With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers. For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...
A ceramic valve is a valve with ceramic trim, ball, seat, disc or lining. A carbon steel or stainless steel body is used to protect the ceramic trim from being damaged by sudden thermal or mechanical shock. Advanced ceramics are used in the manufacture including alumina, [1] zirconia and silicon nitride.
A .32 ACP FMJ cartridge, a .32 ACP FMJ cartridge in a blued .303 British supplemental chamber, and a .303 British FMJ cartridge (left to right) A caliber conversion device is a device which can be used to non-permanently alter a firearm to allow it to fire a different cartridge than the one it was originally designed to fire.
Turning a valve knob or lever adjusts flow by varying the aperture of the control device in the valve assembly. The result when opened in any degree is a choked flow . Its rate is independent of the viscosity or temperature of the fluid or gas in the pipe, and depends only weakly on the supply pressure , so that flow rate is stable at a given ...
A rupture disc (burst) Pressure-effect acting at a rupture disc A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
Caseless ammunition (CL), [1] or caseless cartridge, is a configuration of weapon-cartridge that eliminates the cartridge case that typically holds the primer, propellant and projectile together as a unit. Instead, the propellant and primer are fitted to the projectile in another way so that a cartridge case is not needed, for example inside or ...
Pierceable gas cylinder Gas cylinder with Lindal B188 valve.. EN 417 is a European Standard concerning non-refillable metallic cartridges for liquefied petroleum gases.The standard specifies material, construction, inspection and marking requirements for cartridges with or without a valve, for use with portable appliances which comply with the requirements of EN 521.
Globe valve. A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. [1] Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.
