Baffle valve structure

Abstract

The invention provides a baffle valve structure. The baffle valve structure comprises a valve body, a valve plate and a shaft; the left end and the right end of the valve body are provided with an inlet flange and an outlet flange respectively; the bottom face of the interior of the valve body is of a plane structure, the shaft is installed at the junction of the inner side face and the bottom face of the inlet flange, and the corresponding portion of the valve body is provided with a shaft hole used for installing the shaft; the bottom end of the valve plate is fixedly installed on the shaftand can rotate along with the shaft; and the inner side face of the left end of the valve body is provided with a first annular sealing strip used for cooperating with the valve plate when the valve plate is closed, and the valve plate is provided with a second sealing strip cooperating with the first sealing strip. According to the baffle valve structure, reliable sealing can be achieved when thevalve is closed, the valve plate is horizontally arranged and completely attached to the bottom face, then the valve plate completely does not influence a flowing channel of the valve, and thereforethe valve is suitable for a compressor air inlet control valve mode of a sequential supercharged engine and has the obvious effect of reducing the air inlet resistance of the engine.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and in particular relates to a baffle valve structure. Background technique [0002] For engines with a sequential supercharging system, the compressor control valve is generally arranged at the inlet of the compressor, which is conducive to lower operating temperature and is convenient to cut off the air. [0003] However, when the compressor control valve of this structure is opened, the valve plate will cause air intake throttling, which will affect the efficiency of the sequential supercharging system; [0004] In addition, the existing structure is often designed with a multi-layer packing structure at the valve shaft. Due to the friction between the valve shaft and the packing, the driving torque of the valve is large, which does not meet the low driving torque requirement of the sequential pressurization system for high-temperature valves.

[0004] In addition, the existing structure is often designed with a multi-layer packing structure at the valve shaft. Due to the friction between the valve shaft and the packing, the driving torque of the valve is large, which does not meet the low driving torque requirements of the sequential boosting system for high-temperature valves.
