Description
Technical field
The utility model relates to a kind of entrucking oil filling riser, relates in particular to the flexible nanubrium of entrucking oil filling riser.
Background technology
When highly volatile liquid such as loading and unloading gasoline etc., need to adopt entrucking under the liquid, at the bottom of namely the nanubrium of oil filling riser will reach jar; Need again after having adorned nanubrium is extracted from high car.For easy to use, nanubrium must be made two telescopic joints, carry out entrucking at the bottom of can reaching when namely slip joint stretches out jar, can in tank car, extract easily during the slip joint withdrawal.
The more flexible nanubrium that uses has manual type and two kinds of structures of vertical counter weight type now.As shown in Figure 1, the flexible nanubrium of manual type by interior pipe 11 ', outer telescopic pipe 12 ', lift system 13 ', steel rope 14 ' etc. form, be that pipe is fixing in adopting, the traction of outer effective steel rope is connected on the nanubrium elbow, rotates the lifting that handwheel is realized projecting tube.When operating, the workman wastes time and energy, and very inconvenient, and the fault rate height.
As shown in Figure 2, the flexible nanubrium of plummet counter weight type by outer tube 21 ', interior telescopic pipe 22 ', plummet 23 ', fixed pulley 24 ', steel rope 25 ' etc. form, plummet links to each other with interior telescopic pipe by fixed pulley with the steel wire rope, utilize the weight of telescopic pipe in the highdensity plummet balance, realize automatic lifting.But the too big flow area that influences of plummet volume first, two come plummet can vibrate pipe in the bump when flow of liquid, and plummet easily breaks fixed pulley when rising in addition, the fault rate height, needing often stops production keeps in repair.
The utility model content
Technical problem to be solved in the utility model is: the automatically flexible nanubrium that a kind of entrucking oil filling riser easy to use, non-damageable is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of flexible nanubrium of entrucking oil filling riser, comprise the outer tube that is fixedly installed on the oil filling riser body liquid outlet, the fixed mount that is located at oil filling riser body liquid outlet place, activity is equipped with the interior pipe of bottom sealing in the outer tube, be provided with at least one fluid hole near the bottom on the inner pipe wall, fixed mount is provided with extension spring, and the other end of extension spring is connected with interior pipe bottom.
The position that the liquid outlet of described oil filling riser body is between fixed mount and the interior pipe is provided with crashproof ring.
The pipe bottom is provided with collision chock in described.
Described outer wall of inner tube is provided with some guide rings.
The inwall bottom of described outer tube is provided with terminal guide ring and lower seal.
The outer wall top of pipe is provided with seal ring in described.
Outlet end is provided with butt flange on the described oil filling riser body, and described outer tube links to each other with butt flange by the end flange that its top arranges.
Described end flange material is aluminium.
The beneficial effects of the utility model are: because activity is equipped with the interior pipe that the bottom is sealed in outer tube, the fixed mount at oil filling riser body liquid outlet place is provided with extension spring, and the other end of extension spring is connected with interior pipe bottom.When entrucking, along with flow rate of liquid slowly increases, the gravity of liquid and impulsive force sum slowly increase, and when increasing to when overcoming tension spring tension interior pipe are released, and liquid flows in the car from fluid hole.After entrucking finishes, valve closing, along with after liquid in the pipeline drops down from interior pipe lower end, pipe gravity retracted interior pipe in the outer tube in extension spring overcame.Thereby make the utility model realize entrucking under hydrodynamic.
Because interior pipe is provided with guide ring, can not take place crooked when pipe slides in outer tube in making;
Because the liquid outlet of oil filling riser body is in the crashproof ring that the below of fixed mount is provided with elastic material, interior pipe bottom is provided with the collision chock of elastic material, and pipe with oil filling riser body or jar end hard collision takes place in effectively preventing.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 3, a kind of flexible nanubrium of entrucking oil filling riser, comprise the outer tube 2 that is fixedly installed on oil filling riser body 1 liquid outlet, activity is equipped with the interior pipe 3 of bottom sealing in the outer tube 2, the outer wall top of interior pipe 3 is provided with seal ring 4, the inwall bottom of outer tube 2 is provided with terminal guide ring 5 and lower seal 6, and interior pipe 3 outer walls are provided with some guide rings 7.Be provided with at least one fluid hole 8 near the bottom on interior pipe 3 tube walls, described interior pipe 3 bottoms are provided with the collision chock 9 of elastic material.Oil filling riser body 1 liquid outlet place is provided with fixed mount 10, and fixed mount 10 is provided with extension spring 11, and the other end of extension spring 11 is connected with interior pipe 3 bottoms, and the pulling force of extension spring 11 is greater than the gravity of interior pipe 3.The below that the liquid outlet of described oil filling riser body 1 is in fixed mount 10 is provided with the crashproof ring 12 of elastic material.Outlet end is provided with butt flange 13 on the described oil filling riser body 1, and described outer tube 2 links to each other with butt flange 13 by the aluminium matter end flange 14 that its top arranges.
