Adaptive near-bore valve block assembly based on hydraulic potential energy recovery and control method thereof
PendingCN122236713AAvoid performing secondary correctionsImprove execution stabilityFluid-pressure actuator safetyServomotor components
This invention discloses an adaptive proximity valve block assembly and its control method based on hydraulic potential energy recovery. The valve block assembly is fixedly connected to a hydraulic cylinder. The valve block internally includes a balance and stabilization passage, a pre-charge buffer passage, a flow-limiting access passage, a main recovery passage, and a buffer chamber. The pre-charge buffer passage has a one-way throttling element and connects to the buffer chamber. The flow-limiting access passage has a fixed throttling orifice connecting the buffer chamber and an energy storage unit. The main recovery passage has a hydraulically controlled directional valve driven by the pressure difference between the buffer chamber and the energy storage unit. After recovery is enabled, the high-pressure return oil preferentially enters the buffer chamber to absorb the first wave of pressure redistribution due to the fast-forward characteristic of the one-way throttling element. Then, it slowly releases the second wave of impact by charging the energy storage unit at a low flow rate through the fixed throttling orifice. After the pressure difference shrinks to a threshold, the hydraulically controlled directional valve automatically opens the main recovery passage. This invention reconstructs the recovery entry from a one-step opening to a hydraulically automatic graded access sequence, significantly suppressing entry pulsation, avoiding main control misjudgment, and improving execution stability.
