According to the spool structure, the direct-moving overflow valve can be divided into two forms: seat valve and slide valve. Seat valve structure is divided into ball valve and cone valve two kinds; The slide valve structure has the slide valve, the slide valve with the damping hole and the differential slide valve three kinds. The direct-acting overflow valve has a simple structure and high sensitivity, and the pressure is greatly affected by the overflow flow and the pressure regulating deviation is large, so it is not suitable for working under high pressure and large flow, and it is often used as safety valve or occasions where the pressure regulating accuracy is not high [2].
 
When the overflow valve is connected to the system, the hydraulic oil produces a force on the valve core, the direction of the force is opposite to the direction of the spring force. When the pressure of the oil inlet is lower than the setting pressure of the overflow valve, the valve core does not open. At this time, the pressure of the oil inlet mainly depends on the external load. When the oil force is greater than the spring force, the spool opens and the oil flows back to the tank from the overflow port. The spring force increases with the opening of the overflow valve until it is in balance with the hydraulic force. When the overflow valve begins to overflow, the pressure at the oil inlet is basically stable at the set value, thus playing the role of overflow to stabilize the pressure. By adjusting the precompression of spring with pressure regulating screw, the overflow valve pressure value can be adjusted.
