FIELD: sanitary engineering. SUBSTANCE: water discharge outlet includes discharge opening in the bottom of the sink and discharge pipe connected to syphon. The pipe is provided with a flange and seal ring on the side of the sink. The seal ring is imposed on bottom bead that is the contour of the discharge opening. As this takes place the discharge opening is made in the form of a sink-hole with grate on outlet opening being integrated into the sink bottom. A port for a screw is provided in the center of the grate. The pipe flange is provided with a ring groove on upper side, elastic seal ring is placed into the groove. A nut secured from radial trusts is provided inside flow passage. The flange with seal ring is installed on the constricting bead of the sink-hole from bottom outside, and the pipe is attracted to the bottom by a screw installed in the central port of the grate and screwed in the nut in pipe flow passage. EFFECT: simple and reliable device for water discharge from a sink. |
