Description
Technical field
The utility model relates to a kind of inner diameter measuring device, sealing cone diameter measuring device in especially a kind of threaded connector.
Background technology
Oil well pipe is the necessary oil country tubular good of recover petroleum and rock gas, up to a hundred oil well pipes are by being threaded, form a tubing string that reaches thousands of meters, tubing string need bear very big tensile load and internal fluid pressure, joint area is the weakest link, and it all is to occur in joint area that a lot of failure accidents are arranged.The hermetic seal joint that has superperformance has at present obtained application more and more widely, and this joint adopts the conical surface/conical surface seal structure, relies on the sealing property of the interference fit assurance joint of the conical surface and the conical surface.Therefore, the magnitude of interference of the conical surface and conical surface interference fit is very crucial, and the magnitude of interference is selected too small, and then the contact pressure of Pei Heing is low, and sealing ability is just poor, and the magnitude of interference is selected excessive, and the contact stress of cooperation is too high, can damage sealing surface again, influences its sealing property.Therefore, the radial interference amount of sealing cone is the important parameter that guarantees the joint sealing performance, also is one of major parameter that needs in producing strict check and control.
For the measurement of sealing cone in the special thread joint, the measurement mechanism that generally adopts comprises at present: a dial gauge and the cover calibrator unit that contact can stretch, and the precision machined calibration block of process, but its width is fixed bad adjusting.During use, measurement component is that two contacts of dial gauge are stuck in the centre of measuring calibration block, with the dial gauge zeroing, takes out dial gauge then after stablizing, and just can use it to measure the interior sealing cone of special thread joint.
The shortcoming of this measurement mechanism is:
1) according to the relevant industries standard, oil well pipe has a lot of different dimensions, from 23/8 " (60.3mm) to 133/8 " (339.7mm), even to 20 " (508mm); each specification all needs a calibrated bolck, so just need a lot of calibrated bolcks, increased the measurement cost; and so many calibrated bolcks, management is very inconvenient;
2) dial gauge need be put into together with the contact at two ends during this commercial measurement and measured the sealing surface diameter in the special thread joint internal thread,, not put in, cause and to measure with regard to there being enough spaces for the very little oil well pipe of diameter.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and it is the convenient and sealing cone diameter measuring device in the threaded connector accurately of continuity width and calibration that a kind of simple in structure, convenient management, calibration range are provided.
The technical scheme that provides according to the utility model, sealing cone diameter measuring device in the described threaded connector, be included in hard-wired fixed bar on the measurement bracket, the bottom of fixed bar is equipped with first measuring contacts, on measurement bracket, also slidely connect sliding bar, the top ends of sliding bar is equipped with dial gauge, the bottom of sliding bar is equipped with second measuring contacts, the sliding bar adjusting knob is installed on sliding bar, it is characterized in that: also be provided with the adjustable calibrating installation of measurement range, the adjustable calibrating installation of described measurement range is included in hard-wired stationary jaw on the calibrating jig, on calibrating jig, slidely connect the slip claw that cooperates with stationary jaw, all has the calibration conical surface that cooperatively interacts on stationary jaw and the slip claw, be provided with the adjusting knob of slip claw at calibrating jig, during calibration, the slip claw under the adjusting of adjusting knob near or away from stationary jaw.
Advantage of the present utility model is as follows:
1) reduced the quantity of calibration block, used calibrating jig to replace the calibration block of all size,, just can obtain the scale value of various needs by regulating the slip claw of reference component, more convenient to use;
2) scope of application of this measurement mechanism is wider, the fixed bar of measurement component and sliding bar can go deep into internal thread inside, and the dial gauge that volume is bigger is installed on the fixed bar, and dial gauge does not need to go deep into internal thread inside during the side amount, therefore, this measurement mechanism can detect the oil well pipe of all size.
