Abstract: The rapid assembly flange joint consists of a connecting device in the form of a constricting collar made up of at least two parts with a shaped groove on the concave face, the groove corresponding to the cross-section of the two coupled flanges of the members that are being connected, and clamping elements in the form of retaining sections on the flanges. The connecting device is provided with fasteners in the form of walls; the retaining sections are in the form of grooves, the width of which is not less than the thickness of the one or two fasteners that engage therewith. The number of grooves is not less than the number of component parts of the connecting device. The rapid assembly flange joint provides for a reliable connection between flanged cylindrical members without the need for additional fastening and clamping elements and without increasing the sizes of the connection point.

Abstract: The inventions relate to purifying water and can be used in domestic water purification systems. The claimed filtered water storage unit for the storage device of a water purification system includes a housing, an elastic chamber for filtered water, and a region for pressurizing untreated water. The water purification system includes a reverse osmosis membrane, a clean water discharge pipe, an overflow into a drain, a clean water tap, and a storage device having a filtered water storage unit and a hydroautomatic unit. The outlet of the controlled chamber of a valve is associated with the water pressurizing region in the housing of the water storage unit, and the input of the controlling chamber of a valve is associated with the clean water discharge pipe upstream of the tap, wherein the valve for controlling water pressurization is normally open and the valve for controlling drainage is normally closed.

Abstract: The invention relates to flange joint devices. The rapid assembly flange joint consists of a connecting device in the form of a constricting collar made up of at least two parts with a shaped groove on the concave face, said channel corresponding to the cross-section of the two coupled flanges of the members that are being connected, and clamping elements in the form of retaining sections on the flanges. The connecting device is provided with fasteners in the form of walls; the retaining sections are in the form of grooves, the width of which is not less than the thickness of the one or two fasteners that engage therewith. The number of grooves is not less than the number of component parts of the connecting device. The invention provides for a reliable connection between flanged cylindrical members without the need for additional fastening and clamping elements and without increasing the sizes of the connection point.

Abstract: The inventions relate to means for purifying water, primarily drinking water, and can be used in domestic water purification systems. The claimed filtered water storage unit for the storage device of a water purification system comprises a housing, an elastic chamber disposed therein for filtered water, and a region for pressurizing untreated water, which is defined between the wall of the chamber and the wall of the housing. The elastic chamber is made of a modified biaxially oriented thermoplastic elastomer and consists of a chamber body and neck, formed as a single piece, the neck being rigidly secured in the housing. The water purification system comprises a reverse osmosis membrane, a clean water discharge pipe, an overflow into a drain, a clean water tap, and a storage device comprising a filtered water storage unit and a hydro-automatic unit.
