Description
Technical field:
The present invention relates to diving dress technical field, in particular to a kind of diving takes device for detecting sealability.
Background technique:
During rescuing and survey under water, needs to rescue and survey crew need to dress diving dress, being opened with this prevents from diving under water
Shi Tiwen scatters and disappears too fast, causes to lose temperature, and can also protect diver from the injury of reef or harmful animal plant, diving dress point
For watertight suit and wet suit, wherein when wearing watertight suit, body completely cuts off with water completely, can according to water temperature condition
With inside sweater reinforce heat preservation.
Such as Chinese patent Authorization Notice No. are as follows: a kind of diving suit air-leakage test clamp system of CN107421873A, inspection
Device and detection method are surveyed, including gas pressure in diving suit is measured by air gauge component, when gas in the diving suit detected
Body pressure closes the first gate valve after reaching testing requirements air pressure, carries out full pressure test, and detection mode is more single；.
Such as Chinese patent Authorization Notice No. are as follows: a kind of external pressure direct pressure closing test device for air tightness of CN108151985A-, including
Within the preset testing time, data are carried out calculation processing and divided by 3 pressure sensor Pn data of record standard container
Analysis, can calculate the slip size of test piece, the slip of solution and the threshold value of setting are compared it can be concluded that most
Final inspection survey is as a result, this device can not simulate air-tightness problem under the pressure condition of deep-sea, and testing result accuracy is not high；
Such as Chinese patent Authorization Notice No. are as follows: the quick air-tightness precise testing device of CN108195519A- and test method, including
Air tightness testing machine structure is inflated to the inner cavity of workpiece, is carried out air tightness test by the gas-tight tester and is outputed test result,
Diving dress can not be protected when detection, be easy when detection to damage caused by diving dress；
Such as Chinese patent Authorization Notice No. are as follows: a kind of products air tightness detection device of CN207456710U-, including laminating mechanism can
To squeeze product so that product pressing is fixed in Ding Li mechanism, so as to carry out convenient for inflation mechanism to product
Inflation.Pushing mechanism makes inflation mechanism transverse shifting, and inflation mechanism can be obtained with official and seals up inflating port and is inflated.Work as production
After the completion of product inflation, product is allowed to carry out nature gas leakage, timer is to show the gas leakage time, if the gas leakage time is greater than technique requirement
Between, then illustrate that product meets air-tightness requirement, if when gas leakage department be less than technique want seeking time, illustrate that product does not meet air-tightness
It is required that detection mode is single, the air-tightness of diving dress under pressure and no pressure environment can not be detected, diving dress can not be detected
Sealing performance at various pressures is not easy to calculate the leakproofness under different depth seawater, reduces the multiplicity of detection data
Property, it not can guarantee the accuracy of testing result.
