Technical Field

The utility model relates to a high temperature fluid seal technical field especially relates to a high temperature is connected and is used grafting pipe.

Background

The high-temperature waste gas seal in the automobile industry mostly adopts a single-layer or multi-layer stainless steel seal gasket or other gaskets for flange connection sealing, or adopts an inserted structure to be matched with a seal ring for sealing, or adopts a welded corrugated pipe to be sealed through a V-shaped clamp.

The bolt flange connection sealing needs a large installation space, the limitation that the deformation problem caused by expansion of the connecting piece cannot be relieved exists, the whole structure is relatively complex, and the cost is high.

The plug-in structure is matched with the sealing ring for sealing, the sealing ring is relatively large in sealing relative leakage amount, particularly, the static leakage amount is overlarge, the material and the process of the design of the sealing ring are limited, and the large leakage amount always exists in the actual use process.

Use the welding bellows, seal through the V type clamp, can effectively solve sealed and inflation problem, but the technology is complicated, and the cost increases a lot relatively, and the installation needs certain space.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming that present high temperature waste gas seals the time problem more, reveals easily, and the installation is complicated simultaneously, increases the not enough of staff's work, and the pipe of pegging graft for high temperature connection that proposes.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a high temperature is connected with grafting pipe, includes two exhaust gas connecting pipes, all be equipped with the opening on the both ends lateral wall in two exhaust gas connecting pipes, be equipped with sealed the pad jointly in four openings, be equipped with the bushing pipe in the sealed pad, sealed pad is saddle type structure, sealed both ends of filling up are the turn-ups design.

The sealing gasket is in a special sealing gasket structure designed by extrusion fit of the two waste gas connecting pipes, so that the axial and radial sealing of the joint is realized, the sealing problem when the expansion amount of the high-temperature part is large is solved, and the problems of process complexity, assembly complexity and high cost are avoided

Preferably, two rivets are arranged on the sealing pad in a penetrating manner, and the lower ends of the two rivets extend into the lining pipe.

The rivet fixes the sealing gasket and the liner tube firmly.

Preferably, the liner tube and the sealing gasket flanging are axially designed with a gap, and the gap is designed to be 0-3 mm.

The gap is 0-3mm, so that the leakage of waste gas can be prevented, and the sealing effect of the sealing gasket is ensured.

Preferably, the flanges of the sealing gasket are connected with flange waves.

The flanging wave is convenient for the two waste gas connecting pipes to extrude the flanging of the sealing gasket, so that good sealing performance is formed.

Preferably, the sealing gasket is made of heat-resistant stainless steel material, and the thickness of the sealing gasket is 0.2-1.0 mm.

Preferably, both ends of the liner tube are chamfered.

The chamfer is convenient to install the liner tube in the sealing gasket, and the assembly time is shortened.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the device has the advantages of small installation space, compact space, large supplementary expansion amount, good sealing performance, functions of the corrugated pipe and the sealing gasket, and avoidance of the problems of process complexity, assembly complexity and high cost;

2. the saddle-shaped sealing gasket realizes axial and radial sealing of a joint by the aid of a special sealing gasket structure in extrusion fit of two waste gas connecting pipes, solves the problem of sealing when the expansion amount of a high-temperature part is large, and can be used for sealing of a structure with a relatively small sealing space.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1-5, a splicing pipe for high temperature connection, comprising two exhaust gas connecting pipes 2, wherein the side walls of two ends of each exhaust gas connecting pipe 2 are provided with openings 4, a sealing gasket 1 is jointly arranged in each opening 4, the sealing gasket 1 is fixed by the arrangement of the four openings 4, the flanges on two sides of the sealing gasket 1 can be extruded at the same time to prevent radial leakage, the sealing gasket 1 is made of heat-resistant stainless steel material, the thickness of the sealing gasket 1 is 0.2-1.0mm, a liner pipe 5 is arranged in the sealing gasket 1, two ends of the liner pipe 5 are chamfers, namely two inner side holes of the liner pipe 5, the outer side of the liner pipe 5 is processed by a processing type, the liner pipe 5 is conveniently and fixedly assembled in the sealing gasket 1, the processing by workers is convenient, two rivets 6 are arranged on the sealing gasket 1 in a penetrating manner, when the two fixing is not firm, the fixing can also be carried out by taking the circumference of the sealing gasket 1 as the center, the lower ends of the two rivets 6 extend into the liner pipe 5, the sealing gasket 1 is of a saddle-shaped structure, the saddle-shaped structure is 0.4-1.2mm in height coverage, the two ends of the sealing gasket 1 are designed to be turned over, a gap is axially designed between the liner tube 5 and the turned edge of the sealing gasket 1, the gap is designed to be 0-3mm, the gap is 0-3mm, the leakage of waste gas can be prevented, the sealing effect of the sealing gasket 1 is ensured, the turned edge of the sealing gasket 1 is connected with the turned edge wave 3, the turned edge wave 3 is convenient for the two waste gas connecting tubes 2 to extrude the turned edge of the sealing gasket 1, good sealing performance is formed, the supplement expansion amount of the sealing gasket 1 is large, the sealing performance is good, and the functions of a corrugated pipe and the sealing gasket are achieved.
