Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
One word pipe fitting of a kind of steel-plastic composite pressure pipe, with reference to figure 1 and Fig. 2, including internal layer connecting portion 11 and outer layer
Connecting portion 13, in a tubular form, pipe is internally formed water-guiding hole 111 to internal layer connecting portion 11, and water-guiding hole 111 can convey Jie upon connection
Matter.In a tubular form, outer layer connecting portion 13 is arranged concentrically outer layer connecting portion 13 with internal layer connecting portion 11, and the internal diameter of outer layer connecting portion 13
More than the outside diameter of internal layer connecting portion 11, therefore gap is formed between outer layer connecting portion 13 and internal layer connecting portion 11, gap be equal to
The wall thickness of the PSP steel-plastic composite pressure pipes 18 of one word pipe fitting 1 connection.One end of outer layer connecting portion 13 exceeds internal layer connecting portion
11, other end circumference with internal layer connecting portion 11 forms one after bending inwards.13 bending place of outer layer connecting portion is located at internal layer connection
The side of deviation outer layer connecting portion 13, outer layer connecting portion 13 are two among portion 11, are symmetricly set on internal layer connecting portion 11, shape
Into a word pipe fitting 1, both sides connect identical pipeline in the same way.
For the leakproofness of increase connection, hot-melt adhesive paste face 12 is provided with a word pipe fitting 1, hot-melt adhesive paste face 12 includes
There are interior thermal fusing surface 121 and external hot melting face 122.The PSP steel-plastic composite pressure pipes 18 connected are using steel band rolling formation and carry out
Continuous argon arc butt welding becomes steel pipe 182 and interior composite plastic layer 181, outer composite plastic layer 183 are combined.The modeling of PSP steel is multiple
Combined pressure solenoid 18 has and has higher rigidity and higher intensity than plastic tube, has preferable corrosion resistance than common steel tube.
It is outer compound with PSP steel-plastic composite pressure pipes 18 after 18 and one word pipe fitting of PSP steel-plastic composite pressure pipes, 1 grafting
The face that plastic layer 183 contacts is interior thermal fusing surface 121, the face contacted with the interior composite plastic layer 181 of PSP steel-plastic composite pressure pipes 18
For external hot melting face 122.A word pipe fitting 1 is clipped in after grafting by the electromagnetic coil folder 21 of electromagnetism hot melting equipment 2 to mould again with PSP steel
The outer circumference portion of 18 junction of combined pressure solenoid, is passed through electric current in electromagnetism hot melting equipment 2 presss from both sides 21 to electromagnetic coil, moulds PSP steel
182 layers of fever of steel pipe of composite pressure pipe 18, so as to heat the interior composite plastic layer 181 of PSP steel-plastic composite pressure pipes 18 at the same time
With outer composite plastic layer 183, after the interior thermal fusing surface 121 of a word pipe fitting 1 is heated to external hot melting face 122, molten condition
Plastics engage, and heating time is 20~30 seconds, stops heating, stop heating latter word pipe fitting 1 and PSP steel plastic compount pressures
Solenoid 18 is heated portion of being cooled to an entirety, so that PSP steel-plastic composite pressure pipes 18 are inside and outside with a word pipe fitting 1
Connection, adds the sealing effect of a word pipe fitting 1.
In the junction of outer layer connecting portion 13 and internal layer connecting portion 11, bent inwards by 13 circumference of outer layer connecting portion and form limit
Plane 123, when PSP steel-plastic composite pressure pipes 18 are inserted into the inside of a word pipe fitting 1, PSP steel-plastic composite pressure pipes 18
End face is contradicted with confined planes 123, and the intubating length of a word pipe fitting 1 is subject to confined planes 123 to limit, so the length of insertion
Degree is consistent, it is not necessary to the micro-judgment of people, therefore sealing effect is more preferable during connection, it is reliable to connect.
Annulus force section 14, annular groove force section 15 and ripple force section 16 are provided with one word pipe fitting 1.When human hand acts on
The power on a word pipe fitting 1, when the word pipe fitting 1 is docked with PSP steel-plastic composite pressure pipes 18, the middle finger of hand is embedded into annular groove
Force section 15, forefinger and ripple force section 16, and the first and second finger pulps of forefinger, at the trough of ripple, the finger pulp of thumb is tight
Annulus force section 14 is pressed in, when being acted at the same time at three, improves the comfort of docking, and reduce installation difficulty.
Since respective side is inclined in symmetrically arranged 13 bending place of outer layer connecting portion among internal layer connecting portion 11, so
Two outer layer connecting portions 13 are in the centre position of a word pipe fitting 1 at a distance of setting, about 6 millimeters of distance, so that two outer layers companies
Socket part 13 is formed annular groove force section 15 with internal layer connecting portion 11 in the centre position of a word pipe fitting 1.A word pipe is held to connect
The middle finger finger pulp natural imbedding of hand is into annular groove force section 15 when first 1, so that a word pipe fitting 1 and PSP steel-plastic composite pressure pipes
Finger pulp is applied to the power of a word pipe fitting 1 than the power bigger that only frictionally provides in 18 docking operations.
To avoid finger pulp and the concentration active force of the edges and corners of annular groove force section 15, two sides of annular groove force section 15 are set
Circular conical surface is set to, cone angle is 170 °, and comfort when increase grips, the opening of annular groove is also larger, so that when increasing gripping,
Finger pulp is embedded into the depth of annular groove force section 15.
Ripple force section 16 is provided in the annular groove on 13 outer circumference surface of outer layer connecting portion, and groove depth is 13 wall of outer layer connecting portion
Thick 1/10, two sides of annular groove are corrugated, and are symmetrical arranged, and relatively minimal distance is more than the width of forefinger.Gripped
The first and second finger pulp of forefinger is respectively at two adjacent wave trough positions in journey, in grafting PSP steel-plastic composite pressure pipes 18
During, when insertion while a word pipe fitting 1 is rotated with PSP steel-plastic composite pressure pipes 18, than being easier to grafting.Forefinger
Finger pulp exerts a force the ripple side ascent stage, can rotate a word pipe fitting 1, so as to avoid only armrest and a word pipe fitting 1
The frictional force of outer circumference surface rotated, thus facilitate the installation of PSP steel-plastic composite pressure pipes 18.
Annulus force section 14 is arranged on remote one end combined with internal layer connecting portion 11 of outer layer connecting portion 13, annulus force
Portion 14 is raised for circular ring shape, and thickness is the 1/10 of 13 wall thickness of outer layer connecting portion.When firmly grafting PSP steel-plastic composite pressure pipes 18
During, thumb is parallel with the axis of PSP steel-plastic composite pressure pipes 18, and the finger pulp of thumb presses to the circle of annulus force section 14
On the corner angle that ring convex rise, the thrust that can act on a word pipe fitting 1 is improved.
In order to avoid the circular ring shape protrusion of annulus force section 14 close outside corner angle there is a phenomenon where pressing against hand, in annulus
It is provided with shape protrusion and prevents pressing against hand 17, it is anti-to press against chamfering of the hand 17 for 20 degree of close outside in circular ring shape protrusion, therefore smear
The corner angle in flat outside, prevent during a grafting word pipe fitting 1 presses against hand phenomenon.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability
Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but
As long as all protected in the right of the utility model be subject to Patent Law.
