Abstract
The utility model is related to the technical fields of connecting pipe, especially a kind of Concentric Reducers, including small diameter tube and large-diameter pipe, reducing joint is equipped among the small diameter tube and large-diameter pipe, the caliber at the reducing joint both ends is identical as the caliber of large-diameter pipe as small diameter tube respectively, the top of the small diameter tube and the tail end of large-diameter pipe are respectively equipped with card slot along the longitudinal direction, and the card slot upper wall is equipped with internal thread, and the card slot lower wall is equipped with external screw thread.35 slots are along the circumferential direction uniformly equipped on the lower wall of the card slot.The utility model, by the threaded connection in the card slot and card slot at big small diameter tube both ends, effectively increases the intensity of its interconnecting piece when connecting other pipelines, connection is reliable and good airproof performance, is not easy excessive, and the slot on card slot lower wall plays the role of drainage well, it is simple in structure, it is easy to use.
Description
Technical field
The utility model is related to the technical field of connecting pipe, especially a kind of Concentric Reducers.
Background technology
In petroleum chemical industry, pipeline transportation is essential.If during use, there are two pipes to be connected
Road diameter differs, then cannot achieve by welding by two tubing it is just right be connected to one piece, and realize and connect
Reduced pipe connection may be used in mouth effectively welded seal at this time, currently, when being connected using reduced pipe, generally using using
Pipeline is set on reduced pipe and is threadedly coupled, this connection type causes junction intensity low, the liquid spill of internal flow
Phenomena such as, reduce the effect used.
Utility model content
In order to overcome the shortcomings of that existing technology, the utility model provide a kind of Concentric Reducers.
Technical solution adopted by the utility model to solve its technical problems is：A kind of Concentric Reducers, including small diameter tube
And large-diameter pipe, be equipped with reducing joint among the small diameter tube and large-diameter pipe, the caliber at the reducing joint both ends respectively with path
Pipe is identical as the caliber of large-diameter pipe, and the top of the small diameter tube and the tail end of large-diameter pipe are respectively equipped with card slot along the longitudinal direction, institute
It states card slot upper wall and is equipped with internal thread, the card slot lower wall is equipped with external screw thread.
Another embodiment according to the present utility model further comprises along the circumferential direction uniform on the lower wall of the card slot
Be equipped with 3-5 slot.
The utility model has the beneficial effects that when connecting other pipelines, pass through the card slot and card at big small diameter tube both ends
Threaded connection in slot effectively increases the intensity of its interconnecting piece, connects reliable and good airproof performance, is not easy excessive, card slot lower wall
On slot play the role of drainage well, it is simple in structure, it is easy to use.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of the utility model one end.
1. small diameter tube in figure, 2. large-diameter pipes, 3. reducing joints, 4. card slots, 5. internal threads, 6. external screw threads, 7.
Slot.
Specific implementation mode
As shown in Fig. 1 and Fig. 2, a kind of Concentric Reducers, including small diameter tube 1 and large-diameter pipe 2, small diameter tube 1 and large-diameter pipe 2
Centre is equipped with reducing joint 3, and the caliber at 3 both ends of reducing joint is identical as the caliber of large-diameter pipe 2 as small diameter tube 1 respectively, small diameter tube 1
Top and the tail end of large-diameter pipe 2 be respectively equipped with card slot 4 along the longitudinal direction, 4 upper wall of card slot is equipped with internal thread 5,4 lower wall of card slot
It is equipped with external screw thread 6.Preferably, 3-5 slot 7 is along the circumferential direction uniformly equipped on the lower wall of card slot 4.
When the utility model is used, when connecting other pipelines, there are external screw thread, inner wall on the port outer wall of other pipelines
On have internal thread, due to 4 upper wall of card slot be equipped with internal thread 5,4 lower wall of card slot be equipped with external screw thread 6, other pipe ends are inserted
Enter and be threaded togather in card slot 4, effectively increase the intensity of its interconnecting piece, connects reliable and good airproof performance, be not easy
Excessive, the slot 7 being along the circumferential direction equipped on 4 lower wall of card slot plays the role of drainage well, simple in structure, easy to use.
