Connect dome face 314 and circular bottom surface 315 second stops cambered surface 316, is offered on the axial direction of passage closure part 31 more
Individual through hole 313, through hole 313 pass through dome face 314 and circular bottom surface 315, and when fluid storage device 60 tilts, second stops cambered surface
316 stop two passages.When fluid storage device 60 is horizontal, two passages 40 and the position pair of connecting rod 33
Should so that air-flow in fluid storage device 60 through two passages 40 flow through multiple through holes 313 and at balance pipe 62 with outside
Boundary's air communicates.
Reference picture 6, the end of free side pipeline section 11 and the end of installation side pipeline section 12 are respectively equipped with the inside to U-tube 10
Prominent the first chocking construction 141 and the second chocking construction 142, the first chocking construction 141 are used to prevent the first sealing-plug 20 from sliding
Go out and the second chocking construction 142 is used to prevent the second sealing-plug 30 from skidding off.Specifically, U-tube 10 mainly by body (including peace
Fill side pipe section 11, connecting portion 13 and free side pipeline section 12, installation side pipeline section 11 and free side pipeline section 12 by U-tube connecting portion 13
Connection), the first chocking construction 141, passage 40, the chocking construction 142 of flange 111 and second form, flange 111 is (alternatively referred to as
Rotational structure) it can mainly allow overall 360 degree of U-tube 10 to rotate；Flange 111 is mainly used for U-tube 10 being fixed to liquid
On the roof of body receptacle 60, other effects include meeting the rotations of 360 degree of U-tube and prevent liquid in fluid storage device 60 from
Flowed out in gap between the two, the simplest example of only apply, concrete application structure can be with more complicated.

Rake angle, L are the range of the second sealing-plug, and h is the distance between connecting portion of passage and U-tube, and f is segment seal
The height in portion.Because above-mentioned relation be present in the range L of the second sealing-plug 30 and the minimum cant α of fluid storage device,
By rational structure design, under the requirement for meeting above-mentioned relation formula, the different anti-tilting apparatus in angle of inclination are can be designed that.
That is, the minimum cant α of fluid storage device, which is basis, artificially it is expected a default angle, according to the default angle
Degree α calculates range L, and the size of all parts is then designed by above-mentioned equation, and then designs whole anti-leak dress
Put.
In the prior art, if sealing-plug is from outside sealing hole, just when tumbling, fluid can incite somebody to action from inside
Piston ejects, and causes to leak；If from inner sealing, due in motion, what sealing-plug always moved downward, to realize
Seal from the bottom up, structure can be more complicated.The indirect sealing means described in the utility model are selected, after sealing, if fluid
Want leakage occurs from passage, it is necessary to apply sealing-plug one radial load, only effectively reach makes sealing-plug to a certain degree
During large deformation, can just produce leakage, even if leaking, leakage rate also can very little, therefore reliability greatly improves；Therefore, with
Prior art is compared, device for preventing leakage of the present utility model, and it has adjustable angle (adjustment size is realized), while is not inclined
The limitation of falling direction, the balance pipe of the fluid storage device such as fuel tank, the larger spy of operating angle scope can be also closed in smaller angle
Point.
Preferred embodiment of the present utility model is these are only, is not limited to the utility model, for this area
Technical staff for, the utility model can have various modifications and variations.It is all within the spirit and principles of the utility model,
Any modification, equivalent substitution and improvements made etc., should be included within the scope of protection of the utility model.
