Product Description/Features:
First, the basic structure and working principle of pilot proportional valve
The pilot proportional valve comprises a spool, a spool guide sleeve, a proportional electromagnet, a permanent magnet, a flow regulating potentiometer, a pressure regulating potentiometer, etc. When it is in the liquid control center state, the pilot proportional valve is closed, and the pressure in the control oil circuit does not change, and the oil cannot pass through, so as to maintain the stability of the oil circuit.
When the electromagnet is energized, according to the action of the proportional electromagnet and the permanent magnet, the valve core is shifted to achieve the purpose of adjusting the pressure and flow of the liquid path. That is, by adjusting the flow and pressure in the control liquid path, the precise control and adjustment of the hydraulic system can be achieved.
Second, the role of pilot proportional valve in the hydraulic system
The pilot proportional valve plays an important role in the hydraulic system. Common applications are as follows:
1. Control the speed and stroke of the hydraulic cylinder: the pilot proportional valve can adjust the flow rate and pressure of the liquid, which is used to control the speed and stroke of the hydraulic cylinder to achieve a more accurate control effect.
2. Adjust the pressure of the hydraulic system: the pilot proportional valve can achieve accurate control and adjustment of the hydraulic system by adjusting the pressure in the hydraulic system.
3. Change the flow rate of the hydraulic system: the pilot proportional valve can adjust the flow rate in the control liquid path to meet the needs of different working conditions and improve the efficiency of the system.
4. Maintain the stability of the system: the pilot proportional valve can maintain the stability of the hydraulic system, prevent fluctuations and pressure instability in the system, and improve the safety and reliability of the system.
Third, the advantages and disadvantages of pilot proportional valve
1. Advantages: The pilot proportional valve can realize the accurate adjustment and control of the hydraulic system, with fast response speed, high control accuracy, wide adjustment range, good reliability and other advantages.
2. Disadvantages: The main disadvantage of the pilot proportional valve is that the installation and maintenance is relatively complex, and requires professional operation and maintenance.
To sum up, the pilot proportional valve is a commonly used component in the hydraulic system, and its role is mainly to achieve accurate control and regulation of the hydraulic system by adjusting the flow and pressure in the control liquid path. At the same time, the pilot proportional valve also has the advantages of fast response speed, high control accuracy, wide adjustment range, good reliability, etc., but its installation and maintenance is relatively complex, requiring professional personnel to operate and maintain.
