摘要： A variable pressure reducing device for reducing high pressure in steam and hot water samples forces the liquid through an annular passageway between a pair of rods within a complementary pair of tubes. The flow rate through the rod-in-tube device, or the pressure drop across the device, is adjustable by means of a rotatable guide screw for adjusting the position of the rods within the tubes. The rods are tapered to provide a smooth flow of liquid through the device. The seal around the guide screw is self energized by means of a seal jacket between a valve gland and a stem portion of the guide screw constructed so that the biasing force of a spring on the seal jacket is supplemented by pressure from liquid flowing through the device The guide screw is centered within the valve gland to keep the guide screw properly aligned, particularly when the device is used with a motor for rotating the guide screw to adjust the position of the rods.

摘要： An automated sample conditioning system for conditioning and preparing steam and hot water samples at a constant flow rate and velocity continuously monitors and adjusts flow rate in the sample line. Sample flow is metered through a flow rate device such as an orifice plate of known flow characteristics, and a downstream pressure value is provided by either a fixed back pressure regulator/relief valve or by a pipe section of known length and diameter. A pressure transducer continuously monitors pressure in the sample line upstream from the orifice plate. A control analyzer automatically adjusts a motorized pressure reducing device in response to fluctuations in pressure monitored by the pressure transducer in order to maintain constant flow rate and velocity. Monitoring devices and displays acquire, display and control critical pressure, temperature and flow rate parameters throughout the system. Network communications capability for remote, unattended monitoring control and data acquisition is also provided.

摘要： The pressure reducing element includes an elongated body having an axially-extending, cylindrical bore including three stepped portions of increasing diameter. Pressure is regulated by a stepped cylindrical valve rod having an outer end located exteriorly of the body and a pressure regulating portion normally located inside the bore and including two pressuring regulation sections of increasing diameter. The valve rod is moved axially within the bore to adjust the outlet pressure by rotating a handle on the outer end of a spindle which is connected to the valve rod and threaded into a collar carried by a fixture mounted on the body for relative axial movement. The valve rod is urged toward an adjusted position by a compression spring encircling the exterior of the body with one end restrained against axial movement relative to the body and the other end bearing against a spring retainer carried by the fixture. If the element becomes plugged with foreign particles, the valve rod can be retracted, while in any adjusted position, by pulling on the handle which causes the spring to compress and permit sufficient travel of the valve rod to move the larger pressure regulating section into the next larger bore portion, thereby facilitating flushing of the particles from the element by system pressure.
摘要翻译： 减压元件包括具有轴向延伸的圆柱形孔的细长主体，其包括增加直径的三个阶梯部分。 压力由具有位于主体外部的外端的阶梯式圆柱形阀杆和通常位于孔内部的压力调节部分调节，并且包括两个增加直径的压力调节部分。 阀杆在孔内轴向移动以通过旋转主轴的外端上的手柄来调节出口压力，所述手柄连接到阀杆并拧入由安装在主体上的夹具承载的轴环以进行相对的轴向运动。 阀杆通过围绕主体外部的压缩弹簧被推向调节位置，其一端相对于主体被限制抵抗轴向移动，而另一端支承固定装置承载的弹簧保持器。 如果元件被外来颗粒堵塞，那么阀杆可以在任何调节位置通过拉动把手而拉动，导致弹簧压缩并且允许阀杆的足够行程将较大压力调节部分移动到 下一个较大的孔部分，从而便于通过系统压力从颗粒中冲洗颗粒。

摘要： A device for separating gas from a liquid sample stream including a housing defining a vertical, cylindrical chamber, a tangential fluid inlet for introducing a sample stream into the top portion of the chamber, a tangential outlet through which the liquid portion of the sample flows from the bottom of the chamber, a tubular-like gas separator unit in the top of the chamber, a gas outlet opening to the upper end of the gas separator unit, and a capillary tube connected to the gas outlet. The gas separator unit includes a spirally extending wall spaced radially inwardly from the top of the chamber wall to define an annular passage open to the fluid inlet. The side edges of the spiral wall are arranged to define a vertically extending opening therebetween. The sample stream entering through the inlet under pressure initially flows circumferentially through the annular passage, the heavier liquid portion tends to follow the chamber wall, and a substantial portion of the gas bubbles in the sample is separated therefrom and "scooped" into the gas separator unit through the vertical opening. The gas separated from the sample and collecting inside the gas separation unit flows through the capillary tube which restricts flow so as to minimize the overflow of liquid.
