Abstract
A kind of valve type radioactive source screening device relates to nuclear radiation protection and applied nuclear technologies field.Apparatus of the present invention comprise valve body and spool.Its design feature is, rabbets shield in the described valve body, can put into radiographic source in the shield and radiogenic beam is penetrated along the set through hole of shield.Described spool and through hole are vertically set in the valve body, and spool is provided with the beam passage identical with the through-bore axis direction.One end of spool and the compressing mechanism apical grafting that is arranged in the valve body, the other end of the spool thrust mechanism outer with being arranged on valve body is connected.When the radiographic source off working state, block through hole at the effect bottom spool of compressing mechanism and make the radiographic source sealing.When the radiographic source duty, over against through hole radiographic source is opened at the passage of the effect bottom spool of thrust mechanism.Compare with prior art, the characteristics that the present invention has is simple in structure, volume is small and exquisite can realize the standardization and the parametrization of shield assembly, and utilize the external structure of standard to satisfy the integrated requirement of multi-source body.
Description
Technical field
The present invention relates to nuclear radiation protection and applied nuclear technologies field, particularly the valve formula device that radioactive source is shielded.
Background technology
In the applied nuclear technologies field, be a very important link to the radiological safety protection of radioactive source and shielding, the unlatching design of ray, its security system is far longer than the designing requirement to other Mechatronic Systems.In the application of present radioactive source, normally provide radioactive source is done the source body that mechanical strength supports by the production base, the user offers the production base with the shielding construction body that designs, and radioactive source is put in the shielding construction body used for the user.The whole process of circulation wastes time and energy, and can't realize the industrialization production of shield assembly.There is potential safety hazard in conventional shielding, the opening ways by driven by motor lid door or goal realization ray that adopts, in the use when electrical fault, mechanical fault or power fail occurring, need manually overhaul and get rid of, can operating personnel's personal safety be constituted a threat to.And the shielding construction of this complexity is unfavorable for realizing that the high precision multi-source body of little locus is integrated.
Summary of the invention
At above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of valve type radioactive source screening device.It is simple in structure, volume is small and exquisite, can realize radiogenic sealing and unlatching safely, reliably, and can realize the standardization and the parametrization of shield assembly, satisfies the integrated requirement of multi-source body.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes as follows:
A kind of valve type radioactive source screening device, it comprises valve body and spool.Its design feature is, rabbets shield in the described valve body, can put into radiographic source in the shield and radiogenic beam is penetrated along the set through hole of shield.Described spool and through hole are vertically set in the valve body, and spool is provided with the beam passage identical with the through-bore axis direction.One end of spool and the compressing mechanism apical grafting that is arranged in the valve body, the other end of the spool thrust mechanism outer with being arranged on valve body is connected.When the radiographic source off working state, block through hole at the effect bottom spool of compressing mechanism and make the radiographic source sealing.When the radiographic source duty, over against through hole radiographic source is opened at the passage of the effect bottom spool of thrust mechanism.
In above-mentioned shield assembly, described compressing mechanism is a thrust spring, and described thrust mechanism is an electromagnet.
In above-mentioned shield assembly, described valve body, spool all adopt the material of maskable ray to make.
The present invention is owing to adopted above-mentioned structure, and the passage of spool is over against through hole when normally using, and the beam passage is opened, and spool blocks through hole under the effect of compressing mechanism when finishing using back or power fail, has effectively shielded ray, has ensured personnel's safety.Compare with prior art, the characteristics that the present invention has is simple in structure, volume is small and exquisite can realize the standardization and the parametrization of shield assembly, and utilize the external structure of standard to satisfy the integrated requirement of multi-source body.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
The structural representation of Fig. 1 during for closed state of the present invention;
The structural representation of Fig. 2 during for opening of the present invention.
Embodiment
Referring to Fig. 1 and Fig. 2, the present invention includes valve body 5 and spool 2 that the material that adopts the maskable ray is made.Interlocking shield 3 in the valve body 5 can be put into radiographic source 4 and the beam of radiographic source 4 is penetrated along shield 3 set through holes 8 in the shield 3.Spool 2 is vertically set in the valve body 5 with through hole 8, and spool 2 is provided with the beam path 10 identical with through hole 8 axis directions.One end of spool 2 and the compressing mechanism 6 thrust spring apical graftings that are arranged in the valve body 5, the other end of spool 2 be arranged on valve body 5 thrust mechanism 1 electromagnet outward and be connected.When radiographic source 4 off working states, block through hole 8 at the effect bottom spool 2 of compressing mechanism 6 and make radiographic source 4 sealings; When radiographic source 4 duties, over against through hole 8 radiographic source 4 is opened at the path 10 of the effect bottom spool 2 of thrust mechanism 1.
Apparatus of the present invention are when off working state, and electromagnet outage is blocked through hole 8 at the effect bottom spool 2 of thrust spring and made radiographic source 4 sealings, as shown in Figure 1.Beam passage complete closed, radiographic source 4 is reliably shielded.During use, connect the power supply of electromagnet, at the path 10 of the effect bottom spool 2 of electromagnet the beam of radiographic source 4 is penetrated along through hole 8, as shown in Figure 2.
When using apparatus of the present invention to realize that the multi-source body is integrated, can adopt multiple arrangement to make up and get final product.
In addition,, utilize electromagnet that locking device is set spool is pinned when being in closed state for the present invention, suchlike technical scheme also belongs to the scope of protection of the invention.
