Rotation, the effect of two stop collar I3-4 are to prevent the relatively intermediate protrusive board 3-1 of two-flight screw 3-2 from moving left and right, double thread spiral shell
Bar 3-2, which is rotated back to using own axes as axis, drives two threaded hole block 2-3 close to each other or separate simultaneously, thus control two
Slip joint 2 is close to each other or separate.It can drive driving screw 4-3 on portal frame 4-2 with itself when turn hand capstan 4-4
Axis is axis rotation, and the effect of two stop collar II4-5 is to prevent driving screw 4-3 with respect to portal frame 4-2 vertical sliding, driving screw
4-3 can drive main gate-board 4-7 to move up and down when rotating using own axes as axis, main gate-board sealing ring 4-6 in upper cover plate 4-1 and
The position that is slidably connected of main gate-board 4-7 plays the role of sealing, when raised line 4-8 is fully inserted into raised line slot 1-5, this duration
It can not be at this moment equivalent to closing valve by water in square box 1-1, water can not flow to the other end from the slip joint 2 of one end
Slip joint 2.When turn hand-screw 5-4 is rotated using own axes as axis, hand-screw 5-4 can drive slotting slide 5-1
It is slid back and forth on circle rail bar 5-3, drives two cross bar 5-2 to slide back and forth to insert slide 5-1, two drive two pairs respectively
Flashboard 2-8 slides back and forth, thus hand-screw 5-4 can control two auxiliary gate-board 2-8 into and out and working as main gate-board
When 4-7 damage can not obstruct water flow, two auxiliary gate-board 2-8 can be closed two auxiliary gate-board slot 2-9, at this moment can repair master
Flashboard 4-7 improves the safety of valve.Two cross bar 5-2 can horizontally slip on slotting slide 5-1, thus when two
The distance between slip joint 2 change when, insert slide 5-1 can still drive two auxiliary gate-board 2-8 into and out.It needs completely
When closing valve, two auxiliary gate-board 2-8 and main gate-board 4-7 can be turned off, to improve the safety of valve closing.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made within the essential scope of the present invention also belong to guarantor of the invention
Protect range.
