The utility model has better sealing performance, larger compression amount, good rebound resilience and vibration following performance; the sealing ring has the function of bidirectional sealing inwards and outwards; the sealing ring has smaller reaction on the flange and simple design structure.
Description
Technical Field
The utility model relates to an engine seal technical field, concretely relates to two-way many W type metal thin wall ring of obturating.
Background
The sealing device is an indispensable important part in modern fluid machinery as a device for preventing leakage and external impurities and dust from entering the inside of a working environment in an electromechanical product. The W-shaped metal sealing ring is widely applied to fifth-generation engines due to the excellent sealing performance of the W-shaped metal sealing ring.
The W-shaped sealing ring guarantees sealing, simultaneously considers the advantages of large axial compression displacement, moderate rigidity, good rebound resilience and the like, has the difficult vibration following performance and durability, and can provide stable sealing under the conditions of high temperature and high pressure for aerospace equipment. But the working environment is complex (high temperature and high pressure, frequent vibration and strong corrosivity), the performance requirement is high (moderate rigidity, good sealing performance, high strength, good vibration following performance and long service life), and meanwhile, the structure is simple, the metal wall is thin, so that the sealing performance is extremely difficult to improve.
Therefore, the bidirectional multi-W-shaped sealing ring is provided on the basis of the single-W-shaped sealing ring, and compared with the traditional W-shaped sealing ring, the contact area between the bidirectional multi-W-shaped sealing ring and a flange plate is twice that of the W-shaped sealing ring, the contact area is increased, and the sealing performance is better; the bidirectional multi-W sealing ring has large axial compression amount, can realize larger compression ratio and does not yield; the sealing loop has good elasticity and good vibration following property; the sealing ring has the characteristics of an inward W-shaped sealing ring and an outward W-shaped sealing ring, can be used for sealing inwards and outwards, and has richer available scenes; the sealing ring has small rigidity and small reaction load on the flange; the seal has simple design and easy manufacture.
Disclosure of Invention
The utility model discloses the problem that will solve is: the bidirectional multi-W-shaped metal thin-wall sealing ring is better in sealing performance, larger in compression amount, and good in rebound resilience and vibration following performance; the sealing ring has the function of bidirectional sealing inwards and outwards; the sealing ring has smaller reaction on the flange and simple design structure.
The utility model discloses a solve the technical scheme that above-mentioned problem provided and do: a bidirectional multi-W-shaped metal thin-wall sealing ring comprises a sealing ring with an annular structure, wherein the cross section of the sealing ring is two multi-W shapes arranged in a back direction, and each multi-W shape is provided with two wave crests and three wave troughs; one of the two multi-W-shaped bodies has inward opening and outward opening, and the two multi-W-shaped bodies are fixedly welded at the middle wave trough.
Compared with the prior art, the utility model has the advantages that: the contact area of the bidirectional multi-W sealing ring and the flange plate is twice that of the traditional W-shaped sealing ring, the contact area is increased, and the sealing performance is better; the axial compression amount of the bidirectional multi-W sealing ring is large, so that a large compression ratio can be realized and yield is avoided; thirdly, the sealing loop has good elasticity and vibration following performance; the sealing ring has the characteristics of an inward W-shaped sealing ring and an outward W-shaped sealing ring, can be used for sealing inwards and outwards, and is richer in available scenes; fifthly, the sealing ring has low rigidity and small reaction load on the flange; sixthly, the seal is simple in design and easy to manufacture.
Drawings
The accompanying drawings, which are described herein, serve to provide a further understanding of the invention and constitute a part of this specification, and the exemplary embodiments and descriptions thereof are provided for explaining the invention without unduly limiting it.
Fig. 1 is a top view of the present invention;
fig. 2 is a cross-sectional view a-a of fig. 1 of the present invention;
the attached drawings are marked as follows: 1. and 2, a sealing ring, 2, a wave trough welding part, 3, a wave trough, 4, a wave crest, 5 and multiple W shapes.
Detailed Description
The following detailed description will be made with reference to the accompanying drawings and examples, so that how to implement the technical means of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.
The specific embodiment of the utility model is shown in fig. 1 and fig. 2, a bidirectional multi-W-shaped metal thin-wall sealing ring, which comprises a sealing ring 1 with an annular structure, wherein the cross section of the sealing ring 1 is two multi-W-shaped 5 arranged back to back, and the multi-W-shaped 1 is provided with two wave crests 4 and three wave troughs 3; one of the two multi-W-shaped bodies 1 has an inward opening and the other multi-W-shaped body 5 has an outward opening, and the two multi-W-shaped bodies 1 are fixedly welded at the middle wave trough 3.
The utility model discloses a concrete theory of operation: the bidirectional multi-W-shaped metal sealing ring is arranged between the flange plates with axial compression, and high-temperature and high-pressure airflow flows in from one flange ring to the other flange ring; the bidirectional multi-W-shaped metal sealing ring can be arranged between different flange rings to realize radial inward or outward gas sealing; the bidirectional multi-W-shaped metal sealing ring has better elasticity and can bear larger axial compression; meanwhile, the double-layer sealing is realized, the contact area with the flange ring is larger, and the sealing performance is better.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. The present invention is not limited to the above embodiments, and the specific structure thereof is allowed to be changed. All changes which come within the scope of the independent claims of the invention are to be embraced within their scope.
