Abstract
The utility model discloses a magnetorheological fluid overflow valve which comprises a valve body, wherein an inner cavity is arranged inside the valve body, an oil inlet hole and an oil return hole which are communicated with the inner cavity are arranged on the valve body, and a valve core is arranged in the inner cavity. The valve core comprises a cylinder body fixed in the inner cavity, a cone valve matched with the oil inlet hole, magnetorheological fluids arranged in the cylinder body, and a magnetorheological fluid control device arranged in the cylinder body and used for controlling the moving length of the cone valve. The cone valve is connected with the magnetorheological fluid control device through a push rod. The magnetorheological fluid overflow valve has the advantages that by means of control for size changes of external currents, different damping forces are generated, then moving of the valve core is controlled, the purpose of controlling intensity of pressure of hydraulic oil is achieved, combination of electricity and liquid is benefited, operation is convenient, signal transmission between an electric system and a hydraulic system can be achieved conveniently, and achievement of mechanical automation is benefited.
Description
Technical field
The utility model relates to a kind of magnetic flow liquid relief valve.
Background technique
Common direct-acting overflow valve if regulate its inlet pressure, need turn adjusting handle, changes the pre compressed magnitude of spring, just can adjust the oil pressure relief of relief valve.Common direct-acting overflow valve is unfavorable for that electricity-liquid phase combines, and inconvenient operation is moved loaded down with trivial detailsly, is unfavorable for today of the development of mechanical automation.Common direct-acting overflow valve generally only is used for small flow or low pressure occasion.
The model utility content
The purpose of the utility model is to provide a kind of magnetic flow liquid relief valve, and can effectively solve existing direct-acting overflow valve oil pressure relief is fixed value, is unfavorable for the problem of controlling.
In order to solve the problems of the technologies described above; The utility model is realized through following technological scheme: a kind of magnetic flow liquid relief valve; Comprise valve body; Have inner chamber in the said valve body, have the oil inlet hole and the spill port that communicate with inner chamber on the said valve body, be provided with spool in the said inner chamber; Said spool comprises the cylinder body that is fixed in the inner chamber, with the suitable mitre velve of oil inlet hole, be arranged on magnetic flow liquid in the cylinder body, be arranged on the magnetic flow liquid control gear of cylinder body inner control mitre velve displacement distance, said mitre velve links to each other with the magnetic flow liquid control gear through push rod.
Preferably, said magnetic flow liquid control gear comprises I-shaped coil base, the elastic position rebounding device that links to each other with push rod, is wound with coil on the said coil base, and said elastic position rebounding device is arranged between the coil base and cylinder side wall of mitre velve moving direction; Simple in structure, make easy to process.
Preferably, said elastic position rebounding device is a spring, is equipped with spring seat on the coil base of mitre velve moving direction and the cylinder side wall, and the two ends of said spring are separately positioned on the spring seat of spring seat and cylinder side wall of coil base; Easy for installation, reliable performance.
