Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1 to 3, the utility model provides a crankcase permeability cell with blowdown function, including permeability cell body 1, the welding of one end top of permeability cell body 1 has connecting pipe 2, and a welding that permeability cell body 1 was kept away from to connecting pipe 2 is equipped with conveyer pipe 3, and permeability cell body 1 is parallel to each other with conveyer pipe 3's position, and the bottom spiro union of conveyer pipe 3 has water valve 4, and the bottom welding of water valve 4 has takeover 5, and the front surface of water valve 4 rotates and is connected with steering wheel 6.

In this example, when using permeability cell body 1 on the ship, make the takeover 5 of water valve 4 bottom pass through hose connection to dirty oil tank, when moisture and foreign matter from getting into permeability cell body 1, can open water valve 4 through steering wheel 6, make water valve 4 keep normally open state, then when outside moisture and foreign matter flow into conveyer pipe 3 inside, moisture and foreign matter can be under the effect of gravity from water valve 4 department drainage to dirty oil tank department, through inside can avoiding outside moisture and foreign matter to get into the crankcase like this, guarantee the normal use of crankcase.
