Description
Technical field
This utility model is related to fill sealing means of crane-pipe on automobile, and in particular to a kind of gasbag-type sealing means of crane-pipe.
Background technology
Oil truck currently used in the market, its caliber size disunity are generally used for the conventional hermetic cover of closed loading
Cannot realize fully sealing, sealing property is poor, leaking for a large amount of harmful gass occurs during oil loading, it is right to cause
The heavy damage of working site environment, directly harm field personnel's is healthy；As oil product oil gas constantly volatilizees,
So that working environment there is also certain potential safety hazard, meanwhile, substantial amounts of resource is wasted, work efficiency is affected.
Due to the inlet of tank car exist the difference of diameter, out-of-roundness and planar distortion difference, when making
With during, poorly sealed, volatile, oil and gas leakage is commonly there is.Meanwhile, tank car mouth adnexa can be to sealing device
Produce obstruction, it is impossible to ensure to fully seal.
Utility model content
For solving above-mentioned technical problem, this utility model provides a kind of bellows sealing means of crane-pipe, to reach change mesh
Front seal style can not be suitable for the technical barrier of all tank car mouths, be greatly enhanced the purpose of entrucking sealing property.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of bellows sealing means of crane-pipe, including stretching into the flexible nanubrium in tank car mouth, is set with outside the flexible nanubrium
Gas phase pipe, the gas phase pipe outer wall are welded with cover plate, and the cover plate periphery is provided with the three-jaw for stretching out and supports, the gas phase pipe
Outer wall is provided with air bag positioned at the cover plate lower position, and the gas phase pipe outer wall is provided with draw-in groove, and up and down the two of the air bag
End is embedded in the draw-in groove, and is fixed by locking belt, and the air bag is provided with air inlet pipe, and the air inlet pipe passes through the gas phase
Pipe；The flexible nanubrium is welded on the liquid phase adpting flange of swivel joint.
In such scheme, the gas phase Gutron crosses one section of pipeline connection gas phase flange being obliquely installed.
In such scheme, on the gas phase pipe, support tube and stop screw is provided with positioned at air bag lower position.
In further technical scheme, the preventing oil spill probe stretched in tank car mouth is installed on the gas phase pipe.
By above-mentioned technical proposal, bellows sealing device that this utility model is provided using air bag dilatation provide compared with
Wide closure size scope, can adjust orientation by swivel joint, effectively avoid the obstruction of tank car mouth adnexa；Air bag is direct
Gas phase pipe outer wall is installed on, the air bag mounting structure of complexity can be saved, and it is possible to save airbag structure；Three-jaw is supported and is added
Long cover plate, effectively avoids obstruction of the tank car mouth adnexa to sealing device, can be suitable for the tank car mouth more than cover plate external diameter, cover
Almost the size range of existing all truck tank mouths, changes the technology hardly possible that current seal style can not be suitable for all car mouths
Topic, is greatly enhanced entrucking sealing property.
