It is dynamic to be arranged in the hydraulic punch pressure area 101.The technical program by piston component 24 move up and down change hydraulic stamping
The pressure of hydraulic oil in area 101, to drive clip-connecting rod 41 to move left and right, so as to realize left flap 3 and right flap 4
Close, crush seal circle 5 realizes sealing.
Example IV, as shown in figure 13, the present embodiment and embodiment one are almost the same, and difference is：The valve rod
2 upper end of main body is connected with drag-line 17, and drag-line 17 allows valve rod by the dragging realization for being arranged in the power source 19 of 18 side of pulley
The movement of main body 2 in the vertical direction.Such side provides a larger pulling force and is pulled to stem body 2, especially suitable
The scene larger for pressure.
Embodiment five, as shown in figure 14, the present embodiment and embodiment one are almost the same, and difference is：Stem body 2
Upper end is connected with drag-line 17, and drag-line 17 is by a pressure-bearing pulley 102 and is wrapped on pressure-bearing pulley 102, pressure-bearing pulley 102 1
Side is connected with lift pressure lever 103；The pressure-bearing pulley 102 is installed in pressure-bearing babinet 104.
In actual use, by lifting or pushing lift pressure lever 103, to drive the rotation of pressure-bearing pulley 102,
And then drag-line 17 can be rotated around driving pressure-bearing pulley 102, and then driving stem main body 2 moves up and down, to realizing
Sealing function of the present invention.The present embodiment is somewhat like with example IV, and difference is the mode of driving drag-line 17 not
Together.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：It is all according to
The equivalence changes that structure, shape, the principle of the present invention is done, should all be covered by within protection scope of the present invention.
