Description
Technical field
The utility model belongs to liquid loading and unloading technical field, and in particular to a kind of petroleum vapor recovery Follow-up type seal cap.
Background technique
Oil filling riser currently used for closed loading largely use seal closure and nanubrium fixed form during entrucking by
In the increasing of load-carrying, tank car can decline 3-6cm distance, and conventional hermetic cover can not compensate this portion void, and present oil gas is caused to store up
It runs in industry cargo handling process, oil gas volatilization amount is larger, wastes vast resources, is unfavorable for the popularization of long-term sustainable development and answers
With, prior art gas recovery system for oil, but load and unload source and not can solve closed problem always, lead to petroleum vapor recovery
The effect is unsatisfactory, and in order to better solve petroleum vapor recovery effect, this band petroleum vapor recovery Follow-up type seal closure can be fine
Solve the problems, such as encountered in storage and transportation industry it is this, make oil gas reduce volatilization even it is non-volatile.
Summary of the invention
The purpose of this utility model is to provide a kind of petroleum vapor recovery Follow-up type seal caps, return to better solve oil gas
It produces effects fruit, realizes that oil gas reduces volatilization even nonvolatile purpose.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
A kind of petroleum vapor recovery Follow-up type seal cap, which is characterized in that compressed spring compensation device is arranged in seal cap top, leads to
Overcompression spring compensator come realize confined space compensate, seal cap side be equipped with petroleum vapor recovery mouth, the other side be equipped with liquid level
Device connecting cover plate.
Further, the compressed spring compensation device structure is as follows:
Guide rod and compressed spring are equipped between mounting flange and seal cap, the compressed spring is placed between guide rod.
Further, seal cap be equipped with cover board, between cover board and guide rod by screw rod connect, the mounting flange and
It is connected between guide rod by screw rod.
Further, seal cap uses pyramidal structure.
Further, level gauge connecting cover plate is connect by bolt with cover board.
Further, seal cap is equipped with sealant.
The utility model has the following beneficial effects:
Band petroleum vapor recovery Follow-up type seal cap uses cone seal cap structure, and on the top of seal cap, setting is specially designed
Compressed spring compensation device realizes that confined space is compensated by compressed spring compensation device, i.e., each entrucking holddown spring is mended
Device is repaid, by closed loading since load-carrying increases, tank car height is reduced, and at this moment seal cap makes to seal by spring compensator
Cap follows tank car mouth to move down to continue to compress seal cap is made to continue to be bonded with tank car mouth, realizes and freely follows up sealing, realizes closed dress
The fixing pipe structure of special return-air is arranged in seal cap for vehicle, realizes petroleum vapor recovery and environmental protection.
The utility model structure is simple, and production cost is low, is suitble to seal use on nanubrium.
Detailed description of the invention
Fig. 1 is Follow-up type seal cap structure chart.
1, mounting flange, 2, guide rod, 3, compressed spring, 4, level gauge connecting cover plate, 5, seal cap, 6, petroleum vapor recovery
Mouthful, 7, cover board, 8, sealant.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, a kind of petroleum vapor recovery Follow-up type seal cap, which is characterized in that compressed spring is arranged in 5 top of seal cap
Compensation device realizes that confined space is compensated by compressed spring compensation device, and 5 side of seal cap is equipped with petroleum vapor recovery mouth 6, separately
Side is equipped with level gauge connecting cover plate 4.
The compressed spring compensation device structure is as follows: guide rod 2 and compression are equipped between mounting flange 1 and seal cap 5
Spring 3, the compressed spring 3 are placed between guide rod 2.Seal cap 5 is equipped with cover board 7, passes through between cover board 7 and guide rod 2
Screw rod connection, is connected between the mounting flange 1 and guide rod 2 by screw rod.
Seal cap 5 uses pyramidal structure；Level gauge connecting cover plate 4 is connect by bolt with cover board 7.Seal cap 5 is equipped with
Sealant 8.
Embodiment:
Band petroleum vapor recovery Follow-up type seal cap uses cone seal cap structure, and on the top of seal cap, setting is specially designed
Compressed spring compensation device realizes that confined space is compensated by compressed spring compensation device, i.e., each entrucking holddown spring is mended
Device is repaid, by closed loading since load-carrying increases, tank car height is reduced, and at this moment seal cap makes to seal by spring compensator
Cap follows tank car mouth to move down to continue to compress seal cap is made to continue to be bonded with tank car mouth, realizes and freely follows up sealing, realizes closed dress
The fixing pipe structure of special return-air is arranged in seal cap for vehicle, realizes petroleum vapor recovery and environmental protection.
Detailed process is as follows:
Petroleum vapor recovery Follow-up type seal cap is mounted on nanubrium, nanubrium is passed through in the notch of tank car, with tank car load-carrying
It increasing, tank car height reduces, and can decline 3-6cm distance, and conventional hermetic cover can not compensate this portion void, when there is gap,
The utility model compressed spring 3 discharges elastic pressure, can squeeze seal cap 5 to tank car direction, and then compensate this portion void,
It plays sealing of freely following up and realizes petroleum vapor recovery and environmental protection.
Above description is only a specific implementation of the present invention, but the protection scope of utility model is not limited to
This, anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can readily occur in or is replaced
It changes, should all cover within the protection scope of utility model.
