Background
During debugging or overhaul of a nuclear power station, a containment isolation valve needs to be subjected to a tightness test, a formal blind plate at the downstream of a pressure leading pipeline needs to be removed before the test, and then a test blind plate which is consistent with the formal blind plate in size and used for pressurizing is installed, as shown in fig. 1. Meanwhile, the PVC hose is inserted into the pressurizing blind plate joint, so that a prerequisite is created for the measurement of the leakage rate of the subsequent isolation valve.
After the installation of the test blind plate is completed, the arrangement of the pressure-leading pipelines in part of test projects is close to the ground, the wall side and other pipelines, so that the process that a tester inserts the PVC hose into the blind plate interface is very inconvenient, the hose is easy to bend, the medium flow channel is separated, and the pressurizing is blocked.
Therefore, it is necessary to design a pressurization blind plate for a containment isolation valve tightness test to solve the above problems.

the pressurizing main board is provided with a screw hole, and a bolt penetrates through the screw hole and is fixed by a nut, so that the pressurizing main board is tightly matched with the inlet of the test pipeline.
And a sealing ring groove is processed at the center of the bottom surface of the pressurizing main board around the pressurizing hole and used for assembling a sealing ring to ensure the sealing performance of the pressurizing main board matched with the inlet end of the test pipeline.
And a hose joint is arranged at the other end of the pressurizing pipeline.
The pressurizing pipeline is a bent pipe, so that a hose can be conveniently inserted in the pressurizing pipeline.
The size of the pressurizing main board is consistent with that of the formal blind board.
The number of the screw holes is three or more, and the screw holes are machined on the pressurizing main board at equal intervals along the circumferential direction.
