SANITARY ENGINEERING SIPHON DRAIN Russian patent published in 2000 - IPC

FIELD: sanitary engineering, applicable for sewage disposal to sewage conduit from wash-stands, wash-basins, washers, etc. SUBSTANCE: siphon drain has a body with an upper inlet and side outlet and a curvilinear guide lower part, exhaust in the inlet, grate with a central hole for placement of the fastening wood, screw-cutter, as well as a water derivation linked with the outlet. The interior of the siphon drain body made in the form of a cylinder is divided into the flow and drain parts by means of a vertical partition, whose lower end is positioned at the level of the horizontal plane passing through the beginning of the curvilinear guide lower part. The upper end of the partition, located in the immediate closeness to the inlet, is inclined at an obtuse angle over the convex part of the body interior, and at the same time with its lower surface forms the above exhaust together with the inner surface of the inlet facing it; the hole for placement of the fastening wood screw-cutter is made in the center of the top of the partition vertical part. A taper-cylindrical bulge is made around the hole for the wood screw-cutter in the central upper part of the partition. The water drain is made integral with the body on the outlet and represents a branch pipe with an annular stop on the outer surface, and several spiral bosses located behind it in the direction of water flow and intended for screwing-on of the flexible spiral water drain hose. EFFECT: simplified design and reduced quantity of assembly units, reduced leakages and simplified manufacture and mounting. 3 cl, 2 dwg
