in addition, it should be noted that, through the above arrangement, when the positioning disk 1101 rotates, the thin wall expands gradually, when the thin wall expands to be in engagement with the inner wall of the chute 123 and can drive the first connecting column 121 to rotate, the first connecting column 121 rotates immediately, so that the reference disk 1161 rotates along with the first connecting column 121, thus the thin wall pressurization adjustment of the expansion oil cavity 1102 is completed, and the pressurization can be automatically stopped when the required expansion degree can be reached, so that the expansion adjustment of the thin wall is simpler and more convenient, and the situation that the first connecting column 121 cannot be driven to rotate due to insufficient expansion of the thin wall when the thin wall is expanded, and the situation that the positioning disk 1101 cannot slip and cannot play a role in protecting the valve rod when the torsion is overlarge due to overlarge expansion of the thin wall is avoided;
therefore, when the valve rod is blocked and cannot rotate, the worker rotates the rotating wheel, and the first connecting column 121 cannot rotate, and the second connecting column 122 can slide in the sliding groove 123 due to forced rotation of the worker, so that the valve rod is protected, and the worker then dismounts and maintains the valve 2;
in addition, in order to prevent the thin wall from being tightly attached to the sliding groove 123 due to continuous pressurization after the positioning disk 1101 is slipped by forcibly rotating the connecting post two 122 when the valve rod is blocked and cannot rotate, the rotation direction of the valve rod and the rotation direction of the expansion screw 1104 are configured such that when the rotating wheel is in forward rotation, the valve rod is in forward rotation to drive the valve seat to rise, and when the rotating wheel is in forward rotation, the connecting post one 121 is in static rotation, the expansion screw 1104 is rotated downwards, so that when the valve 2 is opened, the forward rotating wheel rotates the valve rod, so that the valve 2 is lifted to open the valve hole, and when the valve rod is blocked, the valve 2 is opened by a worker, the forward rotating wheel is connected to the connecting post one 121, the valve rod cannot rotate due to the blocking of the valve rod, the expansion screw 1104 is rotated downwards due to the forward rotation of the positioning disk 1101, the internal expansion oil chamber 1102 is depressurized to avoid the thin wall being continuously pressurized to cause the thin wall to be more tightly attached to the sliding groove 123, in addition, it is to be noted that when the valve seat of the valve 2 is set in an opened state, a gap is left between the valve seat of the valve 2 and the inner wall above the inner cavity of the valve 2, in other words, when the valve 2 is in an opened state, the valve rod has a margin for continuously moving upwards, therefore, when the valve rod is blocked when the valve 2 is opened, the valve rod is blocked, the staff continuously rotates the rotating wheel forward to test the movable looseness condition of the valve rod, when the valve rod is not blocked, the staff reversely rotates the rotating wheel to enable the valve rod to reversely rotate, so that the valve seat is lowered to cover and seal the valve hole, and when the valve rod is blocked, the staff forcibly rotates, the positioning disk 1101 is slipped, so that the expansion screw 1104 moves downwards to relieve the pressure of the expansion oil chamber 1102, so that the thin wall is reset, after the maintenance is finished, the operator can overhaul the valve rod of the valve 2, and after the maintenance is finished, the operator rotates the rotating wheel reversely, and because at the moment, the positioning disk 1101 is reset by the thin wall, the positioning disk 1101 slides in the chute 123, and therefore, the positioning disk 1101 rotates reversely to enable the expansion screw 1104 to rotate upwards to pressurize the expansion oil cavity 1102, so that the thin wall is expanded, when the expansion disk 1101 is expanded to drive the first connecting column 121 to rotate, the reference disk 1161 rotates along with the first connecting column 121, so that the expansion screw 1104 does not continue to move upwards, the pressurization is automatically finished, and then the first connecting column 121 rotates to enable the valve rod to rotate, so that the valve seat moves downwards to seal the valve hole, and therefore, the positioning disk 1101 can be reused.
The principle of the invention is as follows: when the valve 2 is buried, the valve 2 is firstly placed in a pit, then the connecting column II 122 is pulled upwards, so that the connecting column II 122 drives the rotating wheel to move to the ground surface, after the height of the rotating wheel is determined, the rotating wheel is reversely rotated, the thin wall of the positioning disk 1101 is not expanded, so that the positioning disk 1101 can rotate in the chute 123, the rotating wheel reversely rotates to drive the positioning disk 1101 to reversely rotate in the chute 123, the positioning disk 1101 can not drive the connecting column I121 to rotate, in addition, the reference disk 1161 is limited with the chute 123 through the limiting plug 1163 and the limiting slot 1164, so that the reference disk 1161 can not rotate in the connecting column I121 alone, when the positioning disk 1101 reversely rotates, the expansion screw 1104 is kept stationary, the expansion screw 1104 can move up in the positioning disk 1101 and move up the piston 1105, thus pressurizing and expanding the thin wall, when the positioning disk 1101 can drive the first connecting column 121 to rotate, the reference disk 1161 rotates along with the first connecting column 121, so that the expansion screw 1104 does not move upwards continuously, pressurizing is automatically completed, then the first connecting column 121 rotates to enable the valve rod to rotate, so that the valve seat moves downwards to close the valve hole, then when the valve 2 needs to be opened, the wheel is directly rotated forwards, so that the second connecting column 122 drives the first connecting column 121 to rotate forwards, so that the valve rod rotates upwards, so that the valve seat moves upwards to open the valve hole, when the valve 2 is in an open state, the valve seat needs to be closed, because the valve seat has a margin for continuing to move upwards, a worker can rotate the rotating wheel forwards firstly, so that the valve seat moves upwards, thereby testing the looseness of the valve rod, the valve seat can move upwards smoothly under the condition that the valve rod is not jammed, and the staff pulls the rotor upwards and can not pull, this moment indicates that the positioning disk 1101 keeps the inflation state, then the staff reverses the rotor, thereby make the valve rod reverse, make the disk seat descend and cover the valve opening sealed, and under the circumstances that the valve rod is blocked, the staff rotates under the test valve rod rotation looseness by force, can make the positioning disk 1101 skid, thereby make the expansion screw 1104 move down to the expansion oil pocket 1102 release, therefore, make the thin wall reset, the staff pulls the rotor upwards and can make spliced pole two 122 move upwards, this moment indicates that the thin wall of positioning disk 1101 resets, that is, the valve rod is blocked and is difficult to rotate, this moment the staff can overhaul and maintain valve 2, after the maintenance is accomplished, reverse the rotor, make the positioning disk 1101 expand and move down to the valve opening seal simultaneously, and when valve 2 is closed, the same as above-mentioned step, forward rotate the rotor, later will rotate the rotor upward, it indicates that the valve rod is blocked, the rotor can't move upward, and indicate that the valve rod is normal.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
