Abstract
An eccentric buckle-changing joint is applied to the oil field well repairing construction. Is characterized in that: the outer wall of one end of the large-diameter pipe is provided with threads, the other end of the large-diameter pipe is welded with a blocking plate, the outer diameter of the blocking plate is the same as the diameter of an inner hole of the large-diameter pipe, and the blocking plate is provided with an eccentric through hole; a small-diameter pipe is vertically welded on the upper plane of the blocking plate, and the central line of the small-diameter pipe and the central line of the eccentric hole of the blocking plate are the same straight line; the outer wall of the other end of the small-diameter pipe is provided with threads. The effect is as follows: the defects that the drainage speed is low due to small water level fall and the speed is low due to the fact that pipe tongs must be used for dismounting are overcome, the labor intensity of workers is reduced, and the construction speed is increased.
Description
Technical field
The utility model relates to technical field, and is particularly a kind of.Petroleum system engineer equipment and field of tool, the eccentric variable buckle joint of special use when particularly a kind of underground work actuating oil-pumping unit is constructed.
Background technology
At present, China Patent Publication No.: CN202000914U provides a kind of " cylinder type operating platform for sucker rod ".It is the isolated plant when being applied to the on-the-spot actuating oil-pumping unit of underground work, realize righting, sealing, de-waxing, drainage required in the rod job, laid the integration of a plurality of functions such as paraffin cutting oil-scraping device, rapid-assembling/disassembling, improve speed of application, improved employee's operating environment.Cylindrical shell at " cylinder type operating platform for sucker rod " has wax discharging port, and it is the short tube of 156 millimeters of external diameters, in be 51/2 inch casing coupling internal thread, discharge the things such as wax, oil, damage nylon wax wiper when being used for sucker rod; Also can connect hose by variable buckle, be extruded liquid to the backflow of oil jacket annular space in the pipe when being used for behind the pipe string pressure test lower sucker rod.The variable buckle of using at present is the concentric variable buckle of large path, and the shortcoming that field practice appears is that the little earial drainage speed that causes of the height of water is slow, and dismounting must use pipe wrench to cause speed slow.
The utility model content
The purpose of this utility model is: a kind of eccentric variable buckle joint is provided, the eccentric variable buckle of special use when cooperating cylinder type operating platform for sucker rod to carry out the actuating oil-pumping unit construction in the underground work, eliminate the height of water little cause earial drainage speed slow, must use pipe wrench to cause the slow-footed shortcoming of dismounting, reduce staff labor intensity, improve speed of application.
The technical solution adopted in the utility model is: eccentric variable buckle joint, comprise narrow tube, large diameter pipe and closure plate, it is characterized in that: on the end outer wall of large diameter pipe screw thread is arranged, the other end at large diameter pipe is welded with closure plate, the external diameter of closure plate is identical with the large diameter pipe diameter of bore, at closure plate eccentric through-hole is arranged; Upper plane at closure plate is vertically welded with narrow tube, and the eccentric orfice center line of the center line of narrow tube and closure plate is the same straight line; Other end outer wall at narrow tube has screw thread.
For handled easily, be vertically welded with the cylindricality handle on the upper plane of closure plate.The quantity of described cylindricality handle is 1 or 2.
The external screw thread of narrow tube can connect the hose external screw thread oil internal thread in the ninth of the ten Heavenly Stems, and the external screw thread of large diameter pipe is to cooperate with the wax discharging port of " cylinder type operating platform for sucker rod ", and the external diameter of large diameter pipe is 139.7 millimeters.
The beneficial effects of the utility model: the eccentric variable buckle joint of the utility model, the eccentric variable buckle of special use when cooperating cylinder type operating platform for sucker rod to carry out the actuating oil-pumping unit construction in the underground work, eliminate the height of water little cause earial drainage speed slow, must use pipe wrench to cause the slow-footed shortcoming of dismounting, reduce staff labor intensity, improve speed of application.
Description of drawings
Fig. 1 is the eccentric variable buckle joint design of the utility model generalized section.
Among the figure, 1-narrow tube, 2-large diameter pipe, 3-closure plate, 4-cylindricality handle.
The specific embodiment
Embodiment 1: take an eccentric variable buckle joint as example, the utility model is described in further detail.
Consult Fig. 1.The eccentric variable buckle joint of the utility model comprises narrow tube 1, large diameter pipe 2 and closure plate 3.The external diameter of large diameter pipe 2 is 139.7 millimeters, 124 millimeters of internal diameters, 100 millimeters of length.On the one end outer wall of large diameter pipe 2 screw thread is arranged.The other end at large diameter pipe 2 is welded with closure plate 3,124 millimeters of external diameters of closure plate 3, thick 10 millimeters.At closure plate 3 eccentric through-hole is arranged; Upper plane at closure plate 3 is vertically welded with narrow tube 1,50 millimeters of the length of narrow tube 1,73 millimeters of external diameters.The eccentric orfice center line of the center line of narrow tube 1 and closure plate 3 is the same straight line; Other end outer wall at narrow tube 1 has screw thread.Be vertically welded with a round shank 4 on the upper plane of closure plate 3.The diameter 20mm of cylindricality handle 4, length 45mm.Cylindricality handle 4 can be done hand-screw handle and the crowbar strong point, in order to reduce labour intensity.
Sketch the use procedure of eccentric variable buckle, help to understand the utility model.When using cylinder type operating platform for sucker rod to carry out behind the pipe string pressure test lower sucker rod construction, manual large diameter pipe 2 screwed into operating desk wax discharging port internal thread, crowbar or pipe wrench screw and make narrow tube 1 to be in minimum point, narrow tube 1 external screw thread connects first external screw thread or internal thread oil head in the ninth of the ten Heavenly Stems, the internal thread of the hose that connect to cooperate again or external screw thread oil ninth of the ten Heavenly Stems, hose is the splicing sleeve gate again.Fashionable under the sucker rod, the same volume pressure testing that the body of rod is extruded uses liquid by the oil jacket annular space of the narrow tube 1 quick backflow pit shaft of lowest order.
