衬氟蝶閥

衬氟蝶閥主要分为全衬里型和半衬里型，全衬里型衬氟蝶閥采用对分两片式阀体组合，阀座与阀体内衬一体化，閥門工作时，只有全塑阀座与衬塑蝶板与介质接触，产品可承受“除熔融碱金属和元素氟”外的任何介质腐蚀。阀体通道内表面光滑，流体阻力小，CV值高，流通能力强，扭矩适中，采用四级密封结构并在密封面外配以耐温抗老化的SI橡胶的弹性衬垫阀座，完全达到介质的零泄漏。

半衬里型衬氟蝶閥是在全衬氟蝶閥的扩展产品，阀体全衬里，蝶板为不锈钢材质。

特點總結：

襯氟工藝耐腐蝕性能優異有效替代不锈钢蝶閥最高溫度150℃

go top When the Doctor had finished his eulogy upon the Japanese, the boys clapped their hands, and were evidently touched with his enthusiasm. From the little they had seen since their arrival in the country, they coincided with him in opinion, and were ready to endorse what he said. And if they had been in any doubt, they had only to refer to the great majority of foreigners who reside in Japan for the confirmation of what the Doctor had declared. Testimony in this matter is as nearly unanimous as it is generally possible to find it on any subject, and some of the foreign residents are ready to go much further in their laudations of the kindly spirit of the natives than did Doctor Bronson. The reply came slowly. "No; her husband is quite another man; this man's wife has been dead for years. No, Charlotte Oliver lives in--hark!" The history of Greek philosophy, whether conceived in this comprehensive sense or as an erudite investigation into matters of detail, is a province which the Germans have made peculiarly their own; and, among German scholars, Dr. Zeller is the one who has treated it with most success. My obligations to his great work are sufficiently shown by the copious references to it which occur throughout the following pages. It is in those instances—and they are, unfortunately, very numerous—where our knowledge of particular philosophers and of their opinions rests on fragmentary or second-hand information, that I have found his assistance most valuable. This has especially been the case with reference to the pre-Socratic schools, the minor successors of Socrates, the earlier Stoics, the Sceptics, and the later Pythagoreans. I must, however, guard against the supposition that my work is, in any respect, a popularisation or abridgment of Zeller’s. To popularise Zeller would, indeed, be an impertinence, for nothing can be more luminous and interesting than his style and general mode of exposition. Nor am I playing the part of a finder to a large telescope; for my point of view by no means coincides with that of the learned German historian. Thus, while my limits have obliged me to be content with a very summary treatment of many topics which he has discussed at length, there are others, and those, in my opinion, not the least important, to which he has given less space than will be found allotted to them here. On several questions, also, I have ventured to controvert his opinions, notably with reference to the Sophists, Socrates, Aristotle, and Plotinus. My general way of looking at the Greeks and their philosophy also differs from his. And the reasons which have led me to follow an independent course in this respect involve considerixations of such interest and importance, that I shall take the liberty of specifying them in some detail. So I had to get out and take the next car, and was late for gymnasium. and regular classes keep you alive mentally, and then when your “There’s no life preserver in the boat either—so that’s what the mystery man used to swim away with—Mr. Everdail’s jewels!” he added. "But not now!" cried Caro. HoME 98人体av ENTER NUMBET 00951fx.org.cn
