Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises pipe fitting 1, interface arrangment and seal ring 4, and pipe fitting 1 comprises end 11 and delivery section 12, and described interface arrangment and seal ring 4 all are arranged on the inwall place of pipe fitting 1.In use, the pipeline that need are connected inserts in the pipe fitting 1, and this moment, the inwall of pipe fitting 1 just fitted with the outer wall of pipeline, and pipeline is compresses seal 4 just in time, thereby makes that pipeline obtains sealing, and pipeline passes interface arrangment, thereby is connected in the pipe fitting 1.Interface arrangment can be self-locking structures such as resilient key, back-off structure.Pipe fitting 1 can be elbow, threeway or adapter sleeve, adapter sleeve for example, and two ends that two pipelines are inserted pipe fitting 1 respectively then, the two ends of pipe fitting 1 are respectively arranged with seal ring 4 and interface arrangment.The quantity of seal ring 4 and interface arrangment is decided according to connection request, and promptly only needing needs the place of connecting tube that seal ring 4 is set and interface arrangment gets final product at pipe fitting 1.By said structure, need not to re-use other instruments during connecting tube, only the pipeline insertion need be put in place gets final product, and this just makes that construction is very convenient, even also can smooth construction in the field of shortage power source.
For simplified structure, as Fig. 2, shown in Figure 6, interface arrangment is the back-off circle 5 that is provided with the tooth 51 that curves inwardly.The tooth 51 of back-off circle 5 curves inwardly, and just to the center line bending of pipe fitting 1, pipeline is just bitten by tooth 51 after insertion, thereby fixes pipeline, prevents that pipeline from being pulled or rocking.Back-off circle 5 can embed in the pipe fitting 1, also can be to be threaded onto pipe fitting 1 inwall, and back-off circle 5 is simple in structure, and changes easily.
For the ease of safeguarding, as Fig. 1, Fig. 2 and shown in Figure 5, also comprise the sealing cover 3 of annular, sealing cover 3 is connected the end 11 of pipe fitting 1, and the inwall of described sealing cover 3 is provided with and the suitable depression 6 of seal ring 4 shapes.Seal ring 4 in use may wear out or damage, and at this moment just needs to safeguard to handle, and according to said structure, when safeguarding, only need take sealing cover 3 apart, promptly replaceable seal ring 4, and this just makes that maintenance in the future is simpler.Sealing cover 3 and pipe fitting 1 can be by being threaded, also can be by press-fiting connection.
For the ease of changing interface arrangment, as Fig. 1, Fig. 2 and shown in Figure 4, also comprise the vinyl cover 2 of tubulose, described vinyl cover 2 is connected the end 11 of pipe fitting 1, described sealing cover 3 is installed between vinyl cover 2 and the pipe fitting 1, and described interface arrangment is installed between vinyl cover 2 and the sealing cover 3.Vinyl cover 2 can be by being threaded in end 11, also can or press-fit connection by buckle, the quantity of the quantity of vinyl cover 2 and sealing cover 3 should be decided according to the kind of pipe fitting 1, and for example pipe fitting 1 is a three-way joint element, then needs three vinyl covers 2 and three sealing covers 3.In maintenance process, at first pull down vinyl cover 2, thereby can change interface arrangment, if also need change seal ring 4, then continue to pull down sealing cover 3.Just can safeguard easily that thus pipe fitting 1 also can be recycled.
For the ease of regulating the link position of vinyl cover 2 and pipe fitting 1, vinyl cover 2 and pipe fitting 1 are connected by screw thread.Vinyl cover 2 just can so just can be regulated the degree that compresses of seal ring 4 by the relative position of threaded adjusting and pipe fitting 1, promptly in axial compression seal ring 4, seal ring 4 is fitted at circumferential and pipeline, thereby seal better.When construction, just can control the degree that compresses of seal ring 4 like this, reach the sealing effect that needs.
Electro-fusion sleeve and hot melt butt joint can produce very big weld marks, thereby make pipeline change at the connection part internal diameter, thereby make the fluid instability, for avoiding the problems referred to above, as depicted in figs. 1 and 2, end 11 is complementary with corresponding outer diameter tube, and described delivery section 12 is complementary with the internal diameter of pipeline.This is after pipeline inserts end 11, and its outer wall can cooperate with the inwall of end 11, thereby is blocked by interface arrangment, sealed circle 4 sealings; And the inwall of pipeline is communicated with the inwall of delivery section 12, and internal diameter just can not change.Therefore the conveying of fluid is more stable.
On the basis of abovementioned technology, pipe fitting 1 is made of copper.Therefore pipe fitting 1 had both had rigidity preferably, guaranteed can not be out of shape when mounted; Also have corrosion resistance preferably, guarantee working life.
In order to guarantee the rigidity of vinyl cover 2, vinyl cover 2 is made by polycarbonate (PC).Polycarbonate (PC) has stronger rigidity, and this has just guaranteed can compress interface arrangment and sealing cover 4 when connecting.
