Abstract

The utility model provides a gas pipe for the intake and the exhaust of motor vehicles, which are pipe fittings molded by the bending of steel pipes.Both the wall thickness of the steel pipe and the size of the caliber are not limited.The two openings at the two ends of the pipe fittings are self-equipped with seal heads integrally formed with the pipe fittings.Since the seal head is integrally formed with the integral pipe fittings, the bearing direction of the steel pipe and the property of expending with heat and contracting with cold can be fully utilized during the practical application process.Therefore, the tensile strength is greatly increased.The appearance of the gas pipe is aesthetic, clean and smooth without weld seams.The production process is simplified and the cost is low.

Description

The tracheae that is used for the Motor Vehicle inlet and outlet

Technical field

The utility model relates to the tracheae that is used for the Motor Vehicle inlet and outlet.

Background technique

The present tracheae that is used for the Motor Vehicle inlet and outlet, as shown in Figure 1, after pipe fitting 2 bendings, pipe fitting end face interface and an end socket 1 are welded as a whole by circumferential weld 3, combine with flange then, finish Motor Vehicle inlet and outlet function of use.Pipe fitting after this gang welding, the production process complexity, technology is loaded down with trivial details, the investment of equipment, mould is big, cost of production is high, tensile strength is poor, weld defects is outstanding, occurs easily that weld seam is thin, to weld pore many, and tightness is poor, in use difficult installation, weld seam ftracture easily, cause gas leakage, the maintenance rate height, the after sales service expense is high.

Summary of the invention

The tracheae complex procedures, cost of production height, the intensity and toughness that are used for the Motor Vehicle inlet and outlet at present are poor in order to solve, easily gas leakage, shortcoming that maintenance rate is high, the utility model proposes a kind of Motor Vehicle air inlet and exhaust piper.

For this reason, the technical solution of the utility model is: being used for the tracheae of Motor Vehicle inlet and outlet, is the pipe fitting that adopts the tube bending moulding, and it is characterized in that: the wall thickness of steel pipe is not limit, and the caliber size is not limit, and the two-port of pipe fitting self has integrally formed end socket.

Beneficial effect: because end socket is integrally formed with pipe fitting, can make full use of being subjected to force direction and expanding with heat and contract with cold of steel pipe self in actual use, improve tensile strength greatly, outward appearance does not have weld seam, and is attractive in appearance, bright and clean, level and smooth.Production process is few, and cost is low.

Embodiment

As shown in Figure 2, being used for the tracheae of Motor Vehicle inlet and outlet, is the pipe fitting 4 that adopts the tube bending moulding, and the wall thickness of pipe fitting 4 is not limit, and the caliber size is not limit, and the two-port of pipe fitting 4 self has integrally formed end socket 5.

As shown in Figure 3, the structure of end socket 5 is: the port of pipe fitting 4 is formed with the mouth 6 that expands, and inwardly back bending has one deck bending 8, and there is flange 9 outer of bending 8, and it is gapped between mouth 6 and the bending 8 to expand.Bending 8 is the transition of fillet nature with the transitional surface of the mouth 6 that expands.

As shown in Figure 4, the structure of end socket 5 with shown in Figure 3 different is, expand mouthfuls 6 and bending 8 between do not have the gap.

As shown in Figure 5, the structure of end socket 5 is: the port of pipe fitting 4 is formed with the mouth 6 that expands, and inwardly back bending has one deck bending 10, and the outer of bending 10 is without turn-ups, and expanding does not have the gap between mouth 6 and the bending 10.Bending 10 is the transition of fillet nature with the transitional surface of the mouth 6 that expands.

As shown in Figure 6, the structure of end socket 5 is: the port of pipe fitting 4 is formed with the mouth that expands, and bloated mouth is configured as flange 11, and inwardly back bending has one deck bending 12, and the center line of the end face of flange 11 and pipe fitting 4 is 90 ° of angles, and is gapped between bending 12 and the flange 11.Also can be very close to each other between bending 12 shown in Figure 6 and the flange 11.Bending 12 is the transition of fillet nature with the transitional surface of flange 11.

As shown in Figure 7, the structure of end socket 5 is: the port of pipe fitting 4 is formed with the mouth 13 that expands, and inwardly back bending has one deck bending 14, and bending 14 is also extended axle journal 15, and is gapped between bending 14 and the bloated mouth 13.Also can be very close to each other between bending 14 shown in Figure 7 and the bloated mouth 13, bending 14 is the natural transition of fillet with the transitional surface of the mouth 13 that expands.

As shown in Figure 8, the port of pipe fitting 4 is formed with the mouth 16 that expands, and does not have back bending.

Integrally formed end socket 5 does not limit to and above-mentioned mode of execution, and its termination breathing, back bending face what arbitrarily, and the multiaspect back bending can be arranged, but breathing, back bending combination in any.As long as the two-port self at pipe fitting has integrally formed end socket, all should be in protection domain of the present utility model.

As shown in Figure 9, the tracheae that is used for the Motor Vehicle inlet and outlet can be formed by connecting by multiple tubing element, and the linkage structure of intermediate section two interfaces is: there is the mouth of expanding 19 pipe fitting 17 ends, and pipe fitting 17 passes through mouthful 19 sockets of expanding with pipe fitting 18.

As shown in figure 10, the tracheae that is used for the Motor Vehicle inlet and outlet can be formed by connecting by multiple tubing element, and the linkage structure of intermediate section two interfaces is: there is reducing 20 pipe fitting 17 ends, and pipe fitting 17 and pipe fitting 18 are by reducing 20 sockets.

Above-described bending has only one deck, and bending also can have multilayer.

More than, the transitional surface that relates to both can be round-corner transition, also can be chamfering transition or typing surface blending.Transitional surface comprises between bloated mouth and the pipe fitting, between bending and the bloated mouth, between flange and the bending.

The tracheae that is used for the Motor Vehicle inlet and outlet also can be a pipe fitting.
