Abstract
The utility model discloses an anti-theft polished rod sealing unit, belonging to the technical field of producing well port on the oilfield land. The polished rod sealing unit comprises a rubber gate, a packing, a packing box and a packing box pressure cap, wherein stop key slots are formed on the outer pipe wall of the packing box; a sealing washer is mounted at the lower part of the packing box; a seal packing, a seal gland bush, a sand prevention ring and a sand prevention packing are mounted on the sealing washer sequentially; the packing box pressure cap is connected with the packing box through threads; a pup joint is connected on the pipe wall of the packing box through threads; a locking device for the packing box and the packing box pressure cap is mounted in the pup joint; the pup joint passes through a protecting pup joint welded on the pipe wall of the packing box and is sealed; and the protecting pup joint is sealed by an anti-theft plug. The utility model adopts the two-stage packing seal to avoid sand and other foreign objects from entering the packing box, thereby prolonging the service life of the rod seal packing; and at the same time, the locking device for the packing box and the packing box pressure cap can effectively prevent law-breakers from dismantling the packing box to steal oil and environmental pollution accidents.
Description
Technical field: the utility model relates to a kind of antitheft polished rod sealer, belongs to ground, oil field production wellhead sealing device technical field.
Prior art: in mechanical oil recovery, rod pumping pump producing well proportion maximum, it is to rely on oil pumper, sucker rod that kinetic energy is delivered to underground oil well pump, crude oil is pumped into the oil pumping mode on ground.The oil pumper well head is by wellhead polish rod sealer sealed well bottom pressure, makes crude oil arrive measuring station by line transportation endlessly.
Existing polished rod sealer mainly is made up of packing box, packing box pressure cap, sealing ring gland, rubber gate etc.When oil pumper is normally pumped, have only seal box to seal, two rubber gates mainly are to play shut-in well when changing the rubber packing.The shortcoming that polished rod sealer mainly exists: the one, seal box can arbitrarily tighten and unload pine, and without any the anti-device that tightens and prevent unloading pine, the stolen molecule is often stolen crude oil in the mode of dismounting packing box from well head.The 2nd, seal box endoporus and polished rod annular space gap are bigger, poor sealing performance, the stolen molecule often damages packing with the son that sands, the mode of spreading glass and spreading steel ball and steals crude oil from well head on packing box.
Summary of the invention: the purpose of this utility model is in order to solve the defective of lawless person in destruction well head stolen such as oil pumper well head dismounting packing box, the sons that sands, a kind of antitheft polished rod sealer to be provided.
The utility model is made up of rubber gate, packing, packing box, packing box pressure cap; have the retaining keyway on the outer tube wall of packing box; the bottom is equipped with seal washer; sealed packing, gland, sand control ring and sand control packing are installed on seal washer successively; the packing box pressure cap is by on the packing box that is threaded; a pipe nipple has been threaded on the tube wall of packing box; the locking device of packing box and packing box pressure cap is installed in the pipe nipple; this pipe nipple is by the sealing of the protection pipe nipple on the tube wall that is welded on packing box, and the protection pipe nipple seals by screws valve for preventing illagel application.
The utility model adopts upper and lower twin-stage packing_seal, foreign matters such as prevention sand enter in the packing box, have improved the application life of polished rod seal packing, simultaneously, the locking device of packing box and packing box pressure cap can prevent effectively that the lawless person from unloading the accident generation of packing box stolen, contaminated environment.
