Description
Technical field
The present invention relates to technical field of engines, in particular to a kind of exhaust pipe with heat-proof device and there is the exhaust
The engine of pipe.
Background technique
For marine engine, in order to reduce cabin temperature, while considering the safety of operator, laws and regulations requirement for
The component that exposed surface reaches 220 DEG C or more must increase protective device.
Currently used heat-insulated mode such as wraps up one layer of very thick thermal insulation layer in exhaust pipe periphery, heat-insulated to realize, but
It is, so set, both unsightly or to the arrangement of surrounding components causing very big difficulty.In addition, can also be in the week of exhaust pipe
One layer of water jacket of casting is enclosed, makes to form water cavity between water jacket and exhaust pipe, cooling water passes through from water cavity, direct cooled exhaust pipe, row
Tracheae and water jacket are integrally cast.But since water jacket and exhaust pipe are cast in integrated, water cavity directly connects with exhaust pipe
Touching, the heat that water jacket is taken away when engine operation is too many, causes booster turbine energy insufficient, especially for high performance yacht
With engine, Matching of Turbocharger and type selecting are extremely difficult.
Therefore, how a kind of exhaust pipe with heat-proof device is provided, is art technology to reduce the temperature drop of exhaust pipe
Personnel's technical problem urgently to be resolved.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of exhaust pipes with heat-proof device, to reduce exhaust pipe
Temperature drop.In addition, another object of the present invention is to provide a kind of engines with the above-mentioned exhaust pipe with heat-proof device.
To achieve the above object, the invention provides the following technical scheme:
A kind of exhaust pipe with heat-proof device, including exhaust tube body, further include being set in the exhaust tube body
The water jacket in outside has gap between the water jacket and the outer wall of the exhaust tube body.
Preferably, in above-mentioned exhaust pipe, the water jacket is U-shaped ring structure.
Preferably, in above-mentioned exhaust pipe, the water jacket is the C-shaped ring structure that multistage straight pipeline is in turn connected to form.
A kind of engine, including exhaust pipe and cylinder cap, wherein the exhaust pipe is described in any of the above embodiments with heat-insulated
The exhaust pipe of device.
Preferably, in above-mentioned engine, the discharge of the coolant liquid of the entrance of the water jacket of the exhaust pipe and the cylinder cap
Mouth sealing connection, the outlet of the water jacket connect water pump.
Preferably, in above-mentioned engine, the inlet of the water jacket is provided with for close with the outlet of the cylinder cap
Seal the sealing ring of connection.
Preferably, in above-mentioned engine, the bottom of the water jacket is fixed on the cylinder cap.
Preferably, in above-mentioned engine, the top of the water jacket is fixed on the cylinder cap by water jacket bracket.
Preferably, in above-mentioned engine, the outlet of the cylinder cap is located at the exhaust end side of the exhaust pipe.
As can be seen from the above technical solutions, a kind of exhaust pipe with heat-proof device disclosed in this invention, by water jacket
Gap is set between exhaust tube body, can not only guarantee that the temperature of exposed surface can satisfy regulation demand, can also make water
Set is two relatively independent structures with exhaust tube body, and water jacket is not directly contacted with exhaust tube body, alleviates water jacket and row
The too many problem of the heat that tracheae ontology is taken away because directly contacting solves the situation of booster turbine energy deficiency, reduces
For high performance trip boat engine, the difficulty of Matching of Turbocharger and type selecting.

Specific embodiment
In view of this, core of the invention is to provide a kind of exhaust pipe with heat-proof device, to reduce exhaust pipe
Temperature drop.Another core of the invention is the provision of a kind of engine with the above-mentioned exhaust pipe with heat-proof device.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
As shown in Figure 1-Figure 3, the invention discloses a kind of exhaust pipes with heat-proof device, including exhaust tube body 1, also
Including being set in the water jacket 2 in 1 outside of exhaust tube body, and there is gap between water jacket 2 and the outer wall for being vented tube body 1.It will
Gap is set between water jacket 2 and exhaust tube body 1, can not only guarantee that the temperature of exposed surface can satisfy regulation demand, also
It can make water jacket 2 and exhaust 1 two relatively independent structures of tube body, water jacket 2 is not directly contacted with exhaust tube body 1, is alleviated
The too many problem of the heat that water jacket 2 is taken away with exhaust tube body 1 because directly contacting, it is insufficient to solve booster turbine energy
The case where, it reduces for high performance trip boat engine, the difficulty of Matching of Turbocharger and type selecting.
In specific embodiment, above-mentioned water jacket 2 is U-shaped ring structure, is set in exhaust tube body using the water jacket 2 of opening
1 outside, in order to which water jacket 2 is mounted on the outside of exhaust tube body 1.For water jacket 2 and exhaust the distance between tube body 1, with
And the size of water jacket 2 can be configured according to different needs, and in protection scope.
In another embodiment, above-mentioned water jacket 2 can also be in turn connected to form C-shaped ring structure for multistage straight pipeline.Right
In 2 design process of water jacket, needing to guarantee water jacket 2 not influences the installation of existing structure, it will be appreciated by persons skilled in the art that
Model is being protected meeting the water jacket 2 being set in be vented on the outside of tube body 1 and with gap arrangement between exhaust tube body 1
In enclosing.C-type structure sequentially connected for multistage straight pipeline is the single piece of casting, avoids revealing.
Above-mentioned water jacket 2 is set as open annular structure, and water jacket 2 is single piece, and sealing surface is few, and disclosure risk is low, and structure can
It leans on.The integral layout of engine-side is more compact, while meeting functional and industrial design requirement.
