What is a slide gate?
What is a slide gate?
Unlike common knife gates, a slide gate is a component that fits into a system specifically engineered to handle dry bulk powders, pellets, and granules. Slide gate valves are linear motion valves in which a flat plate slides into the flow stream to provide a shut-off of material or air.
What are slide gates used for?
A common application for Slide Gates is on an intake structure. A Slide Gate may also be used as a Weir Gate that lowers to open. The water passes over the top making this style useful for passing floating debris. Dual stem arrangements can be provided for extra wide gates.
Where is sluice gate used?
A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway. Sluice gates commonly control water levels and flow rates in rivers and canals. They are also used in wastewater treatment plants and to recover minerals in mining operations, and in watermills.
What is automatic sluice gate?
Sluices are built at river confluences where tributaries flow into the main stream. The DL8 Series Web Data Loggers provide a systematic solution for monitoring and recording of river water levels, and for opening/closing water gates automatically if an abnormality is detected.
What is the difference between a gate valve and a knife gate valve?
The biggest difference between these two types of valves is that gate valves are built to ANSI standards while knife gate valves adhere to TAPPI standards. A gate valve will have a v-ring packing set that seals the shaft attached to the gate, while a knife gate valve has a packing gland that seals around the gate.
What is a cantilever sliding gate?
A cantilever sliding gate rests and rolls on a wheel on the front bottom edge of the gate with a track supporting wheels on the back edge. In contrast, a cantilever gate is held above the ground, moving via rollers running along the top and inside of the fence with wheels attached to a vertical concrete foundation.
What is sluice gate and what are the uses of sluice gate?
What is a sluice gate? 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.
Why do dams have sluice gates?
A sluice gate regulates how and where water is moved. A sluice gate is a mechanism used to control water flow. These devices are often used in water treatment plants, mining, dams, rice fields, and cranberry bogs, among other places. A sluice gate may be used in rice fields to control flooding or water levels.
What is the difference between sluice and weir?
Weirs are commonly used to control the flow rates of rivers during periods of high discharge. Sluice gates (or in some cases the height of the weir crest) can be altered to increase or decrease the volume of water flowing downstream.
How does a sluice work?
Sluice boxes work by essentially creating a straight, consistent channel, with regularly spaced slow spots created by riffles. Each riffle creates an eddy, a backflow of water that allows the gold to settle out. Material is placed at the top of the box and carried in suspension down the channel.
What is sluice way?
Sluiceway meaning An artificial channel for water, with or without a floodgate; sluice. noun. An artificial channel, especially one for carrying off a portion of the current of a stream, canal, or other larger body of water. A man-made channel designed to redirect excess water.
Why do we use sluice gate?
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 the difference between a knife gate and a slide gate?
As often as the two terms are intermingled, a knife gate and a slide gate are NOT the same. A knife gate valve is a component that utilizes a blade to cut through clogging of heavy liquids; whereas a slide gate valve is a component utilizing a slide plate in order to better manipulate or control the flow of dry bulk material.
What are slide gate valves?
Slide gate valves are linear motion valves in which a flat plate slides into the flow stream to provide a shut-off of material or air. The gate can close or open the slide plate on a moving column of material at all times.
What are the different types of sluice gates?
Pressure-type small sluice gates such as buckets and agricultural gates are often pressure-free. The culvert inlet gate is composed of three parts: the entrance header, the tunnel body, and the entrance and exit connecting section.
What is the function of gate valve?
Gate valves are used to permit or prevent the flow of liquids, and are typically for on/off control rather than flow regulation.Gate valve is difference from ball valve and butterfly valve. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.
