Description
Technical field
The present invention relates to a kind of leakage detection apparatus, particularly relate to the device that a kind of stuffing pressure and monitoring leakage are pressed.
Background technology
Air purifier (claiming air cleaner, air cleaner again) is meant and can adsorbs, decomposes or transform various air pollutants (generally comprising finishing pollution, bacterium, anaphylactogen of dust, pollen, peculiar smell, formaldehyde and so on etc.); Effectively improve the product of air cleanliness; Be main with family expenses and the commercial air purifier of removing room air pollution at present, and water dish is particularly important to the impermeability of air purifier in the air purifier.
In order to guarantee the impermeability of water dish in the air purifier, need that water dish is charged into air and carry out airtight test.What use in the prior art is that precision regulator is regulated air pressure value, but its air pressure that charges into is unstable, causes the airtight test result of water dish unreliable.
Summary of the invention
Technical matters to be solved by this invention provides a kind of stuffing pressure and the device of pressing is leaked in monitoring, can accurately check the impermeability of kettle water dish.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of stuffing pressure and monitoring to leak the device of pressing; Comprise the base, compressed air source and the pressure measuring unit that are used to place kettle; Said compressed air source links to each other with kettle, and said pressure measuring unit is used to measure the air pressure of kettle; Also be provided with decompression valve, mechanical type decompression regulating device and digital-code type decompression regulating device between said compressed air source and the kettle successively.
Said pressure measuring unit also links to each other with the defective products lamp with the non-defective unit lamp respectively; The pressure that said pressure measuring unit is measured is then turned on the non-defective unit lamp, otherwise is turned on the defective products lamp during more than or equal to threshold value.
Said pressure measuring unit also links to each other with hummer, when the defective products lamp is opened, starts buzzer warning.
Said base links to each other with cylinder, and said cylinder is used to regulate the height of base.
Said pressure measuring unit is installed on the apparatus for adjusting position of being made up of first slide bar, second slide bar and inflator cylinder; Said pressure measuring unit is fixed on the inflator cylinder, and the inflator cylinder is installed on first slide bar, and first slide bar is installed on second slide bar.
Said mechanical type decompression regulating device also connects with the mechanical compression epiphase.
Said digital decompression regulating device also links to each other with the digital pressure display.
Beneficial effect
Owing to adopted above-mentioned technical scheme; The present invention compared with prior art has following advantage and good effect: it is simple that air of the present invention charges into mode, in inflation, can carry out trial inspection one time to the impermeability of water dish; Get rid of the article of leakage, improve monitoring efficient.The present invention adopts the digital-code type regulating device that air pressure is regulated, and makes the air pressure that charges into more stable, has guaranteed that the airtight test result is more reliable.

Fig. 2 is a circuit block diagram of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present invention relates to a kind of stuffing pressure and the device of pressing is leaked in monitoring; As depicted in figs. 1 and 2; Comprise the base 1, compressed air source 2 and the pressure measuring unit 3 that are used to place kettle, wherein compressed air source 2 is positioned at the below of base 1, and pressure measuring unit 3 is positioned at the top of base 1.Base 1 has cylinder 10, and cylinder 10 can be used to regulate the height of base 1, so that it adapts to the kettle of different sizes.Pressure measuring unit 3 is installed on the apparatus for adjusting position of being made up of first slide bar 11, second slide bar 12 and inflator cylinder 13; Said pressure measuring unit 3 is fixed on the inflator cylinder 13; Inflator cylinder 13 is installed on first slide bar 11, and first slide bar 11 is installed on second slide bar 12, and inflator cylinder 13 can carry out longitudinal sliding motion along first slide bar 11; First slide bar 11 can laterally slide along second slide bar 12, so can make pressure measuring unit 3 can detect the air pressure in the kettle of optional position.
Said compressed air source 2 links to each other with kettle through pipeline, only need trample foot-operated gas-filled switching tube during use, makes air charge into kettle and gets final product.Pipeline between said compressed air source 2 and the kettle also is provided with decompression valve 4, mechanical type decompression regulating device 5 and digital-code type decompression regulating device 6 successively.Pressurized air eases down to the air pressure of setting through decompression valve 4; Lower air pressure through the mechanical type decompression regulating device 5 that pre-sets force value again; Reduce pressure once more through pre-setting the digital decompression of force value regulating device 6 again, will fill into through the air of three decompressions in the water dish that needs to detect then.In order to know that the value set of whether reducing pressure to links to each other the mechanical type regulating device 5 that reduces pressure usually with mechanical compression table 14; Can clearly show force value through mechanical compression table 14; The number regulating device 6 that reduces pressure is also linked to each other with digital pressure display 15, can know the force value of the air that charges into kettle at last through digital pressure display 15.As shown in Figure 2; What compressed air source 2 was exported is the pressurized air of 3MPa; This pressurized air is through becoming the pressurized air of 0.6MPa behind the decompression valve 4; Again through becoming the pressurized air of 0.1MPa after the mechanical type decompression regulating device 5, at last through becoming the pressurized air of 15KPa after the digital-code type decompression regulating device 6.
Be not difficult to find that it is simple that air of the present invention charges into mode, in inflation, can carry out trial inspection one time to the impermeability of water dish, gets rid of the article of leakage, improves and monitor efficient.The present invention adopts the digital-code type regulating device that air pressure is regulated, and makes the air pressure that charges into more stable, has guaranteed that the airtight test result is more reliable.
