Description
Technical field
Passenger train aeration device for subsequent use, relates to train field of ventilation.
Background technology
China railways network spreads all over the country, and railway transport of passengers is still main stream traffic instrument.For a long time, railway transport of passengers passenger flow volume is large, and particularly in the spring transportation summer transportation phase, common attending a banquet is usually full or overcrowding delivery, and crowded passenger is in narrow compartment, and air quality can decline.Regulating for utilizing natural wind makes fresh air enter compartment, the Chinese patent CN202006797U patent of prior art, due to its fresh wind tube 1 and the version of exhaust duct 2, two-way confession 10 place's bending, the pressure reduction between fresh wind tube 1 and exhaust duct 2, by the local resistance loss of 10 bendings, almost approach exhaustion, ventilation effect is very poor, unless fresh wind tube 1 is enough large with the pipe diameter of exhaust duct 2, thus, vehicle operating resistance will increase greatly.By also finding out in its specific embodiment that " be set as by the cross sectional dimensions of exhaust duct (1): 800mm × 300mm, the cross sectional dimensions of fresh wind tube (2) is set as: 500mm × 150mm." will higher than roof 1200 ~ 1400mm, this has highly exceeded the railway clearance standard of China and world's most countries, serious harm traffic safety.According to the regulation of " People's Republic of China's railway technology code " accompanying drawing 2, the height in compartment is less than 4800mm from railroad track end face to vehicle roof equipment vertex.The height of the main flow passenger vehicle 25G type vehicle that China railways is current is 4433mm, if use the height of this equipment vehicle will more than 5633mm, this will overturn the rolling stock clearance standard of China, to cannot implement in China and world's most countries at all, such technical scheme, redesign existing vehicle (if change height of car comprehensively, entire vehicle intensity will be affected, must all redesign), improve the height of railway auxiliary building, as: tunnel, bridge, platform canopy, contact system (electric locomotive high voltage supply line) and garage door etc.In addition, the fresh-air ventilation mouth " fresh wind tube 1 " in CN202006797U is all the fresh wind tube in face of wind, and inlet-duct area determines ventilation volume, and the resistance in train driving like this will strengthen greatly, and train entirety must redesign.In other words, to increase the air interchanger as described in CN202006797U patent on existing train, the redesign of the vehicle in using repacking must be run by existing.
The Chinese patent of prior art: CN2811045Y, is only applicable to automobile, is not suitable for the two-way train started.

Principles of Chemical Engineering
The coefficient of local resistance of table 1-2 pipe fitting and valve member and equivalent length value (for turbulent flow)
3, negative pressure ventilation pipe 2, positive airway pressure pipe 4 are corrosion-resistant steel smooth pipe.From fluid mechanics, friction coefficient λ is the important parameter of the resistance to flow of fluid, and fluid is when transition flow or turbulent flow:
The impact of the resistance of visible relative roughness fluid flow.
4, Top Skin is equipped with automatic watertight door assembly 10 for 15 times, can close negative pressure ventilation pipe 2 and positive airway pressure pipe 4 time rainy.
5, " negative pressure ventilation pipe 2, positive airway pressure pipe 4 are all at train top " is due to the passenger train aeration device for subsequent use of the application, for stand-by system during power supply trouble, when opening without air-conditioning in car be no matter so due to sunshine or personnel crowded, cause temperature in compartment higher than outside compartment at last, foul smell rises, ozone temperature, lower than the temperature in compartment, therefore enters compartment and flows downward, reach the effect of full compartment fresh air ventilation.
6, negative pressure valve 1 is 60 ~ 100mm higher than Top Skin 15.Lower than Air conditioning unit, after therefore increasing the device of the application, the height overall of vehicle can not be made to increase, guarantee driving safety.
7, simple in structure and low in cost.
