The importance of AR pressure regulating valve for high-pressure environmental cleaning machine

The importance of pressure regulating valves for high-pressure environmental cleaning machines lies in the fact that they can operate at any working pressure under the rated working pressure.

The pressure regulating valve is an important scheduling organization to ensure and end this work.

Due to the fact that most high-pressure cleaning machines are equipped with high-pressure water generation devices that belong to constant flow volume pumps, overflow will occur at any pressure below the rated working pressure.

ButARA pressure regulating overflow valve is a device that can simultaneously end the pressure regulation and overflow of high-pressure water generating equipment, which is called a pressure regulating overflow valve.

The main functions are as follows:

1Constant pressure overflow function: In the quantitative pump energy-saving scheduling system, the quantitative pump supplies a stable flow rate. When the system pressure increases, it will require a decrease in flow rate.At this point, the overflow valve opens, allowing the remaining flow to overflow back into the oil tank, ensuring that the inlet pressure of the overflow valve, that is, the outlet pressure of the pump, is stable(The valve port often opens with unstable pressure).

2Voltage stabilizing effect: The relief valve is connected in series on the return oil path, causing back pressure on the relief valve and increasing the stability of the moving parts.

3System unloading function: Connect a low flow solenoid valve in series with the remote control port of the overflow valve. When the solenoid is energized, the remote control port of the overflow valve is connected to the oil tank, and the hydraulic pump is unloaded.The overflow valve is now used as an unloading valve.

4Safety protection function: When the system is working normally, the valve is closed.Just open the overflow when the load exceeds the rules, perform overload protection, and prevent the system pressure from increasing again.
