The first communication hole 11 and the second communication hole 21 can be communicated through the adjusting hole 31, the adjusting hole 31 is driven to move by the movement of the adjusting plate 3, and the overlapping area of the adjusting hole 31 and the first communication hole 11 and the second communication hole 21 is adjusted, so that the opening of the throttling device can be adjusted at will within a range of 0-100%, the purpose of flow adjustment is achieved, the problem that the diameter of an orifice on the throttling orifice plate is fixed and cannot be changed in the prior art is effectively solved, and the adjustment reliability of the throttling device is ensured.
When the throttle device is in the fully opened state, the overlapping area of the regulating hole 31, the first communication hole 11 and the second communication hole 21 is maximized, and at this time, fluid can flow through the first communication hole 11, the regulating hole 31 and the second communication hole 21 in sequence; when the throttle device is in the fully closed state, the overlapping area of the adjustment hole 31 with the first communication hole 11 and the second communication hole 21 is zero, and at this time, the first communication hole 11 and the second communication hole 21 are blocked by the adjustment plate 3 and cannot communicate with each other.
When the throttle device is regulated, the throttle device can be switched between a full-open state and a full-closed state at will, namely the regulating plate 3 can be stopped at any position, so that the opening degree of the throttle device is regulated within the range of 0-100%.
The throttling device further comprises a driving mechanism 4, wherein the driving mechanism 4 is arranged on the inlet plate 1 or the outlet plate 2, and the adjusting plate 3 is connected to the driving mechanism 4.
