Abstract
The utility model discloses an engine exhaust structure, transition pipe including the tubulose intermediate junction body and connection booster, the one end of the tubulose intermediate junction body is plane flange structure up, the other end of the tubulose intermediate junction body is mouth of pipe structure, the tubulose intermediate junction body is gone up there is the erection support through the casting shaping, the transition external diameter of pipe is less than the internal diameter of mouth of pipe structure, the transition pipe is equipped with ring groove with the cooperation section of mouth of pipe structure, ring groove department is equipped with the piston ring. The utility model discloses an engine exhaust structure compact structure is firm, saves installation space, and can realize flexibility and sealing connection, can provide reliable support again.
Description
Technical field
This utility model relates to engine exhaust system field, particularly relates to a kind of engine exhaust mechanism.
Background technology
Engine exhaust bend pipe, generally connects with exhaustor, vent connection or supercharger, and engine exhaust temperature is up to more than 500-600 DEG C, and the high-temperature component of its external connection has exhaustor, acoustic filter, supercharger, vent connection etc..The highest temperature, makes these bear the parts expanded by heating of high temperature, and accessory size is the biggest, and expansion rate is the biggest.In order to reduce the infringement to supercharger (or exhaustor) of the thermal expansion dilation matrices, in connecting the pipeline before supercharger (or exhaustor), generally increase corrugated tube, but increase corrugated tube and need enough spaces, even and if add corrugated tube, due between corrugated tube and supercharger (or exhaustor), also tend to the support of gas exhaust piping, supporting the power (such as gravity, bending power etc.) that on the one hand only assume responsibility for a part of gas exhaust piping, another part power needs for supercharger (or exhaustor) and undertakes；On the other hand, due to the constraint effect supported, the heat cold expansion dilation matrices of part, supercharger (or exhaustor) is the most inevitably passed to.
Utility model content
The purpose of this utility model is to provide a kind of engine exhaust mechanism, and compact conformation consolidates, and saves installing space, and can realize flexible and be tightly connected, can provide again secure support.
For achieving the above object, this utility model provides a kind of engine exhaust mechanism, including tubulose intermediate connector and the transition conduit of connection supercharger, one end of described tubulose intermediate connector is flat supine flange arrangement, the other end of described tubulose intermediate connector is nozzle structure, erection support is had by casting on described tubulose intermediate connector, described transition conduit external diameter is less than the internal diameter of nozzle structure, described transition conduit is provided with piston ring groove with the section of cooperation of nozzle structure, is provided with piston ring at described piston ring groove.
As further improvement of the utility model, described piston ring has two, and all carries jagged, and the breach of two piston rings staggers 180 °.
As further improvement of the utility model, the centre of described flange arrangement is through hole, and described flange arrangement is provided around threaded mounting hole at through hole.
As further improvement of the utility model, the endoporus of described nozzle structure is step-like.
As further improvement of the utility model, the bottom surface of described erection support is plane, and described erection support is provided with bolt and fixes unthreaded hole.
Compared with prior art, the having the beneficial effect that of engine exhaust mechanism of the present utility model:
(1) compact conformation consolidates, and saves installing space.
(2) both it is provided that reliable and effective support, is provided that again simple type engine exhaust mechanism that is flexible and that be tightly connected, narrow for locus, the occasion of corrugated tube cannot be used again, especially embody its advantage.
By description below and combine accompanying drawing, this utility model will become more fully apparent, and these accompanying drawings are used for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the sectional view of engine exhaust mechanism.
Fig. 2 is the schematic diagram of engine exhaust mechanism.
Wherein, 1, intermediate connector；2, flange arrangement；3, nozzle structure；A, transition conduit；B, piston ring；4, erection support；5, unthreaded hole fixed by bolt；6, bolt.
Detailed description of the invention
With reference now to accompanying drawing, describing embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.
Refer to Fig. 1-2, described engine exhaust mechanism includes tubulose intermediate connector 1, the left end of described tubulose intermediate connector 1 is flat supine flange arrangement 2, the centre of described flange arrangement 2 is through hole, can connect acoustic filter, preprocessor or externally connected exhaust pipe road, flange arrangement 2 is provided around threaded mounting hole at through hole.nullThe right-hand member of described tubulose intermediate connector 1 is nozzle structure 3，The endoporus of described nozzle structure 3 is step-like，Transition conduit a that supercharger (or exhaustor) connects can extend in nozzle structure 3，Transition conduit a external diameter is less than the internal diameter of nozzle structure 3，Transition conduit a coordinates section to be machined with piston ring groove，Two piston ring b are put in piston ring groove，Piston ring b breach staggers about 180 °，Thus sealing effectiveness can be ensured，The displacement that the cold and hot expansion of piston ring b causes，Axially can move along tube hub direction，And because transition conduit a external diameter is less than nozzle structure 3 internal diameter，Also can move along caliber direction，Therefore may utilize sealing function and the radial direction of piston ring b、The flexible connecting structure that axially can slightly move，Both can guarantee that the engine exhaust mechanism sealing to aerofluxus，Trueness error and the dilatancy displacement of installation can be necessarily made up again in radial and axial the most all having，Rigid connection is avoided to cause part thermal expansion to tear.Having erection support 4, erection support 4 reliably to bear bigger vertical direction stress by casting on described tubulose intermediate connector 1, erection support is provided with bolt and fixes unthreaded hole 5, is arranged in unthreaded hole 5 fixed by bolt by bolt 6 and retrains its position.The bottom surface of described erection support 4 is plane such that it is able to form stable support.
Above in association with most preferred embodiment, this utility model is described, but this utility model is not limited to embodiment disclosed above, and should contain various carry out according to essence of the present utility model amendment, equivalent combinations.
