Description
Technical field
The present invention relates to the leakage detection apparatus of pressure vessel, especially a kind ofly detect multi cavity container or detect the device of a plurality of seal of vessel property simultaneously with helium.
Background technology
The helium mass spectrum leak detection method is with its high sensitivity and accuracy and be applied to usually on the higher pressure vessel of anti-leak grade.The helium mass spectrum leak detection method can be divided into basically and vacuumizes the outside with helium internal pressurization method and device interior and apply these two kinds of helium.
Plate type finned heat exchanger is a kind of heat exchanger that is usually used in gas separation and low temperature field, and the leakproof grade is higher, need guarantee the impermeability of heat interchanger usually through the helium mass spectrum leak detection method.Because of plate type finned heat exchanger is a kind of pressure vessel that can allow the heat exchange simultaneously of multiply medium, it usually has a plurality of passages (or claiming chamber), therefore needs respectively each passage to be hunted leak, and is also referred to as inspection and leaks outside; In addition, except each passage possibly be in communication with the outside leak, also possibly occur leaking between adjacent two passages, be referred to as interior leakage usually.
Introduce plate type finned heat exchanger among the NB/T 47006-2009 in detail and carried out the helium mass spectrum detection method with interior leakage that leaks outside.Leak outside when detecting, at first tested passage is linked to each other with helium mass analyzer, then plate-fin heat exchanger is used plastic bag sealing, be full of helium or helium and nitrogen mixture between polybag and the plate type finned heat exchanger, then tested passage is carried out helium mass spectrum leak detection.After detection finishes, change a passage and repeat aforesaid operations, carry out the detection of next passage.When omission is surveyed in carrying out, earlier tested passage is linked to each other with helium mass analyzer, feed helium or helium and nitrogen mixture at adjacency channel then, omission is surveyed in carrying out.After detection finishes, change the interior omission survey that passage repeats other adjacency channels.
Because plate-fin heat exchanger has a plurality of passages usually, therefore when carrying out the helium inspection, need repetition joint detection appearance and heat interchanger repeatedly.Especially some complicated plate-fin heat exchanger has ten a plurality of fluids sometimes, when the heat exchanging device is done helium inspection and leaked outside with interior leakages, need carry out repeated dismounting connection like this, and it is very loaded down with trivial details to work, time-consuming very long, and repeated priming vacuum unit repeats to fill helium.
