Abstract
The utility model relates to an oil pumping centralizer applied to the mechanical oil production of the oil field sucker rod pump, providing an oil pumping centralizer with big fluid open area, small oil stream resistance, even core stress, synchronous revolution of the up and down valves, no attrition of the sealing part of the valve, moving freely of the valve, long service time, good closure of the valve and good effect of oil pumping, centralizing and paraffin cutting. The utility model comprises a round bar body with connecting fittings in both ends, which is characterized in that a lower revolving valve and an upper revolving valve which has spiral flutes are sleeved with the middle of the round bar body; the inner groove arranged in the lower revolving valve is sleeved with the baffle platform of the round bar body; an upper convex plate is arranged on the round bar body which is arranged at the superior end of the upper revolving valve and the lower end surface of the upper revolving valve. The lower revolving valve and the upper revolving valve are injecting molded on the round bar body. The utility model can be widely applied to the fields such as exploiting the fluid from well.
Description
Technical field
The utility model relates to a kind of oil pumping centralizer that is used for oil field sucker rod pump mechanical oil recovery.It belongs to the field of production fluid from well.
Background technology
The present common oil pumping centralizer function singleness of using, area of passage is little in oil pipe, and the convection cell resistance is big, and body of rod cross sectional shape is square, flexible.There is and set upright valve body and on the body of rod, can't rotate, cause eccentric wear, the life-span short to topic.The product that has has only single valve body, does valve seat with the body of rod.It is big to there is the wearing and tearing of sealing position, easily leaks, and the life-span is short, the problem of weak effect.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of fluid area of passage big, oil flow resistance is little, and the body of rod is stressed evenly, the sealing position of valve does not have wearing and tearing, and valve body rotates flexibly, and the life-span is long, the closed performance of valve is good, the oil pumping centralizer that pump, set upright, the paraffin cutting effect is all good.
Technical problem of the present utility model is solved by following technical scheme: a kind of oil pumping centralizer that is used for oil field sucker rod pump mechanical oil recovery, the round bar body that comprises two ends band connector, it is characterized in that round bar body middle part is with rotary valve and last rotary valve under the band spiral fluted, inside groove on the following rotary valve is enclosed within on the shelves platform of round bar body, and the round bar body of last rotary valve upper end is provided with convex platform.
Above-mentioned oil pumping centralizer, there is the guide-localization groove lower surface of following rotary valve upper surface and last rotary valve.
Above-mentioned oil pumping centralizer, being positioned at down, the round bar body of rotary valve lower end is provided with lower convex platform.
Compared with prior art, the beneficial effects of the utility model are: increased area of passage, improve set upright, paraffin cutting and oil increasing effect, avoided the mill of sealing contact surface between eccentric wear between rotary valve and oil pipe and two valve bodies to fall from the sky or outer space, reached raise the efficiency, the purpose of life-saving and reduction expense.
Description of drawings
Accompanying drawing is the structural representation that the utility model is being opened the valve body state.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail: the oil pumping centralizer is the round bar body 1 by middle part band shelves platform 9, and top is provided with convex platform 5, be provided with internal thread 11 in the upper end of convex platform 5, round bar body 1 bottom is provided with external screw thread 6, round bar body 1 middle part is with the following rotary valve 2 and the last rotary valve 4 of band helicla flute 10, inside groove 8 on the following rotary valve 2 is enclosed within on the shelves platform 9 of round bar body 1, the lower surface of following rotary valve 2 upper surfaces and last rotary valve 4 is provided with guide-localization groove 3, and being positioned at down, the round bar body 1 of rotary valve 2 lower ends is provided with lower convex platform 7.Following rotary valve 2 is axially fixed in round bar body 1 bottom, can rotate freely around round bar body 1, can not move up and down at round bar body 1; Last rotary valve 4 is installed in down rotary valve 2 tops, and it can also can move up and down at round bar body 1 around the rotation of round bar body simultaneously.In last rotary valve 4 lower surfaces and following rotary valve 2 upper surfaces guide-localization groove 3 is arranged all.When it is installed in the producing well, with sucker rod when descending, following rotary valve 2 rotates in round bar body 1 bottom because of not moving up and down still at round bar body 1, last rotary valve 4 is under the effect of oil pipe inner fluid, be pulled to round bar body 1 top and rotate freely, and separate with following rotary valve 2, valve is opened, and fluid passes through in helicla flute 10 and the valve opened smoothly.When sucker rod is up, last rotary valve 4 the pipe inner fluid effect under descending, and under the effect of guide-localization groove 3 with following rotary valve 2 tight connectings, formation valve closed form.Fluid in the oil pipe along with sucker rod up and by on take out, finish an oil pumping process.Round bar body 1 of the present utility model is a cylinder, upper and lower rotary valve 2,4 all can rotate freely around round bar body 1, upper and lower rotary valve 2,4 profiles all have helicla flute 10, circulation area is big, two rotary valves 2,4 are no matter when descending separation, or during up being integrated, all can rotate freely, play and set upright preferably and the paraffin cutting effect around round bar body 1.When sucker rod was up, upper and lower rotary valve 2,4 was integrated under the effect of guide-localization groove 3, and when forming closure, two rotary valves 2,4 rotate synchronously, and the contact seal position of valve is wearing and tearing not, have improved efficient, have prolonged application life.Last rotary valve 4 and following rotary valve 2, injection mo(u)lding is on round bar body 1.
The course of work of the present utility model is as follows: the centralizer of will pumping in producing well is installed between two sucker rods (can install dozens of according to well adapter ring situation), on when sucker rod is descending under the effect of the fluid of rotary valve 4 in oil pipe, go upward to convex platform 5 places of round bar body 1, two valve bodies separate, rotate freely separately, valve is opened, and fluid passes through in helicla flute 10 and the valve opened smoothly.When sucker rod is up, descending under the fluid effect of last rotary valve 4 in pipe, and under 3 guiding of guide-localization groove, insert in the guide-localization groove 3 of rotary valve 2, two rotary valves, 2,4 integrators, rotation synchronously, valve cuts out, oil channel sealing.Take out in up along with sucker rod, the fluid in the oil pipe together, finish an oil pumping process.Dozens of oil pumping centralizer is installed in a bite well, is made in the well to have become the dozens of oil well pump, along with oil pumper moves back and forth by an original oil well pump, fluid is constantly promoted respectively, so improved greatly set upright, paraffin cutting and increase the effect of oil, prolonged the life-span, reduced expense.
