Abstract
A pipe cap includes a base, a cover, and an anchor assembly connecting the cover to the base. The base is connected to an open end of a vent pipe, and includes a sealing surface. The cover seals to the sealing surface and thereby seals the open end of the pipe so as to allow a build-up of pressure within the pipe. When the pressure exceeds a predetermined threshold value, the cover is blown off of the base to expose the sealing surface. The cover has a different visual appearance than the sealing surface. Thus, exposure of the sealing surface provides a visual indication of the occurrence of the pressure event.
Claims17
A cap for covering an open end of a vent pipe including:
- a base including a sealing surface, the base being configured to connect to the open end of the pipe;
- a cover configured to seal the open end of the pipe and to seal to the sealing surface so as to allow a build-up of pressure within the pipe, and to be blown off the sealing surface when the pressure exceeds a predetermined threshold value, the cover having a different visual appearance than the sealing surface;
- and
- an anchor assembly connecting the cover to the base before, during, and after the pressure event, and allowing the cover to be blown off of the sealing surface during the pressure event.
A method of monitoring for the occurrence of a pressure event inside a vent pipe, including:
- arranging a base, including a sealing surface, to an open end of the pipe;
- sealing a cover to the sealing surface, the cover sealing the open end of the pipe so as to allow a build-up of pressure within the pipe, the cover being configured to be blown off the sealing surface when the pressure exceeds a predetermined threshold value, the cover having a different visual appearance than the sealing surface;
- and
- connecting the cover to the base with an anchor assembly, the anchor assembly being configured to connect the cover to the base before, during, and after the pressure event, and allowing the cover to be blown off of the sealing surface during the pressure event.
