Abstract
The utility model discloses a radiographic testing device for testing cracks of a pipeline. The radiographic testing device comprises a working platform and a gamma-ray source, wherein a clamp used for fixing a pipeline with cracks is arranged in the working platform, an opening is formed in one end of the working platform, a placing groove used for placing a film is formed in the other end of the working platform and corresponds to the opening, the opening is communicated with the placing groove through a light-transmitting channel, and the gamma-ray source is opposite to the opening in the working platform. The radiographic testing device has the beneficial effects of simple structure and high testing precision.
Description
Technical field
The utility model relates to the pipe surface measuring technique, particularly a kind of ray detecting apparatus for detection of pipe crack.
Background technology
In daily productive life; the surface of pipeline often trickle crack or scratch can occur; due to this crack with wipe to give birth to very trickle; the basic None-identified of naked eyes; if but will come into operation with crack or abrasive pipeline; will bring hidden danger to safety in production, therefore the detection for pipe surface is very important.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to have designed a kind of ray detecting apparatus for detection of pipe crack.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of ray detecting apparatus for detection of pipe crack, comprise worktable and r radiographic source, be provided with the jig for fixed band slit-tube road in worktable, an end at worktable is provided with opening, the position that the other end is corresponding with opening is provided with the standing groove of placing film, and the channel connection by printing opacity between opening and standing groove, and the r radiographic source is relative with opening on worktable.
Described r radiographic source is Ir-192 type radiographic source.
Described film is the fine granularity film, preferred AGFAC7 film.
The ray detecting apparatus for detection of pipe crack that utilizes the technical solution of the utility model to make can be realized the accurate measurement of pipe crack, and is simple in structure, easy to maintenance, low cost of manufacture, and measuring accuracy is high.
Description of drawings
Fig. 1 is the structural representation of the ray detecting apparatus for detection of pipe crack described in the utility model;
In figure, 1, worktable; 2, r radiographic source; 3, jig; 4, opening; 5, standing groove; 6, film.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, it is the structural representation of the ray detecting apparatus for detection of pipe crack described in the utility model as Fig. 1, as shown in the figure, a kind of ray detecting apparatus for detection of pipe crack, comprise worktable 1 and r radiographic source 2, be provided with the jig 3 for fixed band slit-tube road in worktable, an end at worktable is provided with opening 4, the position that the other end is corresponding with opening is provided with the standing groove 5 of placing film 6, and the channel connection by printing opacity between opening and standing groove, the r radiographic source is relative with opening on worktable.Wherein, described r radiographic source is Ir-192 type radiographic source; Described film is the fine granularity film, preferred AGFAC7 film.
The characteristics of the technical program are to complete the testing in pipe surface crack by optical imaging concept, and accuracy of detection is high, and speed is fast, and simple in structure.Repairing can be changed at any time if equipment goes wrong, normal testing can be do not delayed.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; some changes that those skilled in the art may make some part have wherein all embodied principle of the present utility model, within belonging to protection domain of the present utility model.
