Abstract

The utility model relates to a pipeline maintenance device, in particular to a plugging device. The plugging device comprises a t-branch pipe, wherein the t-branch pipe comprises a main pipe and branch pipes communicated with the main pipe; a sealing pad is arranged on the inner wall of the main pipe; one end of the main pipe is fixedly provided with a plugging flange through threads; the main pipe is internally provided with a plugging rod penetrating through the plugging flange; the outer surface of the plugging rod is provided with a thread; the plugging rod is connected with the plugging flange through the thread; one end of the plugging rod is located inside the main pipe; the other end of the plugging rod is located outside the main pipe; a plugging block is arranged at one end, inside the main pipe, of the plugging rod; the side wall of the plugging block abuts against the sealing pad. As the sealing pad is arranged on the inner wall of the main pipe and the plugging block abuts against the sealing pad, the sealing effect is achieved.

Description

A kind of blocking device
Technical field
The utility model relates to a kind of pipeline maintenance device, relates in particular to a kind of blocking device.
Background technique
In the construction of modern city, blocking device especially plugging device is more and more applied to the shutoff of under ground piping, neither a nothing the matter at the opening of three-way pipeline and will make capping cover, if sealing cover can not well cover the opening at three-way pipeline, the airtight quality that can affect sealing cover, also can exert an adverse impact to follow-up operation; How sealing cover is well combined with the opening of three-way pipeline and just becomes a difficult problem.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of blocking device, simple in structure, and can regulate as required shutoff situation.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of blocking device, comprise three-way pipe, described three-way pipe comprises main pipeline and is communicated with the branch pipe(tube) of main pipeline, the inwall of described main pipeline is provided with sealing gasket, one end of described main pipeline is fixed with shutoff flange by screw thread, in main pipeline, be provided with the shutoff bar through described shutoff flange, described shutoff rod outer surface is provided with screw thread, described shutoff bar is connected with described shutoff flange by screw thread, one end of described shutoff bar is positioned at main pipeline, the other end of described shutoff bar is positioned at outside main pipeline, one end that described shutoff bar is positioned at main pipeline is provided with plugging block, the sidewall of described plugging block and described sealing gasket butt.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described plugging block is the cubic bodily form.
Further, one end that described shutoff bar is positioned at outside main pipeline is provided with adjustment handle.
Further, described sealing gasket adopts rubber to make.
The beneficial effects of the utility model are: the utility model adopts and establish sealing gasket on main pipeline inwall, by the butt of plugging block and described sealing gasket, reach the effect of sealing, thereby can also regulate as required seal bar to regulate the position of sealing block in main pipeline, when sealing block is adjusted to the upper end at arm road junction in main pipeline, fluid can flow out from arm, when sealing block is adjusted to the lower end at arm road junction in main pipeline, whole three-way pipe is all sealed, and fluid can not flow out.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of blocking device of the utility model.
In accompanying drawing, the list of parts of each label representative is as follows:
1, main pipeline, 2, branch pipe(tube), 3, sealing gasket, 4, shutoff flange, 5, shutoff bar, 6, plugging block, 7, adjust handle.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, the utility model comprises three-way pipe, described three-way pipe comprises main pipeline 1 and is communicated with the branch pipe(tube) 2 of main pipeline 1, the inwall of described main pipeline 1 is provided with sealing gasket 3, one end of described main pipeline 1 is fixed with shutoff flange 4 by screw thread, in main pipeline 1, be provided with the shutoff bar 5 through described shutoff flange 4, described shutoff bar 5 outer surfaces are provided with screw thread, described shutoff bar 5 is connected with described shutoff flange 4 by screw thread, one end of described shutoff bar 5 is positioned at main pipeline 1, the other end of described shutoff bar 5 is positioned at outside main pipeline 1, one end that described shutoff bar 5 is positioned at main pipeline 1 is provided with plugging block 6, the sidewall of described plugging block 6 and described sealing gasket 3 butts.Described plugging block 6 is the cubic bodily form, and one end that described shutoff bar 5 is positioned at outside main pipeline 1 is provided with adjustment handle 7, and described sealing gasket 3 adopts rubber to make.
The utility model adopts and establish sealing gasket on main pipeline inwall, by the butt of plugging block and described sealing gasket, reach the effect of sealing, thereby can also regulate as required seal bar to regulate the position of sealing block in main pipeline, when sealing block is adjusted to the upper end at arm road junction in main pipeline, fluid can flow out from arm, when sealing block is adjusted to the lower end at arm road junction in main pipeline, whole three-way pipe is all sealed, and fluid can not flow out.
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.
