High altitude discharge afterwards.According to new standard requirement, core air cleaning system wind quantity test is needed respectively in initial resistance of filter and end
Carried out under resistive state, it is also longer with filter clogging effect test interval for being carried out before charging because the air balance cycle is longer,
Therefore during debugging, because of factors such as factory building and environmental conditions, if can be easily by moisture, dust, oil after filter installation
Paint etc. the influence of factor and fail.And the price of filter is higher, therefore debugging cost is higher.Current each nuclear power station is being adopted
When purchasing filter can more one times of buyings filters as debugging filter, after the completion of debugging, filter, which is scrapped, not to be used,
Add high equipment, artificial and post processing expense.How the initial resistance of different model filter and whole resistance are simulated, both
Ensure core cleaning system test method and result of the test, while reducing debugging cost is urgently solved in current nuclear power plant system debugging
Certainly the problem of.
The content of the invention

Described framework flange is integrally formed with framework.
The advantageous effects of the present invention are：The analogue means of the present invention is by switching with varying number bar hole
Adjustable plate realizes the Resistance Value under analog filters different conditions, and the analogue means is simple in construction, and it is convenient to change, and long-term use is not
Resistance can be caused to change, it is reusable to system cleanliness factor without particular/special requirement.Compared with conventional method, equipment cost and people
Work cost is greatly lowered, and simulated resistance is more precise and stable, and solving can not mould in nuclear power plant system debugging at this stage
The problem of intending whole resistance, greatly reduce the time in debugging process and debug the expense that spare part is consumed.
