Patent number: 11313480Abstract: Disclosed is a valve mechanical linkage system. A valve comprises a main valve and a secondary valve; the system comprises a first transmission mechanism and a second transmission mechanism; the first transmission mechanism is connected with the main valve and used for converting the up-and-down reciprocating motion of the main valve into a rotational reciprocating motion; the first transmission mechanism and the second transmission mechanism are connected by means of a coupling (4), and the rotational force of the rotational reciprocating motion is transferred to the second transmission mechanism by means of the coupling (4); the second transmission mechanism is connected with the secondary valve, and achieves on-off control on the secondary valve by converting the rotational reciprocating motion into the up-and-down reciprocating motion.Type: GrantFiled: January 28, 2019Date of Patent: April 26, 2022Assignees: Beijing Aerospace Propulsion Institute, Beijing Aerospace Petrochemical Technology & Equipment Engineering Corporation LimitedInventors: Fan Yang, Qingzhao Yang, Yingren Ding, Jingbo Han, Jin Guo, Xiang Su, Jinxian Liu, Huan Yang, Qiang Li, Yusheng Guo

Patent number: 11131395Abstract: A double-plate gate valve includes a valve body, a valve cover, a valve stem, a guide plate, a goggle plate assembly, a diversion hole assembly, a disc spring assembly and a valve plate and wedge assembly. The goggle plate assembly provides mounting support for the diversion hole assembly and the valve plate and wedge assembly in the valve chamber, the goggle plate assembly is movable along with the diversion hole assembly and the valve plate and wedge assembly in the valve chamber, and floating seals are formed at a contact surface between the diversion hole assembly and the guide plate, and at a contact surface between the valve plate and wedge assembly and the guide plate. A face-to-face distance and a sealing force between a sealing surface of the diversion hole assembly and a sealing surface of the valve body are adjustable.Type: GrantFiled: January 28, 2019Date of Patent: September 28, 2021Assignees: BEIJING AEROSPACE PROPULSION INSTITUTE, BEIJING AEROSPACE PETROCHEMICAL TECHNOLOGY & EQUIPMENT ENGINEERING CORPORATION LIMITEDInventors: Fan Yang, Jinxian Liu, Yingren Ding, Jin Guo, Xiang Su, Huan Yang, Jingbo Han, Pingyang Zheng

Publication number: 20210172669Abstract: The present disclosure provides a refrigerator including a vacuum sealing device disposed at an outer side of a door. The vacuum sealing device includes a lower support, an upper support and a vacuumization assembly. The upper support moves close to or away from the lower support under the drive of a driving device; after the upper support moves at a first speed until a sealing ring of the upper support is in contact with a sealing ring of the lower support, the upper support moves at a second speed toward the lower support until the sealing ring has a set deformation amount, and a first opening cavity and a second opening cavity are butt-joined to sealingly form a vacuumization region; the first speed is greater than the second speed; the vacuumization assembly is in communication with the vacuumization region through a pipe to perform vacuumization or depressurization for the vacuumization region.Type: ApplicationFiled: February 22, 2021Publication date: June 10, 2021Inventors: Meiyan WANG, Junwang YAN, Yongyi JIN, Jiangao ZHU, Guanghua LUO, Jingbo HAN, Fuzhen LIU, Shanfang ZHANG
