The invention discloses a connecting pipe joint component, in particular an equal-inner-diameter connecting pipe joint component. The connecting pipe joint component comprises a push part coating a first connecting pipe, a first spinning connecting piece coating the pipe end of the first connecting pipe, and a second spinning connecting piece coating the pipe end of a second connecting pipe, wherein the outer wall of the first connecting pipe is connected with the first spinning connecting piece through a mode of spinning from inside to outside in the peripheral direction; the outer wall of the second connecting pipe is connected with the second spinning connecting piece through a mode of spinning deformation from inside to outside in the peripheral direction; and the push part is connected with the second spinning connecting piece. The equal-inner-diameter connecting pipe joint component adopts the design of equal-diameter structure, respectively adopts the spinning formation at the end parts of the two connecting pipes, and performs the sealing connection for the two connecting pieces; the end surfaces of the first connecting pipe and the second connecting pipe are synchronously sealed through the design of annular sealing rings; and the connecting pipe joint component is suitable for the butt joint of thin-wall pipes.
Description
technical field [0001] The invention is a connection pipe joint assembly, especially a connection pipe joint assembly with equal inner diameters, which is widely used in the field of gas and liquid delivery pipelines in the fields of aerospace, transportation, petrochemical industry, electric power system and the like. Background technique [0002] Known patent applications, such as CN103201551A disclosed "Push Connection Pipe Joint with Sleeve", its specific design scheme includes: comprising a main body member, which is suitable for receiving the main body member at the end of the pipe; the pipe, the pipe includes an energy shaft a pipe clamping device inserted into the first end of the body member and attached to the outer surface of the pipe; and a retainer that holds the pipe in place when the pipe is fully inserted into the body member bit. Additional embodiments include providing joints with a seal against the exterior surface of the pipe, optional load retaining sle...
