Abstract
The utility model discloses a manual control one-way valve which comprises a valve seat. A first cavity is formed in the valve seat. A spring is arranged in the first cavity. One end of the spring is fixedly connected to the valve seat and the other end of the spring is fixedly connected with a conic valve element. A threaded hole and a second cavity are sequentially formed between the valve seat and the first cavity. The threaded hole is connected with a pushing rod. Threads are arranged at the tail end of the pushing rod. The first cavity is communicated with the second cavity. An oil inlet is formed between the first cavity and the valve seat. An oil outlet is formed between the second cavity and the valve seat. When the manual control one-way valve is under the common state, oil flows in one direction; when the oil needs to flow back, the pushing rod is screwed inwards with force so that control can be achieved. The manual control one-way valve is flexible, convenient to use and large in the range of application.
Description
Technical field
The utility model relates to a kind of one-way valve, especially a kind of manual control one-way valve.
Background technique
When one-way valve is used in hydraulic system, being mainly the effect of starting to control liquefaction liquid one-way flow, for this reason, is generally not to be arranged in the migration pipeline, in case fluid can't be back to fuel tank smoothly, causes system to block.In the time in some migration pipeline, must arranging, during oil return also separately establish pipeline and get around one-way valve.Therefore, be subjected to narrow limitation larger, easily make hydraulic system become complicated.
The model utility content
For solving the problems of the technologies described above, it is one-way flow that the utility model provides under a kind of normal state, when needs fluid reverse flow, can realize as long as firmly screw inward push rod the manual control one-way valve of controlling.
For achieving the above object, the technical solution of the utility model is: a kind of manual control one-way valve, comprise valve seat, in valve seat, be provided with the first cavity, in the first cavity, be provided with spring, spring one end is fixedly connected on valve seat, the spring the other end and taper valve core are fixedly linked, between valve seat and the first cavity, be provided with successively tapped hole, the second cavity, on tapped hole, be connected with push rod, the push rod end is threaded, and the first cavity communicates with the second cavity, between the first cavity and valve seat, be provided with filler opening, be provided with oil outlet between the second cavity and valve seat.
The beneficial effects of the utility model are: under normal state, be one-way flow, when needs fluid reverse flow, can realize controlling as long as firmly screw inward push rod, flexible, application area is large.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: valve seat 1, the first cavity 21, the second cavity 22, spring 3, taper valve core 4, tapped hole 5, push rod 6, filler opening 7, oil outlet 8.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of manual control one-way valve, comprise valve seat 1, in valve seat 1, be provided with the first cavity 21, in the first cavity 21, be provided with spring 3, spring 3 one ends are fixedly connected on valve seat 1, spring 3 the other ends and taper valve core 4 are fixedly linked, between valve seat 1 and the first cavity 21, be provided with successively tapped hole 5, the second cavity 22, on tapped hole 5, be connected with push rod 6, push rod 6 ends are threaded, and the first cavity 21 communicates with the second cavity 22, between the first cavity 21 and valve seat 1, be provided with between filler opening 7, the second cavitys 22 and valve seat 1 and be provided with oil outlet 8.
Working principle of the present utility model is: when not screwing push rod 6 inward, push rod 6 does not contact with taper valve core 4, the same with common one-way valve, and hydraulic oil can only flow to oil outlet 8 through filler opening 7, can not reverse flow; When firmly screwing inward push rod 6, while being threaded to certain process, back down taper valve core 4 by push rod 6, filler opening 7 and oil outlet 8 are connected, at this moment, fluid just can have been realized reverse flow.
