Abstract
The utility model provides a flue gas valve which comprises a valve body, a butterfly plate, a valve shaft, stuffing, bearings, an upper bracket and a lower bracket, wherein the butterfly plate is mounted in the valve body and is connected with the valve shaft through a pin; the upper bracket is mounted at the end part of the valve body; the lower bracket is mounted at the tail of the valve body; the stuffing is mounted in the valve body through a gland; a gap is reserved between the butterfly plate and the valve body; and the bearings are mounted on the upper bracket and the lower bracket respectively. The utility model has the benefits as follows: the valve body and the butterfly plate cannot be blocked, the valve shaft and the bearings cannot be locked, the valve is operated flexibly and the service life is long.
Description
Affiliated technical field
The utility model relates to a kind of valving, especially a kind of smoke valve.
Background technique
Use the butterfly valve that adopts S type structure mostly at the metallurgy industry fume pipe at present, under 500-600 ℃ high temperature, because thermal expansion, card is stifled easily between butterfly plate and the valve body, and locking phenomenon also easily takes place between valve shaft and the bearing, influences the usability of valve.
Summary of the invention
For overcoming existing smoke valve because elevated temperature heat expands, card is stifled easily between butterfly plate and the valve seat, and the deficiency of locking also easily takes place between valve shaft and the bearing, and the utility model provides a kind of smoke valve.
The technological scheme that its technical problem of solution of the present utility model adopts is a kind of smoke valve, comprise valve body, butterfly plate, valve shaft, filler, bearing, upper bracket, lower support frame, butterfly plate is installed in the valve body, butterfly plate is connected by bearing pin with valve shaft, upper bracket is installed in the end of valve body, and lower support frame is installed in the afterbody of valve body, and filler is installed in the valve body by gland, leave the gap between butterfly plate and the valve body, bearing is installed in respectively on upper bracket and the lower support frame.
It is stifled that the beneficial effects of the utility model are that valve body and butterfly plate can not block, and valve shaft and bearing can lockings, and valve operation is flexible, long service life.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is embodiment's a sectional structural map;
Among the figure: 1. bearing; 2. upper bracket; 3. gland; 4. filler; 5. valve body; 6. valve shaft; 7. bearing pin; 8. butterfly plate; 9. lower support frame.
Embodiment
As shown in Figure 1, a kind of smoke valve, comprise valve body 5, butterfly plate 8, valve shaft 6, filler 4, bearing 1, upper bracket 2, lower support frame 9, butterfly plate 8 is installed in the valve body 5, butterfly plate 8 is connected by bearing pin 7 with valve shaft 6, upper bracket 2 is installed in the end of valve body 5, lower support frame 9 is installed in the afterbody of valve body 5, filler 4 is installed in the valve body 5 by gland 3, leave the gap between butterfly plate 8 and the valve body 5, can not block stifled phenomenon between valve body and the butterfly plate under 500-600 ℃ the high temperature like this, bearing 1 is installed in respectively on upper bracket 2 and the lower support frame 9, away from thermal source, guarantee that the rotation of valve shaft is flexible.
