Abstract
The utility model discloses an energy-saving environmental-friendly packing box and relates to the field of oil production equipment. The energy-saving environmental-friendly packing box is formed by a pressure cap, a packing barrel, a center regulation seat, a center regulation pressure cap, an offset regulation ball, an offset regulation pressure cap and an offset regulation seat. A packing set in a cone cavity section of the packing barrel is of a shrinking shape from top to bottom in a manner that the outer diameter of the packing set is reduced along with the decrease of the inner diameter of the cone cavity section; a gland is arranged on the packing set; the pressure cap tightly presses the pressure cap to be in screwed connection with the upper end of the packing barrel; a boss at the lower end of the packing barrel is positioned on the center regulation seat; the center regulation pressure cap tightly presses the boss to be in screwed connection with the center regulation seat; the lower part of the center regulation seat is in screwed connection with the offset regulation ball; the offset regulation ball is positioned on the offset regulation seat; and the offset regulation pressure cap is clamped on a ball head of the offset regulation ball and is in screwed connection with the offset regulation seat. Due to adoption of a novel technology, phenomenon of eccentric wear between a sucker rod and packing is prevented; and particularly, due to adoption of a cone hole of the packing barrel, the utilization rate of the packing can be effectively improved, the use period of the packing is prolonged, and specially, the link of replacing the packing is saved. In addition, the energy-saving environmental-friendly packing box is simple and applicable, and thus, the product has wide market prospect, is greatly required, is reasonable in price and is energy-saving and environmental-friendly.
Description
Technical field
The utility model relates to field, oil field well head packing box used, relates in particular to a kind of energy-conserving and environment-protective packing box.
Background technology
at present, packing in production is short application life, packing loading and unloading difficulty, without anti-theft measure with without anti-corrosion measure, application life is short, and majority is made for soft material, in oil extraction in oil field, production wellhead is important oil production equipment, and the connector that on well head, promising sucker rod provides, reveal from the sucker rod connector in order to prevent well liquid, need to the packing box of anti-leak be installed in the connector upper end, and present packing box is due to reasons in structure, exist the tuningout weak effect, the packing utilization rate is low, change the packing cycle short, increased workman's labour intensity, extended maintenance time, lowered oil recovery efficiency, increased cost for oil production, waste and old packing under particularly changing easily pollutes environment.
Summary of the invention
The utility model is intended to for the deficiency that exists in background technology, and a kind of energy-conserving and environment-protective packing box that provides.
Energy-conserving and environment-protective packing box of the present utility model, to be consisted of by pressure cap, tuningout ball, tuningout pressure cap and tuningout seat in seat, accent in pressure cap, packing cylinder, accent, be divided into the cone chamber section of the equal chamber section on top and bottom in the cavity of described packing cylinder according to its internal diameter, the packing group in the section of cone chamber from top to bottom its external diameter is contraction-like along with reducing of cone chamber section internal diameter; Be provided with gland on the packing group, the upper end spiral shell of pressure cap compression gland and packing cylinder links and connects; On seat, during in accent, pressure cap compresses boss and transfers, the seat screw socket is connected the boss seat of packing cylinder lower end in transferring, and in accent, seat bottom screw socket is connecting the tuningout ball; The tuningout ball seat is on the tuningout seat, and the tuningout pressure cap is stuck on the bulb of tuningout ball and links with tuningout seat spiral shell and connects.
As further improvement of the utility model, packing cylinder external diameter with transfer in internal diameter in internal diameter, boss and the accent of pressure cap all leave the gap.
As further improvement of the utility model, the contact surface of the bulb of described tuningout ball and tuningout seat is provided with sealing ring.
As further improvement of the utility model, described pressure cap two ends have radially connected rotating spanner.
Energy-conserving and environment-protective packing box of the present utility model, tuningout is effective, the packing utilization rate is high, need not change packing, simple in structure, easy to maintenance.Can automatically realize centering, prevent the generation of the eccentric wear phenomenon of sucker rod and packing, the especially design of packing cylinder can effectively improve the packing utilization rate, extends the life cycle of packing, has guaranteed sealing effectiveness, can prevent effectively that the loose unloading packing pressure cap from draining the oil; Built-in polished rod subtracts rotten device can extend 4 times of polished rod application lifes, in addition simply applicable, so the market prospects of this product are very wide, and product demand is larger, reasonable price, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with 1 pair of the utility model energy-conserving and environment-protective packing box of accompanying drawing, be described further.
Energy-conserving and environment-protective packing box of the present utility model, to be consisted of by pressure cap 4, tuningout ball 5, tuningout pressure cap 6 and tuningout seat 7 in seat 3, accent in pressure cap 1, packing cylinder 2, accent, be divided into the cone chamber section of the equal chamber section on top and bottom in the cavity of its packing cylinder 2 according to its internal diameter, the packing group 9 in the section of cone chamber from top to bottom its external diameter is contraction-like along with reducing of cone chamber section internal diameter; Be provided with gland 8 on packing group 9, the upper end spiral shell that pressure cap 1 compresses gland 8 and packing cylinder 2 links and connects; On seat 3, during in accent, pressure cap 4 compresses boss 10 and transfers, seat 3 screw sockets are connected in transferring for 10 of the boss of packing cylinder 2 lower ends, and in accent, 3 a bottom screw socket is connecting tuningout ball 5; 5, tuningout ball is on tuningout seat 7, and tuningout pressure cap 6 is stuck on the bulb of tuningout ball 5 and links with tuningout seat 7 spiral shells and connects.Connected rotating spanner 12 at pressure cap 1 two ends radially.
Packing cylinder 2 external diameters with transfer in pressure cap 4 internal diameter, boss 10 and transfer in the internal diameter of seat 3 all leave the gap.
The contact surface of the bulb of described tuningout ball 5 and tuningout seat 7 is provided with sealing ring 11, also is provided with joint ring on the contact surface of tuningout pressure cap 6 and tuningout ball 5.
The utility model adopts and adds packing; easy to loading and unloading, quick, solved the loading and unloading hard problem in producing, reduce and reduce workman's labour intensity downtime, this packing is practical; bring up to 95% with comparing utilization rate by 20% with common disk, be 4-5 times of common packing service time.Adopt the locking and anti-theft device of sealer, avoided destruction sealer stolen, reduced environment pollution, packing four direction adjustment all around, packing box can be realized automatic centering with polished rod, has reduced the eccentric wear phenomenon; This packing has adopted conical design, has reduced the frictional force of packing and polished rod, has reduced motor load, has saved electricity consumption.For the well of seriously corroded, slow down polished rod corrosion by subtracting rotten device, extend polished rod application life.
