Contamination-resistant valve for high-temperature, high-pressure applications

摘要: The valve for use in thermal shock deburring apparatus, which oxygen and hydrogen are combined under explosive conditions, provides reliable shut-off of the respective gas component being supplied to an explosion jet chamber, prevents backfire or backflash, is enclosed a housing formed with bore, preferably cylindrical, insert sleeve located; resiliently deformable sealing material such as, example, Teflon, located between portion bore sleeve. A plunger shaped engage seat thereagainst; projecting cylindrical fitting into so that, upon engagement substance, inwardly directed radial pressure will additionally be exerted deformation substance over against projection, provide seal and, if contamination should damage material, resilient permits self-healing thereof.
