摘要
对普遍采用的以橡胶O形环作为自紧密封件的高压快开密封装置密封部位的结构进行了改进,彻底解决了橡胶O形环在卸压后发生膨胀,将筒体端部法兰与密封盖卡死的问题。开发出了1种新的组合密封环,该密封环可广泛用于超临界萃取装置上。
Seal site structures of high pressure quick open seal in which elastomeric Oring are adopted as selftight seal components have been modificatedThe problem of sealing cover are squeezed by vessel end flanges because of elastomeric Oring expansion after pressure relieving has been solved competelyA new type of combined seal components which possess features of easy ,quick handling and long life has been exploited
