Throttle valve sheet gap adjusting device and adjusting method thereof

Abstract

The invention discloses a throttle valve sheet gap adjusting device. The throttle valve sheet gap adjusting device comprises a bottom plate, a throttle valve positioning seat is fixed to the bottom plate, a plurality of positioning pins are fixed to the throttle valve positioning seat, a first valve sheet shaft fine adjustment mechanism and a second valve sheet shaft fine adjustment mechanism are fixed to the left side and the right side of the throttle valve positioning seat correspondingly, an electric cylinder and a sliding rail are fixed on a seat plate, a sliding seat is connected to the sliding rail in a sliding mode, a pressure sensor is fixed to the sliding seat through a connecting cylinder, an adjusting head is fixed to the pressure sensor, an adjusting inner hole is formed in the adjusting head, the adjusting inner hole is matched with a valve sheet shaft, a distance sensor is fixed to the side face of the seat plate, and a distance sensing plate is further fixed to the adjusting head. The adjusting device is simple in structure, the valve sheet shaft of the throttle valve can be rapidly adjusted through the adjusting device, the gap between the valve sheet and the inner wall of the inner hole of the throttle valve is guaranteed, and the inner wall of the inner hole of the throttle valve is prevented from being scratched by the valve sheet.

Description

technical field [0001] The invention belongs to the field of throttle valve assembly, and in particular relates to a throttle valve gap adjustment device and an adjustment method. Background technique [0002] The throttle valve is a controllable valve that controls the air to enter the engine. After the gas enters the intake pipe, it will mix with gasoline to become a combustible mixture, which will be burned to form work. It connects the air filter on the top and the engine block on the bottom, which is called the throat of the car engine. [0003] The door of the throttle valve is in the center of the inner hole of the throttle valve when it is assembled, and the throttle valve is fixed in the inner hole of the throttle valve through the door shaft. There is a retaining spring in the spring hole, if the retaining spring is not in the middle of the retaining spring hole, but in the left or right position, this will cause the door shaft to be left or biased under the actio...

Problems solved by technology

[0003] The door of the throttle valve is in the center of the inner hole of the throttle valve when it is assembled, and the throttle valve is fixed in the inner hole of the throttle valve through the door shaft. There is a retaining spring in the spring hole, if the retaining spring is not in the middle of the retaining spring hole, but in the left or right position, this will cause the door shaft to be left or biased under the action of the retaining spring. Right, the door on the door shaft is very likely to be in contact with the inner wall of the inner hole of the throttle valve when it rotates, causing the inner hole of the throttle valve and the edge of the door to be scratched, which may cause gas leakage
