Valves A valve is a device that regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically pipe fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. Valves are used in a variety of contexts, including industrial, military, commercial, residential, and transport. There are many types of valves such as gate valve, glove valve, angle valve, automatic stop valve, cheek valve, back pressure valve, butterfly valve, diaphragm valve etc. Valve materials: Ø   For larger size cast iron or cast steel or forged steel is used. Ø   For valves seats, discs and spindles brass is used. 1.       Gate valve, Glove valve, Angle valve, Automatic stop valve etc are called normally stop valve because they are used to stop the flow of fluids. ...

Turbine: A turbine is a rotary engine that extracts energy from a fluid flow and converts it into useful work. The simplest turbines have one moving part, a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades, or the blades react to the flow, so that they move and impart rotational energy to the rotor. Types of turbine: 1.       Steam turbine 2.       Gas turbine 3.       Water turbine 4.       Wind turbine 5.       Transonic turbine 6.       Ceramic turbine Steam turbine: Steam turbine is such type of turbine where steam is used as working fluid. When steam is injected over the blades it rotates at a certain speed. Since steam is used for rotation it is called steam turbine. Generally it is used at steam turbine power station. In Ashuganj power station, steam tur...
