Background Technology
[0002] The multi-functional hydraulic control valve group of the hydraulic take-up and rewind machine consists of a power unit, control valves, pipelines, and hydraulic components. The power unit provides the system with the necessary power, and the control valves control the direction and speed of the hydraulic oil. The oil is then delivered to each hydraulic component through pipelines to activate it.
[0003] The existing multi-functional hydraulic control valve group of hydraulic take-up and release machine has a large number of control valves and pipelines, resulting in a messy overall layout and increasing the number of spare parts to be purchased and the difficulty of management.
[0004] To address the problem that existing multi-functional hydraulic control valve assemblies for hydraulic take-up and play machines have a large number of control valves and pipelines, resulting in a messy overall layout and increased purchase quantity and management difficulty of spare parts, this multi-functional hydraulic control valve assembly for hydraulic take-up and play machines integrates the redundant control valves and pipelines into one valve assembly. At the same time, the valve block adopts an L-shaped structure, which can reduce space and make the operating handle at the same height after the operating valve is installed for convenient operation. Utility Model Content

[0006] The technical solution of this utility model is as follows: a multi-functional hydraulic control valve group for a hydraulic take-up and release machine with adjustable pressure reduction, comprising a main valve block, a first directional valve, a balance valve, an extension valve block, a speed control valve, a main directional valve, an adjustment component, a sealing component, and a locking component. The first directional valve is provided on one side of the main valve block, the balance valve is provided below the first directional valve, the extension valve block is provided below the balance valve, the speed control valve is provided at one end of the main valve block, the main directional valve is provided on the other side of the main valve block, the adjustment component is provided at the bottom of one side of the main valve block, the sealing component is provided on one side of the adjustment component, and the locking component is provided on one side of the sealing component.
[0007] Preferably, the main valve block integrates multiple control valves and pipelines to effectively control the flow direction and speed of the power oil. The first directional valve changes the flow direction of the power oil, thereby controlling the direction of movement of the hydraulic components. A balance valve balances pressure to prevent overload and maintain system stability, preventing instability or damage due to sudden pressure changes. An expansion valve block allows for the addition of extra control functions or the connection of other hydraulic components to the multi-functional hydraulic control valve group. The number of hydraulic components can be increased or decreased as needed. High-pressure oil can be introduced through openings in the expansion valve block to provide power to other hydraulic components. A speed control valve controls the movement speed of the hydraulic components. Adjusting the opening of the speed control valve changes the flow rate through the valve, thus achieving precise control of the hydraulic component's movement speed. The main directional valve controls the direction of movement of the main hydraulic components. An adjustment assembly adjusts the multi-functional hydraulic control valve group for the hydraulic rewinder. A sealing assembly seals the adjustment assembly, and a locking assembly locks and secures the adjustment assembly. This multi-functional hydraulic control valve group for the hydraulic rewinder can control multiple hydraulic components by adding or removing hydraulic control valves as needed.
[0008] Preferably, the regulating component includes a regulating system pressure valve core and a regulating system pressure valve spring, with the regulating system pressure valve core provided on one side of the main valve block and the regulating system pressure valve spring provided at one end of the regulating system pressure valve core.
[0009] Preferably, the sealing assembly includes a sealing gland and an O-ring, with the sealing gland located on one side of the regulating system pressure valve spring and the O-ring located on one side of the sealing gland.
[0010] Preferably, the locking assembly includes a regulating system pressure valve stem and a locking nut, with the regulating system pressure valve stem located on one side of the O-ring and the locking nut located on the other side of the regulating system pressure valve stem.
[0011] The beneficial effects of this utility model are:
[0012] The unloading valve is installed inside the valve block. During operation, the unloading valve is closed. When operation is paused, the throttle valve closes, and the system automatically unloads, which can effectively reduce the system's no-load pressure and motor load, as well as reduce the heat generated by the system. In addition, a hole is opened on the side of the high-pressure oil inlet of the multi-functional hydraulic control valve group valve block to introduce high-pressure oil, which can be extended to provide power to other hydraulic components valve blocks on the equipment. The unloading valve core can adjust the pressure of the introduced high-pressure oil according to the working pressure of the hydraulic components. This multi-functional hydraulic control valve group of the hydraulic take-up and release machine can add or remove hydraulic control valves to control multiple hydraulic components as needed.
