Technical field
The utility model relates to dryer flaggy leakage detection apparatus, specifically, relates to a kind of vacuum freeze dryer plate layer leakage detection apparatus.
Background technology
The flaggy of vacuum freeze drier adopts high-quality 316L stainless steel to make, and is welded with the passage of refrigerating medium circulation between the corrosion resistant plate of two of up and down, can carry out cooling or heating to product, therefore the flaggy requirement is smooth, smooth, and enough intensity is arranged, certain is withstand voltage, use for a long time indeformable, ne-leakage.Present stage be mainly that method by bulge test realizes for the leak detection of vacuum freeze drying agent flaggy, but the method easily is subjected to the impact of surrounding environment, and accuracy of detection is lower.This is the deficiencies in the prior art part.
The utility model content
Technical scheme to be solved in the utility model is to provide a kind of vacuum freeze dryer plate layer leakage detection apparatus, has improved accuracy of detection.
The utility model adopts following technological means to realize goal of the invention:
A kind of vacuum freeze dryer plate layer leakage detection apparatus, comprise closed container, it is characterized in that: be provided with the detection flaggy in described closed container, described detection flaggy connects helium mass spectrometer leak detector and gauge tap one, described detection flaggy is also respectively by gauge tap two, gauge tap three Bonding pressure display and vacuum extractors, and described detection flaggy also connects the helium input port by gauge tap four.
As the further restriction to the technical program, described gauge tap one, two, three, four is all to adopt manual ball valve.
As the further restriction to the technical program, described vacuum means is set to the vacuum pumping pump group.
As the further restriction to the technical program, described detection flaggy is the Bonding pressure table also.
As the further restriction to the technical program, described pressure display unit is the vacuum pressure display.
compared with prior art, advantage of the present utility model and good effect are: vacuum pumping pump group of the present utility model is used for finding time to detect flaggy, the vacuum pressure display is used for showing the vacuum pressure value that detects flaggy, helium mass spectrometer leak detector is used for closed container is vacuumized, to detect flaggy during use and put into closed container, by pipeline, all parts is connected afterwards, start the vacuum pumping pump group flaggy of finding time, to vacuum pressure display registration be 50Pa, close the vacuum pumping pump group, pour helium to tensimeter and show 0.5MPa in flaggy, then starting vacuum pumping pump group closed container to the vacuum pressure display registration of finding time is 50Pa, close the pump group, opening helium mass spectrometer leak detector continues closed container is found time, treat that vacuum pressure display registration is 10Pa, if helium mass spectrometer leak detector alarm free, the flaggy leak rate meets the requirements, product is qualified.The utility model precision is higher, and testing result is more reliable, has improved the quality of product.
