Description
Technical field
When the utility model relates to a kind of tank car handling fluid, be centralized recovery volatility oil gas, prevent oil gas to leak the charging arm seal closure device of air, especially a kind of charging arm seal closure of scalable and skew, belongs to fluid conveying field of sealing technology.
Background technology
Shanghai Baosteel Chemical Co., Ltd's Golconda ancillary firm product preparation device and groove tank field adopt charging arm to load and unload fluid to tank car, use the volatility oil gas during handling of effuser centralized recovery simultaneously.Leak for preventing oil gas, charging arm nanubrium is fixedly equipped with seal closure, by cylinder action charging arm nanubrium, seal closure is pressed on tank car tank mouth, to realizing sealing handling (as shown in Figure 1), seal closure 12 with effuser 14 is socketed on charging arm 11, but due to existing charging arm seal closure structure existing defects, when causing tank car to load and unload, volatility oil gas is from the loss of tank mouth, causes have a strong impact on work site environments.The charging arm seal closure structure of current employing is on nanubrium, fix welding cone seal cover, its major defect existed is: when (1) charging arm 11 nanubrium does not insert tank from tank car tank mouth 13 central authorities, because cone seal cover 12 and charging arm nanubrium are fixed, seal closure center offsets with charging arm nanubrium, lid is tank car tank mouth incessantly, cannot realize Jar opening sealer.(2) often there is bite in charging arm swivel joint, rotate the dumb charging arm nanubrium that causes and tilt to insert tank car tank mouth, taper charging arm seal closure working sections becomes oval by circle, therefore cannot coincide with the round section of tank car tank mouth, the effect of seal closure out of reach sealing tank car tank mouth.When above shortcoming all will cause charging arm to inject fluid to tank car, occur that volatility oil gas cannot centralized recovery, from the phenomenon that tank mouth leaks, not only contaminated environment, and harm employee is healthy.
Utility model content
For the deficiencies in the prior art, the utility model improves charging arm seal closure structure, provide a kind of can stretch up and down and horizontal 360-degree skew charging arm seal closure, improve tank car handling fluid time sealing effectiveness, reduce volatility oil gas to leak, improve site work environment.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of charging arm with sealing arrangement that is scalable and that offset, comprise charging arm nanubrium and be nested in the seal closure on described charging arm nanubrium, wherein, described seal closure is provided with liner, flexible link and adjustment handle is provided with outside described liner, described flexible link is socketed in outside charging arm nanubrium, described adjustment handle is arranged at flexible link periphery, flexible link top is provided with stay bearing plate, be connected with load-bearing chain between described stay bearing plate and liner, be provided with inside liner and between charging arm nanubrium and strain at chain.
Preferably, described seal closure is bowl-type.
Preferably, the outer wall of described seal closure is provided with sealing shroud.
Preferably, the connection of the liner of described flexible link and stay bearing plate and seal closure is by Flange joint.
Preferably, the two ends of described load-bearing chain are fixed in stay bearing plate and seal closure by ringbolt and are lining with.
Preferably, described flexible link is oil resistant canvas filler rubber flexible link.
The utility model compared with prior art, there is following significant advantage and effect: charging arm nanubrium is provided with the seal closure that flexible and horizontal 360-degree up and down offsets, sealing effectiveness during raising tank car handling fluid, reduces volatility oil gas and leaks, improve site work environment.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is further elaborated.
As shown in Figure 2, a kind of charging arm with sealing arrangement that is scalable and that offset, comprise charging arm nanubrium 26 and be socketed in the bowl-type seal closure 25 of described charging arm nanubrium 26, bowl-type seal closure 25 outer wall is provided with the sealing shroud 28 of quality of rubber materials, described seal closure 25 top is provided with liner 29, oil resistant canvas filler rubber flexible link 211 and adjustment handle 24 is provided with outside described liner 29, described flexible link 211 is socketed in outside charging arm nanubrium 26 equally, it is peripheral that described adjustment handle 24 is arranged at flexible link 211, flexible link 211 top is provided with stay bearing plate 21, load-bearing chain 23 is connected with between described stay bearing plate 21 and liner 29, the two ends of load-bearing chain 23 are fixed on the liner 29 of stay bearing plate 21 and seal closure by ringbolt 22, described flexible link 211 is connected by upper flange plate 212 with between stay bearing plate 21, being connected by lower flange 210 of the liner 29 of flexible link 211 and seal closure 25, be provided with inside liner 29 and between charging arm nanubrium 26 and strain at chain 27, liner 29 is also provided with effuser 213.
Principle of work of the present utility model is: before charging arm nanubrium inserts tank car tank mouth, load-bearing chain is in stressed tensioned state, for carrying the weight of charging arm seal closure, preventing from being flexible coupling and being drawn inefficacy, and guarantee that seal closure safety is not fallen, strain at chain simultaneously and be in relaxed state.Charging arm nanubrium moves down by cylinder application force and inserts tank car mouth, and when seal closure and tank car tank mouth come in contact, seal closure weight is carried by tank car tank mouthpiece gradually, and load-bearing chain changes relaxed state into by tensioned state, strains at chain and is still in relaxed state.At this moment, no matter whether charging arm nanubrium inserts tank or charging arm nanubrium inclination insertion from tank car tank mouth central authorities, be flexible coupling owing to adopting between seal closure and charging arm nanubrium, seal closure can because of the effect of contact force and gravity to the direction skew do not come in contact automatic capturing fall into tank car tank mouth.Charging arm nanubrium continues to move down, and strains at chain and changes tensioned state into gradually by relaxed state, strains at the drop-down seal closure of chain, and charging arm seal closure is pressed on tank car tank mouth.When straining at chain to the application force of charging arm nanubrium and cylinder action force balance, charging arm nanubrium stops moving down, thus realizes tank car sealing handling.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
