Abstract (en)
[origin: WO2018233978A1] The present disclosure concerns a sealing device that consists of a base (1) and a cover (2), and it has the following characteristics: The base's upper end has a mating hole (2) with internal thread, the cover's lower end has an extension part with external thread. The base and the cover are connected through thread on the mating hole and the extension part. The extension part has an internal baffle (8), and there is a lug (11) on the baffle. The cover's lower end face has a ring slot, in which a seal ring (5) is placed; edge of the base's upper end has a lower connecting hole (9), and the cover's upper end face has an upper connecting hole (6). The upper connecting hole and the lower connecting hole are connected by a connecting piece. This solution can effectively seal up the mating hole, prevent the materials within it from suffering external contaminants, thus increasing the logistical safety and reliability.
