Problems solved by technology

[0003] In the prior art, the sealing effect of the valve body is not good. Specifically, there is an air leakage phenomenon between the valve body and the cover plate, and there is an air leakage phenomenon between the valve body and the insert piece, which will affect the turbine during use. Supercharging effect, which in turn affects the performance and power of the engine
At the same time, the fixed guide post in the valve body is welded by two materials. After a long time of use, the fixed guide post will be deformed, affecting the movement of the moving iron core, affecting the response time of the valve body, and affecting the performance of the valve body.

Abstract

The invention discloses a high-performance electric-control bypass valve for a turbocharger. The high-performance electric-control bypass valve comprises a valve body and a valve body sealing member arranged at the bottom of the valve body. The bypass valve is characterized in that an outlet is arranged at the bottom of the valve body, the valve body sealing member is movably arranged in the outlet, a columnar cover plate is arranged on the outlet, multiple sealing rings are arranged at a joint of the columnar cover plate and the valve body for sealing, and a stainless steel guide column integrally formed with the valve body is arranged in the valve body. Sealing effect of the valve body is improved, service life of the valve body is prolonged, response time of the valve body is increased,turbocharging quality is ensured, and performance and power of an engine are guaranteed.

Description

technical field [0001] The invention relates to a turbocharger, in particular to a high-performance electronically controlled bypass valve for the turbocharger. Background technique [0002] In order to respond to the policy of energy saving, emission reduction, environmental protection and low carbon, many cars are equipped with turbochargers. Among them, in order to protect the engine and turbine, a pressure relief valve is generally provided for protection. When the electronically controlled bypass valve is used, the bypass valve is generally energized, and the magnetic field generated by the bypass valve is used to make the moving iron core drive the sealing mechanism to rise. When the power is not energized, the moving iron core and the sealing mechanism are driven down by the spring , so that the sealing mechanism can reciprocate up and down with the moving iron core to realize pressure relief and exhaust. [0003] In the prior art, the sealing effect of the valve bo...
