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

A kind of magnetic flow liquid relief valve
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.
Preferably, the periphery of said coil is provided with protecting jacket; Prevent electric leakage.
Compared with prior art, the utility model has the advantages that: the variation of size through the control external impressed current produces different damping forces; And then the control spool is mobile; Reach the purpose of control hydraulic fluid pressure size, it helps electricity-liquid phase and combines, and is easy to operate; Can realize the signal transmission between electrical system and the hydraulic system very easily, help realizing mechanical automation.
Description of drawings
Fig. 1 is the structural representation of a kind of magnetic flow liquid relief valve of the utility model.
Embodiment
Consult the embodiment of Fig. 1 for a kind of magnetic flow liquid relief valve of the utility model; A kind of magnetic flow liquid relief valve; Comprise valve body 1, have inner chamber 2 in the said valve body 1, have the oil inlet hole 3 and spill port 4 that communicate with inner chamber 2 on the said valve body 1; Be provided with spool in the said inner chamber 2; Said spool comprises the cylinder body 5 that is fixed in the inner chamber 2, with the suitable mitre velve 6 of oil inlet hole 3, be arranged on magnetic flow liquid 7 in the cylinder body 5, be arranged on the magnetic flow liquid control gear of cylinder body 5 inner control mitre velves 6 displacement distances, said mitre velve 6 links to each other with the magnetic flow liquid control gear through push rod 8, said magnetic flow liquid control gear comprises I-shaped coil base 9, the elastic position rebounding device 10 that links to each other with push rod 8; Be wound with coil 11 on the said coil base 9; Said elastic position rebounding device 10 is arranged between the coil base 9 and cylinder body 5 sidewalls of mitre velve 6 moving direction, and said elastic position rebounding device 10 is a spring, is equipped with spring seat 12 on the coil base 9 of mitre velve 6 moving direction and cylinder body 5 sidewalls; The two ends of said spring are separately positioned on the spring seat 12 of spring seat 12 and cylinder body 5 sidewalls of coil base 9, and the periphery of said coil 11 is provided with protecting jacket 13.
Oil inlet hole 3 welding system pressure oils, spill port 4 connected tanks.During coil 11 no electric circuits, when the oil liquid pressure in the system was low, mitre velve 6 was withstood in the oil inlet hole 3 by spring action, and with oil inlet hole 3 sealings, valve is in closed condition; When the pressure in the oil inlet hole 3 during greater than the elastic force of spring, oil pressure backs down mitre velve 6, and oil flows back to the fuel tank from spill port 4, and this moment, the pressure of oil inlet hole 3 also just can not continue to raise.When coil 11 is switched on door, through the size of control external impressed current, make to produce different damping forces in the spool, and then control moving of spool, the break-make of control oil inlet hole 3 just can be adjusted oil pressure relief.
The above is merely the specific embodiment of the utility model; But the technical characteristics of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
