Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole realities
Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of fan coil of low noise, including straight tube 1,
The left and right ends of straight tube 1 are respectively connected with elbow union joint 2, and the junction of straight tube 1 and elbow union joint 2 is provided with connecting plate 8,
Two groups of connecting plates 8 are bolted, and the other end of elbow union joint 2 is connected with ring flange 3, and the side wall of ring flange 3 uniformly connects
Stiffener plate 4 is connected to, and the other end of stiffener plate 4 is connected with the outer wall of elbow union joint 2, the side wall of ring flange 3 is connected with
Sealing gasket 5, straight tube 1 and elbow union joint 2 are bimetallic tube, are uniformly pacified between straight tube 1, the inner tube of elbow union joint 2 and outer tube
Equipped with sound panel 6, the top and bottom of the inner chamber of straight tube 1 is mounted on decelerating barrier group 7, and top and bottom decelerating barrier group 7
It is staggered, the inner chamber of elbow union joint 2 is provided with axis pin base 9, and axis pin base 9 is connected with spoiler 10, spoiler by bearing pin
