The top of described locking lower house 12 is provided with container cavity, and the low profile of described container cavity and locking upper shell 2 matches, and described locking upper shell 2 bottom is placed in the container cavity on locking lower house 12 top.
The outer edge of described valve body 6 upper end is provided with pore 15, and described valve body 6 top peripheral is arranged with exterior seal ring 5.
Be arranged with a circle hold down groove outside described outside housing cover 1, be arranged with set collar 4 in described hold down groove, described outside housing cover 1 is connected as one by set collar 4 and valve body 6.
The middle part of described malleation valve block 10, negative pressure valve block 7 is all in bowl body shape, and the upper end of described malleation valve block 10, negative pressure valve block 7 is equipped with flange.
The utility model compared with the existing technology, novel structure, simple, reasonable in design, not only there is basic locking function, and whether can to exceed according to tank internal pressure or lower than preset range, be exhausted or air-breathing, to maintain the moderate of tank pressure, thus prevent fuel tank from occurring because of the phenomenon of too high or too low the caused fuel tank deformed damaged of internal pressure; In addition, this vehicle oil filler tightening cover has good sealing function, can prevent oil gas from discharging, ensure that fluid can not be revealed, and this tightening cover only need rotate and once can reach sealing state, avoid the maloperation risk that complex operations flow process is brought, also prevent vehicle body lacquer painting to scratch simultaneously.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
In figure: 1, outside housing cover 2, locking upper shell 3, locking 4, set collar 5, exterior seal ring 6, valve body 7, negative pressure valve block 8, negative pressure spring 9, inner seal ring 10, malleation valve block 11, positive pressing spring 12, locking lower house 13, case spring 14, through hole 15, pore.
[detailed description of the invention]
Below in conjunction with accompanying drawing, following further illustrating is done to the utility model:
As shown in drawings, the utility model comprises: outside housing cover 1, locking upper shell 2, locking 3, case spring 13, locking lower house 12 and valve body 6, outside housing cover 1 covers on valve body 6, locking upper shell 2 and locking lower house 12 is provided with from top to bottom successively in outside housing cover 1, locking 3, case spring 13 is arranged in locking upper shell 2, positive pressing spring 11 is provided with from top to bottom successively in valve body 6, malleation valve block 10, negative pressure valve block 7 and negative pressure spring 8, positive pressing spring 11 upper end connects locking lower house 12, positive pressing spring 11 lower end connects malleation valve block 10, through hole 14 is provided with bottom malleation valve block 10, negative pressure spring 8 upper end connects negative pressure valve block 7, negative pressure spring 8 lower end is connected on valve body 6, inner seal ring 9 is provided with between malleation valve block 10 and negative pressure valve block 7, negative pressure valve block 7 is by being tightly connected between inner seal ring 9 and valve body 6.
In the utility model, the top of locking lower house 12 is provided with container cavity, and the low profile of this container cavity and locking upper shell 2 matches, and the bottom of locking upper shell 2 can directly be placed in the container cavity on locking lower house 12 top, thus installation location is very convenient; The outer edge of valve body 6 upper end is provided with pore 15, and described valve body 6 top peripheral is arranged with exterior seal ring 5, when tank internal pressure whether exceed or lower than preset range time, be exhausted or air-breathing by this pore 15; Be arranged with a circle hold down groove outside outside housing cover 1, be arranged with set collar 4 in hold down groove, outside housing cover 1 is connected as one by set collar 4 and valve body 6; The middle part of malleation valve block 10, negative pressure valve block 7 is all in bowl body shape, the upper end of malleation valve block 10, negative pressure valve block 7 is equipped with flange, bowl body shape outer shape in the middle part of malleation valve block and the bowl body shape interior shape in the middle part of negative pressure valve block match, leave space between bowl body shape bottom surface in the middle part of malleation valve block and the bowl body shape bottom surface in the middle part of negative pressure valve block, inner seal ring is arranged between the flange of malleation valve block and negative pressure valve block.
When tank internal pressure exceedes preset range, fuel lid is exhausted, and its principle of work is: positive pressing spring pressurized, negative pressure spring tension, malleation valve block, inner seal ring and negative pressure valve block move, and in case, air is derived via the sealing surface of valve body and inner seal ring.When tank internal pressure is lower than preset range, fuel lid carries out air-breathing, and its principle of work is: negative pressure spring pressurized, and negative pressure valve block moves down, and extraneous air is imported by the through hole of malleation valve block.
The utility model adopts brand-new design plan, only needs to rotate once then can reach sealing state, simplifies the maloperation risk brought in complex operations flow process; Valve volume is little, can be designed with locating dowel pin, and when fuel lid opens oiling, fuel lid can directly be inserted in interior of body reserved opening, can prevent vehicle body lacquer painting from scratching; Tightening cover has sealing function, can prevent oil gas from discharging, if fuel tank is inverted, under certain internal pressure, fluid is not also revealed; Under the Packed prerequisite of tool, still also have respiratory function, when tank internal pressure exceedes preset value, can be exhausted or air-breathing, thus prevent fuel tank because internal pressure causes fuel tank deformed damaged.
The utility model is not by the restriction of above-mentioned embodiment; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
