Description
Technical field
The utility model relates to one and is blocked in various ducted plug, refers more particularly to a kind of plug be blocked in pipe end.
Background technique
At present, the pipeline put is closed for some, especially some are embedded in the plastic pipe of underground, its port all can not block usually, make it in arrangement and long-term put procedure, have foreign matter and enter into this pipeline, have some foreign matters can react with tube wall, shorten the working life of pipeline; And when will formally enable, cleaning of also will taking time, adds user cost.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of can shutoff hermetically at the pipe stopper of pipe end.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of pipe stopper, its structure comprises: cover plate and the stopper matched with inner bore of pipeline arranged on the cover board, stopper is arranged with elastic seal cartridge, the concrete set-up mode of elastic seal cartridge is: described elastic seal cartridge includes annular upper wall and is arranged on the cylindrical sidewall in this annular upper wall, cylindrical sidewall is set on the side of described stopper, annular upper wall is attached on the end face of described stopper, and the rear portion of cylindrical sidewall is provided with several annular convex ribs.
As a kind of preferred version, in described a kind of pipe stopper, if: the inner diameter of pipeline is D, then, described elastic seal cartridge thickness T=K × D+1.2,0.012≤K≤0.017, the height H of annular convex rib is equivalent to 10 ~ 15% of elastic seal cartridge thickness T, and unit is millimeter.
As a kind of preferred version, in described a kind of pipe stopper, the front portion of described stopper is the taper that rear end is large, front end is little, corresponds, and the front portion of described elastic seal cartridge is also in the taper that rear end is large, front end is little.
As a kind of preferred version, in described a kind of pipe stopper, the taper angle of described stopper front portion is equal with the taper angle of described elastic seal cartridge front portion, is all not less than 5 °.
As a kind of preferred version, in described a kind of pipe stopper, described elastic seal cartridge is rubber sealing boot.
The beneficial effects of the utility model are: the utility model, due to the elastic seal cartridge with the rear portion undulate of annular upper wall, cylindrical sidewall sheathed on stopper, makes this pipe stopper can by reliable for corresponding pipe end shutoff; And annular upper wall also reduces cost of material, facilitate installation; In addition, through repeated tests and checking, obtain the empirical correlation of calculating elastic stuffing box gland thickness, the elastic seal cartridge made by this empirical correlation not only can improve the reliability of shutoff further, but also saves cost of material.In addition, taper is arranged in the front portion of stopper and the front portion of elastic seal cartridge, serves good guide function, thus greatly facilitate the installation of described pipe stopper.

Embodiment
Below in conjunction with accompanying drawing 1 to accompanying drawing 5, describe the specific embodiments of a kind of pipe stopper described in the utility model in detail:
As Fig. 1, shown in Fig. 2, a kind of pipe stopper described in the utility model, comprise: cover plate 1 and the stopper 2 matched with inner bore of pipeline be arranged on cover plate 1, as shown in Figure 3 and Figure 4, the front portion of stopper 2 is that rear end is large, the taper that front end is little, its taper angle is not less than 5 °, stopper 2 is arranged with the rubber sealing boot 3 as elastic seal cartridge, the concrete set-up mode of rubber sealing boot 3 is: described rubber sealing boot 3 includes annular upper wall 33 and is arranged on the cylindrical sidewall 30 in this annular upper wall 33, the front portion 31 of the taper that cylindrical sidewall 30 is equal with the taper angle of stopper 2 front portion by taper angle is formed with the corrugated rear portion 32 comprising three annular convex ribs 321---and shown in Figure 5, the number of annular convex rib 321 and span can be determined according to actual conditions, cylindrical sidewall 30 is set on the side of described stopper 2, annular upper wall 33 is attached on the end face of described stopper 2, during practical application, the thickness T of described rubber sealing boot 3 determines according to the inner diameter of wanted blocking pipe and internal diameter D, that is: the thickness T=K × D+1.2 of rubber sealing boot 3,0.012≤K≤0.017, the height H of annular convex rib is equivalent to 10 ~ 15% of rubber sealing boot thickness T, and unit is millimeter.Here is the table of comparisons of the height T of annular convex rib 321 on the thickness of rubber sealing boot 3 on the internal diameter D of four kinds of common pipelines and the plug supporting with corresponding pipeline and rubber sealing boot 3.
| Internal diameter of the pipeline (mm) | The thickness (mm) of rubber sealing boot | The height (mm) of annular convex rib |
| 110 | 2.52～3.07 | 0.252～0.4605 |
| 200 | 3.6～4.6 | 0.36～0.69 |
| 400 | 6.0～8.0 | 0.6～1.2 |
| 600 | 8.4～11.4 | 0.84～1.71 |
During use, the stopper 2 being arranged with rubber sealing boot 3 of above-mentioned pipe stopper is filled among the port of corresponding pipeline.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations done according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
