Abstract
The utility model discloses a novel steel-plastic transition pipe. The novel steel-plastic transition pipe comprises a plastic pipe and a steel pipe. The plastic pipe is bent, one end of the plastic pipe is fixedly connected with the steel pipe, and a fixing base is arranged at the bending portion of the plastic pipe. The bending portion of the steel-plastic transition pipe is arranged on the plastic pipe, and due to the fact that the bending performance of the plastic pipe is higher than that of structural steel, breakage and leakage do not occur at the bending portion easily. Due to the fact that the fixing base is arranged at the bending portion, the steel-plastic transition pipe can be vertically arranged on a horizontal plane through the fixing base, and installation is convenient.
Description
Technical field
The utility model relates to Stainless Steel Tube and the pipeline parts connecing is refuted in plastic tube transition, and particularly a kind of steel is moulded transition fitting.
Background technique
At present, underground introduction pipe line and the surface line of China's pipeline gas industry, generally adopt steel to mould the rigid connection after transition.The connecting tube of under ground piping and surface duct at present, traditional way, the electric smelting threeway that before general employing building, house steward PE63 welds a PE63X32X63, the inlet tube that mates the PE32 of welding with PE63 locates to install the electric smelting elbow of a PE32X32 of welding beyond building foundation again, elbow is vertically located welded and installed steel and is moulded transition tube, is incorporated into indoor by the screwed connection of steel pipe.
In the patent document that the structure of moulding transition tube for steel is " CN2572188Y " at license notification number, disclose, steel is moulded the bend pipe that transition tube is roughly 90 °, have by steel pipe bend bend pipe in 90 ° and at least molding and forming at the plastic tube of bend pipe one end.Because steel pipe receives that in bending place the reason of larger stress causes in long-term using process, easily there is the problem that fracture is revealed in this bending place, there is larger potential safety hazard, and while installation, directly steel being moulded to transition tube places on the ground, inconvenience very for installing, is therefore necessary the problems referred to above to improve.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of Novel steel/plastic transition tube.
The utility model is achieved by the following technical solution: a kind of Novel steel/plastic transition tube, comprise plastic tube and steel pipe, and described plastic tube bending, is connected with steel pipe in one end of described plastic tube, in the bending place of described plastic tube, fixed base is set.
In technique scheme, described plastic tube is directly injected and molded in described steel pipe.
In technique scheme, on the outer wall of one end that described steel pipe is connected with described plastic tube, be provided with helical teeth.
In technique scheme, described plastic tube is polyethylene pipe or steel frame polyethylene compound pipe.
The utlity model has following beneficial effect: be arranged on plastic tube by the position of steel being moulded to transition tube bending, because plastic tube material bending performance is far above shaped steel, therefore bending place is not easy to occur fracture and reveals, and owing in bending place, fixed base being set, steel is moulded transition tube and can be vertically placed on horizontal plane by fixed base, installs more convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Embodiment
Below the utility model is described in further detail.
Embodiment 1: referring to Fig. 1 to Fig. 2, a kind of Novel steel/plastic transition tube, comprises plastic tube 2 and steel pipe 1, and described plastic tube 2 bends, and is connected with steel pipe 1 in one end of described plastic tube 2.By kink being arranged on the good plastic tube of bending performance, therefore in use steel is moulded transition tube bending place and is not easy to occur fracture and the problem of revealing.
Described plastic tube 2 is directly injected and molded in described steel pipe 1, ensure that plastic tube 2 and steel pipe 1 fixing position have good sealability, and be provided with helical teeth 10 on the outer wall of the one end being connected with described plastic tube 2 at described steel pipe 1, the opposite direction that the direction of this helical teeth 10 and steel pipe 1 insert, plastic tube 2 injection mouldings are in the time of described steel pipe 1, by the cooperation of helical teeth 10 and plastic tube 2 inwalls, steel pipe 1 can not deviate from from plastic tube 2.
In the bending place of described plastic tube 2, fixed base 20 is set, in the time that steel is moulded transition tube installation, can it be directly vertically placed on to ground by fixed base 20, it is more convenient to make to install.
Embodiment 2: on described steel pipe 1, screw thread is set, one end that described plastic tube 2 is connected in described steel pipe 1 is tapped hole, and described steel pipe 1 is fixed in described plastic tube 2 by the cooperation of screw thread and tapped hole, embodiment 2 all the other with embodiment 1.
In above-described embodiment, plastic tube 2 adopts polyethylene pipe or steel frame polyethylene compound pipe, has very high decay resistance when having higher-strength, has ensured that steel moulds the working life of transition tube.
