Abstract
A vent valve for steam radiators fired by intermittent furnaces is disclosed. The valve includes a conduit with two portions. Two blocking rods form constricted areas within the two portions to throttle air escaping from the radiator.
Claims14
A vent valve for use with a radiator comprising:
- a conduit adapted to be placed in fluid communication with a radiator, said conduit having a first portion, a second portion extending transversely therefrom, an upper outlet port in fluid communication with said second portion, and a hollow interior extending through said portions of said conduit;
- a first blocking rod supported within said first portion, said first blocking rod having at least one opening to provide a vent passage into said hollow interior of said conduit, first means for condensing water from the air venting from the radiator comprising said first rod and said first portion forming a first constricted area between the exterior of said first rod and the interior surface of said first portion;
- and
- a second blocking rod mounted adjacent to said upper outlet port and extending into the hollow interior of said second portion, second means for condensing water from the air venting from the radiator comprising said second rod and said second portion forming a second constructed area between the exterior of said second rod and the interior surface of said second portion.

A vent valve for use with a radiator comprising:
- a conduit adapted to be placed in fluid communication with a radiator, said conduit having a first portion, a second portion extending transversely therefrom, an upper outlet port in fluid communication with said second portion, and a hollow interior extending through said portions of said conduit;
- said second portion having a threaded exterior and an upper edge,
- a screw supported within said hollow interior of said first portion, screw having a head with at least one opening to provide a first vent passage into said hollow interior of said conduit, said first vent passage forming first means for condensing water from the air venting from the radiator;
- a cap having a threaded interior surface mating with the threaded exterior of said second portion and an upper interior surface with a hole formed therethrough, said cap being threaded down onto said second portion;
- a nut supported on said upper edge of said second portion of said conduit within and beneath said cap and secured thereto by contact with said upper interior surface of said cap;
- a bolt having a head facing outward, located above said cap, and a threaded shank extending inward through said cap hole, said shank being threaded into a threaded hole of said nut and extending into the hollow interior of said second portion of said conduit;
- a washer located between said cap and said bolt head, said bolt shank passing through said washer;
- and
- said bolt shank being tapered on at least one side to provide a second vent passage from said hollow interior of said conduit between said tapered side and the threaded hole of said nut, said second vent passage forming second means for condensing water from the air venting from the radiator.

- a first screw supported within said hollow interior of said first portion, said screw having a head with at least one opening to provide a vent passage into said hollow interior of said conduit;
- a washer supported on said upper edge of said second portion of said conduit;
- a second screw having a slotted head and a shank, said second screw shank extending through a hole in said washer into said hollow interior of said second conduit so that said second screw is supported by its head resting on top of said washer and a vest passage is formed between said head of said second screw and hole in said washer;
- and
- a cap having a threaded interior surface mating with the threaded exterior of said second portion and an upper interior surface with a hole formed therethrough, said cap being adjustably threaded down onto said second portion whereby the upward and downward adjustment of said cap and said second portion adjusts the degree which said washer and second screw can be moved upwardly by the pressure of the venting air;
