Through adopting above-mentioned technical scheme, the setting of second spring lets have restoring force between first expansion plate and the second expansion plate, and after the second expansion plate upwards moved a section distance, just can drive first expansion plate upwards to remove.
The utility model is further provided with: the lower extreme of connecting rod sets up to the T form, the upper end of first expansion plate is provided with the T form groove that is used for the connecting rod card to go into.
Through adopting above-mentioned technical scheme, the lower extreme and the first expansion plate joint back of connecting rod, the connecting rod can drive first expansion plate and remove.
The utility model is further provided with: the valve seat is characterized in that a valve cover is arranged above the valve seat, a double-end stud is arranged between the valve cover and the valve seat, nuts are connected with the two ends of the double-end stud in a threaded mode, and a winding gasket is arranged on one side of each nut.
Through adopting above-mentioned technical scheme, after the valve gap is in the disk seat, place the double-end stud between valve gap and disk seat, rotatory nut utilizes double-end stud and nut fixed valve gap and disk seat, twines the cushioning effect of gasket.
In summary, the utility model has the following beneficial effects:
the valve rod moves downwards to drive the first expansion plate and the second expansion plate to move downwards, when the lower end of the second expansion plate moves to be extruded with the module, the second expansion plate stops moving, then the second expansion plate continues to move downwards, and because the inclined plane exists, the first expansion plate and the second expansion plate move towards the direction away from each other, and the movement of the first expansion plate and the second expansion plate can drive the first valve plate and the second valve plate to move towards the direction away from each other, so that the effect of closing a pipeline is achieved.
