Background
With the progress of society, buildings such as office buildings are more and more, and various pipelines such as water pipes, air-conditioning pipelines, electric wire pipelines, gas pipelines and the like are densely distributed in the buildings such as office buildings. Some pipelines must be sealed and cannot be leaked, and the traditional pipeline inspection method is to use high-pressure water for inspection, which causes two hidden dangers. Firstly, the method comprises the following steps: if the leakage point exists, high-pressure water is sprayed out of the leakage point, and potential harm is caused to people. Secondly, the method comprises the following steps: after the inspection is finished, water can be remained in the pipeline, and the pipeline can be corroded subsequently. In addition, the detection capability of the leakage point detector for tiny leakage points is low, and the leakage point detector is often not capable of detecting the tiny leakage points.
Disclosure of Invention
The purpose of the invention is as follows: the leak detector for the building is provided, and can be used for conveniently and quickly detecting the sealed pipeline of the building.
The technical scheme is as follows: a leakage detector for buildings comprises a high-pressure air generating device, a flowmeter, a one-way valve, an air inlet pipe, a heating device, a barrel cover, an air outlet pipe, a power supply and a control and display unit, wherein a smoke manufacturing solution is filled in the barrel, the heating device is immersed in mineral oil, the control and display unit controls the heating device and the high-pressure air generating device to be switched on and off, the flowmeter is connected with the control and display unit through a data line, and high-pressure gas generated by the high-pressure air generating device passes through the flowmeter and then is introduced into the barrel through the one-way valve.
Further, the leak detector for buildings further comprises a filter and a nitrogen generator, wherein the filter is connected with the high-pressure air generating device through a pipeline, and the nitrogen generator is located between the filter and the flowmeter.
Furthermore, the leak detector for buildings also comprises a pressure sensor which is connected with the control and display unit through a data line.
Further, the heating device also comprises an inner container, and the heating device is arranged on the inner container.
Further, the barrel is a steel barrel formed in one step.
Further, the smog-producing solution is 98% -99% food grade mineral oil and 1% -2% fluorescer.
Further, the barrel body and the barrel cover are fixed through bolts, and the barrel body and the barrel cover are provided with sealing rings.
Further, the filter is a three-stage filter, the first stage is a 5 micron filter, the second stage is a 0.01 micron filter, and the third stage is an activated carbon filter.
During operation of the leak detector for building, with the gas outlet with wait to detect the pipe connection, be equipped with heating device on-off control button and high-pressure air generating device shift knob on control and the display element, open heating device, solution is made to heating smog, produce smog, open high-pressure air generating device, produce high-pressure gas and filter behind the filter and lead to nitrogen gas generator after impurity, oxygen in the nitrogen gas generator will be got rid of with gas, produce nitrogen gas, let in the barrel, the smog that will produce blows off, then smog lets in the sealed pipeline that waits to detect through the outlet duct, if there is the gap, smog can emerge from the gap. When the smog manufacturing solution contains the fluorescent agent, the tiny crack can be found out through the irradiation of the fluorescent lamp, and the use safety of the pipeline is improved. In addition, the pressure sensor can feed back the internal pressure of the whole detection system in real time, and can judge whether the detection pipeline has leakage or not.
The principle of the invention is as follows: the method comprises the steps of heating smog to make solution to generate smog, generating high-pressure airflow by combining a high-pressure air generating device to blow the generated smog into a pipeline to be detected, and looking for a leakage point in the pipeline by observing whether the smog overflows or not. The pressure sensor is arranged, so that the pressure in the pipeline can be monitored and detected in real time, and whether the whole detection system has a leakage point or not can be judged.
Has the advantages that: compared with the prior art, the invention has the advantages that the solution is produced by heating the smoke to produce the smoke, the high-pressure air generating device is combined to produce the high-pressure air flow to blow the produced smoke into the pipeline to be detected, and the leakage point in the pipeline is searched by observing whether the smoke overflows or not.
