Abstract
The utility model relates to a pipeline sealing air bag which comprises a bag body, an air tap communicated with a cavity in the bag body is arranged on the bag body, and a pulling and dragging structure is fixedly arranged in the position adjacent to the air tap on the bag body. When in use of the pipeline sealing air bag, the pipeline sealing air bag is placed in a pipeline and inflated through the air tap. Along with the pressure rise in the air bag, the outer wall of the air bag and the inner wall of the pipeline are tightly jointed together, thereby realizing sealing and cutting off of the pipeline. When the air bag needs to be taken out, deflation is firstly carried out through the air tap, and the air bag is taken out through the pulling and dragging structure after gas release. Therefore, the air bag is adopted for sealing and cutting off the pipeline during a closed water test, thereby not only having high efficiency, but also having low labor intensity. In addition, the air bag can be reused for a plurality of times, thereby eliminating the waste problem and saving the cost.
Description
Technical field
The utility model relates to a kind of seal for pipe joints air bag, particularly a kind of seal for pipe joints air bag of various pipelines being held one's breath, closed water experiment the time carrying out pipeline cut-off.
Background technique
At present, in various pipeline construction processes, closing the water experiment is than indispensable one procedure.In work progress in the past, the sealing means of employing is sealing means such as blind plate welding, steel plate, rubber cushion extruding, to pipeline close water experiment both caused take a lot of work, time-consuming, can cause the waste of material again.
The model utility content
The purpose of this utility model provides a kind of seal for pipe joints air bag, in order to solve the existing problem that occurs taking a lot of work, taking a lot of trouble to reach waste material in the water experiment of closing.
For achieving the above object, the utility model provides following technological scheme: a kind of seal for pipe joints air bag, comprise utricule, and this utricule is provided with the valve that is communicated with the utricule inner cavity, is installed with the pulling structure near the valve position on the utricule.
Described pulling structure comprises a drag-line, and an end of this drag-line is fixedlyed connected with utricule, the other end is connected with a draw ring.
Described utricule is spheroid or spheroid.
When described utricule was spheroid, the axis of valve was parallel with the major axis of spheroid.
Seal for pipe joints air bag of the present utility model puts it in the pipeline in use, by valve it is inflated.Along with the rising of air bag internal air pressure, the outer wall of air bag and the inwall of pipeline fitting together tightly realized that the sealing of pipeline ends.When needs take out air bag, at first exit by valve, treat that gas is emitted after, by pulling structure air bag is taken out.By as seen above-mentioned, the time adopt this air bag to come pipeline sealed to end closing the water experiment, efficient height not only, and also labor intensity is low.In addition, this air bag can repeat repeatedly to use, and therefore the problem that also can not occur wasting provides cost savings.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is that the utility model is arranged at the user mode structural representation in the pipeline.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
Embodiment 1
As shown in Figure 1, the embodiment of the utility model seal for pipe joints air bag comprises a rubber-like utricule 1, is set with a valve 4 on the utricule 1, and the cavity in valve 4 and the utricule 1 is connected.By this valve 4 come to utricule 1 fill, bleed air operation.Go out to be fixedly connected with a drag-line 2 in the position near valve, drag-line 2 is connected with a draw ring 3 away from an end of utricule, and it is to be convenient to the operator this seal for pipe joints air bag is taken out in pipeline 5 that draw ring is set.What utricule adopted in this embodiment is sphere structure.Certainly, utricule also can adopt the structure of spheroid, and when utricule was the spheroid structure, the axis of valve paralleled with the axis of spheroid major axis.This be because, when utricule is spheroid, when being installed into it in pipeline, have only the major axis of spheroid and the parallel axes relatively good installation of ability and the good sealing effect of pipeline, at this moment, have only the axis of valve to parallel just to be convenient to the axis of spheroid major axis to air bag fill, bleed air operation.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
