Abstract
The utility model relates to a heavily block the exhaust system of car, specifically be a blast pipe is connected and seal structure who makes exhaust system have good sealing performance as far as possible, including preceding, back row trachea (1, 2), preceding blast pipe (1) tip has set firmly preceding round flange (3), back row trachea (2) tip has set firmly back round flange (4), the connection terminal surface of preceding round flange (3) is provided with flange (5) stretched into in back round flange (4), for the public law orchid, then back round flange (4) are the mother law orchid, sealed fill up (6) of installation between preceding, back round flange (3, 4), preceding, back round flange (3, 4) are outer through two semicircle clamp (7) connection. The utility model relates to a rationally, basically not changing lowest cost and not influencing under performance's the condition, making exhaust system possess good sealing performance as far as possible, it is simply convenient to assemble, has good market using value.
Description
Technical field
This utility model relates to the gas extraction system of heavy truck automobile, and a kind of exhaustor making gas extraction system have good seal performance as far as possible couples sealing structure.
Background technology
The waste gas produced when gas extraction system is to be worked by electromotor guides discharges, and reduces produced noise and EGT, cleaning of off-gas etc. during aerofluxus.Along with improving constantly of Abgasgesetz, require to improve the most therewith to the capacity of gas extraction system.Exhaustor connection place is frequently present of problem that is poorly sealed and that reveal.How in the case of ensureing that cost is minimum and not affecting serviceability, make gas extraction system have sealing property as far as possible, be the problem that have to solve.
In a word, the problems with that existing like product in use occurs: 1, existing exhaustor couples poor sealing, there is gas leak phenomenon.2, existing product weight is relatively big, and expensive.3, existing product structure is easily damaged clip.4, the problem that existing product exists assembling difficulty.
Summary of the invention
The purpose of this utility model is that providing a kind of exhaustor to couple seals structure, and this kind of exhaustor couples sealing structure and can be good at improving the sealing property of gas extraction system.
This utility model adopts the following technical scheme that realization:
A kind of exhaustor connects and seals structure, and including forward and backward exhaustor, described front exhaust pipe end is installed with front round flange, and described final vacuum tube end is installed with rear round flange；The connecting end surface of described front round flange is provided with the flange stretched in rear round flange, blue for public law；After then, round flange is that mother law is blue；Sealing gasket is installed between described forward and backward round flange；By two semicircle clamp connections outside described forward and backward round flange.
Preferably, the outside circumference of described forward and backward round flange respectively fall 20 ° of angles, then the cross sectional shape of semicircle clip is without base trapezoidal shape, front and rear row trachea better seal is linked together.
This utility model changes flange arrangement, and traditional square flange structure changes into using round flange structure, and 20 ° of angles, front and back coordinates and uses a male mother to coordinate, it is simple to assembling.Increase sealing gasket, use exotic material sealing gasket, improve its sealing property.Use semicircle V-type (without base trapezoidal shape) clip, with gas exhaust tube flange perfect cooperation, while reducing cost, more improve efficiency of assembling.
Compared with prior art have the advantage that as follows:
1, the present invention uses round flange, sealing gasket to add the structure of V-type clip, substantially increases sealing property.
2, using round flange structure, relatively square flange structure, significantly reduces weight.
3, use semi-circular V-type clip, while reducing cost, reduce fault rate.
This utility model is reasonable in design, in the case of not changing least cost and not affecting serviceability, makes gas extraction system have good sealing property as far as possible, assembles simple and convenient, has good market using value.
Accompanying drawing explanation
Fig. 1 represents connection overall schematic of the present utility model.
Fig. 2 represents the cross-sectional view of Fig. 1.
Fig. 3 represents the structural representation of before and after's round flange.
Fig. 4 represents the structural representation of semicircle clip.
Fig. 5 represents the structural representation of sealing gasket.
In figure, 1-front exhaust pipe, 2-heel row trachea, round flange before 3-, round flange after 4-, 5-flange, 6-sealing gasket, 7-semicircle clip.
Detailed description of the invention
Below in conjunction with the accompanying drawings specific embodiment of the utility model is described in detail.
A kind of exhaustor connects and seals structure, including forward and backward exhaustor 1,2.As it is shown on figure 3, described front exhaust pipe 1 end is installed with front round flange 3, described heel row trachea 2 end is installed with rear round flange 4；The connecting end surface of described front round flange 3 is provided with the flange 5 stretched in rear round flange 4, blue for public law；After then, round flange 4 is that mother law is blue.
During installation, as shown in Figure 1, 2, sealing gasket 6(is installed as shown in Figure 5 between described forward and backward round flange 3,4), sealing gasket 6 is positioned at outside the flange that public law is blue；Flange part blue for public law is fitted into female flange docking, and the most forward and backward round flange 3,4 is outer to be connected by two semicircle clips 7, and two common inclusions of semicircle clip are fastened by bolts after flange before and after living, and clip shape is as shown in Figure 5.And, the outside circumference of forward and backward round flange 3,4 respectively fall 20 ° of angles, the cross sectional shape of clip be without base trapezoidal shape, just will front and back flange fastening (as shown in Figure 2), front and back flange use one male one mother cooperation, it is simple to assemble.Front and back increase sealing gasket between flange, use exotic material sealing gasket, improve its sealing property.Use flange perfect cooperation before and after semicircle V-type (without base trapezoidal shape) clip, with exhaustor, while reducing cost, more improve efficiency of assembling.
Finally it should be noted that; above example is only in order to illustrate the technical solution of the utility model and unrestricted; although being described in detail with reference to this utility model embodiment; it will be understood by those within the art that; the technical solution of the utility model is modified or equivalent; without departure from the spirit and scope of the technical solution of the utility model, it all should be contained in claims of the present utility model.
