Technical field
This utility model relates to Thread check detecting instrument technical field, seals particularly to special thread oil casing female thread
Surface depth measurer.
Background technology
The relatively gap of the pipe screw product of China and external industrially developed country, maximum gap is exactly crudy.
Want to improve pipe screw processing quality it is necessary to ensure that screw thread parameters mismachining tolerance controls in product predetermined tolerance, and to the greatest extent
Error may be made less.This just requires that we, except there to be the process technology of advanced person, also to possess the thread single parameter of advanced person
Measuring instrument and method.
At present in OCTG industry, it is former due to pipe poor quality etc. for having 3%-5% in beaten Oil/gas Well
Because of scrapping of causing, wherein the tubing of about 80% all occurs in threaded connection place.This is due to the spiral shell of oil pipe thread joint
Stricture of vagina crudy is poor, and each individual event parameter of screw thread does not arrive technology requirement, causes pipe bonding strength and sealing to meet not
Use requirement.
Special thread oil casing is widely used in the Development and Production of Oil/gas Well, and it is during processing and manufacturing, for improving
Sealing effectiveness after connection, need to measure the sealing surface degree of depth of its female thread junction, existing measurement special buckle oil jacket
The technology of the pipe thread seal face degree of depth is to use vernier depth gage to measure, and the position of measurement is for approximating its shoulder apex, no
Can accurately measure the degree of depth of its actual sealing surface, cause machining accuracy not high enough, have a strong impact on product quality.For another example patent
Number it is ZL201320805241.4 Chinese utility model patent, although it can measure the degree of depth of actual sealing surface, but from its knot
There are some drawbacks on structure: first, during its design basis face, substantially use the design of the symmetrical type of conventional depth chi
Principle, during use, the hands of operator datum level to be pinned side makes that it overlaps end surfaces and opposite side is unsettled, dip stick to be kept
Guarantee measured value parallel with tube axis is accurate, but because opposite side is unsettled, necessarily cannot ensure dip stick and tube axis
Parallel；The most just cannot ensure to measure accurately；Secondly, it uses electronic digital display form, though can direct-reading, but affect the environment of indicating value because of
Element is the most, and the such as gratings strips in the bigger area of Temperature Difference Ratio or digital display rule has a stain etc. and all can affect indicating accuracy's practicality
Poor.
