Abstract
The utility model discloses a belt pressure leaking stoppage device of an oil field oil transportation pipeline. The belt pressure leaking stoppage device of the oil field oil transportation pipeline comprises a top pressure sleeve pipe, an ejector rod, a sealing cavity connection body and a plug. The ejector rod penetrates into the top pressure sleeve pipe, a sealing ring is assembled between the top pressure sleeve pipe and the ejector rod, the lower end of the ejector rod is connected with the plug, outer threads are arranged on the outer surface of the top pressure sleeve pipe, the sealing cavity connection body is installed at the lower end of the top pressure sleeve pipe, and a drainage valve is installed on the sealing cavity connection body. A supporting transverse rod is arranged at the upper end of the top pressure sleeve pipe, and supporting vertical rods are arranged at the two ends of the supporting transverse rod. The upper end of the sealing cavity connection body is further connected with a buffer sealing cavity. When an oil stealing device is disassembled, the belt pressure leaking stoppage device achieves the rapid leaking stoppage aim under the situation of non-production-stoppage pressure relief, reduces crude oil losses, prevents the oil transportation pipeline condensing accidents caused by long-time production stoppage in winter from happening, and has remarkable economic benefits.
Description
Technical field
The utility model relates to a kind of oilfield oil pipeline maintenance leak stoppage tool, especially a kind of petroleum pipeline band pressure leak stopping device.
Background technique
At present, mounted valve after the stolen molecule punches on petroleum pipeline is stolen crude oil by control valve.When removing these stolen valves, be generally that oil well is stopped production, remove stolen valve, then perforations adding after blow-down pipe pressure.Affect pipeline owing to stopping production and carry, give the crude oil production economic loss.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of and do not need to close oil well, can reduce the oilfield oil pipeline tape-pressure leakage clogging device of crude oil loss.
The utility model is taked following technical measures: a kind of oilfield oil pipeline tape-pressure leakage clogging device, comprise top gland pipe, push rod, Seal cage connecting body, plug, described push rod penetrates top gland pipe, be equipped with seal ring between top gland pipe and push rod, the push rod lower end is connected with plug, top gland tube outer surface is provided with outside thread, and the lower end is equipped with the Seal cage connecting body, on the Seal cage connecting body, drain valve is installed.
Gland pipe upper end, described top is provided with support rail, and support rail two ends are provided with vertical supporting rod.
Described Seal cage connecting body upper end also is connected with the cushion seal cavity.
The beneficial effects of the utility model are, when removing the stolen device, solved the purpose that realizes instantaneous leaking-stopping in the situation of the release that do not stop production, reduce the crude oil loss, also avoid the generation of the solidifying event of running affairs of petroleum pipeline that winter, long-time stopping production brought, had significant economic benefit.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of oilfield oil pipeline tape-pressure leakage clogging device, comprise top gland pipe 3, push rod 5, Seal cage connecting body 1, plug 8, top gland pipe 3 outer surfaces are processed with outside thread, described push rod 5 penetrates top gland pipe 3, is equipped with seal ring 7 between top gland pipe 3 and push rod 5, and push rod 5 lower ends are connected with plug 8, gland pipe 3 lower ends, top are equipped with Seal cage connecting body 1, and drain valve 9 is installed on Seal cage connecting body 1.Described Seal cage connecting body 1 upper end also is connected with cushion seal cavity 2.Gland pipe 3 upper ends, described top are connected with support rail 4 by screw thread, and support rail 4 two ends are provided with vertical supporting rod 6.
working procedure of the present utility model is: at first select suitable taper plug 8, be installed to the lower end of push rod 5, Seal cage connecting body 1 is installed on the stolen ball valve, cushion seal cavity 2 is connected with the Seal cage connecting body closely connects, rotary support cross bar 4 is adjusted the working position, vertical supporting rod 6 lower ends are fixed on petroleum pipeline, open after the stolen valve rotation top gland pipe 3 and head on simultaneously the taper plug 8 descending stolen hole of touching together with push rod 5, taper plug 8 is embedded into firmly in the stolen hole by apply external force at push rod 5 tail ends, thereby fitting tightly, formation stops up the stolen hole.The drain valve 9 of opening on Seal cage connecting body 1 is let out most Seal cage connecting body 1 and interior overbottom pressure and the remaining liquid of cushion seal cavity 2, after confirming with no pressure, remove the stolen valve, manifest taper plug 8, with electric welding, taper plug 8 is welded on petroleum pipeline, completes the oil line pressured plugging operation.
