Description
Technical field
It is that a kind of high-performance for MRI screened rooms is opened flat air pressure shielding soundproof door the present invention relates to be electromagnetically shielded field.
It is specifically a kind of to switch the vertical hinged door easily as house door with superpower electromagnet shield effect and sound insulation.
Background technology
MRI screened rooms apply to the radio shielding of permanent magnetism and superconduction nuclear magnetic resonance equipment, prevent external electromagnetic field from disturbing
The normal work of NMRS imager (MRI), while suppressing the extraneous instrument and equipment of magnetic field exposure influence that MRI is produced
Normal work.
The slot leakage of screened room determines shield effectiveness, and the function of shielding soundproof door is that the leakage in solution activity gap is asked
Topic, its performance greatly influences the efficiency of screened room.Existing high-performance air pressure shielding soundproof door is a kind of parallel-moving type shielding sound insulation
Door, is not suitable for MRI screened rooms, because there are safety risks：When quenching, door is difficult to open.Not yet have for nuclear-magnetism at present
Resonance MRI shields the air pressure vertical hinged door of computer room.
There is following defect in the manual vertical hinged door of existing MRI screened rooms：
(1) shielding construction is that squash type reed, i.e. door leaf are shielded with doorframe activity gap using finger-type reed, shield effectiveness
The deformation extent of reed is depended primarily on, deformation extent is bigger, and extruding force is bigger, the service life of door is shorter, switched more laborious！
Conversely, switch is laborsaving, shield effectiveness is then lower！Can not meet the demand of use requirement and client.
(2) finger-type reed is chronically at forced compression state, and elasticity can be reduced, after plastic deformation contact significantly under
Drop, ordinary circumstance useful life was not over 3 years.The Quality Down of soundproof door is shielded, causes the decline of screened room shield effectiveness,
Necessarily cause image resolution ratio to decline fuzzy, greatly affected the use quality of magnetic resonance equipment, user can be misinterpreted as magnetic and be total to
The equipment quality that shakes is deteriorated, and makes us being entangled with vexatious, have impact on the reputation and income of hospital！
(3) fault rate is high in use, for example：Reed is damaged, and door leaf deformation, hinge deformation, switch gate is laborious, shield effectiveness
Decline/unstable, poor quality images etc..
(4) the finger-type reed pressure of existing structure is unadjustable, can guarantee that certain shield effectiveness, certainly will change spring
Piece, increases maintenance cost, while also having influence on the normal earning of hospital.
