Abstract
Disclosed is a high pressure piston type accumulator mixing gas quantification leak detection apparatus, comprising a bottom-opened container and a leak detector, wherein the container is provided with a test hole; the leak detector comprises a detecting tube and a detecting probe extending into the container via the test hole; and the detecting probe is connected with the leak detector body via the detecting tube. The opened edge of the container bottom is provided with an elastic sealing gasket. The high pressure piston type accumulator mixing gas quantification leak detection apparatus features scientific principle, simple structure, and rapid and accurate detection, and is a detecting instrument capable of precisely detecting the leakage rate of a high voltage accumulator product. The high pressure piston type accumulator mixing gas quantification leak detection apparatus can carry out detection over the high operating pressure gases (40MPa) and replace the detectable gas with the relatively inexpensive inert gas to reach high pressure. Moreover, the previous qualitative detection is transformed into quantification leak detection, thereby making the out-factory qualified rate of the high pressure accumulators reach 100%, substantially saving the cost, and establishing great reputation for enterprises.
Description
Technical field
The utility model relates to a kind of gas leak detection instrument, is specifically related to a kind of high pressure piston formula accumulator mixed gas quantitative leak device.
Background technology
Be filled with gases at high pressure in the high pressure piston formula accumulator, its each sealing position can produce leakage, and domestic more is at present to adopt the detection method that is coated with suds; This detection method is simple; But it is not high to detect degree of accuracy, has influence on high pressure piston formula accumulator ex factory pass rate, thereby causes many high pressure piston formula accumulators life-span in use short; Major defects such as slip is high, and working pressure is low.
The utility model content
The utility model provides a kind of high high pressure piston formula accumulator mixed gas quantitative leak device of degree of accuracy that detects in order to solve weak point of the prior art.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: high pressure piston formula accumulator mixed gas quantitative leak device; Comprise container and leak locator that the bottom is uncovered; Offer on the container and detect the hole, leak locator comprises detector tube and extend into the detection probe in the container through detecting the hole that detection probe is connected with the body of leak locator through detector tube.
The edge that said container bottom is uncovered is provided with elastic sealing gasket.
Adopt technique scheme, at first in accumulator, charge into a small amount of detectable gas, charge into relatively inexpensive inert nitrogen gas then to preliminary filling pressure; Accumulator is put into the container of known volume; Begin leak test this moment, detects the concentration of detectable gas, passes through the concentration of detectable gas in the preliminary filling gas again; Button enclosure volume and time, utilize the equation of gas state to calculate the mixed gas slip.
The utility model principle science, simple in structure, quick and precisely; For the slip that accurately detects the high pressure accumulator product provides a kind of detector instrument; Can replace detectable gas to reach high pressure with relatively inexpensive inert gas to high workload pressure (40MPa) gas leak detection, and by the former qualitative quantitative leak that transfers to; Make the high pressure accumulator ex factory pass rate reach 100%, fully practiced thrift cost and be the good reputation of enterprise's creation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The high pressure piston formula accumulator mixed gas quantitative leak device of the utility model; Comprise bottom uncovered container 1 and leak locator 2, container 1 is a rectangular shape, offers on the sidewall of container 1 to detect hole 3; Leak locator 2 comprises detector tube 4 and extend into the detection probe 5 in the container 1 through detecting hole 3 that detection probe 5 is connected with the body of leak locator 2 through detector tube 4.Uncovered edge, container 1 bottom is provided with elastic sealing gasket 6.
The utility model at first charges into P in accumulator 7 (volume V) when detecting use
1(0.4～0.8MPa) sulfur hexafluoride gas charges into nitrogen to P to pressure then
2Pressure (21～40MPa), calculate the volume content (x) that charges into sulfur hexafluoride in the accumulator 7 interior mixed gass under the atmospheric pressure, x=P according to The Ideal-Gas Equation
1V/P
2V.Then accumulator 7 is put into known volume (container 1 v); After the uncovered button in the bottom of container 1 covers certain hour on flat board or the plane earth (t); Elastic sealing gasket 6 plays good sealing function; The volumetric concentration (y) of sulfur hexafluoride so just can calculate mixed gas slip=yv/xt, slip≤1*10 in the detection probe 5 of leak locator 2 (sulphur hexafluoride leak detection appearance) detection receptacle
-4Ml/s.
