Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent;

for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product;

it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.

The embodiment provides a three-way pipe fitting, which comprises a first connector 1, a second connector 2, a third connector 3 and a U-shaped pipe; the first interface 1 and the second interface 2 are respectively positioned at two ports of the U-shaped pipe; the third interface 3 is communicated with the middle part of the U-shaped pipe; the three-way pipe fitting is of an integrally formed structure.

It should be noted that, the three-way pipe fitting provided by the utility model is of an integrated structure, the third interface 3 can be connected with various connecting water outlet external pipe fittings for use, and the two interfaces can be connected with the pipe by hot melting to form a water return pipeline, so that the problems of more pipe fittings, more installation procedures and low efficiency in the traditional installation are avoided; the installation adaptability is stronger, and the method can be more suitable for different installation and construction requirements; in addition, the U-shaped pipe has a smooth arc transition structure, so that the resistance of water can be reduced, and the pressure of hot water in the pipe fitting can be maintained; in addition, the return water pipelines connected with the two interfaces are close to the water outlet connected with the third interface, so that the effect of using hot water immediately after opening can be realized.

Wherein, the first interface 1 is a socket; the second interface 2 is a socket; the third interface 3 is a socket.

Further, the axis of the third port 3, the axis of the first port 1, and the axis of the second port 2 are parallel and located on the same plane.

It should be noted that the purpose of locating the central axes of the three ports in the same plane is to minimize the resistance of the tee to water, and not to increase the resistance because water needs to be rotated through more angles between the ports or between the port and the third port.
