Preferably, described seal cover cap comprises top cover labyrinth and lower sealing cover, and the size of lower sealing cover is less than top cover labyrinth.
Preferably, described top cover labyrinth and lower sealing cover are circle, and top cover labyrinth overlaps with the center shaft of lower sealing cover.
Preferably, described cylinder is connected with oil filling riser vertical tube by its piston rod, and described position locking device comprises the dead bolt for hooking the inner upper wall of tank car, switch and the support of controlling dead bolt ejection and regaining, and described support is connected with oil filling riser vertical tube.
Preferably, on described seal cover cap, be also provided with the return gas channel for discharging oil gas in train tank car.
Useful technique effect of the present utility model is:
(1) the utility model provides a kind of upper dress oil filling riser locking type sealing arrangement that can be used for train closed loading, and good sealing effect is better than the common seal type on the market such as cone seal, the sealing of flat cover shape, the sealing of capsule formula.
(2) the utility model applicable surface is wider, can meet most vehicles on the market, and seal cover cap comprise two-layer up and down, can be applicable to simultaneously size two kinds of tank car mouths vehicle.
(3) the utility model is easy and simple to handle, and durable can greatly reduce sealing cost.
Brief description of the drawings
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
Fig. 1 is structure diagram of the present utility model.
In figure: 1-top cover labyrinth, 2-lower sealing cover, 3-rubber pad, 4-return gas channel, 5-position locking device, 6-pipe link, 7-oil filling riser vertical tube, 8-cylinder.
Detailed description of the invention
By reference to the accompanying drawings, a kind of locking type sealing arrangement for train closed loading, comprise the seal cover cap for sealing train tank car mouth, described seal cover cap comprises top cover labyrinth 1 and lower sealing cover 2, top cover labyrinth 1 is circle with lower sealing cover 2, the center shaft of the two overlaps, and the size of lower sealing cover 2 is less than top cover labyrinth 1, can be applicable to the vehicle of two kinds of tank car mouths of size simultaneously.Be provided with the border, bottom of lower sealing cover 2 rubber pad 3 aliging with train tank car mouth edge at top cover labyrinth 1.On top cover labyrinth 1, be also provided with the return gas channel 4 for discharging oil gas in train tank car.Below seal cover cap, be provided with for hooking the inner upper wall of tank car so that seal cover cap compresses the position locking device 5 of train tank car mouth, seal cover cap is connected with position locking device 5 by pipe link 6, described position locking device 5 comprises the dead bolt for hooking the inner upper wall of tank car, switch and the support of controlling dead bolt ejection and regaining, and described support is connected with oil filling riser vertical tube 7.Offer the circular hole that can pass for oil filling riser vertical tube 7 at the center of seal cover cap, be provided with the cylinder 8 that drives oil filling riser vertical tube to move above seal cover cap, cylinder 8 is connected with oil filling riser vertical tube 7 by its piston rod.
The using method of above-mentioned locking type sealing arrangement, specifically comprises the following steps:
The first step, before pair oil work starts, gos deep into tank car inside by oil filling riser vertical tube, and seal cover cap is covered to tank car mouth.Cylinder traction oil filling riser vertical tube moves, and makes to move on oil filling riser vertical tube, and the dead bolt that ejects position locking device hooks the upper wall of train tank car inside (edge under tank car mouth), by reinforcing, realizes lock sealing.
Second step, is paying after oily end-of-job, and the nanubrium of external force traction oil filling riser moves, and oil filling riser vertical tube is moved down, and the dead bolt that position locking device ejects unclamps withdrawal, takes out standpipe, and oil filling riser resets.
In this device, seal cover cap, with rubber pad, forms sealing surface along the limit alignment of train tank car mouth, fully contacts with the tank car mouth place of tank car; Position locking device 5 is for hook the inner upper wall of tank car in train loading process, thereby makes described sealing arrangement can realize tight connection with described tank car; External force is provided by cylinder 8 grades.Cylinder 8 needs Petrochemical Enterprises that source of the gas is provided, and for adjusting nanubrium position, provides seal cover cap and train tank car the tight-lipped close needed external force that is connected.Wherein sealing cover strip is divided into two-layer being top cover labyrinth 1 and lower sealing cover 2, can being applicable to the vehicle of two kinds of tank car mouths of size simultaneously.
The nanubrium of external force traction oil filling riser moves, and in the time that nanubrium declines, position locking device is regained; In the time that nanubrium rises, position locking device ejects and opens.Before pair oil work starts, oil filling riser vertical tube is goed deep into tank car inside, seal cover cap is covered to tank car mouth.The nanubrium of external force traction oil filling riser moves, and makes to move on oil filling riser vertical tube, ejects the upper wall (edge under tank car mouth) that position locking device hooks slot train inside, by reinforcing, realizes lock sealing.Paying after oily end-of-job, the nanubrium of external force traction oil filling riser moves, and oil filling riser vertical tube is moved down, and the position locking device of ejection unclamps withdrawal, takes out standpipe, and oil filling riser resets.
The part of not addressing in aforesaid way is taked or is used for reference prior art and can realize.
It should be noted that, under the instruction of this specification sheets, any equivalents that those skilled in the art have done, or obvious variant, all should be within protection domain of the present utility model.
