Description

Technical field [0001] The invention relates to an integrated multifunctional hydraulic component which has the functions of isolation on-off, overflow pressure limiting, and backflow pressure relief. Background technique [0002] In the hydraulic control system, in order to achieve the purpose of rapid pressure increase, overflow pressure limiting, and return pressure relief, the hydraulic system needs to use two-position two-position solenoid valves, pressure-limiting relief valves, and two-position two-position normally-off solenoid valves. In order to form a complete hydraulic control system, the hydraulic control block that needs to be adjusted is controlled. Before the solenoid valve operates, the hydraulic oil reaches the hydraulic control block from the liquid inlet through the two-position solenoid valve, which can quickly pressurize the control block. , After the hydraulic pressure in the adjustment block reaches the target hydraulic pressure, the hydraulic oil flow...

AI Technical Summary

Problems solved by technology

[0002] In the hydraulic control system, in order to achieve the purpose of fast boosting, overflow pressure limiting, and backflow pressure relief, two-position two-position normally open solenoid valves, pressure-limiting overflow valves, two-position two-position normally-off solenoid valves are required in the hydraulic system. In order to form a complete hydraulic adjustment system, hydraulically control the hydraulic adjustment block that needs to be adjusted. Before the solenoid valve acts, the hydraulic oil reaches the hydraulic adjustment block from the liquid inlet through the two-position two-position normally open solenoid valve, which can quickly pressurize the adjustment block. , after the hydraulic pressure in the regulating block reaches the target hydraulic pressure, the hydraulic oil flows out through the relief valve, so as to ensure that the hydraulic pressure in the regulating block remains stable. The action of the open solenoid valve changes from normally open to disconnected, and the action of the two-position two-normally-off solenoid valve changes from normally-off to connected. For the purpose of pressure relief, in order to control the hydraulic pressure in the hydraulic adjustment block, the hydraulic control system composed of discrete hydraulic components is large in size, high in cost, and complex in system. Multi-function hydraulic components become necessary
