Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a high-sealing valve plate of a bypass mechanism. Background Art

[0002] A turbocharger is an air compressor driven by a structure consisting of two coaxial impellers using the exhaust gas generated by the operation of an internal combustion engine. It has similar functions to a mechanical supercharger. Both can increase the air flow entering the internal combustion engine or boiler, thereby improving combustion efficiency. It is commonly used in automobile engines by utilizing the heat and flow of the exhaust gas. The turbocharger with a bypass valve has a simple structure, is reliable and effective, so the turbocharger with a bypass valve is currently widely used. The design of the turbocharger bypass valve is mainly because the turbocharger is driven by the power of exhaust gas discharge. When the compressor outlet pressure is too high, the bypass valve will automatically open, allowing part of the exhaust to enter the exhaust pipe directly without passing through the turbine, the turbocharger speed is reduced, and the compressor outlet pressure is reduced, thereby achieving the purpose of improving low-speed performance and avoiding excessive cylinder explosion pressure and supercharger overspeed under high-speed conditions.

[0003] In the prior art, the valve plate of a turbocharger with a bypass valve actuator generally passes through a rocker plate through a mounting column at its center and is fastened with a nut. However, when the turbocharger is working, its actuator drives the rocker plate to cause the valve plate to flip, so that the bypass port is opened for exhaust. After long-term use, the connection between the valve plate and the bypass port will become loose. Therefore, we propose a high-sealing valve plate of the bypass mechanism. Utility Model Content

[0006] Among them, the extrusion mechanism includes an extrusion plate fixedly connected to the middle part of the inner wall of the valve plate, the valve plate can fix the position of the extrusion plate, one end of the extrusion plate is fixedly connected to a clamping ring, the extrusion plate can fix the position of the clamping ring, one end of the clamping ring is fixedly connected to a dust cover, the clamping ring can fix the position of the dust plate.

[0007] Among them, a sealing ring is clamped on one side of the inner wall of the valve plate, the valve plate can fix the position of the sealing ring, and the sealing ring can seal the inside of the valve plate. A hole groove adapted to the sealing ring is opened on one side of the inner wall of the valve plate.

[0008] Among them, a connecting ring is sleeved on the inside of the valve plate, one end of the connecting ring is fixedly connected to the supercharger housing, and the supercharger housing can fix the position of the connecting ring; one side of the surface of the connecting ring is fixedly connected to a triangular plate, and the connecting ring can fix the position of the triangular plate.

[0009] Wherein, the inner diameter of the sealing ring is the same as the outer diameter of the connecting ring.

[0010] The sealing ring is made of rubber, and the thickness of the sealing ring at the non-tip end is 6 mm.

[0011] Wherein, one end of the valve plate is configured to have multiple continuous arcs.

[0012] The utility model has at least the following beneficial effects: through the arrangement of the valve plate, the extrusion mechanism and the triangular plate, the valve plate drives the extrusion mechanism to rotate when it rotates, and after the clamping ring contacts the triangular plate, it continues to receive the force transmitted by the valve plate and continues to move, and the connecting ring squeezes the clamping ring, and the clamping ring will move backward when squeezed.

One end of the valve plate 2 is set to multiple continuous arcs, and the multiple continuous arcs can reduce wind resistance. A sealing ring 4 is clamped on one side of the inner wall of the valve plate 2, and the valve plate 2 can fix the position of the sealing ring 4. The sealing ring 4 can seal the inside of the valve plate 2 to ensure that the gas does not leak. The sealing ring 4 is made of rubber, and the rubber material has strong adaptability. The non-tip thickness of the sealing ring 4 is 6mm, and one side of the inner wall of the valve plate 2 is opened There are holes and grooves that are compatible with the sealing ring 4, which can facilitate the installation of the sealing ring 4. Several extrusion mechanisms 3 are fixedly connected to the middle of the inner wall of the valve plate 2, and the valve plate 2 can fix the position of the extrusion mechanism 3. The extrusion mechanism 3 includes an extrusion plate 301 fixedly connected to the middle of the inner wall of the valve plate 2, and the valve plate 2 can fix the position of the extrusion plate 301. One end of the extrusion plate 301 is fixedly connected to a snap ring 302, and the extrusion plate 301 can fix the position of the snap ring 302. The extrusion plate 301 is similar to a spring, and the snap ring 302 moves inward to squeeze the extrusion plate 301.

[0021] Example 2

[0022] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that a connecting ring 5 is sleeved inside the valve plate 2, and the connecting ring 5 can facilitate the installation of the triangular plate 7. One end of the connecting ring 5 is fixedly connected to the supercharger housing 6, and the supercharger housing 6 can fix the position of the connecting ring 5 to ensure that the position of the connecting ring 5 will not change. One side of the surface of the connecting ring 5 is fixedly connected to the triangular plate 7, and the connecting ring 5 can fix the position of the triangular plate 7. The clamping ring 302 is clamped with the triangular plate 7 to fix the valve plate 2 on the surface of the connecting ring 5.
