[0025] The external protective sleeve of the existing insulating three -way pipe is composed of two half three -way structures, and needs the help of screw and other tools when installing and dismounting, and the operation process is relatively cumbersome. Meanwhile, when there is a gap between the two protective sleeves, the foaming material filled between the three -way pipe and the protective sleeve is easy to leak, thereby affecting the overall heat preservation effect, in order to solve the above technical problems, the technical scheme is as follows:

[0026] Refer toFigs. 1-5 As shown, a heat preservation pipe fitting with PE soft shell protection, which comprises a tee pipe fitting 1, three connecting ports of the tee pipe fitting 1 are respectively provided with connecting pipes 2, the outer sides of the tee pipe fitting 1 and the connecting pipes 2 are respectively sleeved with protective sleeve pipes 3, heat preservation layer pipes 4 are respectively arranged between the tee pipe fitting 1, the connecting pipes 2 and the protective sleeve pipes 3, the tee pipe fitting 1 comprises a first branch pipe 11, a second branch pipe 12 and a third branch pipe 13, the first branch pipe 11, the second branch pipe 12 and the third branch pipe 13 form a T-shaped structure and are in communication with each other, the protective sleeve pipes 3 comprise a first sleeve pipe 31, a second sleeve pipe 32, a third sleeve pipe 33 and a fourth sleeve pipe 34, the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33 are respectively sleeved on the first branch pipe 11, the second branch pipe 12 and the third branch pipe 13, and the fourth sleeve pipe 34 is sleeved on the outer side of the connecting pipe 2, one end of the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33 is inserted into the port where the first branch pipe 11, the second branch pipe 12 and the third branch pipe 13 are connected with the connecting pipe 2, and the other end of the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33 abut against each other;

[0027] The heat preservation layer pipes 4 are installed on the inner sides of the first sleeve pipe 31, the second sleeve pipe 32, the third sleeve pipe 33 and the fourth sleeve pipe 34 in an interference fit mode. Meanwhile, the heat preservation layer pipes 4 are connected with the first branch pipe 11, the second branch pipe 12, the third branch pipe 13 and the connecting pipe 2 in an interference fit mode. The close combination and stable connection between the heat preservation layer pipes 4 and the tee pipe fitting 1, the connecting pipe 2 and the protective sleeve pipes 3 are effectively ensured, so that the stability and sealing property of the overall structure are improved, and good heat preservation effect is ensured;

[0028] Therefore, in the use process, first, the heat preservation layer pipes 4 are sleeved into the inner sides of the first sleeve pipe 31, the second sleeve pipe 32, the third sleeve pipe 33 and the fourth sleeve pipe 34. Then, the first sleeve pipe 31, the second sleeve pipe 32, the third sleeve pipe 33 and the fourth sleeve pipe 34 with the heat preservation layer pipes 4 are sleeved into the outer sides of the first branch pipe 11, the second branch pipe 12, the third branch pipe 13 and the connecting pipe 2. One side of the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33 abut against each other to form a T-shaped structure, and the other side of the fourth sleeve pipe 34 is also closely attached to the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33. Thus, the heat preservation and protection of the tee pipe fitting 1 and the connecting pipe 2 are ensured, and the three detachable sleeve pipes are installed on the tee pipe fitting 1, so that the installation and dismounting process becomes simple and fast.

[0029] In the installation process, the connecting pipe 2 is directly connected with the three interfaces of the tee pipe fitting 1 by inserting. In order to improve the stability and sealing performance of the connection between the connecting pipe 2 and the tee pipe fitting 1, the first branch pipe 11, the second branch pipe 12 and the third branch pipe 13 are respectively provided with a convex ring groove 14 at the end connected with the connecting pipe 2, and a sealing ring 5 is arranged in the convex ring groove 14. The inner side of the sealing ring 5 is in interference fit with the outer side of the connecting pipe 2, so as to form a tight connection. In this way, when the connecting pipe 2 is inserted into the first branch pipe 11, the second branch pipe 12 and the third branch pipe 13, not only the stability of the connection is ensured to prevent the connecting pipe 2 from loosening during use, but also the sealing performance of the connection part is effectively guaranteed to avoid fluid leakage between the connecting pipe 2 and the tee pipe fitting 1, and reliable operation under high pressure or high flow conditions is ensured.

[0030] The first branch pipe 11, the second branch pipe 12 and the third branch pipe 13 are also respectively provided with a limiting part 6 for limiting during cooperation with the connecting pipe 2. The limiting part 6 is located inside the convex ring groove 14, and the diameter of the limiting part 6 gradually decreases from outside to inside. Therefore, during installation, the connecting pipe 2 is inserted into the first branch pipe 11, the second branch pipe 12 and the third branch pipe 13 respectively. When the inner side of the connecting pipe 2 contacts the limiting part 6, it indicates that the installation position has been reached. This avoids the problems of loose connection or fluid leakage caused by incomplete insertion of the connecting pipe 2, and ensures the stability and sealing performance of the connection between the tee pipe fitting 1 and the connecting pipe 2.

[0031] In order to ensure the stability of the connection of the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33, the abutting surfaces of the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33 are respectively nested with mutually attracted magnetic blocks 7. After installation is completed and the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33 abut each other, the magnetic blocks 7 arranged in the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33 will be automatically attracted and firmly combined, thereby ensuring the stability of their connection, ensuring the stability of the connection of the first sleeve pipe 31, the second sleeve pipe 32 and the third sleeve pipe 33, and when the protective sleeve pipe 3 needs to be removed for maintenance, it can be directly pulled out. The installation and disassembly operation is simple, avoids complicated disassembly operation, and improves the installation and maintenance efficiency.

[0032] The heat preservation layer pipe 4 is a sponge pipe, which has excellent heat insulation performance and good elasticity, can effectively reduce the conduction of heat, and thus improves the heat preservation effect of the system. The soft texture of the sponge pipe enables the sponge pipe to closely adhere to the surface of the tee pipe fitting 1 and the connecting pipe 2, and form a uniform heat preservation layer, which not only effectively prevents heat loss, but also prevents the temperature of the pipe from being affected by the external environment. In addition, the sponge pipe is light in weight, easy to install, has good anti-aging performance and durability, and can maintain stable heat preservation effect in long-term use, further improving the thermal efficiency and overall stability of the tee pipe fitting 1 and the connecting pipe 2. Compared with the existing foamed heat preservation layer, the sponge pipe can avoid leakage and has more uniform distribution.

[0033] The tee pipe fitting 1 and the connecting pipe 2 are both stainless steel hollow pipe fittings, and the stainless steel material has excellent corrosion resistance, oxidation resistance and good mechanical properties, which ensures that the pipe fitting can operate stably for a long time in various harsh environments.

[0034] The protective sleeve 3 is made of PE pipe, which has excellent corrosion resistance and chemical resistance, can effectively resist the corrosion of various acids, bases and chemicals, is suitable for use in various harsh environments, thus effectively protecting the normal operation of the tee pipe fitting 1 and the heat preservation layer pipe 4, and the good toughness and softness of the PE pipe enable the PE pipe to easily adapt to different installation requirements, have strong impact resistance, and can maintain stable physical properties even in low temperature environment, and are not easy to break or deform.

[0035] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
