2, when bubble eject mouth the setting is in coping of coal tub wall, sealed or when blocking pluvial board upper part, lasher board height should not be less than the bubble of storage tank of mechanical and sealed way 0.3m, and should 0.1m; of tower above sealing ring is soft lasher board height should not be less than the bubble of sealed way storage tank 0.9m. Set Gu to block pluvial board bottom in the metal when mouth of bubble eject when, bubble lasher board height should not be less than 0.3m.
3, measure according to the experiment, when rising at the beginning of fire, flue gas is 0.3m/s to diffusing speed in water square.
4, electromotor should be installed go up in the baseplate that does not light material to be made, put apart answers to be apart from the passageway that is not less than 1m between the foundation of electromotor baseplate and building or other equipment. Between electromotor and wall of moisture in the soil, or when the electromotor a side of the furnish that become a kind already had a channel, the only space of another side should not be less than 0.3m.
5, the protective height of shower nozzle and protective radius, should accord with following regulation: The greatest protection shoulds not be highly be more than 6.5m; the least protection should not be less than 0.3m highly.
6, the axes of beam of light of detector is 0.3m ～ 1.0m to the vertical distance appropriate of ceiling, the height that be apart from the ground is unfavorable exceed 20m.
7, observe to facilitate and accurate measure li of pressure value, pressure watch and the distance that the entrance that balances type scale to mix device is in are not more than 0.3m.
Below general feeling , the end taking energy of life that should assure to be apart from generator of of tall diploid bubble is less than or be equal to 0.3m place to do not have keep out content.
The distance that mixed liquor of the bubble on storage tank establishs the rubiginous broken bits that provides lower end setting to sweep mouth and storage tank foundation or area is 0.3m ～ 0.5m commonly.
8, bubble gush drenchs conduit is raised, the distance between hanger and bubble shower nozzle cannot be less than 0.3m.
9, workshop and try (solid) the electrical outlet of check room installs height to be apart from the ground to not be less than 0.3m.
10, the safety between illumination luminaries and combustible is apart from common lamps and lanterns to should not be less than 0.3m.
11, under 3KW the following portable type electric heat implement should put on the workbench that does not light material to make, with all round the distance that combustible should maintain 0.3m above.
12, air conditioning appliance should be not installed in can light a structure, its equipment and all round the distance of combustible should not be less than 0.3m.
300mm
1, the basic practice that prevents liquid shedding to come loose has two kinds: It is in the bucket hole of outfit storehouse door is in build to overflow slope, it is 150mm ～ 300mm; high commonly 2 it is the door bank that builds height to be 150mm ～ 300mm in storehouse doorway build by laying bricks or stones, fill sandy soil to form free slope in door bank both sides again, facilitate assemble and unassemble.
2, piece brake a powerful person and check valve should be installed on conduit. When DN ≥ 300mm, appropriate employs a powerful person of dynamoelectric or hydraulic brake.
3, should be when the shower nozzle of Li of lower part cloth of bridge or other fraise, the distance between shower nozzle and roof must not be more than 300mm.
Body of the wall outside becoming uses the level that use B2 when insulation material, whether doesn't the examination light the tape of segregation of horizontal fire prevention that material makes every layers along floor place setting, the setting that segregation takes must not be less than 300mm highly.
4, the caliber inside fire hose: Internal diameter 25mm, 50mm, 65mm, 80mm, 100mm, 125mm, 150mm, 300mm.
5, use signal a powerful person and current indicator pilot are automatic at the same time sprinkler system, signal a powerful person installs the conduit before current indicator to go up, do not be less than 300mm with the distance between current indicator.
6, fluid sealant ply highlights fire prevention to seal a systematic face to should not be less than 13mm, seal after finishing, sealing a layer on two side cable, besmear brushs fire retardant coating, length 300mm.
7, grating is fiber-optic the monitoring area of every grating and protective radius should accord with heat fire detector the monitoring area of dot heat fire detector and protective radius requirement, fiber-optic grating feeling is lukewarm paragraph radius of bend should be more than 300mm.
8, common lamps and lanterns and tinderbox distance are unfavorable at 300mm.
9, ultrasonic flows most plan sensor uses V means and Z means installation commonly, normally the circumstance falls, when tubal diameter is less than 300mm, use V means installation.
Old pass the time in a leisurely way reminds everybody here, everybody should note a few special terms when remember, for example " must not, do not answer, unfavorable, cannot, should not " , the meaning that these words convey is not identical, must understand among them meaning, go remembering again!
