1, bypass valve area is large, and quantity is few, and the impact of single door on overall bypass flow is larger.
2, inlet air filter system orlop is all set to bypass valve, and pre-filtering weather cover quantity reduces, and inlet air filtration area also reduces thereupon, and intake resistance increases.
Model utility content
The purpose of this utility model is the technical problem existed to solve combustion engine inlet air filter system pre-filtering bypass valve, a kind of weather cover with counterweight type bypass valve is provided, the utility model is in order to overcome the shortcoming of traditional pre-filtering weather cover, take corresponding corrective measure pointedly, when weather cover inside and outside differential pressure reaches bypass pressure, the bypass valve that air-flow is carried through each weather cover enters filtration system, increases pre-filtering area simultaneously, reduces intake resistance.
To achieve these goals, the technical solution of the utility model is as follows: comprise integral frame, coarse filtration plate cross bar, coarse filtration plate, counterweight type bypass valve, bypass valve dunnage, cellular screen, coarse filtration plate baffle plate, coarse filtration plate montant, integral frame is by weather cover right sideboard, weather cover left sideboard, weather cover upper plate forms, cellular screen is installed in bottom, coarse filtration plate is evenly freely placed on cellular screen, coarse filtration plate is fixed by equally distributed two coarse filtration plate montants and a coarse filtration plate cross bar, coarse filtration plate cross bar relies on weather cover right sideboard and weather cover left sideboard to be supported on the top of coarse filtration plate, coarse filtration plate montant relies on weather cover upper plate and coarse filtration plate baffle plate to be supported on bottom coarse filtration plate, the two can freely be dismantled, be convenient to the replacing of coarse filtration plate, counterweight type bypass valve paired mounting is in bypass valve support plate upper surface, opening direction is inner towards weather cover, outside the direct communication chamber of bypass valve dunnage lower surface.
Cancel gas handling system bypass door structure bottom, will independently bypass valve be dispensed in single weather cover, gas handling system installs weather cover bottom additional, makes air-flow realize bypass in each weather cover.
Compared with prior art, this model utility technology has following beneficial effect:
1, bypass valve quantity increases, and single bypass valve is less on overall air inlet bypass impact.
