Principle of operation

Take a water leakage detector with the model number of KLD-801 as an example:

1. understanding the scene

The water leakage detector picks up the water leakage sound, converts the water leakage sound into an electric signal, amplifies the electric signal by the amplification module, transmits the electric signal to the earphone 4 through digital filtering processing of the filtering module, and judges the accurate position of a water leakage point through processing of the microprocessor, however, if the water does not overflow under pressure, the noise does not pass through a sewer pipe which is transmitted to two sides by a pipeline or the water leakage condition caused by rainwater and underground water, the water leakage detector cannot accurately detect whether the water leakage occurs, and therefore, when the water leakage occurs, the phenomenon is required to be confirmed to be originated from the pipeline or other factors.

2. Selection of conduits

When confirming that the water leakage belongs to the pipeline, firstly, the specific pipeline with the water leakage is confirmed, for example, one of a warm air pipeline, a hot water pipeline or a cold water pipeline is selected and pressed indoors, and then the other pipeline is confirmed.

3. Selection of sensors

First, the environment surrounding the location of the water leak detector is carefully observed and the detection operator determines the need to use a sensor that can quickly detect the location of the target. The hand-held sensor 6 can be selected for use in a narrow environment indoors and an environment requiring higher accuracy, while the multifunction sensor 7 is mainly used outdoors.

4. Detection pipeline

Before detection, the pipeline needs to be pressurized, and then a sensor is used for detecting along the pipeline to finally determine the accurate position of the water leakage point.

5. Preparation work

Firstly, the earphone 4 is inserted into an earphone hole of the detector host machine 2, one end of the connecting cable is inserted into the probe hole, the other end of the connecting cable is connected with the sensor, and if the pipeline leaks water, the pipeline needs to be pressurized firstly and then works.

6. Start of detection

The water leakage symptom is grasped, firstly, the handheld sensor 6 is used for further reducing the interval where water leakage is possible before detection, and the sound listening rod 5 can be used for confirming the water dripping sound through a manhole, an externally exposed pipeline, a valve or a water tap.

7. Finding precise position

1) Indoor accurate detection

The position of finding slight water leakage point through handheld sensor 6 can be accurate, through the removal of pipeline every 30 centimeters to the direction of the sound of leaking is moved and is look for to the great direction of sound of leaking, indoor leaking is mainly with slight leaking, consequently need utilize air compressor to pressurize and detect, if the large tracts of land crosstalk equipment explodes the table and can not accurate location, can utilize the relief pressure valve to reduce the intraductal pressure, reduce the sound that the pipeline sent, can accurate location.

2) Outdoor accurate detection

The multifunctional sensor 7 mainly detects the outdoor dew phenomenon of fire fighting pipelines, tap water pipelines, heating pipelines and the like, moves forwards at an interval of 50 cm-1 m from the top of a drainage pipeline, searches for the specific position of a water leakage sound, determines the accurate position of the pipeline to effectively detect the water leakage, judges the size of the water leakage sound according to the specified moving interval, and makes the sound larger when the pipeline is closer to a water leakage valve and the sound larger when the pipeline is closer to the water leakage ground.

8. Water leakage sound judgment

Depending on the location of the rupture, the direction of the rupture, the diameter of the pipe, and the material of the floor, different sounds of water leakage may be generated. Therefore, when detecting, different water leakage sounds need to be distinguished according to the heard water leakage sounds.

9. Effectively confirming water leakage sound

In order to effectively check the leakage sound, the external noise is first intercepted by adjusting the filter. When the device is used at night, noise caused by water flow at the positions of the valve and the elbow can be reduced to the minimum because no person uses water, external noise such as automobile and machine sound can be restrained, and the detection effect can be improved by means of pressure of water pressure during the day.

10. Confirmation work

The position where the sound is substantially the maximum is the position where water leakage occurs, and therefore, if it is determined that the target position has been reached after confirmation is repeated 2-3 times, the probe main body 2 is turned off and construction is performed. And judging whether water leakage exists at other positions or not through a pressure test after the construction and repair are finished.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
