On August 6, 2019, the world’s first intelligent, telescopic, frictionless ball valve, developed jointly by Institute 11 of China Aerospace Science and Technology Corporation and the South China Branch of Sinopec Marketing Co., Ltd., was successfully put into use at the company’s Zhongshan oil transfer station. All the parameters of this telescopic frictionless ball valve are superior to those of conventional ball valves; it is suitable for harsh environments with flammable and explosive substances as well as high levels of impurities, meets fire and explosion prevention requirements, and can be widely used in various industrial enterprises. At the same time, in the event of an emergency, it can shut down both the upstream and downstream sections simultaneously, creating an independent zero-leakage seal that provides strong protection for the safety of the pipelines; this represents further progress in China’s capabilities in terms of independent innovation in long-distance pipeline systems. It is understood that this new type of telescopic frictionless ball valve features a completely new four-valve disc main valve structure as well as a dual-screw drive mechanism. It overcomes the problems associated with traditional ball valves, such as high operating torque, internal leakage caused by scratches on the sealing surfaces, tendency to get stuck, short service life, poor resistance to contamination, inability to be repaired online or to have leaks detected, and inaccurate indication of the valve position. It represents a significant innovation.
