Description
Technical field
The utility model relates to a kind of steel pipe leakage detection apparatus that is mainly used in the high chemical industry series products of sealing security requirement.
Background technology
Along with the progress of epoch with science and technology, the chemical industry series products has used in enormous quantities in real society, because it is poisonous, harmful that the gas of chemical industry series products or liquid mostly are greatly, be dispersed in the air and can damage human body, previously used all is that gas or liquid are transmitted by pipeline, of long duration, harmful gas can be to a certain degree corrosion pipeline, thereby the leakage of pipeline has appearred, such pipeline is revealed and can't be detected, and toxic and harmful has been dispersed in the air virtually, has caused harm, owing to be single pipe, sealing is poor like this.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of sealing safe safety guard.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of steel pipe leakage detection apparatus, be used to test the sealing of steel pipe, comprise shell, be provided with first steel pipe and second steel pipe in the shell, first steel pipe and second steel pipe be cutting ferrule cooperate and the first steel pipe plug in second steel pipe, gapped between first steel pipe and second steel pipe, be welded with first flange plate and second flange plate between the first steel pipe front-end and back-end and the shell respectively, be welded with the 3rd flange plate and the 4th flange plate between the second steel pipe front-end and back-end and the shell respectively, first flange plate, the 3rd flange plate and second flange plate, gapped between the 4th flange plate, in first flange plate and the 3rd flange plate gap, offer the high-pressure valve that is used for injecting gas or liquid, offer tensimeter in second flange plate and the 4th flange plate gap, tensimeter also can be pressure sensor, tensimeter and warning device UNICOM, if gas or liquid are when producing leakage by first steel pipe, the indication on tensimeter or the pressure sensor produces fluctuation or reports to the police.
Also be provided with the import of gas in first steel pipe being carried out heat interchange between the 3rd flange plate and the 4th flange plate.
First flange plate and second flange plate and shell can be welded with at least one steel pipe, and the 3rd flange plate and the 4th flange plate and shell can be welded with at least one steel pipe, can increase flow and the useful area that increases heat interchange in the steel pipe.
The beneficial effects of the utility model are, steel pipe leakage detection apparatus of the present utility model is mainly used in the safe chemical industry series products of sealing, when import injecting gas or liquid, in the gap, keep certain pressure, if gas or liquid in steel pipe by the time produce to leak, manometric indication can produce fluctuation and in time report to the police, and can in time notify the staff, has reduced the pollution to air.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cut-open view of the present utility model.
1. shells among the figure, 2. first steel pipe, 3. second steel pipe, 4. first flange plate, 5. second flange plate, 6. the 3rd flange plate, 7. the 4th flange plate, 8. high-pressure valve, 9. tensimeter.
Embodiment
