Technical Field

The invention relates to an oil feeding pipeline, in particular to an ICV valve assembly.

Background

The ICV valve assembly is a necessary component for connecting an automobile oil tank and an oil pipe, and when a vehicle refuels, an oil gun adds oil into the oil tank through the oil pipe and the ICV valve assembly, so that the sealing property between the oil tank and the ICV valve assembly is particularly important. In the prior art, an internal injection oil pipe assembly is disclosed, and the publication number is as follows: CN 207190789U, application date is: 2017.08.21, comprising a connecting pipe sleeved at the bottom of the oil filling pipe, which has the disadvantages that: the leakage protection device needs to be additionally provided with the cover caps, is complex in structure, higher in cost and more in assembly, and increases leakage channels.

Disclosure of Invention

The invention aims to provide an ICV valve assembly which is simplified in structure and reduced in cost.

The purpose of the invention is realized as follows: the utility model provides a ICV valve assembly, establishes the connecting pipe in notes oil pipe bottom including the cover, the bottom of connecting pipe is connected with the apron that will connect the pipe passageway bottom to open or close through the upset, install seal ring on the apron, seal ring is used for forming and seals between connecting pipe bottom and the apron.

Compared with the prior art, the invention has the beneficial effects that: the invention omits a cover cap in structure, simplifies the structure, reduces the production and manufacturing cost, and the assembly of the sealing washer does not need the cover cap by installing the sealing washer on the cover plate, thereby simplifying the assembly, reducing a leakage channel and improving the sealing performance and the reliability of the sealing washer during the operation. The invention can be used in the fuel tank of the automobile.

As an improvement of the invention, the middle part of the periphery of the cover plate is provided with an annular groove, and the sealing washer is sleeved in the annular groove. The assembly mode of using the annular groove to match with the sealing washer is more convenient and more flexible.

As an improvement of the invention, the inner annular surface of the sealing washer is in interference fit with the inner annular surface of the annular groove. The interference fit ensures the tightness of the sealing washer during assembly.

As an improvement of the invention, the top surface and the bottom surface of the sealing gasket are provided with gaps with the top surface and the bottom surface in the annular groove, so that the sealing gasket can slide up and down along the annular groove. The sealing washer can be arranged in a vertically sliding manner, so that the assembly flexibility is improved, and the adjustment of the sealing performance is facilitated.

As an improvement of the invention, the outer ring of the sealing washer is turned upwards. The structure of turning over upwards has strengthened the leakproofness between seal ring and the connecting pipe when the apron is closed.

As an improvement of the invention, the outer ring of the sealing washer is folded upwards by an angle of 10-15 degrees. The limiting of the angle ensures the convenience of processing and simultaneously ensures the sealing performance.

As an improvement of the invention, a concave platform matched with the sealing gasket is processed at the bottom of the connecting pipe. The cover plate is more convenient to assemble when being covered.

In order to further reduce the cost, the sealing washer is made of FVMQ materials.

Detailed Description

An ICV valve assembly as shown in fig. 1-4 includes a connecting pipe 2 sleeved at the bottom of an oil filling pipe 1, a sealing ring is disposed between the connecting pipe 2 and the oil filling pipe 1, a cover plate 3 for opening or closing the bottom of a channel of the connecting pipe 2 by turning is connected to the bottom of the connecting pipe 2, the cover plate 3 is mounted on the connecting pipe 2 through a torsion spring 4 and a pin, a sealing washer 5 is mounted on the cover plate 3, the sealing washer 5 is used for sealing between the bottom of the connecting pipe 2 and the cover plate 3, an annular groove is disposed in the middle of the periphery of the cover plate 3, the sealing washer 5 is sleeved in the annular groove, an inner annular surface 5b of the sealing washer 5 is in interference fit with an inner annular surface of the annular groove, gaps 3a and 3b are left between the top surface and the bottom surface of the sealing washer 5 and the top and bottom surfaces in the annular groove, so that the sealing washer 5 can slide up and down along the annular groove, an outer ring of the sealing washer 5 turns upwards by 5a 5.

The integrated valve body structure reduces the cost, the installation of the sealing washer 5 does not need a cover cap, the structure is simplified, the assembly relation is changed, one assembly is omitted, the leakage probability is avoided, the assembly efficiency is improved, the material of the sealing washer 5 is changed from the original FKM to the FVMQ, and the cost is greatly reduced.

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