ABSTRACT:
A novel device for closing the dome of a tank with gravity and/or pneumatic discharge, comprising a closure cap member which is applied against a seat provided with a resilient sealing gasket, and a closure mechanism for holding the cap member on the seat, wherein the cap member comprises a protection cap provided with fixing means for the closure mechanism and a bearing surface whose surface is a surface of revolution and which is formed by at least one segment of a straight line and/or arc of a curve, wherein the seat comprises a support plate acting as an abutment for the bearing suface of the cap member, a resilient gasket which is loaded in bending by contact with the bearing surface of the cap member, and a co-operating flange for fixing the gasket on the support plate, and wherein the closure mechanism is operable with a low mechanical force.
The novel dome closure device is self-cleaning, self-sealing, operable with a low force, capable of being automated and having a high degree of safety for the operator.
