Description
Technical field
The utility model relates to a kind of oil transport pipeline blocking device, particularly a kind ofly implements not have the oil transport pipeline that leaks shutoff at oil transport pipeline under stop status and steals pore area and press plugging device.
Background technique
Oil transport pipeline is the important means of oil transportation, and it relates to economic life line of the country safely.At present, the lawless person is commonplace in the phenomenon that oil transport pipeline punching, mounting ball valve carry out stolen, can repeat constantly to steal oil by ball valve.When carrying out shutoff for this type of robber hole on the oil transport pipeline, because the pressure of crude oil is too big in the pipeline, so when construction, must to will just can carry out shutoff after ducted crude oil shutdown, the pressure release earlier, the recovery required time of oil transportation is long from the pipe plugging to the pipeline, shutoff mode working efficiency such for long distance oil pipeline is low, and it is very inconvenient to construct, and the stopping transportation of oil transport pipeline is huge to the loss that enterprise causes.
The scheme in shutoff oil transport pipeline robber hole mainly contains at present: the cover cap welds and embeds these two kinds of methods of timber wedge on the ball valve in stealing the hole; Preceding a kind of method forms corrosion and not attractive in appearance easily in the protruding part, the chock that embeds pipeline in a kind of method in back can stop passing through of the interior rotating wash bowl of pipeline, more than two kinds of methods all need pipeline shutdown, implement after the pressure release, stopping transportation causes economic loss huge to oil play.
The model utility content
At the deficiencies in the prior art part, the utility model will provide a kind of oil delivering pipe road to steal pore area and press plugging device, this oil transport pipeline is stolen pore area and is pressed plugging device not carry out shutoff to stealing the hole under the prerequisite of stopping transportation at oil transport pipeline, and the leakage of crude oil can not appear in omnidistance sealing height when shutoff.
The technological scheme that its technical problem that solves the utility model adopts is:

Working principle of the present utility model and working procedure are:
The lawless person is welded on short tube 7 on the oil transport pipeline 13 when stolen, and at short tube 7 dress ball valves 6, at ball valve 6 perforating device being installed then punches, oil is stolen for a long time by at ball valve 6 flexible pipe being installed in the punching back, and the main pin of this plugging device carries out the behavior of long-term stolen at oil transport pipeline punching mounted valve.
Because all be the drill bit of employing standard during stolen molecule drilling hole of oil stolen, in order to satisfy the robber hole in the multiple aperture of shutoff, described rubber shutoff plug 2 is made the rubber plug 20 of multiple diameter in advance according to the bit diameter difference.
At first, to lead tube 5 is installed on the ball valve 6, fixed muffle 4 is installed on the main tube 5, bistrique 8 is installed in the body cavity of calibrating axle 12 lower ends, and be screwed, pointer 3 is installed on the punch block 2, with punch block 2 be installed to calibrate the axle 12 on, lever 1 is inserted the through hole of calibrating axle 12 upper ends, the axle 12 of calibrating that installs bistrique 8 is inserted from fixed muffle 4 upper ends, after the threaded engagement of calibrating the axle screw thread of 12 outer walls and fixed muffle 4 inwalls, drive by lever 1 and calibrate axle 12 downward feedings, can indicate bistrique 8 to enter the degree of depth of main tube 5 by pointer 3, when bistrique 8 enters into ball valve 6 and Shang Weiding to the valve of ball valve 6, spanner by ball valve 6 is with valve open, calibrate axle 12 by lever 1 drive and rotate the downward feeding of continuation, up to the robber hole that bistrique 8 pushes up on the oil transport pipeline 13, lever 1 feeding, withdraw from three times, make that stealing hole wall grinds off the dry paint on the bistrique 8, will calibrate axle 12 and screw out, by pointer 3 indications, just withdrawed from the valve of ball valve 6 when bistrique 8, with valve closing, screw out and calibrate axle 12, the cleaning oil pollution on the bistrique 8 is clean, by the polishing scratch on the bistrique 8, measure the diameter of stealing the hole with the vernier calliper side.
Again, shutoff screw 16 is inserted from rubber plug 20 lower ends, shutoff nut 17 screws off and compresses rubber plug 20 from shutoff screw 16 upper ends, shutoff nut 17 is fixed in the cavity of shutoff axle 15 lower ends, the annular of sleeve pipe 14 lower ends is told groove to be inserted in the annular groove in the rubber plug 20 and chucking, this moment, the through hole of sleeve pipe 14 and shutoff axle 15 upper ends alignd, by lever 18 both are fixed, mounted sleeve pipe 14 is inserted from fixed muffle 4 upper ends, rotating lever 18 makes sleeve pipe 14 feeding downwards under the internal thread interlock of fixed muffle 4, indication by pointer 3, before entering into ball valve 6 and do not push up valve, rubber plug 20 opens ball valve 6, make sleeve pipe 14 continue downward feeding by lever 18, hold out against feeding downwards on the oil transport pipeline 13 up to rubber plug 20, open Decompression valves 9 and release pressure inside, when being zero, hydralic pressure gauge 10 pressure close Decompression valves 9, if the registration of hydralic pressure gauge 10 remains 0 expression and steals the hole by jam-pack, if hydralic pressure gauge 10 has registration, repeat above operation, lever 18 is taken away, rotating lever 19, driving shutoff axle 15 rotates, shutoff axle 15 drives shutoff nut 17 and rotates, thereby make rubber plug 20 expand with carrying on the shutoff screw 16, thereby will steal the complete shutoff in hole, cut off and plugging device is pulled down from short tube 7, have only shutoff nut 17 on transport pipe 13 surfaces, shutoff screw 16, rubber plug 20 this moment.
At last, shutoff cover cap 21 is covered rubber plug 20 and tightens shutoff nut 17, and shutoff cover cap 21 ground are cambered surface, are close to oil transport pipeline 13, shutoff cover cap 21 is welded on oil transport pipeline 13 surfaces, and realization is welded to stealing the shutoff in hole in shutoff cover cap 21 and shutoff nut 17 contacting points.
