Abstract
A kind of tank car oil inlet port airbag sealing unit, comprise shutoff oil inlet port air sac sealing pad and for executing stressed oil cylinder to air sac sealing pad, the bottom of oil cylinder is rack-mount, and air sac sealing pad is pushed against on oil inlet port by a clamping pad by the piston rod of oil cylinder.Air sac sealing pad is pressed on oil inlet port by using oil cylinder by the utility model, coordinates by very large pressure and air bag the sealing completely realized oil inlet port; Simultaneously, the depressed part that air sac sealing pad is arranged by its top is connected with clamping pad, it can be rotated around clamping pad, by rotating, fitted completely in the tank car surface near air sac sealing pad and oil inlet port, and the inflation gathered in air sac sealing pad bottom is protruding, and this structure is in high pressure situation, bulging deformation is formed and is similar to labyrinth sealed structure, further improves the effect of sealing.
Description
Technical field
The utility model relates to a kind of air sac sealing structure, particularly relates to a kind of oil inlet port to tank car and has carried out hermetic airbag structure.
Background technology
tank car oil inlet port is originally that employing end cap carries out mechanical fixing seal when sealing, and this kind of sealing means does not play good sealing effectiveness, produces oily vapour and leaks, cause environmental pollution and the wasting of resources.
Utility model content
In order to solve the above problems, the utility model overcomes the defect that existing mode of operation exists, and provides a kind of tank car oil inlet port airbag sealing unit, utilizes air bag and hydraulic ram to realize complete positiver sealing to tank car oil inlet port.
For realizing above-mentioned technical purpose, the technical scheme that the utility model adopts is: a kind of tank car oil inlet port airbag sealing unit, comprise a shutoff oil inlet port air sac sealing pad and for executing stressed oil cylinder to air sac sealing pad, the bottom of oil cylinder is rack-mount, and air sac sealing pad is pushed against on oil inlet port by a clamping pad by the piston rod of oil cylinder; One end of transport pipe runs through clamping pad and air bag packing seal is deep in tank car oil tank.
The upper surface of described air sac sealing pad is provided with depressed part, and clamping pad is fastened in this depressed part, and after air sac sealing pad gas, clamping pad clamps by depressed part, to realize the flexible connection of clamping pad and air bag packing seal; The lower surface of described air sac sealing pad and the outer wall adhered shape of tank car oil tank oil inlet port surrounding, and the arc-shaped protrusions heaved after lower surface being densely covered with inflation.
The lower rotation of described support is arranged on tank car, drives oil cylinder and clamping pad to be rotated away from air sac sealing pad to make it.
Described clamping pad is a metal backing plate, and the bottom of backing plate is provided with rubber layer and forms elastic compression to make itself and air sac sealing pad.
Beneficial effect: air sac sealing pad is pressed on oil inlet port by using oil cylinder by the utility model, coordinates by very large pressure and air bag the sealing completely realized oil inlet port; Simultaneously, the depressed part that air sac sealing pad is arranged by its top is connected with clamping pad, it can be rotated around clamping pad, by rotating, fitted completely in the tank car surface near air sac sealing pad and oil inlet port, and the inflation gathered in air sac sealing pad bottom is protruding, and this structure is in high pressure situation, bulging deformation is formed and is similar to labyrinth sealed structure, further improves the effect of sealing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local structure schematic diagram of air sac sealing pad, clamping pad;
In figure: 1, tank car oil tank, 2, support, 3, oil cylinder, 4, transport pipe, 5, clamping pad, 6, air sac sealing pad, 601, depressed part, 602, arc-shaped protrusions.
Detailed description of the invention
For further setting forth the utility model for the technological means reaching predetermined utility model object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to a kind of tank car oil inlet port airbag sealing unit that foundation the utility model proposes, its detailed description of the invention, structure, feature and effect thereof, be described in detail as follows described in literary composition.
Relevant aforementioned and other technology contents, Characteristic of the present utility model, can clearly present in the detailed description of following cooperation with reference to graphic preferred embodiment.By the explanation of detailed description of the invention, when can to the utility model for the technological means reaching predetermined object and take and effect obtain more deeply and concrete understanding, but institute's accompanying drawings is only to provide with reference to the use with explanation, is not used for being limited the utility model.
As shown in the figure, a kind of tank car oil inlet port airbag sealing unit, comprise a shutoff oil inlet port air sac sealing pad 6 and for executing stressed oil cylinder 3 to air sac sealing pad 6, the bottom of oil cylinder 3 is arranged on support 2, and air sac sealing pad 6 is pushed against on oil inlet port by a clamping pad 5 by the piston rod of oil cylinder 3; One end of transport pipe 4 runs through clamping pad 5 and air bag packing seal 6 is deep in tank car oil tank 1.
Above-mentioned is basic embodiment of the present utility model, can do further improvement, optimization and restriction on above basis:
As, the upper surface of described air sac sealing pad 6 is provided with depressed part 601, and clamping pad 5 is fastened in this depressed part 601, and after air sac sealing pad 6 is inflated, clamping pad 5 clamps by depressed part 601, to realize the flexible connection of clamping pad 5 and air bag packing seal 6; The lower surface of described air sac sealing pad 6 and the outer wall adhered shape of tank car oil tank 1 oil inlet port surrounding, and the arc-shaped protrusions 602 heaved after lower surface being densely covered with inflation;
And for example, the lower rotation of described support 2 is arranged on tank car, drives oil cylinder 3 and clamping pad 5 to be rotated away from air sac sealing pad 6 to make it;
For another example, described clamping pad 5 is a metal backing plate, and the bottom of backing plate is provided with rubber layer and forms elastic compression to make itself and air sac sealing pad 6.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art are not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
