First pipeline 10 and second pipeline 20 are connected to the both ends of the pipeline to be measured 100 by S10；

S20 closes first pressure relief element 15, opens second pressure relief element 25, and pass through the first pump control First pump of the control of device 13,12 starting processed, so that first 12 pairs of first pipelines 10 of pump and pipeline to be measured 100 fill stream Body；By 22 starting of the second pump of second pump controller 23 control, so that second pump, 22 pairs of 20 notes of the second pipeline Flowing full body；Close first the 12, second pump 22 of pump and the second pressure relief element 25；

The locator 30 is filled in the pipeline to be measured 100 by S30, controls first pump 12 and second pump 22 Starting, so that fluid injects the pipeline to be measured 100 and pushes the locator 30 to the leak source 110 of the pipeline 100 to be measured It is mobile, when the pressure controller 11 is equal with the pressure data of the pressure detector 21, examined using the detector 40 Survey 110 position of leak source of the pipeline to be measured 100.

In one embodiment, when carrying out detection positioning using the leak source 110 that 110 positioning system of leak source treats test tube road 100, It can water-filling or inflation into pipeline 100 to be measured；By taking water-filling as an example, detecting positioning, specific step is as follows:

1, each pipeline is connected at each quick coupling, and connects instrument power source.

2, the first pressure relief element 15 is closed, the second pressure relief element 25 is opened, sets the bound of pressure controller 11, Adjusting the first pump controller 13 makes the first pump 12 work, while the value for adjusting the second pump controller 23 is 0, stops the second pump 22 It only works, the first pipeline 10 and pipeline to be measured 100 is filled into water, be subject to 3 bubble-free of third hose；The second pump control is adjusted simultaneously Device 23 processed opens the second pump 22, and the second pipeline 20 is made also to fill water；The first pump 12 and the second pump 22 are closed, the second pressure release member is closed Part 25.

3, the first pump 12 is opened, certain pressure is beaten, the first pump 12 is closed, observes pressure controller 11 and pressure detector 21 Change in pressure drop, determining pipeline, there are leak sources 110.

4, lubricant is spread into the painting of locator 30, after sufficient lubrication, pipeline 100 to be measured is filled in from third quick coupling 17 It is interior.It is packaged with positioning chip 33 in locator 30, positioning chip 33 has small in size, and low energy consumption, high reliablity, accurate positioning etc. Advantage.The first pump 12 and the second pump 22 are opened simultaneously, locator 30 moves forward in the presence of hydraulic pressure at this time, automatic running one The section time then proves that locator 30 has automatically achieved leak source 110 when pressure controller 11 is equal with the value of pressure detector 21 Place.

When there are leak hole too small leakage scenarios, pressure controller 11 and pressure detector 21 are watched according to step 4 Pressure data variation, if being put into locator 30 from third quick coupling 17, is put into 30 initial stage of locator, pressure controller 11 Value be higher than pressure detector 21 value.Since leak hole is too small, 30 movement speed of locator is too slow, in order to realize that locator 30 is fast Speed finds leak source 110, needs to observe the digital display value of 11 heel pressure detector 21 of pressure controller, when the value of pressure controller 11 is big In in the value of pressure detector 21, then not up to leak source 110 is proved, at this point, the second pressure relief element of either on or off 25 is primary, continue Observe the value of 11 heel pressure detector 21 of pressure controller.

Such the second pressure relief element of either on or off 25 for several times, until the value of pressure controller 11 is less than pressure detector 21 Value, then prove that leak source 110 is already expired in locator 30, closes the first pump 12 at this time, and opens the second pump 22, and locator 30 is allowed reversely to transport Row, since locator 30 is not up to leak source 110 to inverted running at this time, the value of pressure controller 11 is less than pressure detector 21 Value, the first pressure relief element of either on or off 15 is primary, continues the value for observing 11 heel pressure detector 21 of pressure controller, so beats Switch close the first pressure relief element 15 for several times, until pressure controller 11 value be greater than pressure detector 21 value, then prove to position Device 30 crosses leak source 110 again.Then, it opens simultaneously the first pump 12 and the second pump 22 allows instrument automatic running, until pressure controls The value of device 11 is equal to the value of pressure detector 21, then proves that locator 30 just reaches leak source 110.The position of locator 30 at this time Set the position of namely leak source 110.Then the position of positioning locator 30, that is, positioning chip 33 are found with detector 40 Position, using Precision Orientation Algorithm, is accurately positioned after detector 40 detects the signal of positioning chip 33 in locator 30 33 position of chip.It has determined the position of leak source 110, has opened the first pressure relief element 15 and lay down hydraulic pressure with the second pressure relief element 25, Locator 30 is released, two pumps are finally closed.This positioning device and pipeline 100 to be measured are disconnected, entire implementation process is completed.

Water filling process in above-mentioned localization method can also equally be substituted for gas replenishment process.

The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all Under the design of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or directly/ Other related technical areas are used in indirectly to be included in the scope of patent protection of the utility model.
