Problems solved by technology

[0002] When the hydraulic cylinder pushes the load to move, if the load is heavy and the speed is fast, due to the inertia, the load will drive the piston of the hydraulic cylinder to continue to move forward, which will cause a sudden pressure in the hydraulic cylinder cavity. It will increase the pressure peak, and the instantaneous pressure shock will not only cause vibration and noise, but also damage the sealing device, pipeline and hydraulic components; it will also increase the effective area of ​​the other chamber of the hydraulic cylinder, but because the oil supply is stopped , so the cavity forms a negative pressure, causing cavitation

Abstract

The invention discloses a hydraulic valve with two-way brake buffering and oil replenishment functions. The invention includes a valve block and two one-way overflow valves with the same component parts installed on the valve block and symmetrical structural layout; the invention has a simple structure , easy to process, mainly used for overload overflow protection and reverse oil supply protection caused by inertia when the hydraulic cylinder is braking in the forward and reverse directions.

Description

technical field [0001] The invention relates to the technical field of hydraulic system pressure control components, in particular to a hydraulic valve with two-way brake buffering and oil replenishment functions, which is mainly used for overload overflow protection and Reverse charge protection. Background technique [0002] When the hydraulic cylinder pushes the load to move, if the load is heavy and the speed is fast, due to the inertia, the load will drive the piston of the hydraulic cylinder to continue to move forward, which will cause a sudden pressure in the hydraulic cylinder cavity. It will increase the pressure peak, and the instantaneous pressure shock will not only cause vibration and noise, but also damage the sealing device, pipeline and hydraulic components; it will also increase the effective area of ​​the other chamber of the hydraulic cylinder, but because the oil supply is stopped , so the cavity forms a negative pressure, causing cavitation.
