Detailed Description
In order to deepen the understanding of the present invention, we will make further details of the present invention with reference to the drawings, and this embodiment is only used to explain the present invention, and does not constitute a limitation to the protection scope of the present invention.
Fig. 1 to 3 show a specific embodiment of a turbocharger relief valve for improving sealing performance, which includes a valve cover 1, the valve cover 1 includes a connecting portion 11 and a sealing portion 12, the sealing portion 12 can be in sealing fit with a relief hole 21 of a volute 2, and further includes a rocker arm 3 and a valve cover positioning gasket 4, two ends of the rocker arm 3 are respectively provided with a valve cover positioning hole 31 and a rocker shaft 32, the connecting portion 11 is fixedly connected with the valve cover positioning hole 31, the rocker shaft 32 is movably connected to the volute 2, and the valve cover positioning gasket 4 is inserted into the connecting portion 11 and abuts against the upper surface of the rocker shaft 32.
Preferably, the valve further comprises a disk-shaped elastic sheet 5, and the disk-shaped elastic sheet 5 is arranged between the sealing part 12 of the valve cover 1 and the valve cover positioning hole 31 of the rocker arm 3. The volute casing 2 is provided with an annular lining hole 6, and the rocker arm shaft 32 penetrates through the lining hole 6. The elastic force of the disk-shaped elastic sheet 5 is 60-70N. The contact surface between the sealing part 12 and the air release hole 21 is in interference fit.
The specific working principle of the above embodiment is as follows:
when the turbocharger works, the exhaust gas in the air vent 21 of the volute 2 forms larger pressure, the valve cover 1 is responsible for maintaining the air pressure in the volute 2 within a certain range, when the pressure is overlarge, the valve cover 1 is opened to release redundant exhaust gas, and when the pressure is reduced, the valve cover 1 is closed. When the valve cover 1 needs to be opened, the rocker shaft 32 rotates to drive the sealing part 12 of the valve cover 1 to be separated from the air vent 21; when the valve cover 1 needs to be closed, the rocker shaft 32 rotates to drive the sealing part 12 of the valve cover 1 to be attached to the air vent 21, the butterfly-shaped elastic piece 5 is arranged between the valve cover 1 and the rocker arm 3, and the elastic value of the butterfly-shaped elastic piece 5 after being assembled is controlled to be 60-70N during assembly.
