Abstract
The invention discloses a different-diameter butted pipe joint, which comprises a large-diameter joint, a small-diameter joint and a middle joint, wherein an externally protruded front sealing ring accommodating slot is formed at the head of the large-diameter joint; a front sealing ring is plugged in the front sealing ring accommodating slot; an externally protruded rear sealing ring accommodating slot is formed at the tail of the small-diameter joint; a rear sealing ring is plugged in the rear sealing ring accommodating slot; the middle joint comprises a front sleeve ring matched with the tail of the large-diameter joint and a rear sleeve ring matched with the head of the small-diameter joint; the front sleeve ring is connected with the rear sleeve ring through connected side surfaces to form a whole; an included angle between the bus of the connection side surface and the horizontal plane is 40 to 50 degrees; the tail of the large-diameter joint is butted and then welded with the front sleeve ring; and the head of the small-diameter joint is butted and then welded with the rear sleeve ring. A good sealing effect is achieved after the pipe joint is butted; and the large-diameter joint is butted with the small-diameter joint through the middle joint, so that the whole length of the different-diameter butted pipe joint is greatly reduced.
Description
Technical field
The present invention relates to a kind of reducing butt joint and use pipe joint.
Background technique
As shown in Figure 1, reducing docks the butt joint that is used for the different tube diameters pipe with pipe joint, generally comprises big drive connector 1 and path joint 2; Large-diameter pipe is filled in big drive connector 1; The path pipe is filled in path joint 2, connects through the plurality of sections connection tube between big drive connector 1 and the path joint 2, and the angle between connection tube side place bus and the horizontal plane is 12 °; Therefore need be than the connection tube of multistage; Like this then need carry out welding repeatedly, trouble very, and cause whole reducing butt joint long with pipe joint; When carrying out the butt joint of pipe in addition, the sealing between the pipe and joints also difficulty or ease guarantees.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing reducing butt joint with pipe joint, the present invention provide a kind of shorter, moulding is easier, the better reducing of sealability docks and uses pipe joint.
The technological scheme that the present invention solves its technical problem is: pipe joint is used in a kind of reducing butt joint; Comprise big drive connector and little drive connector; The head of said big drive connector is provided with the preceding seal ring receiving groove of outer arch; Be plugged with preceding seal ring in the seal ring receiving groove before described, described before the seal ring protrusion before described outside the seal ring receiving groove;
The afterbody of said little drive connector is provided with the back seal ring receiving groove of outer arch, is plugged with the back seal ring in the seal ring receiving groove of described back, and described back seal ring protrusion is outside the seal ring receiving groove of described back;
Also comprise transition joint; Described transition joint comprise the front ferrule adaptive with the afterbody of described big drive connector, with the adaptive back lasso of head of said little drive connector; Be integral through being connected side linking between described front ferrule and the back lasso, the bus of said connection side and the angle between the horizontal plane are 40 ° ~ 50 °;
The afterbody of said big drive connector docks the back welding with described front ferrule, the head of said little drive connector docks the back welding with described back lasso.
Further, the bus and the angle between the horizontal plane of said connection side are 45 °.
The present invention in use, and is the same with pipe joint with existing reducing butt joint, and large-diameter pipe is filled in big drive connector, and the path pipe is filled in little drive connector.After large-diameter pipe is filled in big drive connector because preceding seal ring protrusion is described before outside the seal ring receiving groove, therefore before seal ring can produce deformation, thereby the generation sealing effect; Same, after the path pipe was filled in the path joint, because the back seal ring protrudes outside the seal ring receiving groove of described back, therefore the back seal ring can produce deformation, thereby produces sealing effect.
Beneficial effect of the present invention is: dock the back good sealing effect; Adopt transition joint to carry out the butt joint of big drive connector and little drive connector, shortened the entire length of reducing butt joint greatly with pipe joint.
Description of drawings
Fig. 1 is the structural representation of existing reducing butt joint with pipe joint.。
Fig. 2 is a structural representation of the present invention.
Fig. 3 is the deformation schematic representation of seal ring before large-diameter pipe is filled in behind the big drive connector.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
With reference to Fig. 2, Fig. 3; Pipe joint is used in a kind of reducing butt joint; Comprise big drive connector 1 and path joint 2; The head of said big drive connector 1 is provided with the preceding seal ring receiving groove 3 of outer arch, is plugged with preceding seal ring in the seal ring receiving groove 3 before described, described before the seal ring protrusion before described outside the seal ring receiving groove 3.
The afterbody of said path joint 2 is provided with the back seal ring receiving groove 4 of outer arch, is plugged with the back seal ring in the described back seal ring receiving groove 4, and described back seal ring protrusion is outside described back seal ring receiving groove 4.
Also comprise transition joint 5; Described transition joint 5 comprise the front ferrule 6 adaptive with the afterbody of described big drive connector 1, with the adaptive back lasso 7 of head of said path joint 2; Be integral through being connected side 8 linkings between described front ferrule 6 and the back lasso 7; The bus of said connection side 8 and the angle between the horizontal plane are 40 ° ~ 50 °, and in the present embodiment, the bus and the angle between the horizontal plane that connect the side are 45 °.
The afterbody of said big drive connector 1 docks the back welding with described front ferrule 6, the head of said path joint 2 docks the back welding with described back lasso 7.
The present invention in use, and is the same with pipe joint with existing reducing butt joint, and large-diameter pipe 9 is filled in big drive connector 1, and the path pipe is filled in little drive connector.After large-diameter pipe 9 is filled in big drive connector 1 because preceding seal ring 10 protrusions are described before outside the seal ring receiving groove 3, therefore before seal ring 10 can produce deformation, thereby the generation sealing effect; Same, after the path pipe was filled in the path joint, because the back seal ring protrudes outside the seal ring receiving groove of described back, therefore the back seal ring can produce deformation, thereby produces sealing effect.
