Background
The rod anode X-ray flaw detector is mainly applied to nondestructive testing of the quality of an inner hole welding seam of a tube plate and is more and more widely popularized and applied. The working principle is as follows: an anode rod containing an anode target extends into the hollow tube, and electrons generated by the cathode filament bombard the anode target under the action of a high-voltage electric field to generate X rays which penetrate through a welding line of the detection tube plate. During the X-ray tube work, the positive pole target can produce a large amount of heats in the positive pole stick, influences X ray source stability and durable degree, for making detection achievement normal clear, the operating specification requirement is according to 1: the mode 2 operation, namely, the exposure time is 1 minute, the natural cooling time is 2 minutes, and then the next detection is carried out, and the detection is carried out according to the circulation. Therefore, the detection efficiency is low.
In the prior art, a water cooling structure is adopted, and cooling media circularly flow to take away heat. The method needs to additionally add equipment such as a cooling water source and the like, and changes the rod anode structure, so that the manufacturing cost is increased, the complexity of field operation is increased, and the technical problem of incomplete cooling exists.
Disclosure of Invention
The invention aims to solve the problem of how to avoid the accumulation of the detection work heat of the X-ray tube, so that the subsequent detection is not influenced, the detection efficiency is greatly improved, and the invention provides the rod anode X-ray tube capable of continuously detecting.
The application provides a rod anode X-ray tube technical scheme capable of detecting uninterruptedly, and the main technical contents are as follows: a rod anode X-ray tube capable of uninterrupted detection comprises a tube body and an anode rod thereof,
the anode rod is radially fixed on the main body of the ray tube by a flange assembly at one side and the root of the main body of the ray tube;
the flange assembly is provided with a wind cooling part;
the air cooling part comprises an air nozzle, a nozzle and an air nozzle communicated between the air nozzle and the nozzle, and is connected and installed on the peripheral side of the flange assembly;
the nozzle is arranged on the outer surface of the flange assembly and faces the position of the anode target in the anode rod;
the air duct is arranged inside the flange assembly and communicated with the air nozzle and the nozzle.
In a preferred embodiment of the above overall technical solution, the number of the nozzles is at least 2, the nozzles are symmetrically arranged with the anode bar as a center, the air ducts are communicated with the nozzles, and the other ends of the nozzles are collected and communicated to the air nozzles.
In a preferred embodiment of the above overall technical solution, the flange assembly is formed by fixing a flange seat and a flange end cap, wherein the flange seat is fixed to an anode bar mounting opening of a shell of the tube body; the middle section of the air duct is positioned in the flange seat and the flange plate end cover, and after the flange seat and the flange plate end cover are fixedly assembled, the respective air duct sections are communicated to form the air duct.
The utility model discloses a but stick positive pole X-ray tube technical scheme of incessant detection utilizes the air compressor equipment that the job site is equipped with always, make and be linked together with the air cock on the X-ray tube, compressed air blows to positive pole target place by the nozzle on the positive pole stick mounting flange assembly, continuously take away the heat that its work produced, for its cooling, therefore can accomplish the next detection at once after detecting, and need not to wait for the natural cooling time, the detection operation can go on in succession, the detection operation efficiency has been improved by a wide margin, still have the comprehensive technical advantage of cooling.
