Gas-fluid-sound isolation door assembly with integral testing means
摘要:
The specification discloses an isolation door assembly which, by virtue of having annuli provided about the joint between the door coaming and the door framing, about the seal between the door and the coaming, and about any penetration of the door by shafts, etc. provides the means to test the door assembly at installation, and at specified testing intervals.By providing pressure fittings (normally plugged) which communicate with the annuli described above, and introducing a testing medium under pressure into said annuli, the integrity of all door seals can be tested.
