Abstract
The utility model discloses a venturi type oil filling device. The venturi type oil filling device comprises a valve and a pipe plug-in which is arranged on the valve; the inner side of the end which is towards the outside of the valve is provided with a wide hole when the pipe plug-in is arranged on the valve; the inner side of the other end which is towards the inside of the valve is provided with a narrow hole when the pipe plug-in is arranged on the valve; the wide hole is communicated with the narrow hole. According to the venturi type oil filling device, the pipe plug-in and the valve are arranged according to the venturi type principle, the oil can be filled automatically after the venturi type oil filling device is placed into an oil tank, and the size of the pipe plug-in can be replaced according to different flow rates; the structure of the venturi type oil filling device is reasonable and compact, no additional system power consumption is required, and the ideal effect can be achieved; the structure is simple and quite practical.
Description
Technical field
The utility model relates to mechanical-hydraulic field, is a kind of venturi type recharging oil device specifically.
Background technique
Venturi type, also claims venturi effect.This phenomenon is with its finder, and Italian physicist's venturi (Giovanni Battista Venturi) is named.This effect refers near swiftly flowing gas can produce low pressure, thereby produces suction-operated.Utilize this effect can produce Venturi tube.
When gas or liquid flow in Venturi tube the inside, the narrowest place at pipeline, dynamic pressure (velocity head) reaches maximum value, and static pressure (Resting Pressure) reaches minimum value, and the speed of gas (liquid) rises because of the relation of the cross-section variation of shoving.Whole shoving all will can be experienced at one time pipeline and dwindled process, thereby pressure also reduces at one time.And then generation pressure difference, this pressure difference is for measuring or providing an external suction to fluid.
At present, hydraulic closed system adopts auxiliary pump recharging oil device to loop repairing substantially, and apparatus takes up space larger, and extra consumption systems power, exists heating severe, safeguards inconvenient problem.
Therefore, need especially a kind of venturi type recharging oil device, to solve problems of the prior art.
Model utility content
The purpose of this utility model is in order to solve in prior art, adopt auxiliary recharging oil device to loop repairing, apparatus takes up space larger, needs the defect of extra consumed power, provides a kind of venturi type recharging oil device to solve problems of the prior art.
For achieving the above object, the technical solution of the utility model is as follows:
A venturi type recharging oil device, comprises valve body and is arranged on the conduit insert on valve body; When described conduit insert is arranged on valve body, towards that inner side, one end of valve body outside, gross porosity is set, when described conduit insert is arranged on valve body, towards the other end inner side of valve inner, pore, described gross porosity spongy is set.
In the utility model, described conduit insert comprises outside thread, and described conduit insert is communicated with valve body by outside thread.
In the utility model, described valve body be shaped as cuboid, described conduit insert be shaped as cylindrical body.
In the utility model, the side of described valve body pipe laying plug-in unit is square.
In the utility model, the diameter of described conduit insert is less than the minimum length of the arbitrary limit of cuboid valve body face.
beneficial effect
A kind of venturi type recharging oil device of the present utility model, compared with prior art, utilizes venturi type principle design to become conduit insert and valve body two-part, puts into after fuel tank, and repairing automatically, conduit insert can be changed size according to different flow; Make the rational in infrastructure, small and exquisite of equipment, without extra consumption systems power, reach ideal effect; Simple in structure, very practical, realize the purpose of this utility model.

Wherein: 1, valve body; 2, conduit insert; 21, outside thread; 3, gross porosity; 4, pore.
Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is further described.
Embodiment
As shown in Fig. 1 ~ 5, Fig. 1 is structural representation of the present utility model; Fig. 2 is the left view of Fig. 1; Fig. 3 is the right elevation of Fig. 1; Fig. 4 is the structural representation of the utility model conduit insert; Fig. 5 is the sectional view of the utility model conduit insert.
A venturi type recharging oil device, comprise valve body 1 and be arranged on valve body 1 can according to different flow change size conduit insert 2; When conduit insert 2 is arranged on valve body 1, towards that inner side, one end of valve body 1 outside, gross porosity 3 is set, when conduit insert 2 is arranged on valve body 1, towards the other end inner side of valve body 1 inside, pore 4, gross porosity 3 spongy 4 is set; By venturi type principle design, become conduit insert 2 and valve body 1 two-part, put into after fuel tank, repairing automatically, conduit insert 2 can be changed size according to different flow.
The side of valve body 1 pipe laying plug-in unit 2 is square, reaches good using effect.
The diameter of conduit insert 2 is less than the minimum length of the arbitrary limit of cuboid valve body 1 face; Make this practical product reach small and exquisite, effect rational in infrastructure.
A kind of venturi type recharging oil device of the present utility model, compared with prior art, utilizes venturi type principle design to become conduit insert 2 and valve body 1 two-part, puts into after fuel tank, and repairing automatically, conduit insert 2 can be changed size according to different flow; Make the rational in infrastructure, small and exquisite of equipment, without extra consumption systems power, reach ideal effect; Simple in structure, very practical, realize the purpose of this utility model.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiments, and General Principle described herein is applied in other embodiments and needn't passes through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art are according to announcement of the present utility model, and not departing from the improvement that the utility model category makes and revise all should be within protection domain of the present utility model.
