Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Important component of the access lock as nuclear reactor safety shell pressure boundary, in normal reactor operation operating condition
And ensure the integrality and leakproofness of containment pressure boundary during misoperation operating condition.It is used as reactor shutdown under normal circumstances
During reloading and running, operation maintenance personal passes in and out the channel of containment, can pass through the operated manually or electrically real of transmission mechanism
The opening and closing of existing gate.Under compactedness nuclear reactor arrangement condition, while needing to have function of shielding.As shown in Figure 1,
One embodiment of the invention provides a kind of difunctional access lock of shield gasket, inside cabin panel assembly 4, outer mainly by cylinder assembly
Cabin panel assembly 1, outer side seal door component 6, inside shield gasket door component 7, interior transmission case 5, middle part transmission case 3, outer transmission
The composition such as case 2 and coupling spindle.Cylinder is used as personnel and passes in and out current channel, while having and connecting inside and outside cabin panel assembly
Effect forms the environment of a sealing.Outside closed door and inside shield gasket door play isolation in normal reactor operation
The effect of containment interior or exterior space prevents pernicious gas and radioactive substance leakage in containment.Inside and outside transmission case and middle part pass
Dynamic case is connected by coupling spindle, forms complete transmission system, realizes access lock interlocking, balanced valve, door lock and hermatic door
The operation such as successively open or close.
Shield gasket door configures corresponding shielding material and shielding thickness according to the gentle requirement of reactor radioactive water.
The operation and use of above equipment:
Access lock outside, middle part, outside transmission case cooperate other transmission parts, can carry out to entire access lock complete
The feature operation in orientation.Top handwheel can operate proximal seal door, and lower part handwheel can seal distal side by transmission shaft
Door is operated.
When enabling, operator operates inside, outside transmission case top handwheel, completes interlocking, balanced valve, door lock, sealing
