Abstract
A heat and dirt resistant gas fast shut-off valve (flap rotating two way valve) is a special valve designed and developed for hot and dirty gas used in high temperature air combustion system. The valve is composed of a valve body, a valve clack, a driving device and a water cooling system. A sealing base is arranged on the valve body, the valve clack is flexibly connected with a shift lever, a gas cylinder make the shift lever rotate and swing in two directions via the driving shaft, thus the valve clack sealing surface is driven to closely attach and seal the valve sealing base to realize cutting of gas circulation.
Description
The utility model relates to a kind of novel combustion technology, i.e. heat accumulating type high temperature air combustion technology (HTAC).Relate in particular to the heat-resisting coal gas repid cut-off valve that bears dirty of the crucial reversing arrangement of a kind of heat accumulating type high temperature air combustion technology.
HTAC is to settle combustor nozzle in oven in pairs, adopt heat-storage type fume residual heat recovering device, alternately switch air and the flue gas heat retainer (honeycomb ceramic heat accumulator or ceramic bead) that makes it to flow through, can reclaim the sensible heat of high-temperature flue gas to the full extent; Feed combustion gas (fuel oil) and air in the stove and penetrate at a high speed from the burner of particular design and entrainment on every side that flue gas forms the burning of oxygen deprivation state, NOx is generated greatly reduce, since regenerative combustion technology fuel saving significantly, CO
2Discharge amount reduces significantly, has combustion flame simultaneously and elongates advantages such as uniform distribution of temperature field.The heat-resisting coal gas fast shut-off control valve unit that bears dirty is the special valve device that uses the hot dirty gas development and design at the high-temperature air burning system.Can be widely used on industry industrial furnaces such as iron and steel, machinery, coloured, petrochemical industry, building materials, boiler and waste incineration or the heating plant.
The heat-resisting coal gas repid cut-off valve that bears dirty (rotary vane type Twoway valves) technology and device (number of patent application) are the special valves that uses the hot dirty gas development and design at the high-temperature air burning system.Have advantages such as running is reliable, easy for installation, the easy maintenance noise is low.Adopt air cylinder driven, operate steadily, safe and reliable.Be applicable to that temperature is lower than below 500 ℃, the unlatching and the cut-out of the following hot dirty gas of pressure 10kPa.
The heat-resisting coal gas repid cut-off valve that bears dirty (rotary vane type Twoway valves) mainly is made up of valve body (1), flap (3), drive unit cylinder (2) and live axle (5) and constituent (8) etc.
Valve body (1) is by the rectangle cubic chamber and be 90 ° of crossing circular channels and import and export and forms, and this valve body (1) adopts welded structure, and sealing seat (6) is housed on the valve body (1), and flap (3) is made of stainless steel with sealing seat (6), the employing hard sealing structure; Flap (3) flexibly connects with driving lever (4) employing, and cylinder (2) makes driving lever (4) do the bi-directional rotary swing by live axle (5), drives flap (3) motion, and flap (3) goes up sealing surface and valve body (1) sealing seat (6) fits tightly the realization sealing.Driving lever (4) front end adopts the spherical structure to cooperate with flap (3), and the middle part is installed on position limit pin (7), allows positioning tolerance to prevent that flap (3) motion from surpassing.Flap (3) motion is free state, no friction pair, and running resistance is little, can effectively overcome the influence of dust and foul in the gas.
Cylinder (2) is provided with magnetic switch, can show the situation of two positions of valve, uses during for automatic control.
Cylinder (2) adopts single electromagnet electromagnetic valve, and flap (3) is not in the dead center position when having electricity, i.e. coal gas interface closed position; During energising, flap (3) moves to another dead center position, i.e. coal gas interface enable possition, and as cutting off the power supply, valve is in all the time closes the gas inlet position when ventilation.
This valve is provided with constituent (8), is made up of two-way.One the tunnel cools off live axle (5), and cool off bearing on another road, imports and exports in parallelly respectively, imports and exports each interface.Constituent (8) is reduced to below 150 ℃ the bearing working temperature, guarantees bearing and valve safe operation.
Claims (5)
