Abstract

Both buried pipelines and gated pipe are being used more frequently for
irrigation. Gated pipe has a number of advantages for delivering and controlling
irrigation water to furrows and corrugates. It is a convenient way of distributing
water to a field in an automated furrow irrigation system. To automate pipeline
systems, valves and controls must automatically sequence irrigation from one
turnout or irrigation set to another. Two types of pneumatic valves or closures
for controlling the discharge from buried pipeline systems have been developed
by Haise, et al. (2). Fischbach (1) extended the development and used a pneumatic
bladder or diaphragm inflated with air to automate a surface irrigation pipeline
valve. Haise and Payne (3) developed a self-closing valve which operates from
water pressure in the distribution pipeline. The Snake River low pressure irrigation
valves represent further modifications developed to control the discharge from
a field pipeline turnout into either gated pipe or directly into irrigation borders.
Three sizes of valves, 6 in. (150 mm), 8 in. (200 mm), and 10 in. (250 mm),
have been developed and tested for use in systems operating at pressures up
to about 12 psi (83 kN/m²). These are inflated with water from the pipeline
and close with water pressure from within the pipe.
