Abstract
The utility model provides an expansion joint. The expansion joint avoids the pipe vibration problem caused by the fact that a metal piece produces rigid force transmission at the connecting part easily, and simultaneously compensates and adapts to the expansion in hot and the contraction in cold of a ventilator. The expansion joint is composed of a metal frame and a non-metal skin, and is characterized in that the metal frame is encircled into a drum shape, and the non-metal skin covers the drum-shaped frame.
Description
(1) technical field
The utility model relates to the ventiduct system field, is specially the expansion joint that is used for the wind and smoke pipeline enclosure.
(2) background technique
Traditional expansion joint that is used for the wind and smoke pipeline enclosure is generally metal bellows, because metalwork easily produces rigid power transmission connecting, and pipeline vibration occurs, makes metalwork produce biased problem such as move easily because ventilator expands with heat and contract with cold again.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of expansion joint, and it has avoided metalwork the problem of pipeline vibration to occur in the easy rigid power transmission of generation of connection, can expand with heat and contract with cold to ventilator simultaneously and make compensation and adaptation.
Its technological scheme is such, and it comprises metal frame, nonmetal covering, it is characterized in that: described metal frame surrounds cydariform, and described nonmetal covering covers in described cydariform framework.
In the said structure of the present utility model, owing to the expansion joint skin is nonmetal covering, the metalwork of comparing, pliability is good, the damping of energy sound-absorbing, the problem of minimizing pipeline vibration can be expanded with heat and contract with cold to ventilator simultaneously and be made compensation and adaptation.
(4) description of drawings
Fig. 1 is the plan view in the utility model;
(5) embodiment
See Fig. 1, the utility model comprises metal frame 1,3, nonmetal covering 2, and metal frame 1,3 integral body surround cydariform, and nonmetal covering 2 covers in the cydariform framework.
Claims (1)
1, a kind of expansion joint, it comprises metal frame, nonmetal covering, it is characterized in that: described metal frame surrounds cydariform, and described nonmetal covering covers in described cydariform framework.
