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 air-tightness detection device is one of the important component in flue gas processing device, mainly by power
Executive component, valve body, valve plate and valve rod composition, valve plate is doubling plate, and valve rod is fixed in doubling plate, and one end and power execute
Element connection, the other end are rotatably installed in valve body.Due to leakproofness performance of the valve plate between doubling plate, with valve body
It is bad, the untreated flue gas evolution in part is still had, the treatment effeciency of flue gas processing device is caused to reduce.To solve this skill
Art problem at present mainly further seals valve by the way of hermetic seal, due to the accumulation of accessory error, causes each
The pressure value of gas needed for a valve is all different, so valve needs to carry out pneumatic sealing test before factory, however at present on the market
Pneumatic sealing test device all costly, and is not suitable for valve detection yet, so needing one deck valve door air-leakage test of design
Device.
