Description
Technical field
The present invention relates to engine exhaust pipe field, particularly a kind of sealing configuration of engine exhaust pipe.
Background technique
As shown in Figure 1, the seal ring 13 that the connection of existing motor two sections of outlet pipes 11,12 uses is Steel material structures, and namely now engine exhaust pipe each section of sealing uses the seal ring of Steel material to seal.
Adopt the sealing configuration of seal ring of Steel material to meet seal request, often leak air, Leakage, engine work Tail Pipe Temperature can reach more than 700 DEG C, and when using steel seal ring test-run a machine, thermal shield blackening, has illustrated gas leakage.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of sealing configuration of simple and reasonable engine exhaust pipe, the sealing configuration of this engine exhaust pipe adopts the seal ring of refractory fibrous material making, during assembling, seal ring is put into outlet pipe draw-in groove to be connected with another section of outlet pipe again, thus the sealing surface between two sections of outlet pipes plays seal action, high temperature condition lower seal is effective, oil-proof, air tight, technological operation is simple, overall cost is low, solves the gas leakage Leakage of each intersegmental connection of engine exhaust pipe.
For achieving the above object, the invention provides a kind of sealing configuration of engine exhaust pipe, the sealing configuration of this engine exhaust pipe comprises: first paragraph outlet pipe, and its one end is sealing insertion end, and has circumferential draw-in groove; Second segment outlet pipe, the sealing insertion end grafting of itself and described first paragraph outlet pipe forms sealing configuration; And seal ring, it adopts refractory fibrous material, and sealing ring is arranged on the connection sealing effect improving described first paragraph outlet pipe and second segment outlet pipe in described circumferential draw-in groove.
Preferably, in technique scheme, circumferential draw-in groove is one or multi-channel.
Preferably, in technique scheme, circumferential draw-in groove is twice.
Preferably, in technique scheme, twice circumference draw-in groove be arranged in parallel.
Compared with prior art, the present invention has following beneficial effect: the sealing configuration of this engine exhaust pipe adopts the seal ring of refractory fibrous material making, during assembling, seal ring is put into outlet pipe draw-in groove to be connected with another section of outlet pipe again, thus the sealing surface between two sections of outlet pipes plays seal action, high temperature condition lower seal is effective, oil-proof, air tight, technological operation is simple, overall cost is low, solves the gas leakage Leakage of each intersegmental connection of engine exhaust pipe.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the sealing configuration of available engine outlet pipe.
Fig. 2 is the schematic diagram of the sealing configuration of engine exhaust pipe of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 2, concrete structure according to the sealing configuration of the engine exhaust pipe of the specific embodiment of the invention comprises: first paragraph outlet pipe 21, second segment outlet pipe 22 and seal ring 23, wherein, first paragraph outlet pipe 21 and the insertion end of second segment outlet pipe 22 have multiple tracks circumference draw-in groove, seal ring 23 adopts refractory fibrous material, it is arranged in this circumferential draw-in groove, the original physics of seal ring 23 is not destroyed 1000 DEG C time, chemical characteristics, expanded by heating during high temperature, and its system expanded is higher than the coefficient of the material expansion of outlet pipe own, thus the sealing surface between two sections of outlet pipes plays seal action.Adopt the seal ring good sealing effect under the high temperature conditions of refractory fibrous material, oil-proof, air tight, technological operation is simple, overall cost is low, solves the gas leakage Leakage of each intersegmental connection of engine exhaust pipe.
Specifically, one end and the second segment outlet pipe 22 of first paragraph outlet pipe 21 insert and form sealing configuration, first paragraph outlet pipe 21 and the insertion end of second segment outlet pipe 22 have multiple tracks circumference draw-in groove, and this multiple tracks circumference draw-in groove is for holding seal ring to improve the connection sealing effect of first paragraph outlet pipe 21 and second segment outlet pipe 22.Preferably, circumferential draw-in groove is the twice be arranged in parallel, and the circumferential draw-in groove that twice be arranged in parallel is provided with seal ring, is used for improving further the connection sealing effect of first paragraph outlet pipe 21 and second segment outlet pipe 22.
Seal ring 23 adopts refractory fibrous material, it is arranged in this circumferential draw-in groove, for replacing the seal ring of existing Steel material structure, the seal ring 23 of refractory fibrous material does not destroy its original Wuli-Shili-Renli system approach 1000 DEG C time, expanded by heating during high temperature, and its system expanded is higher than the coefficient of the material expansion of outlet pipe own, thus the sealing surface between two sections of outlet pipes plays seal action.Adopt the seal ring good sealing effect under the high temperature conditions of refractory fibrous material, oil-proof, air tight, technological operation is simple, overall cost is low, solves the gas leakage Leakage of each intersegmental connection of engine exhaust pipe.
The advantage that the sealing configuration of the seal ring of the refractory fibrous material that first paragraph outlet pipe 21 and second segment outlet pipe 22 are formed has:
1, refractory seal are effective:
Engine work Tail Pipe Temperature can reach more than 700 DEG C, and after using high temperature fiber seal ring, thermal shield not blackening during test-run a machine, illustrates the problem that do not leak air.
2, cost is low
Compared with raw steel sealing structure ring, use the connecting means of high temperature fiber seal ring to have cost advantage, overall cost declines about 20%.
To sum up, the sealing configuration of this engine exhaust pipe adopts the seal ring of refractory fibrous material making, during assembling, seal ring is put into outlet pipe draw-in groove to be connected with another section of outlet pipe again, thus the sealing surface between two sections of outlet pipes plays seal action, high temperature condition lower seal is effective, oil-proof, air tight, technological operation is simple, overall cost is low, solves the gas leakage Leakage of each intersegmental connection of engine exhaust pipe.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
