Abstract
The utility model relates to a self-locking deviation adjusting type polished rod sealer used for an oil production wellhead. The polished rod sealer adopts the technical proposal that the whole body presents an up-down structure connection, a collar clamp head is respectively connected with a casing and a deviation adjusting seat from bottom to up, an O-ring seal is adopted between the collar clamp head and the deviation adjusting seat, ensuring both not to be leaked, the deviation adjusting seat is connected with a main body through a thread, a locating pin is arranged on the deviation adjusting seat, the lower part of the inner hole of the main body is matched with a split packing to form a secondary seal, the outer circle of the split packing and the main body adopt a cone-shaped matching, is provided with two small springs, and the upper part of the inner hole of the main body is matched with a cone-shaped spiral packing to form a primary seal. The polished rod sealer has the advantages that because the cone-shaped spiral packing is matched with the taper in the main body, the polished rod sealer crimples downward when the pressing cap presses the polished rod sealer tightly, leading the spiral packing to grip the polished rod to achieve the sealing function, the polished rod sealer has the automatic adjusting function after being screwed through the springs, and is not required to be checked every day, thereby being very convenient, time saving and labor saving, and improving the service life.
Description
One, technical field:
The utility model relates to the polished rod sealer that a kind of production wellhead is used, and particularly relates to a kind of self-tightening deviation adjustment type polished rod sealer.
Two, background technology:
At present the product category of polished rod sealer has a variety ofly, but polished rod seal, tuningout problem can not solve always fully, and subject matter is to adopt square packing pad, and fixed form is tuningout not.Misalign the heart because well head has inclined shaft and oil pumper to install with well head, make polished rod and polished rod sealer produce eccentric wear, cause packing, polished rod and polished rod sealer to shorten application life, cause the waste of human and material resources.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of self-tightening deviation adjustment type polished rod sealer is provided, thereby solves the polished rod sealer sealing problem, and packing_seal and application life are increased.
Its technical scheme is: by the clip head, shell, O type circle, the tuningout seat, the opposite opened packing, little spring, alignment pin, positioning seat, long handle, tapered Screw disk-seal tube, main body, short handle, spring base, spring, accessories such as pressure cap are formed, integral body is up and down, and structure connects, be respectively clip head and shell from bottom to up, the tuningout seat connects, the sealing of O type circle is arranged between clip head and the tuningout seat, guarantee non-leakage between the two, tuningout seat and main body are with being threaded, and installing and locating pin, the endoporus bottom of main body cooperates with the opposite opened packing forms secondary seal, the cylindrical of opposite opened packing is tapered the cooperation with main body, and have two little springs, the endoporus top of main body cooperates with tapered Screw disk-seal tube forms primary seal, main body and pressure cap be with being threaded, and spring base and spring are arranged in the pressure cap.
Pressure cap, short handle are yi word pattern and both sides alignment, are placed with spring, spring base in the pressure cap, and tapered Screw disk-seal tube is tapered the cooperation with main body.
The endoporus of two up and down of main body all is tapered cooperation, and the tapered Screw disk-seal tube of the higher authorities cooperates with main body, and following opposite opened packing cooperates with main body, and the tapered angle in two is different, and two long handles of welding in the middle of the main body cylindrical are the alignment of yi word pattern both sides.
The cylindrical top installing and locating assembly of tuningout seat, locating assembly comprises positioning seat, alignment pin and spring.
When adding tapered packing pad, in order to guarantee that oil is not from seepage between polished rod and the packing, must start secondary seal, secondary seal adopts the opposite opened packing, cylindrical is tapered the cooperation with main body, and have two little springs, at first alignment pin is pulled out, the long handle that moves in the direction of the clock makes main body move down compressing opposite opened packing and merges, and firmly embrace polished rod and reach sealing function, add tapered packing pad then, tapered packing pad also adopts spiral to cut, and lobe is opened otch and directly is put into the inside and gets final product during interpolation, after having added tapered packing pad, by counterclockwise rotating, apart from alignment pin automatic homing when 8mm greatly, main body is got back to the origin-location between main body and the tuningout seat, the opposite opened packing by two little spring effects naturally separately no longer plays sealing function.
The beneficial effects of the utility model are:
(1) owing to adopts tapered Screw disk-seal tube to match with the main body internal taper, when compressing, pressure cap down tightens automatically, make Screw disk-seal tube tightly embrace polished rod and reach sealing function, and old-fashioned polished rod sealer adopts square packing pad, compress by pressure cap, in use because the twitch that polished rod does not stop, packing is lined with wearing and tearing, so all will check and screw every day, bothers very much, and self-tightening deviation adjustment type polished rod sealer is on the basis of tapered Screw disk-seal tube, add upper spring, automatic regulatory function is arranged after screwing, do not need all will check every day, so it is very convenient, time saving and energy saving;
(2) design has the tuningout function, after self-tightening deviation adjustment type polished rod sealer is installed, do not screw shell, allow clip head and shell tuningout seat that the free gap is arranged, start oil pumper work then polished rod is pumped, the tuningout seat can be adjusted the center with polished rod automatically with upper-part, screws shell then, not eccentric wear of self-tightening deviation adjustment type polished rod sealer is guaranteed in the location, improves application life.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
