SENTRY冷却器TLR系列介绍及选型
Sentry® TLR 取样冷却器/热交换器可冷却工艺流中的样品。它看似简单，但却是设计独特的小型管壳式热交换器。要冷却的样品流过冷却器的管侧，冷却液流过壳侧。然后将冷却的样品送至实验室进行分析或通过管道输送至在线工艺仪表，以连续监测电导率、pH 值或其他化学成分等特性。

特点
• 双缠绕螺旋线圈设计
• *大限度地减少冷却水需求
• 多种特殊合金可提高耐腐蚀性
• 保留的壳侧垫片可减少重新组装时间
• 成型壳体消除了顶部壳体法兰焊接接口
• 无需拆卸法兰螺栓即可安装安装支架
• 如果需要更高的耐腐蚀性，则可提供所有 316 SS 结构

The Sentry® TLR sample cooler/heat exchanger cools a sample from a process stream. It may seem simple, but it is a uniquely designed small tube and shell heat exchanger. The sample to be cooled flows through the tube side of the cooler, and the cooling fluid flows through the shell side. The cooled sample then is taken to a laboratory for analysis or piped to in-line process instrumentation for continuous monitoring of properties such as conductivity, pH or other chemical constituents.

FEATURES 
• Double-wound helical coil design 
• Minimizes cooling water needs 
• Wide variety of exotic alloys for corrosion resistance 
• Retained shellside gasket reduces reassembly time 
• Formed shell eliminates top shell flange weld interfaces 
• Mounting bracket can be installed without removing flange bolts 
• All 316 SS construction available where higher corrosive resistance is desired



SENTRY减压阀VREL系列介绍
现代发电厂的水和蒸汽样品的化学分析需要精确控制流量和压力。然而，高压减压需求可能会带来取样问题。Sentry VREL 控制阀由两根不锈钢管组成，连接到一个大管或桶上。锥形杆组件插入桶上的精密孔中。高压流体进入，流过一根杆，转动并流过另一根杆，然后流出。压降是插入桶中的杆的长度的函数。在层流条件下，压力平稳降低，通过不连续的压降将任何成分的解离降到*低。杆的位置通过转动旋钮从外部控制，可以在样品流动时进行调整。如果发生堵塞，可以缩回杆，这样系统压力就可以吹过固体物质。根据 ASTM 标准年鉴 ASTM 名称 D3370，Sentry VREL 控制阀是大于 500 psig（34.5 barg）样品的行业标准。

特点
• 符合人体工程学的调速手柄大大减少了转动力度
• 不会腐蚀阀门/调节器或拉丝
• 精细的流量控制
• 完全可伸缩杆确保轻松在线清洗
• 加长主体设计消除了弯管的可能性
• 流量从每分钟 150 毫升到每分钟 4 升，标准压降高达 5000 psig (345 barg)，超临界发电厂应用压降高达 7803 psig (538 bar)

Chemical analysis of water and steam samples in modern power generation plants requires precise control of flow and pressure. However, high-pressure reduction needs can present sampling problems. The Sentry VREL control valve consists of two stainless steel tubes joined to a large tube or barrel. A tapered rod assembly is inserted into precision holes in the barrel. The high pressure fluid enters, flows past one rod, turns and flows past the other rod, and then out. Pressure drop is a function of the length of the rods inserted into the barrel. The pressure is reduced smoothly under laminar flow conditions, minimizing dissociation of any components through discontinuous pressure drops. The rod position is controlled externally by turning the knob, and can be adjusted while sample is flowing. If blockage occurs, the rods can be retracted so system pressure can blow the solid matter through. The Sentry VREL control valve is the industry standard for samples greater than 500 psig (34.5 barg) according to the Annual Book of ASTM Standards, ASTM Designation D3370.

FEATURES 
• Ergonomic speed handle substantially reduces turning effort 
• No valve/regulator erosion or wire drawing 
• Fine flow control 
• Fully retractable rods assure easy online purging 
• Extended-body design eliminates possibility of bent tubes 
• Flows from 150 milliliters per minute up to 4 liters per minute at pressure drops up to 5000 psig (345 barg) standard, and 7803 psig (538 bar) for supercritical power plant applications

SENTRY树脂柱RC-100系列介绍
