Vacuum breaker valve

A vacuum breaker valve comprising:

• a valve body;
• and
• a vacuum breaking device mounted in the valve body;
• wherein:
• the valve body has a periphery provided with multiple air vent holes corresponding to the vacuum breaking device;
• the vacuum breaking device includes a mounting barrel, an elastic member, a braking member, a mounting plate, a water stop gasket, and a water inlet disk;
• the mounting barrel is a hollow cylinder;
• the mounting barrel has an interior having a bottom face provided with a stepped rim;
• the mounting barrel has a lower end provided with a first flange;
