Working principle:
referring to fig. 2-7, the tank opening inclined sealing device of the adaptive tank wagon consists of a ball joint 1, a telescopic cylinder 5, an air duct 3, a sealing gasket 6, a claw 13, a guide cylinder 4 and a protective cover 2, and as shown in fig. 6 and fig. 1, the purpose is that the circumference of the tank opening 14 is tightly attached to the sealing gasket 6, so that no volatile gas overflows into the atmosphere during loading between the tank opening 14 and the sealing gasket 6, and all the volatile gas is discharged to a special oil gas recovery pipeline through the air duct 3.
The specific implementation mode of sealing at the tank opening 14 is as follows:
firstly, the vertical pipe 8 and the guide cylinder 4 are directly inserted into the tank opening 14, because the sealing device adopts the independent telescopic cylinder 5 to drive the claw ring 7, when the claw units 13 corresponding to the supporting spring 10 structure firstly contact the tank wall 15 of the tank wagon, the supporting spring 10 is firstly compressed, meanwhile, the supporting springs 10 beside the rest claw units 13 which are not contacted with the tank wall 15 of the tank wagon are not compressed, the ring plate 11 is inclined until all the claw units 13 on the claw ring 7 are contacted with the tank wall 15 and have a certain elastic force, the state of the claw ring 7 is stable, at the moment, the sealing gasket 6 is tightly attached to the edge of the tank opening 14, and meanwhile, the problem that whether the vertical pipe 8 and the tank opening 14 are coaxial or not is not considered.
The claw ring 7 is controlled by a plurality of independent telescopic cylinders 5, so that the claw ring 7 can move up and down freely along the vertical pipe 8, and when the claw rings 7 are not resisted in the moving process, the claw ring 7 can not deflect in an up-down translation manner; when one or more jaw units 13 of the jaw ring 7 are subjected to resistance, the jaw ring 7 is regulated by compression of the supporting spring 10 at the bottom of the jaw ring, and the jaw units 13 which are not subjected to resistance are not compressed under the action of the elastic force of the supporting spring 10, so that when the sealing device is not concentric with the tank opening 14, the problem that the jaw units of the jaw ring 7 are not in close contact with the inside of the tank opening 14 at the same time is caused.
If the ground where the tank car is parked is a sloping ground, the plane where the edge of the tank opening 14 is located is inclined, and the sealing device can rotate in space by the ball joint 1, so that the plane of the sealing gasket 6 is parallel to the plane where the edge of the tank opening 14 is located, the sealing gasket 6 can be tightly attached to the edge of the tank opening 14, otherwise, risk is always generated between the edge of the tank opening 14 and the sealing gasket 6, and the sealing device is not beneficial to closed loading.
The connecting surface of the ball joint 1 at the upper end of the vertical pipe 8 can have a certain rotation angle, so that the sealing gasket 6 can be well attached to the tank opening 14 of the tank wagon by the multi-degree-of-freedom claw ring 7.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
