Description
Technical field
The utility model belongs to technical field of measuring equipment, relates in particular to a kind of device of pipeline pressure test, can carry out comparatively easily the pressure testing of different pipelines.
Background technology
Pipeline pressure test is the tentative work that pipe production, processing enterprise and construction enterprises need to often carry out, and object is the quality that checks pipeline, is mainly the ability that checks anti-interior water (gas) pressure of pipeline.The monitoring equipment using at present, is according to different calibers, uses the fixture of different size to carry out shutoff to pipe ends.Complicated operation, time-consuming length, the fixture manufacturing cost that particularly detects large-diameter pipeline is very high, a set of approximately 80,000 yuan of left and right of matched clamp of diameter 50cm pipeline.Also have the pressure testing equipment that automaticity is high, but price is high, bulky, service condition is harsh.
Summary of the invention
According to the present situation of current pressure testing equipment, especially the detection of large-diameter pipeline is a very large difficult problem, the purpose of this utility model is to provide a kind of easy to operate, pipeline pressure testing device of fast, not needing fixture, reduces the cost of testing equipment, to facilitate the pressure detection of pipeline.The technical solution of the utility model is as follows: a kind of pipeline pressure testing device, be provided with a pair of shutoff core, shutoff core has certain length, one of them shutoff core is provided with water-filling pressurization and chews, and two shutoff cores utilize respectively coupling bolt to be fixed on supporting plate, and supporting plate is provided with footing piece, by footing piece, utilize set bolt to be fixed on chassis, relative two shutoff cores are respectively equipped with flexible cable, and the two ends of flexible cable are located at respectively on strainer, and strainer is fixed on chassis.During use, to be detected pipeline is placed on chassis, shutoff core is inserted into the two ends of detected pipeline, shutoff core is fixed on supporting plate by coupling bolt, coupling bolt adds sealing gasket sealing liquid in shutoff in-core side, supporting plate is fixed on chassis by set bolt and footing piece, the position that is provided with shutoff core in the two ends pipeline of detected pipeline is wrapped with respectively multi-turn flexible cable, in both sides, by strainer, strain, under the pulling force of drag-line, detected pipeline is compressed, be close on shutoff core, under the effect of two ends shutoff core and flexible cable, volume in detected pipeline becomes an airtight space, on the stifled core of a side seal, utilize water-filling pressurization to chew and connect water-filling forcing pipe, by pressing machine, to water-filling in pipeline, pressurize, pipeline is carried out to pressure test.Under the effect of flexible cable, pipeline is radially evenly compressed on shutoff core, thereby has realized the object of sealing.It is worthy of note, this apparatus and method are only effective to the less pipeline of the elastic modulus of pipeline material, inapplicable for the pipeline of the similar materials such as steel pipe, concrete pipe.
The utility model is easy to operate, fast, do not need fixture, reduces the cost of testing equipment, facilitates the pressure detection of pipeline.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure, 1, shutoff core; 2, flexible cable; 3, strainer; 4, chassis; 5, detected pipeline; 6, water-filling pressurization is chewed; 7, supporting plate; 8, coupling bolt; 9, set bolt, 10, footing piece.
embodiment:
With reference to accompanying drawing, the technical solution of the utility model is as follows: a kind of pipeline pressure testing device, be provided with a pair of shutoff core 1, shutoff core 1 has certain length, one of them shutoff core 1 is provided with water-filling pressurization and chews 6, two shutoff cores 1 utilize respectively coupling bolt 8 to be fixed on supporting plate 7, supporting plate 7 is provided with footing piece 10, by footing piece 10, utilize set bolt 9 to be fixed on chassis 4, relative two shutoff cores 1 are respectively equipped with flexible cable 2, the two ends of flexible cable 2 are located at respectively on strainer 3, and strainer 3 is fixed on chassis 4.Described flexible cable 2 is steel wire or wire rope, and described strainer 3 can adopt leading screw.
During use, to be detected pipeline is placed on chassis 4, shutoff core 1 is inserted into the two ends of detected pipeline 5, shutoff core 1 is fixed on supporting plate 7 by coupling bolt 8, coupling bolt 8 adds sealing gasket sealing liquid in shutoff core 1 inner side, supporting plate 7 is fixed on chassis 4 by footing piece 10 and set bolt 9, the position that is provided with shutoff core in the two ends pipeline of detected pipeline 5 is wrapped with respectively multi-turn flexible cable 2, in both sides, by strainer 3, strain, under the pulling force of flexible cable 2, detected pipeline 5 is compressed, be close on shutoff core 1, under the effect of two ends shutoff core 1 and flexible cable 2 and supporting plate 7, volume in detected pipeline 5 becomes an airtight space, on the stifled core 1 of a side seal, utilizing water-filling pressurization to chew 6 connection water-filling forcing pipes is connected with pressing machine, by pressing machine, to water-filling in pipeline, pressurize, pipeline is carried out to pressure test, under the effect of flexible cable, pipeline is radially evenly compressed on shutoff core 1, thereby realized the object of sealing.It is worthy of note, this apparatus and method are only effective to the less pipeline of the elastic modulus of pipeline material, inapplicable for the pipeline of the similar materials such as steel pipe, concrete pipe.
According to the internal diameter of detected pipeline, the shutoff core 1 of processing certain length, the external diameter of shutoff core 1 and the internal diameter of detected pipeline equate or are slightly bigger than normal.The pipeline that diameter is larger can adopt the steel pipe manufacturing that tube wall is thicker, and the adopted round steel that diameter is less is made (also can adopt other materials to make, as long as compressive strength meets the demands).Require the diameter precision machining of shutoff core.Described flexible cable can adopt steel wire.
