The working principle and function of the R215VS walking foot valve
assembly are as follows:
Working principle
When the walking control lever is in the middle position, the oil
inlet oil circuit is cut off, and the four working ports are
connected to the oil return port through the internal channel to
realize oil return. Move the walking control lever backward, and
the rocker arm and other components convert the backward movement
of the control lever into the downward movement of the right push
rod, and transmit the downward displacement of the push rod to the
valve core through the spring seat clamp spring and the balance
spring. Under the joint action of the balance spring and the outlet
secondary pressure, the valve core maintains balance with the force
acting on the push rod and maintains a constant position. At this
time, the outlet pressure remains constant. When the foot valve is
in the maximum working position, the pressure relief effect of the
valve core fails, and the outlet pressure increases to the same as
the inlet. When the travel control lever is released, the right
push rod has a tendency to reset quickly under the combined action
of the reset spring and the thrust difference between the upper and
lower damping chambers. However, due to the damping effect of the
throttle hole in the left push rod, the downward movement speed of
the left push rod is limited. The travel control lever and the
right valve core can be reset smoothly, reducing the impact of
high-pressure oil on the travel system. During the upward movement
of the right push rod, the oil in the upper damping chamber is
discharged through the one-way valve in the push rod.
Function
It is mainly used to control the travel of the excavator. By
stepping on the foot valve, the flow and pressure of the hydraulic
oil are controlled, and then the speed and torque of the travel
motor are adjusted to realize the control of the excavator's
forward, backward, steering and travel speed. At the same time, it
can ensure the stability and accuracy of the walking action, so
that the operator can accurately control the travel of the
excavator according to work needs.
