The utility model content
For overcoming the defective that above-mentioned prior art exists, the technical problem that the utility model will solve provides a kind of shunting ball-and-seat, improves the problem of traditional electric submersible pump ball-and-seat leakage, increases oil well output, prolongs the pump detection period of electric pump well; The phenomenon that bleeder can't normally be opened when solving the oil well operation has shortened the activity duration; Impeller when solving the electric pump shutdown in the pump increases oil well output to the influence of electric pump well blowing.
For solving the problems of the technologies described above; The shunting ball-and-seat of the utility model is threaded each other and is formed by lower contact 1, valve body 3, top connection 21; Wherein, above-mentioned valve body inside is made up of guide rod 5, valve seat 6, spool 8, little spring 9, little spring pad 10, spring 12, piston 13, strainer 14, piston guide cap 16 and sealing shroud 19; Above-mentioned guide rod 5 is positioned at spool 8 inside; Pin 4 passes spool 8 bottoms and guide rod 5 bottom fixed spools 8 and guide rods 5, and this spool 8 inserts in valve seats 6, and little spring 9 is positioned at the upper end of spool 8 inside and around guide rod 5; Be mounted with little spring pad 10 above the little spring 9; Piston 13 inserts in the spring 12, and valve seat 6 is threaded with piston 13, and strainer 14 is installed in the hole on the piston 13; Piston guide cap 16 is installed on the piston 13, and sealing shroud 19 is in valve body 3 inside.
Six screws, 2 fastening its are threaded with lower contact 1, top connection 21 in installing on the above-mentioned valve body 3.
7 sealings of O circle are installed between above-mentioned guide rod 5 and the spool 8; Piston 13 upper and lowers respectively and O circle sealing is set between the valve body 3; 20 sealings of O circle are set between top connection 21 and the sealing shroud 19.
On the above-mentioned valve body 3 with screw 17 attached cable pressing plates 18.
To the electric pump well that blowing is produced, adopt the utility model shunting ball-and-seat after, when electric pump is shut down, can not influence blowing production, the assurance of maximum possible oil well output; Improve the leakage of ball-and-seat, pump is played a protective role, prolong pump detection period, reduce operation number of times and operating cost; Shorten the activity duration, thereby increased the production time, increased output.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation:
The structural representation of Fig. 1 the utility model shunting ball-and-seat.
The specific embodiment
The shunting ball-and-seat of the utility model is threaded each other and is formed by lower contact 1, valve body 3, top connection 21; Wherein, above-mentioned valve body inside is made up of guide rod 5, valve seat 6, spool 8, little spring 9, little spring pad 10, spring 12, piston 13, strainer 14, piston guide cap 16 and sealing shroud 19; Above-mentioned guide rod 5 is positioned at spool 8 inside; Pin 4 passes spool 8 bottoms and guide rod 5 bottom fixed spools 8 and guide rods 5, and this spool 8 inserts in valve seats 6, and little spring 9 is positioned at the upper end of spool 8 inside and around guide rod 5; Be mounted with little spring pad 10 above the little spring 9; Piston 13 inserts in the spring 12, and valve seat 6 is threaded with piston 13, and strainer 14 is installed in the hole on the piston 13; Piston guide cap 16 is installed on the piston 13, and sealing shroud 19 is in valve body 3 inside.
Six screws, 2 fastening its are threaded with lower contact 1, top connection 21 in installing on the above-mentioned valve body 3.
7 sealings of O circle are installed between above-mentioned guide rod 5 and the spool 8; Piston 13 upper and lowers respectively and O circle sealing is set between the valve body 3; 20 sealings of O circle are set between top connection 21 and the sealing shroud 19.
On the above-mentioned valve body 3 with screw 17 attached cable pressing plates 18.
As shown in Figure 1, during use, the utility model shunting ball-and-seat is installed on the electric submersible pump, when driving a well; It is inner that liquid is given rise to the shunting ball-and-seat, and liquid rises and promotes spool 8 motions, and liquid flows through from the special construction of spool 8, and guide rod passes at valve core inside; Spool has little spring in the top, so can slide on guide rod top in spool top, the spool bottom is cylindrical, and bottom lowermost end chamfering is domatic to be 45 °; Run through for square opening in the middle of the spool lower cylindrical, when liquid promotes to move on the spool, around spool, flow into the square hole of spool bottom, because the sealing of spool upper piston; Liquid can flow nowhere, can only continue to promote spool top, and bottom, spool top structure chamfering is domatic to be 45 °, and the compression little spring; Then the spool upper and lower separates the flow pass space, and liquid therefrom flows into piston, continues to flow out the shunting ball-and-seat at last, gets into oil pipe; Valve seat 6 moves along with spool 8, and drive piston guide cap 16 docks with sealing shroud 19, forms sealing; When stopping well, liquid falls after rise, makes spool 8 counter motions, and piston 13 also recovers because of the elastic deformation of action of gravity and spring 12, drives valve seat 6 and falls after rise, and hermetic unit is opened, and whereabouts liquid flows into the oil jacket annular space.
Above the embodiment of the utility model has been done detailed description; But the utility model is not limited to above-mentioned embodiment; In the ken that affiliated technical field those of ordinary skill is possessed, can also under the prerequisite that does not break away from the utility model aim, make different the variation.
