Abstract
The utility model discloses a gas leakage detection system, which comprises a gas source and a detection box, wherein the gas pressure of the gas source is higher than the internal gas pressure of a detected gas pipeline; the detection box comprises a box body, and a depressurizing valve, a pressure meter, a switch valve and a flow meter, which are arranged on the box body; an inlet end of the depressurizing valve is connected and communicated with the gas source, and an outlet end of the depressurizing valve is simultaneously communicated with one end of the switch valve and the pressure meter; the other end of the switch valve is connected and communicated with the inlet end of the flow meter; and the outlet end of the flow meter is connected and communicated with the detected gas pipeline. The gas leakage detection system is simple in structure and can accurately measure the gas leakage of the detected gas pipeline.
Description
Technical field
The utility model relates to the gas permeation amount detection systems of a kind of detection system, particularly a kind of gas piping.
Background technology
Gas piping all need carry out impermeability before use usually and detect, to judge whether accords with production standard of this gas piping.At present, the checkout equipment of prior art all can only detect this gas piping mostly qualitatively and whether have gas leakage, and the checkout equipment that minority has gas permeation amount measuring ability complex structure not only, and accuracy of detection is not high yet.
The utility model content
The technical matters that the utility model will solve is to provide a kind of not only simple in structure, and can accurately measure the gas permeation amount detection systems of tested gas piping gas permeation amount.
For solving the problems of the technologies described above; The utility model provides a kind of gas permeation amount detection systems of following structure: comprise source of the gas and detection case; The gaseous tension of source of the gas is higher than the gaseous tension in the tested gas piping; Detection case comprises casing and is arranged on reduction valve, tensimeter, switch valve and the flowmeter on the casing, and the entrance point of reduction valve is connected with source of the gas and communicates, and the endpiece of reduction valve is connected with end of switch valve and tensimeter simultaneously and communicates; The switch valve other end is connected with the entrance point of flowmeter and communicates, and the endpiece of flowmeter is used for being connected with tested gas piping and communicates.
After adopting said structure, compared with prior art, the utlity model has following advantage: when need carry out the impermeability detection to tested gas piping; Earlier the endpiece of flowmeter is connected with tested gas piping and communicates, regulate reduction valve then, the interior gaseous tension of the gaseous tension that makes the reduction valve endpiece and tested gas piping is consistent; Then open switch valve, at this moment, if the impermeability of tested gas piping is very good; There is not the gas permeation situation; Gaseous tension in the then tested gas piping can remain constant, and consistent with the gaseous tension of reduction valve endpiece, so the numerical value that flowmeter showed will be always zero; And if there is the gas permeation situation in tested gas piping because of impermeability is relatively poor; Then will certainly cause the gaseous tension in the tested gas piping to descend; Thereby make between tested gas piping and the reduction valve endpiece and pressure reduction occurs; At this moment; The gas medium that the is positioned at reduction valve endpiece place flowmeter of will flowing through enters into tested gas piping tested gas piping is carried out gas make-up, in this course, the gas flow of the flowmeter of flowing through will by flowmeter record; And this gas flow that flowmeter write down is the accurate gas permeation amount of tested gas piping, so the staff can accurately judge whether accords with production standard of tested gas piping through observation data on flows that flowmeter showed.By on can know that the utility model gas permeation amount detection systems is not only simple in structure, and can accurately measure the gas permeation amount of tested gas piping.
Description of drawings
Fig. 1 is the structural principle synoptic diagram of the utility model gas permeation amount detection systems when being connected with tested gas piping.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model gas permeation amount detection systems is done further to specify.
As shown in Figure 1; In this embodiment; The utility model gas permeation amount detection systems comprises source of the gas 1 and detection case, and the gaseous tension of source of the gas 1 is higher than the gaseous tension in the tested gas piping 7, and detection case comprises casing 2 and is arranged on reduction valve 3, tensimeter 4, switch valve 5 and the flowmeter 6 on the casing 2; The entrance point of reduction valve 3 is connected with source of the gas 1 and communicates; The endpiece of reduction valve 3 is connected with end of switch valve 5 and tensimeter 4 simultaneously and communicates, and switch valve 5 other ends are connected with the entrance point of flowmeter 6 and communicate, and the endpiece of flowmeter 6 is used for being connected with tested gas piping 7 and communicates.
The principle of work of the utility model gas permeation amount detection systems is: when need carry out the impermeability detection to tested gas piping 7; Earlier the endpiece of flowmeter 6 is connected with tested gas piping 7 and communicates, regulate reduction valve 3 then, the interior gaseous tension of the gaseous tension that makes reduction valve 3 endpiece and tested gas piping 7 is consistent; Even the numerical value that tensimeter 4 is shown is identical with gas pressure value in the tested gas piping 7; Then open switch valve 5, at this moment, if the impermeability of tested gas piping 7 is very good; There is not the gas permeation situation; Gaseous tension in the then tested gas piping 7 can remain constant, and consistent with the gaseous tension of reduction valve 3 endpiece, so the numerical value that flowmeter 6 is shown will be always zero; And if there is the gas permeation situation in tested gas piping 7 because of impermeability is relatively poor; Then will certainly cause the gaseous tension in the tested gas piping 7 to descend; Thereby make between tested gas piping 6 and reduction valve 3 endpiece and pressure reduction occurs; At this moment; The gas medium that the is positioned at reduction valve 3 endpiece places flowmeter 6 of will flowing through enters into tested gas piping 7 tested gas piping 7 is carried out gas make-up, and in this course, the gas flow of the flowmeter 6 of flowing through will be by 6 records of flowmeter; And this gas flow that flowmeter 6 is write down is the accurate gas permeation amount of tested gas piping 7, so the staff can accurately judge whether accords with production standard of tested gas piping 7 through the data on flows that shown of observation flowmeter 6.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
