Description

Technical Field

[0001] The utility model relates to the technical field of flat welding flanges, in particular to a high-performance plate-type flat welding flange. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects pipes to each other. It is used for connection between pipe ends. It is also used as flange on equipment inlet and outlet, used for connection between two equipment, such as reducer flange. Plate flat welding flange is widely used in chemical industry, construction, water supply, drainage, shipbuilding and other basic projects because of its convenient material acquisition, low cost and simple manufacturing.

[0003] Prior art, such as: CN217482218U is a high-performance plate-type flat-welded flange. Through the design of an annular seat, an inclined support rod, a sliding ring, an annular gear and a buffer spring, when the flange main plate is subjected to horizontal impact force, the flange main plate drives the sliding ring to slide along the pipe inside the annular seat through the inclined support rod, and the buffer spring slows down the sliding of the sliding ring, thereby slowing down the horizontal impact force on the flange main plate and preventing the flange from bending and breaking; when one pipeline rotates with another pipeline through the flange main plate, the flange main plate rotates with the sliding ring inside the annular seat through the inclined support rod, and the annular gear of the sliding ring meshes with the teeth of the inner wall of the annular seat to prevent the sliding ring from rotating, thereby sharing the torque on the welding point between the flange main plate and the pipeline, preventing the welding point between the flange and the pipeline from breaking, and improving the service life of the flange.

[0004] However, this device still has certain shortcomings when in use. When the flange body is subjected to horizontal impact force, it can only reduce the impact force in one direction, so that the flange is still subjected to impact force in another direction, which is easy to cause damage. In addition, the sealing effect in the pipeline is relatively poor, and leakage is prone to occur at the connection between the two pipes.

[0005] Therefore, a high-performance plate-type flat-welded flange is proposed to address the above problems. Utility Model Content
