Description

Quick-release type pipeline connecting device with compensation function

Technical Field

The utility model belongs to the technical field of the pipe connection, especially, relate to a quick-release type pipe connection device with compensation function.

Background

The pipe is an important component for transporting gas, and the connection of the pipe is an indispensable component thereof. The existing pipeline connection standard part is mostly suitable for a pipeline with a circular section and cannot be used for connecting pipelines with non-circular sections. Because there is machining error in pipeline or airborne equipment, if adopt current pipeline connection standard component, then need set up dedicated pipeline compensation arrangement, not only increased weight, and be not suitable for the pipeline that installation space is narrow and small on the machine.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: a quick release type pipe connection device with a compensation function is provided for overcoming or at least reducing the problem that the existing connection device can not be used for connecting non-circular section pipes.

The technical scheme of the utility model:

the utility model provides a quick-release type pipe connection device with compensation function, includes first connection clamp, the clamp is connected to the second, the clamp is connected to the third, the clamp is connected to the fourth, first sealed rubber ring, the sealed rubber ring of second, first connection clamp, the clamp is connected to the second, the clamp is connected to the third, the clamp is connected to the fourth in proper order end to end, first connection clamp, the clamp is connected to the second, the clamp is connected to the third, the clamp inboard is connected to the fourth is provided with the U-shaped groove that the size is the same, the U-shaped groove make up into an annular groove, first sealed rubber ring, the sealed rubber ring setting of second be in the annular groove, the annular groove completely sealed.

The first connection clamp, the second connection clamp, the third connection clamp, fourth connection clamp both ends all are provided with the installation auricle, four connection clamps pass through bolted connection.

The cross section of the first sealing rubber ring and the cross section of the second sealing rubber ring are M-shaped.

The outer surfaces of the first sealing rubber ring and the second sealing rubber ring are attached to the inner wall surface of the annular groove.

The outer wall thickness of the first sealing rubber ring and the outer wall thickness of the second sealing rubber ring are the same as the wall thickness of the middle part.

The first connection clamp, the second connection clamp, the third connection clamp and the fourth connection clamp are provided with a gap between every two adjacent lug plates at two ends.

The utility model has the advantages that: the utility model provides a quick-release type pipe connection device with compensation function, easily installation has the compensation ability, has the leakproofness, is applicable to abnormal shape pipeline. The connection of abnormal shape pipeline in the narrow and small space can be realized to can compensate the machining error of pipeline and airborne equipment.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a cross-sectional view of the present invention;

FIG. 3 is a schematic structural view of a first sealing rubber ring and a second sealing rubber ring;

the connecting structure comprises a first connecting hoop 1, a second connecting hoop 2, a third connecting hoop 3, a fourth connecting hoop 4, a first sealing device 5, a second sealing device 6 and a bolt 7.

Detailed Description

The utility model is further described with reference to the accompanying drawings, and the quick-release pipe connecting device with compensation function of the utility model comprises a first connecting clamp 1, a second connecting clamp 2, a third connecting clamp 3, a fourth connecting clamp 4, a first sealing rubber ring 5 and a second sealing rubber ring 6, wherein the first connecting clamp 1, the second connecting clamp 2, the third connecting clamp 3 and the fourth connecting clamp 4 are sequentially connected end to end, U-shaped grooves with the same size are arranged inside the first connecting clamp 1, the second connecting clamp 2, the third connecting clamp 3 and the fourth connecting clamp 4, the U-shaped grooves are combined into a ring groove, the first sealing rubber ring 5 and the second sealing rubber ring 6 are arranged in the ring groove to completely seal the ring groove, the subsection position of the sealing device can not be positioned at the connection part of each connecting clamp, ensuring a segment position misalignment with the connector clip.

The U-shaped groove on each connection clamp realizes the installation compensation of the machining tolerance of the pipeline, and the four connection clamps are convenient for the installation of the special-shaped pipeline connection device in the narrow space.

First connection clamp 1, second connection clamp 2, third connection clamp 3, fourth connection clamp 4 both ends all are provided with the installation auricle, four connection clamps pass through bolt 7 and connect.

The cross section of each of the first sealing rubber ring 5 and the second sealing rubber ring 6 is M-shaped, the outer wall thickness of each of the first sealing rubber ring 5 and the second sealing rubber ring 6 is the same as the wall thickness of the middle part of each of the first sealing rubber ring 5 and the second sealing rubber ring 6, so that the compensation capacity of the connecting device is guaranteed, and the sealing performance of the connecting device is guaranteed;

first connection clamp 1, second connection clamp 2, third connection clamp 3, there is a clearance between the two liang of adjacent auricles in fourth connection clamp 4 both ends, first rubber seal 5 both can both be given in this clearance, the installation headspace of second rubber seal 6 has guaranteed the installation pretightning force of connecting the clamp simultaneously, and then has guaranteed connecting device's leakproofness.
