Abstract

The utility model discloses an air-bag-type pipeline plugging device which comprises a sealing disk and inflatable sealing elements. Grooves are formed in the peripheral surface of the sealing disk. The inflatable sealing elements are inlaid into the grooves, and air taps which are used for air inflation/deflation are arranged on the inflatable sealing elements. The air-bag-type pipeline plugging device is low in cost, simple in manufacturing process and convenient to use. When inflation deformation is carried out on sealing rings, large friction force is produced between the air-bag-type pipeline plugging device and a pipe wall, and a plugging effect is achieved. The air-bag-type pipeline plugging device is provided with a dedicated anti-theft device, is good in anti-theft effect, and can be recycled, and has good social benefit and economic benefit.

Description

Air sac type pipe plugging device
Technical field
The utility model relates to a kind of pipe plugging device, and particularly a kind of air sac type pipe plugging device specifically can be used for the interim shutoff of long conveyance conduit construction.
Background technique
China's pipe-line construction has entered climax stage, the caliber size of laying has nothing in common with each other, and landform and the weather of construction become increasingly complex, particularly in the construction of the southern network of rivers and northern seasonal Large River Crossing pipeline construction, according to pipeline construction technology, characteristics and demand, need many places to let the hair grow.When letting the hair grow a little on ditch, pipeline can't guarantee to manage interior cleaning as shutoff in time; And in ditch following time, the blind plate at place is lost if pipeline is let the hair grow, and pipeline " bowel lavage " accident very easily takes place, and artificial pigging is very risky, also very easily causes equipment such as block valve poorly sealed, moves for pipeline from now on and buries accident potential.Interim blind plate in use, need multiple welding and dismounting (operations such as each pipeline section welding is finished, head, non-destructive inspection, pressure testing all need to use interim blind plate), welding equipment and welder repeatedly long distance dispatch, and time-consuming taking a lot of work influences normal flowing water construction operation.
The model utility content
In view of the problems referred to above that prior art exists, it is a kind of easy to use and have antitheft and air sac type pipe plugging device water-proof function that the purpose of this utility model is to provide.
To achieve these goals, a kind of air sac type pipe plugging device of the present utility model comprises seal disc and inflatable seal, and the outer edge surface of described seal disc is provided with groove; Described inflatable seal is embedded in the described groove and described inflatable seal is provided with valve for inflation/deflation.
As preferably, described seal disc comprises by a steel ring and a sealing plate and constituting that described groove is arranged on the outer edge surface of described steel ring.
As preferably, described sealing plate the plate face be provided with a perforate, described valve is over against described perforate.
As preferably, described perforate is by locking framework sealing.
As preferably, described locking framework comprises the set screw nut that seals described perforate and is arranged at protecting sheet around the described set screw nut.
As preferably, described inflatable seal is annular.
As preferably, described inflatable seal is the rubber material.
Than prior art, the utlity model has following beneficial effect:
1. air sac type pipe plugging device of the present utility model has stronger water proofing property.Utilize flexible good material to make seal ring, realize sealing in the pipe by seal ring inflation distortion, prevent in the sewage inlet pipe that sealing material adopts rubber material.
2. air sac type pipe plugging device of the present utility model has rock-steady structure.Applied structure can effectively be controlled the distortion with fixing seals.
3, air sac type pipe plugging device of the present utility model is easy and simple to handle.This plugging device structure is light, and an on-the-spot people just can finish.
4. air sac type pipe plugging device anti-theft rate height of the present utility model has anti-theft device, has only the special tool of use to open.The stolen rate of this plugging device is no more than 2 ‰ theoretically, can effectively reduce the cost that pipeline " bowel lavage " accident takes place.

Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 6, an embodiment at air sac type pipe plugging device of the present utility model comprises seal disc 2 and inflatable seal 1, and described seal disc 2 is circular, and its outer edge surface is provided with groove 21; Described inflatable seal 1 is embedded in the described groove 21 and described inflatable seal 1 is provided with valve 11 for inflation/deflation.
In the utility model, as shown in Figure 6, described seal disc 2 also can be to be made of a steel ring 23 and a sealing plate 24, and is arranged at the outer edge surface of described steel ring 23 as mentioned above for the groove 21 of ccontaining inflatable seal 1.
The using method of air sac type pipe plugging device of the present utility model is as follows: air sac type pipe plugging device manually is positioned over about 1 meter in the mouth of pipe, charger connects the valve 11 of inflatable seal 1, give inflatable seal 1 inflation, inflatable seal 1 tensioner is sticked in inner-walls of duct, reach the purpose of shutoff.Preferably, as shown in Figure 5 and Figure 6, plate face that can described sealing plate 24 is provided with the general 50mm of perforate 22(size), the size of perforate 22 so that the joint of charger by being advisable.Make the general 70mm of described valve 11(length then) over against described perforate 22.Further again, in order to reach antitheft purpose, as preferably, as shown in Figure 1, as preferably, described valve 11 is by locking framework sealing.After the locking framework sealing perforate 22, can prevent unrelated person dismounting air sac type pipe plugging device, reach antitheft purpose.In addition, as Fig. 6, Fig. 7 and shown in Figure 8, locking framework can be set at particularly and comprise the set screw nut 3 that seals described perforate 22 and be arranged at protecting sheet 25 around the described set screw nut.Need adopt isolated plant to remove set screw nut 3 when removing like this, air in the inflatable seal 1 put got final product again, this structure is light, and site operation one people just can finish and pacify the work of tearing open.
For inflatable seal 1, its role is to be embedded in the outer rim of seal disc 2 and by inflation and play seal action, therefore as shown in Figure 2, described inflatable seal 1 is preferably an annular.But other shapes, for example the inflatable part of a plurality of strips or arcuation should also can reach requirement.Described inflatable seal 1 general the employing has high elasticity, high frictional property material, in the present embodiment, preferably adopts the rubber material.
As from the foregoing, the utility model cost is low, and manufacturing process is simple, and is easy to use.Utilize fixing ring 1 inflation distortion, itself and tube wall produce big frictional force and play plugging action, have special-purpose anti-theft device, and anti-theft effect is good, can reuse, and has good society and economic benefit.
Above embodiment is exemplary embodiment of the present utility model only, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in essence of the present utility model and protection domain, this modification or be equal to replacement and also should be considered as dropping in the protection domain of the present utility model.
