Abstract
This practicality newly discloses a kind of directly buried pipeline leakage detection apparatus, include the air bag piston group for being respectively arranged at detected pipe ends, air bag piston group the inner is connected with traction end, air bag piston group includes outer tube, multiple dividing plates being intervally arranged, air bag are set with outside outer tube, dividing plate, air bag outward flange and detected seal for pipe joints coordinate, and juxtaposed air injection pipe, water injection pipe are provided with outer tube, and air injection pipe is inner to be provided with multiple air injection openings being connected with air bag；The water injection pipe outer end of one of air bag piston group is provided with pressure gauge.The utility model confirms problem by the device simply easily made to solve directly buried pipeline leak source maintenance position, confirms to overhaul position using air bag plus baffle combination device.
Description
Technical field
The utility model belongs to directly buried pipeline Measuring error field, particularly belongs to a kind of directly buried pipeline leakage detection apparatus.
Background technology
After when direct-buried pipe is repaired, it is thus necessary to determine that leak source position is overhauled, and traditional maintenance means are points in the duct
Excavate, pipeline is broken plus dividing plate is divided into two sections, while leak source is checked to the pressurization of two segment pipe water-fillings.If wherein a segment pipe has
Pressure drop, another segment pipe, which then repeats above-mentioned maintenance procedures inspection without pressure drop, pressure drop pipeline section.By that analogy, until finding maintenance
Point.If two segment pipes have pressure drop, both ends pipeline repeats above-mentioned maintenance procedures simultaneously and continued checking for, until finding maintenace point.
Utility model content
The purpose of this utility model is to provide by a kind of directly buried pipeline leakage detection apparatus, and the device simply easily made is straight to solve
Bury Pipeline Leakage Point maintenance position and confirm problem, confirm to overhaul position using air bag plus baffle combination device.
The technical solution of the utility model is as follows：
A kind of directly buried pipeline leakage detection apparatus, include the air bag piston group for being respectively arranged at detected pipe ends, air bag
Piston group the inner is connected with traction end, and air bag piston group includes outer tube, be set with outside outer tube multiple dividing plates being intervally arranged,
Air bag, dividing plate, air bag outward flange and detected seal for pipe joints coordinate, and juxtaposed air injection pipe, water injection pipe, gas injection are provided with outer tube
Pipe is inner to be provided with multiple air injection openings being connected with air bag；The water injection pipe outer end of one of air bag piston group is provided with pressure
Table.
The water injection pipe outer end of described one of air bag piston group is provided with pressure gauge, relief valve by triple valve.
Described traction end has the eave tile being connected with draught line.
The utility model has the advantages that：Baffle combination device is added to be respectively placed in detected pipe ends using two groups of air bags,
Air bag expansion is served as piston after being pressurizeed to airbag aeration, then pressurizeed to two groups of device intermediate conduit water fillings, pass through external pressure
Whether power table depressurizes whether there is leak source to judge to be detected pipeline section.Meanwhile it is tested with after leak source by repeating to draw one end
Device reduces detection length to determine leak source position.Leakage detection apparatus is simple and practical, easily makes, is examined without the means by excavation
Leakage, saves a large amount of maintenance costs.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of directly buried pipeline leakage detection apparatus, include the air bag work for being respectively arranged at the detected both ends of pipeline 1
Plug group 2, the inner of air bag piston group 2 are connected with traction end 3, and air bag piston group 2 includes outer tube 4, is set with outside outer tube 4 multiple
Dividing plate 5, the air bag 6 being intervally arranged, dividing plate 5, the outward flange of air bag 6 and the sealing of detected pipeline 1 coordinate, are provided with simultaneously in outer tube 4
The air injection pipe 7 put, water injection pipe 8, air injection pipe 7 is inner to be provided with multiple air injection openings being connected with air bag 6；One of air bag piston
The outer end of water injection pipe 7 of group 2 is provided with pressure gauge 9, relief valve by triple valve, and traction end 3 has the hook being connected with draught line
Head.
Leakage detection apparatus is placed respectively at the directly buried pipeline both ends to need repairing, after first passing through gas tube to airbag aeration pressurization
Air bag expansion is served as piston, then pressurizeed by water injection pipe to two groups of device intermediate conduit water fillings, be by external pressure gauge
No decompression whether there is leak source to confirm to be detected pipeline section.It is tested with after leak source and reduces detection by repeating one end device of traction
Length determines leak source position.
