摘要： This disclosure relates to a system and method for generating a change in pressure proportional to fluid viscosity. In particular, the disclosure discusses a viscosity dependent pressure differential system. The system can comprise a first pilot stream, a second pilot stream, and a pressure sensing device that reads a differential pressure across a first junction on the first pilot stream and a second junction on the second pilot stream. The first junction is between a first section having a first predominant pressure loss characteristic, and a second section having a second predominant pressure loss characteristic. Similarly, the second junction can be between a third section having a third predominant pressure loss characteristic and a fourth section having a fourth pressure loss characteristic.

摘要： A vapor pressure equalization assembly having an underpressure relief assembly and an overpressure relief assembly in fluidic communication with the vapor space of a liquid storage tank (vessel). The underpressure and overpressure relief assemblies each have movable pistons sealingly engageable with respective sealing members, and biasing members which exert respective biasing forces to maintain the pistons in sealing engagement with the sealing members. A predetermined underpressure or overpressure differential between the vapor space pressure and atmospheric pressure will cause one of the pistons to open fluidic communication of the vapor space to equalize the vapor space pressure with that of the surrounding atmospheric pressure.

摘要： The present invention provides a method and apparatus for substantially eliminating destructive transients of pressure or flow rate which can degrade the efficiency and useful lifetime of chromatography columns. The present invention enables a substantially constant flow of mobile phase liquid to be maintained through the chromatography system by eliminating the flow blockage interval associated with the actuation of sample injection valves. The present invention further provides a method to reduce the pressure and flow rate transients associated with pressurization of the sample loop contents when the sample loop is introduced to chromatography system delivery pressure.

摘要： In a vinyl acetate manufacture reactor feed line, oxygen is admixed with gaseous hydrocarbons in the process stream by discharging the oxygen through jets facing downstream within the hydrocarbon gas flow, with the oxygen jet velocity maintained substantially higher than the velocity of the hydrocarbon gas. Variations in oxygen mass flow are made by varying the area of the jet orifices while maintaining a predetermined pressure drop across the same. The pressure within the oxygen feed line is controlled to control the pressure drop across the orifices with the oxygen flow rate in turn varying with variations in the orifice size.

摘要： A control valve for an air cushion bed includes a first main body, a membrane plate, a second main body, a sensor, and a depressurization unit. The membrane plate is clamped between the first main body and the second main body. The second main body at one side of the membrane plate is connected with the sensor. The sensor is used to detect the inputted air pressure. When the air is over, the air can be depressurized by the depressurization unit. The control valve of the present invention is applied to input and control the air of the air cushion bed, having depressurization and air detection functions.

摘要： Apparatus for equalizing pressure within a vapor space of a storage vessel. In accordance with various embodiments, a pressure equalization assembly has a base housing member adapted to be mounted to a tank adjacent a tank aperture in fluidic communication with a vapor space of the tank. A canister assembly is adapted for removable engagement with the housing member between a closed position and an open position. The closed position establishes a fluidic seal interface between the housing member and the canister assembly. The open position provides user access to the vapor space through the tank aperture. The canister assembly further has a compound seal assembly with first and second pistons biased against corresponding first and second annular seal members while the canister assembly is in both the closed position and the open position. A third annular seal member is disposed between the canister assembly and the base housing member.
