Abstract

The utility model discloses a tube cover for tube plugging. The tube cover comprises a rubber cover body and a tube hoop hooping the outer side of the rubber cover body. The tube cover further comprises an air tube penetrating through the top end of the rubber cover body and a rubber air ball arranged at the air outlet end of the air tube, and the rubber air ball is located inside the rubber cover body and corresponds to the tube hoop in an inside-to-outside mode. The rubber cover body is made of rubber materials, the external tube hoop tightly hoops a tube opening to achieve the effective sealing effect, the rubber air ball is inflated to be expanded to apply outward pressure to the tube from the interior, the inward fastening force of the tube hoop is accordingly counteracted, the expanded rubber air ball plugs the tube from the interior in advance, and the dual-plugging effect is better.

Description

Pipe lid for pipe plugging

Technical field

The utility model relates to pipe lid for a kind of pipe plugging.

Background technique

The mouth of pipe of buried pipeline is carried out to shutoff, can effectively prevent that toy, foreign material, sewage etc. from entering pipeline, guarantee that pipeline is interior clean, unimpeded, guarantee that pipe-line equipment effectively moves.When prior art is carried out the shutoff of buried pipeline, after construction finishes, by workmen, with plank, plastic board etc., block the mouth of pipe, because this kind of shutoff mode can not be fixed, plank, plastic board etc. are removable, thereby can not effectively prevent that toy, foreign material etc. from entering pipeline, and more do not have seal action, can not stop sewage inlet pipe road.Therefore, need to seek more effective shutoff mode to avoid the appearance of the problems referred to above.

Model utility content

For solving the problems of the technologies described above, the utility model provides pipe lid for a kind of pipe plugging, to realize quick, the efficient shutoff of buried pipeline.

For achieving the above object, the technical solution of the utility model is as follows:

Pipe lid for a kind of pipe plugging, comprises serum cap, and hoop is at the pipe collar in described serum cap outside; Also comprise the tracheae through described serum cap top, and the rubber balloon that is arranged on described tracheae outlet side, it is inner and corresponding with inside and outside described pipe collar that described rubber balloon is positioned at described serum cap.

Preferably, the section of described serum cap is the C type with right angle side.

Pass through technique scheme, when the pipe plugging that the utility model provides covers for pipe plugging with pipe, because serum cap is that rubber material is made, external application pipe collar banding, utilize the elasticity of rubber material, line up has played effective seal action, has fundamentally prevented that animal, foreign material, sewage etc. from entering pipeline; In addition, during for fear of pipe collar banding, cause pipeline compressive deformation, by timely inflation, from inside, corresponding pipe collar applies outside pressure to pipeline to the rubber balloon arranging, thereby offset the inside fastening force of pipe collar, and the rubber balloon expanding has carried out shutoff from inside to pipeline in advance, and double-plugging effect is better.

Accompanying drawing explanation

In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.

Fig. 1 is the sectional structure schematic diagram of pipe lid for the disclosed pipe plugging of embodiment;

Fig. 2 is the sectional structure schematic diagram while managing lid for pipe plugging shown in Fig. 1.

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.

According to Fig. 1, pipe lid for the pipe plugging that the utility model provides, comprises serum cap 12, and hoop is at the pipe collar 11 in serum cap 12 outsides; Also comprise the tracheae 13 through serum cap 12 tops, and the rubber balloon 14 that is arranged on tracheae 13 outlet sides, it is inner and inside and outside corresponding with pipe collar 11 that rubber balloon 14 is positioned at serum cap 12; The section of serum cap 12 be there is right angle side C type to coordinate the end surface shape of pipeline 21.

After construction finishes, while using the utility model shutoff buried pipeline, first serum cap 12 is enclosed within on the mouth of pipe of pipeline 21, then pipe collar 11 is set in to serum cap 12 outsides, with spanner, pipe collar 11 is tightened again, serum cap 12 is being fixed on the mouth of pipe tightly just, thereby played effective seal action.

The utility model is when pipeline 21 shutoff, and because serum cap 12 is made for rubber material, external application pipe collar 11 bandings, utilize the elasticity of rubber material, and line up has played effective seal action, has fundamentally prevented that animal, foreign material, sewage etc. from entering pipeline 21; In addition, during for fear of pipe collar 11 banding, cause pipeline 21 compressive deformations, by timely inflation, from inside, 11 pairs of pipelines 21 of corresponding pipe collar apply outside pressure to the rubber balloon 14 arranging, thereby offset the inside fastening force of pipe collar 11, and the rubber balloon 14 expanding has carried out shutoff from inside to pipeline 21 in advance, and double-plugging effect is better.

To the multiple modification of above-described embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.

Claims

1. a pipe lid for pipe plugging, is characterized in that, comprise serum cap, and hoop is at the pipe collar in described serum cap outside; Also comprise the tracheae through described serum cap top, and the rubber balloon that is arranged on described tracheae outlet side, it is inner and corresponding with inside and outside described pipe collar that described rubber balloon is positioned at described serum cap.

2. pipe lid for pipe plugging according to claim 1, is characterized in that, the section of described serum cap is the C type with right angle side.
