Abstract
The utility model relates to an expandable pipeline connecting device which comprises an expansion pipe. One end of the expansion pipe is provided with a taper hole opening, and the external cylinder surface of the end is provided with screw threads; a sealing ring which is a taper ring made of elastic material and arranged in the taper hole opening of the expansion pipe; an anti-drawing tight loop which is an opening taper ring and the bottom face of the anti-drawing tight loop is butted against the bottom face of the sealing ring; one end of a clamp nut and the expansion pipe are in screw thread connection and the other end is provided with a taper hole corresponding to the conical face of the anti-drawing tight loop. A pipeline can do the axial displacement and the relative rotation in the sealing ring under the action of external force after the pipeline is arranged, and thus the interface of the pipeline can be prevented from breaking.
Description
The utility model relates to a kind of assembling pipe joint, is specifically related to a kind of telescopic assembling pipe joint.
The pipeline of prior art connects system and adopts hard connecting modes such as welding, be threaded.Because the difference of environmental conditions, this Placement exists certain narrow limitation and shortcoming.For example, can't carry out high quality welding to pipe joint in that the very little situation of space range is next.Be threaded if adopt, then make the intensity at pipe joint place reduce greatly, in case pipeline is subjected to the external force effect, then the pipe joint place is easy to generate breach or dark trace, causes the leakage of interior gas of pipeline or liquid.Particularly because factors such as ground, soil properties, newly constructed house all has the sedimentation period in 15 years, settling amount is from several centimetres to tens centimetres, especially in recent years phreatic continuous extraction, make the sedimentation in ground and house even more serious, because building settlement causes the fracture or the loosening gas leakage that takes place of gas pipe line, the major accident that causes casualties often takes place, and has caused great loss for the country and people's lives and properties.
Traditional coal gas is introduced pipeline and is all adopted screw thread and auxiliary packing to connect, as shown in Figure 1.When building 11 sedimentations and road surface 18 takes place when weight is arranged, easily rupturing in interface 12,13,14,15 and 16 places, causes gas leakage.
The purpose of this utility model is to provide a kind of telescopic assembling pipe joint, makes pipeline do the time spent and avoid the fracture of pipe joint effectively being subjected to external force, guarantees that the fluid that is transferred is not leaked.
For realizing above purpose, the utility model provides a kind of telescopic assembling pipe joint, is characterized in, comprise: a telescopic pipe, the diameter of bore of this telescopic pipe is greater than outer diameter tube, and an end of this telescopic pipe has conical orifice, and the outer cylinder surface of this end is provided with screw thread; One seal ring, in circular cone ring that sealing circle system employing elastic material is made and the conical orifice of being located at this telescopic pipe one end, the sealing circle also has an endoporus that can supply pipeline to wear; One resistance to plucking fastening ring, this resistance to plucking fastening ring system is by an open circles conical ring of making than hard material, and has an endoporus that can wear for pipeline, and the bottom surface of this resistance to plucking fastening ring leans on the bottom surface of sealing circle; One tightening nut, an end of this tightening nut is threaded with this telescopic pipe, and there is a taper hole in the other end central authorities, and the tapering of this taper hole is corresponding with the tapering of this resistance to plucking fastening ring, and has an end diameter that is slightly larger than outer diameter tube.
Owing to adopt above structure, when tightening nut is tightened on telescopic pipe, can make between telescopic pipe and the seal ring and between pipeline and the seal ring to reach sealing, thereby guarantee that the fluid that is transferred is not leaked; Simultaneously, owing to do the time spent and can in seal ring, do axial displacement and relatively rotate when pipeline is subjected to external force, so can avoid the fracture of pipe joint effectively.
Introduce preferred embodiment of the present utility model and application example below in conjunction with accompanying drawing, in the hope of more specifically understanding the purpose of this utility model, characteristics and advantage.
The accompanying drawing simple declaration:
Fig. 1 is that traditional coal gas is introduced the pipeline connection diagram;
Fig. 2 is the sectional arrangement drawing of the scalable pipeline connection set of the utility model one preferred embodiment;
Fig. 3 is applied to the connection diagram that coal gas is introduced pipeline for the scalable pipeline connection set of the utility model.
As shown in Figure 2, the scalable pipeline connection set of the utility model one preferred embodiment comprises a telescopic pipe 21, the diameter of bore of this telescopic pipe 21 is greater than the external diameter of pipeline 31, this endoporus appropriate position is provided with an internal projecting ring 22, the slightly larger in diameter of this internal projecting ring 22 is in the diameter of pipeline 31, one end of this telescopic pipe 21 has conical orifice 23, the outer cylinder surface of this end is provided with screw section 24, the diameter of this screw section 24 is greater than non-threaded 25 diameter, and the other end 26 places of this telescopic pipe 21 can adopt hard connecting modes such as welding, screw thread to be connected (not shown) with pipeline; One seal ring 41, sealing circle 41 are one to adopt in circular cone ring that elastic material makes and the conical orifice 23 of being located at aforementioned telescopic pipe 21 1 ends, and sealing circle 41 also has an endoporus that can wear for pipeline 31; One resistance to plucking fastening ring 51, this resistance to plucking fastening ring 51 are an open circles conical ring of being made by relatively hard materials, and its endoporus can wear for pipeline 31, and the bottom surface of this resistance to plucking fastening ring 51 leans on the bottom surface of sealing circle 41; One tightening nut 61, an end of this tightening nut 61 is connected with the screw section 24 of aforementioned telescopic pipe 21 1 ends, and there is a taper hole 62 in the other end central authorities, and the tapering of this taper hole 62 is corresponding with the tapering of aforementioned resistance to plucking fastening ring 51.
When tightening nut 61 is tightened on telescopic pipe 21, promptly the taper hole 62 by the other end moves inward resistance to plucking fastening ring 51 and the conical surface of seal ring 41 and the conical orifice 23 of telescopic pipe 21 is compressed, thereby reaches sealing between telescopic pipe 21 and seal ring 41; Make seal ring 41 compress pipeline 31 by dwindling of resistance to plucking fastening ring 51 internal diameters simultaneously, thereby between pipeline 31 and seal ring 41, reach sealing because of the radially component of reaction of the conical orifice 23 of telescopic pipe 21.
Do the time spent and can in seal ring 41, do axial displacement and relatively rotate when pipeline 31 is subjected to external force, and do not influence between telescopic pipe 21 and the seal ring 41 and the sealing between pipeline 31 and the seal ring 41.
Fig. 3 is that the scalable pipeline connection set of the utility model is applied to the connection diagram that coal gas is introduced pipeline.As shown in the figure, owing to adopted the scalable pipeline connection set of the utility model at each interface 72,73,74,75 and 76 places, when building 11 sedimentations or road surface 18 takes place when weight is arranged, interface 72,73,74,75 and 76 places all can and relatively rotate automatically by the displacement to axial between pipeline and the scalable pipeline connection set and adjust, thereby can avoid the fracture of pipe joint effectively, prevent the generation of accident to leak the coal gas.
