摘要： This invention makes possible the use of a very small pressure relief valve for protecting pressure gauges, thermometers, humidity indicators and other detectors from excessive pressure in an element in which the fluid is contained and of which the indicators must measure a characteristic. The pressure relief valve is located in an exhaust branch outlet from passages that connect the detector with the element in which the fluid is contained; and the relief valve has a housing with an inlet port of a cross-section much less than the cross-section of the passage from the element containing the fluid. This inlet port throttles the flow of fluid into the relief valve. By thus reducing the cross section of the inlet port, the relief valve can be as small and inexpensive as desired, commensurate with the flow required by the detector where the detector is of a nature requiring a flow of the fluid.

摘要： An improved method and apparatus for regenerating desiccant in an adsorption dryer is disclosed. The method utilizes a two-phase regeneration, the first phase using the heat from the compressed gas supply to desorb a portion of the moisture from a regenerating desiccant chamber, with the second phase utilizing low pressure, dry product gas. The heat of compression/pressure swing combination offers reduced regeneration energy requirements with improved dewpoint performance.

摘要： Water contamination is purged from molecular sieve material used in oxygen concentrators by heating the molecular sieve material to a temperature in the range of approximately 450.degree. to 950.degree. F., and subjecting the molecular sieve material to a stream of dry sweep gas having a dew point in the range of approximately -80.degree. to -100.degree. F. In the preferred embodiment, the molecular sieve material is contained in a vessel and heated by means of a number of heating elements. In addition, a flow of dry sweep gas is produced by at least two drying chambers containing a desiccating material. A first valve assembly alternately cycles the sweep gas through the first drying chamber and then through said second drying chamber. A second valve assembly routes a portion of the sweep gas leaving the active drying chamber to the vessel, and routes the remainder of the sweep gas through the remaining drying chamber(s) to purge water from the desiccating material contained therein during the temporal portions of the cycle when each drying chamber is not supplying sweep gas to the vessel.
摘要翻译： 通过将分子筛材料加热至约450-950°F的温度，将分子筛材料从具有露点的干燥吹扫气体流中分离出来，从氧浓缩器中使用的分子筛材料中清除水污染物 点在约-80°-100°F的范围内。在优选的实施方式中，分子筛材料被包含在容器中并借助于多个加热元件加热。 此外，通过至少两个含有干燥材料的干燥室产生干吹气体流。 第一阀组件交替地将吹扫气体循环通过第一干燥室，然后通过所述第二干燥室。 第二阀组件将离开活性干燥室的吹扫气体的一部分引导到容器，并且将剩余的吹扫气体引导通过剩余的干燥室，以从其中包含的干燥材料中清除水， 每个干燥室不向容器提供吹扫气体的循环。

摘要： In some critical use, air-drying systems, 100% back-up capability is desired. The problem has been that an idle standby unit requires considerable time to reach full capability for dry air delivery. This invention bleeds enough dry air from the operating primary unit through parts of the idle back-up unit to maintain any dynamic conditions that are necessary to keep the standby unit ready for immediate use in the event of a failure of the primary unit.
