Abstract
The utility model discloses a kind of liquid current control one-way valve, comprise valve seat, in valve seat, be provided with the first cavity and the second cavity, the first cavity communicates with the second cavity, between the first cavity and valve seat, be provided with filler opening, between the second cavity and valve seat, be provided with oil outlet, in the second cavity, be provided with the first spring, first spring one end is fixedly connected on valve seat, the first spring the other end and taper valve core are fixedly linked, in taper valve core, center is provided with ladder hole, in ladder hole, be provided with the second spring, second spring one end is fixedly connected on the ladder surface in ladder hole, the second spring the other end and steel ball are fixedly linked.The utility model makes, no matter how fluid flows to, to have remained one-way flow on flow direction.
Description
Technical field
The utility model relates to a kind of one-way valve, especially a kind of liquid current control one-way valve.
Background technique
When one-way valve uses in hydraulic system, being mainly the effect of starting to control liquefaction liquid one-way flow, for this reason, is not generally to be arranged in migration pipeline, in case fluid cannot be back to fuel tank smoothly, causes system to block.In the time must arranging in some migration pipeline, when oil return also separately establish pipeline and get around one-way valve.Therefore, be subject to narrow limitation larger, easily make hydraulic system become complicated.
Model utility content
For solving the problems of the technologies described above, it is a kind of no matter how fluid flows to that the utility model provides, and remains the liquid current control one-way valve of one-way flow on flow direction.
For achieving the above object, the technical solution of the utility model is: a kind of liquid current control one-way valve, comprise valve seat, in valve seat, be provided with the first cavity and the second cavity, the first cavity communicates with the second cavity, between the first cavity and valve seat, be provided with filler opening, between the second cavity and valve seat, be provided with oil outlet, in the second cavity, be provided with the first spring, first spring one end is fixedly connected on valve seat, the first spring the other end and taper valve core are fixedly linked, in taper valve core, center is provided with ladder hole, in ladder hole, be provided with the second spring, second spring one end is fixedly connected on the ladder surface in ladder hole, the second spring the other end and steel ball are fixedly linked.
The beneficial effects of the utility model are: no matter how fluid flows to, remained one-way flow on flow direction.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: valve seat 1, the first cavity 21, the second cavity 22, filler opening 3, oil outlet 4, the first spring 51, the second spring 52, taper valve core 6, ladder hole 7, ladder surface 71, steel ball 8.
Embodiment
Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.
Embodiment:
As shown in Figure 1, a kind of liquid current control one-way valve, comprise valve seat 1, in valve seat 1, be provided with the first cavity 21 and the second cavity 22, the first cavity 21 communicates with the second cavity 22, between the first cavity 21 and valve seat 1, be provided with filler opening 3, between the second cavity 22 and valve seat 1, be provided with oil outlet 4, in the second cavity 22, be provided with the first spring 51, first spring 51 one end are fixedly connected on valve seat 1, first spring 51 the other ends and taper valve core 6 are fixedly linked, the interior center of taper valve core 6 is provided with ladder hole 7, in ladder hole 7, be provided with the second spring 52, second spring 52 one end are fixedly connected on the ladder surface 71 in ladder hole 7, second spring 52 the other ends and steel ball 8 are fixedly linked.
Working principle of the present utility model is: in the time that fluid enters from filler opening 3, oil pressure overcomes the elastic pressure of the first spring 51, forces taper valve core 6 to move backward, thereby fluid is flowed out from space, realizes normal one-way flow; In the time that fluid enters from oil outlet 4, oil pressure overcomes the elastic pressure of the second spring 52, forces steel ball 8 to move backward, thereby fluid is flowed out through ladder hole 7 from space.Like this, no matter how fluid flows to, on flow direction, also just remained one-way flow.
