Description
Technical field
The utility model relates to the leakage detecting instrument field, relates in particular to the helium mass spectrometer leak detector field.
Background technology
At present, when hunting leak with simple leak locator, if adopt the aeration leak detection, the leak detection suction gun is indispensable, and it is connected on the leak locator, regulates suitable gas flow, guarantees that instrument is in normal leak detection state, and seized container fills with several atmospheric helium.During leak detection, the suction nozzle of suction gun moves along position to be checked, when not running into small opening; The suction nozzle that always has little air to pass through suction gun flows into analyzer; When running into small opening, the helium in the container spills through small opening is shallow, is sucked in the analyzer by suction gun; It is big that the indication of instrument just becomes, and can judge the position of small opening and the size of its leak rate thus.Stamping container is implemented mass spectrum leak detection, can improve the quality of products greatly.In recent years, the requirement that high pressure vessel is hunted leak constantly increases, and makes the mass spectrum leak detection technical application in many technical fields, thereby the leak detection suction gun also is put into the row of indispensable parts.
The leak detection suction gun of present domestic employing partly is import, and it is small and exquisite, reliable, but costs an arm and a leg.Domestic this product does not also form series, and the product that has is to adopt the needle-valve principle design, and its volume is big, difficult processing.
The utility model content
The utility model technical matters to be solved is: provide a kind of helium mass spectrometer leak detector simple in structure, that cost is low, the suction gas flow is stable special-purpose suction gun.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The special-purpose suction gun of helium mass spectrometer leak detector; Said suction gun includes a stainless steel capillary I, stainless steel capillary II, handle, suction gun seat, and the end of said stainless steel capillary I is nested in the stainless steel capillary II, suction pipe of suit outside the junction of said stainless steel capillary I and stainless steel capillary I, II; A suction nozzle is installed on the top of said suction pipe; And with sealing gasket I sealing, the front end of said suction nozzle is installed a sucker, said sucker through internal thread twist with suction nozzle on; And seal with raw material band, embed a filter in the suction nozzle; The sealing nut I screws on suction pipe end and handle; Have through hole on the said handle, said stainless steel capillary II is passed the through hole on the handle, and the sealing nut II screws on stainless steel capillary II and handle; Said suction gun cover for seat is contained in outside the handle; Said suction gun seat is connected with metal hose, is connected with the suction gun hose adapter between said metal hose and the suction gun seat, and said metal hose connects the suction gun gas outlet.
Stainless steel capillary I and stainless steel capillary II are the half-hard state stainless steel capillary.
The joint of said stainless steel capillary I and stainless steel capillary II seals with fluid sealant.
The utility model has the advantages that: the utility model is simple in structure, and material therefor is a conventional material, and cost is low, and applicability is strong, sucks gas flow and stablizes, and gas circuit is difficult for stopping up long service life.
