Description

Novel fuel tank control valve

Technical Field

The utility model relates to a fuel tank, in particular to fuel tank control valve.

Background

A tank control valve (FLVV valve) is installed on top of a tank assembly, and a fuel tank control valve is disclosed in the prior art, and its publication number is: CN209909175U, its shortcoming is that its sealed pad is through the installation shaping that integrated into one piece's mode was accomplished with sealed lid, and this technological method cost is higher, and to the precision requirement of each structural position processing of sealed lid and sealed pad in earlier stage higher, production efficiency is lower.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel fuel tank control valve solves the sealed lid of prior art and fills up integrated into one piece with high costs with sealed, problem that production efficiency is low.

The purpose of the utility model is realized like this: the utility model provides a novel fuel tank control valve, is including setting up the float in the valve body, and the exhaust hole has been seted up at the valve body top, and the feed liquor hole has been seted up to the valve body lateral part, sealed lid is installed to the float top surface, the lateral part of sealed lid is provided with a pair of otic placode, be provided with on the float with otic placode complex hook plate, hook plate slidable sets up in the otic placode, and the hook plate can pull sealed lid downstream when last spacing, sealed covering install with exhaust hole complex sealed the pad, the air vent has been seted up at sealed pad center, the mounting hole has been seted up at the center of sealed lid, the bottom periphery of sealed pad is processed into the conical surface, sealed pad inserts the mounting hole sets up.

Compared with the prior art, the beneficial effects of the utility model reside in that, the utility model discloses a to seal the processing of pad bottom periphery and become the cone structure for it only needs to insert when assembling with sealed lid and can accomplish the assembly, and the assembly is more high-efficient, and greatly reduced to sealed lid, the requirement of sealed pad machining precision, thereby the cost is reduced, further improved production efficiency. The utility model discloses can be used to in the car fuel tank.

In order to enhance the reliability and the sealing performance of the assembled sealing gasket, the lower edge of the mounting hole is provided with a circumferential concave table, and the lower part of the sealing gasket is provided with a circumferential boss matched with the circumferential concave table.

In order to further simplify the structure, the top of the floater is provided with a round table used for blocking the vent hole from the bottom.

In order to make the up-and-down movement of the sealing cover in the valve body more stable, a plurality of guide rods are formed by extending the bottom of the top surface of the valve body downwards.

Drawings

Fig. 1 is a schematic view of the three-dimensional structure of the present invention.

Fig. 2 is a sectional view of the internal structure of the present invention.

Fig. 3 is an enlarged view of a portion a in fig. 2.

The air-tight valve comprises a valve body 1, an exhaust hole 1a, a liquid inlet hole 1b, a floater 2, a circular truncated cone 2a, a sealing cover 3, a mounting hole 3a, an annular concave table 3b, an ear plate 4, a hook plate 5, a sealing gasket 6, an air vent 6a, an annular convex table 6b, a conical surface 6c and a guide rod 7.

Detailed Description

As shown in fig. 1-3, a novel fuel tank control valve comprises a float 2 arranged in a valve body 1, an exhaust hole 1a is arranged at the top of the valve body 1, a liquid inlet hole 1b is arranged at the side of the valve body 1, a sealing cover 3 is arranged on the top surface of the float 2, a pair of ear plates 4 is arranged at the side of the sealing cover 3, a hook plate 5 matched with the ear plates 4 is arranged on the float 2, the hook plate 5 is slidably arranged in the ear plates 4, the sealing cover 3 can be pulled to move downwards by the hook plate 5 when the sealing cover is limited upwards, a sealing gasket 6 matched with the exhaust hole 1a is arranged on the sealing cover 3, an air vent 6a is arranged at the center of the sealing gasket 6, a mounting hole 3a is arranged at the center of the sealing cover 3, a conical surface 6c is processed at the periphery of the bottom of the sealing gasket 6, the sealing gasket 6 is inserted into the mounting hole 3a, a circumferential concave platform 3b is processed at the lower edge of the mounting hole 3a, a circumferential convex platform 6b matched with the circumferential concave platform 3b is processed at the lower part of the sealing gasket 6, the top of the floater 2 is provided with a round platform 2a for plugging the vent hole 6a from the bottom, and the bottom of the top surface of the valve body 1 extends downwards to form a plurality of guide rods 7.

The utility model discloses the during operation, float 2 rises under buoyancy, and it rises to drive sealed lid 3 and sealed 6 of filling up, and sealed 6 of filling up will exhaust hole 1a and seal, and the bottom of sealed 6 of filling up seals under the effect of round platform 2a simultaneously seals, and when buoyancy is not enough to support float 2, float 2 descends under the action of gravity, and round platform 2a breaks away from sealed 6 at first, and sealed lid 3 of 4 pulling of 5 cooperation otic placodes of rethread hook plate, the upper portion of driving sealed 6 of filling up breaks away from exhaust hole 1a, the utility model discloses a with sealed 6 bottom periphery processing cone structures of filling up for it only needs to insert when assembling with sealed lid 3 and can accomplish the assembly, and the assembly is more high-efficient, and greatly reduced sealed 3, the requirement of 6 machining precision of filling up, thereby the cost is reduced, further improved production efficiency.

The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
