Abstract

The utility model provides a quick assembly disassembly's pipeline, all be equipped with flange, the inboard two outer tubes of establishing the sealing washer including the tip outside, its characterized in that is at the interior wall connection inner tube section of one of them outer tube end portion, and the one end of this inner tube section is plain end, the other end is the flaring end, and the flaring end is fixed on the inner wall of outer tube end portion. Can conveniently with the flaring end lug weld of interior pipeline section at the inner wall of outer tube end portion, improve pipeline dismouting efficiency greatly, especially the arc horn mouth to turning up of interior pipeline section flaring end can conveniently weld with the inside pipe wall of outer tube end portion, can not only effectively reduce the processing degree of difficulty, and this welding point is in outer tube end portion and flange joint's inner wall position moreover, can shelter from the welding vestige with the help of the flange, improves the surface smoothness of outer tube wall, realizes tearing open fast and adorning of pipeline.

Description

Pipeline capable of being quickly disassembled and assembled

Technical Field

The utility model relates to a quick assembly disassembly's pipeline belongs to pipeline design and manufacturing technical field.

Background

In cigarette production, the air pipe can be quickly disassembled when tobacco is cut into shreds, the tobacco is smoked, and the air pipe is ventilated and dedusted. In order to ensure the sealing performance, the quick-release air pipe is provided with an inner pipe at the joint and a sealing ring between the inner pipe and the outer pipe. The existing inner pipe is connected with the outer pipe in a welding mode, and the welding position needs to adopt a cambered surface structure, so that the existing technology can only be processed and manufactured through a die, the processing difficulty of the air pipe is increased, the working efficiency of the air pipe during replacement and maintenance is reduced, and the maintenance cost is increased. In addition, since the welding point is far from the joint of the end portions of the outer tube, the trace of welding can be seen from the outer surface. There is therefore a need for improvements in the prior art.

Disclosure of Invention

Because the structure reason, the inner tube that leads to the preparation technology complicated for solving current quick detach tuber pipe junction, influences the problem of maintenance efficiency and cost, the utility model provides a quick assembly disassembly's pipeline.

The utility model discloses a following technical scheme accomplishes: the utility model provides a quick assembly disassembly's pipeline, includes that the tip outside all is equipped with flange, the inboard two outer tubes of establishing the sealing washer, and the pipe section in the interior wall connection of one of them outer tube end portion, the one end of this interior pipe section is plain end, the other end is the flaring end, and the flaring end is fixed on the inner wall of outer tube end portion to the convenience welds the flaring end of interior pipe section and the inner wall of outer tube end portion, and the greatly reduced processing degree of difficulty improves pipeline dismouting efficiency.

The inner diameter and the outer diameter of the flaring end of the inner pipe section are larger than those of the inner diameter and the outer diameter of the inner pipe section, and the flaring end of the flaring end is designed into an outwards-turned-out arc-shaped bell mouth so as to facilitate the welding of the inwards-turned-out arc-shaped bell mouth of the inner pipe and the inner wall of the outer pipe end, thereby reducing the processing difficulty.

The connection part of the arc-shaped bell mouth with the inward turning-out inner pipe section and the outer pipe is positioned on the inner wall of the connection part of the end part of the outer pipe and the flange, so that welding marks are shielded by the flange, and the surface smoothness of the outer pipe wall is improved.

The utility model has the advantages of it is following and effect: adopt above-mentioned scheme, can conveniently with the flaring end direct welding of interior pipeline section at the inner wall of outer tube end portion, improve pipeline dismouting efficiency greatly, especially the arc horn mouth to turning up of interior pipeline section flaring end can conveniently weld with the inside pipe wall of outer tube end portion, can not only effectively reduce the processing degree of difficulty, and this welding point is in outer tube end portion and flange joint's inner wall position, can shelter from the welding vestige with the help of the flange, improve the surface smoothness degree of outer tube wall, realize tearing open fast and the dress of pipeline.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The utility model provides a pipeline capable of being quickly disassembled and assembled, which comprises a left outer pipe 1 and a right outer pipe 1, wherein the outer sides of the end parts are respectively provided with a connecting flange 2, the inner sides of the left outer pipe 1 and the right outer pipe 1 are provided with a sealing ring 4, the inner wall of the end part of the outer pipe on the right side is connected with an inner pipe section 3, the left end of the inner pipe section 3 is a flat end, the right end of the inner pipe section 3 is a flaring end 31, and the flaring end 31 is fixed on the inner wall of the end part of the outer pipe 1; the inner diameter and the outer diameter of the flared end 31 of the inner pipe section 3 are both larger than those of the inner diameter and the outer diameter of the inner pipe section 3, and the flared end of the flared end 31 is an arc-shaped bell mouth turning outwards, so that the arc-shaped bell mouth turning outwards of the inner pipe section 3 can be conveniently welded with the inner wall of the end part of the outer pipe 1, and the processing difficulty is further reduced; the connection part of the outwards turned arc-shaped bell mouth of the inner pipe section 3 and the outer pipe 1 is positioned on the inner wall position of the end part of the outer pipe 1 connected with the connecting flange 2, so that welding marks are shielded by the connecting flange 2, and the surface smoothness of the wall of the outer pipe 1 is improved.

Claims

1.
