A valve stem is a self-contained valve that opens to admit gas to a chamber (such as air to inflate a tire), [1] and is then automatically closed and kept sealed by the pressure in the chamber, or a spring, [2] [3] or both, to prevent the gas from escaping.
The upper part of the valve stem, within the rocker box, is lubricated by oil. If this oil travels unchecked along the valve stem, engine HC emissions will become excessive. To control this, an elastomeric seal is fitted over the top of the valve guide. These may wear or stiffen with age, so are usually replaced whenever valves are removed for ...
The importance of valve leakage depends on what the valve is controlling. For example, a dripping tap is less significant than a leak from a six-inch pipe carrying high-pressure radioactive steam. In the United States, the American National Standards Institute specifies six different leakage classes, with "leakage" defined in terms of the full ...
The Dunlop valve, (also called a Woods valve, an English valve or a Blitz valve [1]) is a type of pneumatic valve stem in use—mostly on inner tubes of bicycles—in many countries, including Japan, [2] Korea, India, Pakistan, Sri Lanka, most European countries, and a number of developing countries.
A water-based sealant can be injected into the tire also through the valve stem. This contains less harmful chemicals and no aerosol gas. The sealant can then be driven into the tire using an air compressor. A flat tire can be repaired by a patch or plug; [4] or the tire may repair itself. Self-sealing tires work on punctures up to a certain size.
The word poppet shares etymology with "puppet": it is from the Middle English popet ("youth" or "doll"), from Middle French poupette, which is a diminutive of poupée.The use of the word poppet to describe a valve comes from the same word applied to marionettes, which, like the poppet valve, move bodily in response to remote motion transmitted linearly.
Wearing out of a surface between a disk and its seat in a valve could cause a leak between ports (valve inlets or outlets). Wearing out of packing around a turning valve stem or rotating centrifugal pump shaft could develop into fluid outleakage into the environment. For some frequently operating centrifugal pumps, such leakage is so expected ...
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 ...
