Description
Technical field
The utility model relates to aluminium foil film quality detection technique field, particularly a kind of frock for the leak detection of aluminium foil film.
Background technology
Be conventionally used to during aluminium foil film detects and use oxygen as detection gas, because oxygen molecule is comparatively large, the testing requirement of high-quality aluminium foil film cannot be met, therefore carry out the testing of high-quality aluminium foil film mainly with helium as detection gas.
Helium mass spectrometer leak detecting technology is indispensable a kind of technology in vacuum leak hunting field, and because leak detection efficiency is high, simple and easy to operate, instrument is quick on the draw, and precision is high, is not subject to the interference of other gases, is widely applied in resistance furnace leak detection.Helium mass spectrometer leak detector is according to mass-spectrometry principle, the air-leakage test instrument made as probe gas with helium.The mass spectrum chamber be made up of ion gun, analyzer, gatherer, Penning gauge and extract system and electrical part are graded and are formed.Filament emission in mass spectrum chamber electronics out, vibrate to and fro in indoor, and with indoor gas with mutually collide through the helium that small opening enters people indoor and make it be ionized into positive ion, these helium ions enter people magnetic field under accelerating field effect, because Lorentz force effect produces deflection, form arc-shaped rail, change accelerating potential and the ion of different quality can be made to arrive receiving pole by magnetic field and receiving slot and be detected.Spray helium method, to inhale helium method be the two kinds of methods the most frequently used in resistance furnace leak detection of helium mass spectrometer leak detector.
Because aluminium foil film is flake structure, when carrying out aluminium foil film thin slice leak detection experiment with helium mass spectrometer leak detector.Therefore a kind of helium mass spectrometer leak detector that can be arranged on is needed to assist the frock of carrying out similar film series products leak detection experiment.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of frock for the leak detection of aluminium foil film.
For solving the problem, the utility model provides following technical scheme:
For a frock for aluminium foil film leak detection, comprise the upper cover and lower cover that are bolted; Air storing cavity and inlet suction port is covered with on described; Pumping chamber and gas outlet is covered with under described; In described pumping chamber, supporting plate is installed; Described supporting plate is evenly distributed with leakage hole.
Further, described upper cover and lower cover are all one-body molded flange; The flange of described upper cover offers through hole; The flange of described lower cover offers threaded hole.
Further, the lower surface of described upper cover and the upper surface of upper cover are equipped with seal groove; In described seal groove, O-ring seal is installed.
Further, described inlet suction port is provided with rapid-acting coupling.
Further, the step for supporting supporting plate is provided with in described pumping chamber.
Beneficial effect: a kind of frock for the leak detection of aluminium foil film of the present utility model, clamping can be carried out and auxiliary leak detection experiment to film series products, and the sealing of the air storing cavity on film top and the pumping chamber of film bottom can be ensured, be arranged on down the supporting plate covered to support film, prevent the high vacuum produced in pumping process from making Film Tear.

Embodiment
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
Referring to figs. 1 through a kind of frock for the leak detection of aluminium foil film shown in Fig. 4, comprise the upper cover 1 and lower cover 2 that are bolted; Described upper cover 1 is provided with air storing cavity 1a and inlet suction port 1b; Described lower cover 2 is provided with pumping chamber 2a and gas outlet 2b; In described pumping chamber 2a, supporting plate 3 is installed; Described supporting plate 3 is evenly distributed with leakage hole.
Described upper cover 1 and lower cover 2 is all one-body molded flange; The flange of described upper cover 1 offers through hole; The flange of described lower cover 2 offers threaded hole.
The lower surface of described upper cover 1 and the upper surface of upper cover 1 are equipped with seal groove; O-ring seal 4 is installed in described seal groove.
Described inlet suction port 1b is provided with rapid-acting coupling 5.
The step for supporting supporting plate 3 is provided with in described pumping chamber 2a.
In the leak detection experiment carrying out aluminium foil film, the foursquare aluminium foil film of cutting one piece, is placed on the top of supporting plate 3, is covered by upper cover 1 and use bolt presses.
Wherein, O-ring seal 4 ensure that the sealing of air storing cavity 1a and pumping chamber 2a in the mounted state, and rapid-acting coupling 5, for extraneous helium pipeline, passes into helium in air storing cavity 1a.
It is worth emphasizing that, higher vacuum tightness can be formed in pumping chamber 2a in testing process, supporting plate 3 pairs of aluminium foil films have carried out effective support and have prevented aluminium foil film to be torn under the effect of high vacuum suction, and then cause helium directly to enter in helium mass spectrometer leak detector, normally carrying out of impact experiment.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
