Abstract
The invention discloses an on-line leak detection device for a drainage system pipeline. The on-line leak detection device comprises a leak detection device body, wherein the leak detection device body comprises a four-way valve, an air tube, a pressure gage, a pressurizing air bag and a sealed air bag, wherein the two ends of the air tube are respectively connected with a first port of the four-way valve and the sealed air bag; an air inlet and an air outlet are respectively formed in the two ends of the pressurizing air bag; the air outlet of the pressurizing air bag is connected with a second port of the four-way valve; an air inlet one-way valve is mounted at the air inlet of the pressurizing air bag; the pressure gage is mounted at a third port of the four-way valve; an air discharge switch is mounted at a fourth port of the four-way valve. Through the adoption of the structure, the on-line leak detection device for the drainage system pipeline, provided by the invention, is simple in structure and convenient to operate, and can greatly reduce the leak detection cost and effectively improve the leak detection efficiency.
Description
Technical field
The present invention relates to a kind of online leakage detection apparatus that can detect online drainage system pipe seepy question.
Background technology
Because the pipe end of drainage system pipe is mostly narrow, and the length of pipeline is conventionally longer, the connection of drainage system pipe is also intricate simultaneously, and still pre-buried installation mostly, once there is drainage in drainage system pipe therefore, people often demand help professional leak detection personnel to hunt leak to search, not only spend cost high, and inefficiency.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of simple in structure, easy to operate, can significantly reduce leak detection cost and effectively improve the online leakage detection apparatus of drainage system pipe of leak detection efficiency.
For achieving the above object, the invention provides a kind of online leakage detection apparatus of drainage system pipe, comprise leakage detection apparatus body, described leakage detection apparatus body includes four-way valve, tracheae, tensimeter, pressurised airbag and pressure bladder, the two ends of described tracheae are connected with pressure bladder with the first interface of four-way valve respectively, the two ends of described pressurised airbag form respectively air intake opening and gas outlet, the gas outlet of described pressurised airbag is connected with the second interface of four-way valve, on the air intake opening of described pressurised airbag, breather check valve is housed, described tensimeter is loaded on the 3rd interface of four-way valve, on the 4th interface of described four-way valve, air discharge cook is housed.
The invention has the beneficial effects as follows: adopt said structure, during detection, people first penetrate the pressure bladder of also unaerated from one end of pipe under test, and extend to the other end of pipe under test, by pressing pressurised airbag, make pressure bladder inflation again, until the other end of pipe under test is sealed up, then in pipe under test, fill water, by observing this segment pipe, whether seepage just can judge whether this segment pipe exists seepy question, one-piece construction is simple, easy to operate, can significantly reduce leak detection cost and effectively improve leak detection efficiency, and because of four-way valve this part with pressure bladder between be to be connected by tracheae, therefore no matter how intricate pipe under test is, leakage detection apparatus body provided by the present invention can be suitable for.Meanwhile, on the 3rd interface due to described four-way valve, tensimeter is also housed, so people can change by the manometric reading of Real Time Observation to pressure bladder when inflation pressurization, thereby making the pressurization inflation of pressure bladder more safe and reliable.Separately, on the 4th interface due to described four-way valve, air discharge cook is also housed, therefore, after detecting, can opens air discharge cook exhaust, thereby the exhaust of being convenient to after pressure bladder detects is taken out.
The present invention can further be set to described breather check valve and comprise inlet suction port, and in described inlet suction port, correspondence is equipped with for controlling the steel ball of inlet suction port one-way air inlet.
The present invention can further be set to be provided with O-ring seal between the gas outlet of described pressurised airbag and the second interface of four-way valve, between the first interface of described tracheae and four-way valve and between described tracheae and pressure bladder, all by hermetic seal joint, is connected.Adopt above-mentioned setting, can further promote the whole impermeability of leakage detection apparatus body.
The present invention can further be set to described air discharge cook for can be set in the U-shaped cover on described four-way valve the 4th interface, and on the inner bottom surface of described U-shaped cover, be also provided with the projection that can insert in described four-way valve the 4th interface, on the outside surface of described U-shaped cover, be evenly equipped with pivoting friction lines.
