Description
Technical field
This utility model is related to building pipe field, and in particular to a kind of flexible pipe pipe fitting.
Background technology
With the development of building pipe technology, flexible pipe so that its production and transport is convenient, construction is flexible, application extensively,
The low advantage of installation cost, is increasingly becoming market mainstream tubing.At present the flexible pipe of main flow have PAP, PE-X pipes,
PE-RT pipes, PB pipes, PE pipes etc..The connected mode of such tubing is numerous, has pincers-pressed type to connect, and representative prior art such as authorizes public affairs
Announcement number is CN 2510708Y's《A kind of plastic-aluminum combined effective clipper type plastic pipe fitting》；Hot-melt adhesive paste, such as notification number CN
202203579U's《The connected structure of heat molten type pipe connecting piece and PPR pipe》；Sliding compact form connection, such as CN 2620158Y《Plastic tube
Attachment structure》.The fitting structure of prior art, at connection tubing, because of reasons in structure flow area necking, pipeline flow amount
Influenced to different extents, sliding tight type pipe fitting flow area reduces more than 8%, and hot melten type pipe fitting reduces more than 10%, especially
It is clamper tube part, flow area reduces more than 20%.
The content of the invention
A kind of defect that this utility model is present with pipe fitting for existing flexible pipe, there is provided the flexible pipe enlarging peace of full-bore
Tubulature part, solves the problems, such as existing pipe fitting connection necking.This structure can optimize pipeline hydraulic flow resistance, and practicality is high, with market
Promotional value.
For achieving the above object, this utility model is employed the following technical solutions：
Pipe fitting is installed in a kind of flexible pipe enlarging, including an at least externally threaded main pipe body in one end, also including one with it is outer
The supporting thread cap of screw thread, is provided with a ramp structure in outer flighting front end, is provided with more than two and incrementally increases on ramp structure
Ring-type profile of tooth；Also include a collar, collar head has an annular boss, and annular boss is provided with outer inclined-plane structure, in outer inclined-plane
Structure is provided with more than two annular grooves for progressively reducing；Annular groove coordinates the pipe after fit sealing expander with ring-type profile of tooth
Material；Endoporus of the endoporus of ring tooth shaped position not less than tubing；Propulsion packing ring is provided between thread cap and the annular boss of collar
With resilient dish-shaped pad.
The technical scheme that this utility model can also be adopted：
Above-mentioned collar afterbody internal diameter is more than tube outer diameter；Collar middle part internal diameter is less than tube outer diameter, in collar
Between position inwall on be additionally provided with barb recesses.
Pipe fitting is installed in a kind of flexible pipe enlarging of the present utility model, by the annular in main pipe body ring-type profile of tooth and collar
Flexible pipe occlusion sealing after enlarging is realized the connection of full-bore by fit structure of groove etc., and ramp structure is matched somebody with somebody with tubing
Close closely smooth, reduce flow resistance；Dish-shaped pad energy sustained release fastens elastic force, and pipeline attachment security reliability, practicality are higher, real
Apply conveniently.
Description of the drawings
Fig. 1, this utility model cross section structure diagram in application；
Fig. 2, stereo decomposing cross-sectional schematic of the present utility model；
Specific embodiment
Pipe fitting embodiment is installed to flexible pipe enlarging of the present utility model with reference to the accompanying drawings to be described further.
Pipe fitting is installed in flexible pipe enlarging as shown in Figure 1, 2, and main pipe body 1 is a female adapter, is set in main pipe body 1
There is an external screw thread 10, also including one and the supporting thread cap 2 of external screw thread 10.A ramp structure is provided with the front end of external screw thread 10
11, four ring-type profiles of tooth 12 for incrementally increasing are provided with ramp structure 11；Also include a collar 3,3 head of collar has one annular
Boss 30, annular boss 30 are provided with outer inclined-plane structure 31, and four annular grooves for progressively reducing are provided with outer inclined-plane structure 31
32；Annular groove 32 coordinates the tubing 9 after fit sealing expander with ring-type profile of tooth 12；The endoporus 13 of 12 position of annular profile of tooth is not little
In inner hole of pipe 90；Propulsion packing ring 4 and resilient dish-shaped pad 5 are provided between the annular boss 30 of thread cap 2 and collar 3.
Main pipe body 1 can be elbow, threeway etc., and at least one end is provided with external screw thread 10.Ring-type profile of tooth 12 and annular groove
32 can do quantity according to pipe fitting specification adjusts, more than two, to guarantee sealing and anti-pull-out property.
To realize the all-pass run-off of pipe fitting connection, the endoporus 13 of 1 ramp structure 11 of this main pipe body is not less than in tubing
Hole 90, and ramp structure 11 fitted with inner hole of pipe 90 closely smoothness, reduces flow resistance, it is different from the undergauge structure of prior art.
Tubing of the present utility model 9 belongs to flexible pipe, such as PEX, PE-RT, aluminium-plastic pipe, PB etc. with suppleness and can expand
The tubing of mouth, then loses this effect with respect to the tubing with certain rigidity such as copper tube, PPR pipe, PVC.
Pipe fitting is installed in flexible pipe enlarging of the present utility model, compared with the pipe fitting in the existing field, by ring-type profile of tooth with
Flexible pipe occlusion sealing after enlarging is realized the connection of full-bore, inclined-plane by fit structure of the annular groove on collar etc.
Structure and tubing coordinate closely smooth, reduce flow resistance, and can reduce legionella grow space；Dish-shaped pad energy sustained release is tight
Gu elastic force, pipeline attachment security reliability, practicality are higher, easy to implement, with market popularization value.
