Patent number: 11953153Abstract: A high-pressure gas cylinder valve for vehicle includes a valve seat having a gas charging runner and a gas supplying runner. A check valve is connected in series onto the gas charging runner, and the check valve and a solenoid valve are connected in series sequentially onto the gas supplying runner in a gas flow direction. A portion of the gas supplying runner located downstream of the solenoid valve is jointly connected to a portion of the gas charging runner adjacent to a gas inlet end and supplies gas to outside through a gas inlet of the gas charging runner when the gas supplying runner supplies gas. The gas cylinder valve further includes a flow-blocking buffer structure connected in series onto the gas supplying runner and located downstream of the solenoid valve and upstream of an intersection of the gas supplying runner and the gas charging runner.Type: GrantFiled: December 28, 2021Date of Patent: April 9, 2024Assignee: YAPP AUTOMOTIVE PARTS (KAIFENG) CO., LTD.Inventors: Guanghui Tan, Lin Jiang, Shaowen Hu, Yinchun Liu, Xiaoqiong Dong, Kaige He

Publication number: 20240003463Abstract: A solenoid valve and a vehicle gas cylinder valve having the solenoid valve are provided. The solenoid valve includes a casing, a pilot head, a main valve seat, and a pilot valve core. An outer peripheral surface of the casing is provided with a clearance fit surface, and the clearance fit surface is configured for clearance fit with a solenoid valve installation passage to form a bypass gas passage between the casing and the solenoid valve installation passage. The casing is provided with an upper casing ventilation hole and a lower casing ventilation hole. The upper casing ventilation hole communicates with an upper portion of the bypass gas passage and a pilot head upper chamber, and the lower casing ventilation hole communicates with a lower portion of the bypass gas passage and a pilot head lower chamber.Type: ApplicationFiled: June 29, 2023Publication date: January 4, 2024Applicant: YAPP AUTOMOTIVE PARTS (KAIFENG) CO., LTD.Inventors: Guanghui TAN, Shaowen Hu, Lin Jiang, Yinchun Liu, Kaige He

Publication number: 20160060394Abstract: The present invention belongs to the field of preparation of high performance polymers, and specifically relates to a low dielectric constant polymer containing dinaphthyl and hexafluorocyclobutyl ether units, and preparation method and use thereof. The polymer is prepared as follows: under the effect of an alkali, 1-naphthol bromotetrafluoroethane ether is prepared from 1-naphthol and tetrafluorodibromoethane in an organic solvent, and then reduced by a zinc powder so as to obtain 1-naphthol trifluorovinyl ether. 1-naphthol trifluorovinyl ether is treated at a high temperature to obtain a bisnaphthol hexafluorocyclobutyl ether monomer. The monomer is subjected to oxidative coupling in the presence of ferric trichloride so as to obtain a thermal polymer containing dinaphthyl and hexafluorocyclobutyl structural units with a good film-forming property, and in a nitrogen atmosphere, the temperature for 5% weight loss (Td5%) of the obtained film is 437° C., and the carbon residue yield at 1000° C. is 54.24%.Type: ApplicationFiled: November 20, 2013Publication date: March 3, 2016Inventors: Qiang FANG, Chao YUAN, Kaikai JIN, Yinchun LIU, Shen DIAO, Kai LI
