Headgate meaning Primary gate or valve at aqueduct or other source that can be opened or closed to regulate the flow of water entering an irrigation system (of lesser gated canals and irrigation ditches). noun. A moveable framework designed to hold still the heads of cattle for various procedures.
What is turnout in irrigation canal?
Turnout Functions On/off control of water flow. 2. Flow rate control. That is, a turnout usually has a valve to adjust the flow rate somewhere between maximum and zero. However, in many cases the downstream conditions determine the flow rate, and the turnout on/off control valve remains completely open.Dec 15, 2010
What are slide gates?
Slide Gates. KWS Slide Gates are used to control the discharge of bulk materials from hoppers, bins, silos or conveyors. A slide gate consists of a rigid frame with a slide plate located inside the frame that opens and closes against the flow of the bulk material.
What is the difference between a slide gate and a sluice gate?
Sluice gates only seal on one side, typically a cast iron gate with brass "wedges" that force the face of the gate against the frame where a brass face on the frame and gate seal against eachother. On a slide gate typically made of stainless steel, a flat plate "gate" slides inside two channels in the frame.Mar 1, 2005
What is a weir gate?
Weir Gates are designed to control upstream water elevation and can provide a rough estimate of flow using notched gates via the downward- opening design. Weir gates function like slide gates, except that the disc opens downward allowing outflow to weir over the top of the gate.
What is the purpose of a sluice valve?
The gate that controls a sluice is a valve known as a “sluice gate.” These valves are designed to seal in one direction and commonly are used to control water levels and flow rates in rivers and canals. They also are used in wastewater treatment plants.
What is sluice gate valve?
A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.
What is the difference between a gate valve and a sluice valve?
Sluice Valve and/or Gate Valve functions strictly to either start or stop the flow. Gate valves are used for water supply systemwater supply systemA water distribution system is a part of water supply network with components that carry potable water from a centralized treatment plant or wells to consumers to satisfy residential, commercial, industrial and fire fighting requirements.https://en.wikipedia.org › wiki › Water_distribution_systemWater distribution system - Wikipedia and sluice valves are used for slurries. ... Mainly two types of spindles (wheel to turn valve on and off, at top of the stem) are used for raising the gate of sluice valve.Apr 10, 2018
What is an irrigation gate valve?
A gate valve is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. ... Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose.
What's the purpose of a gate valve?
Gate valves are used when a straight-line flow of fluid and minimum flow restriction are needed. Gate valves use a sliding plate within the valve body to stop, limit, or permit full flow of fluids through the valve. The gate is usually wedge-shaped.
Which is better a ball valve or a gate valve?
Ball valves are more effective at forming a tight seal and have more reliability and longevity than gate valves, but tend to be more expensive. They are often used for shutoff and control applications. Because ball valves can open and close immediately, they are more likely than gate valves to cause water hammer.
