Embodiment
Referring to Fig. 1-Fig. 7, the big flow passage oil-well pump of a kind of anti-plugging of the present invention comprises pump barrel 10, plunger piston assembly A and standing valve 11, and plunger piston assembly A is slidingly mounted in the pump barrel 10, and pump barrel 10 internal fixation below this plunger piston assembly A install and fix valve 11.
Described plunger piston assembly A comprises upper travelling valve 1, plunger 3, lower travelling valve 2 and joint 7, and upper travelling valve 1 is through the joint 7 coaxial upper ends that are connected plunger 3, the lower travelling valve 2 coaxial lower ends that are connected plunger 3.
The structure of described standing valve 11, upper travelling valve 1 and lower travelling valve 2 is identical, and (referring to Fig. 2-Fig. 4), include valve bonnet 4, valve ball 5 and valve seat 6, valve seat 6 is installed in the bottom in the valve bonnet 4 of tubular, and valve ball 5 is located at the top of valve seat 6.The middle part sealing of the upper end of described valve bonnet 4; Around the middle part, be provided with a plurality of liquid outlet openings 8 that are uniformly distributed along the circumference; The inner peripheral surface of the valve bonnet 4 between this liquid outlet opening 8 lower ends to top of valve seat 6 is provided with the corresponding axial notch 12 of a plurality of and this liquid outlet opening 8, between adjacent axial notch 12, forms a plurality of righting ribs 9.
Described joint 7 is cylindric, and its two ends are equipped with outside thread 71, is connected with the internal thread of valve bonnet 4 lower ends of upper travelling valve 1 and the internal thread of plunger 3 upper ends respectively.
The internal thread of said plunger 3 lower ends is connected with the outside thread on the valve bonnet top of said lower travelling valve 2.
The present invention in use, the top of its upper travelling valve 1 is connected with sucker rod through link 13, the lower end of the valve bonnet 4 of the standing valve 11 of bottom is fixed through link 14 and pump barrel 10, is conventional mounting type.
Core technology of the present invention is the design of the valve bonnet 4 of its standing valve 11, upper travelling valve 1 and lower travelling valve 2; Liquid outlet opening 8 is located at the edge; And adopt middle part sealing (like Fig. 3 and shown in Figure 6), in valve bonnet 4 cavitys, adopt 9 designs (like Fig. 4 and shown in Figure 7) of three four righting ribs.Its effect has following 4 points:
1, the advantage of 2 pairs of traveling valve designs of upper travelling valve 1 and lower travelling valve is to eliminate the little problem of traveling valve structure area of passage traditionally, has guaranteed that the runner of oil well pump does not dam.
The area of three (or four) liquid outlet openings 82, being opened, valve ball 5 area of passage when valve bonnet 4 inner chambers are middle and the area unanimity of valve ball seat 6 inlet openings have realized the big runner design of traveling valve.
3, upper travelling valve 1 inner chamber adopts three (or four) righting ribs 9 to play the position-limiting action to valve ball 5, guarantees that valve ball 5 along (axially) straight line motion, does not have radial motion basically, has accelerated the falling closing velocity.
4, three arc liquid outlet openings 8 (as shown in Figure 3) of opening of edge are driveed at the different shape liquid outlet opening at center with tradition and are compared, and have avoided because of long-term bump plugging fluid circulation road or block the problem of valve ball 5.
Working principle of the present invention is:
1, when plunger piston assembly A is descending, the liquid between compression plunger assembly A and the standing valve 11 under the effect of fluid pressure, opens upper travelling valve 1 and lower travelling valve 2, and 11 of standing valves cut out.The valve ball 5 of upper travelling valve 1 and lower travelling valve 2 up and in succession bump terminate in the lower end closed plane of the liquid outlet opening 8 of valve bonnet 4, effectively stopped the stifled problem of card.When plunger piston assembly A came downwards to lower dead centre, the liquid of bottom was upwards through reaching in the pump barrel 10 above the plunger piston assembly A behind upper travelling valve in the plunger piston assembly A 1 and the lower travelling valve 2 in the pump barrel 10.
2, when plunger piston assembly A is up, under the action of gravity of the action of gravity of liquid and valve ball self, upper travelling valve 1 is closed with lower travelling valve 2; Simultaneously between plunger piston assembly A and standing valve 11, form negative pressure, under this action of negative pressure, standing valve 11 is opened, and the valve ball 5 of standing valve 11 clashes into and terminate in the lower end closed plane of the liquid outlet opening 8 of valve bonnet 4, has effectively stopped the stifled problem of card.Go upward to upper dead center, the liquid in pump barrel 10 inner plunger assembly A tops and the plunger is by upwards lifting, and liquid is sucked into above the standing valve 11 of pump barrel 10 bottoms in the pit shaft lower end.Accomplish a working procedure.Repeat above process, realize the underground liquid that contains is extracted on the ground continuously.
Because oil well pump needs continuously for a long time in underground deep layer work; It will have serviceability the oil well production environmental requirement; The valve vice president becomes to face two test, and the one, working in reciprocating mode all will be born bigger impact force under high-pressure sealed situation each time, and the 2nd, the corrosivity of fluid.Therefore, structural simple and durable is primary, also will guarantee pump efficiency simultaneously.Experiment shows that the present invention makes oil well pump prolong 30.1% disposable working life, makes pump efficiency improve 2.3 percentage points, has further improved the economic benefit of oil field development.
