341 expansion are clamped with clamping groove 33, when rotating swivel becket 345 again, since retracting cylinder 341 and clamping groove 33 are clamped, and, turn
Rotating ring 345 will drive the rotation of rotation seat 31, so that control assembly 2 be driven to rotate, realize the adjusting to 22 position of ball valve；
Ball valve 22 is adjusted: the upper end of control screw rod 21 is sequentially installed with the identical control mechanism 23 of structure and bindiny mechanism
28, and connecting rod 25 is realized by positive stop strip 26 and is not only clamped with control screw rod 21 but also is slidably connected with control screw rod 21,
When runner assembly 3 drives extension rod 29 to rotate, extension rod 29 drives control screw rod by bindiny mechanism 28 and control mechanism 23
21 rotations, control screw rod 21 are connect with the threaded upper ends of connecting tube 1 again, are able to drive on ball valve 22 to control the rotation of screw rod 21
Lower movement, realizes the control of Pipeline transport；
Be pressurized protection: when runner assembly 3 is pressurized, since control mechanism 23, bindiny mechanism 28 and control screw rod 21 are to slide
Dynamic to be cooperatively connected, when being pressurized, runner assembly 3 drives control mechanism 23, bindiny mechanism 28 and connecting plate 210 to move down,
Connecting rod 25 is shunk, under the action of control spring 27 and buffer spring 212, and the pressure that screw rod 21 is controlled when compression can be reduced,
To avoid control 21 compression bending of screw rod and silk phenomenon living；
It adjusts rear protecting: after the completion of 22 position of ball valve is adjusted, pulling pull ring 362, pull ring 362 is by adjusting 361 bands of rope
Dynamic retracting cylinder 341 is shunk, and is then rotated up swivel becket 345 along the direction of arc groove 32, and retracting cylinder 341 and card at this time saves
Slot separation, and sliding slot is entered by arc groove 32, finally, rotation rotating bar 353, so that change divides arc groove 32 and sliding slot
From when rotating swivel becket 345 again, swivel becket 345 only will drive retracting cylinder 341 and rotate in sliding slot, not will drive rotation seat
31 rotations, swivel becket 345 is arbitrarily rotated so as to avoid non-operator influences the normal conveying of pipeline.
Workflow in summary realizes the function of enhancing shut-off valve protective, solves existing shut-off valve and is using
When existing shut-off valve it is buried in use, control-rod, which is pressurized, is easy bending or silk living；When shut-off valve is exposed to surface, it is easy non-
Operator rotates turntable, influences the problems such as pipeline normally conveys, has reached purpose.
The embodiment that the present invention only refers to drawing illustration is illustrated, it is believed that has related fields basic
The personnel of knowledge can carry out the other embodiments of diversified deformation and peer-level based on this.
