Abstract
The utility model discloses a kind of internal-combustion engine connecting tube with loose flange, comprise, hard tube, the straight length of hard tube or the pipe bent position of bending are formed with ripple; One end of hard tube is welded with fastening flange, and the other end of hard tube is set with loose flange, hard tube and loose flange Spielpassung, loose flange can along metal hard tube hard tube axially do Linear-moving simultaneously with metal hard tube for axle does circular-rotation.Beneficial effect is: loose flange can along metal hard tube axially move and with metal hard tube for axle rotates; Metal hard tube makes the internal-combustion engine connecting tube with axial and radial Automatic adjusument part, by the small and local plastic deformation of Automatic adjusument part in axis and radial direction, absorb thermal stress and cause deformation force and to shake generating portion damping, be suitable for the connection at each position of internal-combustion engine in cold and hot pipeline, stable performance, ensures gas ne-leakage.
Description
Technical field
The utility model relates to a kind of internal-combustion engine connecting tube, particularly relates to the internal-combustion engine connecting tube with loose flange on a kind of applicable automobile pipeline.
Background technique
Existing internal-combustion engine connects hard tube and adopts common steel tube (main material is stainless steel or carbon steel), after brake forming, for installing flange or other joint of connection in two ends soldering, tube bender bend pipe has the defect of front and back slippage, make plumbing dimensions, positional accuracy lower, affect efficiency of assembling, also affect the working life of other coupling.The pipeline most time of internal-combustion engine works under the cold alternation of heat and vibration simultaneously, and operating environment is severe, and the shake that thermal stress and vibration source produce also has a strong impact on the life-span of pipe fitting on pipeline.
Summary of the invention
Technical problem to be solved in the utility model is, provide one can along metal hard tube axially move and with metal hard tube for axle rotates, and be suitable for the internal-combustion engine internal-combustion engine connecting tube with loose flange that each position connects in cold and hot pipeline.
The technological scheme that the utility model adopts is: a kind of internal-combustion engine connecting tube with loose flange, comprises, hard tube, and the straight length of described hard tube or the pipe bent position of bending are formed with ripple; One end of described hard tube is welded with fastening flange, and the other end of hard tube is set with loose flange, hard tube and loose flange Spielpassung, described loose flange can along metal hard tube hard tube axially do Linear-moving simultaneously with metal hard tube for axle does circular-rotation.
The hard tube termination of installing described loose flange side is formed pulls limit, and restraint flange is deviate from and the pipe fitting that docks with it forms sealing surface.
Described fastening flange and outside coupling plane sealing; Loose flange and outside coupling gasket type endless belt seal.
The material of described fastening flange, hard tube and conic connector of giving vent to anger is stainless steel or straight carbon steel.
The beneficial effects of the utility model are: loose flange can along metal hard tube axially move and with metal hard tube for axle rotates; Metal hard tube makes the internal-combustion engine connecting tube with axial and radial Automatic adjusument part, by the small and local plastic deformation of Automatic adjusument part in axis and radial direction, absorb thermal stress and cause deformation force and to shake generating portion damping, be suitable for the connection at each position of internal-combustion engine in cold and hot pipeline, stable performance, ensures gas ne-leakage.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view that the utility model is provided with the internal-combustion engine connecting tube of loose flange.
In figure:
10. fastening flange 20. hard tube 30. loose flange.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, the utility model, with the internal-combustion engine connecting tube of loose flange, comprises, hard tube 20, and hard tube 20 is path thick walled tube, and the described straight length of hard tube 20 or the pipe bent position of bending are formed with ripple 21; One end of described hard tube 20 is welded with fastening flange 10, loose flange 30 is arranged on another termination that metal hard tube makes the path thick-wall bend with cold and hot self-regulation part, make with metal hard tube inside it and be with the path thick-wall bend transition gap of Automatic adjusument part to coordinate, described loose flange 30 can along metal hard tube hard tube axially do Linear-moving simultaneously with metal hard tube for axle does circular-rotation.Hard tube 20 termination of installing described loose flange 30 side is formed pulls limit 22, and the effect of pulling limit is that restraint flange deviates from this pipe, is that the axle head of loose flange is spacing; Pull limit another effect be this pull limit to be connected with it adpting flange contact surface pairing formed sealing surface.Described fastening flange 10 and outside coupling plane sealing, loose flange 30 and outside coupling gasket type endless belt seal; The material of described fastening flange 10, hard tube 20 and conic connector 30 of giving vent to anger is stainless steel or straight carbon steel.
The internal-combustion engine connecting tube 20 that metal hard tube is made with axial and radial Automatic adjusument part moves towards to load in pipeline along the pipeline of motor general arrangement, after the mouth of pipe of fastening flange 10 flange-interface centering of giving vent to anger corresponding to engine pipelines, be tightened by bolts, after typhon mouth formula pulls limit connecting flange center hole corresponding to engine pipelines centering, the corresponding connecting flange of engine pipelines pressed close to by the movement loose flange 30 rotated in a circumferential direction that can axially move, it is worthy of note, ripple can move with hand, make the fastening flange of its termination or movable and other end coupling centering to be coupled, again can by loose flange can along metal hard tube axially move and with metal hard tube for axle rotates, realize locking with end coupling to be coupled, locking torque performs by GB, on a production line, use pneumatic or electric fixed-torque spanner assembling, swift and convenient to operate, because metal hard tube makes the internal-combustion engine connecting tube with axial and radial Automatic adjusument part, by the small and local plastic deformation of Automatic adjusument part in axis and radial direction, absorb thermal stress and cause deformation force and to shake generating portion damping, the connection of the working environment of the vibrations of adaptation internal-combustion engine pipeline, high pressure, hot environment and sealing, stable performance, ensures gas ne-leakage.
The utility model adapts to treat connection part position angle deviation for axle rotates with metal hard tube by axially moving along metal hard tube due to loose flange simultaneously, is convenient to assembling to neutralization locking; Improve assembly qualified rate and efficiency.And metallic hard pipe end pull limit can small part absorb two be connected flange contact surface formed gap and face angle differential seat angle.Add the accommodation of sealing surface, enhance sealing reliability.Metal hard tube is made with axial and radial Automatic adjusument part both by the small and local plastic deformation of corrugated portion in axis and radial direction, absorb the thermal distortion forces that thermal stress causes, again by the small and local plastic deformation of corrugated portion in axis and radial direction, to shake generating portion damping force, add the reliability that relevant connection club man is done, also extend the working life of each associated member.
