Description

Technical Field

[0001] The utility model relates to the technical field of flange plates, and particularly relates to a high-strength flange plate for a turbocharger. Background Technique

[0002] A turbocharger is actually an air compressor that increases the intake air volume by compressing air. It uses the inertia impulse of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber. The turbine drives the coaxial impeller, and the impeller presses the air sent by the air filter pipeline to supercharge it into the cylinder. This device is the flange plate for pipeline connection. The flange plate is a part that connects pipes to each other and is connected to the pipe end;

[0003] Flange plates are usually used in two groups in butt joint. Between them, they are connected and fixed by multiple groups of bolts, and the force is borne by applying force to multiple groups of bolts. If the bolts are bent, deformed or broken due to excessive force, it is easy to affect the use of the flange plate;

[0004] Therefore, a high-strength flange plate for a turbocharger is needed to solve the above problems. Content of the Utility Model
