Abstract: A sewer relief valve assembly comprises a cylindrical sleeve dimensioned for insertion into a clean out which has an interior surface formed as a conduit and exterior threads adapted for mated engagement with the interior threads of the clean out. A valve means is disposed in the cylindrical sleeve which is displaceable from a closed position to an open position by pressurized fluid in the clean out. At least one perforated compartment is disposed inside the cylindrical sleeve which contains a water-soluble disinfectant composition. The valve means is displaceable by fluid pressure to the open position permitting discharge of the effluent through the clean out and the simultaneous release of the water-soluble disinfectant composition from the perforated compartment into the effluent. A water-soluble dye composition can also be included in the perforated compartment so that sewage overflow from the clean out is readily visible.

Abstract translation: 下水道安全阀组件包括圆柱形套筒，其尺寸适于插入清洁部分，其具有形成为导管的内表面和适于与清洁部分的内螺纹配合接合的外螺纹。 阀装置设置在圆筒形套筒中，其通过加压流体在清洁出口中从关闭位置移动到打开位置。 至少一个穿孔隔室设置在圆筒形套筒内部，其包含水溶性消毒剂组合物。 阀装置可以通过流体压力移动到打开位置，从而允许流出物通过清洁排出并将水溶性消毒剂组合物从多孔隔室同时释放到流出物中。 多孔隔室中也可以包含一种水溶性染料组合物，从而清洁出来的污水容易被看见。
