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 approach each other and move, 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, a pressing ring 50 sleeved on the pipeline 1 to be connected is arranged between the locking ring 30 and the elastic sealing ring 40, two ends of the pressing ring 50 are respectively abutted against the locking ring 30 and the elastic sealing ring 40, the connecting sleeve 10 and the pressing sleeve 20 are connected through a screw rod 70, the pressing ring 50 is connected with the screw rod 70 to form axial limiting, and a locking nut 71 is arranged on the opposite side of the connecting sleeve 10 and the pressing sleeve 20.
In the scheme, when the connecting sleeve is installed, the locking nut 71 on one side of the connecting sleeve 10 is firstly tightened to drive the pressing sleeve 20 and the pressing ring 50 to move towards the connecting sleeve 10, the distance between the pressing ring 50 and the connecting sleeve 10 is shortened, at the moment, the pressing ring 50 can press the elastic sealing ring 40 towards the connecting sleeve 10, the distance between the pressing ring 50 and the connecting sleeve 10 is unchanged, and the locking ring 30 cannot be prevented from pressing the elastic sealing ring 40 by the locking limit. The sealing of the product can be ensured firstly by the one-step installation, when the part is tightened and the sealing element is completely sealed, the nut 71 at the position of the gland 20 is tightened again to drive the pressing sleeve 20 to displace towards the pressing ring 50, at the moment, the gland 20 can press the locking ring 30 to enable the locking ring 30 to lock the pipeline 10, and then the sealing and the locking of the locking ring 30 are tightened twice. The locking action between the two is prevented from interfering with each other to influence the integral assembly. In the whole process, only the pressing sleeve 20 and the pressing ring 50 which are light in weight are driven, so that the difficulty of installation work and the stress degree of the connecting piece are reduced.
The pressing ring 50 is in threaded connection with the screw 70. Therefore, the compression ring 50 and the screw rod 70 can be conveniently disassembled, transported and assembled, and the length of the screw rod 70 can be conveniently adjusted and replaced to adapt to pipelines with various sizes.
The connecting lugs 51 are uniformly arranged on the outer ring of the pressing ring 50 at intervals in the circumferential direction, the connecting lugs 51 are provided with rotation stopping counter bores 53 for containing limiting nuts 52, and the limiting nuts 52 are in threaded connection with the screw rods 70. When the pressure ring is manufactured, the connecting lug 51 and the rotation stopping counter bore 53 can be directly cast in an integrated mode on the outer ring of the pressure ring 50, tapping is not needed, and only the limiting nut 52 needs to be placed in the rotation stopping counter bore 53, so that the manufacturing process and manufacturing cost of the pressure ring 50 are reduced.
The anti-rotation counterbore 53 opens toward the pressing sleeve 20. Since the compression ring 50 is displaced towards the connection sleeve 10 in the whole locking process of the nut 71, the limit nut 52 and the compression ring 50 must form a limit in the opposite direction, and the limit nut 52 is put into the rotation stopping counter bore 53 from the opening of the rotation stopping counter bore 53, so that the opening of the rotation stopping counter bore 53 faces towards the compression sleeve 20.
Annular cavities for containing the locking ring 30 and the elastic sealing ring 40 are respectively formed between the inner rings of the adjacent sides of the pressure sleeve 20 and the connecting sleeve 10 and the outer wall of the pipeline 1 to be connected, 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.
