Description
Technical Field
The utility model relates to an oil feeding pipeline, in particular to 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.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a ICV valve assembly simplifies the structure, reduce cost.
The purpose of the utility model is realized like this: 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 beneficial effects of the utility model reside in that: the utility model discloses structural cap of having saved has simplified the structure, has reduced production manufacturing cost, and through installing seal ring on the apron, seal ring's assembly no longer needs the block, has simplified the assembly, has reduced leak path one, improves the leakproofness and the reliability of its during operation. The utility model discloses can be used to in the car fuel tank.
As an improvement of the utility model, the periphery middle part of apron is equipped with the annular groove, seal ring cover is established 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 the improvement of the utility model, the inner ring surface of the sealing washer is in interference fit with the inner ring surface of the annular groove. The interference fit ensures the tightness of the sealing washer during assembly.
As the improvement of the utility model, the top surface and the bottom surface of the sealing washer leave clearances with the top surface and the bottom surface in the ring groove, so that the sealing washer can slide up and down along the ring 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 utility model, the outer ring of the sealing washer turns 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 utility model, the outer ring of the sealing washer turns 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 utility model, the bottom of the connecting pipe is provided with a concave platform matched with the sealing washer. 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.
