Turbocharger deflation valve control device

Abstract

The invention discloses a turbocharger deflation valve control device which solves the problem that opening degree of an existing supercharger deflation valve is fixed or can not be continuously adjusted. The turbocharger deflation valve control device comprises an air inflow control valve (2), a pressure stabilizing tank (3), an air outflow control valve (6), an equal-diameter tee joint pipe connector (7), an outflow air pressure gauge (8) and a bypass valve (13). The left end of the air inflow control valve (2) is connected with a high pressure air source pipeline, the right end of the air inflow control valve (2) is connected with the left end of the pressure stabilizing tank (3), the right end of the pressure stabilizing tank (3) is connected with a pipeline at the left end of the air outflow control valve (6), an air supply pressure gauge (4) is connected on a pipeline between the pressure stabilizing tank (3) and the air outflow control valve (6), the right end of the air outflow control valve (6) is connected with a connector at the left end of the equal-diameter tee joint pipe connector (7), the right end of the equal-diameter tee joint pipe connector (7) is connected with a pipeline of a turbocharger deflation valve controller (15), and the lower end of the equal-diameter tee joint pipe connector (7) is connected with a pipeline of the bypass valve (13).

Description

technical field [0001] The invention relates to a device applied in the technical field of turbochargers of internal combustion engines, more precisely, the invention relates to a control device for a blow-off valve of a turbocharger. Background technique [0002] Exhaust gas turbocharging is a key technology of internal combustion engines, especially widely used in diesel engines. With the increasingly stringent emission regulations, improving the performance of turbochargers is one of the necessary measures to improve the performance and emissions of internal combustion engines. Now Many superchargers have internal bleed valves or bypass valves to adjust and control the flow of exhaust gas into the turbine, as shown in the drawings in the manual figure 2 Shown is a typical construction of a turbocharger with a bleed valve. The working principle of the turbocharger purge valve is as follows: when the boost pressure in the engine intake pipe 17 reaches a certain limit, the ...
