hydraulic pressure relief valve

hydraulic pressure relief valve

It controls the flow of liquids and is widely used in aviation, chemical industry, shipbuilding, machining and other fields.Its main function is to achieve precise control of liquid flow, direction, pressure and other parameters.The hydraulic control valve can control and adjust the flow rate, pressure and other parameters of the hydraulic system according to different functional requirements, and can cut off the fluid and change the flow direction.

The principle is mainly to change the channel of liquid flow through the movement of the valve core, so as to control the flow rate, pressure and flow direction of the liquid.The position of the valve core determines the flow direction of the fluid and the size of the liquid flow through the valve core channel.Under different working pressures, the hydraulic control valve can adjust the position of the spool to achieve accurate control of liquid flow and pressure.

Material: Carbon steel, which ensures the durability and stability of the valve block

Connection form: threaded connection to adapt to different installation needs

Drive mode: electronic drive, providing precise control options

Scope of application: Widely used in hydraulic machinery and equipment, especially in situations where precise control of fluid pressure and flow is required

Provide quality and performance assurance

Nominal pressure: usually between -30~110℃, which ensures its applicability in various environments

It is based on the principle of balance between the hydraulic pressure and the spring force at the bottom of the valve core.When the system pressure exceeds the pressure set by the relief valve, the valve core is moved upward by the pressure, opening the overflow port, so that the excess fluid returns to the fuel tank, thereby maintaining the stability of the system pressure.The relief valve sets the opening pressure by adjusting the preload of the spring, and the pressure regulating range of the relief valve can be adjusted by replacing the springs of different stiffness.In addition, the relief valve also has a safety protection effect. When the system load exceeds the specified limit, the relief valve is opened for overload protection to prevent the system pressure from continuing to increase.‌

According to the different structure and working principle of the relief valve, it can be divided into direct-acting relief valve and pilot-operated relief valve.The direct-acting relief valve has a simple structure and high sensitivity, but it is not suitable for high-pressure and large-flow applications.The pilot relief valve consists of two parts: the pilot valve and the main valve, which are suitable for medium and high pressure and large flow occasions.The working principle of the pilot relief valve is that when the system pressure rises to a certain extent, the pilot valve opens, causing the pressure difference between the upper and lower chambers of the main valve to produce, pushing the main valve core to move, and realizing oil overflow.‌

The electromagnetic relief valve is to add an electromagnetic directional control valve on the basis of the pilot relief valve, and realize the unloading and loading of the hydraulic system by controlling whether the electromagnetic directional control valve is energized or not.The unloading relief valve allows the pump to supply oil to the system when the system pressure is not high, and opens the overflow when the pressure rises to realize the automatic loading and unloading of the system. It is often used in conjunction with the accumulator.
