Abstract
A pumping well polish rod sealer is composed of an upper sealing body, an upper sealing element, a spring, a lower sealing element, a lower sealing body, a clamp, a steel ring, a clamp joint, a polish rod and an oil injection nozzle plug. Due to the pre-tightening effect of the spring, the sealing element can be automatically filled after being worn, and an oil extraction worker does not need to tightly press the sealing element. The sealing member is the toper, produces radial deformation easily, and when the polished rod went upward, lower sealing member played the main seal effect, goes up the sealing member and plays the supplementary seal effect, and when the polished rod went downward, lower sealing member played the supplementary seal effect, goes up the sealing member and plays the main seal effect, consequently, the utility model discloses a two way seal, the leakproofness is good. The inner hole axis of the lower sealing body coincides with the upper thread axis, and the inner hole axis of the lower sealing body and the upper thread axis do not coincide with the axis of the lower steel ring groove, so that the axes of the upper sealing member, the lower sealing member, the upper sealing member and the lower sealing member coincide with the axis of the polish rod, eccentric wear caused by non-concentricity of the polish rod and the sealing member can be prevented, the service life of the sealing member is long, and the time interval for additionally installing the sealing member is long.
Description
One, technical field:
The utility model is the pumpingh well polished rod sealer that oil exploitation is used.Belong to engineering goods.
Two, background technology:
Existing pumpingh well polished rod sealer kind is more, but all exists certain defective, as the polished rod sealer often pressure cap of tight moving polished rod sealer of workman that need recover the oil, could guarantee that polished rod sealer is oil-proof.The oil well that has is because of can not be in time tight dynamic pressure cap, and the frequent seepage of well head had both caused crude oil to land loss, caused environment pollution again.The oil well that has does not overlap with the axis of polished rod sealer owing to the polished rod axis, cause polished rod eccentric wear seal, need often to change the seal of pumpingh well polished rod sealer, seal large usage quantity not only, cost increases, and influences oil well output, economic loss is huge, since stop pumping change seal often on the pump sand grains in the oil pipe sink to causing the possibility of sand card oil well pump to increase, occur sometimes changing the problem that can not continue to drive a well behind the careful sealing, need the operation well workover could recover oil well production.
Three, summary of the invention:
The purpose of this utility model is a kind of pumpingh well polished rod sealer of design, the often tight pressure cap that moves polished rod sealer of workman that do not need to recover the oil just can guarantee sealing, make it have the tuningout function, seal is durable in use, does not need often to change seal, and the seal consumption reduces, save cost, the oil well off-time reduces, and production loss reduces, and significantly reduces oil recovery workman's workload and labour intensity.
The purpose of this utility model be achieved in that it by last seal, go up seal, spring, lower seal, lower seal body, clip, steel ring, thimble connector, polished rod, pump nozzle and stop up and form.Last seal is packed into and is gone up in the seal, lower seal is packed in the lower seal body, last seal bottom connects with lower seal body top, be spring between last seal and the lower seal, the lower seal body is connected by clip with thimble connector, between lower seal body and the thimble connector steel ring is arranged, and on the last seal oil filler point is arranged, pump nozzle stops up and is installed in seal oil filler point place, takes down pump nozzle and stop up the lubrication oil of can annotating in seal.Last seal, lower seal are taper, make it be easy to generate radial deformation, strengthen sealing performance, and last seal small end makes progress, and the lower seal small end is downward.Axially bored line overlaps with the top axis of thread in the lower seal body, the interior axially bored line of lower seal body and the top axis of thread not with the dead in line of bottom steel ring slot.
The beneficial effects of the utility model are: because the pretension effect of spring can clog behind the sealing part abrasion automatically, the tight movable sealing body of the workman that do not need to recover the oil, oil recovery workman workload is few, can not occur because of can not be in time the tightly well head leakage of oil that causes of movable sealing body.Last seal, lower seal are taper, are easy to generate radial deformation, and last seal small end upwards, the lower seal small end is downward, when polished rod was descending, lower seal played the primary seal effect, and last seal plays the auxiliary seal effect, when polished rod is up, lower seal plays the auxiliary seal effect, and last seal plays the primary seal effect, therefore, the utility model is a two way seal, good airproof performance.Because steel ring, clip are revolving body, therefore, but the eccentric axis of axially bored line and thimble connector is fixed after regulated at will again in the lower seal body, make after the axis of its upper and lower seal and upper and lower seal and the polished rod dead in line fixingly again, can prevent the eccentric wear that polished rod and seal decentraction cause, seal durability is long, seal can be realized durable in use, so the time interval of installing seal additional is long, labour intensity is low.
Four, description of drawings:
Accompanying drawing is the structure half sectional view of the utility model embodiment.
Five, specific embodiment:
Below in conjunction with accompanying drawing the utility model embodiment is described.
In the drawings: the 1st, last seal, seal on 2,3 springs, the 4th, lower seal, the 5th, the lower seal body, the 6th, clip, the 7th, steel ring, the 8th, thimble connector, the 9th, polished rod, the 10th, pump nozzle stops up.Be that the utility model is made up of last seal 1, last seal 2, spring 3, lower seal 4, lower seal body 5, clip 6, steel ring 7, thimble connector 8, polished rod 9, pump nozzle obstruction 10.Last seal 2 is packed into and is gone up in the seal 1, lower seal 4 is packed in the lower seal body 5, last seal 1 bottom connects with lower seal body 5 tops, be spring 3 between last seal 2 and the lower seal 4, lower seal body 5 is connected by clip 6 with thimble connector 8, between lower seal body 5 and the thimble connector 8 steel ring 7 is arranged, and on the last seal 1 oil filler point is arranged, pump nozzle stops up the 10 oil filler point places that are installed in seal 1, takes down pump nozzle obstruction 10 lubrication oil of can annotating in seal.Last seal 2, lower seal 4 are taper, make it be easy to generate radial deformation, strengthen sealing performance, and last seal 2 small ends make progress, and lower seal 4 small ends are downward.Axially bored lines overlap with the top axis of thread in the lower seal body 5, the lower seal body 5 interior axially bored lines and the top axis of thread not with the dead in line of bottom steel ring slot.
Install seal additional when preventing to produce and oil-spraying occurs, can on the utility model, design blowout hookup.
