Description
Technical field
The invention belongs to oil filling riser technical field, more specifically to dress oil filling riser bellows sealing device in one kind.
Background technology
Oil filling riser, is a kind of pipe of Telescopic movable as its name suggests, is usually used in the handling of oil, chemical industry harbour liquid, can
To say that it is the special equipment during petrochemical industry fluid assembly and disassembly.At present, common oil filling riser can be divided into dress formula oil filling riser with
Dress formula oil filling riser, and most of oil trucks use upper dress formula oil filling riser when loading and unloading oil product.But designed due to being produced to oil truck
Lack Specification, cause the tank mouth size of existing oil truck different, in actual use exist because poorly sealed close and
The shortcomings of causing volatile oil product, oil gas leakage, and then carry out very big difficulty to petroleum vapor recovery collection belt, so as to directly affect oil
The utilization ratio of gas recovery system, and also there is the problems such as pollution environment, waste of energy.
In the prior art, the methods of adding bellows to seal for upper dress formula oil filling riser sealing generally use cone seal, magnetic force, but
These methods there are it is certain the defects of, can there are gas leak phenomenon such as when adding bellows to seal using cone seal or magnetic force；
And bellows of the prior art sealing is complicated, cumbersome, and its air bag is under long-term work environment, because it is upper
Often rub during lower handling with groove tank car tank mouth, therefore, abrasion can be produced or even galled, if handling are poisonous
During volatile liquid, easily cause to produce staff certain danger；These cannot all solve the tank because of oil truck
The mouth different and existing poorly sealed close problem of size.Similarly, Chinese patent 200520005917.7 discloses one kind and can rise
Sealing cap of oil filling riser drops, it is linked in sequence by flexible jar support, telescoping cylinder and seal cap and formed, and sealing can be made by being connected with seal cap
The telescoping cylinder of cap oscilaltion, although the program can solve the problems, such as that the tank mouth size of oil truck is different to a certain degree,
Since seal cap is pressed on the tank mouth of oil truck by no external force, actual sealing effect is also bad.
The content of the invention
1st, to solve the problems, such as
For the above-mentioned problems in the prior art, the present invention, which provides, fills oil filling riser bellows sealing device, its energy in one kind
Solve the problems, such as because the tank mouth size of oil truck is different and existing for it is poorly sealed close, and by pressure difference by the air bag of sealing cover
The tank mouth of oil truck is pressed on, and it can avoid air bag from rubbing with groove tank car tank mouth during upper and lower handling, therefore
Abrasion or even the generation of the phenomenon galled can be produced by avoiding.
2nd, technical solution
To solve the above-mentioned problems, the technical solution adopted in the present invention is as follows：
Fill oil filling riser bellows sealing device in one kind, including flexible nanubrium, gas phase pipe, cover board, inverted round stage and air bag stretch dress
Put, the cover board is cylinder, and the inverted round stage is fixed on the lower end of the cover board and is coaxial therewith setting, the flexible nanubrium
Through the cover board and inverted round stage circle centre position, an annular groove is provided with the center of the cover board vertically, the air bag is stretched
Compression apparatus includes casing, air bag, air-pressure chamber, gas phase air inlet pipe and push plate, is fixedly connected with the middle part of the annular groove in circular ring shape
And push plate made of rubber, and it forms an air-pressure chamber with the annular groove inner cavity, the push plate is backwards to the cover board
Circle centre position is outwards connected with circular ring shape air bag by being adhesively fixed, and the air bag is closed structure simultaneously gassy, described to push away
Plate face is fixedly connected with multiple casings to the inside level of circle centre position of the cover board, and described sleeve pipe includes loop bar, sleeve and spring,
The loop bar is socketed in the sleeve, and is fixedly connected with the push plate, and the sleeve is consolidated with the annular groove intracavity bottom
Fixed connection, the spring pocket on the loop bar and sleeve, its both ends respectively with the push plate and the annular groove intracavity bottom
It is fixedly connected, the air-pressure chamber is communicated with gas phase air inlet pipe, the cover board between the flexible nanubrium and the air-pressure chamber
With gas phase pipe has also been passed vertically through on inverted round stage.
Preferably, the multiple casing lines up circle using the center of circle of the cover board as the center of circle and that waits angle be located at the air pressure
It is indoor.
Preferably, the opening of the annular groove seamlessly transits.
3rd, beneficial effect
Compared with the prior art, beneficial effects of the present invention are：
(1) present invention solve the problems, such as because the tank mouth size of oil truck is different and existing for it is poorly sealed close, and pass through pressure
The strong poor tank mouth that the air bag of sealing cover is pressed on to oil truck, actual sealing effect are preferable；
(2) structure of bellows of the invention sealing is simple, easy to operate, and it can avoid gas during upper and lower handling
Capsule rubs with groove tank car tank mouth, therefore avoids under long-term work environment, can produce the phenomenon of abrasion or even worn-off
Occur, and when loading and unloading the liquid of toxic and volatile, greatly reduce the danger produced to staff；
(3) present invention also has the advantages that simple in structure, design is reasonable, easily fabricated.
