Description
Technical field
The present invention relates to tubular object extruding fields, more particularly, to a kind of compound channel closure construction method.
Background technique
Tubing is explicitly pointed out in " CECS 315-2012 steel skeleton polyethylene plastic composite pipe pipeline engineering technical regulation "
When the cutting of scene, the end face after cutting should be sealed.The sealing of current compound end surfaces mostly uses greatly hot wind plastic welding mode,
Soldering and sealing tool includes hot air welding gun and miniature extruded type welding gun.However, from practice of construction situation, heat gun or extrusion weldering
The solder up of rifle is all the thermoplastic materials by squeezing out molten condition in the cold wall of tube end face, and this sealing mode is easy to make
At rosin joint, and to there is sealing in this sealing mode time-consuming, seal quality difference and sealing unsightly the problems such as.
Summary of the invention
The present invention is to overcome the inaesthetic defect of sealing described in the above-mentioned prior art, and it is better to provide a kind of sealing effect
Compound channel closure construction method.
In order to solve the above technical problems, technical scheme is as follows:
A kind of compound channel closure construction method, comprising the following steps:
Step 1: in the middle position recessing of composite pipe end face；
Step 2: heating hot plate, it is ensured that hot plate is vertical and corresponding with tube end face；
Step 3: hot plate is promoted, the plastics of groove two sides molten condition are extruded into groove by hot plate；
Step 4: exiting hot plate, after waiting melten gels face is cooling to fix, is carried out by sander to tube end face smooth.
Preferably, step 1 further includes the composite layer cleared up in composite pipe end face and groove, it is ensured that the modeling of groove inner wall
The bed of material retains completely, and composite layer must not have junction with cell wall.
Preferably, in step 1, the depth of composite pipe facing groove is 3-5mm.
Preferably, in step 2, the hot plate side opposite with tube end face is provided with cricoid card slot, the ring of card slot
It is wider than the wall thickness of composite pipe, the internal diameter of cricoid card slot is less than or equal to the internal diameter of tubing, and the outer diameter of cricoid card slot is big
In or equal to tubing outer diameter.
Preferably, in step 2, the heating temperature range of hot plate is 220 ± 10 degree.
Preferably, in step 3, the continuous contact time of hot plate and tubing is 15 ± 2 seconds.
Preferably, in step 4, the outer wall of tube end face and outer pipe wall height are consistent or lower than pipe after planarizing
Within material outer wall height 1mm.
Preferably, groove is U-type groove.
Compared with prior art, the beneficial effect of technical solution of the present invention is: can be completed using primary extruding docking whole
The sealing of a end face effectively improves sealing efficiency, reduces the labor intensity of welding；Void is solved using Double-side Heating mode
Weldering problem；Seal quality is good, good appearance.

Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；
In order to better illustrate this embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent the ruler of actual product
It is very little；
To those skilled in the art, the omitting of some known structures and their instructions in the attached drawings are understandable.
The following further describes the technical solution of the present invention with reference to the accompanying drawings and examples.
Composite pipe in the present embodiment is mainly made of pure PE main body and composite strengthening layer, wherein composite strengthening layer by
High-tensile steel wires or glass are wound enhancing at PE layers.
As shown in Figure 1, being the compound channel closure construction method flow chart of the present embodiment.
Step 1: in composite pipe end face recessing 1.As shown in Fig. 2, for the multiple tube after the recessing of the present embodiment
Material, further groove 1 are U-type groove, and depth is 5mm and width of rebate is uniform, the composite layer in groove 1 is cleaned out, and compound
Layer and the connectionless place of cell wall.
Step 2: heating hot plate 2 to 220 is spent, and ensures that 21 position of hot plate card slot is corresponding and vertical with tube end face.Such as figure
It is the pipe end end face and hot plate of the present embodiment shown in 3.Wherein hot plate 2 selects card slot 21, the ring width of card slot 21 according to tube wall thickness
Need to be greater than the wall thickness of composite pipe, the internal diameter of card slot 21 need to be less than or equal to the internal diameter of tubing, the outer diameter of card slot 21 need to be greater than or
Equal to the outer diameter of tubing.
Step 3: hot plate 2 is promoted, the plastics of the molten condition of groove two sides are extruded into groove 1 by hot plate card slot and are protected
It holds 15 seconds.As shown in figure 4, being the multiple tube seal welding status diagram of the present embodiment, hot plate card slot 21 melts groove two sides
The plastics for melting state are extruded into groove 1, are kept in contact 15 seconds, and sealing is completed.
Step 4: exiting hot plate, waits sealing cooling, and the molten plastic of tube end face two sides is filled into groove 1, makes recessed
1 melten gel of slot is completely covered composite layer and forms melten gel face 3, guarantees composite material in use not by the corruption of pumped (conveying) medium
Erosion.After the completion of melten gel face 3 is cooling, tube end face is polished flat using sander, keeps 3 height of melten gel face with outer pipe wall
Unanimously, wherein melten gel face 3 can be lower than within outer wall 1mm but no more than outer pipe wall.As shown in figure 5, answering for the present embodiment
Close channel closure completion status schematic diagram.
The same or similar label correspond to the same or similar components；
The terms describing the positional relationship in the drawings are only for illustration, should not be understood as the limitation to this patent；
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be to this hair
The restriction of bright embodiment.For those of ordinary skill in the art, it can also do on the basis of the above description
Other various forms of variations or variation out.There is no necessity and possibility to exhaust all the enbodiments.It is all in the present invention
Spirit and principle within made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the claims in the present invention
