Detailed Description

A pipeline connector comprises a connecting sleeve 10 and a pressing sleeve 20 which are sleeved on a pipeline 1 to be connected, wherein the connecting sleeve 10 and the pressing sleeve 20 form a connection fit for limiting the axial separation of the connecting sleeve 10 and the pressing sleeve 20, a locking ring 30 and an elastic sealing ring 40 are sleeved on the pipeline 1 to be connected at the joint of the pressing sleeve 20 and the connecting sleeve 10, the locking ring 30 and the elastic sealing ring 40 form mutual axial extrusion fit and radial deformation when the pressing sleeve 20 and the connecting sleeve 10 are close to each other and move, and one end, far away from the pressing sleeve 20, of the connecting sleeve 10 is connected with a pipeline connecting piece or a pipeline part.

Above-mentioned scheme is through realizing locking and sealing function respectively, then remain corresponding check ring 30 or elastic seal ring 40 to the pipe connection that only need lock or sealing function, the utility model discloses well preferred check ring 30 and elastic seal ring 40 that set up jointly. Thereby realize the radial deformation of locking ring 30 and elastic seal ring 40 through the mutual formula displacement of connecting sleeve 10 and pressure sleeve 20, thereby reach the effect of locking fixed and sealed, locking and fixed constitute by different parts and can realize its function better, the pipe connection spare generally is flange, can treat the terminal surface of connecting pipe 1 at two and set up this connector rethread flange and connect each other, as shown in figure 12, 13, 14, 15, 16, 17, the connecting sleeve 10 in this application also can directly set up on pipeline spare part such as elbow, tee bend, valve, hough section, pipe strap, can reduce the quantity of connecting piece like this. As shown in fig. 17, the connecting sleeve 10 itself can be a reducer pipe for connecting two pipes with different pipe diameters.

Annular cavities for containing the locking ring 30 and the elastic sealing ring 40 are formed between the inner rings of the pressure sleeve 20 and the adjacent side of the connecting sleeve 10 and the outer wall of the pipe to be connected 1 respectively, a pressing ring 50 sleeved on the pipe to be connected 1 is arranged between the locking ring 30 and the elastic sealing ring 40, and two ends of the pressing ring 50 are inserted into the annular cavities. The locking ring 30 and the elastic sealing ring 40 are positioned radially through the annular cavity, so that the locking ring 30 and the elastic sealing ring 40 are prevented from expanding outwards and being crushed too much in the extrusion process. Meanwhile, the closed environment is favorable for improving the extrusion force to enhance the sealing and locking effects, and in addition, the locking ring 30 and the elastic sealing ring 40 are positioned in the annular cavity to avoid aging and rusting of the annular cavity, so that the service life of the annular cavity is prolonged.

The inner rings of the adjacent sides of the pressing sleeve 20 and the connecting sleeve 10 are in a bell mouth shape with large adjacent end and small departing end, the outer ring contour of the locking ring 30 is in line with the inner ring contour of the pressing sleeve 20, and the outer ring contour of the elastic sealing ring 40 is in line with the inner ring contour of the pressing sleeve 20. The flared shape essentially forms a guiding step to convert the axial pressing force of the pressing sleeve 20 and the connecting sleeve 10 approaching each other to the locking ring 30 and the elastic sealing ring 40 into a radial pressing force, so as to drive the locking ring 30 and the elastic sealing ring 40 to deform radially.

And annular frustum 11 for guiding two ends of the compression ring 50 is arranged at the cavity opening of the annular cavity of the connecting sleeve 10. Because of the dimensional tolerance, a certain gap generally exists between the pressing ring 50 and the pipeline 1 to be connected, under the action of gravity, the pressing ring 50, the pressing sleeve 20 and the connecting sleeve 10 are eccentric, at the moment, the annular frustum 11 is required to guide the pressing ring to the correct position, the annular cavity of the pressing sleeve 20 can also be provided with the structure, and only because the locking ring 30 is generally a metal piece, the outer diameter of the pressing ring 50 on the side can be designed to be smaller so as to be conveniently inserted into the annular cavity and abut against the locking ring 30.

The periphery of the compression ring 50 is provided with an annular abutting step 51 for abutting against the compression sleeve 20, and is further provided with an annular limiting step 52 forming axial limiting with the connecting sleeve 10. For a pipe that does not need to be locked and fixed, the locking ring 30 can be removed and the pressing sleeve 20 can directly press the pressing ring 50, and meanwhile, the pressing ring 50 is prevented from being pressed too deeply to crush the elastic sealing ring 40.

The locking ring 30 is a C-shaped metal ring. A constricted space for the locking ring 30 is reserved.

The locking teeth 31 are uniformly arranged on the inner ring of the locking ring 30 at intervals in the circumferential direction, notches 32 are formed in the positions, corresponding to the locking teeth 31, of the outer ring of the locking ring, and the arc length occupied by the notches 32 is smaller than that occupied by the locking teeth 31. The locking ring 30 of being convenient for like this contracts, guarantees simultaneously that each section of locking ring 30 is comparatively even, and the arc length setting of breach 32 has guaranteed that locking tooth 31 possesses sufficient extrusion locking force, also can set up to breach 32 dodge locking tooth 31, and locking force is stronger like this, and the degree of consistency is lower.

One side of the pressing sleeve 20, which is far away from the connecting sleeve 10, is provided with locking bolts 21, the axial direction of which is located in the radial direction of the pressing sleeve 20, the locking bolts 21 are evenly arranged in the axial direction of the pressing sleeve 20 at intervals, and the locking bolts 21 radially lock the pipeline 1 to be connected. Further locking and fixing double anti-dropping. Fig. 5 shows a double anti-slip press sleeve 20 structure, and fig. 6 shows a single anti-slip press sleeve 20 structure

The locking bolt 21 is provided with a locknut 22. The locking bolt 21 is prevented from loosening and falling off.

The tail part of the locking bolt 21 abuts against the periphery of the locking ring 60, the locking ring 60 is sleeved on the pipeline 1 to be connected, a positioning groove 61 for accommodating the tail part of the locking bolt 21 is formed in the periphery of the locking ring 60, and anti-falling teeth 62 for clamping and fixing the pipeline 1 to be connected are arranged on the inner ring of the locking ring 60. Further enhancing the anti-slip capability and preventing the capture ring 60 from disengaging from the capture bolt 21.

The position locking ring 60 is formed by two semicircular rings in an enclosing mode. Is convenient to install and use.

The connecting sleeve 10 and the pressing sleeve 20 are connected through a square neck bolt 70, square holes are formed in the connecting sleeve 10 and the pressing sleeve 20 corresponding to the square neck bolt 70, and a locking nut 71 of the square neck bolt 70 is located on one side far away from the connecting sleeve 10. Since there are flange, valve, etc. on one side of the connecting sleeve 10, the space is small and it is not convenient for wrench operation, so that the locking nut 71 is placed on one side of the pressing sleeve 20 to lock the bolt in a large space.

As shown in fig. 18 and 19, the internal thread provided on the inner ring of the pressing sleeve 20 is in threaded connection with the external thread on the outer ring of one end of the connecting sleeve 10. Therefore, the internal parts can be completely wrapped, and the internal parts are prevented from rusting or aging.
