Summary of the invention
Technical problem to be solved in the utility model is, provides one can axial and radial Automatic adjusument, is beneficial to the internal-combustion engine connecting tube that in cold and hot pipeline, each position connects.
The technological scheme that the utility model adopts is: a kind of internal-combustion engine connecting tube, comprises, hard tube, and the straight length of described hard tube is formed with ripple.
The suction port welded flange of described hard tube, the outer wall of the air outlet of hard tube welds conic connector.
Described hard tube is Detecting of Small Caliber Thick Pipes.
The material of described flange, hard tube and conic connector is stainless steel or straight carbon steel.
The termination of described flange and conic connector is locked connect with the coupling centering of end to be coupled respectively.
A kind of internal-combustion engine connecting tube, comprise, hard tube, the pipe bent position of the bending of described hard tube is formed with one group or two groups of ripples.
The suction port of described hard tube and air outlet welded flange respectively.
The beneficial effects of the utility model are: due to metal hard tube being formed with ripple, this ripple has axial and radial Automatic adjusument function, therefore, it is possible to small and local plastic deformation on adjustment hard tube, and absorb thermal stress and cause deformation force and to shake generating portion damping, metal hard tube is applicable to the connection at each position of internal-combustion engine in cold and hot pipeline, stable performance, ensures gas ne-leakage.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Embodiment 1, and as shown in Figure 1, the utility model internal-combustion engine connecting tube, comprises, hard tube 20, and hard tube 20 is Detecting of Small Caliber Thick Pipes, and making at the straight length of hard tube 20 can at the self-regulating ripple 21 of cold and hot; The suction port welded flange 10 of hard tube 20, the outer wall of the air outlet of hard tube 20 is welded with conic connector 30; Flange 10 and conic connector 30 form external connecting joint, and external connecting joint is locked and connected with the coupling centering of end to be coupled, that is, flange and outside coupling plane sealing respectively, and conic connector and the little endless belt of the outside coupling conical surface seal; The material of described flange 10, hard tube 20 and conic connector 30 is stainless steel or straight carbon steel.
Metal hard tube straight length make with axial and radial Automatic adjusument part internal-combustion engine connecting tube when mounted, the internal-combustion engine of axial and radial Automatic adjusument part is connected hard tube and moves towards to load in pipeline along the pipeline of motor general arrangement, the mouth of pipe the give vent to anger flange-interface corresponding to engine pipelines of flange 10 manually regulates ripple, after ensureing centering, be tightened by bolts, conic connector 30 manually regulates ripple at intake interface corresponding to engine pipelines, after ensureing centering, with locked clip device; Locking torque performs by GB, on a production line, use pneumatic or electric fixed-torque spanner assembling, swift and convenient to operate, because straight length band is axially connected hard tube with the internal-combustion engine of 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.
Embodiment 2, and as shown in Figure 2, the utility model internal-combustion engine connecting tube, comprises, hard tube 20, and the pipe bent position of the bending of described hard tube 20 is formed with one group or two groups of ripples 21; The suction port of described hard tube 20 and air outlet welded flange 10 respectively.Other structure and material is identical with embodiment 1, does not repeat them here.
Metal hard tube the band bend loss of pipe make with axial and radial Automatic adjusument part internal-combustion engine connecting tube when mounted, the internal-combustion engine connecting tube of 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 inlet flange 10 flange-interface centering of giving vent to anger corresponding to engine pipelines, be tightened by bolts, locking torque performs by GB.After flange of giving vent to anger inlet flange corresponding to engine pipelines and centering, be tightened by bolts; 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 internal-combustion engine connecting tube with axial and radial Automatic adjusument part at the band bend loss of pipe, many groups Automatic adjusument incorporating aspects on it, makes it install and regulates degrees of freedom more.Small and the local plastic deformation of its many group Automatic adjusument parts in axis and radial direction, absorb more thermal stress and cause deformation force and to shake generating portion damping, be applicable to the vibrations of internal-combustion engine pipeline, high pressure, the connection of working environment of hot environment and sealing widely.Many groups Automatic adjusument incorporating aspects makes this pipeline performance more stable, ensures gas ne-leakage
The utility model is when hot lower work, when passing into high heat (500 ° of about C) gas in hard tube, self adaption partially absorbs the size of hard tube thermal distortion and the small deformation amount of change in location generation, overcomes the distortional stress that hard tube produces its coupling in hot lower distortion; Improve working life and the size positions precision of the part that is connected.When working under normal conditions, Automatic adjusument part can ensure installation dimension positional accuracy; Absorb the stress that the vibration of its link produces, reduce the fatigue fracture impact that alternating stress produces coupling; Improve the working life of the fitting that is associated.Adopt Automatic adjusument part, the hard point of attachment in two ends, firmly, stable performance, is applicable to the cold and hot gas circuit hard tube of internal-combustion engine and connects in locking; Ensure gas ne-leakage, it is simple, convenient that this structure can realize assembling.
