Specific implementation mode
Below in conjunction with the accompanying drawings, the specific implementation mode of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figure 1, the concrete structure of the sealing structure of segmented exhaust system according to the preferred embodiment of the present invention
Including:First sectional type exhaust tube 1, spring 2, gasket seal 3, hold-down mechanism 4 and the second sectional type exhaust tube 5.Wherein, first
One end of sectional type exhaust tube 1 forms sliding sleeve with the second sectional type exhaust tube 5 and fills connection structure, spring, gasket seal, compression
Mechanism is nested between the first sectional type exhaust tube 1 and the second sectional type exhaust tube 2 so that gasket seal hold-down mechanism with
Two sections of exhaust pipes are filled under spring pre-tightening force effect and hold-down mechanism is formed by formation elastic packing region among vee gutter,
No matter exhaust pipe is small deformation under cryogenic, still moderate finite deformation under the high temperature conditions, can be transferred through voluntarily adjusting
It is effectively connected between sectional type exhaust tube to control, therefore the deformations such as exhaust pipe elongation under various temperature conditions can be met and caused
Junction effective sealing, improve the economy and reliability of engine.
Specifically, one end of the first sectional type exhaust tube 1 has as inserted terminal, one end of the second sectional type exhaust tube 5
There is the inserted terminal with the first sectional type exhaust tube 1 to be adapted to the grafting seam allowance of grafting so that the first sectional type exhaust tube 1 and second point
Segmentation exhaust pipe 5 forms sliding sleeve and fills connection structure.
Spring 2 is sleeved between the first sectional type exhaust tube 1 and the second sectional type exhaust tube 2.
The section of gasket seal 3 is triangle, and uses elastic material, which is flexible, deformable, high temperature resistant
Sealing medium.
Hold-down mechanism 4 is pipe sleeve shape, has ladder internal diameter, wherein major diameter section and the grafting of the second sectional type exhaust tube 5 stop
Mouth adaptation suit, path section are adapted to suit with the inserted terminal of the first sectional type exhaust tube 1, and major diameter section and path section are inclined-plane mistake
It crosses.Hold-down mechanism 4 is sleeved on the inserted terminal of the first sectional type exhaust tube 1 by path section, and second point is sleeved on by major diameter section
The grafting seam allowance of segmentation exhaust pipe 5, spring 2 are set between hold-down mechanism 4 and the first sectional type exhaust tube 1,3 sets of gasket seal
It is located between hold-down mechanism 4 and the second sectional type exhaust tube 5, the first segmentation of filling under hold-down mechanism and spring pre-tightening force effect
Formula exhaust pipe 1, the second sectional type exhaust tube 2, hold-down mechanism form sealing area among being formed by vee gutter.
As shown in Fig. 2, completing preceding state in non-assembly between exhaust pipe and exhaust pipe.Spring is in nature elongation at this time
State, in the raw, spring, gasket seal, hold-down mechanism are nested into the first sectional type exhaust tube 1 and to gasket seal
Between two-section formula exhaust pipe 2.As shown in figure 3, between exhaust pipe and exhaust pipe after assemble state.First segmented
Exhaust pipe 1 and the second sectional type exhaust tube 2 are completed to assemble, at this point, spring is in impaction state, under the contractive condition of spring,
Compressed spring is arranged by the first sectional type exhaust tube 1, the second segmented that the elastic force effect of spring pushes gasket seal to be pressed into
Tracheae 2, hold-down mechanism are formed by among vee gutter, due to hold-down mechanism oblique angle design at 45 °, compressed gasket seal
Because there are resilience performance, sectional type exhaust tube axially and radially on there is pressing force, therefore can be by gasket seal
It is pressed to the end face seal face on 1 cylindrical surface of the first sectional type exhaust tube and the second sectional type exhaust tube 2, forms sealing area.Row
Tracheae is worked in the case where high and low temperature alternative occurs, and exhaust pipe has different elongations thus, therefore the first segmented is arranged
Tracheae 1 and the second sectional type exhaust tube 2 have a relative movement, but due to there is a pretightning force force effect of spring, no matter exhaust pipe
It is under high/low temperature condition, spring all can push hold-down mechanism under pre-pressing force effect, to make gasket seal be in always
Compressive state, playing still can effectively be sealed under high/low temperature change condition.
To sum up, the gasket seal of the sealing structure of the segmented exhaust system is under hold-down mechanism and spring pre-tightening force effect
Two sections of exhaust pipes of filling and hold-down mechanism form elastic packing region among being formed by vee gutter, no matter exhaust pipe is low
Small deformation under the conditions of temperature, still moderate finite deformation under the high temperature conditions, can be transferred through voluntarily adjusting and be arranged with segmented to control
It is effectively connected between tracheae, therefore exhaust pipe elongation etc. under various temperature conditions can be met and deform the effective close of caused junction
Envelope, improves the economy and reliability of engine.
The description of the aforementioned specific exemplary embodiment to the present invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the present invention and its actually answering
With so that those skilled in the art can realize and utilize the present invention a variety of different exemplary implementation schemes and
