[0002] PE tee pipe is a plastic pipe fitting, mainly used to change the direction of the fluid. It is made of polyethylene material and has good physical properties. Its mechanical degree is comparable to that of steel pipe. It is one of the series of products commonly used in anti-corrosion pipeline projects.

[0003] After searching, in the prior art, a utility model with announcement number CN216009959U discloses a high-strength composite PE three-way pipe fitting, including a three-way pipe body, a first port is arranged on the left side of the three-way pipe body, a second port is arranged on the right side of the three-way pipe body, a third port is arranged on the top of the three-way pipe body, water pipes are movably installed on the left side of the first port, the right side of the second port and the top of the third port, and reinforcement mechanisms fixedly connected to the first port, the second port and the third port are movably installed on the outside of the three water pipes. The high-strength composite PE three-way pipe fitting, by setting an arc-shaped clamping plate, first rotates the screw at one end of the three-way pipe body, and then sleeves the first port, the second port and the third port on the three-way pipe body on the outside of the three water pipes, so that one end of the water pipe is in contact with the sealing gasket inside the port, and after the water pipe is sleeved, the screw is rotated to make the inner walls of the two arc-shaped clamping plates in contact with the outer wall of the water pipe, thereby achieving the purpose of a stable interface.

When the pipes to be connected are not in the same horizontal plane or vertical plane, the gap needs to be compensated by connecting the pipes, and the convenience of use is poor. Therefore, we propose a composite PE three-way pipe fitting to solve the above problems. Utility Model Content

[0021] 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.

[0022] The utility model provides a technical solution for a composite PE three-way pipe fitting:

[0023] Example:

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, it includes a tee pipe body 1, a connector 2 is provided at the end of the tee pipe body 1, the outer ring of the connector 2 is threadedly connected to a connecting sleeve 3, the inner cavity of the connecting sleeve 3 is provided with a ball head connector 6, the outer wall of the ball head connector 6 is connected to a connecting pipe 7, and one end of the connecting pipe 7 is connected to a flange 8.

[0025] A groove 4 is formed at the top of the connector 2 and the bottom of the connector sleeve 3 , and a ball connector 6 is movably disposed between the two grooves 4 .

[0026] In this embodiment, when in use, the ball head connector 6 is docked in the groove 4 provided in the connector 2, and then the connecting sleeve 3 is connected to the outer ring of the connector 2 by threads. At this time, the connecting sleeve 3 can limit the ball head connector 6, and then the device can be connected to the end of the pipeline through the flange 8. At this time, the fluid entering the three-way pipe body 1 can be discharged into the groove 4 through the connector 2, and enter the ball head connector 6 through the groove 4, and then can be discharged through the connecting pipe 7 to realize the fluid transportation work; the ball head connector 6 can provide a circumferential inclination within a certain range to the connecting pipe 7, and the range is that when the connecting pipe 7 is perpendicular to the connector 2, the connecting pipe 7 is made to move in a circle with the ball head connector 6 as the center until the outer wall of the connecting pipe 7 contacts with any position of the connecting sleeve 3. Within the range of this inclination, there is no need to install an additional adapter on the pipeline to be connected, thereby reducing the difficulty of pipeline connection work to a certain extent, while saving installation costs, and the overall structure is relatively simple and practical.

[0027] Among them, Figure 2 and Figure 3 As shown, a sealing sleeve 9 is provided on the inner wall of the connecting sleeve 3 .

[0028] The outer ring of the connector 2 is provided with a sealing ring 11 .

[0029] In this embodiment, after the connector 2 and the connector sleeve 3 are connected by threads, the sealing sleeve 9 is located between the connector sleeve 3 and the ball connector 6, and the sealing ring 11 is located between the tee body 1 and the connector sleeve 3, thereby sealing the connection to prevent fluid leakage, thereby improving the sealing of the device to a certain extent, and the sealing sleeve 9 can increase the damping of the ball connector 6 during rotation, thereby avoiding unnecessary rotation of the ball connector 6, further improving the overall practicality.

[0030] Among them, Figure 3 As shown, limit rings 10 are provided at both ends of the sealing sleeve 9.

[0031] In this embodiment, the limiting ring 10 is used to limit the sealing sleeve 9 to ensure that the sealing sleeve 9 is always located at the end of the connecting sleeve 3, thereby preventing the ball head connector 6 from causing displacement of the sealing sleeve 9 during rotation, thereby ensuring the sealing ability of the sealing sleeve 9 is reliable, thereby further improving the overall practicality.

[0032] Among them, Figure 1 and Figure 4 As shown, the outer ring of the tee pipe body 1 is provided with a protective shell 12.

[0033] In this embodiment, the three-way pipe body 1 is wrapped in a protective shell 12. When the device collides with an external object, the protective shell 12 can protect the three-way pipe body 1 to prevent external force from directly acting on the three-way pipe body 1, thereby preventing the three-way pipe body 1 from being damaged by external force to a certain extent, thereby improving the overall safety of use and increasing the service life.
