The invention relates to the technical field of improved fuel tank isolating valves. According to the improved two-stage fuel tank isolation valve, the stepping motor is integrated so that the pressure can be maintained within the pressure protection range, two-stage electric control can be carried out on fuel steam through multiple steps, and therefore air flow of the fuel steam from the fuel tank to the storage tank can be opened in the refueling process, and the functions of pressure relief and vacuum pressure relief are provided.
本发明涉及一种改良式燃料箱隔离阀技术领域。本发明提供的一种改良的二段式燃料箱隔离阀,整合一步进马达以使压力维持在压力保护范围内,并通过多个步骤对燃料蒸气进行二段式电控,从而在加油过程中开启从燃料箱到储罐的燃料蒸气的气流,并提供释压及真空释压的功能。
