Description
Technical field
The present invention relates to a kind of improvement invention of relief valve, particularly relate to the improvement invention of the spacing relief valve of a kind of automotive oil tank oiling.
Background technique
The spacing relief valve of automotive oil tank oiling, comprise valve body, valve gap, spool, safety check and Boilor check valve seat, be mainly used in when relief valve is in Difference angles, can spool change with gravity and buoyancy and rise in valve body or decline, control fuel oil and whether enter valve body, effectively avoid automobile simultaneously and overturn because of accident and cause fuel tank leakage of oil and enlargement loss.In prior art, the area of contact of spool and valve body is comparatively large, increases frictional force, have impact on the sensitivity of spool movement in valve body; Easily be shifted when spool is fit into valve body simultaneously and make to occur loading error.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provide a kind of rational in infrastructure, install accurately, the cost of material is low, and the spacing relief valve of automotive oil tank oiling rubbing little between spool and valve body.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme to realize: this kind of spacing relief valve of automotive oil tank oiling, comprise the safety check be arranged in valve body, Boilor check valve seat and spool, described valve body is provided with valve gap, valve gap is provided with filler opening, described safety check is arranged on Boilor check valve seat, and safety check and valve gap filler opening match, described Boilor check valve seat longitudinally can rotate and be arranged on spool upper end, it is characterized in that: described spool is that hollow is arranged, and opening is established in spool lower end, opening 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 stiffening ribs longitudinally arranged, and the surface of contact of this stiffening rib is that rounding is arranged, and described spool outer wall is also provided with installation gib block, and described valve interior wall is provided with the guiding groove matched with this installation gib block.
Cover the groove and flange that are provided with and match under described spool inwall and spool, and both are coordinated by hard button interference seal.
Described spool and spool lower cover adopt POM material, and described safety check is rubber check valve.
Be provided with anti-projection of fitting between described spool and Boilor check valve seat, this anti-laminating projection is arranged on spool upper end or the Boilor check valve seat back side.
Be provided with draw-in groove bottom described spool lower cover, body base 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 relief valve of automotive oil tank oiling after improvement, at spool outer wall design stiffening rib, the frictional force between spool and valve body can be effectively reduced, make valve hole part movement flexibly in valve body; Spool outer wall design and installation gib block, when making spool be installed into valve body quick and precisely; Spool and spool lower cover adopt POM material effectively to instead of original expandable plastic, meet while valve hole part has certain gravity and buoyancy proportioning, have saved Development and Production cost.
Accompanying drawing explanation
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.
Embodiment
Drawings illustrate structure of the present invention, further illustrate its details by reference to the accompanying drawings more below.The spacing relief valve of this automotive oil tank oiling, comprise the safety check 2 be arranged in valve body 1, Boilor check valve seat 3 and spool 4, described valve body 1 is provided with valve gap 6, valve gap 6 is provided with filler opening, described safety check 2 is arranged on Boilor check valve seat 3, and safety check 2 and valve gap 6 filler opening match, described Boilor check valve seat 3 longitudinally can rotate and be arranged on spool 4 upper end, described spool 4 is hollow setting, and opening is established in spool 4 lower end, opening 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 wall is provided with some the stiffening ribs 8 longitudinally arranged, and the surface of contact of this stiffening rib 8 is that smooth rounding is arranged, and described spool 4 outer wall is also provided with installs gib block 9, and described valve body 1 inwall is provided with the guiding groove 11 matched with this installation gib block 9.Described Boilor check valve seat 3 side connects a rotatingshaft to downward-extension, described rotatingshaft is arranged in the indent of side, spool 4 upper end, the pedestal of coupling and the barb of restriction rotatingshaft disengaging indent is provided with in indent, the gib head of this barb is arranged on described Boilor check valve seat 3 side in the recess on the extended surface of downward-extension, and described rotatingshaft is provided with the limiting stopper limiting corner.Described spool 4 inwall and spool lower cover 5 are provided with the groove and flange that match, and both are coordinated by hard button interference seal.Described spool 4 adopts POM material with spool lower cover 5, and described safety check 2 is rubber check valve.Be provided with anti-projection 10 of fitting between described spool 4 and Boilor check valve seat 3, this anti-laminating protruding 10 is arranged on spool 4 upper end or Boilor check valve seat 3 back side, can effectively prevent Boilor check valve seat 3 to be difficult to be separated because be infected with after fluid is fitted with spool 4 upper end.Be provided with draw-in groove bottom described spool lower cover 5, be provided with sleeve pipe bottom valve body 1, described spring 7 one end is arranged in draw-in groove, and the other end is arranged on sleeve pipe.
