The valve rotates the driving member 30 clockwise from the opened state to the closed state, as shown in fig. 17, the second driving surface 3122 abuts against the second starting portion 2321, so that the guiding rib 33 pushes the second guiding sub-module 222 to realize that the driving member 30 drives the valve core 20 to rotate along the radial direction of the channel 11, when the valve core 20 rotates to the state switching position as shown in fig. 4, the valve core 20 faces the cross section of the channel 11, the axis of the valve core 20 is almost the same as the extending direction of the channel 11, and the guiding column 21 is located at the opening of the guiding groove 13. Continuing to rotate the driving member 30 in the forward direction, as shown in fig. 18, due to the existence of the limiting edge 14, and when the position is switched, the first valve core limiting rib 271 abuts against the housing limiting rib 111, the second driving surface 3122 rotates in the forward direction and slides along the second starting portion 2321 until being matched with the second limiting portion 2323, at this time, the valve core 20 is pushed by the guiding rib 33 to move towards the direction axis of the inner valve seat 40 to press the inner valve seat 40, and the guiding column 21 slides into the guiding groove 13 from the opening of the guiding groove 13, so as to realize the closing of the valve.

When the valve needs to be opened after the valve is closed, the driving member 30 is rotated anticlockwise, as shown in fig. 19, the first driving surface 3112 is abutted against the first starting portion 2311, the first driving surface 3112 slides along the first starting portion 2311 to cooperate with the first limiting portion 2313 as shown in fig. 20, the first driving surface 3111 cooperates with the first terminating portion 2312, the connection between the first driving surface 3112 and the first driving surface 3111 is located between the first limiting portion 2313 and the first terminating portion 2312, and in this process, the guiding rib 33 pushes the first guiding sub-module 221 to move the valve core 20 towards the direction axis far away from the inner valve seat 40, so that the guiding post 21 slides out from the guiding slot 13, the valve core 20 and the inner valve seat 40 will not be in close contact with each other, and the following rotation movement of the guiding valve core 20 is performed. Continuing to rotate the driving member 30 counter-clockwise, the guiding rib 33 pushes the first guiding sub-module 221 to rotate the valve core 20 counter-clockwise, and at this time, the valve core 20 rotates along the radial direction of the channel 11, so that the valve is gradually opened.

In this embodiment, the valve core 20 cooperates with the inner valve seat 40 to close the valve, that is, the valve core 20 presses the inner valve seat 40 toward the container side to close the valve, and in other embodiments, the valve core 20 presses the inner valve seat 40 toward the valve cover 80 to close the valve. At this time, the inner valve seat 40 may also be fixed by the inner valve seat fastening member 12, and the fixing area of the inner valve seat fastening member 12 to the inner valve seat 40 may be adjusted according to the direction in which the valve core 20 presses the inner valve seat 40.

The valve can be installed on the container to prevent the liquid in the container from flowing out when the valve is closed, and the liquid in the valve can flow into the channel 11 in the valve through the channel in the flange 50 to be discharged when the valve is opened. When the valve is closed, the valve core 20 presses the inner valve seat 40 towards the container direction, and abuts against the inner valve seat 40 to close the channel 11, and at this time, the valve core 20 is operably subjected to liquid pressure, and the direction of the liquid pressure is opposite to the direction that the valve core 20 presses the inner valve seat 40.
