Abstract
Apparatuses manage the flow of fluids, such as, for example, water, through pipes. Specifically, the apparatuses of the present invention create a backward pressure in fluid traversing the pipe, wherein the backward pressure within the pipe provides compression of the fluid effectively compressing entrapped gas bubbles within the fluid, allowing more accurate water meter measurements. The apparatuses comprise spring seats for holding springs therein in alignment, and further comprise conically-tapered apertures for providing improved water flow through the apparatuses. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for managing fluids are further provided.
Claims11
An apparatus for managing the flow of fluid through a pipe comprising:
- a housing forming an internal chamber having an inlet opening and an outlet opening wherein pressurized fluid flows through the housing;
- a poppet valve mounted to a shaft and disposed within the internal chamber, the poppet valve configured to contact a seat in proximity to the inlet opening wherein the poppet valve contacting the seat prevents the flow of fluid through the housing and into the chamber from the inlet opening;
- a base plate spanning a cross-section of the housing in proximity to the outlet opening, the base plate having a central opening slidably receiving the shaft, an internal surface, and at least one aperture within the base plate for allowing the flow of fluid through the outlet opening,
- wherein the aperture has an inlet side into which the fluid flows and an outlet side out of which the fluid flows as the fluid flows therethrough, wherein the inlet side has a conical taper from the inlet side of the aperture to a midpoint between the inlet side and the outlet side wherein the size of the aperture at the inlet side is larger than the size of the aperture at the midpoint, and further wherein the outlet side has a conical taper from the midpoint to the outlet side of the aperture wherein the size of the aperture at the midpoint is smaller than the size of the aperture at the outlet side;
- and
- a spring around the shaft having a first end and a second end, the first end of the spring disposed within a first depression in the poppet valve and the second end of the spring disposed within a second depression in the internal surface of the base, wherein movement of the poppet valve toward the base causes a compression of the spring.
An apparatus for controlling the flow of fluid therethrough, the apparatus comprising:
- a housing forming an internal chamber having an inlet opening and an outlet opening wherein pressurized fluid flows through the housing;
- a poppet valve mounted to a shaft and disposed within the internal chamber, the poppet valve configured to contact a seat in proximity to the inlet opening wherein the poppet valve contacting the seat prevents the flow of fluid through the housing and into the chamber from the inlet opening;
- a base plate spanning a cross-section of the housing in proximity to the outlet opening, the base plate having a central opening slidably receiving the shaft, an internal surface, and at least one aperture within the base plate for allowing the flow of fluid through the outlet opening,
- wherein the at least one aperture has an inlet side into which fluid flows and an outlet side out of which fluid flows as fluid flows therethrough, wherein the inlet side has a conical taper from the inlet side of the aperture to a midpoint between the inlet side and the outlet side wherein the size of the aperture at the inlet side is larger than the size of the aperture at the midpoint, and further wherein the outlet side has a conical taper from the midpoint to the outlet side of the aperture wherein the size of the aperture at the midpoint is smaller than the size of the aperture at the outlet side;
- and
- a spring around the shaft having a first end and a second end, wherein movement of the poppet valve toward the base causes a compression of the spring.
