Description
Technical Field
The utility model relates to the technical field of ventilation compensators, in particular to a large-caliber polytetrafluoroethylene ventilation compensator.
Background
Pipeline system is collected to steel plant acid mist, the pipeline that produces vibrations when the fan operation will lead to being connected with the fan damages, produces the pipeline compensation problem in order to solve the fan vibrations, so need install the compensator at the fan mouth, fan export nominal size generally all is more than DN800, the unable machine-shaping of preparation compensator tetrafluoro pipe.
Disclosure of Invention
In order to solve the technical defects in the prior art, the utility model provides a large-caliber polytetrafluoroethylene ventilation compensator.
The technical solution adopted by the utility model is as follows: heavy-calibre polytetrafluoroethylene ventilation compensator, including the compensator body, the both ends of compensator body all be equipped with erodees protection device, erode protection device including the compensator protective sheath, the compensator protective sheath set up on the passway at compensator body both ends, the both ends of compensator body still be equipped with the compensator flange, compensator flange and compensator protective sheath between still be equipped with corrugated tetrafluoride pipe.
And the compensator flange and the compensator protective sleeve are fixed through bolts.
The end part of the compensator flange is provided with a through hole, a hexagon bolt is arranged in the through hole, and a limiting pipe sleeve is sleeved on the hexagon bolt.
The compensator is characterized in that a negative pressure resistant protection device is further arranged on the compensator body and comprises a negative pressure ring, and the negative pressure ring is arranged in an inner cavity of the compensator body.
And a compensator lug is also arranged on the compensator flange.
The utility model has the beneficial effects that: the utility model provides a large-caliber polytetrafluoroethylene ventilation compensator which comprises a compensator body, wherein two ends of the compensator body are respectively provided with a scouring protection device, each scouring protection device comprises a compensator protection sleeve, the compensator protection sleeves are arranged on passage openings at two ends of the compensator body, compensator flanges are also arranged at two ends of the compensator body, a corrugated tetrafluoride pipe is also arranged between each compensator flange and each compensator protection sleeve, the technical problem that the compensator body is easily abraded when the compensator body flows through acid mist gas due to the fact that some granular media are always contained in the acid mist gas is solved by arranging the scouring protection devices, a negative pressure ring is additionally arranged at a trough of an inner cavity of the compensator, when a fan generates negative pressure, the negative pressure ring can effectively prevent the compensator from being shriveled, and the safety and reliability of an acid mist pipeline collection system of a steel plant are effectively solved.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
FIG. 2 is a schematic view of the structure of the present invention.
The compensator comprises a compensator body 1, a compensator protective sleeve 2, a compensator flange 3, a corrugated tetrafluoride pipe 4, a hexagon bolt 5, a limiting pipe sleeve 6, a negative pressure ring 7 and a compensator ear 8.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Heavy-calibre polytetrafluoroethylene ventilation compensator, including compensator body 1, the both ends of compensator body 1 all be equipped with and erode protection device, erode protection device including compensator protective sheath 2, compensator protective sheath 2 set up on the passway at 1 both ends of compensator body, the both ends of compensator body 1 still be equipped with compensator flange 3, compensator flange 3 and compensator protective sheath 2 between still be equipped with ripple tetrafluoro pipe 4. And the compensator flange 3 and the compensator protective sleeve 2 are fixed through bolts. The technical problem that the compensator main body is easily abraded when the acid mist gas flows through the compensator main body due to the fact that some granular media are always contained in the acid mist gas is solved.
The end part of the compensator flange 3 is provided with a through hole, a hexagon bolt 5 is arranged in the through hole, and a limiting pipe sleeve 6 is sleeved on the hexagon bolt 5.
The compensator is characterized in that a negative pressure resistant protection device is further arranged on the compensator body 1 and comprises a negative pressure ring 7, and the negative pressure ring 7 is arranged in an inner cavity of the compensator body 1. When the fan generates negative pressure, the negative pressure ring can effectively prevent the compensator from absorbing shriveling
And a compensator ear 8 is also arranged on the compensator flange 3.
The skilled person should understand that: although the present invention has been described in terms of the above embodiments, the inventive concepts are not limited to the embodiments, and any modifications that utilize the inventive concepts are intended to be included within the scope of the appended claims.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
