Abstract
The invention discloses a waterproof and leakage detecting device for machine benches. The machine benches comprise air inlets. The device comprises a gas tank, gas-guide tubes and a throttle valve, wherein the gas tank is provided with a gas outlet, and low-temperature gas is filled into the gas tank; one end of each gas-guide tube is connected with the gas outlet of the gas tank, and the other end of each gas-guide tube is connected with the air inlets of the machine benches; and the throttle valve is arranged on the gas-guide tubes to control the flowing pressure of the gas in the gas-guide tubes. Compared with the prior art, the waterproof and leakage detecting device for the machine benches has the advantages that the low-temperature gas is filled into the machine benches, so that air at the periphery is condensed to form white mist due to low temperature. If water leakage areas occur on the machine benches, the low-temperature gas can be leaked from the hole, and the air at the periphery forms the white mist, so that observers can discover easily, and the aims of the water prevention and leakage detection of the machine benches are fulfilled. A mode of performing the water prevention and leakage detection by observing the white mist is more accurate than a mode of performing tests by feeling and is clear, and work hours are saved.
Description
[technical field]
The present invention relates to a kind of board waterproof leakage detection apparatus, particularly relating to a kind of is the board waterproof leakage detection apparatus of IP65, IP67, IP68 for classification of waterproof.
[background technology]
IP grade (dustproof and waterproof), IP is the abbreviation of Ingress Protection, the IP grade is to allotrylic degree of protection for the electrical equipment shell, as: explosion-proof electric apparatus, water proof and dust proof electrical equipment, the source was the standard IEC 60529 of International Electrotechnical Commission, and this standard also was adopted to American National Standard in 2004.
In this standard, for the protection of electrical equipment shell to foreign matter, the form of IP grade is IPXX, and wherein XX is two arabic numeral, and the first reference numerals represents contact protection and exotic protection class, and the second reference numerals represents the waterproofing protection grade.
IP is that the world is used for assert that the code name IP grade of degree of protection is comprised of two numerals, and first digit represents to prevent dust; Second digit is by the expression waterproof, and its degree of protection of the larger expression of numeral is better.
Classification of waterproof (second X represents)--0: not protection; 1: water droplet splashes into shell without affecting 2: when shell tilts to 15 when spending, water droplet splashes into shell without impact; 3: water or rainwater from 60 degree corners to the shell without impact; 4: liquid is sprinkled by any direction and does not injure impact to shell; 5: water washes without any injury; 6: can be used for the environment in the cabin; 7: can anti-immersion (1m) 8 within the short time: for a long time immersion under certain pressure.
Advise notebook computer for the worker, board also has the waterproof requirement grade, at present to the test of these classification of waterproof, is to use positive pressure air from the air admission hole inflation of board, goes to seek the leak point with ear, dermal sensation again.
Yet, adopt aforesaid way to carry out the waterproof leak detection, the result with sensory test can vary with each individual on the one hand, and not only out of true also may mislead maintenance activity and cause the mistake of doing over again; On the other hand, owing to need to experience in the various piece of board, therefore detect to get up to waste man-hour.
In view of this, be necessary to develop a kind of board waterproof leakage detection apparatus in fact, to address the above problem.
[summary of the invention]
Therefore, the purpose of this invention is to provide a kind of board waterproof leakage detection apparatus, both avoided not high with the sensory test accuracy, avoid waste man-hour again.
In order to achieve the above object, board waterproof leakage detection apparatus provided by the invention, described board has air admission hole, and this device comprises:
Gas tank, it has the gas outlet, in the described gas tank cryogenic gas is housed;
Wireway, the one end connects the gas outlet of described gas tank, and the other end of described wireway connects the air admission hole of described board;
Throttling valve, it is located on the described wireway, controls gas flow pressure in the described wireway.
Optionally, the classification of waterproof that detects of described waterproof leakage detection apparatus is IP65, IP67 or IP68.
Optionally, described cryogenic gas is liquid carbon dioxide.
Optionally, described device also comprises an operator's console, and described board places on the described operator's console.
Optionally, described device also comprises translucent cover, is located at outside the described board.
Optionally, described translucent cover is the acrylic translucent cover.
Optionally, described device also has tensimeter, and it is corresponding to described throttling valve, and described tensimeter shows by after the described throttle valve control, the pressure of gas flow in the described wireway.
Optionally, described device is tested two boards simultaneously, and described wireway corresponds to two, and described throttling valve and described tensimeter also correspond to two.
Optionally, described board is advised class notebook computer board for the worker.
Compared to prior art, utilize board waterproof leakage detection apparatus of the present invention, adopt cryogenic gas to be filled with described board, because temperature is lower, can allows the ambient air condensation and form white mist.If there is the district that leaks on the board, then cryogenic gas can leak from hole, and ambient air forms white mist, and allows the observer be easy to find, thereby reaches the purpose of board waterproof leak detection.Because by observing the mode of white mist, it is more accurate to feel to test than employing, and very clear, saves man-hour.

[embodiment]
See also Fig. 1, Fig. 1 illustrates the board installation pre-structure synoptic diagram into board waterproof leakage detection apparatus of the present invention one preferred embodiment.
Board waterproof leakage detection apparatus provided by the invention, described board 100 has air admission hole 101, the classification of waterproof that the waterproof leakage detection apparatus of present embodiment detects is IP65, described board is advised class notebook computer board take the worker, and (temperature of its working environment can reach-20 ℃ as example, the type that has can reach-32 ℃), this device comprises:
Wireway 300, one end connect the gas outlet 201 of described gas tank 200, and the other end of described wireway 300 connects the air admission hole 101 of described board 100;
Wherein, described device can also comprise an operator's console 500, and described board 100 places on the described operator's console 500, makes things convenient for the user to operate.Described operator's console can have an accommodation space 500 times, in order to the described gas tank 200 of convenient placement.
