Abstract
The utility model discloses a flue damper which comprises a pipeline body, wherein the pipeline body is provided with an inlet end and an outlet end, and a shutter matched with the inner wall of the pipeline body is arranged in the pipeline body and is connected with the pipeline body through a rotating shaft movably. The flue damper has the advantages of convenience for operation, simple structure and low failure rate.
Description
Technical field
The utility model relates to a kind of flue damper.
Background technology
Existing metal melts the refining industry, and closing of its flue all is to adopt artificial mode to control, and its control difficulty is large, inconvenient operation, and fault rate is high, needs to do further to improve.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and a kind of flue damper is provided, and the utility model is easy to operate, and is simple in structure, failure rate is low.
Its technical scheme is as follows:
A kind of flue damper comprises pipe body, and this pipe body has entrance point and the port of export, is provided with the flashboard that matches with its inwall in pipe body, and this flashboard is flexibly connected by rotating shaft and described pipe body.
The below describes further technical scheme:
Inwall at described pipe body is provided with limited block, and this limited block and described rotating shaft are positioned on the same cross section of described pipe body.
Be provided with balancing weight and pulling eye at described flashboard, balancing weight, pulling eye lay respectively at the both sides of described rotating shaft.
Entrance point, the port of export at described pipe body are equipped with flange.
The below describes advantage or the principle of aforementioned techniques scheme:
1, be provided with flashboard in pipe body, flashboard rotates around the axis and can realize opening or closing of pipe body, and is simple in structure, failure rate is low, simultaneously more convenient operation;
2, the inwall at pipe body is provided with limited block, can limit the turned position of flashboard by this limited block, and is lower in off position, and flashboard is closely engaged with the pipe body inwall;
3, be provided with balancing weight and pulling eye at flashboard, the pulling pulling eye, flashboard overcome balancing weight gravity and the rotation, flashboard can be opened, unclamp pulling eye, flashboard cuts out under the Action of Gravity Field of balancing weight, open with close more convenient;
4, entrance point, the port of export at pipe body is equipped with flange, can dock with other pipeline easily by flange.

The specific embodiment
The below is elaborated to embodiment of the present utility model:
As shown in Figure 1 and Figure 2, a kind of flue damper comprises pipe body 10, and this pipe body 10 has entrance point 11 and the port of export 12, is provided with the flashboard 20 that matches with its inwall in pipe body 10, and this flashboard 20 is flexibly connected by rotating shaft 30 and described pipe body 10.
Wherein, be provided with limited block 13 at the inwall of described pipe body 10, this limited block 13 is positioned on the same cross section of described pipe body 10 with described rotating shaft 30.Be provided with balancing weight 21 and pulling eye 22 at described flashboard 20, balancing weight 21, pulling eye 22 lay respectively at the both sides of described rotating shaft 30.Entrance point 11, the port of export 12 at described pipe body 10 are equipped with flange.
The present embodiment has following advantage:
1, be provided with flashboard 20 in pipe body 10, flashboard 20 around the shaft 30 rotations can be realized opening or closing of pipe body 10, and is simple in structure, failure rate is low, simultaneously more convenient operation;
2, the inwall at pipe body 10 is provided with limited block 13, can limit by the turned position of 13 pairs of flashboards 20 of this limited block, and is lower in off position, and flashboard 20 is closely engaged with pipe body 10 inwalls;
3, be provided with balancing weight 21 and pulling eye 22 at flashboard 20, the pulling pulling eye 22, flashboard 20 overcome balancing weight 21 gravity and the rotation, flashboard 20 can be opened, unclamp pulling eye 22, flashboard 20 cuts out under the Action of Gravity Field of balancing weight 21, open with close more convenient;
4, entrance point 11, the port of export 12 at pipe body 10 is equipped with flange, can dock with other pipeline easily by flange.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
