今年年初,我们在某小型试验装置上,需安装一个耐压硬质玻璃管,以便计量环氧乙烷,因为设备内有一定压力,又有些震动,所以玻璃管的密封处,不宜采用通常的螺纹盘根密封,如用钢质卡套,不仅密封不好,且易压碎玻璃管,于是就着手试制塑料卡套,制成后经在装置上使用情况良好。一、塑料卡套简介: 1.塑料卡套材质:采用填加几种填料的聚四氟乙烯。 2.卡套加图1所示。
At the beginning of this year, we needed to install a pressure-resistant hard glass tube on a small test device to measure ethylene oxide. Because there is a certain pressure in the equipment and there is some vibration, the seal of the glass tube should not be used as usual. Threaded packing seals, such as steel ferrules, not only do not seal well and can easily crush the glass tube, so they begin trial production of plastic ferrules, which are then used on the device in good condition. First, the plastic card sets Introduction: 1. Plastic card sets material: the use of filler filled with PTFE. 2. Card sleeve plus Figure 1 shows.
