Two-way flow control valve

Abstract

The invention discloses a two-way flow control valve. The two-way flow control valve comprises an upper valve body 2 and a lower valve body 11 which are coaxially and fixedly connected with each other. An upper valve core 1, an upper thrust bar 3 and an upper inner valve body 4 are sequentially installed in the upper valve body 2 from top to bottom. A lower thrust bar 12, a lower inner valve body 10, a coil 6 and a non-magnetic sleeve 7 are sequentially and coaxially installed in the lower valve body 11 from bottom top, and the coil 6 and the non-magnetic sleeve 7 are arranged in a nested mode. An upper pole plate 16, a magnetorheological elastomer 8 and a lower pole plate 15 are sequentially installed in the non-magnetic sleeve 7 and located between the upper thrust bar 3 and the lower thrust bar 12 from top to bottom. The two-way flow control valve is further provided with two oil inlet and oil outlet sets. By means of the two-way flow control valve, continuous control over flow and control over valve opening pressure can be achieved by controlling magnetic field intensity, and the valve opening pressure can be changed according to external use conditions; besides, two-way pressure control is achieved through one coil, and therefore the two-way flow control valve can serve as two one-way flow control valves; the two-way flow control valve is high in response speed and wide in pressure control range.

Description

Technical field [0001] The invention relates to a two-way flow control valve, which can realize continuous flow control and valve opening pressure control by controlling the intensity of a magnetic field, and a set of coils are shared to realize pressure control in two directions of action. It can also be used as two one-way flow control valves. Background technique [0002] 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 valve system design is complicated, 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 dampers are developing in the direction of intelligence and precision, which requires us to design more precise valve systems to achi...
