Description
Technical field
It the utility model is related to a kind of cover plate barrel of oil truck tank mouth locking type petroleum vapor recovery sealing device.
Background technology
The cone cap or flat cap of the reliable outer arm locking of the conventional sealing device in petroleum vapor recovery field at present, reliable deadweight or
By the campstool type sealing device of magnetic seal, the thrust deficiency that these Manual sealing devices not only provide, it is impossible to completely close
Sealed cans mouth, and it is inconvenient for operation, and labor intensity is big.The aerating cylinder also on the nanubrium of oil filling riser, by the outer arm rigidity of oil filling riser
Tank mouth is compressed, though the device can realize automation, because oil filling riser outer arm is longer, rigidity is inadequate, and there have in addition during tank car charge of oil to be heavy
Drop, so tank mouth still can not be fully sealed.Above-mentioned sealing device thrust deficiency is that current sealing device can not be fully achieved
The main reason for seal request, turn into the technical bottleneck that device for recovering oil and gas improves the rate of recovery.
Utility model content
The technical problems to be solved in the utility model is the defects of overcoming prior art, there is provided one kind is applied to different tank mouths
Size, the blind flange cylinder of the tank mouth locking type petroleum vapor recovery sealing device of sealed reliable.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
The utility model provides a kind of cover plate barrel of oil truck tank mouth locking type petroleum vapor recovery sealing device, it include with
The closure that tank mouth coordinates at the top of oil truck, pass through hole, the top of the closure provided with nanubrium at the center of the closure
Provided with upper shell, the lower edge of the upper shell connects with the upper surface of the closure；The upper shell is provided with upper lid, described
Upper lid is provided with passes through the just corresponding through hole in hole with the nanubrium on the closure；Oil gas is provided with the side wall of the upper shell
Recovery tube, lower shell is provided with the lower section of the closure, along lower shell outer wall and closure outer on the closure
It is respectively provided with a circle dovetail groove.
Further, it is mounted on rubber gasket at the dovetail groove.
Further, the rubber gasket is provided with the dovetail connection point coordinated with the dovetail groove, connects in dovetail
Connect beneath portions and be provided with hermetic unit, the hardness of the dovetail connection point is more than the hardness of the hermetic unit.
The beneficial effect that the utility model is reached is：
The utility model is applied to different tank mouth sizes using relatively thin high elastic rubber sealing gasket sealing tank mouth, adopts
It is arranged on oat tail groove structure on the lower cover of sealing device, installation separate room is convenient, the soft or hard combination of rubber seal, can seal
When compensate tank mouth flatness error, improve sealing property, it is ensured that tank mouth also can be reliably sealed in the case of tank mouth injustice.Rubber
Glue sealing gasket selects the rubber of unlike material according to the requirement of handling different medium, improves the service life of seal, rubber cushion with
Cover plate is connected using oat tail groove structure, and the connected mode, which avoids, traditional to be embedded steel skeleton with gluing easy to fall off or rubber cushion and make glue
The defects of blocked up cost is too high is padded, and the coupling part of rubber blanket and cover plate is harder, it is ensured that firmly install, hermetic unit is softer,
Ensure sealed reliable.
