Abstract

PURPOSE: To promote safety and prevent entering of rain water in a captioned hatch by providing a flange at the opening part of a pressure tank and an inner rim on the circumferential inner edge of a lid for pushing the inner rim to the back face of the flange to close the lid by the inner pressure of the tank.
CONSTITUTION: An opening 2 of a pressure tank 1 is provided with an upwardly eccentric flange 4 constructed of an upper flange 4a and a lower flange 4b. The flange 4 is provided with a stepped circumferetial rim (l) and a drop part (m), and an annular packing 6 is circularly applied to the stepped circumferential rim (l). Meanwhile, an inner rim 7 is circularly provided inward from the inner edge of a circumferential rim 3b of a lid plate 3a of a lid 3. When the lid 3 is closed, the lid plate 3a is pushed by the inner pressure P of the tank 1, and the inner rim 7 is hermetically pressed to the stepped circumferential rim (l) with the interposed annular packing 6 for preventing entering of rain water from the opening 2. Since the lid 3 is suspended and supported by a leaf spring 9 extended from a swing post 10, it can be easily opened or closed.
