Abstract
The utility model relates to a pipe connecting device including a connecting sleeve that is sleeved on the outer walls of two nearby pipes; both the two ends of the connecting sleeve are sealed and connected with the two pipes; the inner wall of the connecting sleeve is firmly fixed with a limit tensioning rib; besides, one end of the connecting sleeve is provided with a flexible sealing ring that is sleeved on the outer wall of the pipes, while the other end of the connecting sleeve is sealed and firmly connected with the outer wall of the pipes. The device has the advantages of a simple structure and convenient fixing and positioning when used for connecting pipes; besides, the joint between pipes is unlikely to deform, break or have leakage due to centralized stress; therefore, the utility model is fit for connecting various pipes with large calibers.
Description
The utility model relates to a kind of connection set of fluid-transporting tubing, relates in particular to a kind of device that adopts link that the heavy caliber fluid line is connected.
At present, when laying fluid-transporting tubing, modes such as pipeline enlarging connection, the molten connection of electric heating or metal connecting piece connection are adopted in the connection between two pipe ends usually.Enlarging Placement wherein, owing to must carry out reaming in advance to an end of pipeline, and, common increase along with pipe diameter, the difficulty of its reaming processing also increases, therefore, this Placement mainly is applicable to the connection of small-bore fluid line, and is not very suitable for diameter greater than the connection between 400 millimeters the heavy caliber fluid line; The molten Placement of electric heating is exactly to interconnect by the port of electric heating with two pipelines, when being used for the installation of pipeline, must earlier the port of adjacent channel be aimed at, simultaneously, also to guarantee the weldquality of jointing during connection, if welding quality is bad, or the ground soft or hard under when construction pipeline is inhomogeneous, all may cause the joint of pipeline to deform, cracking and seepage, therefore, very inconvenient when this Placement is constructed in the open air, and require also very high to operator's technical merit.At present, diameter adopts the Placement of metal connecting piece usually greater than 400 millimeters heavy caliber fluid line, because of the intensity of metal connecting piece higher, pipe joint place after connecting is difficult for taking place cracking and seepage, simultaneously, the structure of link is simpler, therefore, in the connection of heavy caliber fluid line by more use; But owing to the link in this Placement is made by metallic material, so this link not too is applicable to the connection of plastic pipe; Simultaneously, this metal connecting piece structure is comparatively simple, therefore, is used for the connection construction of pipeline, and this link is comparatively difficult in the pipeline junction location, and construction control comparatively bothers.
The purpose of this utility model is to provide a kind of assembling pipe joint, this device can be used for the construction of diameter at the heavy caliber fluid line more than 400 millimeters, when being used for the pipeline connection, not only convenient but also reliable, and axial motion can not take place in the joint of pipeline in link, and the fluid line after being connected also is difficult for deforming, cracking or seepage.
For realizing the purpose of this utility model, a kind of assembling pipe joint, comprise to be set in the outer adapter sleeve of two adjacent tube walls, be respectively between the two ends of adapter sleeve and two pipelines and be tightly connected, on the inwall of described adapter sleeve, be set with spacing stiffening rib.
Advantage of the present utility model: this apparatus structure is simple, and during connecting tube, the installation of link and location are all very convenient; Pipeline junction can stress not concentrated and generation cracking or seepage, and can prevent to cause because of uneven settlement of foundation the inefficacy of pipeline connection preferably, and working life is longer; In addition, adopt plastic materials to make link, also can reduce the manufacture cost of this device, and be applicable to the connection of plastic pipe.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the sectional drawing of the utility model assembling pipe joint;
Fig. 2 is the stereogram of the utility model assembling pipe joint;
Fig. 3 is the stereo dissected figure of the utility model pipe connecting component.
1, pipeline, 2, adapter sleeve, 3, spacing stiffening rib, 4, elastic seal ring, 5, positioning groove.
As Fig. 1, shown in 2 and 3, a kind of assembling pipe joint, comprise and be set in the adapter sleeve 2 of two-phase outside pipeline 1 wall, this pipeline 1 is made by the plastic unit pipe, usually its diameter is more than 400 millimeters, adapter sleeve 2 also is made of plastics, its inwall is set with the spacing stiffening rib 3 of a circle annular, the internal diameter of adapter sleeve 2 one ends is a bit larger tham the external diameter of pipeline 1, the end of this end is provided with elastic seal ring 4, elastic seal ring 4 is set on the outer wall of pipeline 1 simultaneously, the internal diameter of adapter sleeve 2 the other end ends is then basic identical with the external diameter of pipeline 1, be mutually permanently connected by Plastic Welding between the outer wall of the end of adapter sleeve 2 and pipeline 1, also offer a circle seal ring positioning groove 5 on the outer wall at place, adapter sleeve 2 ends, the elastic seal ring 4 that is arranged on adapter sleeve 2 ends is embedded in this positioning groove 5.
In the utility model, pipeline 1 is made with the adapter sleeve 2 main plastics that adopt, and pipeline 1 cost of being made by this material is lower, and installation is also comparatively convenient; Certainly also can adopt other made such as metal.In addition, being connected between adapter sleeve 2 two ends and the pipeline 1 also can adopt elastic seal ring 4 to connect simultaneously, or it is fixedly connected to adopt Plastic Welding to carry out simultaneously, but its effect is slightly poorer than the foregoing description.
When using this assembling pipe joint connecting tube 1, adapter sleeve 2 is arranged between the two adjacent pipelines 1,3 of spacing stiffening ribs on adapter sleeve 2 inwalls are just between the end of two adjacent pipelines 1, the both sides of spacing stiffening rib 3 offset with the two-port of two pipelines 1 respectively, thereby two pipelines 1 are positioned, 4 pairs of elastic seal rings that the are arranged on connecting sleeve road 2 one ends wherein pipeline 1 of a side seal, simultaneously, the other end in connecting sleeve road 2 carries out fixing seal by Plastic Welding to the pipeline 1 of opposite side.
The utility model mainly is applicable to the connection of large diameter pipeline, is particularly useful for the connection of large-bore plastics pipeline.
