US 9,945,112 B2 · Valve for use in a sewage line

Abstract

In a first embodiment, the present invention is a valve insertable into a sewage line in order to prevent backflow into a structure. The valve includes a mouth formed therein which corresponds to the size of an inlet of the sewage line and means for rotating for rotating the valve within the sewage line. Rotation of the valve to an open position aligns the mouth with the inlet of the sewage line to permit flow through the sewage line and rotation of the valve body to a closed position rotates the mouth away from the inlet of the sewage line to prevent flow through the sewage line. In a second embodiment, the present invention further includes a conduit adapter that replaces a converging section of the sewage line in order to retrofit the valve into a sewage line where the valve would otherwise not fit therein. Additionally, in either the first or second embodiment, the present invention provides for the simultaneous purging of the sewage line by attaching means for purging to the valve.

Dependent claims

A sewage line valve, comprising:

(a) a rotatable valve body insertable into a clean out port of a sewage line, the valve body including a cylindrical wall having an at least substantially closed first end and an open second end, the wall defining an open interior within the valve body;
(b) a mouth formed in the wall of the valve body providing an opening into the interior of the valve body, the mouth corresponding to the size of an inlet of the sewage line;
the mouth having and edge, the edge terminating at a sharpened lip for cutting waste flowing therepast;
(c) means for rotating the valve body between an open and a closed position;
and
wherein the mouth of the valve body aligns with an inlet of the sewage line when in the open position and, when in the closed position, the mouth of the valve body does not align with the inlet of the sewage line.

A sewage line valve assembly, comprising:

(a) a valve including:
(1) a rotatable valve body including a cylindrical wall having an at least substantially closed first end and an open second end, the wall defining an open interior within the valve body;
(2) a mouth formed in the wall of the valve body providing an opening into the interior of the valve body the mouth corresponding to the size of an inlet of the sewage line;
the mouth having an edge, the edge terminating at a sharpened lip for cutting waste flowing therepast;
(b) a substantially Y-shaped conduit adapter for securing the valve to a sewage line, the conduit adapter including:
(1) a cylindrical adapter body having an open first end and an open second end, the second end being securable to an end of the sewage line, the adapter body defining an open interior, the adapter body including an inlet formed within the adapter body corresponding to the size of the mouth in the valve;
(2) an inlet adapter extending outwardly from the inlet formed in the adapter body, the inlet adapter being securable to an end of an inlet line of a structure;
(c) means for rotating the valve body between an open and a closed position;
and
wherein the valve is slidably insertable into the first end of the conduit adapter;
and
further wherein the mouth of the valve body aligns with the inlet of the conduit adapter when in the open position and, when in the closed position, the mouth of the valve body does not align with the inlet of the conduit adapter.
