Safety relief valve, also known as relief valve, is a device used for system pressure control, the main role is to protect the system from excessive pressure. When the system pressure exceeds the preset safety value, the safety relief valve will automatically open, and the excess medium (such as gas or liquid) will be discharged into the atmosphere, so as to ensure that the system pressure will not exceed the maximum allowed, to prevent accidents caused by excessive pressure
Working principle
The working principle of the safety relief valve is based on the drive of the medium pressure. When the system pressure exceeds the set safe value, the valve will automatically open, release the excess media, so that the system pressure returned to the safe range. When the system pressure is reduced below the safe value, the valve will automatically close and restore the normal working state of the system
There are many types of safety relief valves
It mainly includes:
spring type safety valve : rely on the force of the spring work, suitable for flammable, explosive or toxic media.
lever type safety valve : rely on the force of the lever weight work, suitable for large opening force occasions.
impulse safety valve : triggered by external signal, suitable for remote control occasions.
Pilot operated safety valve : provides control pressure through a small direct acting valve for applications requiring high sensitivity and precise control
The application of safety relief valve in hydraulic system mainly includes the following aspects :
Safety protection : The main function of the safety relief valve is to protect the hydraulic system from excessive pressure damage. When the system pressure exceeds the set value, the safety relief valve will automatically open, and the excess hydraulic oil will flow back to the tank, thereby reducing the system pressure and preventing equipment failure or damage due to high pressure
In addition, the safety relief valve can also prevent overload and no-load, by adjusting the pressure to limit the size of the load, to ensure that the equipment in the normal working range
maintain system stability : The safety relief valve can maintain the stable operation of the hydraulic system. In the working process of hydraulic equipment, the system pressure may fluctuate due to various factors. The safety relief valve can adjust the pressure in time to ensure the stable operation of the system within the set pressure range
multi-function application : Safety relief valve in the hydraulic system also has a variety of functional applications. For example, it can be used as a unloading valve, the remote control port of the relief valve is connected with the fuel tank through the reversing valve, to realize the unloading function of the oil circuit
In addition, the safety relief valve can also be used as a remote pressure regulator, high and low pressure multistage control valve, sequence valve, etc., to further expand its function and application in the system
Specific application scenario : Safety relief valve is widely used in various hydraulic systems, such as construction machinery, metallurgical equipment, ships and so on. These devices need to withstand large pressure and load in the working process, so the role of safety relief valves is particularly important. By using the safety relief valve, you can effectively improve the safety and reliability of the equipment, reduce the probability of failure
