Description
Technical field
The present invention relates to the conveying device of neutron source, particularly a kind of reversing head structure of neutron source conduit.
Background technology
At the critical or subcritical assembly of nuclear industry, and other irradiation, measure in the industry, often can use neutron source.Neutron source is delivered to appointed positions by special conveyance conduit neutron is provided, and in test, often requires neutron source or radiation exposed sample to be transported in the radiation field rapidly, or the irradiation activation district that speeds away.Because neutron source and environment on every side have radioactivity, the general operation personnel can't closely operate, under this condition, need drive neutron source with pressurized air moves in conduit, and behind the test operation, need to neutron source carry out with on-test before reverse move operation, realize compressed-air actuated commutation.And in the present disclosed document, this reverse flow technique does not still have report on open source literature.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, provide a kind of simple in structure, easy and simple to handle, utilize pressurized air to realize the reversing head structure of the neutron source conduit that neutron source moves.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of reversing head structure of neutron source conduit, this device is cylindric, comprises cylinder, bulb, key is, column body has neutron source manhole appendix, air manhole appendix, and bulb is positioned at the neutron source manhole appendix of cylinder, and the neutron source manhole appendix is communicated with the air manhole appendix.
In order better to realize the translational speed of pressurized air to neutron source, the present invention is all right: described neutron source manhole appendix is communicated with the air manhole appendix by chamber.The diameter of described bulb equals the internal diameter of neutron source manhole appendix.Described bulb is a SDeflector.Described SDeflector is 2, places the neutron source both sides respectively.Described chamber is that cylinder end and end cap welding form chamber.Described chamber is that boring seals the formation chamber again on the cylinder.Neutron source manhole appendix end in the described cylinder is provided with projection.The surface of contact of described projection and bulb is an arc.。
Compared with prior art, the invention has the beneficial effects as follows: neutron source manhole appendix and the air manhole appendix of this device by on cylinder, having connection, promote the priming of bulb by pressurized air, and then realize moving of neutron source, this apparatus structure is compact simple, easy to operate, but and remote-controlled operation.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
A kind of reversing head structure of neutron source conduit, integral body is cylindrical, its middle chamber can have end cap 1 and cylinder 8 welding to form, and also can be that end cap 1 is integral with cylinder 8, directly adopt in cylinder 8 borings, and then the repair welding sealing forms.This enforcement is that example is illustrated the present invention to adopt end cap 1 and the chamber 2 that cylinder 8 welding form.
This device comprises cylinder 8, bulb 3a, 3b, and cylinder 8 inside have neutron source manhole appendix 5, air manhole appendix 6, and bulb 3a, 3b are positioned at the neutron source manhole appendix 5 of cylinder 8, and neutron source manhole appendix 5 is communicated with air manhole appendix 6 by chamber 2.The diameter of bulb 3a, 3b equals the internal diameter of neutron source manhole appendix 5, when making this bulb 3a, 3b can pass in and out neutron source manhole appendix 5, also can well realize compressed-air actuated sealing, prevent that pressurized air from spilling and influence the translational speed of neutron source 4 from the gap of neutron source 4 and neutron source manhole appendix 5.Present embodiment adopts SDeflector 3a, 3b as bulb 3a, 3b, and SDeflector 3a, 3b are the both sides that lay respectively at neutron source 4.In order better to realize the location of neutron source 4, cylinder 8 is provided with the arc convex 7 that contacts with SDeflector 3b in the reversing head structure in neutron source manhole appendix 5 ends.
During work, the external compression air system is connected with neutron source manhole appendix 5, and compressed air system provides pressurized air to promote SDeflector 3a and moves, and indirect promotion neutron source 4 enters the commutation head.After entering the commutation head, feed pressurized air by neutron source manhole appendix 5, the original air in neutron source manhole appendix 5, the chamber 2 is discharged by air manhole appendix 6.Under compressed-air actuated promotion, neutron source 4 is transported to assigned address, and SDeflector 3b is by projection 7 constraints, because the contact site of projection 7 and SDeflector 3b adopts arc contact surface, impact injury when preventing to brake or SDeflector 3b are stuck.In the time of neutron source 4 need being pushed away,, pressurized air is entered from air manhole appendix 6,, promote SDeflector 3b, promote neutron source 4 indirectly and leave the commutation head by chamber 2 by external compression air switching pressurized air airintake direction.That this device is implemented in by pressurized air is critical/subcritically wait the I/O that realizes in the device radioactive source, also can realize the test that speeds away behind the sample irradiation.
