Abstract
The utility model provides a high-temperature metallic compensator which relates to the fields of hot air duct and damped compensators. The high-temperature metallic compensator comprises a nozzle, a corrugated pipe, a draft tube, a pull rod, lug plates, a packing and flanges which are arranged at the two ends of the nozzle. The lug plate is vertically welded on the outer wall of the nozzle. The lug plates are connected through the pull rods. The corrugated pipe is welded on the outer wall of the fracture surface of the nozzle. The draft tube is welded inside the corrugated pipe parallel to the nozzle and the packing is placed between the outer wall of one end of the draft tube and the inner wall of the nozzle. The high-temperature metallic compensator has the advantages of being simple in structure, easy to produce and install high in high temperature resistance ability, not easy to damage and deform under the environment of high temperature and long in service life.
Description
Technical field:
The utility model relates to the compensator field for hot-flow flue compensation, damping, is specifically related to a kind of high-temperature metal compensator.
Background technique:
All need adopt the high-temperature metal compensator in the hot-flow flue of the industries such as environmental protection and energy saving industry, complete hot electricity power enterprise, desulphurization denitration equipment, iron and steel, thermoelectricity, the high-temperature metal FlexbleJoint is by the metal corrugation compensator that consists of its operative body (a kind of elastic element) and hold the annexes such as pipe, support, flange, conduit to form.Utilize effective dilatation of hot blast high-temperature metal FlexbleJoint operative body metal corrugation compensator, to absorb pipeline, conduit, container etc. by the dimensional changes former thereby that produce such as expand with heat and contract with cold, or compensation pipes, conduit, container etc. axially, laterally and angular displacement, also can be used for noise-and-vibration-reduction.
At present on the market high-temperature metal compensator structure is complicated, and volume is large, and heat-resisting ability is relatively poor, if use for a long time yieldingly under hot environment, even damages, and working life is short.
The model utility content:
The purpose of this utility model provides a kind of high-temperature metal compensator, and it is simple in structure, is easy to produce and install, and heat-resisting ability is strong, uses to be difficult for deformed damaged, long service life under hot environment.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises adapter, bellows, guide shell, pull bar, otic placode, packing and flange, the two ends of taking over are provided with flange, the outer wall vertical of taking over is welded with otic placode, and connect by pull bar between the otic placode, fracture outer wall in the middle of taking over is welded with bellows, and bellows interior is parallel to adapter and is welded with guide shell, and is provided with packing between the inwall of an end outer wall of guide shell and adapter.
Be provided with the high temperature resistant heat insulation filler in the cavity between described bellows and the guide shell.
Principle of the present utility model is: owing to being provided with fracture in the middle of taking over, and incision position adopts guide shell to connect, and by packing_seal, forms to have axially, laterally and the structure of angular displacement compensate function.Be provided with the high temperature resistant heat insulation filler in the bellows, greatly prolonged working life.
The utility model is simple in structure, is easy to produce and install, and heat-resisting ability is strong, uses to be difficult for deformed damaged, long service life under hot environment.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, this embodiment is by the following technical solutions: it comprise take over 1, bellows 2, guide shell 3, pull bar 4, otic placode 5, packing 6 and flange 7, the two ends of adapter 1 are provided with flange 7, the outer wall vertical of adapter 1 is welded with otic placode 5, and connect by pull bar 4 between the otic placode 5, the fracture outer wall of taking in the middle of 1 is welded with bellows 2, and bellows 2 inside are parallel to adapter 1 and are welded with guide shell 3, and is provided with packing 6 between the inwall of an end outer wall of guide shell 3 and adapter 1.
Be provided with the high temperature resistant heat insulation filler in the cavity between described bellows 2 and the guide shell 3.
The principle of this embodiment is: owing to be provided with fracture in the middle of taking over 1, and 3 connections of incision position employing guide shell, and by packing 6 sealings, form the structure with axial, horizontal and angular displacement compensate function.Be provided with the high temperature resistant heat insulation filler in the bellows 2, greatly prolonged working life.
This embodiment is simple in structure, is easy to produce and install, and heat-resisting ability is strong, uses to be difficult for deformed damaged, long service life under hot environment.
