Description
Technical field
The utility model relates to technical field of pipeline connection, in particular to a kind of high-adaptability pipeline connecting structure.
Background technique
The fast and reliable interconnection technique of plastic conduit is always everybody focus of attention in industry, such as hot-melt adhesive paste side
Formula.There are clamping hoop type connection, sliding compact form connection, cartridge connection, fastly for the mode that not heat-fusible plastic conduit generallys use
The modes such as plug-in connection.For more simple and reliable connection, there is a kind of add using plastic conduit memory effect to remember in the prior art
Recall the contractile ring connection type of plastic production: its connecting pipe outer diameter is greater than plastic conduit internal diameter, and in connecting pipe appearance
Face is provided with multiple tracks protrusion seal ring, and when use covers upper one contraction with recovery characteristics plastic production outside plastic conduit
Then plastic conduit and contractile ring are expanded simultaneously with tool, enable its internal diameter be greater than connecting pipe outer diameter, then put on by ring
Connecting pipe, plastic conduit and contractile ring restore undergauge under memory characteristic after waiting for a period of time, and tightly hoop is in connecting pipe
On, while the concentric raised of connecting pipe outer surface plays seal ring and is embedded in plastic conduit inner wall, forms reliable sealing structure, simultaneously
Plastic conduit is prevented to be detached from from pipe fitting.
This mode has the characteristics of connection is reliable, construction is simple, however, to ensure that pipe fitting can smoothly be inserted into pipeline
It needs to diffuse into pipeline than needing larger-sized internal diameter, therefore need pipeline that there is biggish recovery to guarantee reliably to seal
Characteristic is not that good pipeline is relatively difficult to be applicable in, such as heat-proof polythene (PERT) is managed, aluminium-plastic pipe for some recovery characteristics
Equal memory characteristics pipeline not outstanding etc. is all difficult to be applicable in the technology, because these pipelines need excessive expander that could make pipe fitting
Insertion, and excessively expander will lead to these pipeline breaking.
Therefore, it is necessary to improve to solve the above technical problems the prior art.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of high-adaptability pipeline connecting structure and its expander to fill
It sets, connection is reliable and can be adapted for memory characteristic pipeline not outstanding.It is realized in particular by following technical scheme:
The high-adaptability pipeline connecting structure of the utility model, including Petrochemical Pipe Joints and to connecting pipe, the pipeline
Connector is entirely inserted into coniform, the Petrochemical Pipe Joints outer surface big in the small tail end radius of tip radius to the part of connecting pipe
On be provided with the bulge loop tail portion and top concentric with Petrochemical Pipe Joints the outer diameter of bulge loop be both greater than internal diameter to connecting pipe.
In optimal technical scheme, it is arranged fluted between two adjacent bulge loops, sealing ring is equipped in groove.
It further include the mechanical locking device being arranged in outside to connecting pipe in optimal technical scheme, the mechanical interlocking dress
Set the shell ring including being arranged in outside to connecting pipe and the locking nut for squeezing shell ring.
It further include the plastic shrink ring with shrinkage character being arranged in outside the pipeline in optimal technical scheme.
The invention also discloses a kind of pipe expander, the expander head of the pipe expander is in the small tail end of tip radius half
Big coniform of diameter, and the taper of the circular cone and above-mentioned Petrochemical Pipe Joints are inserted into and are adapted to the taper of connecting pipe part.
In optimal technical scheme, connecting pipe is treated using above-mentioned pipe expander and carries out expander, then by above-mentioned pipe
Road connector is inserted into connecting pipe.
The invention also discloses a kind of water segregators, carry out pipeline company using above-mentioned high-adaptability pipeline connecting structure
It connects.
The invention also discloses a kind of valves, carry out pipeline company using above-mentioned high-adaptability pipeline connecting structure
It connects.
The utility model has the beneficial effects that the high-adaptability pipeline connecting structure of the utility model, since pipeline being connected
Head insertion end conical design, while pipeline expander section is also taper-deformation, Petrochemical Pipe Joints can be inserted into always pipeline connection
Until head outer diameter bulge loop is contacted with inner wall of the pipe limit, so that subsequent pipeline deformed part can having lesser recovery deformation
Sealing structure is formed, excessive expander is not necessarily to when expander, even memory characteristic pipeline not outstanding will not rupture, so for
Memory characteristic is prominent and pipeline not outstanding can be applicable in, and connects more stable.Other beneficial effects of the utility model
It will be further detailed in conjunction with embodiment in detail below.

Specific embodiment
It is as shown in the figure: the high-adaptability pipeline connecting structure in the present embodiment, including Petrochemical Pipe Joints 5 and to connecting pipe
4, the Petrochemical Pipe Joints 5 are entirely inserted into the cone big in the small tail end radius of tip radius to the part of connecting pipe, pipeline
The bulge loop 8 concentric with Petrochemical Pipe Joints is provided on 5 outer surface of connector, the outer diameter of the bulge loop of tail portion is greater than to connecting pipe
Internal diameter, the bulge loop at top is also greater than the internal diameter to connecting pipe.Top orientation refers to that, towards the direction to connecting pipe, tail end is
The direction opposite with top.The top-direction of bulge loop 8 is set as the structure 9 with 5 bus of Petrochemical Pipe Joints in obtuse angle, caudal directions
It is set as with Petrochemical Pipe Joints bus at right angles or the structure 7 of acute angle, being inserted into convenient for Petrochemical Pipe Joints, and band connection pipeline is extensive
