Description

Technical Field

[0001] This patent application relates to a rod anode X-ray flaw detector, and more particularly to the rod anode X-ray tube of the rod anode X-ray flaw detector. Background Technology

[0002] Rod-type anode X-ray flaw detectors are mainly used for non-destructive testing of weld quality in the inner bores of tubes and tube sheets, and their application is becoming increasingly widespread. Their working principle is as follows: an anode rod containing an anode target is inserted into an empty tube. Under the influence of a high-voltage electric field, electrons generated by the cathode filament bombard the anode target, producing X-rays that penetrate and inspect the weld seam of the tube sheet. During operation, the anode target generates a large amount of heat within the anode rod, affecting the stability and durability of the X-ray source. To ensure normal operation, the operating procedure requires a 1:2 ratio, meaning that after every minute of exposure, the tube needs to cool naturally for two minutes before the next test, and this cycle is repeated. This results in relatively low testing efficiency.

[0003] Existing technologies employ water-cooling structures, where the cooling medium circulates to remove heat. This method requires additional equipment such as a cooling water source and modifications to the rod anode structure, increasing manufacturing costs, adding complexity to on-site operations, and also presenting technical problems with incomplete cooling. Summary of the Invention

[0004] The purpose of this patent application is to solve the problem of how to avoid the accumulation of heat during X-ray tube detection, so as not to affect subsequent detection and to greatly improve detection efficiency, by providing a rod anode X-ray tube that can perform uninterrupted detection.

[0005] The technical solution for a rod anode X-ray tube capable of uninterrupted detection provided in this patent application mainly includes: a rod anode X-ray tube capable of uninterrupted detection, comprising a tube body and its anode rod.

[0006] The anode rod is radially fixed to the ray tube body from one side and at its root by a flange assembly.

[0007] The flange assembly described herein includes an air-cooled section;

[0008] The aforementioned air-cooling unit comprises an air nozzle, a spray nozzle, and an air duct connecting the air nozzle and the spray nozzle.

[0009] The air nozzle is connected and installed on the periphery of the flange assembly;

[0010] The nozzle is located on the outer surface of the flange assembly and faces the anode target inside the anode rod.

[0011] The air duct is located inside the flange assembly and connects the air nozzle and the nozzle.

[0012] In one preferred embodiment of the above overall technical solution, the number of nozzles is at least 2, symmetrically arranged around the anode rod, and the other end of the air duct communicating with each nozzle is converged and connected to the air nozzle.

[0013] In one preferred embodiment of the above overall technical solution, the flange assembly is fixedly composed of a flange seat and a flange end cover, wherein the flange seat is fixed to the anode rod mounting port of the X-ray tube body shell; the air duct is located in the middle of the flange seat and the flange end cover, and after the flange seat and the flange end cover are fixedly assembled, their respective air duct sections are connected to form an air duct.

[0014] The X-ray tube technology for uninterrupted testing of rod anodes disclosed in this patent application utilizes an air compressor commonly available at the work site, which is connected to the air nozzle on the X-ray tube. Compressed air is blown from the nozzle on the anode rod fixing flange assembly to the location of the anode target, continuously removing the heat generated during operation and cooling it down. Therefore, the next test can be performed immediately after the completion of one test without waiting for natural cooling time. The testing operation can be carried out continuously, which greatly improves the efficiency of the testing operation and also has the technical advantage of comprehensive cooling.
