Abstract
The invention relates to a pipeline extension device. The conventional metal pipeline extension device is generally made into a corrugated pipe by adopting stainless steel; when the pipeline is expanded, an impact force is generated for the stainless steel corrugated pipe; when the strength reaches the fatigue strength, the pipeline is broken; and if a torque force exists, the welded port of the pipeline easily cracks and cannot be repaired. The pipeline extension device comprises a sleeve (1) connected with a working pipeline (2), the sleeve is provided with a flange (3), a packing (4) is wound between the working pipeline of the other side and the sleeve, a gland (6) is welded on a connecting pipe (5) sleeved on the working pipeline of the other side, and the gland is connected with the flange through a nipple (7). The pipeline extension device is used for extension treatment and absorption of various liquid and gas delivery pipelines.
Description
Technical field:
The present invention relates to a kind of pipeline extension device.
Background technique:
Pipeline extension device is during pipeline connects because the link that the dimensional changes that causes of expanding with heat and contract with cold is recompensed.What pipeline extension device was the most frequently used has two kinds, and a kind of is the rubber tubing expansion bend, and another kind is the metallic conduit expansion bend.The bearing temperature of rubber tubing expansion bend is lower, it is less to bear pressure, the main feature of metallic conduit expansion bend is that the flexible compensation amount is big, the bearing temperature height, it is big to bear pressure, and present metallic conduit expansion bend generally adopts stainless steel to make bellows, when pipe expansion, corrugated stainless steel tubing is produced impact force, and pipeline will rupture when intensity reaches fatigue strength, if the weld bond of pipeline is easy to cracking and can't repairs when torque force is arranged.
Summary of the invention:
The objective of the invention is provides a kind of pipeline extension device at the problem of above-mentioned existence, can effectively resist impact force and torsion that pipe interior produces, and long working life.
Above-mentioned purpose realizes by following technological scheme:
Pipeline extension device, its composition comprises: the sleeve pipe that is connected with service pipe, has flange on the described sleeve pipe, be wound with packing between opposite side service pipe and the described sleeve pipe, the connecting tube that is enclosed within on the described opposite side service pipe is welded with gland, between described gland and the described flange by silk is connected.
Described pipeline extension device, the described packing outside has protective tube, and an end of described packing contacts with described flange, and the other end of described packing contacts with pressure pipe.
The end that described pipeline extension device, described opposite side service pipe are enclosed within described sleeve pipe the inside has baffle ring.
Beneficial effect:
1, the present invention adopts bushing type to connect, and by the built-in packing of protective tube, and adopts the design of pressure pipe and gland to prevent that liquid from flowing out before the packing, and tubule is convenient as the piston tube turnover during work, can effectively resist flexible that pipeline produces, and prevents the weld bond cracking.
, the present invention adopts flanged Placement can effectively alleviate the torque force that pipeline produces, so operating life prolongs greatly.
, service pipe and sleeve pipe break away from when baffle ring being set on the service pipe of the present invention and avoiding extending amount big.
, the present invention is simple in structure, easy to maintenance, not fragile.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
Embodiment:
Embodiment 1:
Pipeline extension device, its composition comprises: the sleeve pipe 1 that is connected with service pipe 2, has flange 3 on the described sleeve pipe, be wound with packing 4 between opposite side service pipe and the described sleeve pipe, the connecting tube 5 that is enclosed within on the described opposite side service pipe is welded with gland 6, between described gland and the described flange by silk 7 is connected.
Embodiment 2:
Described pipeline extension device, the described packing outside has protective tube 8, and an end of described packing contacts with described flange, and the other end of described packing contacts with pressure pipe, can prevent leakage by protective tube 8 intensified pressures.
Embodiment 3:
Described pipeline extension device, an end that is positioned at described bassoon the inside on the described tubule have baffle ring 9 service pipe and the disengaging of this product sleeve pipe when avoiding extending amount big.
Claims (3)
1. pipeline extension device, its composition comprises: the sleeve pipe that is connected with service pipe, it is characterized in that: have flange on the described sleeve pipe, be wound with packing between opposite side service pipe and the described sleeve pipe, the connecting tube that is enclosed within on the described opposite side service pipe is welded with gland, between described gland and the described flange by silk is connected.
2. pipeline extension device according to claim 1 is characterized in that: the described packing outside has protective tube, and an end of described packing contacts with described flange, and the other end of described packing contacts with pressure pipe.
