[0020] Please refer to the attached Figure 1 - attached Figure 4 , a heat preservation type HVAC pipe for HVAC engineering of the present utility model includes a first HVAC pipe 1 and a second HVAC pipe 2. A first protective sleeve 3 is arranged on the outer surface of the first HVAC pipe 1, and a second protective sleeve 4 is arranged on the outer surface of the second HVAC pipe 2. The first protective sleeve 3 is tightly clamped with the first HVAC pipe 1. The hollow design of the first protective sleeve 3 is used to protect the outer surface of the entire first HVAC pipe 1, so that during the long-term use in the later stage, the damage is reduced and the overall service life is prolonged. The first protective sleeve 3 is respectively arranged as a protective ring 31, a protective block 32 and a heat preservation layer 33 from the outer ring to the inner ring. The inner wall of the protective ring 31 is arrayedly provided with protective blocks 32. The protective blocks 32 can prevent damage to the internal heat preservation layer 33 and the first HVAC pipe 1 when the protective ring 31 is squeezed. The inner wall of the protective block 32 is fixedly connected to the outer wall of the heat preservation layer 33. The heat preservation layer 33 is sleeved on the outer ring of the first HVAC pipe 1. An installation groove is opened on the top surface of the protective block 32. A connecting piece 5 is arranged between the first HVAC pipe 1 and the second HVAC pipe 2.

[0021] In Embodiment 1, the protective block 32 arranged on the inner wall of the protective ring 31 is tightly clamped with the installation groove, and the protective ring 31 is arranged as a non-closed loop. A split block 311 is arranged at the non-closed loop. The split block 311 is equal in size and the same in shape as the protective block 32. The split block 311 can also be tightly connected with the installation groove. The bottom ends of the split block 311 and the protective block 32 are inclined. The split block 311 can be installed with the heat preservation layer 33 through the installation groove. The split block 311 can make the protective ring 31 and the heat preservation layer 33 be installed. And the split block 311 can make the protective ring 31 be in a disconnected state when disassembled / installed, and rubber blocks are installed at the bottom ends.

By means of the first mounting ring 6 and the second mounting ring 7, in cooperation with the connector 5, the pipe splicing is made more compact, so as to avoid water leakage during the long-term use in the later stage.

[0023] Working principle:

[0024] First, before the first HVAC pipe 1 and the second HVAC pipe 2 leave the factory, they are installed between the first protective sleeve 3 and the second protective sleeve 4. The first HVAC pipe 1 is directly inserted into the inner cavity of the thermal insulation layer 33, and then the protective ring 31 is installed in the installation groove opened on the outer surface of the thermal insulation layer 33 by means of the protective block 32 and the split block 311. During the later maintenance of the first protective sleeve 3, only the protective ring 31 provided on the outside of the first protective sleeve 3 needs to be removed. The first HVAC pipe 1 and the second HVAC pipe 2 are tightly clamped with the connector 5 by means of the first mounting ring 6 and the second mounting ring 7. Thus, the entire work process is completed.
