Fig. 3 be the utility model B-B to sectional view.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of pipe plugging frock as shown in Figure 1, Figure 2 and Figure 3, comprises that plug 2, guiding plug 2 enter the guide holder 1 of pipeline and for plug 2 provides the cylinder 3 of power, guide holder 1 and cylinder 3 are all positioned on base, make compact structure, and integrated design cost is low.
The second assembly 22 that described plug 2 comprises the first assembly 21, be oppositely arranged with the first assembly 21 and be fixed on the block 5 on the second assembly 22, described the first assembly 21 inside are provided with chamber 23; The cross section of described the second assembly 22 is T shape, the main body of this second assembly 22 be positioned at the first assembly 21 chamber 23 and with chamber 23 relative slidings of the first assembly 21.Described block 5 laterally runs through that the first assembly 21 stretches out and the main body of this block 5 and the second assembly 22 is fixed by screw thread, on described the first assembly 21 block 5 near a side of cylinder 3, have one can be for the interval of block 5 activities.The first assembly 21 coordinates the open annular chamber of formation one with the shoulder of the second assembly 22, be provided with Sealing 4, the second assembly 22 butt seals 4 in this annular chamber, and the seal 4 is made by elasticity retractable material.
Further, described the first assembly 21 stretches out and forms a kink 24 in the one end near the second assembly 22, and the shoulder of this kink 24 and the second assembly 22 forms annular chamber.Such the first assembly 21 is larger with the cross section of Sealing 4, and during compressive seal 4, Sealing 4 is stressed more even, is conducive to the compression of Sealing 4.
Further, described block 5 is 1/5～4/5 of cylinder 3 displacement stroke to the distance of guide holder 1.Within the scope of this compression distance, Sealing 4 expansion effects are better.
Further, described guide holder 1 is U-shaped, is provided with one for locking the lid 6 of pipeline on the top of this guide holder 1.Like this can fixing tube, under the effect of cylinder 3, guarantee that plug 2 enters pipeline.
In use, the pipeline for the treatment of shutoff is placed in to guide holder 1, the interior U-shaped of guide holder 1 is changed accordingly with duct size, and the pipeline mouth of pipe is relative with plug 2; Then use lid 6 fixing tubes on guide holder 1, start cylinder 3 promotion plugs 2 and move in pipeline, due to the effect of block 5, plug 2 is after pipeline motion certain distance, and plug 2 enters in pipeline; Block 5 is stuck with guide holder 1, guide holder 1 stop motion, the second assembly 22 of plug 2 is fixed by screw thread with block 5 again, so the second also stop motion of assembly 22, now the first assembly 21 continues motion under the effect of cylinder 3, thereby compressive seal 4, makes Sealing 4 radial expansion closed conduits, thereby realize internal expansion type sealing.This mode has adopted radially internal expansion type sealing means, and good sealing effect, has saved cost.For special-shaped body, also there is good sealing effect, less demanding to the parallelism of shutoff frock and body end face, reduce assembling difficulty, debug very convenient.
Embodiment: the displacement stroke of cylinder 3 is 100mm, block 5 is 60mm to the distance of guide holder 1 section, and when cylinder 3 promotion plugs 2 enter pipeline, cylinder 3 moving displacements are in 60mm, and plug 2 moves in body; Cylinder 3 moving displacements in the scope of 60mm-100mm, second assembly 22 stop motion under the effect of block 5 of plug 2, cylinder 3 continues to promote the second assembly 22 motion compresses Sealing 4 radial expansions, thereby realizes internal expansion type sealing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
