Description
Technical field
The present invention relates to universal machine valve technology field, relate in particular to a kind of self-cleaning type double-flashboard wear-resistant ceramic valve.
Background technique
Double-flashboard wear-resistant ceramic valve is a kind of Novel control valve door in recent years occurring, due to the application of stupalith, valve is mainly applicable to the use of the keying of coal-burning power plant's dry ash System Grey, slag discharging, also be applicable to mine, papermaking, the use of the keying of the media such as petrochemical industry etc. have wearing and tearing, the dust of corrosion on pipeline.
Shown in Fig. 1 (a), Fig. 1 (b), be respectively plan view and the plan view of more general double-flashboard wear-resistant ceramic valve, as can be seen from the figure, promote piston 3 and move when powered compressor air enters cylinder 1 from process power air inlet 101, piston rod 4 promotes double-gate valve plate 5 throttle downs, and in figure, upper and lower two valve ports 20 are truncated; Promote piston 3 when powered compressor air enters cylinder 1 from backhaul power air inlet 102, piston rod 4 pulls trim double-gate valve plate 5 to open valve, and in figure, upper and lower two valve ports 20 can be communicated with.
Although double-flashboard wear-resistant ceramic valve has been applied industrial ceramics in valve port, at high temperature, deep-etching, after the industry spot of high wearing and tearing is used, greatly improve valve working life, receive significant economic benefit, but carrying after dry ash medium a period of time, also have a very serious problem, the reciprocating stroke end that is exactly the double-gate valve plate in valve body produces fouling phenomenon, and along with the prolongation of service time, the quantity of dust stratification is more and more, dust stratification is through extruding repeatedly, and the density of dust stratification is also more and more, and the dry ash of accumulation is just more and more harder.The existence of two dust stratification hinders the normal keying of valve, affects the normal production of power plant's dust removing system.
The schematic diagram that when Fig. 2 (a), Fig. 2 (b) are depicted as valve closing, valve inner dry ash is piled up, the schematic diagram that when Fig. 2 (c), Fig. 2 (d) are depicted as valve open, valve inner dry ash is piled up.As can be seen from Figure 2, dry ash is in course of conveying, due to technique and medium a variety of causes, dry ash through valve all may have a small amount of residual ash, but be also not enough to affect the normal keying of valve, when valve operation a period of time, due to repeatedly back and forth opening and closing of double-gate valve plate 5, form the dry ash remaining on a small quantity in valve body 2 is pushed repeatedly, the top that opens and closes stroke at double-gate valve plate 5 forms accumulation as shown in A, B; If can not in time the residual dry ash of this accumulation be removed, the dry ash volume of accumulation will increase gradually, finally hinders normally putting in place of double-gate valve plate 5 closed positions and open position, inevitably affects the production run of power plant's dry ash processing system.The dust stratification sweep-out method running at present in the double-flashboard wear-resistant ceramic valve of power plant's dry ash processing system has all adopted shutdown; then take the end cap of a section apart; the artificial pressurized air that uses blows down the dust stratification in valve body, and then by original state, the end cap of taking apart is reinstalled.Whole process is taken a lot of work, time-consuming, and very inconvenient.Power plant runs on dry ash processing system in the urgent need to the double-flashboard wear-resistant ceramic valve that can have pair dust stratification to carry out self-cleaning device and function.
