Description

technical field

[0001] The present application relates to the technical field of valves, in particular to a fuel flow valve. Background technique

[0002] The fuel regulator is a mechanism that adjusts the fuel supply of the engine to reasonably match the working state of the engine. When the working state of the engine is changed, the fuel is supplied reliably to ensure stable combustion, no flameout, no surge of the intake port and compressor, no over-revving of the engine, no over-revving and stable operation. In a fuel regulator system, a flow valve is usually required to control the flow. The flow valve is composed of a valve body and a valve core. The valve body controls the flow by means of the movement of the valve core. The structure is complex, and the constant flow valve can only control the liquid flow in the pipeline system at a fixed value, and cannot perform dynamic adjustment. Therefore, it is necessary to provide a fuel flow valve which has a simple struct...
