Irrigation valve

摘要

An irrigation valve has a liquid passage, a sealing diaphragm and a control port that can receive control signals. The sealing diaphragm is held in the valve in a non clamped manner and is adapted to seal the passage. Upon receipt of a control signal the sealing diaphragm bends and opens a path for liquid around the sealing diaphragm that can exit the valve.

1. An irrigation valve comprising:
a liquid passage extending therethrough at least in part along an axis, a sealing diaphragm operatively coupled to the passage, and a control port for receiving a control signal, the control port not being in fluid communication with the liquid passage, the sealing diaphragm being held in the valve in a non clamped manner and being adapted to seal the passage, wherein upon receipt of a control signal the sealing diaphragm is urged to elastically bend to thereby open a path for liquid around the sealing diaphragm that flows downstream to exit the valve.
