Embodiment
As shown in figure 1, a kind of embodiment of magnetorheological pilot-operated overflow valve of the utility model uses following technology
Scheme：A kind of magnetorheological pilot-operated overflow valve is mainly made up of pilot valve and main valve, and pilot valve is installed on main valve upper end, wherein first
Pilot valve is by pilot valve lower valve body 1, pilot valve upper valve body 2, magnetic conductive disk 3, pilot valve core support base 4, sealing ring 5, electromagnetic wire
Circle 6, pilot valve core 7, magnetic conduction cylinder 8, plug 9, damping block 10 are constituted；Magnet coil 6 is wrapped on pilot valve core 7, electricity
The outer ring of magnetic coil 6 has sealing ring 5 to encase, and the two ends of pilot valve core 7 are fixed by pilot valve core support base 4, pilot valve core branch
Support seat 4 is embedded on the inwall of magnetic conduction cylinder 8, and magnetic conduction cylinder 8 is arranged in pilot valve upper valve body 2 and pilot valve lower valve body 1, damping
Block 10 and plug 9 are also respectively installed in pilot valve upper valve body 2, and main valve is by spring 11, valve core of main valve 12, damping hole 13, master
Valve body 14 is constituted；Spring 11 is arranged in valve core of main valve 12, and the lower end of valve core of main valve 12 is provided with damping hole 13, and valve core of main valve 12 is pacified
In valve body of main valve 14.
A kind of operation principle of the embodiment of magnetorheological pilot-operated overflow valve of the utility model is：During work, when
During 6 no power of magnet coil of magnetic flow liquid pilot valve, the working clearance that magnetic flow liquid is flowed through, magnetic flow liquid was not by magnetic without magnetic field
The effect of field damping force, can freely be flowed through in the pilot valve of magnetic flow liquid pilot operated compound relief valve.If magnetic flow liquid pilot valve
When magnet coil 6 is powered, by electromagnetic induction, magnetic induction line passes through " day " font cylinder damp channel, the direction of magnetic induction line and magnetic
The flow direction of rheology liquid is vertical, magnetic flow liquid when by " day " font passage, the magnetic suspension particle of magnetic flow liquid by
Magnetic field act on and quickly form the catemer arranged along magnetic direction, the viscosity of magnetic flow liquid increases rapidly, and with
The increase of impressed current and increase so that magnetic flow liquid is changed into the Bingham fluid of solid-state from the Newtonian fluid originally flowed freely.
When impressed current increases to certain value, when magnitude of pressure differential of the magnetic flow liquid in pilot valve can not overcome the active force in magnetic field,
Just can not be by the pilot valve of magnetic flow liquid pilot operated compound relief valve, then the pilot valve core 7 of magnetic flow liquid pilot operated compound relief valve
It is closed, now the pressure differential at magnetic flow liquid pilot valve two ends can reach maximum.Artificial regulation electricity can be passed through
The size of the electric current of magnetic coil 6 sets the set pressure value of pilot valve, if inlet pressure is less than the set pressure of pilot valve, magnetic current
Becoming liquid can not be just closed by " day " font damp channel, main valve, it is impossible to overflow, now inlet pressure, magnetorheological
Pilot valve left end pressure and main valve upper cavity pressure are equal.If inlet pressure is more than the set pressure of pilot valve, magnetic flow liquid is entering
It can overcome the active force in magnetic field in the presence of mouth pressure, flow through the pilot valve of magnetic flow liquid pilot operated compound relief valve, a left side for pilot valve
End is equal with the upper cavity pressure of main valve, and the flowing of magnetic flow liquid can cause the upper cavity pressure of pilot valve left end and main valve in pilot valve
Reduce, additionally, due to the damping action of main valve plug damping hole 13 so that the upper cavity pressure of main valve is significantly less than inlet pressure, therefore
Valve core of main valve 12 rises in the presence of pressure differential, and overflow phenomena occurs for magnetic flow liquid.
