A blast gate is a gate valve used to focus a dust collection system's vacuum pressure for maximum dust (or other material) extraction at the desired location. Blast gates are positioned near individual pieces of machinery and operate by being closed by default, blocking air flow.
Gate valves may have flanged ends drilled according to pipeline-compatible flange dimensional standards. Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber ...
Explosion vent after installation. An explosion vent or rupture panel [1] [2] is a safety device to protect equipment or buildings against excessive internal, explosion-incurred pressures, by means of pressure relief.
A blast valve is used to protect a shelter, such as a fallout shelter or bunker, from the effects of sudden outside air pressure changes. A nuclear weapon creates a shock wave, which may produce sudden pressure changes of more than an atmosphere (about 1 bar) even several kilometres from the detonation point.
When using a gate, one thing that is used in certain applications such as manufacturing, mining, and others is the gate valve. Fluids will run through the valve to help lubricate the moving parts of a machine, transmit power, close off openings to moving parts, and to assist evaporating the amount of heat coming through.
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is of Scots origin, and was inherited from the earlier technology of mill ponds and watermills , with penstocks diverting pond waters to drive the mills.
Blast dampers usually employ some type of blade held open with tension from a spring. The damper blades close automatically when pressure overcomes the resistance offered by the spring. Various models differ in the amount of blast protection (e.g. 1 bar/14.5 psi or lower amounts of protection) and whether they stay closed after the blast or ...
Stoplogs are typically used in structures where the removal, installation, and replacement of the logs is expected infrequently. When larger flows of water are passing through a stoplog gate, it can be difficult to remove or place individuals logs. Larger logs often require multiple people to position and lift the logs.
