Description
Technical field
The present invention relates to a kind of improvement invention of overflow valve, relate in particular to the improvement invention of the spacing overflow valve of a kind of automotive oil tank oiling.
Background technology
The spacing overflow valve of automotive oil tank oiling, comprise valve body, valve gap, spool, check-valves and non-return valve seat, be mainly used in when overflow valve is during in Difference angles, can spool change and in valve body, rise or decline with gravity and buoyancy, control fuel oil and whether enter valve body, effectively avoided automobile to overturn and cause fuel tank leakage of oil enlargement loss because of accident simultaneously. In prior art, the contact area of spool and valve body is larger, has increased frictional force, has affected the sensitivity that spool moves in valve body; When spool is fit into valve body simultaneously, easily displacement makes to occur loading error.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, install accurately, the cost of material is low, and the spacing overflow valve of automotive oil tank oiling that rubs little between spool and valve body.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme to realize: this kind of spacing overflow valve of automotive oil tank oiling, comprise the check-valves being arranged in valve body, non-return valve seat and spool, described valve body is provided with valve gap, valve gap is provided with oil-in, described check-valves is arranged on non-return valve seat, and check-valves and valve gap oil-in match, described non-return valve seat can longitudinally rotate and be arranged on spool upper end, it is characterized in that: described spool is hollow setting, and opening is established in spool lower end, opening part is sealed by a spool lower cover, described spool lower cover is connected by spring with valve body inner bottom part, described spool outer wall is provided with some the reinforcements that longitudinally arrange, and the contact-making surface of this reinforcement is rounding setting, and described spool outer wall is also provided with installation gib block, and described valve interior wall is provided with the gathering sill matching with this installation gib block.
Under described spool inwall and spool, cover and be provided with the groove and the flange that match, and both are sealed and matched by hard button interference.
Described spool and spool lower cover adopt POM material, and described check-valves is rubber check valve.
Between described spool and non-return valve seat, be provided with anti-laminating projection, this anti-laminating projection is arranged on spool upper end or the non-return valve seat back side.
Described spool lower cover bottom is provided with draw-in groove, and valve body bottom is provided with sleeve pipe, and described spring one end is arranged in draw-in groove, and the other end is arranged on sleeve pipe.
The invention has the beneficial effects as follows the spacing overflow valve of automotive oil tank oiling after improvement, at spool outer wall design reinforcement, can effectively reduce the frictional force between spool and valve body, valve hole part is moved flexibly in valve body; Spool outer wall design and installation gib block, while making spool be installed into valve body quick and precisely; Spool and spool lower cover adopt POM material effectively to substitute original foamed plastic, when meeting valve hole part and have certain gravity and buoyancy proportioning, have saved Development and Production cost.
Brief description of the drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is valve core structure schematic diagram of the present invention.
Fig. 3 is the A-A schematic diagram of Fig. 1.
Detailed description of the invention
Accompanying drawing has represented structure of the present invention, further illustrates by reference to the accompanying drawings its details below again. The spacing overflow valve of this automotive oil tank oiling, comprise the check-valves 2, non-return valve seat 3 and the spool 4 that are arranged in valve body 1, described valve body 1 is provided with valve gap 6, valve gap 6 is provided with oil-in, described check-valves 2 is arranged on non-return valve seat 3, and check-valves 2 matches with valve gap 6 oil-ins, described non-return valve seat 3 can longitudinally rotate and be arranged on spool 4 upper ends, described spool 4 is hollow setting, and opening is established in spool 4 lower ends, opening part is sealed by a spool lower cover 5, and described spool lower cover 5 is connected by spring 7 with valve body 1 inner bottom part; Described spool 4 outer walls are provided with some the reinforcements 8 that longitudinally arrange, and the contact-making surface of this reinforcement 8 is smooth rounding setting, and described spool 4 outer walls are also provided with installs gib block 9, and described valve body 1 inwall is provided with the gathering sill 11 matching with this installation gib block 9. Described non-return valve seat 3 one side direction downward-extensions connect a turning cylinder, described turning cylinder is arranged in the indent of spool 4 upper end one sides, in indent, be provided with the pedestal of coupling and the barb of restriction turning cylinder disengaging indent, the gib head of this barb is arranged in the recess on the extended surface of described non-return valve seat 3 one side direction downward-extensions, and described turning cylinder is provided with the limited block that limits corner. Described spool 4 inwalls and spool lower cover 5 are provided with the groove and the flange that match, and both are sealed and matched by hard button interference. Described spool 4 adopts POM material with spool lower cover 5, and described check-valves 2 is rubber check valve.
