The present invention discloses a fluid regulator that can achieve a low outlet pressure and a steady outlet flow under large outlet flow. The regulator comprises a valve body, a pressure-regulating device and a balance device. The valve body has an inlet fluid pressure cavity, an outlet fluid pressure cavity, and a throttling orifice in fluid communication with the inlet fluid pressure cavity and the outlet fluid pressure cavity. The pressure-regulating device comprises a lever, a sealing device connected to a first end of the lever and a diaphragm assembly connected to a second end of the lever. The balance device comprises a balance hole and a balance member. The balance hole is provided on the valve body, wherein the balance hole is positioned at one side of the lever fixing device and the throttling orifice is positioned at the other side of the lever fixing device. The balance member and the balance hole are provided at a same side of the lever fixing device and configured so that a fluid from the inlet fluid pressure cavity can exert a force on the second end of the lever via the balance hole and the balance member. |
