After a hydraulic valve fails or fails, most enterprises adopt the method of replacing new components to restore the function of the hydraulic system, and the failed hydraulic valve becomes a waste product. In fact, most parts of these hydraulic valves are still in good condition and can be restored to function after partial maintenance. The significance of studying the maintenance of hydraulic valves is not only to save the cost of purchasing components. When a failed hydraulic valve has no spare parts or requires a long time to order, and the hydraulic valve equipment may be shut down for a long time, maintenance can temporarily maintain the operation of the equipment and even the entire production line, with considerable economic benefits. In the practice of hydraulic valve maintenance, commonly used maintenance processes include hydraulic valve cleaning, parts combination selection, repair dimensions, and so on.

Hydraulic circuit: A component of a hydraulic device that consists of various hydraulic components and has a certain function.
Spool type valve core (cylindrical valve core): A part that cooperates with a cylindrical sliding surface to open and close the flow path when it moves along the axial direction.
Circuit diagram: Hydraulic circuit diagram represented by hydraulic graphical symbols.
Oil drain: The return of oil or this phenomenon of oil from a channel (or pipe) in a hydraulic component to a tank or collector.
Hydraulic station: a hydraulic source device composed of a hydraulic pump, a driving motor, a fuel tank, an overflow valve, etc., or a hydraulic device including a control valve.
Oil leakage: A small amount of oil flowing from a part that should be sealed under normal conditions.
Rated pressure: High pressure for continuous use.
Static seal: used for stationary parts to prevent liquid leakage.
Back pressure: The pressure applied in the opposite direction of the return side or pressure acting surface of the hydraulic circuit.
Dynamic seal: Used for sealing the relative sliding part.
Fluid clamping phenomenon: In the interior of a spool valve, due to uneven flow, the pressure distribution on the central shaft is uneven, forcing the valve core towards the valve body (or valve sleeve), making it unable to move.
