[0044] Example 1

[0045] like Figures 1-14 As shown, this embodiment provides a cold and heat source distribution pipeline system, including a straight pipe 1, a direct connector 2, a planar elbow 3, a three-dimensional elbow 4, a tee 5, and a ground air supply box 6. Two adjacent straight pipes 1 are connected by direct connector 2. Direct connector 2 is turned by planar elbow 3 and / or three-dimensional elbow 4.

A flow guide plate 31 is provided inside the planar elbow 3. The flow guide direction of the flow guide plate 31 can be from one interface to another, and is not a straight-line guide. The insulation material 11 is polyurethane.

[0046] The regulating valve 8 includes a valve body 81, an adjusting knob 82, an extension port 83, and an adjusting plate 84. Extension ports 83 are provided on both sides of the valve body 81, and the adjusting plate 84 is installed inside the extension ports 83.

However, when using a three-dimensional elbow 4 for the change of direction, since the three-dimensional elbow 4 has an extension pipe opening, two three-dimensional elbows 4 can be directly assembled to form a 90° bend. Planar elbows 3 are typically used in... For switching between wall and floor installations, the 3D elbow 4 is typically used when changing from floor to wall paving or vice versa. The tee connector 5 can separate a single passage into two, reducing noise. The tee connector 5 is usually assembled with the straight pipe 1 following the flat elbow 3. The entire cold and heat source distribution pipeline system leads to the ground air supply box 6, which is connected to the connection port 61 of the ground air supply box 6 via the straight pipe 1.
