此取祥阀供给了一个简略、 宁静的采样体例，对样品取样到达零净化程度。阀门实质是针形阀。用于在节制流量的前提下从管道中取样。在设想上支配了多重密封布局（已请求专利），以完成压盖局部零泄露。物料与阀体内部打仗资料均为PFA材质，保障其耐侵蚀性，其他部件材质接纳不锈钢制作，到达阀门的表里外表都具备杰出的卫生干净度，从而在须要洁净任务的情况中最大限制地削减净化。 阀门上方设有下压操纵手柄， 可轻松谨慎翻开阀门取样。经由过程适配差别取样瓶四氟座装置硼硅酸盐玻璃瓶能够用于程度或垂直管道体系中。在操纵把手和阀体机架处设有宁静锁孔，避免有关职员停止随便操纵，现场节制更宁静。

     The sampling valve provides a simple and safe sampling method which has zero contamination to the sample. It is actually a needle valve, which is used to take sample from the pipeline under the condition of controlled flow Multiple sealing structures (patented) are designed to achieve zero leakage in gland. The valve body contacting with sampling medium is made of PFA to ensure its corrosion resistance and the rest of the components are made of stainless steel, so that the inner and outer surfaces of the valve have good hygiene and cleanliness, which minimizes contamination in environments where clean work is required. There is a push-down operating handle above the valve, which can easily and carefully open the valve for sampling. Borosilicate glass bottles can be used in horizontal or vertical piping systems by fitting different sampling bottles with Teflon seats. Safety keyhole is provided at the operating handle and valve body frame to prevent irrelevant personnel from arbitrarily operating, and the on-site control is safer.
