can cover the seam of two ring flanges 1, improve the leakproofness, increase of service life.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
