Abstract

The utility model discloses a pipeline connecting assembly, and belongs to the technical field of pipeline connecting. The pipeline connecting assembly comprises a connecting part, seal rings and pressing rings. A central through hole is formed in a connecting part body, an annular protrusion is arranged on the inner wall of the through hole, the inner diameter of the annular protrusion is smaller than or equal to the outer diameter of a connected pipeline, the positions, close to the ports, of the two ends of the through hole are respectively provided with a section of internal threads, and the inner wall, between the annular protrusion and each section of internal threads, of the through hole is provided with a slope; the pressing rings are arranged at the two ends of the connecting part body respectively and respectively provided with an axial penetrating hole, the outer peripheral faces of the pressing rings are provided with external threads matched with the internal threads, and the seal rings are arranged between the pressing rings and the annular protrusion. The connecting part is connected with the pipeline in a sealed mode through axial compression and radial expansion of the seal rings by the pressing rings, and the pipeline connecting assembly is easy, convenient and rapid to assemble and disassemble and good in seal performance and will not affect circulation amount of the pipeline.

Description

A kind of pipeline connection part
Technical field
The utility model belongs to pipeline interconnection technique field, especially relevant with a kind of pipeline connection part.
Background technique
Existing many machinery need to be used pipeline and carry liquid or the gas that pressure is higher when work, but often because needs or the environmental constraint of construction, make the distant of machinery and construction location, carry the pipeline of liquid or gas to be formed by connecting by multistage pipeline, therefore the connection sealing between each section of pipeline requires very high, connection between existing pipeline adopts the mode of threaded sleeve conventionally, but when practice of construction, some pipeline does not arrange screw thread, just need to use special pipeline jointing construction and carry out connecting between pipeline.For adapting to the connection between the pipeline that screw thread is not set, in number of patent application 201210260329.2, mention a kind of pipeline jointing construction, comprise the link that two ends are communicated with, the first pipeline connecting end and the second pipeline connecting end, the threaded main body of middle part bit strip of described link, the two ends of described main body are cone, two bolts are installed in described main body, between described bolt and the cone of respective side, elastic ring body is installed, by first cone being stretched in the first pipeline connecting end, then turn bolt, bolt is moved to cone direction, promote elastic ring body and fill up the first pipeline connecting end, space between bolt and cone, thereby realize being tightly connected between link and the first pipeline connecting end, equally, again link and the second pipeline connecting end are tightly connected, but such Placement, because the cross-sectional flow area in link is less than the flow cross of the first pipeline and the second pipeline, liquid or gas flow flux in pipeline are reduced, affect pipeline using effect, two ends due to connector main body are cone in addition, described bolt and elastic ring body need to first be installed on the screw thread of main body, and then at main body two ends, cone are installed, troublesome poeration, and the coaxality of cone and main body is difficult to guarantee, affect connection sealing.
Model utility content
The purpose of this utility model is intended to overcome above-mentioned defect, provides that a kind of pipeline is easy to connect, connection sealing good and does not affect the connection part of pipeline discharge value.
For this reason, the utility model is by the following technical solutions: a kind of pipeline connection part, comprise link, seal ring and pressure ring, it is characterized in that, described link body is provided with central through bore, is provided with annular projection on through-hole wall, the internal diameter of annular projection is not more than the external diameter of connecting pipeline, during for connecting pipeline, pipeline is played to axially locating effect, through hole two ends are respectively arranged with one section of internal thread near port position, and the through-hole wall between annular projection and described internal thread is provided with inclined-plane, described pressure ring is arranged at respectively described link body two ends, pressure ring is provided with axial through bore, pressure ring outer circumferential face is provided with the outside thread matching with described internal thread, described seal ring is arranged between described pressure ring and described annular projection, when the first pipeline connecting end is installed on described link one end, the first pipeline connecting end is successively through described pressure ring, described seal ring, the first pipeline connecting end end is resisted against on the end face of described ring projection one end, by rotation pressure ring, the outside thread on pressure ring is threaded with the internal thread of described this end of link, pressure ring inner end applies axial force to seal ring, make seal ring carry out axial compression between the outer circumferential face of the first pipeline connecting end and described central through bore inclined-plane, radial expansion, realize being tightly connected of the first pipeline connecting end and described link, again the second pipeline connecting end and the link the other end are connected and sealed in above-mentioned same mode.
Use the utility model can reach following beneficial effect: by pressure ring, to the axial compression of seal ring, radial expansion, realize being tightly connected between link and pipeline, installing/dismounting simple and fast, good seal performance, and can not affect pipeline discharge value.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises link 1, seal ring 2 and pressure ring 3, described link 1 body is Hexagon cylinder, link 1 body is provided with central through bore, on through-hole wall, be provided with annular projection 7, the internal diameter of annular projection 7 is not more than the external diameter of connecting pipeline, during for connecting pipeline, pipeline connecting end is played to axially locating effect, through hole two ends are respectively arranged with one section of internal thread 6 near port position, and the through-hole wall between annular projection 7 and described internal thread 6 is provided with inclined-plane, described pressure ring 3 is arranged at respectively described link 1 body two ends, pressure ring 3 is provided with axial through bore, pressure ring 3 outer circumferential faces are provided with the outside thread 5 matching with described internal thread 6, pressure ring 3 one end radially evagination form end face shoulder, the cross section of end face shoulder outer circumferential face is Hexagon, instrument easy to use during installation, described seal ring 2 is arranged between the threaded end and described annular projection 7 of described pressure ring 3, seal ring 2 outer circumferential faces are provided with the gradient corresponding with described inclined-plane, seal ring 2 axial lengths are greater than the axial length on link 1 through-hole wall inclined-plane, when the first pipeline connecting end 4 is installed on described link 1 one end, the first pipeline connecting end 4 is successively through described pressure ring 3, described seal ring 2, the first pipeline connecting end 4 ends are resisted against on the end face of described ring projection one end, by rotation pressure ring 3, the outside thread 5 on pressure ring 3 is threaded with the internal thread 6 of described link 1 this end, pressure ring 3 inner ends apply axial force to seal ring 2, make seal ring 2 carry out axial compression between the outer circumferential face of the first pipeline connecting end 4 and described central through bore inclined-plane, radial expansion, realize being tightly connected of the first pipeline connecting end 4 and described link 1, again the second pipeline connecting end 8 is connected and sealed in above-mentioned same mode with link 1 the other end.
