The utility model provides a run from opposite directions tetrafluoro cover connecting device, includes the sleeve, the connection pad is opened has the through-hole with sleeve external diameter looks adaptation, and the through-hole evenly sets up the bolt hole to the annular portion of outer circumference along circumference, sleeve one end is connected in the connection pad through-hole, and the terminal surface flushes with the connection pad upper surface.
Further, the sleeve is welded with the connecting disc.
Further, the sleeve and the connecting disc are of an integrated structure.
Further, the bolt hole spacing is 60-120 mm.
Further, the length of the sleeve is 0.5 to 0.7 times its outer diameter.
The tetrafluoro sleeve is simple and convenient to install, firm, not easy to wear and long in service life.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1-sleeve, 2-connecting disc, 3-bolt hole.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings.
As shown in the figure, the utility model provides a split tetrafluoro sleeve connecting device which comprises a sleeve 1 and a connecting disc 2, wherein the connecting disc 2 is provided with through holes matched with the outer diameter of the sleeve 1, bolt holes 3 are uniformly formed in the annular part from the through holes to the outer circumference along the circumferential direction, one end of the sleeve 1 is connected into the through holes of the connecting disc 2, and the end face of the sleeve is flush with the upper surface of the connecting disc.
Further, the sleeve 1 is welded with the connecting disc 2.
Further, the sleeve 1 and the connecting disc 2 are of an integral structure.
Further, the bolt holes 3 are spaced by 60-120 mm.
Further, the length of the sleeve 1 is 0.5 to 0.7 times its outer diameter.
When the steel pipe connecting structure is used, the polytetrafluoroethylene sleeve 1 is sleeved on a steel pipe, the connecting disc 2 faces upwards, the steel seat is attached to the connecting disc 2, the bolt hole 3 corresponds to the connecting hole in the steel seat, and the steel seat and the connecting hole are locked through a bolt.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the utility model.
