Abstract
The invention discloses an expansion joint for an exhaust pipe of an internal combustion engine, which comprises an inserted pipe and a sleeve. Both the inserted pipe and the sleeve are cylindrical short pipes of which one ends are provided with flanges. Pipe orifices of the inserted pipe and the sleeve are opposite. The sleeve is sleeved outside the inserted pipe. The outer wall of the inserted pipe is provided with at least one gas ring groove; a gas ring is arranged in the gas ring groove; preferably, three gas rings and three gas ring grooves are provided; the outer wall of the inserted pipe is in sealed connection with the inner wall of the sleeve through the gas rings; and the flange ends of the inserted pipe and the sleeve are respectively connected with an exhaust port and the exhaust pipe of the internal combustion engine. When the internal combustion engine works, the inserted pipe can freely extend and retract in the sleeve, in the peripheral direction, the inserted pipe can also be well compensated due to the elasticity of the gas rings; and the expansion joint is of a split structure and both ends of the expansion joint are connected only by the gas rings, so the transferred vibration is low.
Description
Technical field
The present invention relates to a kind of expansion pipe, relate in particular to the effective expansion pipe of a kind of I. C. engine exhaust.
Background technique
Vibration is very big during internal combustion engine; Need between machine relief opening and outlet pipe, expansion pipe be set, to slow down the influence of vibration to outlet pipe, the expansion pipe of generally using at present is corrugated expansion joint; Elastic damping transfer of vibration through ripple; But because corrugated expansion joint still has certain rigid and elastic range is limited, so it is still very big to be delivered to the vibration of outlet pipe during internal combustion engine, and corrugated expansion joint self also can break because of long-time vibration causes fatigue.
Summary of the invention
The technical problem that the present invention will solve provides the effective expansion pipe of a kind of I. C. engine exhaust, and compensation performance is good, and transmitting vibrations is little.
For solving the problems of the technologies described above; The effective expansion pipe of I. C. engine exhaust of the present invention comprises intubate and sleeve pipe, and intubate and sleeve pipe are the cylindrical tube that an end is provided with flange, and both mouths of pipe in opposite directions; Casing pipe sleeve is outside intubate; The outer wall of intubate is provided with at least one compression, is provided with compression ring in the compression, and the outer wall of intubate and the inwall of sleeve pipe are tightly connected through compression ring.
After having adopted above structure, at length direction, because intubate can freely be stretched in sleeve pipe; Compensation range is very big; At circumferencial direction, because the elasticity of compression ring also can well be compensated, and this expansion pipe is a split-type structural; Two ends only connect through compression ring, and the vibration of therefore transmitting is very little.
Compression ring on the intubate can be three roads.
Description of drawings
Do further explain below in conjunction with the accompanying drawing specific embodiments of the invention:
Fig. 1 is the structural representation of the effective expansion pipe of I. C. engine exhaust of the present invention.
Among the figure: 1 intubate, 2 compression rings, 3 sleeve pipes.
Embodiment
As shown in Figure 1, expansion pipe of the present invention comprises intubate and sleeve pipe, and intubate and sleeve pipe are the cylindrical tube that an end is provided with flange; Both mouths of pipe in opposite directions, casing pipe sleeve is outside intubate, the outer wall of intubate is provided with at least one compression; Be provided with compression ring in the compression; The quantity of compression ring and compression is preferably three roads, and the outer wall of intubate and the inwall of sleeve pipe are tightly connected through compression ring, and the flange end of intubate and sleeve pipe links to each other with machine relief opening and outlet pipe respectively.
During machine works, intubate can freely be stretched in sleeve pipe, and at circumferencial direction, because the elasticity of compression ring also can well be compensated, and this expansion pipe is split-type structural, and two ends only connect through compression ring, and the vibration of therefore transmitting is very little.
