Description
Technical field
The utility model relates to air leakage detecting instrument instrument, particularly a kind of ultrasonic gas gas leak tester.
Background technology
Along with the robotization of modern enterprise and intelligence degree more and more higher, especially more next high in Science & Technology Demands, especially in present petrochemical enterprise, along with up-to-dateness is more and more higher, production equipment in petroleum chemical enterprise becomes increasingly complex, and its structure and program are often coiled and made friends with mistake.On the other hand, owing to being special Petroleum Production, due to the singularity of oil, the characteristic such as inflammable and explosive, toxic and corrosion contamination.Cause the seal degree in petroleum chemical enterprise, and leakage problem, become to affect petroleum chemical enterprise's quality of production, and the major issue of production efficiency.On the other hand because the equipment of above-mentioned petroleum chemical enterprise, structure are very complicated, and each interface, pipeline very numerous and diverse, for enterprise, the problem of this respect highlights fairly obvious.In addition, production material in petroleum chemical enterprise, all often gas or liquid, its perviousness, extremely strong with circulation, often a little seal point problem, will cause large security incident, light then cause the pollution of large-scale energy dissipation and large area environment, heavy then cause the serious accidents such as fire explosion.Therefore, for seal degree and the leak detection of this kind of enterprise, just become the major issue of enterprise safety operation.
At present, to the detection method that container and pipeline gas leak, manual patrol method and instrument detection method two class is mainly contained.From the angle of detected parameters, instrument detection method can be divided into direct Detection Method and indirect detection method.Direct Detection Method utilizes the detector be arranged on outside pipeline, directly measures the conveying gas leaked into outside pipeline, thus reach the object detecting and leak.Indirect detection method comprises difference in flow method, motion stress method, sealing pressing method and supercritical ultrasonics technology etc.
Supersonic reflectoscope monitors the sound of gas flow through leak by sharp, realizes leakage alarm.By the science and technology of this kind of advanced person, superpower performance, the perfect function replacing human body, can improve the efficiency and effect of comprehensively improving Leak Detection.But existing supersonic reflectoscope complex structure, cost of manufacture is high, and does not generally possess the function of carrying out sealing in time to air leak position.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of ultrasonic gas gas leak tester, efficiently can detect Leakage Gas situation fast, and have timely enclosing function.
The utility model solves the technical scheme that its technical matters adopts: a kind of ultrasonic gas gas leak tester, comprise detector shell and main handle, it is characterized in that, described enclosure is isolated into detection space and sealing space, chip board is provided with in described detection space, described detection space top is provided with ultrasonic sensor, described chip board is disposed with pre-amplification circuit, bandpass filter, secondary amplifying circuit, power driving circuit, described detection space side is provided with receiver interface; Closing device is provided with in described sealing space; Described main handle inside is provided with battery case.
Good effect of the present utility model: the utility model can the leakage of the various pressure system of Non-Destructive Testing, and vibrational power flow is reasonable, easy to operate, highly sensitive.Simultaneously the utility model Detection results is comprehensive, can while detecting gas leak phenomenon the very first time sealed, reduce resource loss and potential safety hazard, sealing operation is simple and convenient.

Side, described sealing space is also provided with assist handle 13.
Described closing device comprises the holder 14 be arranged on bottom sealing space 4, holder 14 is provided with the resistance to air bottle 15 that fluid sealant is equipped with in inside, its position of bottleneck place is provided with jet blower compressing tablet 16 and goes out sebific duct 17, and described jet blower compressing tablet 16 is connected with depression bar 18.
The leakage ultrasonic signal that the utility model ultrasonic sensor produces for obtaining pipe leakage, described leakage ultrasonic signal is input to audio frequency processing circuit after signal amplification circuit, the low frequency signal that the conversion of leakage ultrasonic high-frequency signal can be listened for people's ear by audio frequency processing circuit.The leakage ultrasonic signal of acquisition is carried out voltage amplification by pre-amplification circuit described in the utility model, described bandwidth-limited circuit is for filtering the noise that in ground unrest in leakage ultrasonic signal and circuit, device or circuit produce, and the input end of described bandwidth-limited circuit is connected with the output terminal of pre-amplification circuit.The described input end of secondary amplifying circuit is connected with the output terminal of bandwidth-limited circuit.
When using the utility model leakage position to be detected, the gum outlet going out sebific duct can be aimed at leakage position, hold assist handle simultaneously and move depression bar, fluid sealant sprays in resistance to air bottle, seals leakage position temporarily.
Above-describedly be only preferred embodiment of the present utility model; be understood that; the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; and be not used in restriction protection domain of the present utility model; all any amendments, equivalent replacement etc. made within thought of the present utility model and principle, all should be included within protection domain of the present utility model.
