Abstract
The utility model relates to a hydraulic cartridge valve system, which is divided into an oil source valve plate and a control valve plate and comprises a pump P 1 with low pressure and big flow capacity and a pump P 2 with high pressure and small flow capacity, and a cartridge valve is installed on thereof to adjust the flow capacity, wherein the P 1 and P 2 are gathered to system pressure P through an inner channel, and the direction of the master cylinder is controlled by the cartridge valve, an A and a B ports are respectively interfaces of the upper cavity and the lower cavity of the master cylinder, and a P and a T are oil resource ports which output oil to other valve plate. Cartridge components of the cartridge valve plate of the utility model are assembled in a valve block, oil leakage of the valve is small, oil leakage is avoided, a control valve plate is connected with the A and the B ports of the master cylinder, after being improved, the shape is good and tidy, the adjustment and maintenance are convenient and the quality of products is improved, and the hydraulic cartridge valve system has the advantages of small volume, less pipelines, less leakage and simple structure and is suitable for working sites with high pressure and large flow.
Description
Technical field
The utility model relates to the closing device field, relates in particular to a kind of hydraulic cartridge valve system.
Background technique
This equipment of the producer of domestic many production closing devicees and Japan's product all adopts the hydraulic system of common board-like guiding valve at present.That this board-like slide plate takes up an area of, takes up space is bigger, pipeline is many, oil leakage phenomenon often occurs, directly influences the appearance quality of product.
Summary of the invention
The utility model is that a cover cartridge valve system will be provided, and improves the defective that oil leakage phenomenon often appears in existing equipment.
A kind of hydraulic cartridge valve system, be divided into oil sources valve plate and control valve plate, comprise low pressure and mass flow pump P1 and high-pressure low-flow pump P2, cartridge valve is housed on it regulates flow, P1, P2 are pooled to system pressure P by the inner passage, by cartridge valve control master cylinder direction, A, B mouth are the interface of the upper and lower cavity of master cylinder again, and P, T are the oil sources mouth that outputs to other valve plates.
The system that described hydraulic cartridge valve is formed is installed on the crossbeam of main frame, and valve plate provides oil sources by two pumps, reaches different actions by cartridge valve group control master cylinder.
Described cartridge valve piece is combined into system, and the inlet by pump and outlet A, B carry out the control of exercises to master cylinder.
Beneficial effect
The oil sources valve plate connects two pumping sources, can carry out stepless speed regulation at this place, and also can step-less adjustment under certain pressure.Pick-and-place components is assembled in valve piece inside in the plug-in mounting valve plate, and the leakage of oil of valve is very little, has avoided oil leakage phenomenon, and the control valve plate connects A, the B mouth of master cylinder, and it is attractive in appearance neat to improve the back layman, adjusts easy to maintenancely, improves the quality of products.Have that volume is little, pipeline is few, leakage is little, simple in structure, be applicable to the workplace of the big flow of high pressure.
Description of drawings
Fig. 1 is a hydraulic schematic diagram of the present utility model;
Fig. 2 is the assembling schematic representation of cartridge valve.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
A kind of hydraulic cartridge valve system, as shown in Figure 1, P1 is the low pressure and mass flow pump in the hydraulic schematic diagram, and pressure is regulated by cartridge valve 1, and one-way valve is a control low pressure oil sources.P2 is the high-pressure low-flow pump, adjusts pressure and flow by Proportional valve.P1, P2 are pooled to system pressure P by the inner passage, again by cartridge valve 1 control master cylinder direction.A, B mouth are the interface of the upper and lower cavity of master cylinder.The pressure of system carries out flow, pressure step-less adjustment by Proportional valve in specific scope.Fig. 2 assembles in the schematic representation, and P1, P2 are the inlet opening of low pressure pump and high-pressure service pump, and P, T are the oil sources mouth that outputs to other valve plates.But two valve plate modular combination among the figure, A, B on the control valve plate are the interface of the upper and lower cavity of master cylinder, T is total drainback passage.
