Description
技术领域technical field
本实用新型涉及一种双向作用的流量控制阀，这种流量控制阀能通过控制磁场强度实现流量的连续控制和开阀压力的大小的控制，而且共用一套线圈实现两个作用方向的压力控制，也可作为两个单向流量控制阀。The utility model relates to a two-way acting flow control valve.

背景技术Background technique
阻尼器广泛使用在减振系统中，阻尼器的阀系是其设计关键，传统的机械式阀系是通过阀片的叠加来实现流量的控制。缺点是阀系设计复杂，设计完毕后对流量的控制规则不易改变，且相应的阀片开启时流量出现波动。随着科学技术的发展，阻尼器向智能化、精密化的方向发展，这就要求我们设计更加精确的阀系来实现流量的精准控制。Dampers are widely used in vibration reduction systems. The valve system of the damper is the key to its design. The traditional mechanical valve system realizes flow control through the superposition of valve plates. The disadvantage is that the design of the valve system is complex, the flow control rules are not easy to change after the design is completed, and the flow fluctuates when the corresponding valve plate is opened. With the development of science and technology, the damper is developing in the direction of intelligence and precision, which requires us to design a more precise valve system to achieve precise flow control.
磁流变弹性体在磁场的作用下表现为线性粘弹性体的动力学特性，即其性能介于线性弹性体和线性粘性体流体之间。使用磁流变固体材料的明显优点是颗粒不会随时间而沉降,也不需要将磁流变材料保持在工作位置的密封装置。Under the action of a magnetic field, the magnetorheological elastomer exhibits the dynamic characteristics of a linear viscoelastic body, that is, its performance is between that of a linear elastic body and a linear viscous fluid. The obvious advantage of using a magnetorheological solid material is that the particles do not settle over time and no seals are required to keep the magnetorheological material in place.
