Technical field
The utility model relates to a kind of air sac sealing device, specifically, and the air sac sealing device of oil inlet when being the tank car charge of oil.
Background technology
The oil inlet size specification disunity of present general tank car in use, oil inlet is other to be provided with also that escape vents, safety cut down, fixing other the just different annexes such as ear of lid, tank car is difficult to realize effectively sealing when charge of oil, during therefore each charge of oil, tank car oil inlet a large amount of unpleasant oil gas of all can emerging, contaminated environment.
Summary of the invention
The utility model provides a kind of air sac sealing device, and it will seal the position and change into the oil inlet inboard, has avoided outer various other annexes of tank car oil inlet, and good seal performance can prevent effectively that oil gas from leaking, and reduces the pollution to surrounding environment and air.
For reaching above-mentioned purpose, the utility model provides a kind of air sac sealing device, and it comprises air bag and center frame;
Described center frame is installed in the lower end of tank car metal arm charge of oil pipe, and the method by welding between this center frame and the charge of oil pipe realizes being connected sealing, can realize that also connection seals by the method for encrypting the packing material; This support bottom is slight K/UP shape, in order to rely on support air bag;
Described center frame upper end also is provided with position-limited rack, and it plays the effect of supporting the entrucking arm simultaneously in order to the degree that stretches into of restriction charge of oil pipe in the tank car oil inlet.
Described air bag is by hanging subsides or screw retention on this center frame, and it can realize radial expansion when inflation or venting; Described air bag is made by oil resisting material, in the form of a ring;
Also be connected with a flexible pipe and an exhausr port on the described air bag, an other end of this flexible pipe links to each other with pressurized air by a triple valve, and another outlet of this triple valve is an exhausr port; The conciliation triple valve can be implemented inflation and the venting to air bag.
The air sac sealing device that the utility model provides, its working process is as follows:
When tank car began charge of oil, this moment, air bag was in contraction state, inner not inflation, after the charge of oil pipe stretched into the tank car oil inlet and reach certain depth, position-limited rack is rested on the tank car oil inlet outer, to support whole entrucking arm, it is fixed, open triple valve, close exhausr port, introduce pressurized air, air bag is put on the air, make its radial expansion, be full of space between oil inlet and center frame until whole air bag, compress tank car oil inlet inwall well, realize sealing; Open inlet valve this moment again, and oil begins to enter tank car by the charge of oil pipe.Owing to realized sealing with air bag, the oil gas in the car can only be discharged into exhaust from the attached extraction pipe of charge of oil pipe and clean tower, and can not leak from elsewhere again.The tank car charge of oil is closed inlet valve after finishing, and closes the air bag triple valve again and opens exhausr port, and air bag is exitted, and makes its contraction, extracts the charge of oil pipe again out, closes tank car oil-feed flap at last, finishes tank car charge of oil process.
The air sac sealing device that the utility model provides in the charge of oil process, under the prerequisite of effective Expansion sealing of guaranteeing elastic bag, can be realized compressed-air actuated low pressure operation; When gas in the tank car builds the pressure above gasbag pressure, air bag outwards can be ejected, guarantee tank car safety.
The air sac sealing device that the utility model provides, it will seal the position and change into the oil inlet inboard, avoid outer various other annexes of tank car oil inlet, and good seal performance can prevent that oil gas from leaking, and reduces the pollution to surrounding environment and air.
Description of drawings
Fig. 1 is the structural representation of the air sac sealing device that provides of the utility model.
The specific embodiment
Following according to Fig. 1, a kind of preferred forms of the present utility model is described.
As shown in Figure 1, the structural representation of the air sac sealing device 1 that provides for the utility model, it comprises air bag 101 and center frame 102;
Described center frame 102 is installed in the lower end of tank car metal arm charge of oil pipe 2, and the method by welding between this center frame 102 and the charge of oil pipe 2 realizes being connected sealing, can realize that also connection seals by the method for encrypting the packing material; These center frame 102 bottoms 1021 are slight K/UP shape, in order to rely on support air bag 101;
Described center frame 102 upper ends also are provided with position-limited rack 103, and it plays the effect of supporting the entrucking arm simultaneously in order to the degree that stretches into of restriction charge of oil pipe 2 in tank car oil inlet 104.
Described air bag 101 is by hanging subsides or screw retention on this center frame 102, and it can realize radial expansion when inflation or venting; Described air bag 101 is made by oil resisting material, in the form of a ring;
Also be connected with a flexible pipe 1011 and an exhausr port (not illustrating in the drawings) on the described air bag 101, an other end of this flexible pipe 1011 links to each other with pressurized air by triple valve 1012; Triple valve 1012 has an outlet in addition for exhausr port, can implement inflation and venting to air bag 101 by regulating triple valve.
The air sac sealing device 1 that the utility model provides, its working process is as follows:
When tank car begins charge of oil, this moment, air bag 101 was in contraction state, inner not inflation, after charge of oil pipe 2 stretched into tank car oil inlet 104 and reach certain depth, position-limited rack 103 is rested on the outer of tank car oil inlet 104, support whole entrucking arm, it is fixed, open triple valve 1012, close exhausr port, introduce pressurized air, air bag 101 is put on the air, make its radial expansion, be full of the space of 102 of oil inlet 104 and center frames until whole air bag 101, well compress tank car oil inlet 104 inwalls, realize sealing; Open inlet valve this moment again, and oil begins to enter tank car, owing to realized sealing with air bag 101, the oil gas in the car can only be discharged into exhaust from charge of oil pipe 2 attached extraction pipes 201 and clean tower, and can not leak from elsewhere again.The tank car charge of oil is closed inlet valve after finishing, and closes triple valve 1012 again and opens exhausr port, and air bag 101 is exitted, and makes its contraction, extracts charge of oil pipe 2 again out, closes tank car oil-feed flap at last, finishes tank car charge of oil process.
