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.
