Description

 

Due to its structural characteristics, the relief valve is not suitable for use in large-flow hydraulic systems. On the one hand, the large flow environment directly makes the adjustment handle of the relief valve difficult to rotate, or even impossible to adjust, which affects the work. On the other hand, the structure of the direct-acting relief valve causes its opening and closing characteristics to be relatively poor. Therefore, the direct-acting relief valve is used in hydraulic systems with small flow and low requirements. For hydraulic systems with large flow and high precision requirements, pilot-operated relief valves are generally used.

Relief valve, its structure is divided into two parts, the pilot part is a small size direct-acting relief valve, which is connected with the main valve, the two constitute the relief valve. Such structural features make the adjustment torque of the relief valve much smaller than that of the direct-acting relief valve, and the opening and closing characteristics are good.

The working principle of the relief valve: when the pressure oil flows in from the inlet, the pressure acts on the lower end plane of the main spool. A damping hole is designed in the valve body, and the pressure oil enters the right chamber of the pilot valve after passing through, and finally acts on the spool of the relief valve. The valve core of the relief valve is normally closed by the thrust of the spring, and the preset pressure of the spring can be adjusted through the external adjustment handle. When the hydraulic pressure is less than the pre-set pressure of the spring, the pilot spool is always in a closed state, and the main spool has no corresponding action at this time. When the system pressure rises, the internal hydraulic pressure of the pilot valve is greater than the pre-set pressure of the spring, and the pilot valve opens. Under the depressurization effect of the orifice, a pressure difference is generated between the main spool and the bottom. Therefore, the main spool rises, and the originally sealed The oil inlet and the oil outlet are connected, and the pressure oil directly flows from the oil inlet to the oil outlet to realize unloading.

 


Characteristic

 

1. Small size, can be installed in narrow space.
2. Since it is a cartridge type, it is easy to install and remove, and it has excellent maintainability.
3.The cartridge holes of the proportional valve and the switching valve are shared, and it is convenient to replace the circuit.
4. It corresponds to the solenoid valve block of various circuits, making multiple solenoid valves into a whole.
5. Fast delivery with good price
