Description
Technical field
The utility model is related to valve technology fields, and in particular to be used for the air dryer valve body of automobile.
Background technology
Air dryer is mainly used for automotive field, is the important component of vehicle power control system.It is air-dried
The function of device is the gas from air compressor to be dried, and the gas after drying is stored to gas receiver.Air
The drying of drier mainly utilize drier, if continue in the case that it is no it is regenerated use, drier is up to saturation
Lose dry function.Regenerated effect is ensuring that the service life of drier can persistently work.
At present there are two types of making drier obtain regenerated mode, one is external regeneration gas receivers, by valve come control pipe
The connection in road so that the gas in regeneration gas receiver carries out blowback to drier, and then realizes the regeneration of drier；It is another
Kind is that air dryer carries revived structure, induction system pressure change, to judge whether regeneration is completed；And by solenoid valve come
The connection of control pipeline and the flow direction of gas.The shortcomings that the first regeneration is：It needs to increase additional gas receiver, occupy
The space of vehicle increases cost；The shortcomings that second of regeneration is：It is also more and more with the system of gas due to being needed on vehicle,
Gas consumption is increasing, cause the system air pressure president of vehicle be not achieved the time drier air pressure or air pressure it is unstable, into
And cause not regenerate or regeneration effect is bad.
