Abstract
The utility model relates to a toilet especially relates to the indoor pressure adjustment assembly in toilet. An invariable device of indoor pressure differential in toilet, the toilet is equipped with the exhaust pipe of supply -air outlet, return air inlet and inside plant, the exhaust pipe of equipment is divideing into indoor pipe and outdoor pipe, outdoor tub of one end run -on fan group, and the other end penetrates indoorly, and its pipe diameter is greater than the pipe diameter of indoor pipe, and indoor pipe end portion inserts outdoor intraductally. Through the utility model discloses can reach manufacturing equipment open or the block state under, room pressure differential is unchangeable.
Description
Technical field
The utility model relates to toilet, particularly relates to a kind of toilet room pressure adjusting device.
Background technology
Equipment is had to need to make exhaust duct in electrical type, pharmaceutical environment purification, to guarantee to take away too much heat and off-air; A large amount of wind will be discharged in such room, form the balance of air-supply=air draft+return air, because according to different production statuses, as produced and not producing, and public one group of exhaust blower, therefore can not have because of equipment or cause the out of control of room air balance without air draft, room air-supply > return air+air draft will be caused, cause pressure reduction to change, form hidden danger of quality, easily cause production accident.
Summary of the invention
The utility model is intended to the defect overcoming prior art, provides the constant device of the indoor pressure reduction in a kind of toilet.The utility model can reach equipment air draft can keep pressure difference no change in stopping with under running two states.
In order to solve the problems of the technologies described above, the constant device of the indoor pressure reduction in a kind of toilet, described toilet is provided with the exhaust duct of air outlet, return air inlet and indoor equipment, the exhaust duct of described equipment is being divided into indoor pipe and outdoor pipe, outdoor pipe one end connects air draft unit, the other end penetrates indoor, and its caliber is greater than the caliber of indoor pipe, and indoor pipe end is inserted in outdoor pipe.
The constant device of the indoor pressure reduction in described toilet, described return air inlet leads to outdoor by the backwind tube being embedded in sandwich wall, and outdoor backwind tube is provided with control valve.
The constant device of the indoor pressure reduction in described toilet, the outdoor pipe of described exhaust duct connects air draft unit by a quantitative air-valve.
The utility model is determined according to layout design content, total air output, according to equipment exhaust blower air quantity determination equipment air quantity, the basic like this size can determining mother-son mouth rim of the mouth, area changes the size can determining female mouth, the basic like this size can determining mother-son mouth.Mother-son mouth effect, rim of the mouth is used for equipment air draft, when equipment air draft stops time, is completed the air draft in room, can guarantee the balance of room total blast volume like this by female mouth.
Concrete debugging; Determine the quantity of total air output according to layout design, the air draft quantity according to air draft unit determines the technical indicator of determining air quantity valve, the regulated quantity of upper and lower 20%.
Debugging under static state, process equipment air draft is not opened, and roof vent fan group is opened, and by air returning valve, is modulated to pressure reduction reasonable.Under process equipment air draft opening, air draft unit, ceaselessly under state, is observed differential pressure indicator change, then by air returning valve fine tuning, is finally found the equalization point of dynamic and static state two states.
Can reach process equipment under unlatching or halted state by the utility model, room pressure reduction is constant.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, the constant device of the indoor pressure reduction in a kind of toilet, described toilet 1 is provided with the exhaust duct of air outlet 2, return air inlet 3 and indoor equipment 4, the exhaust duct of described equipment is being divided into indoor pipe 51 and outdoor pipe 52, outdoor pipe one end connects air draft unit 6, the other end penetrates indoor, and its caliber is greater than the caliber of indoor pipe, and indoor pipe end is inserted in outdoor pipe.
Described return air inlet leads to outdoor by the backwind tube being embedded in sandwich wall 31, and outdoor backwind tube is provided with control valve 32.
The outdoor pipe of described exhaust duct connects air draft unit by a quantitative air-valve 53.
