Description

Technical Field

[0001] This utility model relates to the field of sealing sleeve technology, specifically a high-sealing turbine housing sealing sleeve. Background Technology

[0002] A turbine is a fan in a car or airplane engine that uses exhaust gases to blow fuel vapor into the engine, thereby improving engine performance. A turbine is a rotating power machine that converts the energy of a flowing working fluid into mechanical work. It is one of the main components of aircraft engines, gas turbines, and steam turbines. A sealing sleeve is needed during the installation and fixing of the turbine housing and cover to improve the stability and sealing of the housing installation.

[0003] A prior art patent application (application number 202423223730.6) describes a high-stability, leak-proof turbine housing sealing sleeve. The sleeve includes a sealing body comprising a first outer half-ring and a first inner half-ring. A second outer half-ring is inserted into one end of the first outer half-ring. Both the first and second outer half-rings contain a first reinforcing member, with a first insertion plate at one end and a first insertion groove at the other. The sealing sleeve's internal structure has high strength, strong resistance to compression, and good sealing performance, thus extending its service life. Furthermore, when the sealing sleeve is severely damaged locally, only the semi-circular sealing sleeve needs to be replaced, improving resource utilization and facilitating energy conservation. However, the internal structure of the outer sealing sleeve is relatively weak and prone to excessive deformation, affecting the sealing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a high-sealing turbine housing sealing sleeve to solve the problem that the internal structure of the sealing outer bushing in the prior art is of poor strength and is easily damaged by excessive deformation, which affects the sealing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing turbine housing sealing sleeve, comprising an outer sealing bushing and an inner bushing, wherein the outer sealing bushing is provided with an inner support reinforcement member, and the inner side of the inner support reinforcement member is provided with a limiting protrusion; the inner bushing includes an inner core sleeve, and the inner core sleeve is provided with a first sealing ring and a second sealing ring on both sides; a snap-fit ​​groove is formed between the inner core sleeve, the first sealing ring and the second sealing ring, and the inner bushing is snap-fitted to the inner and outer walls of the outer sealing bushing through the snap-fit ​​groove.

[0006] Furthermore, the inner core sleeve, the first sealing ring, and the second sealing ring are integrally formed, and all three are elastic rubber structures.

[0007] Furthermore, the snap-fit ​​groove is configured as an arc-shaped groove, and the width of the snap-fit ​​groove is equal to the thickness of the sealing outer bushing.

[0008] Furthermore, the inner core sleeve has a limiting hole on its side wall, and the limiting hole is engaged with the limiting protrusion.

[0009] Furthermore, both the inner support reinforcement and the limiting protrusion are alloy parts, and multiple limiting protrusions are arranged in a ring array on the inner wall of the inner support reinforcement.

[0010] Furthermore, the sealing outer bushing has positioning holes inside, and multiple positioning holes are provided at equal angles.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model utilizes an internal support reinforcement inside the sealing outer bushing. Both the internal support reinforcement and the limiting protrusion are alloy parts, which increases the structural strength inside the sealing outer bushing and prevents excessive deformation of the sealing outer bushing from affecting the sealing effect.

[0012] This utility model utilizes a first sealing ring and a second sealing ring provided on both sides of the inner core sleeve. A snap-fit ​​groove is formed between the inner core sleeve, the first sealing ring, and the second sealing ring. The inner liner is snapped onto the inner and outer walls of the sealing outer liner through the snap-fit ​​groove. The inner liner can seal the inner wall of the connection gap between the turbine housing and the housing cover, which helps to improve the sealing performance of the turbine housing and housing cover installation and fixation.

[0013] This utility model utilizes a limiting protrusion on the inner side of the inner support reinforcement and a limiting hole on the side wall of the inner core sleeve. The limiting hole and the limiting protrusion are interlocked, which facilitates the improvement of the stability of the inner core sleeve on the outer wall of the sealing outer bushing. Moreover, the inner bushing can be removed when not in use, which improves the flexibility of bushing use. Attached Figure Description
