Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See figures.1.and.2, propose a kind of air-tightness detection device of the utility model one embodiment, comprise the first gland bonnet 10, second gland bonnet 20 and at least one first sensor 31 and at least one second sensor 32; Described first sensor 31 and the second sensor 32 are sensor of the same type, and first sensor 31 and the second sensor 32 can comprise pressure transducer, pressure transducer and various gas concentration sensors etc.In the present embodiment, gas pressure sensor and air pressure sensor etc. the sensor of measurement gas pressure can be replaced as a kind of type sensor and use, namely, when first sensor 31 is gas pressure sensor, the second sensor 32 can be air pressure sensor; And measure the sensor of a certain gas concentration and be somebody's turn to do the sensor that both are non-same kind.In this first gland bonnet 10 and the second gland bonnet 20, the sensor of different types can not be used in combination.Certainly, in a particular embodiment, need both to measure certain gas concentration, again when measurement gas pressure, can use simultaneously.
Described first gland bonnet 10 arranges at least two pores 40 and first sensor 31; Described second gland bonnet 20 is arranged at least one pore 40 and second sensor 32; At work, the airtight opening part being covered on test product 50 of described first gland bonnet 10, the second gland bonnet 20 is airtight is covered on place to be detected; At least one pore 40 on first gland bonnet 10 is closed, and all the other pores 40 are bled, and the pore 40 on the second gland bonnet 20 is bled; After the first sensor 31 of the first gland bonnet 10 and the second gland bonnet 20 correspondence and the second sensor 32 all collect specific data, then the pore 40 of bleeding of corresponding gland bonnet stops bleeding, on described first gland bonnet, the pore 40 closed of 10 starts ventilation, until when the first sensor 31 on the first gland bonnet 10 collects specific data, stop ventilation.
The air-tightness detection device of the present embodiment, first gland bonnet 10 and the second gland bonnet 20 is set, and the first gland bonnet 10 and the second gland bonnet 20 arrange above-mentioned first sensor 31 and the second sensor 32 respectively, first gland bonnet 10 is arranged two pores 40, by the cooperation of bleeding and inflating of first sensor 31 and two pores 40, the gas that can control in test product 50 is positioned at (a pressure, air pressure or certain gas concentration) steady state value, be equivalent to the measurement environment of test product 50 1 standards, the convenient data analysis contrast that second sensor 32 is gathered, judged accurately.
With reference to Fig. 1, in one embodiment, detect test product 50, the sidewall of test product 50 has a through hole (not shown), through hole arranges plug (not shown) and blocks, and detects the impermeability between plug and through hole.First select first sensor 31 and the second sensor 32 to be pressure transducer, and setting being positioned at the force value parameter of the pressure transducer of different sealing lid respectively, when reaching setting value, controlling the beginning of bleeding and inflating or end; Then by the airtight opening part being covered on test product 50 of the first gland bonnet 10, the second airtight through hole be covered on outside test product 50 of gland bonnet 20; Closed by a pore 40 on first gland bonnet 20 afterwards, another pore 40 starts to bleed outside the first gland bonnet 10, and meanwhile, the pore 40 of the second gland bonnet 20 also starts to bleed outside the second gland bonnet 20; When the pressure transducer in the first gland bonnet 10 collects setup parameter, stop to bleeding outside the first gland bonnet 10, when the pressure transducer in the second gland bonnet 20 collects setup parameter, stop bleeding outside the second gland bonnet 20; The pore 40 of sealing before opening the first gland bonnet 10, and inflated in the first gland bonnet 10 by this pore 40, until when the pressure transducer in the first gland bonnet 10 reaches setting value, stop inflation, namely can obtain the initial environment of specifying air pressure value; Pressure transducer in second gland bonnet 20 gathers the gas pressure change in the second gland bonnet 20, obtains one group of pressure delta data, finally by the Data Comparison in this group pressure delta data and database, judges that whether the impermeability of this test product 50 is qualified.In the present embodiment, the data that pressure transducer in second gland bonnet 20 gathers make curve as described in Figure 4, because the gas in the second gland bonnet 20 is by negative pressure supercharging gradually, so the data of pressure transducer collection in the second gland bonnet 20 diminish gradually, form a subtraction function curve, typical curve in this subtraction function curve and database contrasts, and judges that whether the impermeability of this test product 50 is qualified.
In another specific embodiment, above-mentioned pressure transducer can replace with baroceptor, or pressure transducer and baroceptor used in combination.Pressure transducer or baroceptor can also be replaced to oxygen concentration sensor.Such as, first first sensor 31 and the second sensor 32 is selected to be oxygen concentration sensor, and setting is positioned at the oxygen concentration value parameter of the oxygen concentration sensor of different sealing lid respectively, when reaching setting value, controlling bleeds and fill oxygen starts or terminates; Then by the airtight opening part being covered on test product 50 of the first gland bonnet 10, the second airtight through hole be covered on outside test product 50 of gland bonnet 20; Closed by a pore 40 on first gland bonnet 10 afterwards, another pore 40 starts to bleed outside the first gland bonnet 10, and meanwhile, the pore 40 of the second gland bonnet 20 also starts to bleed outside the second gland bonnet 20; When the oxygen concentration sensor in the first gland bonnet 10 collects setup parameter, stop to bleeding outside the first gland bonnet 10, when the oxygen concentration sensor in the second gland bonnet 20 collects setup parameter, stop bleeding outside the second gland bonnet 20; The pore 40 of sealing before opening the first gland bonnet 10, and filled oxygen in the first gland bonnet 10 by this pore 40, until when the oxygen concentration sensor in the first gland bonnet 10 collects setting value, stop filling oxygen, the initial environment of designated value namely can be obtained; Oxygen concentration sensor in second gland bonnet 20 gathers the change of the oxygen concentration in the second gland bonnet 20, obtains one group of oxygen concentration delta data.As shown in Figure 5, these group data form an increasing function curve mutually, and the curve comparison that the data in this increasing function curve and database can be formed, judges that whether the impermeability of this test product is qualified.In other embodiments, oxygen concentration sensor can replace with as nitrogen gas concn sensor gas concentration sensor, certainly, does not select concentration of toxic gases sensor, occurs to prevent dangerous situation.
With reference to Fig. 3, in the present embodiment, above-mentioned air-tightness detection device also comprises for shutoff test product 50 without the need to measuring the sealing block 70 of bubble-tight opening part, such as, test product 50 there is multiple perforation 51, need each perforation 51 to close, to complete bubble-tight detection smoothly, so sealing block 70 is exactly the device for each ventilation position of shutoff when detecting.
With reference to Fig. 3, in the present embodiment, above-mentioned air-tightness detection device also comprises the holder 60 for fixing described test product 50, when detecting test product 50, is fixedly installed on holder 60 by this test product 50, convenient detection.
With reference to Fig. 3, in the present embodiment, above-mentioned air-tightness detection device also comprises multiple sealing adaptor 41 for connecting pore, and sealing adaptor 41 can facilitate pore 40 to connect vacuum extractor or aerating device, improves the speed of air-leakage test.
In the present embodiment, also can use the equipment central controllers such as vacuum extractor, aerating device and central controller and be connected each sensor vacuum extractor and aerating device, according to the setup parameter of sensor 30, control the work of vacuum extractor, aerating device, central controller can also the impermeability of final analysis test product whether qualified etc.
