Abstract
The invention relates to an air passage control system used for air braking automobiles, and particularly relates to an oil-water separator assembly which is used in the system and capable of filtrating water and oil, preventing frostbite and automatic transmission. The control system includes an air compressor, an air drier and an air reservoir, wherein the air compressed by the air compressor is processed by the air drier and then stored in the air reservoir. The control system is characterized in that the air compressed by the air compressor firstly passes through the oil-water separator for removing the liquid water as well as oil, oil gas and solid pollutants in the compressed air, and then enters the air drier. The control system has the advantages that the oil-water separator used in the system is guaranteed to remove oil, water and solid pollutants from the air compressor out of the system at the first moment, thereby ensuring the cleanness and the smoothness of the air passage, preventing the desiccant (molecular sieve) in the air drier from invalidation or shortened service life, further ensuring the cleanness and the dryness of the air passing through pipelines and braking elements, and greatly prolonging the service life of the braking elements and improving the security of the whole automobile.

The specific embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technical personnel of the same trade:
Shown in Fig. 1-5, label 1-21 represents respectively: air compressor 1, oil water separator 2, check valve 3, air dryer 4, check valve 5, pressure regulating valve 6, storage tank 7, admission port 8, chamber body 9, double-deck oil crosses filter core 10, blowback chamber 11, air extractor duct 12, control cock assembly 13, efflux mouthfuls 14, housing 20, adapter plate 21 are filtered in control mouthfuls 15, the fast plug 16 of waterproof, temperature controller 17, heating pole 18, body 19, oil.
A kind of connection mode that present embodiment is used for the automobile air-channel system as shown in Figure 1, air compressor 1 work is to whole air-channel system air feed, through oil water separator 2, water and oil with liquid state, oil gas and solid pollutant filter out, remove remaining moisture in the air through air dryer 4 again through the air after filtering, the air that comes out from air dryer 4 is kept at each several part use 7 li air feed roads of storage tank, storage tank is connected with a pressure regulating valve 6, when the pressure of storage tank 7 reaches the switch pressure that pressure regulating valve 6 regulates, gas can lead to air dryer 4 respectively by pressure regulating valve 6, oil water separator 2, the control mouth of air compressor 1, its control cock assembly is opened, and the oil water separator 2 of this moment is in the automatic oil draining state.When the air pressure in the storage tank 7 drops to 6 times passes of pressure regulating valve pressure, each parts comprises that the gas of the control mouth of air dryer 4, oil water separator 2, air compressor 1 discharges from pressure regulating valve 6, so air compressor 1, the control cock assembly of oil water separator 2, air dryer 4 is closed, this moment, air compressor 1 was started working, and entered second air feed circulation.
Present embodiment provide with antifreeze, from the oil water separator 2 of row function, comprise chamber body 9, this inner chamber 9 is used for collection and stays profit, foreign material etc.; An oil filters housing assembly and the compressed-air actuated chamber of fixed volume.Oil filter housing assembly by an oil filter housing 20, filter core 10 crossed by two-layer oil and an adapter plate 21 is formed, is used to filter profit and other solid impuritieies, this assembly is connected and fixed by adapter plate 21 and body 19.Blowback chamber 11, oil filter housing assembly and are connected to oil water separator 2 assemblies with the body 19 that control cock assembly 13 is housed.Control cock assembly 13 has two moving positions, two states of controlled filter oil and automatic oil draining.When valve module 13 then oil water separators in the closed position are in the oil strain state, oil water separator is in the oil extraction state when valve module 13 is shown in an open position then.On the body 19 defroster is housed.
The oil water separator 2 of present embodiment in the internal work principle in two stages of filter oil, water and automatic oil draining, water shown in Fig. 2,3.Oil water separator 2 comprises admission port 8, chamber body 9, double-deck oily filter core 10, blowback chamber 11, air extractor duct 12, control cock assembly 13, exhausr port 14, the control mouth 15 crossed.
Figure 2 shows that the filter oil stage, the air that comes out from air compressor enters in the chamber body 9 from admission port 8, and this moment, control cock assembly 13 was in closed condition because control mouth 15 does not have air pressure, air-flow is crossed filter core 10 from double-deck oil and is passed through, thereby filters greasy dirt, solid pollutant etc.After air after process is filtered passes through blowback chamber 11 again, discharge from air extractor duct 12.Through this process, airborne portion of water, greasy dirt, solid pollutant are filtered at oil and cross on the filter core 10, and in the chamber body 9.
Figure 3 shows that the automatic oil draining stage, this moment, this air pressure forced control cock assembly 13 to be shown in an open position because control mouth 15 has the air pressure of coming by pressure regulating valve 6.This moment, oil water separator 2 in-to-in air pressure were higher than external atmosphere pressure, so the air-flow double-deck oil of flowing through from blowback chamber 11 crosses filter core 10, flowed to the external worlds to chamber body 9 by effluxing mouthfuls 14.Be retained in oil and cross on the filter core 10 and water, greasy dirt, impurity in the chamber body 9 also are discharged into outside the oil water separator 2 with air-flow, thereby realize automatic oil draining, cross the self-cleaning processing of filter core.
Gas circuit is freezed when preventing that vehicle from exercising under low temperature environment, cause brake failure and produce safety misadventure and the defroster that adds as shown in Figure 4, this defroster adopts Temperature controlled heater, temperature booster is by the fast plug 16 of waterproof, temperature controller 17, heating pole 18 is formed, when temperature is low to moderate the temperature controller operating temperature, temperature booster is started working, the anti-timely and effectively locking system phenomenon of freezing to death, during work when temperature is lower than temperature controller 17 and opens temperature, temperature controller 17 switchs on, this moment, heating pole 18 had electric current to pass through, thereby reached the purpose of heated oil water separator, prevented to freeze.
