Abstract
The invention relates to a pipe connecting method. The connecting method comprises the following steps: firstly, a joint of a connected pipe is extruded with a connecting part by a hydraulic channeling machine; the radius of the connecting part is smaller than the radius of the connected pipe; then, one side near the connecting part and far from the joint is extruded with a groove by the hydraulic channeling machine; the ends of the connecting part of the connected pipe are in butt joint, and the connecting ports are polished flatly; the connecting ports are prefixed by sealing strips; then, a hoop rubber ring is positioned on the outer side of the connected pipe, and is matched with the prerolled groove; a hoop is buckled at the external of the hoop rubber ring; and finally, a bolt is used for fastening. The pipe connecting method is excellent in connection sealing performance, can convey a medium with high seepage force, is more convenient for construction, is more reliable in connection, and is convenient for installation, disassembly and maintenance.
Description
Technical field
The present invention relates to fluid pipeline conveying technology field, particularly to a kind of pipe connecting method.
Background technology
In industrial oil（As diesel oil, kerosene, gasoline, hydraulic oil and lubricating oil etc.）During long distance delivery, all can meet
The problem connecting to pipeline, is connected by screw thread or soldering connection between existing pipeline, and memory pipeline connects；Screw thread is even
Connect the duct wall being related to thicker, and easy appearance loosens phenomenon；And although soldering connection has the characteristics that high intensity and low cost,
But also require that connected pipe has certain wall thickness in engineering site construction；The pipeline voltage endurance capability of memory pipeline connected mode is simultaneously
Not high, it is simultaneously connected with intensity to the fit-up gap very allergy between memory internal diameter of pipe joint and connected tube outer diameter, actual
Because machining accuracy is limited in engineering, the fluctuation of fit-up gap size certainly exists, and so leads to installation guard system respectively to connect
The voltage endurance capability height meeting place is uneven, then construction quality is difficult to ensure that；Groove is connected to become the widely used pipe of people in recent years
One of road connected mode, but when the medium osmosis power of pipeline is stronger, such as diesel oil, traditional groove type clip connecting pipe
Reliability just very low, easily its sealing effectiveness is poor, the phenomenons such as seepage, de- pipe easily, can not meet use requirement.
Content of the invention
The present invention is aiming at the problems referred to above, provide a kind of connection sealing can good, penetration can be conveyed by strong Jie
Matter, constructs more convenient simultaneously, connects more structurally sound pipe connecting method, but also is easily installed, dismantles and keeps in repair.
For achieving the above object, the present invention adopts the following technical scheme that：A kind of pipe connecting method, described method of attachment bag
Include following steps：
A. first the joint of connected pipe is squeezed out a connecting portion using hydraulic channeling machine, the radius of described connecting portion is less than
The radius of connected pipe；
B. and then being close to the side away from joint for the connecting portion one groove is squeezed out using hydraulic channeling machine；
C. the connecting portion end of connected pipe is docked, seam is polishing to smooth；
D. in seam, pre-fixed using sealing strip；
E. then it is placed in the outside of connected pipe using clip cushion rubber, and match with the groove of rolling in advance；
F. buckle clip in the outside of clip cushion rubber again；
G. finally fastened with bolt.
The thickness sum of the radius of described connecting portion and described sealing strip is equal to the radius of connected pipe.
The quantity of described groove is two.
In described step e, described clip cushion rubber reverse side first is enclosed within connected pipe, waits to dock, adopts described sealing
After bar is pre-fixed, then carry out folded over, clip cushion rubber is ploughed under in described groove.
In described step g, described bolt in fastener cycle, fastening to be balanced.
The beneficial effects of the present invention is：
A kind of connection sealing energy is good, can convey penetration by strong medium by providing for the present invention, constructs more square simultaneously
Just, connect more structurally sound pipe connecting method, but also be easily installed, dismantle and keep in repair.
Brief description

Fig. 2 is the structural representation of clip cushion rubber of the present invention.
Fig. 3 is yoke configurations schematic diagram of the present invention.
Wherein：1st, connected pipe 2, connecting portion 3, groove 4, sealing strip 5, clip cushion rubber 6, clip 7, bolt.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
A kind of pipe connecting method as shown in Figure 1, Figure 2, Figure 3 shows, described method of attachment comprises the following steps：
First the joint of connected pipe 1 is squeezed out a connecting portion 2 using hydraulic channeling machine, the radius of described connecting portion 2 is little
Radius in connected pipe 1；Using hydraulic channeling machine, connected pipe 1 is rolled according to pre-set thickness,
Roll out connecting portion 2, if rolling mouth is jagged, application wheel machine polishes smooth；
Then one groove 3 is squeezed out using hydraulic channeling machine being close to the side away from joint for the connecting portion 2, described groove 3
Quantity can be two, and the quantity of groove 3 is adapted with the structure of clip cushion rubber 5, if clip cushion rubber 5 adopts one layer of bundle to close, will
The quantity of groove 3 is set to one, if clip cushion rubber 5 adopts two layers of bundle to close, the quantity of groove 3 is set to two；Equally, ditch
If rooved face is jagged, application wheel machine polishes smooth；
By the docking of connecting portion 2 end of connected pipe 1, seam adopts abrasive machine polishing so that two connected pipe 1 interfaces
Smooth, in order to be reliably connected；
In seam, pre-fixed using sealing strip 4, for better seal, can by the width of sealing strip 4 be set to
Length between two connecting portions 2 is consistent；And the thickness sum of the radius of described connecting portion 2 and described sealing strip 4 is equal to quilt
The radius of connecting pipe 1 is so that the seam of two connected pipes 2 is connected firmly and attractive in appearance；Additionally, described sealing strip 4 exists
During sealing joint, first can coat a layer of adhesive, be easy to seal；Described sealing strip 4 is quality of rubber materials, and corrosion-resistant；
Then it is placed in the outside of connected pipe 1 using clip cushion rubber 5, and match with the groove 3 of rolling in advance；Described clip
Cushion rubber 5 reverse side first is enclosed within connected pipe 1, after docking, being pre-fixed using described sealing strip 4, then carries out folded over,
Clip cushion rubber 5 is ploughed under in described groove 3, reliable bundle closes.
Clip 6 is buckled in outside in clip cushion rubber 5 again, in order to the later stage dismounting, easy to maintenance, described clip 6 be two right
The semicircle ring structure claiming, in buckle hoop 6, first half is buckled on clip cushion rubber 5, then fastens other half, then in card
Hoop 6 both sides bolt 7 fasten, described bolt 7 in fastener cycle, fastening to be balanced, first two bolts 7 are fixed on card
On hoop 6, first twist one of bolt 7 one circle, still further a bolt one encloses, and so circulates, is reliably connected to reach.
Due to present invention employs the double sealing structure of sealing strip and clip cushion rubber, and clip fixed structure so that
Pipeline has good sealing, and increasing with liquid in pipe pressure, and its sealing also accordingly strengthens；Construct more simultaneously
Convenient, it is easily installed, dismantle and keep in repair.
Above one embodiment of the present of invention is described in detail, but described content has been only the preferable enforcement of the present invention
Example is it is impossible to be considered the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement
Deng all should still belong within the patent covering scope of the present invention.
