Abstract
A vortex chamber valve for controlling fluid flow in a pipe system comprising a housing forming a vortex chamber having a curved sidewall, an inlet opening, and an outlet opening; an inlet valve disposed at an upstream side of the vortex chamber inlet opening having a main section and an edge section, wherein the edge section has a deflecting surface protruding away from the main section and towards the upstream side of the inlet valve, the edge section of the inlet valve covers a part of the inlet opening, so that, when upstream fluid levels rise at least up to the deflecting surface, the deflecting surface acts on the inflowing fluid to cause contraction in the inlet opening of the cross-sectional area of the inflowing fluid.
Claims14
A vortex chamber valve for controlling fluid flow in a pipe system, comprising:
- a housing forming a vortex chamber having a curved side wall, an inlet opening and an outlet opening;
- an inlet valve at an upstream side of the vortex chamber inlet opening having a main section and an edge section, said edge section having a deflecting surface protruding away from the main section and towards the upstream side of the inlet valve, said section of the inlet valve covering in an operative valve position a part of said inlet opening, so that, if upstream fluid levels rise at least up to the deflecting surface, said deflecting surface acts on inflowing fluid to cause contraction in said inlet opening of the cross-sectional area of the inflowing fluid.
A vortex chamber valve for controlling fluid flow in a pipe system, comprising,
- a housing forming a vortex chamber having a curved side wall, an inlet opening and an outlet opening,
- an overflow shaft including a dam wall and a bottom duct;
- said overflow shaft being positioned immediately upstream of the inlet opening, said duct extending from a dam wall to the inlet opening and being upwardly open at least in a duct portion near the inlet opening,
- an inlet valve disposed in or above said upwardly open duct portion, said inlet valve having a deflecting surface extending away from the inlet opening and downwardly.
A vortex chamber valve for controlling fluid flow in a pipe system, comprising,
- a housing forming a vortex chamber having a curved side wall, an inlet opening and an outlet opening;
- an inlet channel having a bottom leading to said inlet opening;
- and
- an inlet valve disposed at the upstream side of the vortex chamber inlet opening and having an edge section with a baffle surface protruding towards the upstream side of the inlet opening and towards the channel bottom;
- wherein said edge section acts on the inflowing fluid to contract in said inlet opening the cross-sectional area of the inflowing fluid when an upstream fluid level has risen at least up to said edge section.
