The marine exhaust pollution of fuel is also increasingly severe.Studies have shown that 30% being come from the oxides of nitrogen gas that discharges every year of the whole world
In marine ships, oxysulfide accounts for the 5% of world's total emission volumn.Marine exhaust has arrived the pollution of atmosphere and cannot be neglected
Stage, especially in the sea area that the course lines such as harbour and straits are intensive and ship flow is big, the exhaust gas of ship discharge even at
For the primary pollution source of this area.International Maritime Organization requires each marine ship to be both needed to be equipped with flue gas processing device, ship
The flue gas of discharge can just discharge after desulfurizing and purifying is handled.
Heavy caliber gas fume valve is one of the important component in flue gas processing device, mainly by valve body, valve plate and valve rod group
At still having part untreated flue gas ease since leakproofness performance of the valve plate between doubling plate, with valve body is bad
Out, leading to the treatment effeciency of flue gas processing device reduces.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of heavy caliber gas fume valve of valve plate good seal performance,
To realize the purpose of the evolution of flue gas zero.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows:
Heavy-caliber high-temperature gas fume valve, including valve body and the double-deck valve plate, the bilayer valve plate is located in valve channel, and leads to
The valve rod for crossing both ends is installed in rotation in valve body, is provided at the corresponding double-deck valve plate outside the valve body and is led to valve body
The air inlet pipe of road connection, the air inlet pipe are connect with compressed gas source, valve seat are formed in valve channel, the valve seat corresponds to valve plate
One end is provided with hollow seal pad, is equipped with pressure sensor in the hollow seal pad.The plate face of valve plate is pressed on gasket,
After the pressure that pressure sensor detects reaches systemic presupposition range, compressed gas source is automatically opened through air inlet pipe to double beat valve
The gas that pressure is greater than flue internal pressure is blowed in plate, such as: the pressure of flue is 2-3kpa, and compressed gas source is blown
The compressed gas of 5kpa is sent, these gases form sealing air film between valve plate and valve body.
The beneficial effects of the utility model are: compressed gas source is automatically opened blows at once into valve in the instant of valve plate
Hermetic seal is carried out, zero evolution of flue gas is realized.
