The invention relates to a steel ball type overturn valve which comprises an overturn valve base, a seal sleeve, an overturn valve core, a steel ball and an overturn valve cover, wherein the seal sleeve is provided with an air inlet; the overturn valve cover is provided with an air outlet communicated with an air inlet of the seal sleeve; the air inlet is internally provided with an air check port; the overturn valve core is provided with a check end surface by corresponding to the air check port; the bottom of the overturn valve core props against the steel ball; the caliber of an opening of the steel ball corresponding to the cavity of the overturn valve core is less than that of the diameter of the steel ball; the steel ball is positioned on the overturn valve cover which is provided with a steel ball guide surface. Under a normal state, the overturn valve is upright, the overturn valve core and the steel ball fall down due to self gravity and are supported by the overturn valve cover; a certain distance exists between the overturn valve core and the air check port, and the air check port is opened; When an automobile is inclined laterally, the steel ball rolls due to the gravity so as to extrude the overturn valve core to move upward, so that the distance between the overturn valve core and the air check port is shortened, the ventilating area of the air check port is reduced until the distance between the overturn valve core and the air check port is shortened and the overturn valve core and the air check port are combined, the cavity of the overturn valve core is plugged by the steel ball and a secondary plugging effect is achieved.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of steel ball type overturning valve.
Background technique
Fuel pump is when extracting fuel tank supply engine out and using by oil, fuel tank internal air pressure needs 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 fuel tank needs the hole of the outer UNICOM of an energy and fuel tank ventilate, make fuel tank inner and outer air pressure consistent.But gasoline is quite dangerous, once after running into the inclination of overturn accident or automobile several angle in automobile running, the oil in fuel tank will flow out from this vent and cause danger.
Summary of the invention
For solving the problem, the object of the present invention is to provide a kind of avoid running in automobile running the inclination of overturn accident or automobile several angle after, reduce the steel ball type overturning valve that gasoline flows out in fuel tank.
For achieving the above object, the invention provides following technological scheme: a kind of steel ball type turning-over valve, comprise overturning valve seat, stuffing box gland, overturning spool, steel ball, overturning valve gap, described overturning valve base inner wall and described stuffing box gland are sealed and matched, described overturning seat bottom portion is connected and described overturning valve gap, described stuffing box gland is provided with suction port, described turning-over valve is covered with the air outlet communicated with the suction port on described stuffing box gland, be provided with in described suction port and cut gas port, described cutting below gas port is provided with overturning spool chamber, described overturning spool cavity wall correspondence and described turning-over valve outer core, described in described overturning spool correspondence, a section gas port is provided with and intercepts end face, described steel ball is connected to bottom described overturning spool, the opening bore of the corresponding steel ball of described overturning spool chamber is less than described steel ball size, described steel ball is positioned at described turning-over valve and covers, described turning-over valve covers and is provided with steel ball guide surface.
By adopting technique scheme, under normal state, turning-over valve is upright, the gravity fall of overturning spool and steel ball dependence self, and overturning valve gap is held.Overturning spool becomes certain distance with a section gas port, cuts gas port and opens.Air is entered in valve by suction port, then enters in fuel tank from air outlet.When automobile roll, steel ball moves upward by gravity rolling extruding overturning spool, and overturning spool is reduced the distance with a section gas port, cause cutting gas port breathing area to reduce, until overturning spool and a section gas port shorten closed, now steel ball also plugs overturning spool chamber, serves the effect of secondary blocking.
The inwall of described overturning spool chamber is provided with guide surface, and on described guide surface, bending goes out a sealing surface, and the described sealing surface described in overturning spool correspondence is provided with seal face.
By adopting technique scheme, making the sealing surface in overturning spool chamber and the seal face closing seam on overturning spool, playing the second effect heavily blocked.
Described overturning spool is the Pagoda-shaped that double cylinder is formed, and described seal face is located between upper and lower cylindrical body, and described seal face is taper, and described end face of intercepting is located at upper strata cylinder top end, and described end face of intercepting is taper.
By adopting technique scheme, sealing surface is taper, and serve and increase sealing contact surface thus improve blocking effect, intercepting end face is taper, and a section gas port is circular hole, thus serves guarantee section gas port blocking.
A described section gas port is circle hole shape, and described overturning spool central axis and described section gas port central axis are on the same axis.
By adopting technique scheme, making overturning spool along axial-movement in overturning spool chamber, further having ensured the blocking effect of intercepting end face and sealing surface.
The described steel ball described in stuffing box gland inwall correspondence is provided with guide seal cover.
By adopting technique scheme, during automobile overturning, steel ball is affected by gravity, and can carry out triple blocking along pilot seal in the face of turning-over valve core chamber.
Described guide seal cover connects the tapered extension of described overturning spool chamber lower ending opening.
By adopting technique scheme, during automobile overturning, steel ball slides into overturning spool chamber lower ending opening along the conical surface, decreases resistance, the accuracy of the blocking of increase.
The guide surface that described turning-over valve covers is the direction conical surface down, and described steel ball is active on the described conical surface by gravity.
By adopting technique scheme, when tilting of automobile, steel ball is affected by gravity the guide surface covered along turning-over valve and moves, and steel ball extruding overturning spool moves upward, shorten and the distance of cutting gas port, reduce and cut gas port breathing area, thus play the effect automatically adjusting section gas port breathing area according to tilting of automobile degree.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
