Abstract
The utility model pertains to the pipeline sealing connection structure sealing detection technologies, and specifically discloses a coupling cone-shape sealing depth measuring dialgage. The coupling cone-shape sealing depth measuring dialgage comprises a positioning cross beam, and a dial plate which is installed on one side of the positioning cross beam. The coupling cone-shape sealing depth measuring dialgage further comprises a straight connecting rod which is located on the other side of the positioning cross beam, wherein the straight connecting rod is connected with a bevelling connecting rod, and the bevelling connecting rod is provided with a spherical contact. According to the utility model, by adopting the positioning cross beam as the positioning reference, the cumbersome step in which adjustment is performed according to different coupling specifications can be avoided, and the accuracy of the measurement result can be improved at the same time. The contact is designed into a spherical contact and is tangent to two side surfaces of a standard sample piece groove, so the precision of the measurement can be ensured.
Description
Technical field
The utility model belongs to seal for pipe joints syndeton sealing detection technology, is specifically related to a kind of dial gauge of the box cupling cone seal depth survey that connects for the Oil/gas Well oil pipe.
Background technology
The air-tight structure processing of petroleum casing pipe and oil pipe is the committed step that oil country tubular goods is made.As shown in Figure 1, box cupling 1 is the tubular construction of the both ends open of symmetry, and end face 4 openings, cylindrical sidewall are diconical sealing surface 2, and the sealing surface 2 at box cupling 1 center is processed with torque shoulder 3 with the junction of tubular bottom.Above-mentioned box cupling 1 forms the air-tight seal connecting structure of so-called petroleum casing pipe and oil pipe.Wherein, the measurement of diconical sealing surface 2 degree of depth of the box cupling of this syndeton is key links of check.Because the sealing surface 2 of needs measurement hermetically-sealed construction and the cross section of passing through the tubing axis of torque shoulder 3 are V-shaped narrow grooves, can't measure with general general measurer.
So extremely be necessary to solve by a kind of effective measurer the problem of petroleum casing pipe and the inconvenience of oil pipe hermetic seal structure box cupling bevelled sealing surface depth detection.
Summary of the invention
The purpose of this utility model is to provide a kind of box cupling cone seal depth survey dial gauge rational in infrastructure, easy and simple to handle, reaches the purpose that the sealing surface of the box cupling that the Oil/gas Well oil pipe is connected detects.
The technical solution of the utility model is as follows:
A kind of box cupling cone seal depth survey dial gauge, it comprises location crossbeam and the dial plate that is installed in location crossbeam one side, also comprises the straight connecting rod of location crossbeam opposite side, and straight connecting rod is connected with the knuckle connecting rod, and described knuckle connecting rod is provided with spherical contact.
In above-mentioned box cupling cone seal depth survey dial gauge: the interior angle of described knuckle connecting rod is that 120 degree are to 160 degree.
Remarkable result of the present utility model is: the utility model adopts the location crossbeam as positioning datum, has avoided different according to the box cupling specification and loaded down with trivial details step that need to adjust, has increased simultaneously the accuracy of measurement result; Contact is designed to sphere, and is tangent with two sides of standard sample sample groove.Guarantee the degree of accuracy of measurement.

Fig. 3 is box cupling cone seal depth survey dial gauge structural representation of the present utility model;
Fig. 4 is box cupling cone seal depth survey dial gauge measurement standard sample piece synoptic diagram of the present utility model;
Among the figure: 1. box cupling; 2. sealing surface; 3. torque shoulder; 4. coupling face; 5. dial plate; 6. location crossbeam; 7. direct-connected extension bar; 8. knuckle connecting rod; 9. interior angle; 10. spherical contact; 11. standard sample; 12. sample groove.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 2, standard sample 11 be one with end plate closes the cylinder of one end, be processed with sample groove 12 at bottom of cylinder.This sample groove 12 is identical with the narrow groove size that sealing surface 2 and torque shoulder 3 form.
As shown in Figure 3, dial plate 5 is placed an end of location crossbeam 6, and pass through screw-driving.Straight connecting rod 7 of other end fixed installation of location crossbeam 6, an end of straight connecting rod 7 is connected to an end of knuckle connecting rod 8, and the other end of described knuckle connecting rod 8 is equipped with spherical contact 10.The interior angle 9 that has shown the knuckle connecting link of above-mentioned knuckle connecting rod 8 among Fig. 3.Interior angle 9 is chosen as 150 degree in this enforcement.
During measurement, as shown in Figure 4, elder generation's table of corrections dish 5 on standard sample 11, and with its reading zero setting, location crossbeam 6 is adjacent to the end face 4 of box cupling 1.Then the spherical contact 10 of an end of knuckle connecting rod 8 is put in the sample groove 12 in the standard sample 11.Because knuckle connecting rod 8 has interior angle 9, can bend,, protruding into narrow sample piece 11 by direct-connected extension bar 7, the degree of depth of the bevelled sealing surface 2 in the box cupling 1 can be measured in box cupling 1 inside in the syndeton of sample piece 11 imitations.
