How does the miniature priority valve energy saving combination valve prevent excessive pressure in the system?

The micro priority valve energy saving combination valve is an advanced hydraulic control device that effectively prevents excessive pressure in the hydraulic system through a series of unique designs and functions, thereby ensuring the safe and stable operation of the system.
Pressure compensated flow control: The built-in pressure compensated flow control function of the miniature priority valve energy saving combination valve is one of its key mechanisms to prevent excessive pressure. This function monitors pressure changes in the system in real time and automatically adjusts based on preset pressure thresholds. When system pressure approaches or exceeds a safety threshold, the pressure-compensated flow control function responds quickly by adjusting the valve's opening to limit the flow of hydraulic oil through the valve. This flow control ensures that the pressure in the system remains within a safe range and prevents pressure increases caused by excessive flow.
Load sensing function: In addition to pressure compensated flow control, the miniature priority valve energy saving combination valve also features load sensing function. This function can monitor the load conditions of various parts of the system in real time and automatically adjust the distribution of hydraulic oil according to load requirements. When the load on a certain part increases, the load sensing function will quickly sense and adjust the flow direction of the hydraulic oil to ensure that the part receives enough hydraulic oil to meet its working needs. At the same time, by optimizing the distribution of hydraulic oil, the load sensing function can also avoid excessive pressure in other parts due to excess hydraulic oil.
The role of the priority valve: In the miniature priority valve energy saving combination valve, the existence of the priority valve is also an important factor in preventing excessive pressure. Priority valves ensure that a specific circuit receives a higher flow of hydraulic oil, giving its function or equipment priority in the system. This design allows critical functions or equipment in the system to receive sufficient hydraulic oil first to meet their normal working needs. At the same time, the priority valve also limits the hydraulic oil flow in other circuits to avoid excessive system pressure caused by excessive flow.
Safety valve setting: To further enhance the safety of the system, mini priority valve energy saving combination valves are usually also equipped with a safety valve or relief valve. When the system pressure exceeds the preset safety value, the safety valve will automatically open and release excess hydraulic oil back to the tank. This mechanism can quickly reduce the pressure in the system and prevent equipment damage or safety accidents caused by excessive pressure.
Intelligent control system: With the continuous advancement of technology, modern miniature priority valve energy saving combination valves may also be equipped with intelligent control systems. The system can monitor the working status of the system in real time and automatically adjust the valve opening and flow based on real-time data. Through intelligent control, the system can more accurately control the flow and pressure of hydraulic oil, further reducing the risk of excessive system pressure.
To sum up, the micro priority valve energy saving combination valve effectively prevents excessive pressure in the hydraulic system through multiple mechanisms such as pressure compensation flow control, load sensing function, priority valve function, safety valve setting, and intelligent control system. big. These mechanisms ensure the safe and stable operation of the system and improve the efficiency and reliability of the system.
