Problems solved by technology

The rapid repair of the pipeline system is an urgent problem to be solved, and the connection methods and connectors of the pipeline are also increasing. The common welding has the following shortcomings: 1. It is easy to be limited by the material. Welding process; 2. Welding is prone to large heat-melt deformation and stress, resulting in damage or even cracks in the pipeline; 3. Low sealing performance and poor leak-proof performance; 4. Special welding equipment is required, which is not conducive to on-site construction
There are following deficiencies in threaded connection: 1. It is difficult to process threads, especially for thin-walled metal pipes, plastic pipes and metal-plastic composite pipes; 2. After processing threads such as thin-walled metal pipes, plastic pipes and metal-plastic composite pipes , the strength is obviously reduced; 3, the sealing effect is poor, and

Abstract

The invention discloses a pipeline quick service sleeve joint, wherein two sealing rings and one pair of tapered claws are respectively sleeved on pipe mouths of connected pipes and arranged in tapered holes of a locking sleeve, the taper of the outer tapered surfaces of the claws is matched with the taper of the tapered holes of the locking sleeve, inner holes of the claws are matched with outer diameters of the connected pipes, a sealing cushion is arranged at a place where pipe mouths of the two connected pipes are abutted, and is clamped by the pair of claws, and a clamping member is arranged on the locking sleeve. The locking sleeve is of a cylinder structure, one end of the locking sleeve, which is far away from the pipe mouths, is provided with a cone chamfer; and the clamping member comprises two clamps with inner taper cavities, the taper of the inner taper cavities of the hoops is matched with the taper of the taper chamfer, and the two clamps are connected through a bolt. The sleeve joint has the advantages of reasonable structure, good sealing property, high connection strength, simpleness in manufacture, and convenience and rapidness in installation and maintenance.
