Description
Technical field
The utility model relates to a kind of sealing device more particularly to a kind of storage tank inspection hole sealing devices.
Background technique
Inspection hole refers to the preformed hole that safety inspection and inspection are used on pressure vessel, such as manhole, hand hole and screw thread pipe close
Inspection hole etc., manhole and hand hole also have the effects of installation internals, maintenance concurrently, and screw thread pipe close inspection hole is with standard taper pipe thread
Tube socket and equipped closing cock or cap structure.From security consideration, pressure vessel internal diameter > 1000mm should at least open up 1
Manhole；1 manhole of l000mm > internal diameter > 500mm, Ying Kaishe or two hand holes；500mm > internal diameter > 300mm, should open up two
A hand hole needs to seal under inspection hole normal condition, and existing storage tank inspection hole sealing mostly uses bolt type to seal and Gai Shimi
Envelope, the disadvantage is that bolt type sealing is unfavorable for inspection of uncapping, and pot-cover-type is then poorly sealed, and volatile materials causes dirt to environment
Dye.
Summary of the invention
According to the above technical problem, the utility model provides a kind of storage tank inspection hole sealing device, it is characterised in that including
Inner ring, sealed outer ring, sealing room, sealing liquid, boss, the first magnet, sealing ring, sealing cover, the second magnet, handle are sealed,
The sealing inner ring and sealed outer ring constitute sealing room, and the sealing is indoor filled with sealing liquid, the sealing inner ring and sealing
It is respectively equipped with boss at the top of outer ring, the boss where the sealed outer ring is equipped with the first magnet, is equipped on the upside of the sealing room
Sealing cover, the sealing cover downside are equipped with sealing ring, and the sealing ring insertion seals in room, the sealing cover bottom and the first magnetic
The corresponding position of iron is equipped with the second magnet, is equipped with handle at the top of the sealing cover.
The sealing inner ring and sealed outer ring be respectively adopted it is fixed at the top of welding or bonding way and storage tank, therebetween solder joint or
Sticky point seals No leakage.
The sealing ring is fixed by the way of welding or bonding with sealing cover, and solder joint or sticky point seal No leakage therebetween.
The projection width is a quarter for sealing distance between inner ring and sealed outer ring.
The sealing ring is located at sealing inner ring and sealed outer ring middle position.
First magnet is magnetic opposite with the second magnet opposite face.
It is 50mm that liquid height is sealed in the sealing room, and the sealing ring immerses 30mm in sealing liquid.
The sealing liquid is water.
The sealing cover and storage tank keep horizontal.
The sealing ring length is less than the height of sealing room.
The utility model has the following beneficial effects:
1, under normal condition, the sealing ring on sealing cover is immersed in sealing liquid, inspection hole is sealed, at this time the
Not in magnetic attracting distance range, sealing ring bottom is immersed in sealing liquid, needs manually to carry out for one magnet and the second magnet
When maintenance, manhole can be entered by being removed sealing cover by handle, so that inspection hole switch is simple, it is easy to operate.
2, sealing indoor sealing liquid is water, energy conservation and environmental protection, while guaranteeing airtight quality, and volatile materials is avoided to let out
Leakage.
3, when the liquid level decline in sealing room is more, the first magnet attracts each other with the second magnet, declines sealing ring
To extreme lower position, it is ensured that sealing ring bottom be still immersed in sealing liquid in, guarantee sealing validity, with reserve grace time to
Sealing interior re-injects sealing liquid, avoids pollution of the volatile materials leakage to environment.
Detailed description of the invention
Fig. 1 is the utility model main structure chart；
Such as figure, sealing inner ring -1, sealed outer ring -2, sealing room -3, sealing liquid -4, boss -5, the first magnet -6, sealing
Ring -7, sealing cover -8, the second magnet -9, handle -10, storage tank -11, inspection hole -12.
Specific embodiment
Shown in reference to the accompanying drawing, the utility model is further described: the utility model is a kind of inspection of storage tank 11
Look into 12 sealing device of hole, including sealing inner ring 1, sealed outer ring 2, sealing room 3, sealing liquid 4, boss 5, the first magnet 6, close
Seal ring 7, sealing cover 8, the second magnet 9, handle 10 seal inner ring 1 and sealed outer ring 2 and constitute sealing room 3, sealing inner ring 1 with it is close
Envelope outer ring 2 is respectively adopted at the top of welding or bonding way and storage tank 11 and fixes, and solder joint or sticky point seal No leakage therebetween, seals room
Filled with sealing liquid 4 in 3, sealing sealing 4 height of liquid in room 3 is 50mm, and sealing ring 7 immerses 30mm in sealing liquid 4, close
Sealing liquid body 4 is water, seals and is respectively equipped with boss 5 at the top of inner ring and sealed outer ring, and 5 width of boss is sealing inner ring and sealed outer ring
Between distance a quarter, boss 5 where sealed outer ring is equipped with the first magnet 6, seals and be equipped with sealing cover 8 on the upside of room 3,
