Milk tube dome with flow controller
A milker unit liner dome having an inner surface and flow diverters joined to the inner surface to redirect teat dip from an inlet to provide more uniform coverage of dip on a teat. The liner dome can also include more than one flow diverter for redirecting teat dip flow.
1. A milker unit liner comprising:
a barrel; and
a dome joined to the barrel, and the dome comprises:
an upper inner surface defining a teat opening;
a flow diverter joined to the upper inner surface of the dome, and the flow diverter includes a ridge extending generally downward and away from the upper inner surface to at least partially define an open teat dip flow path along the upper inner surface of the dome while the milker unit liner is generally upright and attached to a dairy animal teat, and the open teat dip flow path at least partially surrounds the teat opening to direct teat dip to a teat extending through the teat opening; and
a teat dip inlet to the dome disposed adjacent to and below the flow diverter to direct teat dip flow into contact with the flow diverter.
2. The milker unit liner dome of claim 1 , wherein the flow diverter has an end adjacent to the teat dip inlet and an end that is spaced apart from the teat dip inlet.
3. The milker unit liner dome of claim 1 , wherein the flow diverter includes an arcuate flow contact surface.
4. The milker unit liner dome of claim 1 , wherein the teat dip inlet is a slot.
5. The milker unit liner dome of claim 1 , wherein the teat dip inlet comprises a one-way valve.
6. The milker unit liner dome of claim 1 , and further comprising a second flow diverter including a ridge joined to the upper inner surface of the dome and the second flow diverter at least partially defines the open teat dip flow path along the upper inner surface of the dome.
7. The milker unit liner of claim 1 , wherein the flow diverter is shaped to redirect teat dip flow from a substantially upward and longitudinal direction relative into the barrel to a flow pattern against the upper inner surface of the dome.
8. A milker unit liner comprising:
a barrel; and
a dome joined to the barrel, and the dome comprises:
an upper inner surface defining a teat opening;
a flow diverter joined to the upper inner surface of the dome, and the flow diverter includes a ridge extending generally downward and away from the upper inner surface to at least partially define an open teat dip flow path along the upper inner surface of the dome while the milker unit liner is generally upright and attached to a dairy animal teat, and the open teat dip flow path at least partially surrounds the teat opening to direct teat dip to a teat extending through the teat opening; and
a teat dip inlet to the dome, wherein the flow diverter is disposed adjacent to and above the inlet to receive and direct teat dip from the inlet.
9. The milker unit liner dome of claim 8 , wherein the flow diverter has an end adjacent to the teat dip inlet and an end that is spaced apart from the teat dip inlet.
10. The milker unit liner dome of claim 8 , wherein the flow diverter includes an arcuate flow contact surface.
11. The milker unit liner dome of claim 8 , wherein the teat dip inlet is a slot.
12. The milker unit liner dome of claim 8 , wherein the teat dip inlet comprises a one-way valve.
13. The milker unit liner dome of claim 8 , and further comprising a second flow diverter including a ridge joined to the upper inner surface of the dome and the second flow diverter at least partially defines the open teat dip flow path along the upper inner surface of the dome.
14. The milker unit liner of claim 8 , wherein the flow diverter is shaped to redirect teat dip flow from a substantially upward and longitudinal direction relative into the barrel to a flow pattern against the upper inner surface of the dome.
