Detailed Description
As shown in fig. 1, a high temperature hydraulic cylinder formula plugging device, including connecting seat 1, two-way hydraulic cylinder 2 and locating lever 5, connecting seat 1 and locating lever 5 set up respectively at two-way hydraulic cylinder 2 top and bottom, two-way hydraulic cylinder 2's left piston rod 21 is connected the fastening with sealing ring 3 and is in the same place, two-way hydraulic cylinder 2's right piston rod 22 is connected the fastening with sealing ring 4 and is in the same place, locating lever 5 bottom has the location centre bore, two-way hydraulic cylinder 2 sets up oil return 23, oil inlet 24 and oil return 25, hydraulic oil passes through inside oil inlet 24 gets into two-way hydraulic cylinder, left piston rod 21 and right piston rod 22 drive the sealing ring of corresponding one side respectively to extend to the outside, hydraulic oil gets into inside two-way hydraulic cylinder through two oil return, left piston rod and right piston rod drive the sealing ring of corresponding one side respectively and retract to the inside. The left oil return port and the right oil return port are connected in parallel.
The plugging process of the utility model is as shown in figure 2: welding a sealing sleeve 6 on a pipeline, installing a packing sealing ring 8 in a sealing groove of the sealing sleeve after welding, installing and welding a plugging pipe fitting 7, firstly performing tapping operation, after the tapping operation is completed, performing plugging operation, feeding a high-temperature hydraulic oil cylinder type plugging device into a pipeline tapping position by a plugging device, inserting a central rod 9 at the bottom of the plugging pipe fitting 7 into a positioning hole of a positioning rod 5, enabling hydraulic oil pressure to enter the inside of a hydraulic oil cylinder through an oil inlet 24 through an oil inlet pipe 10, driving a sealing ring 3 and a sealing ring 4 to extend outwards by a left piston rod 21 and a right piston rod 22 until the sealing ring 3 is attached to the packing sealing ring 8, and completing plugging. When the blockage is removed, hydraulic oil pressure is required to enter the hydraulic oil cylinder through the oil return port 23 and the oil return port 25, and the left piston rod 21 and the right piston rod 22 drive the sealing ring 3 and the sealing ring 4 to contract inwards.
