Abstract

The invention relates to a pressure control valve, in particular to a magnetorheological pressure control valve for achieving hydraulic system pressure control through a force required to start the control valve. The pressure control valve comprises an inner valve body, a valve core, a blanking cap, a main valve body, a working chamber containing magnetorheological fluid, a coil assembly composed of a coil and a magnet separation jacket, an outer valve body, an upper valve body, a thrust shaft, a spring seat, a reset spring, an end cap, a travel switch sensor and a plurality of rubber seal rings. The magnetorheological pressure control valve is simple in structure, convenient to manufacture, high in energy efficiency and quick in pressure response and stepless and intelligent control of system pressure can be achieved.

Description

technical field [0001] The invention relates to a pressure control valve, in particular to a magneto-rheological pressure control valve which realizes pressure control of a hydraulic system by controlling the force required when the valve is opened. Background technique [0002] Common pressure control valves usually control the system pressure by controlling the preload of the spool spring. Traditional pressure control valves control the pre-tightening force of the control spool spring by changing the magnetic field of the electromagnetic coil, thereby changing the force required for the spool to open, and then controlling the system pressure. In the traditional design, the machining accuracy is high, and the product consistency is poor; the requirements for the valve core spring are very high, and it is not easy to realize the rapid and stepless pressure change; the valve core movement is generally small; the power consumption is very low. Large and not energy efficient. ...
