Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical solution of the utility model is described further.
A kind of sealing device for direct-buried pipe foam process, including bottom plate 1, bracket 11, disk 2, claw 21, blanket gas
Cylinder 26, sealing sliding sleeve 27, sealing guide rod 28, sealing flange 3 and sealing ring 32,
The end face of the disk 2 is equipped with claw 21,
The bottom plate 1 is placed on ground, and bracket 11 is set on bottom plate 1, and sealing cylinder 26 and sealing sliding sleeve 27 are installed
In on bracket 11, the rod end of the sealing cylinder 26 is connect with 2 end face of disk, and the sealing guide rod 28 is slided with sealing sliding sleeve 27
One end of connection, the sealing guide rod 28 is connect with disk 2,
The sealing flange 3 opens up annular groove 31, and the sealing ring 32 of rubber material is annular, has a closed sky
Chamber is provided with the gas nozzle 321 being connected with closed cavity on sealing ring 32, and sealing ring 32 is installed in groove 31, the sealing
Flange 3 is clamped by claw 21.
As shown in Figure 1, the direct-buried pipe 8 with foaming processing is placed on liftable pedestal, due to for bilateral symmetry,
Left side part is shown only in figure, disk 2 is vertically arranged, and is pushed it to move left and right by sealing cylinder 26, will be held on claw
Sealing flange 3 on 21 pushes direct-buried pipe 8 to, by the end part seal of direct-buried pipe 8.
As shown in figure 4, usually there is no gas inside the airtight cavity of sealing ring 32 under state, huddling up in groove 31
Inside, at this point, sealing flange 3 is during in direct-buried pipe 8 to push back dynamic, sealing ring 32 and the outer wall of direct-buried pipe 8 are not squeezed
Press contacts can effectively prevent the case where sealing ring 32 damages in sliding process in sealing flange 3.
