Abstract
The utility model provides a tertiary air gate valve of cement calcining kiln, belongs to cement manufacture equipment field, and including valve body, valve plate, rings draw the chain, still include sealing device, sealing device install in the upper end of valve plate, including the fastener, sealed clamp plate, sealing filler, the fastener pass sealed clamp plate and will seal the clamp plate and compress tightly in the valve plate upper end, sealed clamp plate install in the upper end of valve plate, adopt the fastener to compress tightly, sealing filler install between sealed clamp plate and valve body, adopt sealed clamp plate to compress tightly between valve body and valve plate, have can avoid hot -blast and spray drawing the chain on, reduce the characteristics to the corruption of drawing chain and rings.
Description
Technical field
The utility model belongs to field of cement production equipment, particularly a kind of tertiary air gate valve of cement burning kiln.
Background technique
In cement production process, the tertiary air gate valve of cement burning kiln, the equipment of wind flow in the control kiln being mounted in calcining kiln end, in calcining kiln normal work period, tertiary air gate valve is often in opening state, owing to having gap between the flashboard of gate valve and valve body body, wind in calcining kiln is through gate valve, the temperature of wind is very high, add in windward and have high-temperature dust, high warm air is from the top being leaked to valve plate between the valve plate and valve body of gate valve, it is adopt chain to be hung by the suspension ring on valve plate that the valve plate of conventional tertiary air gate valve is opened, crane gear pulls chain, chain traction valve plate is up, complete the unlatching of tertiary air gate valve, during closedown, crane gear loosens chain, valve plate relies on deadweight to fall, complete the closedown of tertiary air gate valve, because high warm air and high-temperature dust move upward from valve body and valve plate gap, conduction chain and suspension ring are in the long-term erosion environment of high warm air and high-temperature dust, and easily cause the fracture of conduction chain or suspension ring, cause valve plate automatically to fall and close tertiary air gate valve, causing cement burning kiln to quit work, cause heavy losses to manufacture of cement, simultaneously, because tertiary air gate valve is arranged on the end of cement burning kiln, be run in the air at height, safeguard and overhaul all very difficult.
Summary of the invention
For existing cement burning kiln tertiary air gate valve Problems existing, the utility model proposes a kind of tertiary air gate valve of cement burning kiln, comprise valve body, valve plate, suspension ring, conduction chain, it is characterized in that: also comprise seal arrangement; Described seal arrangement is arranged on the upper end of valve plate, comprises fastening piece, sealing clamp, stuffing box packing; Described fastening piece passes sealing clamp and sealing clamp is pressed on valve plate upper end; Described sealing clamp is arranged on the upper end of valve plate, adopts fastening piece to compress; Described stuffing box packing is arranged between sealing clamp and valve body, adopts sealing clamp to be pressed between valve body and valve plate; Described stuffing box packing is heat-resistant material.
Beneficial effect
The beneficial effects of the utility model are, spray hot wind can be avoided on conduction chain, reduce the corrosion to conduction chain and suspension ring.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model
1. valve body, 2. valve plate, 3. suspension ring, 4. conduction chain, 5. fastening piece, 6. sealing clamp, 7. stuffing box packing.
Embodiment
Further illustrate implementation methods of the present utility model by reference to the accompanying drawings now, as Fig. 1, select the steel plate of thickness 12 millimeters, be made into the rectangle frame of circumferential width 80 millimeters, as seal trim strip 6, the Outside Dimensions of rectangle frame is less than valve body 1 cross-sectional dimension 3-5 millimeter, the end face of rectangle frame is produced the through hole of diameter 12 millimeters, hole separation distance 100 millimeters; According to quantity and the position in the hole on sealing clamp 6, become the tapped hole of M10 in valve plate 2 upper-end surface respective production, the degree of depth 50 millimeters; Select asbestos slate as stuffing box packing 7 in this example, also can select aluminosilicate fiberboard; This example selects the asbestos slate of thickness 10 millimeters, makes the strip of width 50 millimeters, also can select different width according to the gap between valve body 1 from valve plate 2; Between upper-end surface stuffing box packing 7 being placed on valve body 1 and valve plate 2, sealing clamp 6 is pressed, selects the outer-hexagonal bolt of NBS as fastening piece 5 in this example, according to the corresponding fastening piece 5 of how many outfits in the hole on sealing clamp 6; Adopt fastening piece 5 that sealing clamp 6 is pressed on valve plate 2 upper-end surface, just complete enforcement of the present utility model; Because sealing material is by the clearance seal between valve body 1 and valve plate 2; hot blast and dust can not upwards corrode conduction chain 4 and suspension ring 3 from gap; decrease the damage of suspension ring 3 and conduction chain 4; ensure the normal operating condition of cement burning kiln tertiary air gate valve; decrease dead time, improve manufacturing efficiency.
Claims (4)
