Abstract
The utility model provides a sealing oil wiper of a pneumatic oil rod, belongs to the field of oil field machines and aims at designing a special tool for taking out an oil suction rod and meanwhile sealing a wellhead in well repairing operation and the like where the oil suction rod needs to be taken out. A casing and a conical upper press cover, and the casing and a lower press cover respectively form a groove. A pneumatic packing element is inserted into the groove, the casing and the outside of the conical upper press cover are fastened through the packing element, the casing and the conical lower press cover are fastened through a connection press cover, the lower end of the connection press cover is a steam access tube, the casing is provided with a compression air connecting port, and the steam access tube is provided with a steam connecting port. The sealing oil wiper of the pneumatic oil rod is simple in structure, convenient in use, capable of sealing the wellhead whiling taking out the oil suction rod during work, preventing crude oil in the well from jetting out and wiping off the crude oil attached to the outer wall of the oil suction rod. Waste and pollution of the crude oil to the environment are avoided.
Description
Technical field
The utility model belongs to the oilfield machinery field.
Background technology
In the work in oil field; Sometimes need carry out workover treatment; Workover treatment just need be taken out sucker rod from oil well, general present oil field is when workover treatment plays sucker rod, owing to there is not special tool to seal well head; The crude oil that when playing the bar operation, the brings out contaminated environment that falls to the ground, and cause unnecessary waste.
Summary of the invention
The purpose of the utility model is when designing a kind of special tool well workover etc. is needed to take out the sucker rod operation, can when taking out sucker rod, can seal the pneumatic beam hanger sealing oil wiper of well head again.
Shell of the utility model and taper upper press cover, shell and taper lower cover are formed a groove respectively; Pneumatic packing element is inserted in the groove; The outside of shell and taper upper press cover is fastening through the packing element gland, and shell is fastening through being connected gland with the taper lower cover, and connecting the gland lower end is the steam access tube; The compressed air interface is arranged on shell, on the steam access tube, vapor interface is arranged.
The pneumatic packing element of the utility model is inserted in the groove and becomes profile of tooth to contact with the housing contacts face.
Between the shell of the groove that shell of the utility model and taper lower cover are formed and taper lower cover one hole slot is arranged, the end of pneumatic packing element places in the hole slot.
The taper upper press cover of the utility model and the sidewall of taper lower cover are tapered from inside to outside.
The utility model is simple in structure, and is easy for operation, when operation, trip out sucker rod in the sealing well head, prevent crude oil ejection in the well, and the crude oil that adheres on the sucker rod outer wall that trips out scraped.Prevented pollution and the waste of crude oil to environment.
Description of drawings
Fig. 1 is the utility model structure sectional view.
The specific embodiment
The shell 1 of the utility model is formed a groove respectively with taper upper press cover 4, shell 1 and taper lower cover 7; Pneumatic packing element 2 is inserted in the groove; The two ends of pneumatic packing element 2 are inserted in the groove closely, and the outside of shell 1 and taper upper press cover 4 is fastening through packing element gland 5, and shell 1 is fastening through being connected gland 9 with taper lower cover 7; Taper upper press cover 4 can compress taper upper press cover 4 and taper lower cover 7 and shell 1 through being threaded on the shell 1 with taper lower cover 7 basically.Connecting gland 9 lower ends is steam access tubes 3; Compressed air interface 6 is arranged on shell 1; Compressed air interface 6 feeds between shell 1 and the pneumatic packing element 2, after compressed air feeds between shell 1 and the pneumatic packing element 2 through compressed air interface 6, pneumatic packing element 2 is inwardly pushed.Vapor interface 8 is arranged on steam access tube 3.
The pneumatic packing element 2 of the utility model is inserted in the groove and becomes profile of tooth to contact with shell 1 contact surface.The staggered contact of this profile of tooth has increased the sealing of shell 1 and pneumatic packing element 2 ends, and the compressed air of feeding can not be revealed.
The shell 1 and 7 of the taper lower covers of the groove that shell 1 of the utility model and taper lower cover 7 are formed have a hole slot, and the end of pneumatic packing element 2 places in the hole slot.This kind structure has promptly increased the sealing of shell 1 with pneumatic packing element 2, can increase the tightness of shell 1 and pneumatic packing element 2 again.
The taper upper press cover 4 of the utility model and the sidewall of taper lower cover 7 are tapered from inside to outside.Convenient pneumatic packing element 2 inserts in the groove.
There is the packing element gland shell upper end; Be used for being equipped with on the fit sealing packing element middle-end compressed air interface; Shrink to the center at compressed-air actuated promotion lower rubber cylinder; The annular space of sucker rod and beam hanger is sealed because packing element design is longer, beam hanger box cupling and wiper block through the time can both guarantee good sealing.The shell lower end links to each other with steam feeding tube, and the steam connector is housed on the steam feeding tube, if bleeder or other drainage devices are arranged in the well, can insert steam through this mouthful and carry out wax removal in the well.If there is not drainage device in the well, also can connects and go up the pipeline draining through this mouthful.
