What about leaking pipes in common areas of small communities and how to check for leaks?

Nowadays, whether it is a community, or public facilities, there will be a fire pipeline, it is worth noting that sometimes there will be a leak, which can lead to a series of failures, for this reason, the daily need to do some detection work, so as to know early, early prevention, early solution.

Water leak detection of fire pipes.


First, with the pipeline leak detection company introduced by closing the main stem valve of the fire protection network, confirm the leak section, observe the ground to confirm the leak point. Confirm that the valve can be closed completely, according to our experience, the domestic valve, especially after 1, 2 years after the installation of the valve, more than 70% are very difficult to close, the valve can be closed, you can confirm the approximate area of the leak.


Carefully check the state of the ground above the pipe in this area, there is no sinking, particularly wet, next to the sewer there is no stable clear water. This leak detection method is suitable for the general public and is not highly technical, but it is difficult to pinpoint the leak, and the excavation area is large, which is also easy to cause mis-excavation.


Second, the use of professional pipe leak detector. This is generally only professional leak detection companies are equipped with professional instruments, listening to the sound pole and pipe leak detector is the same way, experienced leak detection personnel use them to pinpoint part of the leak, buried at a depth of about 1.5 meters, the leak is not a large amount of water can also play a role.


Third, the pipeline leak detection company introduced quiet time to listen to the sound. 2:00 a.m., late at night, when the surrounding area is very quiet, follow the pipeline slowly, if the leak is very large, there is a certain probability that you can hear the sound of water leaks.

There are many kinds of water leak detection methods, such as regional installed meter method, listening method, acoustic shock method, infrared method, tracer element method, related signal detection and buried medium change detection method. Any kind of detection method is essentially detecting some kind of effect caused by water leakage, the more obvious the corresponding effect the simpler the detection. Currently widely used application method for listening to the sound method, acoustic shock method. This method refers to some kind of sound transmission tool to listen to the sound of water leakage, according to the size of the leakage sound and the characteristics of the medium to determine the location of the leakage, tools from simple mechanical listening to various types of listening to leak detection instrument is currently developing quite rapidly


Key points: water leakage triggers vibration and pronunciation effect


Hunan Puqi Geological Exploration Equipment Research Institute is a professional institution engaged in the research of pipeline leak detection equipment and urban pipeline loss reduction. Mainly committed to the underground pressure pipeline leak detector application technology research and scientific and technological research and has been jointly established with Harbin Institute of Technology, the thirteenth five-year national water special R & D base, and Hunan University of Science and Technology jointly established a strategic innovation cooperation base, and Algeria University reached a strategic partnership, our institute adhere to the "science and technology, strong hospital talent Our institute insists on the strategic goal of "science and technology, talents strengthen the institute", implements the policy of running the institute in an open manner, and the independent core leak detection technology in the field of research and development of new generation of underground pressure pipe leak detection equipment has attracted great attention in the industry, and the pipe leak detection series instruments have applied for many invention, utility model and appearance patents, forming its own unique technical characteristics and advantages.
