Abstract
A cylinder specialized for a pneumatic compression type oil gas recycling sealing device of a train comprises a medium overcurrent pipe and a sealing cover which is matched with a top port opening of a train tanker. A circle of dovetail slot is arranged along the outer edge of the lower surface of the sealing cover. A rubber sealing gasket is arranged at the dovetail slot. The rubber sealing gasket is provided with a relatively hard dovetail connecting part. A relatively soft sealing part is arranged below the dovetail connecting part. The central part of the sealing cover is provided with a medium overcurrent pipe mounting hole. A cylinder body which is sleeved outside the medium overcurrent pipe is arranged below the sealing cover. A pressure chamber is formed between the outer wall of the medium overcurrent pipe and the inner wall of the cylinder body. The pressure chamber is internally provided with a piston. The piston is sleeved on the medium overcurrent pipe and is fixedly connected with the same. The cylinder is particularly designed and manufactured for aiming at the sealing device. Not only can a stable and reliable locking force be provided, but also the cylinder provided by the utility model can be combined with a sealing recycling assembly. The cylinder further has advantages of: realizing compact structure and economical and environment-friendly performance, greatly reducing integral weight of the equipment, and facilitating combination use with a crane tube.

Technical field
The utility model relates to a kind of highly volatile oil product or chemical medium handling equipment, and particularly a kind of train Pneumatic pressure compact form oil gas reclaims sealing arrangement Special cylinder.
Background technology
Cone cap or flat cap that the conventional reliable outer arm of sealing arrangement in the field of oil gas recovery is at present locked, the campstool type sealing arrangement of reliable deadweight or dependence magnetic seal, the thrust deficiency that these Manual sealing devices not only provide, completely sealable tank mouth, and inconvenient operation, labour intensity is large.On the nanubrium of oil filling riser, add cylinder in addition, rely on the outer arm rigidity of oil filling riser to compress tank mouth, though this device can be realized automation, because oil filling riser outer arm is longer, rigidity is inadequate, has sedimentation when tank car charge of oil in addition, so or sealable tank mouth completely.Above-mentioned sealing arrangement thrust deficiency is the major cause that current sealing arrangement can not reach seal request completely, becomes the technical bottleneck of the gas recovery system for oil raising percent recovery.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, and the train Pneumatic pressure compact form oil gas that has proposed a kind of compact conformation reclaims sealing arrangement Special cylinder.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of train Pneumatic pressure compact form oil gas reclaims sealing arrangement Special cylinder, be characterized in: the seal cover cap that comprises medium overcurrent pipeline and coordinate with train tanker vehicle top tank mouth, be provided with a circle dovetail furrow along the lower surface outer of seal cover cap, rubber gasket is equipped with at dovetail furrow place, rubber gasket is provided with the harder dovetail connecting bridge doing coordinating with above-mentioned dovetail furrow, in order to be connected firmly, below dovetail connecting bridge, be provided with the softer hermetic unit doing, can, in when sealing compensating tank mouth flatness error, improve sealing property, seal cover cap center is provided with the mounting hole that medium overcurrent pipeline passes through, the other seal cover cap of mounting hole is provided with oil gas and reclaims mouth, below seal cover cap, be provided with the cylinder barrel being enclosed within outside medium overcurrent pipeline, described oil gas reclaims mouth and is arranged on the seal cover cap outside cylinder barrel, cylinder barrel two ends are provided with upper cover and lower cover, the center of upper cover has hole, just the upper hole place of upper cover is had to lower hole at lower cover, medium overcurrent pipeline runs through He Xia hole, hole, medium overcurrent pipeline and upper, between the hole wall in lower hole, be provided with sealing arrangement, upper cover, lower cover connects as one by bolt and seal cover cap, between the outer wall of medium overcurrent pipeline and the inwall of cylinder barrel, form pressure chamber, in pressure chamber, be provided with piston, piston bush is contained on medium overcurrent pipeline and with medium overcurrent pipeline and is fixedly connected with.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, is provided with upper covering the epicoele free air diffuser communicating with pressure chamber, under cover and be provided with the cavity of resorption free air diffuser communicating with pressure chamber.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and the upper end of medium overcurrent pipeline is provided with butt flange.
The utility model compared with prior art, that pneumatic clamping self-locking type oil gas reclaims important parts in sealing arrangement, be placed in the inside of sealing arrangement, for sealing arrangement rubber seal provides failure-free thrust, by with the automatic control that can realize sealing arrangement being connected of pneumatic valve, this cylinder is not to be independently present in sealing arrangement, but utilize some parts of sealing arrangement as the constituent elements of cylinder, as the large cover of the end cap of cylinder and sealing arrangement combines, the piston rod of cylinder is to utilize the nanubrium of sealing arrangement overcurrent pipeline and oil filling riser to make, can pass through medium as nanubrium, can connect again piston realizes pneumatic, simultaneously also as the adapter shaft of sealing arrangement catch gear.Be for the manufacture of sealing device structure customized design, reliable and stable coupling mechanism force can not only be provided, and can and Recovery of Seal Oil assembly be combined as a whole, compact conformation, economic environmental protection, has alleviated the overall weight of equipment greatly, is more conducive to supporting the use of same oil filling riser.
