Description
Technical field
The utility model relates to efficient air port, a kind of toilet counting leakage detection apparatus.
Background technology
In recent years; New edition " GMP " (GMP) is put into effect; Various aspects to the toilet are all had higher requirement; Leak detection to efficient air port, toilet has also improved requirement, standard GB/T 25915-2010 adopting by equation international standards ISO14644 (toilet and associated controlled environment), wherein ISO14644-3 the 3rd part detection method; For the leak detection of efficient air port, toilet clear and definite leak hunting method and specific requirement are arranged, this just makes the efficient air port standard more of hunting leak.
Summary of the invention
The utility model purpose is: the utility model is developed design under above-mentioned technical background, has proposed efficient air port, a kind of toilet counting leakage detection apparatus, and whether the filter that it can detect efficient air port, toilet well has seepage.
The technical scheme of the utility model is: efficient air port, described toilet counting leakage detection apparatus; Comprise aerosol generator, the gas outlet of this aerosol generator is connected with air box through flexible pipe, is furnished with blower fan in the air box; The air outlet of air box is communicated with the air outlet of toilet through airduct; Be furnished with high efficiency particulate air filter in the said air outlet, the upper reaches of high efficiency particulate air filter link to each other with diluter through flexible pipe, and diluter links to each other with the counting leak detector through flexible pipe again; The arranged downstream of high efficiency particulate air filter has manual sampling probe, and this manual sampling probe also links to each other with said counting leak detector with holding wire through flexible pipe.
As preferably, the external diameter that is connected in the flexible pipe between the air inlet of gas outlet and air box of aerosol generator is 29mm.
As preferably, being connected in the upper reaches of high efficiency particulate air filter and the external diameter of the flexible pipe between the diluter is 15mm.
As preferably, the external diameter that is connected in the flexible pipe between diluter and the counting leak detector is 8mm.
As preferably, the external diameter that is connected in the flexible pipe between manual sampling probe and the counting leak detector is 8mm.
The utility model has the advantages that: the utility model provides efficient air port, a kind of toilet counting leakage detection apparatus, and its principle and structure and correlation technique data meet the requirement of ISO14644-3 standard to toilet's efficient air port leak detection.It is that dirt dirt source is sent out at the upper reaches with liquid aerosol (decanedioic acid two (2-ethylhexyl) ester); Detect high efficiency particulate air filter upper reaches particle concentration through the counting leak detector; The formula that provides through the ISO14644-3 standard again calculates high efficiency particulate air filter downstream leak source value, uses manual sampling probe to be connected with the counting leak detector then high efficiency particulate air filter downstream population is surveyed; Comparison through leak source value and measured value; Judge whether this high efficiency particulate air filter has seepage, but and field print leak detection data, very convenient.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model embodiment;
Wherein: the 1-aerosol generator, the 2-air box, the 3-blower fan, the 4-airduct, the 5-air outlet, 6 toilets, the 7-diluter, the manual sampling probe of 8-, 9-counts leak detector, 10-high efficiency particulate air filter.
The specific embodiment
As shown in Figure 1, efficient air port, the toilet of present embodiment counting leakage detection apparatus comprises aerosol generator 1.The gas outlet of this aerosol generator is that the flexible pipe of 29mm is connected with air box 2 through external diameter, is furnished with blower fan 3 in the air box 2.The air outlet of air box 2 is communicated with the air outlet 5 of toilet 6 through airduct 4.Be furnished with high efficiency particulate air filter 10 in the said air outlet 5, the upper reaches of high efficiency particulate air filter 10 (a place among the figure) is that the flexible pipe of 15mm links to each other with diluter 7 through external diameter, diluter 7 again through external diameter be 8mm flexible pipe with the counting leak detector 9 link to each other.The downstream of high efficiency particulate air filter 10 (b place among the figure) are furnished with manual sampling probe 8, and this manual sampling probe is that the flexible pipe of 8mm also links to each other with said counting leak detector 9 through holding wire and external diameter.
The operation principle of present embodiment is: present embodiment is by aerosol generator 1; With liquid aerosol (decanedioic acid two (2-ethylhexyl) ester) is that dirt dirt source is sent out at the upper reaches, detects high efficiency particulate air filter 10 upper reaches particle concentrations, the formula that provides through the ISO14644-3 standard again through counting leak detector 9; Calculate high efficiency particulate air filter 10 downstream leak source values; Use manual sampling probe 8 to be connected then, high efficiency particulate air filter 10 downstream populations are surveyed, through the comparison of leak source value and measured value with counting leak detector 9; Judge whether this high efficiency particulate air filter 10 has seepage, very convenient.
Certainly, the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets people can understand the utility model and implements according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
