Description

The pipe joint that is used for the connection traffic meter

Technical field

The utility model relates to and has securely the radially pipe adapter or the pipe fitting field of tightening member, is specially a kind of pipe joint that is used for the connection traffic meter.

Background technology

Flowmeter is to be connected in the pipeline instrument with real-time reflection pipeline inner fluid flow by joint and valve, and at present, flowmeter when adopting the mode that is threaded to be connected with pipeline, twine polytetrafluoroethylraw raw material band at the screw thread place in order to seal.This mode, because the helical pitch of screw thread promptly immobilizes after part processing is finished, and the length of screw thread energy precession also is constant, when like this flowmeter being connected with pipeline by screw thread, flowmeter from screw in beginning to screw in stop the back revolvable angle also fix, in actual the use, the formed angle of the final position of flowmeter and pipeline must satisfy the regulation requirement, such as, some flowmeter requirement, should be parallel after installing with pipeline, as shown in Figure 1, now need flowmeter 11 is fixed on the pipeline 12 by the mode that is threaded, require between final flowmeter 11 and the pipeline 12 parallel to each other, flowmeter 11 is so that 12 vertical initially beginning screw in pipeline, the initial position of flowmeter 11 and pipeline 12 is shown in two solid lines among Fig. 1, yet flowmeter 11 and pipeline 12 thread parameter have separately but determined normal condition down-off meter 11 to begin to screw in pipeline 12 vertical initial angles, to screwing in the angle that stops back and reference position is 60 °, and the position is the final position that flowmeter 11 screws in after stopping shown in double dot dash line among Fig. 1.In order to remedy 60 ° difference, perhaps shown in solid arrow among Fig. 1, make flowmeter 11 continue 120 ° of rotations by force, so very easily damaged screw and raw material band, reduction of service life; Perhaps shown in dotted arrow among Fig. 1, flowmeter 11 is circled round 60 °, make that like this raw material band that is wrapped on the screw thread is lax, easily cause leaking; The back of perhaps flowmeter 11 being circled round screws out, and twines again to adjust behind the raw material band to screw in initial angle and reconnect, owing to adjust angle entirely with artificial estimation, low precision often needs repeatedly to adjust, and not only greatly reduces operating efficiency, and having increased spillage of material, effect is also not satisfactory.
