Abstract

PURPOSE: To equalize the pressing action of the gate component material to the seal ring and prevnet the damage of the seal ring resulted from the heaving motion of the gate component material, and furthermore enable to open and close the gate quickly and also easily.
CONSTITUTION: When the handle 13 is turned by about 90 deg. and an arc-shaped end portion 19 of the shaft 12 is removed from the channel 15, it becomes possible to drive the shaft 12 into the longitudinal hole. By pushing the shaft 12 downwards, the wedge piece 8 comes down smoothly being lightly in contact with the seal ring 4. The screw of the handle 13 and the screw of flange 16 is interconnected under the condition where the wedge peice 8 is brought down to the lowest limit, and the gate component material is forwarded by the amount of the pitch of the screw by turning the handle 13. When the wedge piece 8 is butted on the bottom of the longitudinal hole, the pin 9 pushes the wedge piece 8 perpendicular to the seal ring 4 by compressing the spring 10 and by the wedge action of the closing piece 7 to the wedge piece 8.
