CN203230980U - Ring-shaped connector - Google Patents

Abstract

The utility model discloses a ring-shaped connector, which comprises a ring-shaped fixed end (1) and a pipeline connecting end (2), wherein the ring-shaped fixed end (1) and the pipeline connecting end (2) are connected into a whole; the pipeline connecting end (2) is provided with external threads (2.1) which are detachably connected with a clamp sleeve on a pipeline; a port inside the pipeline connecting end (2) is provided with a conical surface (2.2) used for being sealed with the pipeline; a big-sized end of the conical surface (2.2) is positioned at the port of the pipeline connecting end (2); and a small-sized end is positioned in the pipeline connecting end (2). After the structure is adopted, when the ring-shaped connector is maintained or detected, a whole pipe and the ring-shaped connector need not to be dismantled completely, so that on one hand, the time and labor can be saved, and on the other hand, the cost is lowered; and in addition, a conical surface sealing structure is adopted for the pipe and the pipeline connecting end, an end face seal ring is not needed, and meanwhile, the sealing performance of conical surface sealing is better, so that the cost can be saved, and the sealing performance of a connecting part is also improved.

Description

Ring joint

Technical field

The utility model relates to the auto parts machinery technical field, specifically is a kind of for the ring joint on the motor car engine.

Background technique

Component are numerous in the motor car engine, and wherein ring joint is wherein a kind of.The ring joint of prior art, an end are annular fixed end, and the cutting ferrule on the other end and the pipe is stuck or rivet, and pipe and ring joint are non-disconnectable.Therefore, there is following shortcoming in the ring joint of this structure:

1) because pipe and ring joint are non-disconnectable, therefore, when keeping in repair or detect, whole pipe and ring joint all will be pulled down, be wasted time and energy on the one hand, also increase cost on the other hand;

2) in addition, the sealing configuration between common tube and the ring joint is the structure of end face seal, and therefore, the time one is long, its poor sealing performance.

The model utility content

Technical problem to be solved in the utility model is, the removable connection of cutting ferrule on a kind of and the pipe is provided, thus time saving and energy saving, the ring joint that can reduce cost of convenient for maintaining or detection.

For solving the problems of the technologies described above, the ring joint that the utility model provides comprises the annular fixed end and the pipeline connecting end that are connected as a single entity, described pipeline connecting end have for pipeline on the removable outside thread that is connected of cutting ferrule.

Port in the described pipeline connecting end have for the conical surface of line seal, the large scale end of the conical surface is positioned at the port of pipeline connecting end, the small size end is positioned at the pipeline connecting end.

Angle between the axis of the bus of the described conical surface and line seal end is 12 °.

After adopting above structure, the utility model compared with prior art has the following advantages:

1) owing to is connected by removable being threaded between pipeline connecting end and the cutting ferrule, therefore, be removable between ring joint and the pipe, like this, when keeping in repair or detect, need not whole pipe and ring joint are all pulled down, time saving and energy saving on the one hand, also reduce cost on the other hand;

2) in addition, pipe and pipeline connecting end adopt the structure of conical surface seal, need not end-face seal ring, and the sealability of conical surface seal is better simultaneously, therefore, can save cost, improves the sealability of joint again.

Description of drawings

Fig. 1 is the structural representation of the utility model ring joint.

Fig. 2 is the plan structure schematic representation of Fig. 1.

Wherein: 1, annular fixed end; 2, pipeline connecting end; 2.1, outside thread; 2.2, the conical surface; Angle between the axis of the bus of α, the conical surface and line seal end.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

By the structural representation of the utility model ring joint illustrated in figures 1 and 2 as can be known, it comprises annular fixed end 1 and the pipeline connecting end 2 that is connected as a single entity, described pipeline connecting end 2 have for pipeline on the removable outside thread that is connected 2.1 of cutting ferrule.

Ports in the described pipeline connecting end 2 have for the conical surface 2.2 of line seal, the large scale end of the conical surface 2.2 is positioned at the port of pipeline connecting end 2, the small size end is positioned at pipeline connecting end 2.

In the present embodiment, the angle α between the axis of the bus of the described conical surface 2.2 and line seal end 2 is 12 °.

Claims (3)

1. ring joint comprises the annular fixed end (1) and the pipeline connecting end (2) that are connected as a single entity, it is characterized in that: described pipeline connecting end (2) have for pipeline on the removable outside thread that is connected of cutting ferrule (2.1).

2. ring joint according to claim 1, it is characterized in that: the port in the described pipeline connecting end (2) have for the conical surface (2.2) of line seal, the large scale end of the conical surface (2.2) is positioned at the port of pipeline connecting end (2), and the small size end is positioned at pipeline connecting end (2).

3. ring joint according to claim 2 is characterized in that: the angle (α) between the axis of the bus of the described conical surface (2.2) and line seal end (2) is 12 °.
