Description
Technical field
The utility model relates to the processing and manufacturing field of testing equipment, what be specifically related to is a kind of packoff of the pressure pipeline hydraulic testing.
Background technology
Need when carrying out the sealing hydraulic testing to municipal water supply pipeline to carry out encapsulation process to whole piece pipeline, and then carry out the hydraulic testing, and traditional plugging structure is comparatively complicated, directly cause the efficiency of whole testing comparatively low, when detecting especially piecemeal, often even can incur loss through delay the whole duration.
Utility model content
The utility model object is to provide a kind of packoff of the pressure pipeline hydraulic testing, and it can solve problem existing in background technology effectively.
In order to solve the packoff of a kind of pressure pipeline hydraulic testing of problem existing in background technology, it comprises a cylindrical airbag 1 that can be inserted in pipeline, throughly in this air bag 1 be fixed with a pipe 2, one end of described pipe 2 is positioned at pipeline, its other end extends air bag 1 and is connected with threeway 3, the other two ends of described threeway 3 are connected with tensimeter 5 with ball valve 4 respectively, the edge circumference that described air bag 1 extend into one end in pipeline is provided with a circle rubber 6, the periphery of described air bag 1 is provided with the sealing gilled rings 7 of several interval arrangement, one end that described air bag 1 is positioned at pipeline is provided with the valve 8 communicated with its inside.
Owing to have employed above technical scheme, the utility model has following beneficial effect: structure is simple, and sealing effectiveness is desirable, is especially applicable to the hydraulic testing of heavy civil water supply network, the encapsulation process to pipeline can be realized at short notice, improve the efficiency of overall inspection greatly.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment being clearly and completely described.
Referring to Fig. 1, this embodiment is achieved by the following technical solutions, it comprises a cylindrical airbag 1 that can be inserted in pipeline, throughly in this air bag 1 be fixed with a pipe 2, one end of described pipe 2 is positioned at pipeline, its other end extends air bag 1 and is connected with threeway 3, the other two ends of described threeway 3 are connected with tensimeter 5 with ball valve 4 respectively, the edge circumference that described air bag 1 extend into one end in pipeline is provided with a circle rubber 6, the periphery of described air bag 1 is provided with the sealing gilled rings 7 of several interval arrangement, the inwall that this gilled rings 7 can guarantee its pipeline that can effectively fit has stopped the generation of water leakage situation, one end that described air bag 1 is positioned at pipeline is provided with the valve 8 communicated with its inside.
Below in conjunction with accompanying drawing, the using method of technical scheme part in this concrete enforcement and principle thereof are further elaborated:
First the air bag 1 of packoff is inserted in pipeline, and check that whether the inside of pipeline is smooth, then the tracheae of supercharging device is connected with valve 8, and by supercharging device toward inflation in air bag 1, the position of air bag 1 is constantly adjusted in the process that air bag 1 expands, make it be fitted in closely all the time on the inwall of pipeline, after having inflated, the hydraulic testing of being correlated with can be carried out.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
