Description
Technical Field
The invention relates to an effective radiation intensity spatial distribution indicator of a directional X-ray flaw detector, belonging to the technical field of nondestructive testing and industrial rays.
Background
GB/T26833-2011 "X-ray tube general technical conditions for nondestructive testing instrument industry" stipulates that the effective beam angle is greater than 38 degrees. At present, the radiation angle of the directional X-ray flaw detector is generally 40 °, and the radiation angle of the circumferential X-ray flaw detector is generally 24 ° X360 °.
At present, the X-ray tube used for industrial detection or medical detection at home and abroad has a thicker anode target surface, which is called as a thick target X-ray tube, and when high-speed electrons bombard the target surface, the X-ray tube not only interacts with target atoms to radiate X-rays, but also penetrates to a certain depth in the target. Therefore, in addition to the irradiation of the X-rays on the target surface, the X-rays can be generated also in the deep layer of the target. The deeper the layer the more X-rays generated are absorbed by the anode side anode target itself and the smaller the target angle the greater the degree of degradation. This decrease in the intensity of the X-rays distributed along the tube axis, which is closer to the anode, results in a phenomenon in which the intensity on the cathode side is higher than on the anode side, the so-called "heel effect", also called anode effect or roll effect.
The amount of radiation intensity of X-rays emitted from the anode target at different azimuthal angles is not uniform, referred to as the spatial distribution of radiation intensity. Uneven intensity distribution of the rays can cause uneven blackness of the negative, interfere with observation and evaluation of the negative, and cause overlooked defect images to be too deep or too shallow. Currently, directional X-rays are not equipped with reasonably suitable indicators of the spatial distribution of radiation intensity.
Disclosure of Invention
The invention provides an effective radiation intensity spatial distribution indicator of a directional X-ray flaw detector, aiming at solving the problems that when transillumination is arranged, the film is placed outside radiation, so that the film shooting is incomplete, the blackness of the film image is not uniform due to unclear X-ray machine radiation distribution, and the optimal radiation field distribution can be clearly displayed when a workpiece with higher image requirement is inspected, so that the film image quality is improved.
The invention provides an effective radiation intensity spatial distribution indicator of a directional X-ray flaw detector, which comprises two rotating bearings, a rotating rod and a laser generator, wherein the two rotating bearings are respectively arranged at two sides of a ray window, the rotating rod is arranged between the two rotating bearings, the laser generator is arranged in the middle of the rotating rod, the two rotating bearings are driven by a driving device to drive the rotating rod to rotate so as to drive the laser generator to rotate, and the laser generator emits colored laser.
Preferably, the laser generator emits cone-shaped laser light.
Preferably, the laser generator emits a conical laser beam having a unilateral divergence angle of not more than 15 ° and a radiation angle of not more than 30 °.
The directional X-ray flaw detector effective radiation intensity spatial distribution indicator has the beneficial effects that:
the electromagnetic radiation field invisible to naked eyes is marked by the colored laser, the radiation field of the directional X-ray flaw detector can be continuously increased along with the increase of the focal length F, so that the effective radiation intensity spatial distribution of the directional X-ray flaw detector under different focal lengths F can be better displayed, and the use is convenient.

The laser generator 3 emits cone-shaped laser light. The laser generator 3 emits a conical laser beam having a single-sided spread angle of not more than 15 DEG and a radiation angle of not more than 30 deg. The driving device is controlled by a control system, and the laser generator 3 is controlled to rotate to the position right below the ray window 2 from the side.
The specific operation process of the effective radiation intensity spatial distribution indicator of the directional X-ray flaw detector comprises the following steps:
fig. 1 shows the position of the indicator for the spatial distribution of the effective radiation intensity of the directional X-ray flaw detector when the indicator is not used or is used, the indicator is rotated to a position completely away from the ray window 2, the radiation of rays from the ray window 2 cannot be blocked, the indicator is rotated to the position shown in fig. 2 when the indicator is used, namely the position right below the ray window 2, the colored laser generator 3 is positioned at the center of the window, the axis of the conical laser beam is vertical to the window, and thus the area displayed by the laser beam on the ground or a workpiece is the spatial distribution of the effective radiation intensity of the directional X-ray flaw detector.
The invention relates to an effective radiation intensity spatial distribution indicator of a directional X-ray flaw detector, which is designed to be erected on a window of the X-ray flaw detector and used for displaying the spatial distribution of the effective radiation intensity of the X-ray detector when a radiographic film is arranged for radiographic inspection, and can be turned away when the X-ray is transilluminated, so that the effective radiation intensity spatial distribution indicator does not block the emission of rays.
