Abstract
The utility model belongs to an underground blanking plug device applied to adjust the flow rate and pressure of various underground eccentric distributors and eccentric bottom-hole regulators, which comprises a regulating stem 1, a screw cap 2 and a spring 3, wherein a spring 3 and a spring 2 are arranged outside the regulating stem 1 in turns. The utility model is characterized in that the model also comprises an upper body of a water faucet 4, a projecting cam 5 and a bolt 6, wherein the outside lower end of the screw cap 2 is connected with the upper body of the water faucet 4, the projecting cam 5 can be placed directly in the middle through hole of the upper body of the water faucet 4 and gets positioned through the bolt 6 and the thinnest part on the lower regulating stem 1 can pass the middle through hole of the projecting cam 5. The advantages of the utility model are simple structure, convenient installation and continuous regulation, which is applicable for underground distribution and bottom-hole regulation.
Description
Technical field: the utility model relates to the mechanical oil recovery technical field, belongs to the flow that is applied to the various eccentric injection mandrels in down-hole, eccentric production mandrel, pressure controlled down-hole blocking device especially.
Background technology: present normally used blanking plug locking mechanism has steel ball or does not have the cam of through hole, and the steel ball locking mechanism is stuck easily, and its locking is unreliable, does not have the camshaft of through hole not pass through, thereby can't reach the adjusting purpose by regulating shaft.
Summary of the invention: the purpose of this utility model has provided a kind of down-hole blanking plug with locking, release and governor motion, has solved that blanking plug under the conventional well can not pass cam and the problem of regulating continuously.
The down-hole blanking plug of the utility model design, comprise adjusting rod, nut, spring, adjusting rod has spring, nut outward successively, it is characterized in that: it also comprises water nozzle upper body, cam, screw, wherein the nut outer lower end links to each other with the water nozzle upper body, and cam can directly be put in the intermediate throughholes of water nozzle upper body, and by two screw location, the thinnest part in bottom of adjusting rod can be by the intermediate throughholes of cam.
The intermediate throughholes of water nozzle upper body is the long waist shaped through hole, and the intermediate throughholes of cam is the X-shaped through hole, and X-shaped through hole one end face of cam is fluted, and cam can radially be swung certain angle.Adjusting rod is a multidiameter, and its thinnest part can be by X-shaped through hole in the middle of the cam, and step part and cam groove are connected in the middle of it.
The utility model has the advantages that simple in structurely, easy for installation, can regulate continuously, be applicable to the down-hole water distribution, join product etc.
Description of drawings: Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the long waist shaped through-hole structure schematic diagram of water nozzle upper body;
Structural representation when Fig. 3 is the utility model and injection well downhole flow regulator work.
The specific embodiment: the utility model is elaborated below in conjunction with accompanying drawing.The down-hole blanking plug of the utility model design, comprise adjusting rod 1, nut 2, spring 3, spring 3, nut 2 are arranged outside the adjusting rod 1 successively, it is characterized in that: it also comprises water nozzle upper body 4, cam 5, screw 6, wherein nut 2 outer lower ends link to each other with water nozzle upper body 4, and cam 5 can directly be put in the intermediate throughholes of water nozzle upper body 4, and by two screws, 6 location, the thinnest part in bottom of adjusting rod 1 can be by the intermediate throughholes of cam 5.
The intermediate throughholes of water nozzle upper body 4 is long waist shaped through holes, and the intermediate throughholes of cam 5 is X-shaped through holes, and X-shaped through hole one end face of cam 5 is fluted, and cam 5 can radially be swung certain angle.Adjusting rod 1 is a multidiameter, and its thinnest part can be passed through cam 5 middle X-shaped through holes, and step part is connected with cam 5 groove fit in the middle of it.The maximum step surface of adjusting rod 1 is used for the location, and its top multidiameter is used for pulling and adjusting.
Down-hole blanking plug 7 and eccentric injection mandrel and blanking plug mating part 8 have been comprised among Fig. 2.When field conduct used, the down-hole blanking plug was thrown process cam 5 for 7 times and is overcome spring 3 power by external force and swing an angle to adjusting rod 1 upper end, made cam 5 enter its belly along the eccentric orfice neck inwall of eccentric injection mandrel and flicked the back locking.Catch on the adjusting rod 1 and carry when throw in catcher during 7 releases of down-hole blanking plug, the intermediate step of adjusting rod 1 partly breaks away from the groove of cam 5, at this moment cam 5 is swung the long waist shaped through hole that part that an angle exceeds cam 5 is imbedded water nozzle upper body 4 to adjusting rod 1 lower end under external force, thereby can trip out down-hole blanking plug 7, drive the purpose that adjusting rod 1 rotation reaches the adjusting flow thereby dock engagement with the upper end of adjusting rod 1 by special-purpose adjustment means.
