The specific embodiment
Below the utility model is described further.
As shown in Figure 1, two-sided socket joint hot melt die sleeve of the present utility model, comprise pipe die sleeve end 1 and pipe fitting die sleeve end 2, pipe die sleeve end 1 has the ring-type welded seam 13 that is surrounded by molten wall 11 of interior ring and the molten wall 12 of outer shroud, pipe fitting die sleeve end 2 has the two-sided molten wall 21 of ring-type, and its design is that the inner surface at the molten wall 12 of outer shroud offers air discharge duct 14 vertically.When hot melt spigot-and-socket pipe fitting 3 and multiple tube 4 are carried out the hot melt processing, the bell and spigot 33 of pipe fitting 3 is enclosed within on the two-sided molten wall 21 of ring-type of pipe fitting die sleeve end 2, multiple tube 4 ends are inserted in the ring-type welded seam 13 of pipe die sleeve end 1, pipe die sleeve end 1 and pipe fitting die sleeve end 2 obtain heat from heater 5, thereby internal ring wall 32 with pipe fitting 3, (at inwall or outer wall is the multiple tube of metal level in the inside and outside wall fusing of external annulus 31 and multiple tube 4, can reach effect to the metal level heating, guarantee good connection the between metal level and the pipe fitting external annulus), be melted to proper states, with the two respectively from pipe die sleeve end 1, pull up on the pipe fitting die sleeve end 2, exist side by side and be about to the bell and spigot 33 that multiple tube 4 inserts pipe fittings 2, the inside and outside wall of this sampling composite tube internal ring wall 32 can be good and pipe fitting, external annulus 31 fuses together, connect the precision height, and intensity is big, good seal performance.Especially, at the scene during operation, pipe die sleeve end 1 and pipe fitting die sleeve end 2 all are in the state of continuous high temperature, when the bell and spigot 33 with pipe fitting 3 is enclosed within on the two-sided molten wall 21 of ring-type of pipe fitting die sleeve end 2 and multiple tube 4 ends is inserted in the process in the ring-type welded seam 13 of pipe die sleeve end 1, pipe fitting 3 and multiple tube 4 promptly can be melted, can discharge from air discharge duct 14 at the air between pipe fitting 3 and the pipe fitting die sleeve end 2, between multiple tube 4 and the pipe die sleeve end 1, avoid forming the air seal chamber and pipe fitting 3, multiple tube 4 are formed elastic force and influence the hot melt effect.
As the further of technique scheme improved and replenish, can adopt following concrete technical measures:
Pipe die sleeve end 1 and pipe fitting die sleeve end 2 are split-type structural, and pipe die sleeve end 1 and pipe fitting die sleeve end 2 offer connecting hole 15,22 respectively.Connecting hole is used for interconnecting and the two is fixed in heater 5 between pipe die sleeve end and the pipe fitting die sleeve end.
Pipe die sleeve end 1 is for dividing body structure, and its endosome 16 by the molten wall 11 of ring in comprising is formed with the ectosome 19 that comprises the molten wall 12 of outer shroud.Ectosome 19 has the end wall 110 that is positioned at molten wall 12 1 ends of outer shroud, offer pilot hole 111 on this end wall 110, endosome 16 has the assembling shaft part 18 of the corresponding pilot hole 111 in the step 17 that is positioned at molten wall 11 1 ends of ring and this step 17 outsides, and the connecting hole 15 on the pipe die sleeve end 1 is positioned on this assembling shaft part 18.The structure of split like this will be discharged at the air between multiple tube and the pipe die sleeve end when being more conducive to that multiple tube 4 carried out hot melt.
The two-sided molten wall 21 of the ring-type of pipe fitting die sleeve end 2 has external diameter expansion section 23.So that during to pipe fitting 3 fusings the end of bell and spigot 33 is enlarged, convenient with multiple tube 4 insertions, and form a slit between multiple tube and pipe fitting external annulus, this slit can be contained in the molten knurl 41 of piling up in the grafting process, is connected neatly with guaranteeing to strengthen sealing effectiveness.
During concrete the use, as shown in Figure 2, with connector (as bolt, nut, not shown in the figures) pipe die sleeve end 1 and pipe fitting die sleeve end 2 are connected on the heater 5, by heater 5 pipe die sleeve end 1 and pipe fitting die sleeve end 2 are heated to suitable temperature, bell and spigot 33 with pipe fitting 3 is enclosed within on the two-sided molten wall 21 of ring-type of pipe fitting die sleeve end 2 respectively, multiple tube 4 ends are inserted in the ring-type welded seam 13 of pipe die sleeve end 1, to pipe fitting 3, multiple tube 4 is extracted after being melted to appropriate level, can finish connection (as shown in Figure 3) in the bell and spigot 33 with multiple tube 4 insertion pipe fittings 3 immediately, and between multiple tube 4 and pipe fitting 3 external annulus 31, form a slit naturally, this slit holds the molten knurl 41 of piling up in the grafting process, to strengthen sealing effectiveness, guarantee to connect neatly, connect the precision height, intensity is big, good seal performance.Therebetween, in good time sprays the plastics releasing agent to pipe die sleeve end 1 and pipe fitting die sleeve end 2, and preventing that the plastics that melt are attached on pipe die sleeve end and the pipe fitting die sleeve end influences the hot melt effect.
