| description | The low-flow-resistance totally-closed flow channel structure comprises a valve body and balls arranged in the valve body, the valve body comprises a cavity I and a cavity II which are integrally arranged from left to right, the cavity I is communicated with the cavity II, the balls comprise the ball I and the ball II, the ball I is installed in the cavity I through a sealing assembly I, and the ball II is installed in the cavity II through a sealing assembly II. A valve rod I for driving the ball body I to open and close is arranged on the ball body I; the ball body II is installed in the cavity body II through the sealing assembly II, a valve rod II used for driving the ball body II to be opened and closed is arranged on the ball body II, and the ball body II is a corner ball. The integrated valve body, the eccentric corner ball and the closed flow channel are adopted, so that the medium flow capacity of the valve is improved, and the size and the weight of the valve are reduced; the marine key valve solves |
