Detailed Description
The invention is described in further detail below with reference to the drawings.
As shown in fig. 1-5, a valve sleeve dismounting tool with a thread on the top comprises a screw 1, an outer sleeve 2, a screw sleeve 3, a clutch chuck 4, a nut 5, a small spring 6, a thrust bearing 7 and a large spring 8;
the large spring 8 is arranged on the screw rod 1, the threaded sleeve 3 is sleeved on the polished rod section of the screw rod 1, the clutch chuck 4 is sleeved on the polished rod section at the leftmost end of the screw rod 1, the small spring 6 is sleeved on the screw rod 1, the thrust bearing 7 is arranged, the nut 5 is screwed on the thread at the left end of the screw rod 1, and finally the outer sleeve 2 is screwed into the screw rod 1 through the internal thread.
The clutch chuck 4 adopts a jaw clutch design, and can automatically separate from the screw rod 1 when the rotating torque of the screw rod is larger than the design torque, so that the thread of the valve sleeve is protected from being damaged. The clutch chuck is disengaged from the screw 1 when the force pulling outward is greater than the spring force of the small spring 6.
The boss on the screw sleeve 3 is embedded in the clamping groove at the front section of the outer sleeve 2, and the screw rod 1 cannot drive the screw sleeve 3 to rotate when rotating, so that the thread of the valve sleeve can be automatically screwed into the screw sleeve.
The torque of the clutch chuck disengagement is adjusted by rotation of the nut 5.
The material of the clutch chuck 4 is 9Cr18 Mo.
The clearance between the polished rod section of the screw rod 1 and the threaded sleeve 3 is not less than 0.2 mm. Therefore, the screw rod is allowed to be slightly dislocated with the central line of the disassembled valve sleeve when rotating, and the adaptability is stronger.
The thrust bearing 7 prevents the small spring 6 from rubbing against the nut 5 before the small spring 6 and the nut 5 increase in elastic force when the small spring 6 is compressed. The large spring 8 can provide a forward force for the screw sleeve to ensure that the valve sleeve can smoothly enter the unconnected two-section threads
When the manual work is carried out: the valve sleeve to be disassembled is screwed out by rotating the screw sleeve 1 anticlockwise to drive the valve sleeve 4 to rotate, the thread part is exposed, the screw sleeve 2 is rotated clockwise to drive the valve sleeve 3 to rotate, threads on a part are selected into the screw sleeve 3, the outer sleeve 2 is jacked to a part where the part is disassembled after the screw sleeve 3 finishes the stroke of the polish rod section on the screw rod, the screw sleeve 3 of the screw rod 1 is rotated anticlockwise to be separated from the clutch chuck 4, and the screw sleeve 3 of the screw rod 1 is rotated continuously to drive the valve sleeve to move linearly outwards so as to disassemble the valve sleeve.
When the electric work is performed: the screw 1 is rotated anticlockwise by the hand-held outer sleeve 2 to drive the clutch chuck 4 to screw out of threads on the top of the valve sleeve and simultaneously enter the screw sleeve 3, the outer sleeve 2 moves forwards to prop against the end face of a shell where the valve sleeve is located, after the screw sleeve 3 finishes the stroke of a polished rod section of the screw 1, the screw 1 is separated from the clutch chuck 4, the outer sleeve 2 and the shell generate interaction force, and the screw 1 drives the screw sleeve 3 to move outwards in a straight line, so that the valve sleeve is disassembled.
