Abstract
The utility model relates to a sealing device for an oil field, particularly to a sealer of an oil field well mouth. The technical solution is as follows: the sealer of the oil field well mouth mainly comprises a polish rod, a spherical base, a main body, a sealing ring, a flange disc, a pressure cover and a sleeve; the polish rod is fixed among the spherical base, the main body and the sleeve; the sealing ring is arranged between the polish rod and the sleeve; the arc part of the spherical base is matched with the conical surface of the main body; the lower end of the sleeve is sleeved on the main body; the pressure cover is arranged on the sealing ring; and a flange is arranged on the upper end face of the pressure cover, and fixed with the sleeve by a bolt. The utility model has beneficial effects of good sealing performance, convenience of exchanging a sucker rod and abrasion reduction; meanwhile, it is convenient to match with the other equipment; the spherical base is matched with the main body, so that the lower part of the spherical base is connected with a well mouth Christmas tree; as the end face of the spherical base is of spherical shape, it can be better matched with the conical surface of the main body; the problems of eccentric occurring between the polish rod and the sealing ring is reduced, and exchanging time of a packing is declined.
Description
Technical field
The utility model relates to a kind of oil field and uses sealing device, particularly a kind of oil field shaft mouth sealer.
Background technology
In the oil well repairing operation, mainly adopt packing that sucker rod is sealed at present, because packing and sucker rod sealing surface are cylindrical; Sealing device polished rod and packing eccentric wear phenomenon commonly used at present are serious, make packing impaired serious, and the life-span reduces; When changing packing, because packing is pressed in the packing box very closely, difficulty is big during replacing; Waste time and energy, influence field produces.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of oil field shaft mouth sealer is provided, and good airproof performance is convenient to sucker rod and is changed operation, reduces wear.
Its technical scheme is: mainly be made up of polished rod, spheric seat, main body, sealing ring, flange, gland, sleeve; Polished rod is fixed between spheric seat, main body and the sleeve, is provided with sealing ring between polished rod and the sleeve, the circular arc portion of spheric seat and the cone match of main body; The lower end socket main body of sleeve; Gland places above the sealing ring, and the upper surface of gland is provided with flange, and flange and sleeve pass through bolt.
The beneficial effect of the utility model is: good airproof performance; Be convenient to sucker rod and change operation; Reduce wear, convenient simultaneously and other devices are used, and match with main body through adopting spheric seat; The bottom of spheric seat connects the well head production tree, and the end face of spheric seat is spherical can the combination with the conical surface of main body preferably.Reduce the eccentric wear problem of polished rod and sealing ring, reduced the replacing of packing.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Last figure: polished rod 1, spheric seat 2, main body 3, sealing ring 4, flange 5, gland 6, cylindrical shell 7.
The specific embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of polished rod 1, spheric seat 2, main body 3, sealing ring 4, flange 5, gland 6, sleeve 7; Polished rod 1 is fixed between spheric seat 2, main body 3 and the sleeve 7, is provided with sealing ring 4 between polished rod 1 and the sleeve 7, the cone match of the circular arc portion of spheric seat 2 and main body 3; The lower end socket main body 3 of sleeve 7; Gland 6 places above the sealing ring 4, and the upper surface of gland 6 is provided with flange 5, and flange 5 passes through bolt with sleeve 7.
Through using this device; Can reach good airproof performance, be convenient to sucker rod and change operation, reduce wear; Convenient simultaneously and other devices are used; Through adopting spheric seat to match with main body, the bottom of spheric seat connects the well head production tree, and the end face of spheric seat is spherical can the combination with the conical surface of main body preferably.Reduce the eccentric wear problem of polished rod and sealing ring, reduced the replacing of packing.
