Specific embodiment
Specific embodiment of the present utility model is described with reference to the accompanying drawing.
It as shown in Figures 1 to 7, is a kind of pneumatic power lifting valve of the present embodiment, including cylinder 1 and valve plate 2, the work of cylinder 1
Stopper rod outer end is equipped with screw thread, and valve plate 2 is anchored on screw thread by being located at the nut 3 of its two sides, is coaxially provided with one on nut 3
Annular groove 4,4 internal screw thread of annular groove are connected with a turning set 5, and the end of turning set 5 is equipped with end cover 6, sets on end cover 6
There is the mounting hole 7 that the piston rod for cylinder 1 passes through, forms rotation stop chamber 8 between turning set 5 and nut 3, be located on end cover 6
Rubber sleeve 9 is equipped in rotation stop chamber 8, rubber sleeve 9 is equipped with the through-hole 10 passed through for the piston rod of cylinder 1, and rubber sleeve 9 is substantially in circle
Bench-type, nut 3 are equipped with the conical surface 11 matched with rubber sleeve 9.
Opening 12 is radially equipped on rubber sleeve 9, opening 12 is uniformly distributed along the circumferential direction of rubber sleeve 9.
Rotation stop set 13 is also arranged on turning set 5, edge is axially arranged with sliding slot 14, rotation stop set 13 on the outer wall of turning set 5
Inner wall be equipped with the sliding block 15 that matches with sliding slot 14, the inner wall of annular groove 4 includes that inner sidewall 16 and diameter are greater than inside
