The guiding length of tube is 300mm.
One kind adds blue tank, including adds blue tank breather valve, described to add blue tank breather valve and add blue tank breather valve for described.
The beneficial effects of the utility model：What the utility model was provided adds blue tank breather valve, and its breather valve end cap has ventilation
Hole and guide pipe, add the gas in blue tank, without that under pressure, could discharge, and ensure to add blue tank internal pressure at any time
With external pressure dynamic balance.Breather valve end cap and ventilation valve body threaded connection, there is sealing gasket centre, there is preferable sealing
Effect, makes to be discharged to by conduit after filter element filtering from the gas in breather valve and adds outside blue tank, and dust is not easily accessible logical
It is simple in construction in air valve；The blue tank that adds of the utility model offer adds basket tank breather valve including above-mentioned, with corresponding technology effect
Really.
