Abstract
The utility model discloses a device for removing an oil extracting valve under pressure, which is used for an oil transmission pipeline, comprises an impelling rod (1), a sealing ring (2), a blowout preventing tube (3) and a die tap (5). The device is characterized in that a cylinder structure is adopted, inner and outer screw threads are arranged at the lower part of the blowout preventing tube (3), the lower part of the impelling rod (1) is provided with outer screw threads which are matched with the inner screw threads of the blowout preventing tube (3), an annular slot is arranged at the upper part of the outer screw threads of the impelling rod (1), the sealing ring (2) is arranged inside the annular slot, the bottom of the impelling rod (1) is provided with a square blind hole which is connected with a square wedge on the top of the die tap (5) in a plugging way, and a tapered die button (8) is arranged at the lower part of the die tap (5). The device removing the oil extracting valve under pressure can implement operation and construction under pressure, does not need production halt of the oil transmission pipeline, avoids various losses caused by halting production for removing the oil extracting device, quickly eliminates the oil extracting valve, saves the loss of crude oil, and has remarkable economic benefits.
Description
One, technical field
The utility model relates to a kind of preventing from the tool technique of petroleum pipeline stolen, particularly is that a kind of band is pressed dismounting stolen valving.
Two, background technique
Lawless person's stolen method on petroleum pipeline is a lot of at present, wherein a kind of is that valve is welded on the clamp, valve covers the default hole of clamp, again clamp is fixed on the petroleum pipeline, opens valve, drilled valve with steel and on petroleum pipeline, beat stolen hole (generally being the band pressure punching of taking a risk), take out the steel brill after having beaten the stolen hole, throttle down connects sebific duct in the valve upper end, and opening valve when needing stolen at any time just can stolen.When the post workman finds to adopt this method stolen, owing in the pipeline band hydraulic fluid is arranged, can not arbitrarily remove, remove valve and shutoff stolen hole and generally all want the interior crude oil of blow-down pipe, remove valve then, shut the stolen hole with electrogas welding again.This nothing is pressed method for dismounting owing to need the interior crude oil of blow-down pipe, and petroleum pipeline will stop production and put pressure, influences normal oil transportation production, and the engineering time is long, and economic loss is serious.
Three, summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of band of designing is pressed and removed the stolen valving.
The utility model comprises: push rod, seal ring, lubricator, die nipple; It is a cylindrical structure, in the lubricator bottom is provided with, outside thread, the outside thread of lubricator bottom is connected with stolen valve internal thread, the push rod bottom is provided with outside thread and matches with the internal thread of lubricator, the externally threaded top of push rod is provided with circular groove, seal ring is housed in the circular groove, with the gap between sealing lubricator and the push rod, the bottom of push rod is provided with square blind hole and is plugged on the square contract piece at die nipple top, push rod and die nipple can not rotate after pegging graft relatively, can transmitting torque, the bottom of die nipple is provided with the taper pin thread, the taper pin thread can be on the petroleum pipeline stolen mouth thread making.
The beneficial effects of the utility model are: can Operating Pressure construct, petroleum pipeline does not need to stop production, and having avoided stops production removes the various losses that the stolen device causes, can eliminate the stolen valve fast, reduces crude oil loss, has remarkable economic efficiency.
Four, description of drawings
Accompanying drawing is the utility model The field structural representation.
In the accompanying drawing, the 1-push rod, the 2-seal ring, the 3-lubricator, 4-stolen valve, the 5-die nipple, the 6-clamp, the 7-petroleum pipeline, 8-taper pin thread, 9-presets the hole, 10-stolen hole.
Five, embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
Band is pressed and is removed the stolen valving, comprising: push rod 1, seal ring 2, lubricator 3, die nipple 5; It is a cylindrical structure, lubricator 3 bottoms are provided with internal and external screw thread, push rod 1 bottom is provided with outside thread and matches with the internal thread of lubricator 3, the externally threaded top of push rod 1 is provided with circular groove, seal ring 2 is housed in the circular groove, the bottom of push rod 1 is provided with square blind hole and is plugged on the square contract piece at die nipple 5 tops, and the bottom of die nipple 5 is provided with taper pin thread 8.
Operating method:
At first, stolen valve 4 is in closed condition to press the outside thread of lubricator 3 bottoms of removing the stolen valving to be connected at this moment with stolen valve 4 internal threads on the band that assembles, and die nipple 5 front ends are on the valve plate of stolen valve 4; Secondly, open the valve plate of stolen valve 4, under seal ring 2 effects, the high pressure oil stream of petroleum pipeline 7 can not spray, rotation push rod 1, under the box thread effect of male thread on the push rod 1 and lubricator 3 bottoms, push rod 1 descending and also walking downwards and rotation of drive die nipple 5, taper pin thread 8 contacts with stolen hole 10, and taper pin thread 8 is thread making on petroleum pipeline 7, die nipple 5 and petroleum pipeline 7 are linked together, stop up stolen hole 10; The 3rd, remove the connecting bolt on the clamp 6, press dismounting stolen valving to take away together on clamp 6, stolen valve 4 and band, stay die nipple 5, die nipple 5 and petroleum pipeline 7 are welded together, the sawed-off exposed parts of die nipple 5 on petroleum pipeline 7 of making, thus the band pressure is finished dismounting stolen valve 4; The 4th, will be with to press and remove the maintenance of stolen valving wiped clean, in order to using again.
Claims (1)
1. one kind is used for oil transport pipeline band pressure dismounting stolen valving, comprising: push rod (1), seal ring (2), lubricator (3), die nipple (5); It is characterized in that: band is pressed and removed the stolen valving is cylindrical structure, lubricator (3) bottom is provided with internal and external screw thread, push rod (1) bottom is provided with outside thread and matches with the internal thread of lubricator (3), the externally threaded top of push rod (1) is provided with circular groove, seal ring (2) is housed in the circular groove, the bottom of push rod (1) is provided with square blind hole and is plugged on the square contract piece at die nipple (5) top, and the bottom of die nipple (5) is provided with taper pin thread (8).
