Abstract
The utility model provides a steel pipe connecting device comprising a pipeline and a pipeline connector. A connecting opening of the pipeline connector is sequentially provided with an outer annular groove, an inner annular groove and a convex shoulder, wherein the outer annular groove is provided with a small hole for filling an adhesive; an annular groove which is matched with the outer annular groove on the pipe connector is arranged at the joint of the pipeline; and a sealing ring is arranged on the inner annular groove at the connecting opening of the pipe connector. The steel pipe connecting device disclosed by the utility model has the advantages of simple connecting process, good connecting effect, and the phenomena that air leakage and liquid leakage at the connector part can not happen.
Description
Technical field
The utility model relates to the pipeline connection technology field, particularly a kind of steel pipe connection set that is used for sheet-metal duct.
Background technique
Sheet-metal ducts such as existing steel pipe generally are to adopt welding method or adopt nut FERRULETYPE link to connect when connecting, the former complex process; The latter connects weak effect, and the joint is prone to leak gas, the phenomenon of leakage.
Summary of the invention
Existing complex process when the utility model adopts welding method to connect to existing pipeline; Existing connection weak effect when adopting nut FERRULETYPE link to connect; The joint is prone to leak gas, the deficiency of the phenomenon of leakage; Provide a kind of pipeline connection technology easy, good connecting effect, the joint can not leak gas, the steel pipe connection set of the phenomenon of leakage.
The technological scheme that the utility model adopts is accomplished through following mode: a kind of steel pipe connection set; It is characterized in that this steel pipe connection set comprises pipeline and pipe coupling; Double end straight pipe type pipe coupling or pipe coupling of double end bent tube type or bull pipe coupling are adopted in pipe coupling; Jointing in pipe coupling is provided with the outer ring groove, is provided with an aperture outside on the annular groove at least.
The utility model has also adopted following technological scheme:
The head of pipeline be provided with pipe coupling on the annular groove that matches of outer ring groove.
In the outer ring groove of pipe coupling, fill binder.
Inboard at the outer ring groove of the jointing of pipe coupling is provided with interior annular groove.
On the interior annular groove of pipe coupling, be provided with a seal ring.
On the jointing madial wall of pipe coupling, be provided with convex shoulder.
The utility model carries out the sheet-metal duct connecting means with existing employing welding method to be compared, and has sheet-metal duct and connects the easy characteristics of technology; The utility model carries out the sheet-metal duct connecting means with existing employing nut FERRULETYPE link to be compared, and has that sheet-metal duct good connecting effect, joint can not leak gas, the characteristics of the phenomenon of leakage.The utility model is particularly suitable for various sheet-metal ducts and when connecting, uses.
