石油化工设备用的阀门品种多、数量大、工作温度高、要承受一定的压力和防蚀要求,是一个很关键的部件。石油化工设备中的阀门由于缺乏合适的密封件而造成“跑、冒、滴、漏”,影响安全生产和浪费昂贵的原材料。以往,靠进口柔性石墨密封件来解决。上海材料研究所研制成功的新型柔性石墨板材和密封元件,经有关石油化工厂使用,性能良好。1979年9月20日至22日由一机部机械科学研究院在上海召开了柔性石墨密封件技
Petrochemical equipment with many valves, large quantities, high temperature, to withstand a certain pressure and corrosion requirements, is a key component. Valves in petrochemical plants “run, run, drip and leak” due to lack of suitable seals, affecting safe production and wasting expensive raw materials. In the past, imported flexible graphite seals to solve. Shanghai Institute of Materials developed a new flexible graphite sheet and sealing components, the petrochemical plant by the relevant, good performance. September 20, 1979 to 22 by a Machinery Research Institute of Machinery held in Shanghai, a flexible graphite seal technology
