Abstract
A double-bell siphon for liquid flow control that improves upon existing bell siphons by the addition of an outer bell which helps the bell siphon to stop siphoning when the liquid level drops below the intended level. Optionally, a cup further enhances the ability for the siphon to stop properly.
Claims4
An automatic double-bell siphon, comprising:
- a. a standpipe installed in a floor of a liquid reservoir;
- b. an inner bell consisting of a single unitary conduit that abuts the floor of the liquid reservoir and surrounds said standpipe with an annular space between said inner bell and said standpipe and which has an opening at a top end for fluids to enter and one or more openings at a bottom end for fluids to enter, wherein said one or more openings pass through a wall of the bottom end;
- c. an outer bell closed at a top end and open at a bottom end which covers and surrounds said inner bell with an annular space between said outer bell and said inner bell and which provides a channel for fluids to flow from a surrounding liquid reservoir into said inner bell.
An automatic double-bell siphon, comprising:
- a. a standpipe installed in a floor of a liquid reservoir;
- b. a cup that abuts the floor of the liquid reservoir and surrounds said outer belt said standpipe with an annular space between said cup and said standpipe and which has one or more openings in a base of the cup to allow fluids from the liquid reservoir to enter the base of the cup;
- c. an inner bell consisting of a single unitary conduit that abuts the cup and surrounds said standpipe with an annular space between said inner bell and said standpipe and which has an opening at a top end for fluids to enter and one or more openings at a bottom end for fluids from below the cup to enter said inner bell;
- d. an outer bell closed at a top end and open at a bottom end which covers and surrounds said inner bell with an inner annular space between said outer bell and said inner bell and wherein said outer bell is surrounded by said cup with an outer annular space between said outer bell and said cup and wherein said outer annular space provides a channel for fluids to flow from said cup into said outer bell.
