1. The function of hydraulic pressure relief valve

The main function of the hydraulic pressure relief valve is to control the pressure in the hydraulic system and prevent the hydraulic system from being damaged due to excessive pressure. It can reduce the pressure to a range that the system can withstand and return the depressurized fluid to the system. It is usually used in hydraulic systems in the fields of submersibles, construction machinery, aircraft, automobiles and industrial machinery.

2. Application of hydraulic pressure relief valve

Hydraulic pressure reducing valves are widely used in mechanical equipment in various fields. Here are a few application scenarios:

• Engineering machinery field: Hydraulic pressure reducing valves can protect the hydraulic systems of excavators, bulldozers and other mechanical equipment from being damaged by abnormally high pressure.

• Aircraft field: In the aircraft hydraulic system, the hydraulic pressure relief valve can ensure the normal operation of components such as oil cylinders and landing gear, and improve the safety performance of the aircraft.

• Automobile field: Hydraulic pressure reducing valves are also widely used in automobile hydraulic braking and steering systems to ensure accurate braking and steering operations.

3.Principle of hydraulic pressure relief valve

The principle of hydraulic pressure relief valve is to use pressure difference to control the flow of fluid. When the pressure in the system exceeds the set value, the hydraulic pressure relief valve will automatically open to reduce the pressure of the incoming liquid below the set value, and then balance the pressure and return it to the system. When the pressure in the system drops below the preset value, the pressure relief valve will automatically close to maintain the stable state of the system.
