一种降低片间漏油风险的泄油方法及片式多路阀
By setting up an oil drain channel between the plates and introducing a pilot stage of the intermediate unloading valve through a one-way valve, the inter-plate oil drain and one-click unloading of the plate-type multi-way valve are realized, which solves the problem of oil leakage due to damage to the inter-plate sealing ring and improves the reliability and applicability of the multi-way valve.

AI Technical Summary
In the existing technology, the sealing ring of the disc multi-way valve is easily damaged when the pressure in the sealing area between the discs increases abnormally, which leads to the risk of oil leakage. In addition, the existing unloading valve has a single function and its application is limited.
An oil drain channel is set between the segments to direct the flow back to the main valve return port, and introduces it to the pilot stage of the intermediate unloading valve through a check valve. Combined with the reversing action of the unloading valve core, one-button unloading is achieved to reduce the pressure between the segments and prevent oil leakage.
It effectively reduces the risk of oil leakage in plate multi-way valves, simplifies the structure of hydraulic systems, improves reliability and practicality, and is suitable for load-sensitive and throttling systems.
