Abstract
The utility model relates to a crane tube-used hemispherical sealing plug for oil gas recovery. The hemispherical sealing plug is characterized in that a fixed flat top hemispherical metal liner is arranged at the periphery of the lower end of an oil gas collecting pipe, and a hemispherical rubber outer cover matched with the liner is tightly arranged on the outer part of the metal liner. When applying the sealing plug, the oiling crane tube is inserted into the oil tank opening, and then the hemispherical sealing plug fixed at the lower end of the crane tub can seal the tank opening quickly, despite whether the centre line of the crane tube is skew. Any working section of the hemispherical sealing plug is round, therefore, the hemispherical sealing plug and the round mouth of the tank opening can be matched and sealed under any kinds of status; in the oiling process, the oil gas avoids leaking out but enters into the oil gas collecting pipe.
Description
Technical field
The utility model relates to truck tanker when loading and unloading effumability fluid, for collecting volatile gas at the oil filling riser of oil tank jar mouth installation and the sealing arrangement between jar mouth, especially a kind of oil filling riser semisphere sealing plug that is used for the oil gas recovery.
Background technology
To truck tanker loading and unloading effumability fluid the time, often need manage to seal so that reclaim oil gas at present at oil tank jar mouth.After oil filling riser inserts jar mouth, just with taper oil filling riser rubber stopper seal jar mouth.Existing taper oil filling riser rubber plug existing problems are:
1, when the line of centers of taper oil filling riser rubber plug and oil tank jar mouth disk out of plumb, the oval working sections line that has just become taper oil filling riser rubber plug with jar mouthful a round section line intersect, so can not coincide the effect of out of reach sealable tank mouth.
2, existing rubber plug can not be changed because be fixed on the oil filling riser, so, because oil gas produces to corrode to rubber and influenced the sealing effectiveness of rubber plug, and shortened the service life of sealing plug.
Summary of the invention
Technical problem to be solved in the utility model: be that a kind of good sealing effect will be provided, the oil filling riser semisphere sealing plug that is used for the oil gas recovery of long service life.
As follows for solving the technical scheme that above technical matters adopts: feature of the present utility model is to be provided with fixing flat-top semisphere metal inner lining in periphery, oil gas collection pipe lower end, the outside of being close to metal inner lining is provided with the semisphere rubber sleeve that matches with liner, and the direction seam inwardly that is provided with suitable for reading of rubber sleeve.
Because adopt above technical scheme, the effect of generation is conspicuous:
1, because any working sections of semisphere sealing plug all is round, so no matter whether the oil filling riser line of centers is vertical with the disk of oil tank jar mouth, both sides are can both be with circumference identical and dock, and reached the effect of sealable tank mouth.
2, the semisphere rubber sleeve is looked the corrosion situation and can often be changed, with the sealing of guaranteeing oil tank jar mouth and the recovery of oil gas.
Description of drawings
Fig. 1 is a sectional structure chart of the present utility model.
Among the figure: 1, oil filling riser 2, oil gas collection pipe 3, metal inner lining 4, rubber sleeve 5, oil tank jar mouth
The specific embodiment
With reference to Fig. 1, the utility model is a kind of oil filling riser semisphere sealing plug that oil gas reclaims that is used for, feature is to be provided with fixing flat-top semisphere metal inner lining 3 in periphery, oil gas collection pipe lower end, the outside of being close to metal inner lining is provided with the semisphere rubber sleeve 4 that matches with liner, and the direction seam inwardly that is provided with suitable for reading of rubber sleeve.
When using the utility model, as long as oiling oil filling riser 1 is inserted in the oil tank jar mouth 5, the semisphere sealing plug that then is fixed on the oil filling riser lower end can be sealed the jar mouth soon, no matter whether the oil filling riser line of centers is crooked, because any working sections of semisphere sealing plug all is a circle, so it can both coincide under free position with jar round mouth of mouth and seal, and makes that in the oiling process oil gas can not leak and can only enter the oil gas collection pipe.
