The mouth of pipe；
One small-bore liner oil pipe, the small-bore liner oil pipe includes a small-bore oil pipe main body, in small-bore oil pipe
Main body is built-in with small-bore internal lining pipe, and small-bore internal lining pipe forms flange at the mouth of pipe of small-bore oil pipe along oil pipe radial direction flange
The mouth of pipe；
The heavy caliber liner oil pipe and small-bore liner oil pipe are matched somebody with somebody by liner oil connection and liner tubing coupling
Close and realize connection.
Further, the liner oil connection include a linkage section A and being connected with heavy caliber liner oil pipe with it is small
The connected linkage section B of bore liner oil pipe, and linkage section A bore of the bore more than linkage section B, have one in linkage section A
Hold the annular groove of heavy caliber liner oil pipe insertion, be threadedly coupled between the linkage section A and heavy caliber liner oil pipe, the company
Meet section B corresponding with small-bore liner oil pipe, and be connected by liner tubing coupling, the liner oil connection is also built-in with interior
Bushing pipe.
Further, the liner tubing coupling is sleeved on the outer end of small-bore liner oil pipe and liner oil connection, and
Fixation is connected through a screw thread, an abrasion-proof inner lining tube is also built-in with the centre position of liner tubing coupling, the wear-resistant liner pipe
There is a stepped internal lumen, the inner chamber is from the middle cavity gradually increased to both sides diameter.
The utility model has the advantage of：In the utility model, for heavy caliber liner oil pipe and small-bore liner oil
Pipe realizes connection using the cooperation between liner oil connection and liner tubing coupling, is ensureing heavy caliber liner oil pipe and osculum
On the basis of the liner oil pipe stable connection of footpath, the manufacture difficulty of liner tubing coupling is reduced, and liner tubing coupling is only needed
Coordinate small-bore liner oil pipe, reduce its overall size, it is ensured that follow-up work well.
For liner tubing coupling, by setting abrasion-proof inner lining tube, and its inner chamber be from centre to both sides diameter gradually
The cavity of increase, so cause small-bore liner oil pipe, liner oil connection when being connected with liner tubing coupling, make them it
Between connection can more consolidate, while the effect of wear resistant heat preserving can be played again.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram of liner oil pipe of the present utility model.
Specific embodiment
The following examples can make professional and technical personnel that the utility model is more fully understood, but therefore will not
The utility model is limited among described scope of embodiments.
A kind of liner oil pipe as shown in Figure 1, including
