Abstract
A fluid transportation device includes a valve cover, a valve body, a valve membrane and a valve chamber seat. The valve cover has two openings. The valve body includes an inlet passage and an outlet passage. The valve membrane is arranged between the valve body and the valve chamber seat, having two valve plates respectively close an inlet valve channel and an outlet valve channel of the valve chamber seat. The valve chamber seat forms a pressure chamber which is sealed and covered by an actuator. The valve cover is sleeved on the valve body and tightly fitted to the inner wall of an outer sleeve to assemble the device, in which a first gasket is disposed between the valve body and the valve membrane, and a second gasket is disposed between the valve membrane and the valve chamber, by which sealing effect is improved and backflow is prevented.
