Abstract
The utility model relates to polish rod sealing devices, specifically to a novel environment-friendly polish rod sealer comprising a pressing cap, a main packing box, a lower packing box, an upper pressing sleeve, an upper centering block, upper rubber packing, a lower pressing sleeve, a lower centering block and lower rubber packing. The upper packing box and the lower packing box are disposed on the upper side and the lower side of the main packing box respectively; the upper rubber packing is disposed in the inner cavity of the upper packing box; the upper portion of the upper packing box is connected with the pressing cap; the upper centering block and the upper pressing sleeve are disposed in the pressing cap; the lower rubber packing is disposed in the inner cavity of the lower packing box; and the lower centering block and the lower pressing sleeve are disposed in the cavity between the lower packing box and the main packing box. A grease chamber disposed in the main packing box achieves a lubricating effect and the upper and lower groups of packing can reinforce the seal effect. Conical inner walls at the bottom of the packing boxes enable the packing to be consumed effectively, so that the frequent replacement of the packing is not needed, the packing needs not to be changed even for a long time and only adding of the packing is needed.
Description
Technical field
The utility model relates to a kind of polish rod seal device, particularly a kind of novel environment friendly polished rod sealer.
Background technology
A kind of sealer that can solve oil-extractor polish-rod sealing leak problem of polished rod sealer.At present, the polished rod sealer that rod-pumped well adopts, most packing-type packing seal structure that adopt, the packing life cycle of this structure is short, frequently change; Also the grease seal chamber that arranges useless in addition, its sealing effectiveness is bad.If Chinese patent literature number is cn2861462, a kind of < < pumping unit rod sealing device > > is disclosed, comprise pressure cap, spring, filler, jube, gland, packing box, universal joint, packing, tuningout pressure cap, spherical sealing element, erection device and ball joint, described packing box upper end is installed on pressure cap, lower end is connected with universal joint, inside is installed on jube from bottom to top in turn, packing, gland, jube, filler and spring, described universal joint lower end is installed on ball joint and spherical sealing element, ball joint top is installed on tuningout pressure cap, inner chamber is installed on erection device.This utility model patent has tuningout, righting function, is widely used in pump well polish-rod sealed disk technique.But the problem of its existence is: packing life cycle is short, frequently replacing, thereby has increased spillage of material and reduced productivity effect.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of novel environment friendly polished rod sealer is provided, and packing can all consume, and can realize and not change for a long time packing.
Its technical scheme is: comprise pressure cap, main packing box, lower packing box, upper gland, upper wiper block, upper rubber packing, lower gland, lower wiper block, lower rubber packing, the both sides up and down of described main packing box are respectively equipped with packing box and lower packing box, upper packing box inner chamber is provided with rubber packing, the top of upper packing box connects pressure cap, is provided with wiper block and upper gland in pressure cap; Lower packing box inner chamber is provided with lower rubber packing, is provided with lower wiper block and lower gland in the cavity between lower packing box and main packing box.
One side of above-mentioned main packing box is provided with grease nipple, and opposite side is provided with bleeder screw.
Above-mentioned lower packing box and the bottom of upper packing box are conical inboard wall.
The beneficial effects of the utility model are: the butter chamber being provided with in main packing box, can play lubrication, upper and lower two groups of packings can booster sealing effectiveness, in addition, the conical inboard wall that packing box bottom is provided with can effectively run out of whole packings, do not need frequently to change packing, can realize for a long time and need not change packing, only need to add packing.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: polished rod 1, pressure cap 2, main packing box 3, bleeder screw 4, lower packing box 5, upper gland 6, upper wiper block 7, upper rubber packing 8, conical inboard wall 9, grease nipple 10, lower gland 11, lower wiper block 12, lower rubber packing 13, upper packing box 14.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises pressure cap 2, main packing box 3, lower packing box 5, upper gland 6, upper wiper block 7, upper rubber packing 8, lower gland 11, lower wiper block 12, lower rubber packing 13, the both sides up and down of described main packing box 3 are respectively equipped with packing box 14 and lower packing box 5, upper packing box 14 inner chambers are provided with rubber packing 8, the top of upper packing box 14 connects pressure cap 2, is provided with wiper block 7 and upper gland 6 in pressure cap; Lower packing box 5 inner chambers are provided with lower rubber packing 13, are provided with lower wiper block 12 and lower gland 11 in the cavity between lower packing box 5 and main packing box 3.
Wherein, a side of main packing box 3 is provided with grease nipple 10, and opposite side is provided with bleeder screw 4, and above-mentioned lower packing box 5 and the bottom of upper packing box 14 are conical inboard wall 9.
Advantage of the present utility model is as follows:
The butter chamber being provided with in main packing box, can play lubrication, and upper and lower two groups of packings can booster sealing effectiveness, and in addition, the conical inboard wall that packing box bottom is provided with can effectively run out of whole packings, does not need frequently to change packing; Two wiper blocks have the effect of deflection-regulating centralizing.
