Proportional pressure reducing valve is a valve that can accurately control the fluid pressure. The "proportional" in its name refers to the proportional relationship between the output pressure of the valve and the input signal. This paper will introduce the principle, application and optimization method of proportional pressure reducing valve in detail.
proportional pressure reducing valveIt is a valve that can accurately control the fluid pressure. The "ratio" in its name refers to the proportional relationship between the output pressure of the valve and the input signal. This paper will introduce the principle, application and optimization method of proportional pressure reducing valve in detail.
Principle of 1. proportional pressure reducing valve
proportional pressure reducing valveThe core components are the spool and the valve body, by adjusting the position of the spool to change the flow area of the valve, so as to achieve the control of fluid pressure. The valve core is generally made of magnetic material and driven by external electromagnetic force.
In the proportional pressure reducing valve, the input signal generates a magnetic field through the electromagnetic coil, and the magnetic lines of force pass through the magnetic sleeve and the spool to move the spool. When the input signal is strengthened, the spool moves to the right to reduce the flow area of the valve port and increase the fluid resistance, thereby reducing the output pressure; on the contrary, when the input signal decreases, the spool moves to the left to strengthen the flow area of the valve port and reduce Fluid resistance, thereby increasing the output pressure.
