Abstract
The utility model discloses a steel ball type turnover valve, and relates to the technical field of automobiles. The steel ball type turnover valve comprises a valve seat, a valve element, a steel ball, a valve cover, an air inlet, a sealing surface, an air cutting port, a guide inclined surface and an air outlet, the air inlet is formed in the center of the top of the valve seat, the valve element is arranged inside the valve seat, the valve element is matched with the steel ball, the valve cover is arranged below the steel ball, the valve cover is matched with the bottom of the valve seat, the guide inclined surface is arranged on the inner side of the valve cover, the guide inclined surface is matched with the steel ball, the air outlet is formed in the guide inclined surface, an air cutting port is formed between the air inlet and the valve element, and the sealing surface is arranged outside the air inlet. According to the steel ball type turnover valve, leakage risks caused by overturn accidents are reduced, deformation cannot be generated, the service life is longer, and the effect is better.
Description
Technical field
The utility model relates to automobile technical field, be specifically related to a kind of steel ball type turning-over valve.
Background technique
Fuel pump is when extracting oil out the use of fuel tank supply engine, and fuel tank internal air pressure need to be consistent with the outer air pressure of fuel tank, otherwise air pressure can stop oil in fuel tank to be sucked out, cannot normal fuel injection.So need an energy and the hole of the outer UNICOM of fuel tank to ventilate on fuel tank, make fuel tank inner and outer air pressure consistent.But gasoline is quite dangerous, once run in automobile running after the inclination of overturn accident or automobile several angle, the oil in fuel tank will flow out and cause danger from this vent.And when turning-over valve is contained on this vent, after tilting of automobile several angle, turning-over valve can automatically be closed vent and be prevented that gasoline from flowing out.When automobile recurrence is normally travelled, turning-over valve is opened automatically, and it is consistent that vent continuation ventilation maintains inner and outer air pressure.Thereby reduce the risk that in fuel tank, gasoline flows out.
But the structure of traditional turning-over valve is not compact, still easily cause leakage, and the also easily generation distortion of traditional turning-over valve, working life is short.
Model utility content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of steel ball type turning-over valve, has reduced the leakage danger that overturn accident causes, and can not produce distortion, longer service life, better effects if.
To achieve these goals, the utility model is to realize by the following technical solutions: steel ball type turning-over valve, comprise valve seat, spool, steel ball, valve gap, suction port, sealing surface, cut gas port, guiding surface and air outlet, valve seat top center is provided with suction port, valve seat inside is provided with spool, spool matches with steel ball, steel ball below is provided with valve gap, valve gap matches with valve seat bottom, valve gap inner side is guiding surface, guiding surface matches with steel ball, on guiding surface, be provided with air outlet, between suction port and spool, be provided with and cut gas port, suction port arranged outside has sealing surface.
The beneficial effects of the utility model:
1, closing angle that just can stable and accurate change turning-over valve by adjustable inclined surface apparatus angle
2, sealing surface and interface interference fit, play fixedly double action of sealing case, makes the compact structure of valve, reduced multi-part and coordinate because coordinating the risk of leakage causing not in place
3, use steel ball rely on from reopening or promote the principle that spool is closed, make the open and close action of valve sensitiveer
4, conventional construction steel ball type turning-over valve can not produce permanent deformation relatively, and it is longer that steel ball type turning-over valve is stablized the life-span more.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1, this embodiment is by the following technical solutions: steel ball type turning-over valve, comprise valve seat 1, spool 2, steel ball 3, valve gap 4, suction port 5, sealing surface 6, cut gas port 7, guiding surface 8 and air outlet 9, valve seat 1 top center is provided with suction port 5, valve seat 1 inside is provided with spool 2, spool 2 matches with steel ball 3, steel ball 3 belows are provided with valve gap 4, valve gap 4 matches with valve seat 1 bottom, valve gap 4 inner sides are guiding surface 8, guiding surface 8 matches with steel ball 3, on guiding surface 8, be provided with air outlet 9, between suction port 5 and spool 2, be provided with and cut gas port 7, suction port 5 arranged outside have sealing surface 6.
The working principle of this embodiment: 1, under normal state, turning-over valve is upright, overturning spool and steel ball rely on the gravity fall of self, and overturning valve gap is held.Overturning spool becomes certain distance with a section gas port, cuts gas port and opens.Air enters in valve by suction port, then enters in fuel tank from air outlet.(when fuel tank is had in vain, automobile fuel filler is just contrary, and the air that is mingled with gasoline in fuel tank enters from air outlet, from suction port, goes out)
2,, when tilting of automobile several angle, steel ball relies on self gravitation movable along guiding surface.It is movable that the activity of steel ball promotes overturning spool, but overturning spool is fixed on the shaft axis of suction port, so can only be along suction port axial-movement.When steel ball moves along inclined-plane, pushing away overturning spool and causing when cutting gas port laminating, ventilating hole sealing, oil cannot flow out fuel tank by ventilating hole.When steel ball moves along inclined-plane, to air outlet axial direction, moved L2, steel ball is along inclined-plane move distance L1, and inclined-plane angle a is L2=L1COSa/2, can adjust the inclination closing angle of turning-over valve by changing inclined-plane angle.
This embodiment has reduced the leakage danger that overturn accident causes, and can not produce distortion, longer service life, better effects if.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
