Embodiment 1

[0045] like Figure 2-3 As shown, the pipeline 1 is provided with a trumpet head 4, and the plug 3 is provided with a frustum-shaped blocking block 31, and the small circle diameter of the blocking block 31 is smaller than the diameter of the trumpet head, and the blocking block The diameter of the great circle of 31 is greater than the diameter of the horn head;

[0046] The blocking block 31 is closely attached to the inner side of the horn head through the cooperation of the fastening bolt and the plug, so that the blocking block intersects with the inside of the pipeline to achieve a sealing effect.

[0047] The horn head is divided into an inner layer 42 and an outer layer 41, the outer layer 41 is closely attached to the inner layer 42, and the blocking block is closely attached to the plug through the cooperation of the fastening bolt and the plug. on the inner layer. Due to the tightening effect of the fastening bolts, the single-layer horn head is easy to wear and c...

Embodiment 2

[0049] like Figure 4-5 As shown, the end is divided into an inner layer and an outer layer, and an angle is formed between the outer layer and the inner layer, so that the inner layer is elastic when it fits the block, making the fit more tightly and the sealing effect better .

[0050] A frustum-shaped blocking block is arranged inside the plug, the diameter of the small circle of the truss is smaller than the diameter of the horn head, and the diameter of the large circle of the truss is larger than the diameter of the horn head, so that the block is in contact with the pipeline. There is a cross inside to play a sealing effect.

[0051] The blocking block is closely attached to the end point of the inner layer through the cooperation of the fastening bolt and the plug to form a seal to prevent oil leakage. Under the premise of the same strength, the line seal is stronger than the surface seal, and the sealing effect is better.

Embodiment 3

[0053] like Figure 6-7 As shown, the end is divided into an inner layer and an outer layer, and an angle is formed between the outer layer and the inner layer; resulting in the inner layer having the function of a shrapnel, which can be used when the online seal or the surface seal is not tightly sealed. to a certain compensation

[0054] A frustum-shaped blocking block is arranged inside the plug, the diameter of the small circle of the truss is smaller than the diameter of the horn head, and the diameter of the large circle of the truss is larger than the diameter of the horn head;

[0055] The side of the blocking block is provided with several platform-shaped clamping positions for clamping the inner layer.

[0056] The purpose of setting the platform-shaped locking position is mainly to slow down the friction between the inner layer and the blocking block, and prolong the service life of the sealable device. When in use, the horn head can be placed at the corresponding...

Abstract

The invention provides an oil path sealing device and a processing method thereof and relates to a car part, in particular to an oil path sealing device and a processing method thereof. The oil path sealing device is good in sealing effect and long in service life. The oil path sealing device comprises a pipeline, a fastening bolt and a plug, wherein the fastening bolt is arranged on the pipeline in a sleeving manner; a through hole is formed in the middle of the plug, and a thread matched with the fastening bolt is formed on the inner side of the plug. According to the oil path sealing device and the processing method thereof provided by the invention, the plug is adopted for plugging the pipeline; a circular truncated cone-shaped plugging block is arranged in the plug, so that line sealing or surface sealing is formed between the pipeline and the plug; meanwhile, the fastening bolt is utilized for enhancing a sealing effect. A horn mouth adopts a double-layer design, so that the wear resistance of the horn mouth is further enhanced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a vehicle component, in particular to an oil passage sealing device and a processing method thereof. Background technique [0002] With the development of society, the application of automobiles is becoming more and more extensive. Therefore, the safety of automobiles is particularly important. The oil circuit between the automobile fuel tank and the engine needs to be connected by pipes and sealing devices. The existing sealing devices use bolts and rubber seals. The rubber sealing ring cooperates to achieve the purpose of preventing oil leakage, but the chemical properties of the rubber sealing ring will gradually change with the increase of use time, resulting in the sealing ring becoming hard and brittle, losing the sealing effect, and affecting the service life of the entire sealing device. Moreover, the thread of the bolt during the installation process will cause damage and fracture of the sealing ring, which will affect...
