Description
Technical field
The invention belongs to diesel engine air inlet system fields, more particularly, to a kind of diesel engine air inlet system Rapid water drain valve.
Background technique
For marine diesel, since air humidity is big, into certain water for containing of air of diesel engine air inlet system
Point.When diesel engine works normally, this part water is seldom, enters after cylinder by thermal evaporation with air-flow with being discharged.But
After diesel engine stop, with the reduction of parts and components of diesel engine temperature, the moisture in gas handling system in air can condense and assemble
In air inlet pipe.If, if this part water is not processed, will be brought into cylinder by air-flow when diesel engine works again, one
Aspect will cause the performance issues such as diesel engine power declines and rotary speed unstabilization is fixed, and components in gas handling system can on the other hand sent out
It gets rusty and loses and damage, cause the generation of diesel engine more major break down.Therefore, how to be timely and effectively discharged solidifying in air inlet pipe
Bearing water is urgent problem.
In the prior art, no matter manual water drain or automatic bleeder are used, such device is largely equipped with
Spring structure, not only structure is complicated, and is easy failure using rear spring for a long time, and not only function is lost, and has an effect on diesel engine
Energy.In addition, the automatic drain valve for the threshold switch that discharges water is realized by the pressure in gas handling system, it is possible in low engine speed operating condition
Can there are problems that gas leakage.
Such as application No. is 201310471940.4 patent applications to disclose a kind of engine aspirating system and its automatic
Drain valve, and application No. is 201820042772.5 to disclose a kind of intercooler automatic drain valve, is by gas handling system
Pressure realize the threshold switch that discharges water.But engine just started or the low work condition state of low speed under, in gas handling system pressure compared with
Low, being likely to result in drain valve can not completely close, so that gas handling system gas leakage.Engine itself is under the low work condition state of low speed
For air inflow with regard to too low, engine performance is poor, if gas leakage occurs again, will cause engine performance and further deteriorates.
