Abstract
The utility model discloses a sodium iodide crystal's packaging structure package sodium iodide contains crystal, reflector layer, potassium chloride, optical glass, buffer body, an encapsulation section of thick bamboo, encapsulation cover, with the reflector layer encapsulation outside the crystal, again at reflector layer outside encapsulation potassium chloride, buffer layer, crystal top encapsulation optical glass for the ray arouses the produced light of sodium iodide crystal to pass through out to photomultiplier and receive. Fixed optical glass and an encapsulation section of thick bamboo and encapsulation cover are filled with sealed glue to aluminium was done for the total an encapsulation section of thick bamboo and the encapsulation of encapsulation cover.
Description
Technical field
This utility model relates to encapsulation technology field, the encapsulating structure of a kind of sodium iodide crystal.
Background technology
General sodium iodide crystal encapsulation, simply containing sodium iodide crystal, reflector layer, cushion, optics slide, encapsulation cylinder and encapsulation cover composition, need in actual use individually to add other radioactive sources calibration signal, and the light excited can not fully be utilized by photomultiplier tube, cause detection inaccurate, potassium chloride is directly encapsulated into outside sodium iodide crystal reflector layer by this structure, integral packaging, and on connecting cylinder, process screw thread, it is threaded connection, closely cooperate with photomultiplier tube connecting cylinder, so can solve signal calibration problem, and with connecting cylinder closely cooperates, can be with shading, solve leakage problem, it is threaded connection, crystal can quickly be carried out by actual production assemble screening test, improve production work efficiency.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, it is provided that the crystal packaging structure that a kind of packaging effect is good and production efficiency is high.
The technical solution of the utility model is: the encapsulating structure of a kind of sodium iodide crystal, this structure includes encapsulating cylinder and encapsulation cover, it is provided with sodium iodide crystal in encapsulation cylinder, surrounding reflecting layer outside sodium iodide crystal, filling chlorinated potassium outside reflecting layer, at sodium iodide crystal underfill cushion, optical glass is installed at sodium iodide crystal top, encapsulation cylinder and encapsulation cover encapsulation fluid sealant are fixed, and at encapsulation cylinder top car encapsulation cylinder screw thread, and the corresponding pedestal that connects is fixed.
Encapsulation cylinder is threaded, is threadedly secured to connect on pedestal accordingly.
Encapsulation cylinder aluminum barrel encapsulates, surface oxidation blasting treatment.
The utility model has the advantage of: potassium chloride is directly encapsulated into outside sodium iodide crystal reflector layer by this structure, integral packaging, and on connecting cylinder, process screw thread, it is threaded connection, closely cooperate with photomultiplier tube connecting cylinder, so can solve signal calibration problem, and closely cooperate with connecting cylinder, can be with shading, solve leakage problem, it is threaded connection, quickly can carry out crystal assembling screening test in actual production, improve production work efficiency.
Accompanying drawing explanation
Fig. 1 is the encapsulating structure structural representation of a kind of sodium iodide crystal of this utility model.
Detailed description of the invention
A kind of encapsulating structure of sodium iodide crystal, reflecting layer 5 is surrounded outside sodium iodide crystal 2, filling chlorinated potassium 4 outside reflecting layer 5, at sodium iodide crystal 2 underfill cushion 7, install optical glass 1 at sodium iodide crystal 2 top, entirety encapsulation cylinder 6 and encapsulation cover 8 encapsulate, and fix with fluid sealant, at encapsulation cylinder 6 top car encapsulation cylinder screw thread 3, and the corresponding pedestal that connects is fixed.This structure, according to detection demand integral packaging, facilitates background radix to verify.
The encapsulating structure of a kind of sodium iodide crystal, encapsulation cylinder, according to the photomultiplier tube model joined, exceedes photomultiplier tube region and arranges reflector layer in optical glass position, makes full use of ray and excites light produced by sodium iodide crystal to receive for photomultiplier tube；The upper processing screw thread of encapsulation cylinder, whole integrative-structure is threaded according to specifically used and corresponding connection pedestal, it is also possible to connects with fixing cylinder and connects fixing crystal in other ways.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
