Abstract: 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.

Abstract: 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.

Abstract: The disclosure relates to a pressure regulating device for vehicle. A gas pressure regulating device for vehicle includes a valve seat and a valve cavity housing. The valve seat is provided with a valve core insertion hole, and a bottom of the valve core insertion hole is provided with a valve port. The valve cavity housing is detachably assembled with the valve seat. A valve core is guided and assembled in the valve cavity housing, the valve core has an inserted segment, the inserted segment is inserted in the valve core insertion hole, and the valve core is provided with a flow channel. An insertion sealing ring is provided between a hole wall of the valve core insertion hole and an outer peripheral surface of the inserted segment of the valve core. The valve seat and the valve cavity housing are relatively translated in an axial direction of the valve core insertion hole and are assembled in place in a relatively translational manner.
