Detailed description of the invention

In the following description, a large amount of concrete details is given to provide and this utility model is more understood thoroughly. It will be apparent, however, to one skilled in the art that this utility model embodiment can be carried out without these details one or more. In other example, in order to avoid obscuring with this utility model embodiment, technical characteristics more well known in the art are not described.

In order to thoroughly understand this utility model embodiment, detailed structure will be proposed in following description. Obviously, the execution of this utility model embodiment is not limited to the specific details that those skilled in the art has the knack of. Better embodiment of the present utility model is described in detail as follows, but except these detailed descriptions, this utility model can also have other embodiments.

With reference to Fig. 1 and Fig. 2, it illustrates according to a kind of sealing ring 100 of the present utility model, sealing ring 100 can be configured to circular, and it is provided with centre bore 140, so that sealing ring 100 is configured to annular. Sealing ring 100 has two sealing surfaces, respectively upper surface 131 and lower surface 132. Upper surface 131 is respectively used to the component (not shown) to be sealed with two and contacts with lower surface 132, thus the sealing realized between two components to be sealed.

Being additionally provided with at least two leakage-proof ring 120 on sealing ring 100, leakage-proof ring 120 arranges on the sealing surface, i.e. the quantity of the leakage-proof ring 120 being arranged on each sealing surfaces is at least two. Leakage-proof ring 120 may be provided on upper surface 131 or the lower surface 132 of sealing ring 100, also can be arranged on respectively on upper surface 131 and the lower surface 132 of sealing ring 100.

Additionally, the leakage-proof ring 120 being arranged on same sealing surfaces protrudes from this sealing surfaces on the thickness direction (axial direction) of sealing ring 100. In other words, for instance upper surface leakage-proof ring protrudes from upper surface 131 on the thickness direction of sealing ring, and lower surface leakage-proof ring protrudes from lower surface 132 on the thickness direction of sealing ring.

Further, on the thickness direction of sealing ring 100, the height that the leakage-proof ring 120 being arranged on same sealing surfaces protrudes from this sealing surfaces is identical.Such as, being arranged on the height that on same sealing surfaces two adjacent leakage-proof rings 120 protrude from this sealing surfaces identical, certainly, each leakage-proof ring 120 being arranged on same sealing surfaces protrudes from the height of this sealing surfaces can be all identical.

Specifically, in the shown embodiment, sealing ring 100 is annular, and its interior bone is circular centre bore 140, and the sealing ring 100 of annular can be used for fitting the component of such as flange etc. The upper surface 131 of sealing ring 100 and lower surface 132 are provided with the leakage-proof ring 120 of multilamellar arc-shaped convex, due on the thickness direction of sealing ring 100, the height that leakage-proof ring 120 protrudes from sealing surfaces (upper surface 131 or lower surface 132) is identical, therefore protrudes from the peak of same sealing surfaces (upper surface 131 or lower surface 132) on the thickness direction of each comfortable sealing ring 100 of each leakage-proof ring 120 all at grade. So, in sealed states, the peak of multiple leakage-proof rings 120 can all fit tightly with the component of such as flange etc., thus realizing the effect of leakproof layer by layer from inside to outside, this is equivalent to multiple O shape gasket ring set and arranges.

It is provided with the leakage-proof ring 120 on the axially projecting surface in sealing ring of at least two according to sealing ring upper ring cap of the present utility model, and on the thickness direction of sealing ring, the height that leakage-proof ring 120 protrudes from sealing surfaces is identical. The sealing property of sealing ring can being improved, improving service life, thus improve the safety coefficient of the product sealed.

Alternatively, at least two leakage-proof ring 120 can be arranged by concentric ring set as shown in the figure, and as shown in Figure 4, the first leakage-proof ring 121 and the second leakage-proof ring 122 are arranged concentrically. Certainly in a not shown embodiment, leakage-proof ring 120 can not also concentric ring be sheathed puts.

In order to reach better seal effect, leakage-proof ring 120 can be configured to continuous print ring-type, i.e. circumferentially continuous along sealing ring 100. So, the sealing surfaces of whole sealing ring 100 arranges continuous print leakage-proof ring 120, thereby may be ensured that the sealing effectiveness in the circumference of sealing ring 100. Multiple leakage-proof rings 120 can be configured to concentric ring set and arrange, and so can also strengthen sealing effectiveness.

With reference to Fig. 3 and Fig. 4, leakage-proof ring 120 can be circular arc along the cross section of sealing ring 100, and the part namely protruding from sealing surfaces is circular arc. It is of course also possible to be other shape.

