Abstract
The utility model discloses a proofreading block used for height detection of an oil sleeve joint premium connection. The proofreading block is provided with two planes with a height difference. The height difference is consistent with a height difference formed between adjacent screw tooth top faces of a standard premium connection. The height difference refers to a groove arranged on the proofreading block. One boss top face on one side of the groove is higher than another boss top face on the other side of the groove. The two boss top faces are facing toward the same direction. The proofreading block is especially used for a premium connection structure, wherein a thread height extension line is perpendicular to an oil sleeve axis. The proofreading block matches a detector which adapts to the premium connection for accurate detection. Moreover, the proofreading block is convenient and practical, highly targeted, simple in structure, accurate in proofreading, etc.
Description
Technical field
The utility model relates to proof-reading block, specifically is a kind of proof-reading block that oil sleeve joint special thread tooth depth detects that is used for, and it is used with " oil sleeve joint special thread tooth depth detector ".
Background technology
The oil sleeve joint screw thread is divided into API screw thread and non-API screw thread.The API screw thread is produced according to the API code requirement; But not the API screw thread is also referred to as special thread (premium connection), and it is for satisfied harsh day by day oil gas well working condition, and one type of oil sleeve joint screw thread developing; This type screw threaded arrangement is at the tapered end of tubing and casing; Its arrangement has two kinds, and wherein a kind of with screw thread tooth depth and the perpendicular mode of tubing and casing end tapered face, each thread end face of this screw thread is in (referring to Fig. 3 and Fig. 4) on the same line; Another kind of with screw thread tooth depth extension line and the perpendicular mode of tubing and casing axis, each thread end face of this screw thread constitutes stairstepping, and certain altitude poor (referring to Fig. 1 and Fig. 2) is just all arranged between each thread end face.They are compared the API threaded connector and have higher strength of joint, gas tightness, torque resistant property, bending resistance, anticorrosion stress-resistant property and high temperature creep-resisting property.
In the special thread process of manufacture of oil sleeve joint, need carry out strict detection to each individual event parameter of special thread, these individual event parameter determining the quality of product, and for example tooth depth is important parameter wherein.For for the perpendicular special thread of screw thread tooth depth and tubing and casing end tapered face; Its thread high detection is accomplished through conventional API thread high detection appearance, be about to detector be placed on the corresponding to proof-reading block of standard thread tooth depth on, accomplish the benchmark zero clearing with this; To be placed on by the good detector of check and correction then and be in collinear adjacent thread end face; The gauge head of dial gauge touches the end, can obtain product mismachining tolerance value through the numerical value that shows on the dial gauge, judges whether product is qualified.And for for the perpendicular special thread of screw thread tooth depth extension line and tubing and casing axis; Because structural difference; Conventional API thread high detection appearance at all can't testing product the mismachining tolerance value; Extremely inapplicable, carry out the improved while at thread high detection appearance and also be badly in need of and will improve, so that carry out supporting use with special thread tooth depth detector after improving with the proof-reading block that detector matches.
Summary of the invention
The purpose of the utility model is: be directed against with screw thread tooth depth extension line and the perpendicular special thread structure of tubing and casing axis; Tooth depth detector to this special thread carries out the improved while; A kind of proof-reading block that oil sleeve joint special thread tooth depth detects that is used for is provided so that with the supporting use of detector.
The technical scheme that the utility model adopts is: a kind of proof-reading block that is used for the detection of oil sleeve joint special thread tooth depth; Have two planes that form difference in height on the said proof-reading block, the difference in height that forms between the adjacent thread end face of this difference in height and standard special thread is consistent; Said difference in height is on proof-reading block, to be provided with a groove, and a side boss end face of groove is higher than opposite side boss end face, two boss end faces identical towards face.
Said proof-reading block has center pit.
The beneficial effect of the utility model is: the proof-reading block of said structure is directed against with screw thread tooth depth extension line and the perpendicular special thread structure of tubing and casing axis specially; Match with the tooth depth detector that adapts to this special thread; Realize accurately detecting, it has characteristics such as simple in structure, convenient and practical, that check and correction is accurate and with strong points.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is existing a kind of oil sleeve joint special thread structural representation.
Fig. 2 is the enlarged drawing of local A among Fig. 1.
Fig. 3 is existing another kind of oil sleeve joint special thread structural representation.
Fig. 4 is the enlarged drawing of local B among Fig. 3.
Fig. 5 is a kind of structural representation of the utility model.
Code name implication among the figure: 1-proof-reading block; 2-center pit; 3,5-boss end face; 4-groove.
Embodiment
Referring to Fig. 5: a kind ofly be used for the proof-reading block that oil sleeve joint special thread tooth depth detects; The appearance profile of proof-reading block 1 is the tetragonal body structure substantially; Each face center is provided with a groove 4 around tetragonal body; One side boss end face 3 of groove 4 is higher than 5, two boss end faces of opposite side boss end face and is smooth shiny surface, and it is poor to form certain height between two boss end faces; The difference in height that forms between the adjacent thread end face of this difference in height and standard special thread is consistent, described standard special thread be meant satisfy the standard design value with screw thread tooth depth extension line and the perpendicular special thread of tubing and casing axis.
Hold use for ease, be provided with center pit 2 at the center of proof-reading block 1.
Claims (2)
1. one kind is used for the proof-reading block that oil sleeve joint special thread tooth depth detects, and it is characterized in that, has two planes that form difference in height on the said proof-reading block (1), and the difference in height that forms between the adjacent thread end face of this difference in height and standard special thread is consistent; Said difference in height is on proof-reading block (1), to be provided with a groove (4), and a side boss end face (3) of groove (4) is higher than opposite side boss end face (5), two boss end faces identical towards face.
2. according to the said proof-reading block that is used for the detection of oil sleeve joint special thread tooth depth of claim 1, it is characterized in that said proof-reading block (1) has center pit (2).
