Embodiment Construction

[0023] The assembly of the present invention provides fluid communication between the exterior and interior chambers of the pressure vessel while maintaining the integrity of the pressure vessel and isolating the pressurized gas chamber of the pressure vessel from the inner liquid holding chamber. Isolating the pressurized gas chamber from the inner chamber provides a change in pressure without being affected by atmospheric pressure outside the pressure tank.

[0024] The outer wall of the tank 12 is preferably a steel shell formed in three sections, a top cover 28, a central cylinder 26 and a lower cup 18 formed of steel or other rigid, preferably metallic material. . Supported within the outer wall of the tank 12 is an inner liquid chamber defined by at least one flexible membrane 14 and a lower liner 16; the lower liner may be flexible or rigid, or can be at least partially fixed to the tank Lining of the inner surface of the outer rigid wall. The lower liner 16 is in tur...

Abstract

An air-tight and liquid-tight inlet connection to an inner chamber of a multi-chamber pressure vessel is provided that includes a male sealing gland extending through a hole in the bottom of the flexible wall of the inner chamber and the vessel the lower wall of the rigid outer shell, the male sealing gland includes: an upper flange permanently sealingly connected to the lower surface of the flexible inner wall so as to form an air-tight and liquid-tight seal therein; and a lower flange; an elongated member extending through the outer housing for sealing connection with the fluid inlet tube to allow fluid to flow into the inner chamber while maintaining a seal between the inner and outer chambers of the tank to allow fluid to enter the inner chamber Instead, the flexible wall is pushed up into the outer chamber to maintain pressurization in the outer chamber.

Description

technical field [0001] The present application relates to a new type of connection for providing an air-tight and liquid-tight connection between the water inlet pipe and the inner chambers of a multi-chamber pressure vessel. Background technique [0002] Such multi-chamber tanks (generally comprising two chambers separated by an at least partially flexible non-metallic membrane) are very common in the field of water storage for holding eg drinking well water, said multi-chamber tanks. Such multi-compartment containers, used primarily to hold aqueous liquids, typically include a metallic (eg, steel or aluminum) outer container and a non-metallic inner water-holding container. Maintaining a liquid-tight and gas-tight separation between these two volumes has been difficult. This difficulty and long-term problem involves connecting the metal water inlet pipe to the non-metallic inner vessel wall with a durable air-tight and liquid-tight seal that also forms a tight seal agains...
