Description
Technical field
The invention belongs to technical field of pipeline connection, the pipeline exchanging structure being related in hot-water heating facility, more particularly, to
Plant isometrical pipe connecting structure.
Background technology
At present, plastics (PP-R) the pipe fitting kind in hot-water heating market has a lot, and general rigid pipeline on the corner needs to pass through
Two-way pipe fitting is transferred, and then needs to be transferred by pipelines such as threeway, four-ways at pipe branch.Under normal circumstances, metal two
Logical, threeway, four-way pipe fitting interface diameter can be more than the pipe nozzle diameter that need to connect, and both are threaded connection, but plastics
Pipe fitting and pipe are poor due to processing characteristics, should not be using threaded connection.With people to the quality requirement of industrial products gradually
Improve, occur in that possess good looking appearance, equal tee many advantages, such as surfacing is smooth, lightweight, texture is good；To enter one
Step improves the contour structures of pipeline, reduces the resistance that flows in the duct of liquid, further occur in that two isometrical pipes connections with
And the structure that equal tee is connected with isometrical pipe, this structure is in connection generally by special hot melting equipment connection, general
Two pipes and pipe fitting heat melting to a certain extent simultaneously, while inserting one or two connection for bbreather pipe two ends, you can complete connection.It is this
The advantage of connection is that pipe fitting is solid and reliable with pipe junction, can bear hydraulic pressure considerably beyond use requirement and national standard
Require, and sealing effectiveness is preferably, junction is less prone to drainage.
But hot melting plastic pipe fitting is connected with isometrical pipe and is disadvantageous in that, on the one hand, need auxiliary by special equipment
Help, operation is inconvenient, particularly when high-altitude is installed or narrow space is installed, installment work will become more difficult；It is another
Aspect, two equal pipes are also required to by pipe joint when connecting so that contour structures are relatively too fat to move；Further, since the technique of hot melt
Demand, while to ensure that pipe fitting junction firmly, need to ensure thicker pipe thickness so that the materials of pipe fitting are more, increased
Production cost.
The content of the invention
In order to solve the above problems, the invention provides a kind of isometrical pipe connecting structure, it is easy to connect to have reached installation, close
Envelope is good, reduced outline, reduces the effect of tube material consumption.
The present invention is achieved by following technical solution.
A kind of isometrical pipe joint structure, including pipe fitting and pipe, described pipe one end are connected with pipe fitting, the pipe fitting with pipe
Exterior seal ring and inner seal ring are provided between the joint face of son, be provided with the contact surface of pipe fitting and pipe clearly groove structure and
The bulge-structure corresponding with groove structure.
The pipe fitting outer wall is provided with rib；The rib is radially extended, and is circumferentially uniformly distributed along tube wall.
The inner seal ring is located in the pipe fitting of pipe fitting between the pipe outer step end face of step end face and pipe；It is described outer
Sealing ring is located between the pipe fitting joint end end face and the joint for pipe end end face of pipe of pipe fitting；The pipe fitting joint end is more than pipe
Part external diameter, joint for pipe end external profile diameter are more than tube outer diameter.
The groove structure is dovetail groove A, circumferentially distributed along pipe fitting inner wall；The groove structure is arc groove B,
It is circumferentially distributed along pipe fitting inner wall；The bulge-structure is the swallow-tail form buckle A corresponding with groove A, is circumferentially divided along tube outer wall
Cloth；The bulge-structure is the arc buckle B corresponding with groove B, circumferentially distributed along tube outer wall.
The invention has the beneficial effects as follows：
A kind of isometrical pipe joint structure of the present invention, by arranging groove structure in pipe fitting inner wall, and outside pipe
Wall arranges bulge-structure, is coordinated with bulge-structure by groove structure, and without the need for aid, reach when pipe fitting is connected with pipe
The effect of convenient installation；It is by inner seal ring and exterior seal ring are respectively provided between pipe fitting and pipe joint face, inside and outside double
Resealing, it is to avoid liquid is leaked out from pipeline, also avoids the outer liquid of pipeline from penetrating in pipeline from pipe joint, has reached good
Good sealing effectiveness；Due to the hydraulic shock that often bears at pipe fitting and pressure it is maximum, therefore to meet pipe fitting intensity requirement,
Pipe fitting outer wall is provided with bead structures, it is ensured that while pipe fitting intensity, reduces material usage during formation of tubes；In addition, being
Ensure the intensity requirement at pipe fitting joint end and joint for pipe end, two tip sides have been carried out thickening design, pipe fitting is connected with pipe
Internal pipeline and outer wall junction are all only a connecting sewing afterwards, and fluids within pipes resistance is little, and pipeline contour structures are simple, beautiful
