Abstract
A fluid transportation device includes a valve body, a valve membrane, a valve chamber seat, an actuator and an outer sleeve. The valve body includes an inlet passage and an outlet passage. The valve chamber seat includes an inlet valve channel, an outlet valve channel and a pressure chamber. The pressure chamber is in communication with the inlet valve channel and the outlet valve channel. The valve membrane is arranged between the valve body and the valve chamber seat. The valve membrane includes two valve plates. The inlet valve channel and the outlet valve channel are closed by the two valve plates. The pressure chamber is covered by the actuator. The outer sleeve has an accommodation space. A ring-shaped protrusion structure is formed on the inner wall of the outer sleeve. Moreover, plural engaging structures are discretely arranged on a periphery of the outer sleeve.
