Description

High-pressure combined sealing ring

Technical Field

The utility model relates to the technical field of sealing rings, in particular to a high-pressure combined sealing ring.

Background

The sealing ring is also called an O-shaped sealing ring, is a fitting for sealing, and mainly comprises a V-shaped sealing ring, a U-shaped sealing ring, an O-shaped sealing ring, a rectangular sealing ring, a Y-shaped sealing ring, a YX-shaped sealing ring for holes, a check ring for YX-shaped holes, a YX-shaped check ring for shafts, a YX-shaped sealing ring for shafts and the like;

however, the existing sealing ring has a simple structure, poor tightness and elasticity, and can bear relatively high pressure, so we propose a high-pressure combined sealing ring.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model aims to provide a high-pressure combined sealing ring.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a high pressure combination sealing washer, includes the holding ring, all open a plurality of recesses on the inside wall and the lateral wall of holding ring, the joint has O type circle in the recess.

Preferably, an annular groove is formed in the support ring, and an inner spring ring and an outer spring ring are respectively arranged at two ends of the annular groove.

Preferably, the upper end and the lower end of the supporting ring are both provided with pressing grooves.

Compared with the prior art, the utility model has the following beneficial effects:

1. the O-shaped ring is attached to the sealing surface and seals, and the supporting ring and the O-shaped ring are elastic, so that the overall elasticity of the sealing ring is improved, and the sealing performance and the compression resistance of the O-shaped rings can be effectively improved;

2. the inner spring ring and the outer spring ring support the supporting ring, so that the overall elasticity of the sealing ring can be effectively improved;

3. when the liquid impacts the pressing groove, the supporting ring can expand to the two sides of the pressing groove, and then the O-shaped ring is extruded, so that the sealing performance can be further improved.

In the figure: 1. a support ring; 2. a groove; 3. an O-ring; 4. a ring groove; 5. an inner spring ring; 6. an outer spring ring; 7. and a pressing groove.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3, the present utility model provides a technical solution: the utility model provides a high pressure combination sealing washer, includes back-up ring 1, all open a plurality of recesses 2 on back-up ring 1's the inside wall and the lateral wall, the joint has O type circle 3 in the recess 2, like fig. 2, fig. 3, the shape size of recess 2 all supports O type circle 3 through recess 2 with O type circle 3 looks adaptation, back-up ring 1, O type circle 3 laminates and realizes sealedly with sealed face, back-up ring 1 all has elasticity with O type circle 3 to improve the whole elasticity of sealing washer, and a plurality of O type circles 3 can effectively improve leakproofness and compressive capacity.

Specifically, the inside of the support ring 1 is provided with a ring groove 4, and two ends of the ring groove 4 are respectively provided with an inner spring ring 5 and an outer spring ring 6, as shown in fig. 2 and 3, the inner spring ring 5 and the outer spring ring 6 support the support ring 1, so that the overall elasticity of the sealing ring can be effectively improved.

Specifically, the upper and lower ends of the support ring 1 are provided with pressing grooves 7, as shown in fig. 2 and 3, when the liquid impacts the pressing grooves 7, the support ring 1 expands towards two sides of the pressing grooves 7, and further presses the O-ring 3, so that the tightness can be further improved.

Working principle: as shown in fig. 2 and 3, the O-ring 3 is attached to the sealing surface and seals, and the supporting ring 1 and the O-ring 3 have elasticity, so that the overall elasticity of the sealing ring is improved, and the sealing performance and the compression resistance of the plurality of O-rings 3 can be effectively improved;

the inner spring ring 5 and the outer spring ring 6 support the support ring 1, so that the overall elasticity of the sealing ring can be effectively improved;

when the liquid impacts the pressing groove 7, the support ring 1 expands to both sides of the pressing groove 7, thereby pressing the O-ring 3, and further improving the sealability.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
