Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.

Shown in Fig. 1 and Fig. 2, the supercharging liner 1 of this utility model embodiment, it includes bushing pipe 11 ringwise And the inner core 12 being filled in bushing pipe 11, being made up of exotic material；Supercharging liner 1 of the present utility model may be mounted at The junction of two flanges, makes its cross section that elastic deformation to occur by flange extruding supercharging liner 1, so that supercharging seals The faying face of liner 1 and two flanges forms linear sealing, to ensure the reliability that the junction of two flanges seals.

Continuing referring to shown in Fig. 1 and Fig. 2, bushing pipe 11 can be used refractory metal sheet to be rolled by rolling technology and form, The first relative overlap edge 111 and second overlap edge 112 of sheet metal mutually overlap after rolling, the first overlap edge The outer wall of 111 abuts on the inwall of the second overlap edge 112, makes bushing pipe 11 cross section generally circular or oval, such section The bushing pipe 11 of face shape can have preferable load capacity when pressurized.

When bushing pipe 11 is squeezed, the first overlap edge 111 and the second overlap edge 112 can make bushing pipe 11 with relative movement Can be relatively easy to deform, the cross section making bushing pipe 11 is flattening, so that bushing pipe 11 is connect by line with contacting of flange Touch and be converted into face contact, to obtain preferable sealing effectiveness；And inner core 12 provides good support to bushing pipe 11, it is unlikely to bushing pipe 11 deformation are excessively serious and make bushing pipe 11 impaired, cause seal failure；When the pressure on bushing pipe 11 is unloaded, bushing pipe 11 is by bullet Property restoring force effect restore to the original state.

Continuing referring to shown in Fig. 1, the shape of supercharging liner 1 can be annular, oval ring, square or polygon Shape, with adaptive difform flange；Certainly, the shape of supercharging liner 1 is not limited to above-mentioned four kinds of shapes, and it also can root Other polymorphic structure is used adaptively according to the actual application scenarios of flange.

Shown in Fig. 3 and Fig. 4, this utility model embodiment additionally provides a kind of black box, and it includes above-mentioned enforcement Supercharging liner 1, first flange 2 of example and the second flange 3；Wherein, the end face of the first flange 2 offers annular groove 21, supercharging liner 1 is socketed in annular groove 21, and the degree of depth of annular groove 21 is less than the bushing pipe 11 of supercharging liner 1 Caliber, when the second flange 3 and the first flange 2 corresponding matching are fastenedly connected, the end that the second flange 3 coordinates with the first flange 2 Extruding supercharging liner 1 is made it be deformed by face, and the part making supercharging liner 1 be exposed at annular groove 21 is pressed into In annular groove 21, to be substantially filled with the space of full annular groove 21, make supercharging liner 1, annular groove 21 and second Flange 3 forms good linear sealing, thus simplifies the assembly technology of black box.

Shown in Fig. 3 and Fig. 4, the sidewall of the first flange 2 and the second flange 3 is equipped with multiple engaging lug 4 (second The engaging lug of flange 3 is not shown), engaging lug 4 is provided with through hole 5, the engaging lug on the second flange 3 and the company of the first flange 2 Lug 4 corresponding matching, and pass through screw lock.The purpose arranging annular groove 21 on the first flange 2 is convenient adaptive supercharging Liner 1, to improve the versatility of supercharging liner 1, say, that can consider the first flange 2 and second The restriction of the shape factors such as the quantity of the engaging lug 4 on flange 3 and the middle opening of position and flange, as long as the first flange 2 End face can possess the condition offering annular groove 21, and therefore, the black box of this utility model embodiment also can simplify First flange 2 and the mounting structure of the second flange 3, reduces the first flange 2 and volume of the second flange 3.

As shown in Figure 4, in this figure, for convenience of explanation, supercharging liner 1 and annular groove 21 are respectively shown half, Wherein, annular groove 21 can be annular, and supercharging liner 1 is preferably ellipse, and the benefit so designed is, when ellipse When circular supercharging liner 1 is socketed on the annular groove 21 of annular, owing to the two is the most variant, supercharging seals Liner 1 is limited to the shape of annular groove 21, and deforms upon so that supercharging liner 1 there is restorable trend and Buckling in annular groove 21, such that it is able to prevent black box when assembling, supercharging liner 1 takes off from annular groove 21 Fall.

Black box in above example can be located at the volute of turbocharger and the junction of catalyst converter, or, It is located at the volute of turbocharger and the junction of exhaust manifold, such that it is able to make the black box in the present embodiment play preferably Sealing effectiveness.

The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and replacement, these change Enter and replace and also should be regarded as protection domain of the present utility model.
