Abstract
The utility model relates to a kind of copper blast furnace off-gas dedusting butterfly valve.It comprises support, valve body lower support, stuffing box packing and axle sleeve on valve body, valve rod, butterfly plate, valve body; the valve rod running through valve body, butterfly plate is provided with two protecting jackets; one end of protecting jacket is stretched in valve body support; the other end stretches in butterfly plate central sleeve, in the outer peripheral groove in protecting jacket two end part, be inlaid with seal ring respectively.The utility model has the advantages that and Korrosionsmedium can be stoped to enter running clearance between valve rod and axle sleeve, avoid the generation of corrosion products between valve rod and axle sleeve, eliminate valve rod by the defect of locking, extend the working life of valve.
Description
Technical field
The utility model relates to a kind of butterfly valve, especially a kind of butterfly valve for copper blast furnace off-gas dust collecting process.
Background technique
Current copper blast furnace off-gas dust collecting process uses traditional dust and gas butterfly valve, and because medium is to the corrosion of valve rod or axle sleeve, to cause between valve rod and axle sleeve gap to be in relative rotation full of corrosion products, valve rod is by locking, and butterfly plate can not realize switching motion.
Model utility content
Goal of the invention of the present utility model is just to provide a kind of copper blast furnace off-gas dedusting butterfly valve, which overcomes dedusting butterfly valve valve rod in prior art can not be realized switching motion deficiency by locking, butterfly plate.
For achieving the above object, the utility model adopts as follows
technological scheme:
A kind of copper blast furnace off-gas dedusting butterfly valve; comprise valve body, butterfly plate, valve rod, stuffing box packing, axle sleeve; it is characterized in that: run through valve body, butterfly plate valve rod upper and lower two-part on be respectively equipped with the identical protecting jacket of two structures; one end of upper and lower two protecting jackets is stretched in butterfly plate central sleeve respectively; the other end of upper and lower two protecting jackets stretches into respectively on valve body and supports in interior and valve body lower support; at protecting jacket two end part, outward edge is provided with groove, is inlaid with seal ring one and seal ring two in groove respectively.
The utility model adopts technique scheme to produce
beneficial effectfor:
The utility model copper blast furnace off-gas dedusting butterfly valve is after project organization innovation; the seal ring inlayed in the protecting jacket that valve is set up and protecting jacket two end part outward edge groove stops Korrosionsmedium to enter valve rod and axle sleeve in relative rotation in gap effectively; avoid the generation of corrosion products; reduce valve driving torque, improve the working life of valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model copper blast furnace off-gas dedusting butterfly valve;
Fig. 2 is the partial enlarged drawing of circle part A in Fig. 1.
In figure: 1. valve body supports; 2. axle sleeve; 3. stuffing box packing; 4. valve rod; 5. valve body; 6. butterfly plate; 7. valve body lower support; 8. protecting jacket; 9. seal ring one; 10. seal ring two.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Fig. 1, shown in Fig. 2, a kind of copper blast furnace off-gas dedusting of the utility model embodiment butterfly valve, valve body supports 1 and the upper end portion of butterfly plate 6 central sleeve and the underpart of valve body lower support 7 and butterfly plate 6 central sleeve, the protecting jacket 8 being sleeved on valve rod 4 outer surface is set respectively, one end of protecting jacket 8 is stretched on valve body and is supported in 1 or valve body lower support 7, the sealing between valve rod 4 and valve body 5 is guaranteed by the seal ring 1 be embedded on protecting jacket 8, the other end of protecting jacket 8 stretches into butterfly plate 6 central sleeve upper end portion or underpart, the sealing between valve rod 4 and butterfly plate 6 central sleeve is guaranteed by the seal ring 2 10 be embedded on protecting jacket 8.In valve operation process; by protecting jacket 8 and the seal ring 1 be embedded in the outward edge groove of protecting jacket 8 two end part and seal ring 2 10; effective prevention Korrosionsmedium enters the running clearance between valve rod 4 and axle sleeve 2; avoid valve rod 4 by locking or clamping; reduce the driving torque of valve, extend the working life of valve.
