Abstract
The utility model discloses a polished rod sealing device of an oil pumping well, which comprises a packing box, a packing, a back cap, a spring and a deviation regulating device, wherein the deviation regulating device comprises deviation regulating deflection-prevention joints which are mutually connected, a ball head press cap, a ball head seal and a lower joint. The utility model is characterized in that the upper part of the packing box is connected with a main sealing body, and the lower part of the packing box is connected with the deviation regulating device; the main packing and the spare packing are arranged in the packing box; a press sleeve and a spacing hurdle are arranged between the packing box; the spring is arranged in the main sealing body and is arranged at the top end of the main packing; an inner cavity of the upper part of the main sealing body is provided with the packing and a press cap, and the top end is connected with a back cap. The utility model adopts four-stage sealing structure so as to improve sealing performance and prolong service life; after the utility model is fastened once without fastening again, and thus, the utility model has the advantages of low labor intensity, high time rate of well opening of the oil well and low manufacturing cost; the utility model prevents the occurrence of running, overflow, dripping, leakage and environmental pollution phenomenon, and is used for the manufacturing process of oil pumping.
Description
One, technical field
The utility model relates to sealing device, particularly a kind of pumpingh well polished rod sealer.
Two, background technology
Existing pumpingh well polish rod seal device is made of rubber valve, packing box and sealed packing, is installed on the mouth of pumped oil well, is the SLD of the essential routine of pumpingh well polished rod.But problem is the sealing device of this routine, because pumping and eccentric wear of polished rod, sealed packing in the packing box weares and teares easily, loses sealing function, has also had a strong impact on the application life of sealed packing, therefore, run, drip, leak and environmental pollution phenomenon owing to fastening untimely with replacing, usually take place in necessary directly often fastening and replacing packing, for heavy crude heat extraction and serious sand output well, leakage phenomenon is even more serious.Because fastening continually and replacing packing has increased labor intensity of operating personnel, has also increased cost of production simultaneously.
Three, summary of the invention
The purpose of this utility model provides a kind of improved pumpingh well polished rod sealer, shortcoming or deficiency that it can overcome effectively and avoid existing in the above-mentioned prior art, prolonged the application life of sealed packing greatly, alleviated labor intensity of operating personnel, also reduced cost of production simultaneously.
Pumpingh well polished rod sealer described in the utility model, comprise packing box, packing, back of the body cap, spring and deviation correcting device, described deviation correcting device comprises bias-proof joint, bulb pressure cap, bulb sealing and the lower contact that is coupled to each other, it is characterized in that described packing box top connects the primary seal body, the bottom connects deviation correcting device, install master root and standby packing in the packing box, install gland and jube therebetween, described spring is installed in the primary seal body, the master roots and tops, primary seal body top inner chamber is installed packing and pressure cap, and the top connects back of the body cap.
Wherein, described primary seal body is a tubulose upper and lower cavity structure, and cavity of resorption is provided with internal thread, is connected with packing box, and epicoele is provided with external screw thread, is connected with back of the body cap.Be provided with a bypass channel between the described primary seal body upper and lower cavity, this bypass channel is connected with UNICOM's joint that primary seal body opposite position is installed.Described bias-proof joint top is that tubulose, bottom are spheroid, and it forms the rotary seal pair with the ball seal of installing in the lower contact inner chamber.The inner surface of described bulb pressure cap mesopore is a spherical structure, matches with bias-proof joint top sphere, is connected in the lower contact upper end.
The utility model has following advantage compared with prior art:
1, adopts the level Four hermetically-sealed construction, improved sealing performance greatly, prolonged application life, can reach more than 1 year;
2, disposable need not be fastening once more after fastening, guaranteed the ordinary production of oil well, reduced labour intensity, rate when having improved the driving a well of oil well;
3, prevent the generation of run, drip, leak and environmental pollution phenomenon, reduced cost of production.
Four, description of drawings
Accompanying drawing is the utility model structural representation
Five, the specific embodiment
Referring to accompanying drawing, a kind of pumpingh well polished rod sealer, comprise packing box 8, packing 3,13,16, back of the body cap 1, spring 6 and deviation correcting device, deviation correcting device comprises the bias-proof joint 9 that is coupled to each other, bulb pressure cap 10, bulb sealing 11 and lower contact 12, packing box 8 tops connect primary seal body 5, the bottom connects deviation correcting device, install master root 16 and standby packing 13 in the packing box, install gland 14 and jube 7 therebetween, spring 6 is installed in primary seal body 5, and an end contacts with the lower surface of bypass channel 17, and the other end contacts with master root 16 tops, primary seal body 5 top inner chambers are installed packing 3 and pressure cap 2, and the top connects back of the body cap 1.
Primary seal body 5 is a tubulose upper and lower cavity structure, and cavity of resorption is provided with internal thread, is connected with packing box 8, and epicoele is provided with external screw thread, is connected with back of the body cap 1.Be provided with a bypass channel 17 between primary seal body 5 upper and lower cavities, this bypass channel 17 is connected with UNICOM's joint 4 that primary seal body 5 opposite positions are installed.Bias-proof joint 9 tops are that tubulose, bottom are spheroid, and it forms the rotary seal pair with the ball seal of installing in lower contact 12 inner chambers 11.The inner surface of bulb pressure cap 10 mesopores is a spherical structure, matches with bias-proof joint top sphere, is connected in lower contact 12 upper ends, and compacting bias-proof joint 9 closely cooperates itself and ball seal 11.During ordinary production, packing box 8 is not fastening with being connected of bias-proof joint 9, but reserves certain space, makes standby packing 13 be in stand-by state, and is only when changing master root 16, just that it is fastening, after replacing finishes, it unclamped again.Standby packing 13 and gland 14 also can play centralizing function.Seal 15 is installed in gland 14 upper ends.