Additionally, adjacent two leakage-proof ring 120 space sets, so, the space between adjacent two leakage-proof rings 120 can be used for depositing liquid when losing efficacy closer to the leakage-proof ring 120 of centre bore 140. Such as shown in Fig. 4, when flange because collision or fastening load deform, time sealing ring 100 and flange can not completely be fitted and there is spillage risk, first first leakage-proof ring 121 plays leakproof effect, if the first leakage-proof ring 121 cannot be fitted with flange face, liquid can be flowed in the groove formed between two spaced leakage-proof rings, and now the second leakage-proof ring 122 can play the effect of secondary leakproof, to ensure that liquid not easily leaks. Additionally, spaced leakage-proof ring 120 can reduce minimizing leakage-proof ring quantity, reduce cost.

Certainly, arrange at the adjacent non-interval of two leakage-proof rings 120, when being namely disposed adjacent, if the first leakage-proof ring 121 cannot be fitted with flange face, liquid can be flowed in the gap between two respective peaks of leakage-proof ring 120, and now, certain liquid storage effect can be played in the gap between peak.

Alternatively, sealing ring 100 being evenly distributed with multiple bolt hole 110, bolt hole 110 runs through sealing ring 100. Bolt hole 110 is uniformly distributed, for instance axial symmetry distribution or centrosymmetry distribution. Sealing ring 100 can be applied to axially fasten power via this bolt hole 110 by bolt (not shown), and sealing ring 100 can be fixed to component to be sealed. Those skilled in the art should appreciate that, the power that axially fastens that sealing ring 100 is acted on is not over compression load, so sealing ring 100 will not produce the deformation of such as conquassation etc, and sealing ring 100 can be made because of long-time stress will not to produce the phenomenon that the central axis of opposing seal circle 100 offsets.

In order to ensure the sealing effectiveness at bolt hole 110 place, can along the circumferentially disposed boss 111 of bolt hole 110, boss 111 protrudes from sealing surfaces on the thickness direction of sealing ring 100. And boss 111 to protrude from the height of sealing surfaces on the thickness direction of sealing ring 100 identical with the height that leakage-proof ring 120 protrudes from sealing surfaces on the thickness direction of sealing ring 100.

Specifically, on the thickness direction of sealing ring 100, two end faces of boss 111 are plane, to fit tightly the component of sealing ring 100 both sides respectively. As it is shown in figure 1, on the thickness direction of sealing ring 100, the height that boss 111 protrudes from sealing surfaces is identical with the height that the leakage-proof ring 120 being arranged on same sealing surfaces side protrudes from sealing surfaces. Namely, boss 111 flushes with the peak of arc-shaped convex leakage-proof ring 120, so, the upper surface of boss 111 can with component, such as a flange, laminating, the lower surface of boss 111 with another component, such as shell ring surface, can be fitted, thus ensureing that liquid will not pass through groove and flow in bolt hole 110, it is to avoid liquid leaks.

Optionally, in addition, at least one leakage-proof ring 120 can be provided with between boss 111 and centre bore 140. So, in sealed states, the peak of the peak of boss 111 and the leakage-proof ring 120 that is arranged between boss 111 and centre bore 140 can all fit tightly with the component of such as flange etc., thus realizing the effect of leakproof layer by layer from inside to outside, this is equivalent to multiple O shape gasket ring set and arranges. Further, be arranged on the leakage-proof ring 120 between boss 111 and centre bore 140 can and boss 111 interval arrange, as described above, there is gap between spaced leakage-proof ring 120 and boss 111, can be used for liquid storage.

In the shown embodiment, same sealing surfaces upper ring cap is provided with four leakage-proof rings, and certainly, the quantity of leakage-proof ring is not limited to the quantity of the disclosure. According to demand and/or expectation, the quantity of the leakage-proof ring on different sealing surface also can be different, for instance, the upper surface 131 of sealing ring 100 arranges four leakage-proof rings, and three leakage-proof rings is set on the lower surface 132 of sealing ring 100. And, the leakage-proof ring on different sealing surface protrudes from the height of this leakage-proof ring can be different. It addition, sealing ring can be configured to one, for instance, leakage-proof ring and sealing surfaces are one-body molded.

Simple, easy to process, simple and quick according to ring structure of the present utility model; Changed into linear sealing layer by layer by original flat seal, enhance the reliability of sealing ring, the problem solving liquid leakage, save the repair time, reduce production cost.

This utility model is illustrated already by above-mentioned embodiment, but it is to be understood that, above-mentioned embodiment is only intended to citing and descriptive purpose, and is not intended to be limited within the scope of described embodiment this utility model.In addition it will be understood by those skilled in the art that; this utility model is not limited to above-mentioned embodiment; more kinds of variants and modifications can also be made, within these variants and modifications all fall within this utility model scope required for protection according to instruction of the present utility model.
