Damping structure of the pressure compensation control valve applied to the hydraulic system of a forklift

摘要

In the hydraulic system of the forklift, when the mast is lowered, no matter what the load of the carrier is, a certain lowering speed must be maintained, which is the pressure compensation adjustment of the ballast dam structure suitable for the hydraulic system of the forklift.The specific method of this study is.With the adjustment of euro area, the pressure compensation regulating valve always flows a certain flow in one direction,The pressure regulating and compensating valve connected with the lift cylinder of the forklift is supported by the elastic spring inside the shell. According to the control flow, the oil quantity inside the shell inserted into the plug can be adjusted freely,At the back end of the above sample, supported by the plunger resistance spring, under the pressure of the control process, the dam elevator adopts the cavity behind the plunger to transfer the pressure,The plunger is supported by the resistance spring and contacted with the accessories to make the reservoir quickly form a feature according to the pressure variation of the control flow.
