Abstract
The utility model relates to a water distributing packer, which belongs to an underground water distributing part of petroleum machinery. The utility model comprises a lower connector 22, an eccentric body 20, a guide body 19, a lower connector 17, a changing head 16, a connector 14 and a connecting pipe 15, etc. The utility model is characterized in that an outer pipe 5 is in sliding connect with a central pipe 12; a circlip seat 11 is clamped with the outer pipe 5; a circlip 10 is arranged on the circlip seat; an outer working cylinder 9 is in sliding connection with the circlip seat; a rubber barrel 7, a spacing ring 6, and a press cap 8 are in sliding connection with the outer pipe 5. The utility model has the advantage that the structure is novel; the structure of an original water distributing packer can be changed; a washing well sleeve is omitted, causing that the diameter is reduced; after the deformation of the sleeve cylinder caused by use is generated, the lower part of the outer cylinder can also enter the sleeve cylinder; thereby, the normal process for producing can be ensured.
Description
Technical field
The utility model belongs to petroleum machinery down-hole water distribution parts.
Background technology
Present water distribution packer, because of having the well-flushing cover in its structure, the promotion of overlapping by this well-flushing makes the glue tube base envelope, its shortcoming is: the diameter of urceolus can not diminish, after sleeve produces distortion because of use, make under the urceolus not advance in the sleeve, influenced normally carrying out of producing.
Summary of the invention
The utility model provides a kind of water distribution packer, makes problem that not advance under the urceolus in the sleeve after because of distortion to solve because of sleeve.The technical scheme that the utility model is taked is: lower contact 22 is threaded by lower outer pipe 21 with eccentric body 20, guide way 19 is threaded by following tube connector 18 with lower union joint 17, becoming 16 is threaded by tube connector 15 with connector 14, between central tube 12 and the connector 14 cushion rubber 13 is arranged, top connection 1 is threaded with central tube 12, piston 2 is slidingly connected with central tube 12, between piston 2 and the outer working tube 4 sealing ring 3 is arranged, outer tube 5 is slidingly connected with central tube 12, clip spring seat 11 and outer tube 5 clampings, jump ring 10 is arranged on this clip spring seat, and outer working tube 9 is slidingly connected packing element 7 with clip spring seat, spacer ring 6 and pressure cap 8 are slidingly connected with outer tube 5.During use, when will carrying out seat when envelope, water enters connector 14 and becomes between 16 the hole from central tube 12, promote connector 14, outer working tube 9, pressure cap 8, and last under the promotion of pressure cap, packing element 7 expands and seals.
The utility model has the advantages that: novel structure, changed the structure of original water distribution packer, removed the well-flushing cover, make its reduced, can after producing distortion because of use, sleeve also can make under the urceolus to advance in the sleeve, and what guaranteed to produce normally carries out.
