Abstract
The utility model discloses a manual control check valve which comprises a valve seat. A first cavity is arranged in the valve seat, a spring is arranged in the first cavity, one end of the spring is fixedly connected to the valve seat, the other end of the spring is fixedly connected with a conical valve element, a second cavity is arranged in the valve seat, a cam is arranged in the second cavity, a hand crank is fixedly connected at the position, deviating from the center, of the cam, the hand crank penetrates through a bearing on the valve seat, an oil inlet communicated with the second cavity and an oil outlet communicated with the first cavity are formed in the valve seat, a flow channel is arranged between the first cavity and the second cavity, and the diameter of the flow channel is larger than the maximum diameter of the cam. The manual control check valve carries out one-way flowing in a normal state, when oil needs to flow oppositely, control can be achieved simply by rotating the hand crank hard, and the manual control check valve is flexible and convenient to use, and large in application range.
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 uses in hydraulic system, mainly being the effect of starting to control liquefaction liquid one-way flow, for this reason, generally is 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 must arranging in some migration pipeline, during oil return also establish in addition pipeline and get around one-way valve.Therefore, be subjected to narrow limitation larger, easily so that the hydraulic system 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, as long as firmly rotary handle crank can be realized the manual control one-way valve controlled.
For achieving the above object, the technical solution of the utility model is: a kind of manual control one-way valve, comprise valve seat, be provided with the first cavity in the valve seat, be provided with spring in the first cavity, spring one end is fixedly connected on the valve seat, the spring the other end and taper valve core are fixedly linked, be provided with the second cavity in the valve seat, in the second cavity cam arranged, cam is fixedly connected with wind departing from the center, wind passes the bearing on the valve seat, valve seat is provided with the filler opening that is connected with the second cavity and the oil outlet that is connected with the first cavity, is provided with runner between the first cavity and the second cavity, and Flow diameter is greater than the cam maximum diameter.
The beneficial effects of the utility model are: be one-way flow under the normal state, when needs fluid reverse flow, the rotary handle crank that only needs to exert oneself can be realized control, and flexible, application area is large.
Description of drawings
Fig. 1 is the structural representation of cam when not contacting with taper valve core;
Fig. 2 is the structural representation of cam when backing down taper valve core;
Fig. 3 is the connection diagram between cam and the wind.
Among the figure: valve seat 1, the first cavity 21, the second cavity 22, spring 3, taper valve core 4, cam 5, wind 6, bearing 7, filler opening 8, oil outlet 9, runner 10.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
Such as Fig. 1, shown in Figure 2, a kind of manual control one-way valve, comprise valve seat 1, be provided with the first cavity 21 in the valve seat 1, be provided with spring 3 in the first cavity 21, spring 3 one ends are fixedly connected on the valve seat 1, spring 3 the other ends and taper valve core 4 are fixedly linked, being provided with in the valve seat 1 in the second cavity 22, the second cavitys 22 has cam 5, and cam 5 is fixedly connected with wind 6 departing from the center, wind 6 passes the bearing 7 on the valve seat 1, valve seat 1 is provided with between the filler opening 8 that is connected with the second cavity 22 and oil outlet 9, the first cavitys 21 that are connected with the first cavity 21 and the second cavity 22 and is provided with runner 10, and runner 10 diameters are greater than cam 5 maximum diameters.
Working principle of the present utility model is: rotary handle crank 6, and is the same with common one-way valve when cam 5 does not contact with taper valve core 4, and hydraulic oil can only flow to oil outlet 9 through filler opening 8, can not reverse flow; Rotary handle crank 6 when going to several angle, backs down taper valve core 4 by cam 5, and filler opening 8 and oil outlet 9 are connected, and at this moment, fluid just can have been realized reverse flow.
