Abstract
The utility model provides a circulating purifying pipe for exhaust gas of a diesel engine. The circulating purifying pipe comprises a pipe body, a connecting bend (3) and two horn mouth core plugs (4), wherein the horn mouth core plugs (4) are located at two ends of the pipe body; the pipe body is integrally formed by two sections of round pipes (1) and a corrugated pipe (2) between the two sections of the round pipes (1) and is welded with the connecting bend (3), the connecting bend (3) is welded with the horn mouth core plugs (4), and the pipe body and the horn mouth core plugs (4) are integrally formed; an inner cavity of the connecting bend (3) is an arc surface in smooth transition, the inner diameter of the connecting bend (3) is equal to the inner diameters of the round pipes (1), and a sealing oblique plane (5) is arranged on the inner side wall of each horn mouth core plug (4). The circulating purifying pipe has the beneficial effects of reliable sealing performance, difficulty in leakage, smooth airflow, good vibration resistance and no vibration noise.
Description
Technical field
The utility model relates to automotive engine component technical field, is specifically related to a kind of diesel engine exhaust circularly purifying pipe.
Background technique
People pay close attention to day by day and strengthen automobile product environmental issue, and energy-saving and emission-reduction continue consumption reduction, are large purport targets.Diesel engine exhaust circularly purifying pipe, effect is that engine exhaust is again reclaimed and enters firing chamber and burning again together with fresh air.The composition of this pipeline generally comprises body, connecting bend, horn mouth plug three parts, in use due to for a long time in vibrational state, pipeline is easily revealed, and vibration noise is large, air-flow is not steady, affects Integral automobile performance and driving comfort.
Model utility content
Technical problem to be solved in the utility model is for above the deficiencies in the prior art, provide a kind of sealability reliable, be difficult for revealing, air-flow is steady, anti-seismic performance good, the diesel engine exhaust circularly purifying pipe of friction noise.
For addressing the above problem, the utility model provides a kind of diesel engine exhaust circularly purifying pipe, this purification pipe comprises body, connecting bend and is positioned at two horn mouth plugs at two ends, described body is made of one piece by two sections of pipes bellows middle with being positioned at two sections of pipes, the inner chamber of described connecting bend is the internal diameter that the arc surface of transitions smooth and the internal diameter of connecting bend equal pipe, and the madial wall of described horn mouth plug is provided with a sealing inclined-plane.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
(1) the utility model pipe structure is one-body molded and one-body molded with the horn mouth plug of body end, body and connecting bend welding, the horn mouth plug welding of connecting bend and its end, the weld of pipe is seamless, the whole one of accessory, this makes whole purification pipe body structure firm, intensity is high, shock resistance is strong, anti-fatigue performance good, after testing, the utility model purification pipe yield stress can reach 230Mpamin, tensile strength and can reach that 540-750Mpa, elongation at break can reach 45%, hardness can reach HRB 80-90;
(2) in the middle of body, adopt one section of bellows, make impact resistance, the flexural fatigue excellence of purification pipe, can under vibration frequency, use for a long time and keep friction noise, reliable performance;
(3) arc surface that connecting bend inner chamber is transitions smooth, the internal diameter of connecting bend equal the internal diameter of pipe, i.e. identical, the transitions smooth of whole purification pipe interior internal diameter, and this is conducive to reduce noise, and guarantees that air flow rate is steady;
(4) at horn mouth plug madial wall, sealing inclined-plane is set, use the horn mouth plug with tapering to connect miscellaneous part, this design is very convenient when assembling, directly with clip, carries out periphery and fixes, and taper fit is also very reliable aspect sealing, be not easy to reveal.
As preferably, described body, connecting bend, horn mouth plug are made by stainless steel material.Adopt high performance stainless steel, Kang Zhen ﹑ corrosion resistance Qiang ﹑ is high temperature resistant, can in the situation that environment is severe, use for a long time, and the life-span is long.
As preferably, the diameter of described pipe is 40-50mm, and thickness is 0.5-1mm, 0.5-0.8mm more preferably.Adopt large diameter body, coordinate suitable thickness, the flow that makes this purification pipe is larger, air-flow is more stable, and Safety performance is higher.
Accompanying drawing explanation
Shown in Fig. 1 is the structural representation of the utility model diesel engine exhaust circularly purifying pipe;
Shown in Fig. 2 is the sectional view of the horn mouth plug of the utility model diesel engine exhaust circularly purifying pipe.Wherein: 1, pipe; 2, bellows; 3, connecting bend; 4, horn mouth plug; 5, sealing inclined-plane.
Embodiment
Below in conjunction with embodiment, the present invention is further described in detail.Be noted that following illustrating is all exemplary, be intended to the invention provides further instruction.Except as otherwise noted, all Science and Technology terms that the present invention uses have the identical meanings of conventionally understanding with the technical field of the invention personnel.
As shown in Figure 1, 2, the utility model diesel engine exhaust circularly purifying pipe comprises body, connecting bend 3 and is positioned at two horn mouth plugs 4 at two ends, be that its order of connection is horn mouth plug 4, body, connecting bend 3, horn mouth plug 4 by end to end, wherein between horn mouth plug 4 and body, being formed in one, is welding between body and connecting bend 3, between connecting bend 3 and horn mouth plug 4.Described body is made of one piece by two sections of pipes 1 and the bellows 2 that is positioned at two sections of pipes, 1 centre.The inner chamber of described connecting bend 3 is the internal diameter that the arc surface of transitions smooth and the internal diameter of connecting bend 3 equal pipe 1.
The madial wall of described horn mouth plug 4 is provided with a sealing inclined-plane 5, in the time of concrete connection, with the parts of its assembling as vehicle-exhaust exhaust pipe or exhaust gas circulating device airflow line, insert horn mouth plug 4 inside and end and tightly prop up sealing inclined-plane 5, then use clip to be fixed and to clamp in horn mouth plug 4 peripheries, the sealing between horn mouth plug 4 and assembly parts can be improved greatly.
Described body, connecting bend 3, horn mouth plug 4 are made by stainless steel material.The diameter of described pipe 1 is 40-50mm, and thickness is 0.5-0.8mm.
Above embodiment is to explanation of the present utility model and further explains, rather than to restriction of the present utility model, any modification of doing in interest field of the present utility model, all falls into protection domain of the present utility model.
