At present, during pipeline construction, during butt welding of pipelines, mainly there is hoisting machine Tool cooperation is manually adjusted and the equipment of suiting one's training is adjusted two ways.For people Work adjusts the method for boil on the nape opposite the mouth, and efficiency is the lowest, and anthropic factor impact is big, and concentricity is difficult to standard Really control.Device for aligning pipeline, is that one is applied to feedwater piping, sewage pressure pipe etc. The boil on the nape opposite the mouth of steel-pipe welding and weld seam adjusting apparatus, can be with Quick aligning welded pipe line.At present The all kinds device for aligning pipeline occurred on market, has no extensively application, main cause Being that utensil is heavy, efficiency is low, operates loaded down with trivial details, and range is narrow, and price is more Expensive.During engineering construction, traditional construction appliance is difficult to operation by space constraints, specifically The technical problem that difficult, the weld seam adjustment difficulty of boil on the nape opposite the mouth etc. is difficult to overcome, Er Qiechuan is there is during operation 2-section pipe road is welded together by system exactly, and weld out-of-flatness easily tangles during use Foreign material form blocking, thus cause the problems such as booster.To this end, it is proposed that a kind of discharge Water steel-pipe welding contra-aperture device.

[utility model content]

Main purpose of the present utility model is to provide a kind of plumbing steel-pipe welding boil on the nape opposite the mouth dress Put, during use, protruded tube is inserted in a steel pipe through No. two union joints, utilizes rotation A number steel pipe and No. two steel pipes are tentatively coupled together by tight screw thread, then are tightened by bolts, even Junction can be sealed by the sealing ring in joint, will not leak, can be with efficient solution The certainly problem in background technology.

For achieving the above object, the technical scheme that this utility model is taked is:

A kind of plumbing steel-pipe welding contra-aperture device, including a steel pipe, No. two steel pipes, A number union joint, No. two union joints, a positioning key and protruded tube, a described steel pipe Side is fixing connects No. two union joints, and described No. two union joint sides are provided with No. two locking bodies, Described No. two union joints No. two positioning keys of internal fixing connection, inside described No. two union joints It is provided with No. two sealing rings, a number union joint of the fixing connection in described No. two steel pipe sides, described A number union joint side is provided with a locking body, and described locking body both sides are fixing to be connected Reinforcement, a described locking body and No. two locking bodies are by a bolt and No. two bolts It is connected, an a described union joint number positioning key of internal fixing connection, a described connection Head is internal is provided with a sealing ring, and described No. two steel pipes are through a fixing connection of union joint Protruded tube.

Further, it is provided with inside a described union joint and screws screw thread.

Further, the external diameter of described protruded tube 1.5mm less than the internal diameter of No. two steel pipes.

Further, a described locking body and No. two steel pipes are welding, described No. two locks Tight body and a steel pipe are welding.

Further, described No. two locking body quantity are two groups, and are distributed in a steel pipe Both sides, a described locking body quantity is two groups, and is distributed in the both sides of No. two steel pipes.

Compared with prior art, when this utility model has the advantages that use, Protruded tube is inserted in a steel pipe, simultaneously by 2-section pipe road boil on the nape opposite the mouth through No. two union joints Good, and can effectively prevent from tangling at plumbing fastener for connection foreign material, utilize and screw spiral shell A number steel pipe and No. two steel pipes are tentatively coupled together by stricture of vagina, the positioning key being positioned in union joint Can position when two joint steel pipes screw, facilitate locking body to dock, then use bolt Locking, junction can be sealed, will not leak by the sealing ring in union joint, this Utility model is novel in design, easy for installation, can effectively prevent at plumbing fastener for connection Blow-by, easily shelter evil people and countenance evil practices, tangle foreign material, form blocking, thus cause booster etc. Problem, and install easily, efficient and convenient.
