Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, the present invention is a kind of check valve based on magneto-rheological effect. 8, sealing ring 9, spool 10 are formed. The valve body 1, the valve sleeve 3 and the valve end cover 6 are fixed by bolts 2; the valve core 10 has an oil circuit 5 inside and a ring groove on the outside, and the electromagnetic coil 4 is wound in this ring groove; the valve core 10 and the valve The sleeve 3 forms a gap fit, the gap is filled with magnetorheological fluid 7, and is sealed by a sealing ring 9, and the magnetorheological fluid 7 and the electromagnetic coil 4 are separated by an isolation ring 8; both ends of the valve sleeve 3 are provided with ring grooves inside, The sealing ring 9 is embedded in the ring groove inside.

[0013] The electromagnetic coil 4 passes a current with a certain intensity, so that ...

Abstract

The invention relates to a magnetorheological-effect-based check valve. The check valve is mainly used for control over oil flowing direction in a precise hydraulic control system and on-off of an oil channel. The check valve comprises a valve body, a bolt, a valve sleeve, an electromagnetic coil, a valve end cover, magnetorheological fluid, a separation ring, seal rings and a valve core. The valve body, the valve sleeve and the valve end cover are fixed through the bolt. The oil channel is formed in the valve core. The outside of the valve core is provided with an annular groove. The electromagnetic coil is wound in the annular groove. The valve core is in clearance fit with the valve sleeve. The clearance of the valve core and the valve sleeve is filled with the magnetorheological fluid and sealed by the seal rings. The magnetorheological fluid and the electromagnetic coil are separated by the separation ring. Annular grooves are formed in the inner sides of the two ends of the valve sleeve, and the seal rings are embedded in the annular grooves.

Description

technical field [0001] The invention relates to a one-way valve, in particular to a one-way valve based on the magneto-rheological effect. Background technique [0002] Hydraulic actuator systems are not only widely used in civil machining, vehicles and construction industries, but also in aerospace, aviation and military products. As one of the core control units of the hydraulic actuator, the hydraulic control valve has been directly affecting the static characteristics, dynamic characteristics and working reliability of the hydraulic actuator. Due to the existence of many moving mechanical parts inside the traditional hydraulic control valve, not only the structure is complex, the volume is large, the processing requirements are high, the wear is easy, the cost is high, but also there are problems such as difficult control, slow response, loud working noise and low working reliability. question. Therefore, seeking a hydraulic control valve with simple structure, reliabl...
