Description
Technical field
The utility model relates to the wellhead polish rod sealing device of oil exploitation, particularly a kind of Multifunction packing box.
Background technology
Oil well production mostly is sucker rod pumping at present, and crude oil enters oil pipeline by the well head of polished rod and packing_seal, and polished rod, in the process of moving up and down, due to many reasons, causes well head not just, polished rod bias.Cause sealing device not exclusively to seal, this will make well head leakage of oil, environment pollution.Particularly comprehensive regulation aspect, often unloaded packing box, causes the pollution in wide area of oil well.Therefore, along with the implementation of cleaner production mode, the leakage of oil of regulation well head, alleviate workload, and energy-saving and emission-reduction, seem and be even more important.
The utility model content
The purpose of this utility model is to provide a kind of Multifunction packing box, overcomes the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises the one-level packing box, secondary packing box and rubber gate, it is characterized in that the secondary seal packing box comprises secondary packing box body, sealer, adjustment seat and pressure cap, the one-level packing box comprises the top connection of rubber gate, be located at the monosymmetric spill opening in rubber gate top connection top, be located at the packing pressure pad on rubber gate top connection top, be located at the monosymmetric protruding tongue in top on the packing pressure pad, the one-level packing is located in the rubber gate top connection, the packing pressure pad is pressed on the one-level packing, and the protruding tongue of packing pressure pad is in the spill opening of rubber gate top connection, secondary packing box bottom is threaded with the rubber gate top connection, central part at the secondary packing box is provided with the sealer that two ends are convex arc surface, and the upper and lower side at sealer is provided with the concaved circular cambered surface adjustment seat, the top of secondary packing box is provided with the pressure cap be threaded.
One end of adjustment seat is made as plane, and the other end is made as concaved circular cambered surface, and center is provided with the polished rod hole, and plane and the pressure cap of the adjustment seat of sealer upper end are slidably matched, and adjustment seat plane and the secondary packing box of lower end are slidably matched.
Sealer is made as cylindrical, in sealer, is provided with the secondary seal packing, and the convex arc surface of top and bottom and the concaved circular cambered surface of adjustment seat are slidably matched.
The packing pressure pad is made as cylindrical, and center is provided with the polished rod hole, is provided with two symmetrical protruding tongues at packing pressure pad outer circumferential side middle part, and thoughtful periphery is provided with symmetrical circular hole in top.
The secondary packing box is made as cylindrical, and upper diameter is greater than lower diameter, and top is provided with the male thread be threaded with pressure cap, and bottom is provided with the box thread be threaded with the rubber gate top connection.
Compared with the prior art the utility model has the following advantages:
1, have secondary seal and automatic deflection adjusting function, improved the effect of wellhead sealing, extended sealed packing application life, guaranteed that well head is oil-proof.
2, the secondary seal packing can disposablely be released, and is convenient to change, and the primary seal packing only has with special tool could change the primary seal packing to the sealed pressure pad proposition, has the function of guard against theft oil.
The accompanying drawing explanation
Fig. 1-structural representation of the present utility model;
1-pressure cap in figure, 2-sealer, 3-adjustment seat, 4-secondary packing box, 5-packing pressure pad, the top connection of 6-rubber gate, 7-rubber gate.
The specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises the one-level packing box, secondary packing box 4 and rubber gate 7, it is characterized in that secondary seal packing box 4 comprises secondary packing box body, sealer 2, adjustment seat 3 and pressure cap 1, the one-level packing box comprises the top connection of rubber gate, be located at the monosymmetric spill opening in rubber gate top connection top, be located at the packing pressure pad 5 on rubber gate top connection top, be located at the monosymmetric protruding tongue in top on the packing pressure pad, the one-level packing is located in the rubber gate top connection, packing pressure pad 5 is pressed on the one-level packing, and the protruding tongue of packing pressure pad 5 is in the spill opening of rubber gate top connection, secondary packing box 4 bottoms are threaded with the rubber gate top connection, central part at the secondary packing box is provided with the sealer 2 that two ends are convex arc surface, and the upper and lower side at sealer 2 is provided with concaved circular cambered surface adjustment seat 3, the top of secondary packing box 4 is provided with the pressure cap 1 be threaded.
When application the utility model, the production tee junction of the lower contact of rubber gate 7 and production tree is connected, polished rod is passed to this device to be connected with the sucker rod roofbolt in well, then with the polished rod eye of oil pumper, connect, shut rubber gate, add the upper level packing, press the packing pressure pad, load onto secondary packing box body, the secondary packing will be loaded onto in sealer, regulator base is loaded onto in top and bottom at sealer 2, load onto pressure cap 1, first rotate the secondary packing box, regulate and the tightness of packing, rotate again pressure cap 1, elasticity between the good sealer of appropriate regulation and adjustment seat, open rubber gate 7, starting oil pumper starts to recover the oil, but adjustment seat 3 and sealer 2 coordinate the concentricity of appropriate regulation polished rod and well head, the print cartridge of minimizing to packing, make well head oil-proof, while changing the one-level packing, must propose packing pressure pad 5 with special tool, otherwise just can not trip out the one-level packing, this kind design is mainly to prevent that the lawless person from stealing oil at the packing box place.
