SENTRY控制阀VREL产品介绍
现代发电厂中水和蒸汽样品的化学分析需要精确控制流量和压力。但是，高压降低的需求可能会带来采样问题。获得专利的Sentry VREL控制阀是专门为解决独特的高压采样问题而设计的。
Sentry VREL控制阀由连接到大管子或枪管的两个不锈钢管组成。将锥形杆组件插入到枪管的精密孔中。高压流体进入，流过一个杆，旋转并流过另一杆，然后流出。压降是插入杆中长度的函数。在层流条件下，压力平稳降低，通过不连续的压降将任何组分的离解降至最低。旋转旋钮可从外部控制杆的位置，并可在样品流动时对其进行调节。如果发生堵塞，则杆可以缩回，因此系统压力可以吹走固体物质。
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 patented Sentry VREL control valve is specifically designed to solve unique high-pressure sampling issues.
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.
