Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1 to 6.

When remote heat supply, traditional pipe connection is only through flange or clamp connection, sealed effect is limited, for increasing sealed effect, the event is equipped with sealing device, when carrying out left pipeline 1 and right pipeline 2's connection, make left flange 3 and flange butt joint, and make connecting hole 7 on the left flange 3 and the connecting hole 7 one-to-one back on the right flange 5, fasten through bolt fit connecting hole 7, left flange 3 makes flange 6 can insert ring channel 4 just with the butt joint of right flange 5, ring channel 4 has certain tapering, after flange 6 and ring channel 4 cooperation, it is effectual to compress tightly between flange 6 and the ring channel 4 contact surface, the leakproofness is higher, cooperation seal ring 14 can further increase sealed effect.

In the process of long-distance heat supply, because the length of the pipeline is long, certain buckling deformation is easy to generate due to self reasons, in addition, certain settlement change and other reasons can also occur on the terrain, the pipeline is easy to deform, particularly, the joint of the two pipelines is easy to be influenced by the deformation, the stability of heat supply is influenced, in order to resist the influence, an anti-deformation device is arranged at the joint of the two pipelines, and the yield strength of the stress pull rod 12 is smaller than that of the tensile spring 13; when the pipeline generates stress which can deform the joint of the left pipeline 1 and the right pipeline 2 due to self reasons or external factors, when the stress is small, the stress pull rod 12 cannot reach the yield strength, can resist the stress and prevent the joint of the two pipelines from deforming; when the stress is increased, the stress pull rod 12 reaches the yield strength, and the tensile spring 13 does not reach the yield strength, at the moment, the stress pull rod 12 fails, and the tensile spring 13 can resist the stress, so that the deformation of the joint of the two pipelines is prevented; when the stress continues to increase and exceeds the yield strength of the tensile spring 13, the tensile spring 13 fails, and at this time, the whole tensile screw 11 fails, and the deformation-resistant device cannot resist the deformation force, and the deformation force acts on the joint of the two pipelines, so that the joint is correspondingly changed.

The two upper supporting plates 9 and the two lower supporting plates 8 are symmetrically arranged, the tensile assembly on the upper side and the tensile assembly on the lower side are symmetrically arranged, so that the deformation resistance effect is remarkable, and the tensile screw 11 penetrates through the counter-pulling hole 10 and is fastened through a nut, so that the rigidity is good; a plurality of left reinforcing ribs 15 fixedly connected with the left flange 3 are uniformly distributed on the left pipeline 1 along the circumferential direction, so that the strength of the left flange 3 can be increased, and a plurality of right reinforcing ribs 16 fixedly connected with the right flange 5 are uniformly distributed on the right pipeline 2 along the circumferential direction, so that the strength of the right flange 5 can be increased; left pipeline 1 and right pipeline 2 are the insulating tube, guarantee that the heat can stable transmission in the pipeline.
