description

Relief valve is a hydraulic pressure control valve, which is mainly used for constant pressure relief, voltage stabilization, system unloading and safety protection in hydraulic equipment. According to different structures, the relief valve of the hydraulic system can be divided into two types: direct-acting and pilot-operated. The combination of the pilot relief valve and the electromagnetic directional valve can form an electromagnetic relief valve, and the combination of the pilot relief valve and the one-way valve can form an unloading relief valve. Functions of the relief valve (1) Relief valve constant pressure relief function: In the quantitative pump throttling adjustment system, the hydraulic oil pump provides a constant flow. Make the excess flow overflow back to the tank to ensure that the pressure at the inlet of the overflow valve is constant, that is, the pressure at the outlet of the pump is constant (the valve port is often opened with pressure fluctuations). (2) Safety protection function: When the system is working normally, the valve is closed. Only when the load exceeds the specified limit (the system pressure exceeds the set pressure), the overflow is turned on, and overload protection is performed to prevent the system pressure from increasing (usually the set pressure of the overflow valve is 10%~20% higher than the maximum working pressure of the system) ). (3) In practical applications, there are generally: as an unloading valve, as a remote pressure regulating valve, as a high and low pressure multi-stage control valve, as a sequence valve, resulting in back pressure (string on the oil return line). The relief valve generally has two structures: 1. Direct-acting relief valve. 2. Pilot-operated relief valve.
