Abstract
The utility model which belongs to the pipe fitting field relates to an air bag for a pipeline which is used for the construction of the water supply pipeline and the water drainage pipeline. An inflatable bag body can be once formed by the bottom, the bag body, the top, and an air valve arranged on the top through the integral forming of the mould vulcanized rubber; the air valve is matched with an air core and a fastening screw; the circumference on the external wall of the bag body is provided with a plurality of convex grains; the bag body is in circular long cylinder-shaped slightly with a conical surface on the top and the bottom; while in use, the air bag for the pipeline is longer than the pipeline diameter junction surface which needs to be plugged; the plugging performance to the pipeline can be reinforced, and the air bag for the pipeline is convenient to be connected with the pipeline. The utility model which is suitable for the connection and the usage of the pipeline with different diameters has good sealing performance, high intensity, and loner service life; the air bag for the pipeline does not burst, disengage from the bottom, and leak the gas, and the product specification is conducted the serialization.
Description
Technical field
The utility model belongs to the pipe fitting field, relate to a kind ofly give, the working pipeline air bag of drainage pipe.
Background technique
Giving, in the drainage pipe work progress, the a part of pipeline that often needs to finish to constructing tries water flowing, have or not race with inspection, emit, drip, leak part, usually use inflatable shutoff capsule, adopt waste and old inner tube of tyre for motor-vehicle to make because this class capsule, its top, the bottom is bonding forming with circular arc cylindrical shell two-port and circular arc cylindrical shell, and the diameter of circular arc cylindrical shell is subjected to the influence of the inner tube of a tyre self radian very lack of standardization, thereby be difficult to and need the pipe diameter of shutoff to match, in use existing the abutting edge easily leaks gas, pipe plugging is not tight, and influence is to the deficiencies such as detection of pipeline.
At present, though adopt the Integratively formed pipeline air bag of mould vulcanized rubber to solve the problem of bonding gas leakage preferably, it is circular-arc or cylindric that but the rubber utricule of this air bag is generally, circular-arc utricule is in use short and small with the pipe diameter junction plane that needs shutoff, and the air bag plugging strength is low; And cylindric utricule is not easy to and the pipeline attaching, and is impracticable: because structural design unreasonable, so still thoroughly do not solve the imprecise problem of pipe plugging at present.
Summary of the invention
The purpose of this utility model is to provide a kind of good airproof performance, and the intensity height in use combines face length with the pipe diameter that needs shutoff, strengthens the sealing characteristics to pipeline, adopts the Integratively formed pipeline air bag of mould sulfuration.
The technical solution adopted in the utility model: a kind of pipeline air bag, adopt by bottom, utricule, top and the valve cock that is installed in the top that the mould vulcanized rubber is Integratively formed to be inflatable utricule, valve inside and tightening nut have been connected on the valve cock, utricule outer wall circumference is provided with burr, and its utricule is up and down the slightly round long tubular of the conical surface.Utricule is up and down the slightly round long tubular of cambered surface.The conical surface or cambered surface cyst wall are thick than the utricule cyst wall about bottom and top and the utricule that links with it.Bottom and top are the arc plane or bore plane.Burr is annular, spirality, is uniformly-spaced or the unequal interval distribution.
The positive beneficial effect that the utility model had:
1, it is Integratively formed that rubber pneumatic bag and valve cock adopt the mould sulfuration, do not have bonding interface, is difficult for gas leakage;
2, utricule is up and down the round long tubular of the conical surface slightly or cambered surface, is convenient to and the pipeline attaching, and is economical and practical;
3, the rubber pneumatic bag of round long tubular and the pipe diameter junction plane lengthening that needs shutoff are strong to the shutoff of pipeline, good airproof performance;
4, be distributed with burr on the outer wall circumference of the rubber pneumatic bag of round long tubular, help strengthening gasbag ektexine and the mutual friction of inner-walls of duct circumference after the inflation, and play and the closely cooperate effect of attaching of pipeline, further strengthen the sealing characteristics of air bag to pipeline;
5, the top of rubber pneumatic bag, bottom and the utricule conical surface wall that links with it are thicker, and the intensity height is difficult for explosion, takes off at the end during inflation, and working life is longer;
6, size of product seriation, the pipeline attaching that is suitable for different-diameter is used.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment:
Consult shown in Figure 1ly, a kind of pipeline air bag comprises bottom 1, utricule 2, top 3, valve cock 4, locking nut 5, valve inside 6, burr 7 etc.; Its bottom 1, utricule 2, top 3 adopt the rubber materials to make, and utricule 2 is up and down the round long tubular of the conical surface slightly or cambered surface, is convenient to and the pipeline attaching; Bottom 1 and top 3 and the utricule that links with it about in the of 2 the conical surface or cambered surface cyst wall thick than utricule 2 cyst walls, the intensity height can explosion during inflation, take off at the end; Bottom 1 and top 3 are the arc plane or bore plane.
It is inflatable sealing utricule that described bottom 1, utricule 2, top 3 and the valve cock 4 that is installed in top 3 adopt the mould vulcanized rubber Integratively formed, no bonding, air tight, sulfuration has several burr 7 simultaneously on utricule 2 outer wall circumference, help strengthening utricule 2 outer walls and the mutual friction of inner-walls of duct circumference after the inflation, with the pipeline attaching that closely cooperates, burr 7 can be annular, spirality, uniformly-spaced or unequal interval distribute; Connect valve inside 6 and tightening nut 5 on the valve cock 4.
Size of product seriation of the present utility model is applicable to the pipeline attaching of different-diameter.
During use the utility model is filled in the water outlet port of pipe under test, then to airbag aeration, the socket that closely cooperates of round long tube position, fully inflated air bag middle part and inner-walls of duct circumference, play plugging action to pipeline, after the detection for the treatment of to try the water in the blocking pipe finishes, bleed off air in the capsule, take out air bag.
