In this embodiment, since the fixed disk is in a fixed state and the moving disk is in a moving state, the moving disk rotates in the opposite direction to realize the first hole body. The relative movement of the second sliding plug and the second arc-shaped sliding cavity, that is, in this embodiment, the arc-shaped sliding cavity is in a moving state, and the second sliding plug is in a fixed state, thereby forming a relative rotation; at the same time, an elastic component is provided on the shell, and the elastic component makes the movable disk have a tendency to rotate in the opposite direction, so that the sliding plug slides to between the first hole body and the third hole body, thereby achieving blocking. In this embodiment, the elastic component is an elastic component on the pneumatic valve assembly. When the pressure at the liquid inlet is less than the elastic force of the elastic component, under the action of the elastic force, the second sliding plug rotates in the opposite direction, that is, moves toward the front cavity, and makes the third hole body move to the rear end of the second sliding plug, and the solid first hole body and the third hole body are blocked to achieve closure; therefore, when liquid is introduced, it can be opened directly by the solution pressure instead of by the pneumatic valve assembly to achieve one-way entry; when the solution has no pressure requirement or needs to be depressurized, it can be opened by the pneumatic valve assembly to achieve pressure-free liquid introduction or depressurization.
