Description
Technical field
The utility model relates to a kind of gas leak tester whether leaking gas with detection vacuum bag.
Background technology
At present, the vacuum bag gas leak tester generally using in prior art comprises by vacuum detecting casing and case lid the be tightly connected sensing chamber forming and the vacuum pump that can vacuumize sensing chamber, vacuum detecting casing and/or case lid are transparent, case lid can be opened with respect to vacuum detecting casing, in vacuum detecting casing, can fill water, case lid below is provided with the pressing plate for vacuum bag being pressed on to water.Close upper box lid and vacuum detecting box sealing can be formed to sensing chamber, vacuum pump connects sensing chamber by pipeline.While detecting operation, the vacuum bag that needs are detected is placed in the transparent airtight casing that water is housed, vacuum bag is pressed in water, then utilize vacuum pump to vacuumize transparent casing, after reaching certain vacuum degree, judge in heat-sealing place of vacuum bag and whether have bubble to emerge, thereby judge whether gas leakage.But this type of vacuum bag gas leak tester is to utilize vacuum pump to make the formation vacuum environment of sensing chamber in the time of work, therefore inevitably exist following defect: 1. can produce larger noise when the pump housing is worked.2. when the pump housing is worked, be evacuated gas through pump body compression, give off hot off-air, pollute the environment of laboratory, product control chamber.3. the pumping fluid of will regularly annotating, maintenance is loaded down with trivial details, and cost is high.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of novel structure, vacuum pump less, and pollution and noise are little, detect easy to operate vacuum bag gas leak tester.
In order to realize foregoing invention object, the utility model has adopted following technical scheme:
Vacuum bag gas leak tester, comprise by vacuum detecting casing and case lid be tightly connected form and have at least one can transparent observing part sensing chamber and the pumped vacuum systems that can vacuumize sensing chamber, described case lid can be opened with respect to vacuum detecting casing, in vacuum detecting casing, water is housed, case lid below is provided with the pressing plate for vacuum bag being pressed on to water, and described case lid is provided with vacuum release valve and the pressure vacuum gauge of communication with detection chamber respectively; Described pumped vacuum systems comprises vacuum generator and vacuum-pumping pipeline system, and vacuum generator, by vacuum-pumping pipeline system connectivity sensing chamber, is also provided with the hand valve of it being controlled to start and stop on vacuum generator.
Further, described vacuum generator is arranged on sensing chamber below, and vacuum-pumping pipeline system is connected into sensing chamber from case lid top.
As preferably, described case lid one lateral edges, by being connected to vacuum detecting casing one lateral edges at the articulated elements of certain angle location after digging, detects easy to operate.
As preferably, described vacuum detecting casing and case lid are respectively transparent casing and transparent case lid, and further, described pressing plate is transparent pressing plate.Whether the sensing chamber forming is like this structure of all-transparent, be convenient to observe and decide and leak gas.
Adopted the vacuum bag gas leak tester of technique scheme, used the device that sensing chamber is vacuumized instead vacuum generator, utilized this vacuum generator high velocity jet pressurized air, formed jet at nozzle exit, generation is entrainmented mobile.Under the effect of entrainmenting, nozzle exit ambient air is constantly sucked away, make Pressure Drop in adsorbent chamber to atmospheric pressure, form certain vacuum degree, thereby realize, casing is vacuumized.Owing to not needing vacuum pump to obtain vacuum, thus when work noise low and unlike vacuum pump, produce exhaust emission, practical.
And detection case covers and is provided with vacuum release valve and pressure vacuum gauge, on vacuum generator, be provided with the hand valve of it being controlled to start and stop, therefore, when operation, pack vacuum bag into and close case lid sealed vacuum and detect casing, more manually opened vacuum generator vacuumizes, until pressure vacuum gauge is shown as spendable negative pressure, complete after detection, open vacuum release valve, opening box covers repetitive operation, visible, this vacuum bag gas leak tester detects operation and uses also more convenient.On the contrary, adopt vacuum pump, at all need not pressure vacuum gauge, it is too low that it is easily taken out vacuum tightness, and not only energy consumption strong noise is large as mentioned above, and operating speed is slow.
