Abstract
The utility model belongs to the technical field of a sealing piece and discloses a polish rod sealer. The utility model has the main technical characteristics that the polish rod sealer comprises a sleeve; an open-and-close sealing housing is arranged in the sleeve; the top end of the sleeve is provided with a compaction housing and an end cover; the inner wall of the sealing housing is provided with at least one path of sealing ring; and the inner wall of the sleeve matched with the sealing housing is of the frustum shape with the upper part being big and the lower part being small. For the polish rod sealer, the contact area of the sealing housing and a polish rod is reduced, therefore, the resistance to the polish rod in sealing is small, and the service life of the polish rod is long; after the sealing housing is abraded, the sealing housing can be frapped under the action of the inner wall of the sleeve in the frustum shape with the upper part being big and the lower part being small by screwing the end cover, so that the sealing housing can keep on holding the polish rod tightly, so as to play a role of sealing.
Description
Technical field
The utility model belongs to the seal technical field, relates in particular to a kind of polished rod sealer.
Background technology
In the oil field operation,, sealer need be set in the bottom that lifts with polished rod for preventing to occur in the manufacturing process leakage of crude oil.Presently used sealer comprises that inside is provided with the sleeve of rubber sealing boot, and sleeve inner is provided with boss to place rubber sealing boot, and the top of sleeve is provided with clamping sleeve that rubber sealing boot is compressed and the end cap that is connected with bush whorl.In order to be easy to change, rubber sealing boot adopts retractable structure, puts in rubber seal and has longitudinal crack, and breaking rubber sealing boot into two with one's hands by cracks can be with it by taking off on the polished rod or it being installed on the polished rod.This sealer is enclosed within sleeve, rubber sealing boot, clamping sleeve and end cap on the polished rod during use, then end cap and sleeve is screwed, and end cap is exerted pressure to rubber sealing boot by clamping sleeve.Rubber sealing boot one end is pushed by clamping sleeve, and the other end is stopped by boss and expands, and plays sealing function thereby hold polished rod tightly.After using a period of time, rubber sealing boot is worn, and end cap is continued to screw, and makes rubber sealing boot continue to seal.Though the sealer sealing effectiveness of this structure is pretty good, the inwall of rubber sealing boot is a smooth cartridge type up and down, also polished rod is produced bigger resistance when tightly holding tightly, both wastes energy, and quick abrasion, application life are short again.
The utility model content
Problem to be solved in the utility model just provides that a kind of resistance that polished rod is produced is little, the polished rod sealer of long service life.
For addressing the above problem, the technical solution adopted in the utility model is: comprise that inside is provided with the sleeve of opening-closing type sealing shroud, the top of sleeve is provided with clamping sleeve and end cap, and the inwall of described sealing shroud is provided with at least one joint ring.
Its additional technical feature is: described joint ring is together; Described joint ring is twice; Described joint ring is three roads or more than three roads; Be provided with adapter sleeve between described sealing shroud and clamping sleeve; Described clamping sleeve and adapter sleeve socket connection; Described clamping sleeve is provided with outer press ring, and end cap contacts with outer press ring; Described sleeve and the inwall sealing shroud matching part are up big and down small frustum.
Polished rod sealer provided by the utility model compared with prior art, the inwall of sealing shroud is provided with at least one joint ring, make that the inwall of sealing shroud is a concave-convex type, sealing shroud and polished rod contact area reduce, compare for the sealing shroud of smooth up and down cartridge type with inwall, inwall is little, the long service life of resistance that the sealing shroud of concave-convex type produces polished rod.According to different requirements, joint ring can be together, twice, three roads or more than three roads.And being provided with adapter sleeve between sealing shroud and clamping sleeve, clamping sleeve and adapter sleeve socket connection make clamping sleeve to the sealing shroud uniform force application.Clamping sleeve is provided with outer press ring, and end cap contacts with outer press ring, and end cap to the clamping sleeve effect, helps clamping sleeve work by outer press ring.And sleeve and the inwall sealing shroud matching part are up big and down small frustum, make sleeve inner boss need not be set again to place rubber sealing boot, after sealing shroud is worn, screw end cap once more, end cap by outer press ring to the clamping sleeve effect, clamping sleeve presses down sealing shroud by adapter sleeve, and sealing shroud is tightened up under up big and down small frustum sleeve lining effect, continues to hold tightly polished rod and plays sealing function.
Description of drawings
Fig. 1 is the structural representation of the utility model polished rod sealer;
Fig. 2 is the structural representation of sealing shroud;
Fig. 3 is the longitudinal sectional view of sealing shroud.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model polished rod sealer.
As shown in Figure 1, the utility model polished rod sealer comprises sleeve 1, sleeve 1 inside is provided with sealing shroud 2, be provided with adapter sleeve 3, clamping sleeve 4 and end cap 5 above the sealing shroud 2, clamping sleeve 4 and adapter sleeve 3 socket connections, clamping sleeve 4 is provided with outer press ring 6, and end cap 5 contacts with outer press ring 6, and sleeve 1 and inwalls 7 sealing shroud 2 matching parts are up big and down small frustum.As shown in Figure 2, sealing shroud 2 has longitudinal crack 8, and the inwall of sealing shroud 2 is provided with joint ring 9.As shown in Figure 3, joint ring 9 is twice, and sealing shroud 2 inwalls are concave-convex type.
During use, sleeve 1, sealing shroud 2, adapter sleeve 3, clamping sleeve 4 and end cap 5 are enclosed within on the polished rod 10, then end cap 5 and sleeve 1 are screwed, end cap 5 is by 4 effects of 6 pairs of clamping sleeves of outer press ring, clamping sleeve 4 presses down sealing shroud 2 by adapter sleeve 3, sealing shroud 2 tightens up under the 1 inwall effect of up big and down small frustum sleeve, holds polished rod 10 tightly and plays sealing function.After sealing shroud 2 is worn, screw end cap 5 once more, end cap 5 is by 4 effects of 6 pairs of clamping sleeves of outer press ring, and clamping sleeve 4 presses down sealing shroud 2 by adapter sleeve 3, sealing shroud 2 is tightened up under up big and down small frustum sleeve lining effect once more, continue to hold tightly polished rod 10 and play sealing function.
