[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3 The present invention provides an implementation scheme: In the application process of modern turbochargers, the air inlet and outlet of the turbocharger are usually sealed with rubber rings. After the turbocharger is installed and closed, the internal environment cannot be observed. In addition, during use, the sealing ring needs to be replaced due to corrosion or contamination. At this stage, the turbocharger and the engine and the exhaust pipe of the engine need to be completely disassembled. When disassembling and replacing, it is also necessary to reach into the pipe opening to find the sealing ring, which is inconvenient.

[0022] According to the instruction manual Figure 1-3 It can be seen that in response to the above problems, the present application discloses a pipeline sealing structure of a turbocharger, including a turbocharger housing, the turbocharger housing adopts a volute shape, and is provided with at least one air inlet and an air outlet and at least one exhaust gas inlet and an exhaust gas exhaust port on the turbocharger housing, wherein the exhaust gas inlet of the turbocharger housing is connected to the exhaust port of the engine, the exhaust gas generated by the engine drives the active turbine to rotate, and the active turbine drives the intake turbine to rotate through a rod transmission, and the intake pressure of the air inlet is increased by the rotation of the intake turbine, and the high-pressure air entering the air inlet passes through the turbocharger and enters the intake chamber of the engine from the air outlet to be mixed with fuel or gas, and then enters the combustion chamber for combustion, wherein the air outlet and the waste inlet are connected to the engine, and an integrated connection sealing structure is provided on the air outlet and the exhaust gas inlet;

[0023] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned integrated connection sealing structure includes a sealing rubber ring 1, which is a plate with a circular ring structure. One side of the sealing rubber ring 1 is connected to a mounting seat 2, and the mounting seat 2 is provided with a plurality of connection holes 3 in a ring array. A plurality of connection holes 3 are assembled with a plurality of connection bolts 4;

[0024] In the specific implementation process, one side of the sealing rubber ring 1 contacts the inner side of the air inlet, and the outer sealing ring 5 is used to seal the outer side of the air inlet. The outer sealing ring 5 and the sealing rubber ring 1 are coaxially arranged on the mounting seat 2, and then a number of connecting bolts 4 are used to penetrate a number of connecting holes 3 and simultaneously connect to the engine and the turbocharger housing, thereby fixing the mounting seat 2 in position, and the pulling effect of the connecting bolts 4 is used to make the connection between the engine and the turbocharger housing tight.

[0025] According to the instruction manual Figure 1-3 It can be seen that the sealing rubber ring 1 and the mounting seat 2 are integrally formed, and the mounting seat 2 is provided with an outer sealing ring 5, which is coaxially arranged with the sealing rubber ring 1 and is sleeved on the air outlet or the exhaust inlet;

[0026] In the specific implementation process, the center of the mounting seat 2 is provided with a through groove 6, which matches the inner diameter of the sealing rubber ring 1. The middle of the through groove 6 is for gas to pass through. Since the sealing rubber ring 1 and the outer sealing ring 5 are concentric ring structures that wrap the air outlet or exhaust gas inlet of the turbocharger housing, the outer sealing ring 5 is exposed to the air outlet and exhaust gas inlet of the turbocharger housing, so it is easy to observe whether the air outlet or exhaust gas inlet position is sealed.

[0027] According to the instruction manual Figure 1-3 It can be seen that a rotation groove 7 is provided on the outer side of the mounting seat 2, and an assembly seat 8 is sleeved on the rotation groove 7. The assembly seat 8 is an annular structure and transitionally cooperates with the rotation groove 7. An operating panel 9 extends from one side of the assembly seat 8.

[0028] During the specific implementation process, the assembly seat 8 is installed through the rotating groove 7. While the assembly seat 8 is installed with the rotating groove 7, the assembly seat 8 can drive the operating panel 9 to rotate to an angle suitable for manual operation, and then the operating panel 9 can be used to facilitate the placement of the mounting seat 2.

[0029] As a preferred solution, further, a plurality of connecting rods are provided on the outer periphery of the air outlet and the exhaust inlet of the turbocharger housing. The plurality of connecting rods are inserted into the plurality of connecting holes 3 and are connected with the plurality of connecting bolts 4 by reverse pull.

[0030] As a preferred solution, further, several connecting card holes 3 are several cylindrical through holes and match the diameters of several connecting rods. Several connecting card holes 3 are symmetrically provided with bevels on both sides, and the bevel setting plays a guiding role during the installation of the connecting rods.

[0031] As a preferred solution, further, the outer sealing ring 5 is an annular structural plate and the end of the outer sealing ring 5 is an outward-inclined slope structure. The outward-inclined slope structure of the outer sealing ring 5 can ensure that the dirt falls on the outer sealing ring 5 and is diverted outward to avoid flowing into the side of the sealing rubber ring 1.

[0032] As a preferred solution, further, a bearing insert ring 10 is provided on the back side of the outer sealing ring 5 on the mounting seat 2. The outer edge of the bearing insert ring 10 is a beveled structure, and the through groove 6 passes through the bearing insert ring 10. A socket is provided on one side of the engine corresponding to the bearing insert ring 10, which facilitates the early installation of the mounting seat 2 on the engine.

[0033] From the above, it can be seen that the pipeline sealing structure of the turbocharger is simple in structure and easy to install. It adopts an inner and outer double-layer sealing structure. The double-layer sealing adopts a coaxial arrangement to wrap the air outlet and the exhaust gas inlet of the turbocharger housing, so that the turbocharger is tightly connected to the engine. At the same time, due to the presence of the external sealing ring 5 placed on the outside, it can be clearly observed whether the air outlet or exhaust gas inlet of the turbocharger is sealed. In addition, the sealing rubber ring 1 can be quickly removed through the assembly seat 8 during disassembly and replacement, which is convenient for disassembly and maintenance.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
