Abstract
The utility model relates to a polish rod sealing device used for a well head of a mechanical production well in an oil field, particularly is a self-lubricating anti-pollution polish rod sealer which comprises a self-lubricating anti-pollution device and a polish rod sealer. The self-lubricating anti-pollution polish rod sealer is composed of an upper end cover (1), a polish rod sealing cover (2), a polish rod sealing base (3), an oil storage cavity (4), an upper and a lower overflow oil pipes (5), a press cover (6), a sealing ring (7), a pressure pad (8), a sealing body (9), and a flange (10). Because adopting an oil removing device, the oil storage cavity, and the polish rod sealer, the self-lubricating anti-pollution polish rod sealer achieves the sealing, lubricating, cooling, and anti-pollution functions of the polish rod of the well mouth and has the advantages of novel design, reasonable structure, convenient operation, easy fabrication, and low cost, and is suitable for various mechanical production wells.
Description
The utility model relates to the polish rod seal device that uses on a kind of oil field machinery oil well well head, the anti-pollution polished rod sealer of self-lubricating type.
The polished rod sealer packing that present production wellhead generally uses is tightly waled polished rod, and the packing wearing and tearing are fast especially, cause the well head leakage of oil and contaminated environment; production there is very big negative effect; often change packing in addition, cause the waste of manpower and materials, influence the ordinary production of oil well.
The purpose of this utility model is to provide a kind of self-lubricating type to pollute polished rod sealer, and it can make the friction between polished rod and the packing obtain lubricated and cooling, prolongs the application life of packing, prevents that simultaneously leakage of oil from causing environment pollution, guarantees the ordinary production of oil well.
The utility model is to realize like this, it comprises the anti-pollution and polished rod sealer two parts of self-lubricating type, respectively by upper end cover (1), polished rod seal lid (2), polished rod seal seat (3), shoe cream room (4), outer oil spill pipe (5), gland (6), joint ring (7), pressure pad (8), seal (9), flange (10) are formed up and down; Upper end cover (1) and shoe cream room (4) are by being threaded, one tabula is arranged in the middle of in shoe cream room (4), polished rod seal seat (3) seal cover (2) is arranged at top, the centre accompanies joint ring (7), the bottom is the oil storage cavity, oil spill pipe (5) outside the outside of shoe cream room (4) is welded with up and down, shoe cream room (4) is threaded with seal (9); Seal (9) is followed successively by gland (6), joint ring (7) pressure pad (8) from top to bottom; Foot is flange (10).
Upper end cover (1) bears polished rod load, by polished rod seal lid (2), joint ring (6), the edible vegetable oil device that polished rod seal seat (3) constitutes is to remove the wetting crude oil of the up exposed surface of polished rod, and allow crude oil fall into shoe cream room (4), the edible vegetable oil device has with polished rod automatic deflection adjusting and edible vegetable oil function of exchange, prolong the application life of polished rod edible vegetable oil device and guarantee the outer fuel-displaced cleaning action of polished rod, the outer up and down oil spill pipe (5) of shoe cream room (4) outside weld is that the crude oil that packing is missed is discharged in assigned address or the container, shoe cream room (4) stores packing leakage crude oil, and when polished rod is descending, utilize the crude oil lubrication polished rod, absorb the heat that polished rod and packing friction produce simultaneously when polished rod is up, seal (9) is followed successively by gland (6) from top to bottom, joint ring (7) pressure pad (8) plays the sealing well head.
The utility model has been owing to adopted edible vegetable oil device, shoe cream room, polished rod sealer, finishes wellhead polish rod sealing, lubricated, cooling, anti-pollution, modern design, rational in infrastructure, easy to use, processing and manufacturing is easy, cost is low, is applicable to various mechanical oil wells, is easy to apply.
Figure is a structural representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is further described.
Shoe cream room 4 bottoms and polished rod seal body 9 are to compress screwed connection, and its outer 5 dress gate valve controls of oil spill pipe up and down have the effect of shackle handle concurrently; The edible vegetable oil device can freely move horizontally and fine motion up and down with polished rod, and dress oil resistant joint ring 7 is thoroughly to clean crude oil vitals on the polished rod in it.
