Release valve device for reducing knocking noise of pressurizer valve

Abstract

The invention discloses a release valve device for reducing knocking noise of a pressurizer valve. The release valve device comprises a valve corresponding to a bypass valve hole in a turbine box. Thevalve is parallel with the plane where the top of the bypass valve hole is located and connected with one end of a rocker arm. The middle of the rocker arm is rotatably connected with a rotating pinassembly arranged on the turbine box, and the other end of the rocker arm is hinged to the front end of an actuator push rod. When the actuator push rod works, the rocker arm is driven to rotate around the rotating pin assembly, and furthermore, the valve is driven to rotate in the plane where the valve is located. By means of rotation of the valve, the valve can be staggered or coincide with thebypass valve hole, and thus, the switching-on or switching-off action of the release valve is achieved. According to the release valve device, the valve cannot collide with the wall of the bypass valve hole, and the knocking noise of the pressurizer release valve and the valve hole wall can be effectively reduced; meanwhile, the switching-on area of the valve can be controlled precisely so that the increased pressure can be controlled precisely.

Description

technical field [0001] The invention relates to the technical field of turbine boxes, in particular to a blow-off valve device for reducing the knocking sound of a supercharger valve. Background technique [0002] Turbocharging technology is a technology that converts the high-temperature, high-pressure exhaust energy of the engine into the effective work of the engine. On the one hand, this technology can improve engine power output; on the other hand, it can reduce fuel consumption; at the same time, due to the increase of intake pressure, it can improve fuel combustion to reduce the emission of harmful components such as CH and CO. In addition, this technology compensates for the reduced intake flow due to the increase in altitude and thinner air by increasing the intake pressure, which can slow down the decline in engine power due to the increase in altitude. Therefore, turbocharging technology will become the main development direction of future engines. [0003] At p...

[0004] However, the deflation valve with the above-mentioned structure is in contact with the deflation hole wall 4 when it is closed, and it is easy to generate a knocking sound. compressor performance

With the increasingly stringent emission regulations and the continuous improvement of the boost pressure ratio, the performance requirements of the supercharger are continuously improved. At the same time, the noise requirements of the passengers are also getting higher and higher. Therefore, it will be very meaningful to design a bleed valve that can not only reduce the knocking sound of the valve, but also realize the precise control of the bleed valve opening.
