Fig. 2 is a schematic partial cross-sectional view of the metal pipe joint assembly of fig. 1.
Detailed Description
The present subject matter of the subject metal fitting assemblies is described more fully below with reference to FIGS. 1-2.
Referring to fig. 1-2, a metal pipe joint assembly comprises a first metal pipe 1, a first joint 2 axially held on the first metal pipe 1, a second metal pipe 3, and a second joint 4 axially held on the second metal pipe 3, wherein the first joint 2 and the second joint 4 are connected through threads, and the first metal pipe 1 is abutted against and in sealing connection with the end face of the second metal pipe 3. Referring to fig. 2, one of the end surfaces of the first metal tube 1 and the second metal tube 3 is a protruding tapered end surface 11, and the other is a recessed tapered end surface 31 which fits with the protruding tapered end surface. In other embodiments, the end surfaces of the first metal tube 1 and the second metal tube 3 are planar. After the two are abutted, the sealing of the end face can be realized. In order to achieve a better sealing effect between the end surfaces of the first metal tube 1 and the second metal tube 3, a sealing ring (not shown) may be provided between the end surfaces of the first metal tube 1 and the second metal tube 3, and an O-ring or a gasket-shaped sealing ring may be selected as the sealing ring. When a seal ring of a specific shape is selected, for example, an O-ring, at least one of the first metal pipe 1 and the second metal pipe 3 is provided with a receiving groove (not shown) for receiving the seal ring in order to receive the seal ring.
Any metal tube is provided with tube parts 12 and 32 with smaller diameters and expansion parts 13 and 33 with larger diameters, and the tube parts 12 and 32 and the expansion parts 13 and 33 are connected through radially extending step parts 14 and 34; each of the joints 2 and 4 is provided with a housing portion 21 and 41 having a smaller diameter and a holding portion 22 and 42 having a larger diameter, and the housing portions 21 and 41 and the holding portions 22 and 42 are connected by radially extending transition portions 23 and 43; the receiving portions 21 and 41 receive the pipe portions, the holding portions 22 and 42 receive the expanding portions 13 and 33, and the transition portions 23 and 43 are axially caught by the stepped portions 14 and 34. The steps 14, 34 extend obliquely in the axial direction with the transition portions 23, 43. The threads are provided on the retaining portions 22, 42 of the fitting.
The first joint 2 and the second joint 4 are provided with polygonal operation parts, and in a preferred embodiment, the metal pipes 1 and 3 and the joints are limited only in the axial direction, and the metal pipes 1 and 3 can rotate relative to the joints 2 and 4 in the circumferential direction. The polygonal operating parts of the joints 2, 4 facilitate the operator to rotate the first and second joints 2, 4 using a tool, and the metal pipes 1, 3 are tightly connected by screw-fitting the first and second joints 2, 4.
The metal pipe connecting structure is very convenient and fast to operate, is convenient for the mutual connection of the metal pipes, is very fast especially when the pipeline of the metal pipes is maintained, and shortens the maintenance time.
In an alternative embodiment, at least one metal tube is fixedly connected to its corresponding joint in the axial and circumferential directions, for example, the metal tube is connected to the joint by welding. The metal tube may be rotated simultaneously with the joint or remain stationary while the joint is connected.
The above technical solution is only illustrative of the present embodiment of the present creation, and not limiting the present creation, and all equivalent changes made by those skilled in the art according to the creation of the present creation belong to the protection scope of the present creation.
