Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic systems, in particular to a modular speed-increasing hydraulic component. Background Art

[0002] Existing hydraulic systems typically select appropriate motors, pumps, valves, and other components based on customer requirements, including actuator size, speed, and pressure. Once the hydraulic system is built, the actuator speed is fixed. For example, solenoid directional valves are available in 6-, 10-, and 16-port sizes.

[0003] To meet the acceleration requirements, the only way to increase the oil pump displacement and motor power is to increase the diameter of the solenoid reversing valve to meet the speed requirements. This method requires changing relatively large components of the hydraulic system, is difficult to operate, and requires a lot of trouble to modify, which increases the cost of the modification.

[0004] Therefore, we propose a modular speed-increasing hydraulic assembly to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a modular speed-increasing hydraulic assembly to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a modular speed-increasing hydraulic assembly, comprising: a valve block, a first cartridge overflow valve fixedly installed on the upper end of the valve block, an accumulator installed on the first cartridge overflow valve, the oil circuit of the first cartridge overflow valve and the valve block are connected, and the accumulator is connected to the oil circuit of the first cartridge overflow valve.

[0007] Preferably, a first pressure regulating valve and a pressure gauge are installed on the side of the first plug-in relief valve.

[0008] Preferably, an electromagnetic reversing valve and a one-way valve are installed on the side of the valve block.

[0009] Preferably, a pressure sensor is installed on the side of the valve block.

[0010] Preferably, a second cartridge relief valve is fixedly stacked on the lower end of the valve block, and a first reversing valve is mounted on the second cartridge relief valve.

[0011] Preferably, at least one third valve block is fixedly superimposed on the lower end of the second plug-in overflow valve, and the third valve block is provided with a one-way PT port, which is connected to a one-way throttle valve. The one-way throttle valve is fixedly installed on the third valve block, and a second reversing valve is installed on the one-way throttle valve.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By composing modular components such as accumulator, safety relief valve, pressure gauge, pressure sensor, electromagnetic reversing valve and oil circuit block, the speed can be increased by installing the components into the original hydraulic system. Through modularization, the speed of hydraulic actuators can be increased without changing the original hydraulic system, oil pump, motor and other components. BRIEF DESCRIPTION OF THE DRAWINGS
