Abstract

The utility model provides an aerated pipe stopper, which is composed of an inflating body (1), a hollow pipe (2), an air valve (3) and a blind top (4). The middle of the inflating body (1) is provided with the hollow pipe (2), and the air valve (3) is installed on the inflating body (1). When used, the aerated pipe stopper is put in the pipe, compressed gas is charged from the air valve (3), the inflating body (1) is inflated, and the pipe wall is pressed. Under the function of pressure, the aerated pipe stopper is fast fixed in the pipe, and the pipe blocking and the plugging can be obtained. One end of the hollow pipe (2) is connected with a hose, and the throughflow and erecting a pipe bridge can be conducted. The utility model has the advantages of fast blocking pipe, plugging, convenience, practicality, low cost, good effect, etc.

Description

Aerated pipe stopper

The utility model relates to a kind of Pipe leakage stopper, particularly a kind of Aerated pipe stopper.

The Pipe leakage stopper that generally adopts both at home and abroad has screw plug at present, is called for short plug, and this plug is a machining screw on pipe end, could use then.Plug belongs to a kind of semipermanent pipe plug, has just compared difficulty at pipeline more than 100 millimeters and nonmetal pipeline with plug but work as diameter.Major defect with plug is, when upper and lower conduit damages, and need block the time, it is powerless that plug just seems temporarily! In addition, after at present upper and lower conduit damages, generally adopting the maintenance or adopt and set up the maintenance of steel pipe bridge in addition of cutting off the water night.More than the shortcoming of these two kinds of ways be that the maintenance of cutting off the water night makes troubles for always resident and construction, in addition the maintenance of frame steel pipe bridge not only bothered, cost but also high.

The purpose of this utility model is exactly the above-mentioned shortcoming that exists at prior art, and a kind of Aerated pipe stopper of design.Aerated pipe stopper both can plugging, can set up interim pipe bridge fast again.

A kind of structure of the present utility model is led to type in being, it is made up of expander, middle siphunculus, valve cock, stifle.Middle siphunculus is installed in the middle part of expander, is used to be communicated with two end faces of expander, and valve cock is fixed on the expander, and pressurized gas is just filled into by valve cock and emits.Stifle be in an annex of logical type Aerated pipe stopper, when needs, can block middle siphunculus with stifle.Expander is the open column shape that elastic material is made.One end of middle siphunculus can connect flexible pipe.

Another kind of structure of the present utility model is obstructed type, and it is made up of expander and valve cock.Valve cock is fixed on the expander pressurized gas and is filled into by valve cock and emit.

Fig. 1 be in the structural representation sectional drawing of logical type Aerated pipe stopper

Fig. 2 is the structural representation sectional drawing of obstructed type Aerated pipe stopper

Wherein＜1〉among Fig. 1 is an expander;＜2〉be middle siphunculus;＜3〉be valve cock;＜4〉be stifle;＜5〉among Fig. 2 are expanders;＜6〉be valve cock.

When using in shown in Figure 1 logical type Aerated pipe stopper, earlier it is placed in inlet pipe, charge into pressurized gas by valve cock＜3〉then, make expander＜1〉expansion and give pressure of tube wall, under the effect of pressure, in logical type Aerated pipe stopper just be fixed in the pipe firmly; When also needing medium through-flow, can take off stifle＜4〉when need set up pipe bridge, on middle siphunculus＜2 〉, connect flexible pipe and can realize that leak stopping is through-flow, bridging action.

When using shown in Figure 2 obstructed type Aerated pipe stopper, earlier it is placed in inlet pipe, charge into pressurized gas by valve cock＜6〉then and make expander＜5〉expansion and give pressure of tube wall, under the effect of pressure, obstructed type Aerated pipe stopper just is fixed in the pipe firmly, plays the plugging effect.

The utlity model has quick plugging, leak stopping, convenient and practical, cost is low Effective advantage. Can be widely used in upper and lower conduit, the pipeline maintenance of the industries such as petrochemical industry and interim water supply, are set up pipe bridge etc. at fuel feeding, leak stopping.

Claims
