Abstract
The invention discloses the gas collecting apparatus tested for indoor formaldehyde content, including vacuum tank, also include the attachment means being arranged on vacuum tank, the vacuum tank is also connected by check valve with pressure vessel, and the guiding of the check valve points to vacuum tank by pressure vessel.When gathering gas, the gas near collection air valve, automatic extraction is opened, collection air valve is closed after the completion of gas collecting, when needing to use the gas in vacuum tank, open check valve, pressure vessel is discharged the gas in vacuum tank by vacuum tank pressure release.It is an advantage of the invention that：Pass through vacuum plant Quick Acquisition gas, it is not necessary to stopped in gas collecting environment more long；Gas collecting directive property is obvious.
Description
Technical field
The present invention relates to a kind of wood working tool, and in particular to the gas collecting apparatus tested for indoor formaldehyde content.
Background technology
Combine what is promulgated by the Ministry of Public Health, State Environmental Protection Administration and State Administration for Quality Supervision and Inspection and Quarantine《GB/T18883-
2002 Indoor Air Quality standards》The basic standard of substantially one healthy residential environment, to building developer, finishing business,
Furniture dealer does not obligate power.Promulgated by the Ministry of Construction, State Administration for Quality Supervision and Inspection and Quarantine's joint《Civil buildings work
Journey indoor environmental pollution controls specification》GB50325-2001 (2006 editions) is then in the control of civil building engineering indoor environmental pollution
Aspect, has the testing conditions of the testing conditions ratio of enforceable acceptance of work standard seriously loose builder and finishing business,
Although the former pollutant concentration limit value is slightly less than the latter, the condition closed the doors and windows before detection only has 1 hour, and the latter is 12
Hour.Therefore, the end user in vast house is pointed out, by the civil building engineering and interior decoration engineering of standard final acceptance of construction
House, be not equal to the adequate condition for reaching people's health in residential environment.If introducing furniture in house, no matter the new home or old room,
IAQ is likely to further decline, the IAQ detection carried out of considering for life and health, is only measurement
Whether house meets the fundamental basis of healthy residential environment standard.
Existing formaldehyde testing equipment generally requires operating personnel's handheld device and detected in environment to be measured, during one-time detection
Between it is longer, be unfavorable for the health of testing staff.
The content of the invention
The technical problems to be solved by the invention are that existing formaldehyde testing equipment generally requires operating personnel's handheld device
Detected in environment to be measured, one detection period is longer, is unfavorable for the health of testing staff, it is therefore intended that provide for indoor first
The gas collecting apparatus of aldehyde test, solves existing formaldehyde testing equipment and generally requires operating personnel's handheld device in environment to be measured
Middle detection, one detection period is longer, the problem of being unfavorable for the health of testing staff.
The present invention is achieved through the following technical solutions：
The gas collecting apparatus tested for indoor formaldehyde content, including vacuum tank, in addition to be arranged on vacuum tank
Attachment means, the vacuum tank is also connected by check valve with pressure vessel, and the guiding of the check valve is referred to by pressure vessel
To vacuum tank.When gathering gas, the gas near collection air valve, automatic extraction is opened, collection is closed after the completion of gas collecting
Air valve, when needing to use the gas in vacuum tank, open check valve, pressure vessel is by vacuum tank pressure release, by vacuum
Gas discharge in container.
The attachment means include the valve of the interface that match with formaldehyde test device and setting in the interface.
The vacuum tank is also connected by collecting air valve with flexible pipe, and the collection air valve is used points to vacuum plant by flexible pipe
Check valve.It is easy to gather the gas of distant place by flexible pipe.
One end that the flexible pipe is not connected with vacuum plant is additionally provided with sharp mouth.The sensing in gas collecting region can be made
Property becomes apparent from.
Pressure vessel is located above vacuum tank when the gas collecting apparatus is used, and high-pressure helium is irrigated in pressure vessel.Make
Be conducive to the data analysis in later stage with inert gas.
The present invention compared with prior art, has the following advantages and advantages：
1st, the gas collecting apparatus that the present invention is tested for indoor formaldehyde content, by vacuum plant Quick Acquisition gas, is not required to
To be stopped in gas collecting environment more long；
2nd, the gas collecting apparatus that the present invention is tested for indoor formaldehyde content, gas collecting directive property is obvious.
