Detailed description of the invention
Understand for technical characterictic of the present utility model, object and effect being had more clearly, now contrast brief description of the drawings detailed description of the invention of the present utility model:
Fig. 1 is the composition structural representation of the oily device of anti-race during for rod parting of the present utility model.Fig. 2 is the top view of seal rubber plug in the utility model, and in figure shown in dotted line is sucker rod.Fig. 3 is the front view of the outer end of adjusting rod in the utility model.
Referring to Fig. 1, the utility model proposes for rod parting time the oily device of anti-race, include a body 1, a ring joint 2, a side joint section 3 and an elastic packing portion 4, wherein:
On described body 1, along the vertical pilot hole 11 wearing for sucker rod that is provided with, the internal diameter of described pilot hole 11 and the external diameter of described sucker rod match;
Described ring joint 2 is connected on the bottom of described body 1, the internal face of described ring joint 2 is provided with screw thread 21, in it, ring cavity is communicated with described pilot hole 11, and be coaxial setting, in the time that reality is used, by ring joint is set, be convenient to body be connected to well head other device (on packing box), be beneficial to use;
Described side joint section 3 is horizontal positioned, its the inner is connected on the sidewall of described body 1 one sides, the interior along continuous straight runs of described side joint section 3 is provided with a gathering sill 31, the inner of described gathering sill 31 is connected with described pilot hole 11, its external port is positioned at the outer face place of described side joint section 3, and is connected with an adjusting rod 32 by internal thread;
Described elastic packing portion 4, mobile being embedded in described gathering sill 31, its outer end correspondence is connected on the inner face of described adjusting rod 32, its inner can corresponding shutoff described in pilot hole 11.
Be preferred embodiment, described elastic packing portion 4 includes a seal rubber plug 41 and a Compress Spring 42, described seal rubber plug 41 and Compress Spring 42 are placed in described gathering sill 31 from the inside to the outside successively, the sidewall of described seal rubber plug 41 is mutually closely connected with described gathering sill 31, pilot hole 11 described in the corresponding shutoff of its inner energy, the two ends correspondence of described Compress Spring 42 is connected to the outer end of described seal rubber plug 41 and the inner face of described adjusting rod 32.
As shown in Figure 1, be separately provided with the groove 12 of an energy accommodating described seal rubber plug the inner on the sidewall of described pilot hole 11, described groove 12 is and is oppositely arranged with the inner of described gathering sill 31, and the inner of its shape and described seal rubber plug 41 matches.In the time of concrete application, seal rubber plug 41, under the elastic force effect of Compress Spring 42, can protrude out in groove 12, improves the sealing effectiveness to pilot hole 11.
Please also refer to Fig. 2, the inner face of described seal rubber plug 41 is separately concaved with a caulking groove 411 matching with the lateral surface of described sucker rod.In the time that sucker rod is arranged in pilot hole, caulking groove 411 can corresponding be fitted in the external surface of sucker rod, the remaining fluid on sucker rod can be scraped, and prevents that crude oil from being taken out of outside well, and then pollutes well head;
Further, the sidewall of described body 1 opposite side is provided with apical pore 13, and described apical pore 13 is corresponding to be connected with the bottom land of described groove 12.In the time that sucker rod is normally worked, this apical pore 13, in sealing state, can effectively be prevented to crude oil overflows; When rod parting and seal rubber plug 41 enter after groove 12 under 42 effects of contracting spring, reinstalling in sucker rod process, seal rubber plug is ejected through apical pore by normal screws cutter, so that sucker rod is mounted in pilot hole 11.
As shown in Figure 3, the outer end of preferred described adjusting rod 32 is hexagonal prism shape, can coordinate with instruments such as spanners more easily.While work at the scene, in the time that the inner of seal rubber plug is resisted against sucker rod, or, after seal rubber plug shutoff pilot hole, can need to be towards gathering sill inner side or outside precession adjusting rod according to using, further to regulate the position of seal rubber plug, to improve result of use.
In addition, for more convenient manufacture, improve overall construction intensity, preferred described body 1, ring joint 2 and side joint section 3 are formed in one.And above-mentioned body, ring joint and side joint section also can be formed from steel, and body, side joint section are substantially in tubular construction.
The utility model proposes for rod parting time the oily device of anti-race, in the time of work, be connected on wellhead assembly (such as packing box) by ring joint 3, make sucker rod 5 correspondences be arranged in pilot hole 11, and the inner of seal rubber plug 41 is under the effect of Compress Spring 42, fit in the lateral surface place of sucker rod 5, it is worth mentioning that, for ease of assembling, can first be about to sucker rod 5 is arranged in pilot hole 11, in gathering sill 31, pack seal rubber plug 41 into more subsequently, Compress Spring 42 and adjusting rod 32, and according to seal rubber plug 41 situation that coordinates with sucker rod, further adjust adjusting rod, to reach best effect.
In the time that sucker rod is normally worked, the utility model is only fitted in the lateral surface of sucker rod 5 by seal rubber plug 41, so that the remaining fluid on sucker rod is scraped, prevents that crude oil from being taken out of outside well; Once disconnected de-when sucker rod, in the time that disconnected de-sucker rod leaves pilot hole 11, seal rubber plug 41, under the effect of Compress Spring 42, enters and shutoff pilot hole 11, realizes the automatic-sealed to well head, thereby avoids well head to run oil, causes pollution in wide area.
The foregoing is only the schematic detailed description of the invention of the utility model, not in order to limit scope of the present utility model.Any those skilled in the art, is not departing from equivalent variations and the amendment under the prerequisite of design of the present utility model and principle, done, all should belong to the scope of the utility model protection.
