摘要：本発明の蒸気トラップ（１）は、円筒形の側壁を有する室（８）と、側壁の上部端に向かって設けられた入口２０と、その基部に設けられた逃し孔（１６）とを備える。入口（２０）は、室（８）内での流体の回転流を促進するべく流体を室（８）内に導き、逃し孔（１６）の上流に低圧区域を生成して孔（１６）の排出速度を制限する。即ち、冷たい水は急速に排出し、流体が飽和温度に近づきフラッシュ蒸気が発生すると排出速度を急速に減少させる。

摘要： A float operated device such as a pressure powered pump has a chamber 8 in which a float 10 is supported by a lever 12 for pivotable movement. The float 10 operates a toggle mechanism 28 by way of an arm 18 and extension 20 rigidly connected to the lever. Lever 12 also connected by a pivotably operating rod 48 to a valve element 44 controlling flow through a condensate outlet 38. The toggle mechanism 28 and the float 10 are supported by a cover 6, which is also provided with motive fluid inlet and outlet ports 32, 34, a condensate inlet 36 and the condensate outlet 38. The chamber 8 is defined by the cover 6 and a bowl portion 4 which is removable to allow servicing of the moving parts. The toggle mechanism operates to open/close the motive fluid inlet port 32. The motive fluid is preferably steam.

摘要： There is disclosed a method of determining the phase compositions of a multiphase fluid flow in a fluid line, including obtaining a vibration signal from the fluid flow using a vibration sensor comprising a target disposed in the fluid flow which vibrates in response to fluid flow in the fluid line. The vibration signal is analysed to determine a first energy parameter which is related to the energy of the vibration signal within a first frequency band, and a second energy parameter which is related to the energy of the vibration signal within a second frequency band; and a phase composition parameter, such as a dryness parameter, relating to the phase compositions of the fluid flow is determined using the first and second energy parameters. There is also disclosed an apparatus for determining the phase compositions of a multiphase fluid flow in a fluid line.

摘要： A differential pressure metering apparatus includes a manifold for fluidically coupling impulse lines. The manifold also includes a rigid body having a base, and an arm extending from the base, with a high and low pressure channel extending through the body from a high pressure inlet to opposing first and second high pressure outlet ports, and from a low pressure inlet to opposing first and second low pressure outlet ports respectively. The manifold is configured to be mounted to a flow restrictor pipe section in a wet-line configuration, in which the first high and low pressure outlet ports define impulse line extension directions having a downward component, and the second high and low pressure outlet ports define impulse line extension directions having an upward component.
