Description
Technical field
It the utility model is related to a kind of pipe fitting, more particularly to a kind of PE straight tubes special pipe fitting.
Background technology
PE pipes due to it is corrosion-resistant, connection is reliable, ageing-resistant, service life is long, wearability is good, small flow resistance excellent
Point, it is widely used in various pipelines, connecting pipe main at present is heat-melting butt-joint pipe fitting during use.Heat-melting butt-joint it is strong
Degree is higher than body bulk strength, but forms butt joint by joint after heat-melting butt-joint, and caliber substantially diminishes at butt joint, leads
The overall resistance at butt joint of pipeline is caused substantially to increase；And often to be used during use and to electric boiling plate make its hot melt,
It is very inconvenient in some remote place constructions.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fast, easily PE straight tubes special pipe fitting.
A kind of to solve the above problems, PE straight tubes special pipe fitting described in the utility model, it is characterised in that：The pipe fitting bag
Include the main pipe body of interpolation tubing and be socketed in the holding card of the tubing and the main pipe body joint；The main pipe body
Contain a branched steel annulus on the inside of termination, the inside of the steel annulus is provided with groove I；It is provided with the groove I O-shaped
Sealing ring；Groove II is provided with the outside of the termination of the main pipe body, the groove II is located at the tubing and the main pipe body phase
Meet place；The outboard end inwall of the holding card is provided with three layers of reversed acanthoids projection arranged side by side, and the reversed acanthoid is raised with being located at the holding card
Internal semicircular ring is connected；The semicircular ring is provided with groove III, and the groove III matches with the groove II；In the holding card
Provided with bolt, the bolt links together the holding card and the main pipe body.
Length between the groove II at the main pipe body both ends is 2 times of the diameter of the tubing.
The holding card is socketed in the groove II of the tubing and the main pipe body joint, and passes through the spiral shell
Bolt links together the holding card and the main pipe body.
The utility model has advantages below compared with prior art：
1st, the utility model pipe fitting is connected with tubing only needs to complete by bolt, compared to heat-melting butt-joint docking pipe fitting
Speech, both will not cause connector position caliber to diminish suddenly, cause joint resistance to increase, it is not required that hot-melt plate and bonding machine,
Not only install quick, time saving, laborsaving, and its intensity is suitable with body bulk strength.
2nd, there is no flange using the utility model, the tubing termination of connector position, tubing caliber does not change, pipeline
System conveying bore does not diminish suddenly, and the resistance of pipeline liquid will not increase.
3rd, using the utility model, to pipe fitting and tubing connector strength test, the results showed that the performance of pipe fitting completely may be used
To reach relevant criterion requirement.
Result of the test is as follows：
1. load performance is carried out to pipe fitting using the load performance of same specification tubing as index according to GB/T 13663.2-2000
Detection, testing result are crack-free, ne-leakage.
2. according to GB/T 13663-2000 using tensile strength during same specification tubing elongation at break as index, to pipe fitting
Detected with the connector of tubing.Testing result：When reaching the tensile strength of tubing elongation at break, this product and tubing
The connector of composition does not occur slip phenomenon.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1-bolt；2-reversed acanthoid is raised；3-main pipe body；4-O-ring seal；5-holding card；6-tubing；
7-semicircular ring；8-steel annulus.
Embodiment
As shown in figure 1, a kind of PE straight tubes special pipe fitting, the pipe fitting includes the main pipe body 3 of interpolation tubing 6 and is socketed in pipe
Material 6 and the holding card 5 of the joint of main pipe body 3.
Contain a branched steel annulus 8 on the inside of the termination of main pipe body 3, the inside of the steel annulus 8 is provided with recessed
Groove I；O-ring seal 4 is provided with groove I, connector is had stronger intensity and can effectively prevent junction seepage.Main pipe body
Groove II is provided with the outside of 3 termination, the groove II is located at tubing 6 and the joint of main pipe body 3；The outboard end inwall of holding card 5 is set
There are three layers of reversed acanthoid projection 2 arranged side by side, the material of the reversed acanthoid projection 2 is steel material, when effectively preventing from having in pipeline pressure
The slippage of tubing 6.Reversed acanthoid projection 2 is connected with the semicircular ring 7 being located inside holding card 5, i.e.,：Will be convex with reversed acanthoid during injection molding
2 connected semicircular ring 7 injection moldings simultaneously are played, form an entirety.Semicircular ring 7 is provided with groove III, the groove III and groove
II matches；Holding card 5 is provided with bolt 1, and the bolt 1 links together holding card 5 and main pipe body 3.
