Description
Technical field
The utility model is related to a kind of fuel tank cap.Specifically, it is buffer-type fuel tank at hydraulic workstation tank drainback mouth
Oil return lid.
Background technology
It is both known about in machinery industry, is both provided with greatly for the fuel tank for its service in hydraulic system, is all arranged on fuel tank
There are oil outlet and oil return opening, oil outlet therein to be connected to hydraulic system by pipeline.The hydraulic oil to flow back from hydraulic system is wanted
Entered in fuel tank by oil return opening.Currently, the hydraulic oil to flow back from hydraulic system is all from oil return opening directly into fuel tank.From
The hydraulic oil of hydraulic system reflux will produce bubble when directly into fuel tank.With bladdery hydraulic oil by oil pump by again
It is secondary be pumped into hydraulic system after, will produce vibrating noise, cavitate, to influence to entire hydraulic system normal work.
Utility model content
Problem to be solved in the utility model is to provide a kind of buffer-type tank drainback lid.It is returned using this buffer-type fuel tank
Oil cap can eliminate vibrating noise, avoid cavitating, it is ensured that hydraulic system works normally.
The above problem to be solved in the utility model is realized by following technical scheme：
The buffer-type tank drainback lid of the utility model includes upper cover, has oil return opening on upper lid, its main feature is that the upper cover
For rectangle, it is connected with the supporting rod perpendicular with it below both ends, there is upper oil-containing groove between the supporting rod at upper cover both ends, on
In the opposite both sides of oil-containing groove：It is higher than another side on one side, and has upper oil leaking hole on the slot bottom on its neighbouring low side.Under upper oil-containing groove
There is lower oil-containing groove in face, and the shape of lower oil-containing groove is identical as upper oil-containing groove, in opposite both sides：It is less than another side, flash on one side
Under the low side of upper oil-containing groove, and there is lower oil leaking hole on the slot bottom on its neighbouring low side.
The upper oil-containing groove is identical with the shape of lower oil-containing groove and is cuboid, flash and low side be located at its two
End.
The slot bottom length of lower oil-containing groove is less than the slot bottom length of upper oil-containing groove, and useful on the low side slot bottom of lower oil-containing groove
In the scarce side for forming lower oil leaking hole.
There is venthole on upper lid.
As can be seen from the above scheme, due to upper cover be provided below one end be higher than the other end upper oil-containing groove, and
It is machined with oil leaking hole on the slot bottom on the neighbouring low side of upper oil-containing groove.One end is provided with again below upper oil-containing groove less than the other end
The shape of lower oil-containing groove, lower oil-containing groove is identical as upper oil-containing groove, and is machined with lower leakage on the slot bottom on the neighbouring low side of lower oil-containing groove
Oilhole.After the hydraulic oil of hydraulic system reflux pours fuel tank from oil return opening, fall first on upper oil-containing groove, and from upper oil-containing groove
It is high-end flow to low side, then from the leakage of the oil leaking hole of upper oil-containing groove low side lower oil-containing groove it is high-end on.It falls high-end in lower oil-containing groove
On hydraulic oil again from its it is high-end flow to its low side, finally, flowed into fuel tank by the oil leaking hole of lower oil-containing groove low side.Entire mistake
Journey has passed through two-stage buffering, substantially reduces the impact force of reflux hydraulic oil, eliminates vibrating noise, avoid cavitation erosion, it is ensured that
The normal work of hydraulic system.
Description of the drawings
Fig. 1 is the buffer-type tank drainback lid structural schematic diagram of the utility model；
Fig. 2 is the buffer-type tank drainback lid stereogram of the utility model.
Specific implementation mode
As depicted in figs. 1 and 2, the buffer-type tank drainback lid of the utility model includes upper cover 2, and the upper cover 2 is rectangular
Shape is machined with oil return opening 4 and venthole 3 thereon.The supporting rod 1 perpendicular with it is both provided with below 2 both ends of upper cover.Wherein
Supporting rod 1 altogether there are four, there are two 2 both ends of upper cover are equal, their upper end is separately fixed at below the quadrangle of upper cover 2.
Upper cover 2 is provided below oil-containing groove 6, the both ends of upper oil-containing groove 6 respectively with the supporting rod 1 below 2 both ends of upper cover
It links together.In the opposite both sides of upper oil-containing groove 6：It is higher than another side on one side, and is machined on the slot bottom on its neighbouring low side
Upper oil leaking hole 61.Upper oil-containing groove 6 is provided below lower oil-containing groove 5, the both ends of lower oil-containing groove 5 respectively with below 2 both ends of upper cover
Supporting rod 1 links together.The shape of lower oil-containing groove 5 is identical as upper oil-containing groove 6, in opposite both sides：It is less than another side on one side,
Its flash is located under the low side of upper oil-containing groove 6, and is machined with lower oil leaking hole on the slot bottom on its neighbouring low side.Lower oil-containing groove 5
Slot bottom length be less than the slot bottom length of upper oil-containing groove 6, and be machined on the low side slot bottom of lower oil-containing groove 5 and be used to form lower leakage
The scarce side 51 of oilhole.
Wherein, the upper oil-containing groove 6 is identical with the shape of lower oil-containing groove 5 and is cuboid, flash and low side difference
Positioned at its both ends.
After the hydraulic oil of hydraulic system reflux pours fuel tank from oil return opening 4, fall first on upper oil-containing groove 6, and from upper
The high-end of oil-containing groove 6 flows to low side, then from the leakage of the oil leaking hole 61 of 6 low side of upper oil-containing groove lower oil-containing groove 5 it is high-end on.It falls under
Hydraulic oil on oil-containing groove 5 is high-end again from its it is high-end flow to its low side, finally, the oil leaking hole for passing through 5 low side of lower oil-containing groove flows into
In fuel tank.Whole process has passed through two-stage buffering.
