13 cleanliness, avoids pollution object and drug occurs chemical reaction, causes drug is rotten even to fail.
The corresponding blow valve 31 of one wind processing unit, the size of the aperture by adjusting blow valve 31 are adjusted and are corresponded to
Air-conditioner set 21 be sent into the air quantity of corresponding air supply pipeline 22, that is, adjust the air output of corresponding subregion.
Specifically, the performance parameter of each air-conditioner set 21 is consistent, and the parameter of each air supply pipeline 22 is consistent, and each
The parameter of air return pipeline 23 is consistent.Under the conditions of each wind processing unit performance is consistent, a wind processing unit is corresponding to be sent
The aperture of air-valve 31 is big, then the air output of subregion corresponding with the wind processing unit is big；The corresponding air-supply of one wind processing unit
The aperture of valve 31 is small, then the air output of subregion corresponding with the wind processing unit is small.In the identical situation of each air return pipeline 23
Under, i.e., in the identical situation of return air amount, the air output of a subregion is greatly and the air output of another subregion is small, then and two points
There are pressure differences between area.
The high subregion of security protection grade is the region for generating harmful substance, such as produces subregion 43；The high subregion of security protection grade is also
Including the region being connected to external environment, such as stream of people's subregion 42 or logistics subregion 41, i.e. personnel or production material enter clean area
Region, since the region is connected to external environment, bacterium or dust particle in outside air are easy to be mixed into drug, cause
Drug is rotten.The low subregion of security protection grade is not generate the region of harmful substance directly or be not connected to directly with external environment
Region, such as corridor subregion 44.
Entire clean area is divided into multiple subregions, and the corresponding wind processing unit of a subregion according to security protection grade, is led to
The aperture for overregulating each blow valve 31, that is, can control the air output of each subregion, to control the pressure difference between each subregion.
The low subregion of the usual security protection grade subregion high relative to security protection grade is positive pressure, i.e. the air subregion flow direction low from security protection grade
The high subregion of security protection grade prevents the harmful substance diffusion in production subregion 43, can also prevent the stream of people point under airflow function
Outside air leakage in area 42 or logistics subregion 41.
The corresponding air inlet valve 32 in one toilet 13, the size of the aperture by adjusting air inlet valve 32 are adjusted corresponding
Air supply pipeline 22 is sent into the air quantity of corresponding toilet 13, that is, adjusts the air output of each toilet 13 in each subregion.
After the air output of each subregion determines, by adjusting the aperture of each air inlet valve 32 in a subregion, adjusting should
The air output of each toilet 13 in subregion.In the identical situation of air return pipeline 23, i.e., in the identical situation of return air amount,
The air output of one toilet 13 is greatly and the air output of another toilet 13 is small, and there are pressure differences between the toilet Ze Liangge 13.
For producing subregion 43, the high toilet 13 of security protection grade is the toilet 13 for directly generating harmful substance, is such as connect
Kind room, raw material weighing room are contained using proportioning room of volatile solvent etc. since above-mentioned toilet 13 generates harmful substance
The gas leakage of harmful substance easily causes large-scale safety accident to the external world；The low toilet 13 of security protection grade is not i.e. straight
The toilet 13 for raw harmful substance of practicing midwifery, such as packer's bay or vessel purge chamber.
For stream of people's subregion 42 or logistics subregion 41, the high toilet 13 of security protection grade includes and production subregion 43 or corridor
The toilet 13 that subregion 44 is connected, such as dressing room or material take off packer's bay, due to above-mentioned toilet 13 respectively with clean ring
Border is connected to external environment, and the gas containing pollutant is easy to leak to the external world, causes safety accident；The low cleaning of security protection grade
Room 13 is the toilet 13 being connected with external environment, such as changes shoes room or material temporary room.
Each subregion is divided into multiple toilets 13, and the corresponding air inlet valve in a toilet 13 according to security protection grade
32, by adjusting the aperture of each air inlet valve 32, that is, it can control the air output of each toilet 13, to control each toilet
Pressure difference between 13.The toilet 13 high relative to security protection grade of the low toilet 13 of usual security protection grade is positive pressure, i.e. air
The toilet 13 low from security protection grade flows to the high toilet 13 of security protection grade and prevents in toilet 13 under airflow function
Harmful substance leaks to the external world.
