Technical field
The present invention relates to a kind of highly volatile oil product or chemical medium handling equipment, particularly a kind of train Pneumatic pressure compact form oil gas reclaims sealing arrangement Special cylinder.
Background technology
Cone cap or the flat cap of the reliable outer arm locking of sealing arrangement that the field of oil gas recovery is at present conventional, the campstool type sealing arrangement of reliable deadweight or dependence magnetic seal, the thrust that these Manual sealing devices not only provide is not enough, 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 during 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 that gas recovery system for oil improves the percent recovery.
Summary of the invention
The technical problem to be solved in the present invention 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 problem to be solved in the present invention 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: comprise medium overcurrent pipeline and the seal cover cap coordinating with train tanker vehicle top tank mouth, lower surface outer along seal cover cap is provided with a circle dovetail furrow, rubber gasket is equipped with at dovetail furrow place, rubber gasket is provided with the harder dovetail connecting bridge of doing coordinating with above-mentioned dovetail furrow, in order to be connected firmly, below dovetail connecting bridge, be provided with the softer hermetic unit of 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, at lower cover, over against the upper hole of upper cover, locate to have lower hole, 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 problem to be solved in the present invention can also be come further to realize by the following technical programs, upper covering, is provided with 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 problem to be solved in the present invention 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 present invention 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 the automatic control with realizing 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.
