Description

Sealing ring with retainer

Technical Field

The utility model relates to a sealing washer technical field especially relates to a sealing washer with holder.

Background

The sealing ring plays an important role in the connection between the two components, so that the gap between the two components is reduced, and the structure and material selection of the sealing ring have important significance on the sealing performance and the service life of the sealing ring; the sealing position of the pipeline joint is generally realized by a metal sealing ring, the joint of the existing pipeline is generally realized by structures such as flanges, but the existing sealing ring structure adopts an annular sheet or is additionally provided with a plurality of annular grooves, so that the sealing property and the applicability are poor; aiming at the problem, a C-shaped sealing ring is provided at present, and the sealing ring forms a contact pressure between a reinforced sealing ring and a rigid body through the action of medium internal pressure, so that the sealing ring can adapt to the sealing problems of high temperature resistance, high pressure resistance, corrosion resistance and the like in a fluid sealing system; however, the existing C-shaped sealing ring has certain problems, and when the C-shaped sealing ring is applied to a planar flange, a mounting groove needs to be formed, so that the C-shaped sealing ring is not convenient to mount and replace.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a sealing ring with a retainer.

In order to realize the purpose, the utility model adopts the following technical scheme:

a seal ring with a cage comprising:

the sealing ring comprises a sealing ring body, wherein the interior of the sealing ring body is of a hollow structure, an annular opening is formed in the inner wall of the sealing ring body, the annular opening is coaxial with the sealing ring body, and an annular spring is arranged in the sealing ring body;

the outer ring is fixedly sleeved outside the sealing ring body, and the outer ring is coaxial with the sealing ring body.

Preferably, the cross section of the outer ring is rectangular.

Preferably, the vertical width of the outer ring is smaller than the vertical width of the seal ring body.

Preferably, the outer ring edge is chamfered.

Preferably, the outer ring of the sealing ring body is provided with a plurality of embedded blocks in a surrounding manner, and the outer ring is provided with a plurality of embedded grooves matched with the embedded blocks in a surrounding manner.

Compared with the prior art, the beneficial effects of the utility model are that: the sealing ring has the characteristics of high-temperature strength, good resilience, corrosion resistance, fatigue resistance and the like of a C-shaped sealing ring, is particularly suitable for sealing high-temperature, high-pressure and high-vacuum media, and adopts the addition of the strength of a jacket and hydrostatic pressure to increase the sealing force at higher pressure; simultaneously, the rectangular outer ring is added to the sealing ring relative to a common C-shaped sealing ring, the outer ring plays a role of a retainer, so that the sealing ring can directly act on a planar flange without being provided with a mounting groove, meanwhile, the sealing ring is convenient to mount and replace, meanwhile, a structure for connection such as welding does not exist between the outer ring and the C-shaped sealing ring, the outer ring cannot influence the originally small contact surface of the C-shaped sealing ring and the use state of certain deformation, and the integral device is convenient to mount and dismount.

Drawings

Fig. 1 is a schematic perspective view of the present invention;

FIG. 2 is a schematic horizontal sectional structural view of the present invention;

fig. 3 is a schematic view of the vertical sectional structure of the present invention.

In the figure:

1 sealing ring body, 2 annular springs, 3 outer rings and 4 embedded blocks.

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. 1-3, a seal ring with a retainer includes:

the sealing ring comprises a sealing ring body 1, wherein the interior of the sealing ring body 1 is of a hollow structure, an annular opening is formed in the inner wall of the sealing ring body 1, the annular opening is coaxial with the sealing ring body 1, an annular spring 2 is arranged in the sealing ring body 1, the sealing ring body 1 adopts a C-shaped sealing ring structure, and meanwhile, the defects of the existing C-shaped sealing ring are overcome, so that the elasticity supplementation of the C-shaped sealing ring is a better solution, at present, more annular elastic parts are arranged in the C-shaped sealing ring to increase the elasticity, and the annular spring 2 is arranged in the C-shaped sealing ring to increase the effect of the C-shaped sealing ring;

when using, C type sealing washer, generally be applied to non-planar flange, when using to planar flange, need set up special mounting groove, in order to solve this problem, this sealing washer is equipped with outer loop 3 at 1 external fixation cover of sealing washer body, and outer loop 3 is coaxial with sealing washer body 1, form whole sealing washer structure, the cross-section of outer loop 3 is the rectangle, make this sealing washer can be used for planar flange's sealed in the condition that does not additionally set up the mounting groove, outer loop 3's vertical width is less than sealing washer body 1's vertical width, it is less to keep sealed contact, increase sealed stress, guarantee sealed effect, 3 edges of outer loop are handled through the chamfer, increase whole sealing washer's result of use.

When the C type sealing washer is using, there is the less condition with the less contact surface in sealed position, can produce certain deformation volume after installing itself simultaneously, just so can guarantee its higher effect, in order to avoid setting up of outer loop 3 to influence the effect of C type sealing washer, at first the thickness of outer loop 3 has been less than sealing washer body 1, guarantee that outer loop 3 has the effect of keeping the location to sealing washer body 1, should guarantee simultaneously that there is not fixed connection's such as similar welding structure between outer loop 3 and the sealing washer body 1, consequently in this sealing washer, sealing washer body 1 outer loop is around being provided with a plurality of embedding pieces 4, it is provided with a plurality of embedding flutings that match with embedding piece 4 to surround on the outer loop 3, the device is convenient for install and dismantle.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
