In the figure: 1. a flange plate; 2. a circular table portion; 3. a through hole; 4. a mounting ring; 5. a seal ring; 51. an embedding part; 52. a convex portion; 53. a cambered surface; 54. a guide slope; 6. an elastic ring; 7. an annular groove; 8. an annular accommodating groove; 9. an annular caulking groove.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Example (b):
as shown in fig. 1 and 2, a novel flange for a valve, including a flange plate 1, one side of the flange plate 1 is fixedly connected with a circular platform part 2 coaxially arranged with the flange plate 1, an annular groove 7 is arranged on the other side of the flange plate 1, a mounting ring 4 is slidably connected in the annular groove 7, a sealing ring 5 is detachably connected in the mounting ring 4, an elastic component is arranged between the groove bottom of the annular groove 7 and the mounting ring 4, and the natural length of the elastic component and the thickness of the mounting ring 4 are greater than the groove depth of the annular groove 7.
As shown in fig. 3 and 4, the elastic assembly comprises an elastic ring 6 fixedly connected to the bottom of the annular groove 7, the elastic ring 6 is made of rubber material, and a gap is formed between the inner ring and the outer ring of the elastic ring 6 and the peripheral wall of the annular groove 7.
And the one side that the mounting ring 4 and elastic ring 6 kept away from annular groove 7 bonds, and annular caulking groove 9 has been seted up to one side that elastic ring 6 was kept away from to mounting ring 4, has seted up the annular holding tank 8 of round and annular caulking groove 9 intercommunication in the mounting ring 4, and the groove width of annular holding tank 8 is greater than the groove width of annular caulking groove 9.
Next, the sealing ring 5 includes an embedding portion 51 embedded in the annular receiving groove 8 and a convex portion 52 penetrating through the annular embedding groove 9 to the outside, one side of the convex portion 52 far from the embedding portion 51 is an arc surface 53, guide inclined surfaces 54 are provided on both sides of the embedding portion 51, a distance between the two guide inclined surfaces 54 gradually decreases from one side toward the convex portion 52, and a minimum distance between the two guide inclined surfaces 54 is equal to a groove width of the annular embedding groove 9.
When people only need use this flange to connect work, people can lift the flange of one side to make the flange touch the cambered surface 53 of convex part 52 in the lifting, thereby make the flange of one side can produce the component force towards annular groove 7 to sealing washer 5 and collar 4 under the guide effect of cambered surface 53, make sealing washer 5 and elastic ring 6 homoenergetic deformation in order to crumple from this.
Then when two ring flange 1's quotations are parallel to each other, there is certain interval between two ring flange 1, people can insert the through-hole 3 with the bolt through manual mode, then carry out threaded connection through nut and bolt and tighten up two ring flange 1, and after two ring flange 1 tighten up, elastic ring 6 can release elastic potential energy, can reply its state originally, thereby make it can promote seal ring 5 on collar 4 and the collar 4 and conflict with relative ring flange 1's quotation, make seal ring 5 have the effort towards 1 quotations of ring flange all the time, in order to reduce clearance between the two.
And through the setting of annular groove 7 and elastic ring 6 for both area of contact is less, and when the temperature was higher in the pipeline of being connected with ring flange 1, the efficiency that the temperature transmitted to on the sealing washer 5 was relatively poor, can not make the temperature of sealing washer 5 excessively rise and lead to its condition of life shortening such as emergence hardening.
Simultaneously, when people need change sealing washer 5, people only need exert oneself with it from annular holding tank 8 and annular caulking groove 9 pull out can, and when people need change the installation, can make two direction inclined plane 54 minimum interval one sides of sealing washer 5 aim at annular caulking groove 9, then people exert oneself it hard, make the embedding portion 51 of sealing washer 5 can take place elastic deformation and enter into annular caulking groove 9 in, later embedding portion 51 enters into annular holding tank 8 and later releases elastic potential energy reconversion, thereby make it can block in annular holding tank 8, and convex part 52 then runs through annular caulking groove 9.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
