Description

Valve plate main body

Technical Field

The utility model relates to an auto-parts technical field specifically is valve block main part.

Background

A turbocharger is an air compressor driven by a structure composed of two coaxial impellers using exhaust gas generated by the operation of an internal combustion engine, similar to the supercharger function, both increase the air flow into the engine or boiler, thereby improving the combustion efficiency, is commonly used in automobile engines, and utilizes the heat and flow of the exhaust gas, and the turbocharger with the bypass valve has simple, reliable and effective structure, therefore, a turbocharger with a bypass valve is generally used at present, and the turbocharger bypass valve is designed, mainly because the turbocharger is driven by the force of exhaust gas discharge, when the pressure at the outlet of the compressor is too high, the bypass valve can be automatically opened, so that part of exhaust gas directly enters the exhaust pipe without passing through the turbine, the rotating speed of the supercharger is reduced, the pressure at the outlet of the compressor is reduced, and the aims of improving the low-speed performance and avoiding the overhigh explosion pressure of the cylinder and the overspeed of the supercharger under the high-speed working condition are fulfilled.

However, in the turbocharger with the bypass valve actuator in the prior art, the valve plate generally passes through the rocker arm plate through the mounting column at the center of the valve plate and is favorable for nut fastening connection, when the turbocharger works, the actuator drives the rocker arm plate to drive the valve plate to overturn so that the bypass port opens for exhaust, therefore, when the valve plate is opened, the valve plate is in a deflection state, and further the air output at two sides of the valve is uneven, so that when an engine exhausts for pulse, the valve plate is easy to shake, and meanwhile, the valve plate is easy to rotate when shaking, and further the valve plate can be driven by the mounting column to rotate, so that the mounting column is loosened, the shaking and the rotation of the valve plate are aggravated, further, the abrasion between the valve plate and a connecting device of the valve plate is aggravated, the service life of the whole device is shortened, and meanwhile. To this end, we propose a valve plate body.
