Description
Technical field
The utility model belongs to the gas stop valve technical field, particularly relates to a kind of stop valve that heat-accumulating industrial furnace combustion gas and flue gas switch usefulness fast that is used for.
Background technique
Heat-accumulating industrial furnace is at metallurgy industry extensive use, and one of critical component that influences the heat-accumulating industrial furnace performance is exactly the stop valve that combustion gas and flue gas switch usefulness fast, it to the requirement of structural type is: a three way valve should have a left side, right, following three chambeies, cavity of resorption is chewed flange with the burning of industrial furnace and is connected, chamber, a left side is connected with gas pipeline as fuel chamber, right chamber is connected with fume pipe as smoke chamber, gas valve is being controlled the connecting passage of cavity of resorption and fuel chamber, smoke valve is being controlled the connecting passage of cavity of resorption and smoke chamber, and gas valve and smoke valve are all by finishing the switch motion of valve to connected cylinder.The stop valve requirement in use that combustion gas and flue gas are switched fast is: when heat accumulating type on the industrial furnace burns when chewing burning, the gas valve in the fuel chamber of left chamber is opened, and the while smoke valve of right chamber smoke chamber is closed.Combustion gas enters in the industrial furnace, in the industrial furnace accumulation of heat of heat accumulating type burn the heat retainer chewed with the room temperature gas-preheating to 800 that obtained after 1000 degrees centigrade in stove and preheating air combustion, can increase substantially the combustion temperature of the high-risk combustion gas of lower calorific value, to reach the temperature process requirement of industrial furnace heating.When the heat accumulating type burning is chewed accumulation of heat on the industrial furnace, gas valve in the chamber fuel chamber of a left side is closed, the smoke valve of right chamber smoke chamber is opened simultaneously, take a certain amount of flue gas away, the accumulation of heat of the interior heat accumulating type of industrial furnace this moment is burnt the heat retainer of chewing and is received 1000 to 1300 degrees centigrade furnace high-temperature gas gradually, make heat retainer preheating, accumulation of heat, thermal energy storage is in heat retainer.So being used for stop valve that heat-accumulating industrial furnace combustion gas and flue gas switch usefulness fast one of in use crucial is that whether the gas valve of fuel chamber closes tightly in the three way valve, it is related to quick-fried toot the problem of tempering; Two be whether to have poisonous gas leakage problem between the sliding position of the valve rod that is connected with cylinder and three way valve.
If being applied in combustion gas, the flue gas pipeline system, the empty cigarette stop valve of the pneumatic commutation of existing threeway has problems, 1) the Sealing material of each valve and body cavity passage does not meet heat resistant and wear resistant and decreases requirement, long-term work is worn and torn easily, is worn out, cause by gas seal not sternly, gas leakage in the valve takes place, and to produce the possibility of tempering detonation big; 2) the valve stem slides position that is connected with cylinder only compresses with asbestos packing.Because the repeatedly to-and-fro motion of valve rod and the sealing compensation ability of packing produce the gap between valve rod and packing.Easily cause toxic gas to leak, near maintenance man personal safety is caused potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of stop valve that heat-accumulating industrial furnace combustion gas and flue gas switch usefulness fast that is used for of high temperature resistant, wear-resistant, good sealing effect.
The purpose of this utility model realizes by following technical proposals:
