Abstract
The utility model discloses a kind of ready-package pipe joint, comprise bellows, interior Threaded Connector Coupling, tighten nut, cutting ferrule and seal washer, it is inner that seal washer is installed in interior Threaded Connector Coupling, cutting ferrule sandwiches on the bulge loop of bellows, the end of bellows is inserted in interior Threaded Connector Coupling inside and offsets with seal washer, tighten nut to be connected with internal thread joint screw thread, and tighten the inner end of nut and cutting ferrule offsets.The utility model by cutting ferrule with tighten coordinating of nut and realize and the quick assembling of interior Threaded Connector Coupling, its assembling is convenient, and the tensile strength of assembly structure is high, better tightness, safe and reliable.
Description
Technical field
The utility model relates to corrugated pipe connector technical field, especially relates to a kind of ready-package pipe joint.
Background technique
Bellows is widely used in inlet pipeline, fuel gas pipeline, warm hydrophone pipeline etc., and it has, and latus rectum is large, pressure-bearing is high, flexible corrosion resistant advantage.When usual bellows and joint assemble, after needing first the mouth of pipe of bellows to be carried out enlarging or otch, bellows could be connected with joint sealing, thus its operation is very inconvenient, and there is due to assembly structure problem the problem that tensile strength is not high and sealing is not strong in current pipe joint, easily causes and leak even potential safety hazard.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of ready-package pipe joint, by cutting ferrule with tighten coordinating of nut and realize and the quick assembling of interior Threaded Connector Coupling, its assembling is convenient, and the tensile strength of assembly structure is high, better tightness, safe and reliable.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of ready-package pipe joint, comprise bellows, interior Threaded Connector Coupling, tighten nut, cutting ferrule and seal washer, it is inner that seal washer is installed in interior Threaded Connector Coupling, cutting ferrule sandwiches on the bulge loop of bellows, the end of bellows is inserted in interior Threaded Connector Coupling inside and offsets with seal washer, tighten nut to be connected with internal thread joint screw thread, and tighten the inner end of nut and cutting ferrule offsets.
Wherein, described cutting ferrule comprises two the semicircle snap rings connected as one, and the end of these two semicircle snap rings is connected by joint.
Wherein, be connected by seal with O ring between described interior Threaded Connector Coupling with described deflation nut.
Wherein, the outer wall of described bellows is also coated with the plastic pipe matched with described deflation nut inner wall.Described deflation nut inner wall is also embedded with the cushion pad adapted with described plastic pipe.
Adopt after technique scheme, the utility model compared to the prior art advantageously:
Ready-package pipe joint described in the utility model, cutting ferrule sandwiches on the bulge loop of bellows, the end of bellows is inserted interior Threaded Connector Coupling inside and is offseted with seal washer, when tightening deflation nut, the active force tightening the inner end of nut puts on cutting ferrule, and by cutting ferrule, bellows is inwardly advanced, the port of bellows and seal washer are closely conflicted, realizes being tightly connected of bellows and interior Threaded Connector Coupling.Be be threaded owing to tightening nut with interior Threaded Connector Coupling, be fastened in interior Threaded Connector Coupling inner by the position-limiting action tightening nut, thus bellows has outside tensile strength preferably.The assembling of this ready-package pipe joint is convenient, and the tensile strength of assembly structure is high, better tightness, safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of cutting ferrule described in the utility model.
In figure, 1: interior Threaded Connector Coupling; 2: seal washer; 3: cutting ferrule; 4:O shape is enclosed; 5: cushion pad; 6: tighten nut; 7: bellows; 8: plastic pipe; 9: joint.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, is shown in shown in Fig. 1-2.
A kind of ready-package pipe joint, comprise bellows 7, plastic pipe 8, interior Threaded Connector Coupling 1, tighten nut 6, cutting ferrule 3, seal washer 2, O shape circle 4 and cushion pad 5, plastic pipe 8 is coated on the outer wall of bellows 7, and the external diameter of plastic pipe 8 matches with the internal diameter tightening nut, it is inner that seal washer 2 is installed in interior Threaded Connector Coupling 1, cutting ferrule 3 sandwiches on the bulge loop of bellows 7, cutting ferrule 3 is circular Al-alloy parts, cutting ferrule 3 comprises two the semicircle snap rings connected as one, the end of these two semicircle snap rings is connected by joint 9, preferably the connecting end surface of this joint 9 should be as far as possible little, so that easily two semicircle snap rings are broken into two with one's hands, during assembling, two semicircle snap rings are sandwiched on the bulge loop of bellows 7, its joint 9 two semicircle snap rings are linked into an integrated entity, element in transport assembly process is avoided to lose, the end of bellows 7 is inserted in interior Threaded Connector Coupling 1 inside and offsets with seal washer 2, tighten nut 6 to be threaded with interior Threaded Connector Coupling 1, enclose 4 by O shape between interior Threaded Connector Coupling 1 and deflation nut 6 to seal, and the inner end and the cutting ferrule 3 that tighten nut 6 offset, tighten on nut 6 inwall and be also embedded with the cushion pad 5 adapted with plastic pipe 8, when plastic pipe 8 passes deflation nut 6 with bellows 7, cushion pad 5 contacts with plastic pipe 8, play buffer-oriented effect.When tighten tighten nut 6 time, the active force of inner end tightening nut 6 puts on cutting ferrule 3, and is inwardly advanced by bellows 7 by cutting ferrule 3, and the port of bellows 7 and seal washer 2 are closely conflicted, and realizes being tightly connected of bellows 7 and interior Threaded Connector Coupling 1.Be be threaded owing to tightening nut 6 with interior Threaded Connector Coupling 1, cutting ferrule 3 is in interior Threaded Connector Coupling 1 inside by the position-limiting action tightening nut 6, and thus bellows 7 has outside tensile strength preferably.The assembling of this ready-package pipe joint is convenient, and the tensile strength of assembly structure is high, better tightness, safe and reliable.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
