CONTROLLED VALVE FOR FLUSH TANK FILLING Russian patent published in 2013 - IPC E03D1/32 F16B7/14 

FIELD: construction.

SUBSTANCE: valve comprises the main pipe for water supply, which may be fixed near the bottom of the appropriate flush tank. The main pipe is made as capable of adjustment of its length for adjustment to flush tanks of various depth. Near the upper part there is a neck for placement of various facilities for sending of a water flow, its closing and control. The water supply pipe comprises three main parts. All three parts are connected with each other as capable of mutual replacement in axial direction. One of the main parts forms an inner tube with a stem designed for fixation near the bottom of the flush tank. The inner tube enters the middle tube. The middle tube forms the second main part. The second part is installed inside the third main part as capable of limited displacement between both parts. The third main part may be considered as an outer one and has a facility for pulling and (or) pushing. This facility serves to perform the appropriate relative displacement of the middle pipe in the inner tube. Thus adjustment is realised along pipe height or length.

EFFECT: possibility to do manual control along height of an already installed drain valve.
