[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] like Figure 1-3 As shown, the utility model provides a technical solution: a metal insert pipe joint, including a tee pipe body 1, the tee pipe body 1 is T-shaped, the tee pipe body 1 includes two fusion pipe ports 11 and an internally threaded pipe port 12, the two fusion pipe ports 11 are connected to other pipelines by welding, and the two fusion pipe ports 11 are perpendicular to the internally threaded pipe port 12, a socket 121 is arranged at the end of the internally threaded pipe port 12, the inner diameter of the socket 121 of the internally threaded pipe port 12 is larger than the inner diameter of the threaded section of the internally threaded pipe port 12, the internally threaded pipe port 12 is threadedly connected to one end of a metal external wire pipe head 2 with threads arranged on the outer surface, and the other end of the metal external wire pipe head 2 extends outside the internally threaded pipe port 12, so as to facilitate the disassembly and replacement of the tee pipe body 1 and the metal external wire pipe head 2 and adjust the extended length of the metal external wire pipe head 2.
[0017] The metal outer thread pipe head 2 is also threadedly connected to the inner thread annular gasket 3 and the inner thread cap 4 respectively. The inner thread annular gasket 3 is installed in the inner thread pipe mouth 12, and an inner sealing gasket 5 is sandwiched between the inner thread annular gasket 3 and the socket 121, and the inner sealing gasket 5 is sleeved on the metal outer thread pipe head 2. The inner thread annular gasket 3 is pressed against the socket 121 to limit the length of the metal outer thread pipe head 2 threadedly connected in the inner thread pipe mouth 12. A socket 41 is provided at one end of the inner thread cap 4 to be inserted into the socket 121. The inner thread cap 4 is T-shaped, and an outer sealing gasket 6 sleeved on the socket 41 is sandwiched between the inner thread cap 4 and the inner thread pipe mouth 12.
[0018] A spring component 7 is also sleeved on the metal outer thread pipe head 2, and the spring component 7 is located between the inner thread annular gasket 3 and the inner thread cover cap 4. The spring component 7 will generate a continuous elastic force, so that the threaded connection between the inner thread annular gasket 3 and the inner thread cover cap 4 continues to maintain a friction force, thereby preventing the inner thread annular gasket 3 and the inner thread cover cap 4 from rotating loose, and also ensuring the connection tightness and sealing effect at the position of the inner sealing gasket 5 and the outer sealing gasket 6.
[0019] During installation and use, the position of the inner thread annular gasket 3 is adjusted according to the length of the metal outer thread pipe head 2 required to extend outside the tee pipe body 1, so as to limit the length of the metal outer thread pipe head 2 threadedly connected in the inner threaded pipe mouth 12, and then the metal outer thread pipe head 2 with the inner sealing gasket 5 is threadedly screwed into the inner threaded pipe mouth 12, and the inner sealing gasket 5 is used for sealing at the connection position between the metal outer thread pipe head 2, the inner threaded pipe mouth 12 and the inner thread annular gasket 3, and the outer sealing gasket 6 is mounted on the inner thread cap 4. After tightening the metal outer thread pipe head 2 into the internal threaded pipe mouth 12, the spring part 7 and the inner thread cap 4 can be installed on the metal outer thread pipe head 2 in sequence, and the inner thread cap 4 can be tightened on the metal outer thread pipe head 2 so that the inner end of the inner thread cap 4 is inserted into the socket 121 and the spring part 7 is pressed, and the inner thread cap 4 and the internal threaded pipe mouth 12 are clamped with the outer sealing gasket 6. The outer sealing gasket 6 is used to seal the connection between the inner thread cap 4 and the internal threaded pipe mouth 12.
