Description
Technical field
This utility model is related to hydraulic oil container technical field, more particularly to a kind of hydraulic fuel tank cap plate assembly structure.
Background technology
In engineering machinery vehicle, general hydraulic oil container is equipped with respiratory organ, and Main Function is the pressure for ensureing fuel tank internal
It is identical with external pressure, in case producing larger normal pressure or negative pressure, and play a role in filtering when air passes in and out fuel tank.
But the respiratory organ poor filtration effect of Current Domestic, structure is single, and bleed phenomenon often occurs in Jing.
At present, in engineering machinery and industrial vehicle, the fuel sucking pipe, respiratory organ and tank cover in general hydraulic system is
Separate, wasting space is so installed, is increased cost, and work efficiency is not high.Although also providing oil suction in prior art
Pipe, the integrated tank cover assembly apparatus of respiratory organ and tank cover, but often due to covering plate structure, screen material,
The reasons such as installation site, whole device structure are not sufficiently stable, and when the oil gas of fuel tank exhalation is cooled into fluid, fluid can seepage
To outside fuel tank, fuel door and tank surface look oil, it is impossible to solve the phenomenon that respiratory organ emits oil seepage very well.
Utility model content
In view of the foregoing, this utility model provides a kind of hydraulic fuel tank cap plate assembly structure, and simple structure saves empty
Between, make total link into an integrated entity, structure is more stable, and alleviation emits the phenomenon of oil seepage, improves work efficiency, reduces production
Cost.
For reaching above-mentioned purpose, this utility model solves the technical scheme adopted by its technical problem is：
A kind of hydraulic fuel tank cap plate assembly structure, including：Hydraulic oil tank cover board, the hydraulic oil tank cover board include at least four
Individual connecting hole；Fuel sucking pipe, the fuel sucking pipe main body are U-tube, including the second end of U-tube first end and U-tube, the U-tube
Length of the length of first end more than the second end of the U-tube；The U-tube first end is vertically fixed on through the connecting hole
In hydraulic oil tank cover board；The lower end of the U-tube first end is provided with external screw thread；Filter element, the filter element include filter element first end
With the second end of filter element；The filter element first end is provided with female thread, and the U-tube first end is connected with the filter element first end screw thread
Connect；Respiratory organ connecting tube, the respiratory organ connecting tube are vertically fixed in hydraulic oil tank cover board through the connecting hole；Bend pipe,
The bend pipe is vertically fixed in hydraulic oil tank cover board through the connecting hole；And oil return pipe, the oil return pipe is through the company
Connect hole to be vertically fixed in hydraulic oil tank cover board.
Its further feature is as follows：
The female thread of the U-tube first end is different directions with the external screw thread of the filter element first end.
Packing ring is provided with the connecting hole.
Due to the utilization of above-mentioned technical proposal, this utility model has following beneficial effect compared with prior art：The liquid
Force feed case lid plate assembly structure simple structure, saves space, makes total link into an integrated entity, and structure is more stable, alleviates
The phenomenon of oil seepage is emitted, work efficiency is improved, production cost is reduced.
