In a further technical scheme, a groove communicated with the seam allowance is formed in the end, close to the welding ring, of the flange plate, so that the interference of welding seams of the welding ring can be avoided, the welding ring is guaranteed to be tightly attached to the flange plate, and the flange is stressed uniformly.
In a further technical scheme, the flange plate is made of carbon steel, and the carbon steel has high tensile strength and can effectively prevent the flange plate from deforming.
The utility model has the advantages that:
1. the material of the flange plate can be changed at will by arranging the loose flange on the pipeline, and other materials with low cost and high deformation resistance can be selected as the deformation-resistant material, so that the local deformation of the flange caused by the gravity action and the thermal expansion of the pump is prevented, and the installation stability is improved;
2. the joint surface of the flange plate and the welding ring is provided with the seam allowance, so that the joint of the flange plate and the welding ring can be positioned, and the operation of the pump is prevented from being influenced by installation deviation;
3. the flange plate and the pipeline and the welding ring are in clearance fit, so that the convenience of assembling and disassembling the flange plate can be improved, and the flange plate is easy to replace;
4. the inner ring of the welding ring is provided with welding grooves which respectively extend to two end faces of the welding ring, so that the welding seam can be prevented from interfering the connection of the pipeline, and the interference of the joint of the welding ring and the flange plate can be avoided;
5. the port of the flange plate close to the welding ring is provided with a groove communicated with the seam allowance, so that the interference of the welding seam of the welding ring can be avoided, the welding ring is ensured to be tightly attached to the flange plate, and the stress of the flange is uniform.
