Description
Technical field
The utility model is related to a kind of sealing device, particularly a kind of folding sealing cap.
Background technology
At present, automobile dress oil filling riser closed major part in the market is using cone seal hat shape formula, but oil tank in the market
Vehicle caliber size disunity, while some tank cars are opened after covering, lid is just interfered with seal cap, and cone seal cap at all can not
It puts tank mouth into, while can decline 3 ~ 6 cm distances since load-carrying increases automobile during entrucking, conventional hermetic cap can not be mended
This portion void to be repaid, is caused in present Oil ＆ Gas Storage industry cargo handling process, oil gas volatilization amount is larger, though there is gas recovery system for oil,
But handling source not can solve closed problem always, so the effect of petroleum vapor recovery and ideal.
Invention content
The technical problems to be solved in the utility model is in view of the deficiencies of the prior art, to propose a kind of suitable for all oil tanks
Vehicle bore can avoid oil gas volatilization, the folding sealing cap for improving petroleum vapor recovery efficiency.
The technical problems to be solved in the utility model is achieved through the following technical solutions.The utility model is a kind of folding
Stacked seal cap, its main feature is that：Including sealed joint pipe, sealed joint pipe includes the sealing with oil truck tank mouth fitted seal
Cap is equipped with terminal pad in the top of seal cap, hollow connection tube is equipped between terminal pad and seal cap, and seal cap passes through lower company
Acting flange connects with hollow connection tube, and the lower connecting flange is fixed on the bottom of hollow connection tube, at the center of seal cap
Pass through hole equipped with the seal cap with the filling oil product of hollow connection tube cooperation；It is equipped in the top of sealed joint pipe and consolidates with oil filling riser vertical tube
Surely the seal cover board to connect is equipped with entrucking folding-compensation mechanism, entrucking folding-compensation between seal cover board and sealed joint pipe
Mechanism includes be located between tank mouth terminal pad outer and seal cover board one circle collapsible rubber, in collapsible rubber
Portion is respectively equipped with the outer tube being fixedly connected with seal cover board and the interior guide rod coordinated with outer tube, and interior guide rod connects with tank mouth
It connects disk to be fixedly connected, the resetting spring being sleeved on interior guide rod is equipped between interior guide rod and outer tube.
In a kind of folding sealing cap technical solution of the utility model, further preferred technical solution is characterized in：
1st, the seal cap is sealing rubber pad；
2nd, in the limiting steel wire rope that outer tube and interior guide rod is avoided to misplace of being internally provided with of collapsible rubber, limit
One end of position steel wire rope is fixedly connected with seal cover board, and the other end and tank mouth terminal pad for limiting steel wire rope are fixedly connected；
3rd, it is equipped with return-air connector at the top of seal cover board；
4th, at the center of seal cover board be equipped with entrucking when nanubrium by connector, sealing plate is installed at connector.
Compared with prior art, the utility model is bonded sealing cap portion, then press with tank mouth first in use
It closes collapsible rubber part height and oil filling riser outer arm is locked, as the loading of freight waggon increases vehicle, pressed by folding
Contracting rubber part to compensate gap caused by vehicle sinking during entrucking, realizes the complete closed loading of tank mouth；Utilize sealing
The elongate structure of the hollow connection tube of connecting tube avoids the interference situation occurred after tank car is uncapped, realizes without hindrance closed.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Referring to the drawings, the specific technical solution of the utility model is further described, in order to those skilled in the art
Member is further understood that the utility model, without forming the limitation to its right.
Embodiment 1, with reference to Fig. 1, a kind of folding sealing cap, including sealed joint pipe, sealed joint pipe includes and oil tank
The seal cap 8 of vehicle tank mouth fitted seal is equipped with terminal pad 5 in the top of seal cap 8, is equipped between terminal pad 5 and seal cap 8
Hollow connection tube 6, seal cap 8 are connected by lower connecting flange 7 with hollow connection tube 6, and the lower connecting flange is fixed on hollow
The bottom of connecting tube is equipped at the center of seal cap and the seal cap of filling oil product is coordinated to pass through hole with hollow connection tube；Close
The top of envelope connecting tube is equipped with the seal cover board 1 being fixedly connected with oil filling riser vertical tube, is set between seal cover board 1 and sealed joint pipe
There is entrucking folding-compensation mechanism, entrucking folding-compensation mechanism includes the circle being located between tank mouth terminal pad outer and seal cover board
