It should be noted that in practical operation, usually using drainpipe 17 from straight stream nozzle to emergency drainage device
Interior injection water, this water that may result in into water sealed tank 18 bottom carries a small amount of oil, in order to not allow oil level in water sealed tank 18,
According to knowhow, the oil being located in water sealed tank 18 should be floated on upper in water sealed tank 18 the static 10min of emergency drainage device
Portion, equally, also has minimal amount of oil to float on the top of drainpipe 17, when sealing the bottom of recovery device arrival drainpipe 17, position
Oil in the top in water sealed tank 18, which can be squeezed, to be entered in External floating roof tank 21.
In step c, according to knowhow, when the water surface in drainpipe 17 is higher than pasta 50cm in drainpipe 17 or so
When, slow decentralization water seal recovery device is until reach the bottom of drainpipe 17.Wherein, slow decentralization water seal recovery device be in order to
Make way for the oil in drainpipe 17 to enter behind the bottom of water sealed tank 18, because its density is less than the density of water, and can fully float
To the top of water sealed tank 18, then moving down and enter in External floating roof tank 21 with water seal recovery device again, therefore, work as water seal
When recovery device reaches the bottom of drainpipe 17, the oil in drainpipe 17 is had enter into External floating roof tank 21.
Because drainpipe 17 is welded by the tubing string of different inner diameters, in order to ensure the water surface in drainpipe 17 always above
Pasta 50mm or so, should continue the water filling into drainpipe 17 during decentralization water seal recovery device.
In step d, rotatable connection bar 1 makes sealing rubber plug 7 move up up to sealing rubber plug 7 leaves clamping rings 4, is
In order to which clamping rings 4, packer ring 5 and water of the sealing rubber plug 7 on the sealing surface that drainpipe 17 is formed are passed through into fixation
The endoporus 401 of annulus and the inside for entering drainpipe 17, and then the oil in drainpipe 17 is replaced as water.In the process,
The water filling into drainpipe 17 should be continued, it is ensured that the water surface in drainpipe 17 is higher than pasta 50mm or so.
After completing the procedure, it should check that the liquid level in drainpipe 17 is pasta or the water surface, if pasta and having
If big gauging, above-mentioned steps a to step e is continued executing with, untill water is all in drainpipe 17.
It can be seen that, the water seal restoration methods of the external floating roof tank emergency drainage device can not only be effectively by emergency drainage device
Interior oil is all replaced as water, recovers water seal resistance；And operation is also allowed for, the plenty of time is saved, storage tank operation is eliminated
The potential safety hazard brought.
