Technical Field
The invention relates to the field of valve assemblies, in particular to a high-precision ultra-large flow valve assembly.
Background
The high-pressure pump valve is an important component of the high-pressure pump, and the liquid inlet valve and the liquid outlet valve adopted by the high-pressure pump valve are all passive valves without power. When the plunger extends out of the working stroke, the thrust of the plunger enables the liquid to generate pressure, the liquid discharge valve is opened, and meanwhile, the liquid inlet valve is closed under the action of the spring force; the plunger continues to move forwards and is accelerated and decelerated according to the curve , the drain valve is opened more due to the increase of the flow velocity under the impact of flowing liquid, the flow velocity is reduced to open the gradually-decreasing valve and open, and meanwhile, the drain valve is closed under the action of the spring force; the plunger piston continues to retract, the liquid inlet valve retracts after the liquid flow plunger piston extends to the farthest, the liquid inlet stroke starts, and the liquid pressure in the liquid inlet channel enables the liquid inlet to be opened under the impact of the liquid inlet and gradually reduced.
