Gas cap and labyrinth bolt；Oil gas pipeline is formed on the side wall of babinet；The lower end outlet of oil gas pipeline is below pasta；Oil gas
Dust-proof abat-vent is bolted with the upper end outlet of pipeline；The lower end import of dust-proof abat-vent is provided with anti-dust filter mesh；Babinet
Labyrinth bolt is bolted with lateral wall；Labyrinth bolt level crosses oil gas pipeline and oil gas pipeline is divided into two up and down；Fan
Oil gas is formed on the right side of palace bolt to pass through hole；Oil gas pass through hole left side side wall on the upside of extend upward through and be provided with exhaust
Hole, downside are downward through being provided with outage；Exhausting-gas hole is connected with the top of oil gas pipeline；The lower part of outage and oil gas pipeline
Connection；The pass through right end import in hole of oil gas is higher than pasta.
As the preferred of above-mentioned technical proposal, the upper end air outlet of dust-proof abat-vent is located on the lower face of cap body.
As the preferred of above-mentioned technical proposal, the right side of labyrinth bolt is concordant with the madial wall of babinet.
As the preferred of above-mentioned technical proposal, connected between the top of exhausting-gas hole and oil gas pipeline by the pipeline of bending.
As the preferred of above-mentioned technical proposal, connected between the lower part of outage and oil gas pipeline by the pipeline of bending.
The beneficial effects of the utility model are：The presence of anti-dust filter mesh ensure that filtering suction while breathing is smooth
Air；The internal structure of labyrinth bolt forms labyrinth with oil gas pipeline, ensure that oil gas not directly enters abat-vent, and complete
Olefiant gas separates；It ensure that the balance of inner and outer air pressure.
Brief description of the drawings
