Network optimization information:

The pump pressure first promotes the movement of the hydraulic cylinder 1 of the starting solenoid valve, and acts on the area A through the oil inlet of the sequence valve. When the movement of area A is completely completed, the pressure rises. When the propulsion force of area A is greater than the adjustment value of the spring, the relief valve body rises to make the oil inlet and the oil outlet connected, and the hydraulic cylinder 2 moves. Speed regulating valve by adjusting the valve body and the area of the throttle between the valve body and the local resistance to regulate the flow, so as to control the movement speed of the actuator. According to the use, regulating valve can be divided into five types.

Starting solenoid valve throttle valve: after adjusting the throttle port area, the load pressure changes little, and the motion of the actuator with low uniformity requirements is basically stable.

Speed regulating valve: when the load pressure changes, throttle valve inlet and outlet pressure difference can be maintained at a certain value. In this way, after adjusting the throttle port area, no matter how the load pressure changes, the speed regulating valve can keep the flow through the throttle valve constant, so that the running speed of the executive parts is stable. Shunt valve: two actuators of the same oil source regardless of the load size can obtain the same flow is the same flow shunt valve or synchronous valve, according to the proportion of the distribution of flow is proportional shunt valve.
