Description
Technical field:
The utility model is the wellhead equipment that oil exploitation is used, and is a kind of pumpingh well polished rod sealer.
Background technology
When pumpingh well is pumped with sucker rod in order to prevent blowout, to on the flow tee of wellhead assembly, sealer be installed, the bar top of passing sealer connects oil pumper, the bottom connects sucker rod, in order to guarantee and the sealer fitted seal, the bar Surface Machining of passing sealer is very smooth, so be called polished rod, its sealer also just is called polished rod sealer, and existing pumpingh well polished rod sealer kind is more, but all exists certain defective, if any poor sealing, the frequent leakage of oil of well head had both caused the crude oil loss, caused environment pollution again.For fear of the well head leakage of oil, need often to change the seal of pumpingh well polished rod sealer, the seal large usage quantity, cost increases, and labor strength is big, and frequent stop pumping is changed seal and made the sinking of the sand grains in the oil pipe on the pump easily, cause sand card oil well pump, occur 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, the economic loss tool is big.
Summary of the invention
The purpose of this utility model is a kind of pumpingh well polished rod sealer of design, makes the seal of its pumpingh well polished rod sealer durable in use, reduces labor strength.
The purpose of this utility model is achieved in that and comprises clamping nut, working seal spare, seal, the blowout prevention seal, adapter sleeve, the aligning gland, the aligning joint, the aligning seat, the well head connector, aligning joint inside is hollow-core construction, the bottom is a sphere structure, the bottom spheroid seat of aligning joint is on the aligning seat, both contact surfaces are spherical, aligning seat seat is on the well head connector, the aligning gland is enclosed within the top of the bottom spheroid of aligning joint, both contact surfaces are spherical, adapter sleeve inner circular bead cover is on the upper surface of aligning gland, the adapter sleeve bottom is connected with the well head connector, the blowout prevention seal is installed in the cavity of resorption of seal, the seal lower thread is threaded with aligning joint top, installation work seal in the epicoele of seal, clamping nut is threaded with seal top, clamping nut compression work seal, the external diameter of aligning gland is greater than the upper port diameter of adapter sleeve, aligning gland, the external diameter of aligning seat is less than the internal diameter 3-15mm of adapter sleeve.
The external surface of working seal spare, blowout prevention seal is a pyramidal structure, and the epicoele of the seal that is mated and cavity of resorption also are pyramidal structure, and tapering is identical.
The beneficial effects of the utility model are: the aligning gland, gapped between aligning seat and the adapter sleeve, the aligning gland, the aligning seat can move arbitrarily in adapter sleeve diametrically, its center that is installed in seal on the aligning joint is overlapped with the center of the polished rod that passes, working seal spare is eccentric wear not, aligning joint bottom is a sphere structure, can rotate to all directions, also can tilt with the polished rod that passes, the strength of not spraining between polished rod and the seal, the long service life of seal, durable in use, avoided pumpingh well to need problems such as pumpingh well production loss that stop pumping causes and sand card oil well pump because of the frequent seal of changing, can significantly reduce workman's workload and labour intensity, have remarkable economic efficiency.
Description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
Specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises clamping nut 1, working seal spare 2, seal 3, blowout prevention seal 4, adapter sleeve 5, aligning gland 6, aligning joint 7, aligning seat 8, well head connector 9, aligning joint 7 inside are hollow-core construction (can pass polished rod), the bottom is a sphere structure, the bottom spheroid seat of aligning joint 7 is on aligning seat 8, both contact surfaces are spherical, 8 of aligning seats are on well head connector 9, aligning gland 6 is enclosed within the top (being on the central plane of asking body) of the bottom spheroid of aligning joint 7, both contact surfaces are spherical, adapter sleeve 5 inner circular bead covers are on the upper surface of aligning gland 6, adapter sleeve 5 bottoms are connected with well head connector 9, blowout prevention seal 4 is installed in the cavity of resorption of seal 3, seal 3 lower thread are threaded with aligning joint 7 tops, installation work seal 2 in the epicoele of seal 3, clamping nut 1 is threaded with seal 3 tops, clamping nut 1 compression work seal 2, making working seal spare 2 encase polished rod does not leak, the external diameter of aligning gland 6 is greater than the upper port diameter of adapter sleeve 5, it can not come off with adapter sleeve 5, aligning gland 6, the external diameter of aligning seat 8 makes aligning gland 6 less than the internal diameter 3-15mm of adapter sleeve 5, the scope of activities of aligning seat 8 can satisfy the requirement of tuningout.
Further scheme of the present utility model is that the external surface of working seal spare 2, blowout prevention seal 4 is a pyramidal structure, the epicoele of the seal 3 that is mated and cavity of resorption also are pyramidal structure, and tapering is identical, so that more be easy to generate radial deformation when compressive seal, improves sealing.
The effect of blowout prevention seal 4 is in maintenance or plays a part to cut off pressure when changing working seal spare 2, and making in the epicoele of seal 3 does not have pressure, and blowout prevention seal 4 is in releasing orientation and does not contact with polished rod during production.
When the utility model is installed on the wellhead assembly, the connection of thread of adapter sleeve 5 bottoms and well head connector 9 is not tightened earlier, at this moment, the axle center of aligning joint 7 can be adjusted, and treats that working seal spare 2, seal 3 tighten the connecting thread of adapter sleeve 5 and well head connector 9 after concentric again with polished rod.
