摘要： A removable automatic insertion device with segmented drainage shaft may be used to remove unwanted liquids from pipelines, tanks and other pressurized vessels. The insertion device inserts and withdraws the drainage shaft, one segment at a time into the pipeline or other pressurized vessel. A termination assembly is connected to the subsurface end of the drainage shaft and includes a normally closed drainage valve assembly. After insertion of the drainage shaft, the automatic insertion device is removed and a surface mounted discharge assembly is connected to the drainage shaft. To open the drainage valve assembly and commence drainage of unwanted liquids, pressurized fluid is injected through the discharge assembly, and a segmented hollow actuation tube to open the subsurface drainage valve assembly. Unwanted fluids then pass through the open drainage valve assembly, the drainage shaft to the surface mounted discharge assembly.

摘要： A sight glass with a flow directing assembly is used to detect the presence of entrained liquids in natural gas during spot sampling procedures. The flow directing assembly directs at least a portion of the gas flow to impinge upon a first transparent window and swirl around in a chamber of the sight glass which may cause droplets of liquid to form on the inside of the window and may cause a fog to form inside the chamber, all of which make it easier to see the existence of liquids in the natural gas. At least one embodiment of this sight glass also acts as a fluid separator, collecting the liquids in the chamber which may then be periodically drained.

摘要： A sampling cylinder for LNG (liquefied natural gas) is provided. The sampling cylinder includes a piston cylinder arrangement having opposite end members closing the chamber inside the cylinder. Various porting arrangements are provided for allowing fluid to be fed into a chamber inside the cylinder on opposite sides of a piston. A sample chamber is provided at one end member of the cylinder. The end member containing the sample chamber is also provided with a heat exchanger that may be connected to a source of coolant and preferably the LNG to be sampled to effect cooling of the end member at least partially prior to the sample chamber having a sample of LNG injected thereinto.

摘要： An integrated sampling device with liquid eliminator is provided. The device includes a body with integrated valving. A liquid eliminator device is provided within the body and interposed in a flow path such that gas will pass through and liquid will not. The gas will then be conducted to a sampling device while the liquid will pass through an exhaust port back to the source of fluid. An inlet valve is also provided to control the flow of fluid from the source to the liquid eliminator element. An outlet valve may be provided to control liquid back to the source.

摘要： A heated instrument regulator tip is shown for use in retrieving samples from the interior of a natural gas or similar pipeline. A well is disposed within the tip and adapted to receive an electrical heater. The heater supplements thermal fins on the tip to transfer thermal energy to the gas sample inside the tip. The thermal energy counteracts the Joule-Thompson cooling of the gas due to the rapid pressure drop, thus preventing freeze up or condensation within the regulator tip.

摘要： A fluid motor integrally constructed on an elongate body enables periodic fluid sampling. This device affixes to a pipeline by a threaded connection which positions an inlet in the pipeline for sample removal; the sample flows to a sample bite removal valve which is motor operated to obtain periodic simple bits. Pressure step up or down is achieved in a sample pressure isolation system having a check valve function. This enables storage at any pressure.

摘要： An apparatus is shown which prevents the intrusion of liquids into a gas chromatograph wherein a ball-check valve comprised of a flotation chamber and a spherical floatable valve element is positioned between and in fluid communication with an inlet and outlet port. While gasses are permitted to flow past the valve and into the gas chromatograph, liquids are retained within the flotation chamber by the floatable valve element. When the liquid level rises to a certain level within the chamber, the valve is closed by the pressure of the liquid forcing the floatable valve element into a closed and sealed position. The ball-check valve is also surrounded by a transparent member which allows the user to view the liquid level within the valve at all times.
