Abstract
The utility model provides a gas-flow rotary regulator, which is in particular suitable for all-level regulation of the gas amount which is distributed at the flame path of a coke oven. The utility model comprises a rotor, a stator and a tubular axle, one end face of the rotor and the stator is respectively provided with a special hole, the rotor can rotate freely relatively to the stator. When the hole of the rotor overlaps fully or partially with the hole of the stator, gas can pass, and when the two holes don't overlap at all, the gas feeding can be cut off; the size of the air flow can be displayed by the scale of the rotor.
Description
The utility model provides a kind of gas flow rotary actuator, and particularly a kind of can being applicable to regulated the device that is distributed in coke oven flue coal gas amount.
Conventional art adds at coke oven union is installed on the hot leg pipe, is placed with a removable orifice plate in the union, regulates the coal gas amount that is distributed in each flue, is by the dismounting union, changes that the orifice plate of different-diameter realizes.Realize adjustings at different levels, need to prepare the different orifice plate in a large amount of apertures, because coke oven base roof plate sinks, reasons such as the relative dislocation during installation, very difficult when changing orifice plate, the time that not only needs is long, labor intensity is big, also will stop to arrange full the firing chamber heating sometimes, directly influences the adjusting of horizontally-arranged temperature.
The purpose of this utility model discloses a kind of coke oven exactly and adds hot leg pipe coal gas amount rotary actuator, change the operation of dismounting union on the conventional art, orifice plate on this device is once fixing, therefore can save a large amount of standby orifice plate and union, can realize being distributed in the adjustings at different levels of flue coal gas amount, and can cut off infeeding of coal gas and have the blind plate effect concurrently.
This rotary actuator that is achieved in that of the present utility model is made up of rotor, stator and tubular axis.Rotor and stator are the garden tubular, and an end face has a fan shaped borehole, and two is fan-shaped not only concentric, and radius, angle also all equate.Rotor is enclosed within on the tubular axis, and stator is enclosed within on the rotor, and rotor can rotate arbitrarily with respect to stator.When fan-shaped complete overlapping on epitrochanterian fan shaped borehole and the stator or when overlapping, just there is coal gas to pass through, when not overlapping fully no coal gas passes through the size of Throughput, can show by the scale on the retaining handle 6, can realize being distributed in the adjustings at different levels of flue coal gas amount like this.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the sectional drawing of rotary actuator, and Fig. 2 is its right elevation.1 is tubular axis among the figure, and 2 is rotor, and 3 is stator, and rotor 2 is enclosed within on the tubular axis, has fan shaped borehole 4 on the end face of rotor 2.Have a fan shaped borehole 5 on one end face of stator 3, stator 3 is enclosed within on the rotor 2.Turning handle 7 is respectively one with rotor and retaining handle 6 with tubular axis 1, and tubular axis 1 is connected with the horizontally-arranged pipe, and stator 3 links to each other with incorgruous four-way by a hexagon nut.Like this, rotor 2 rotation arbitrarily between tubular axis 1 and stator 3.Because fan shaped borehole 4 is concentric with fan shaped borehole 5, radius equates, so when the two had lap, the angle of overlaid part and equitant area just had a relation one to one.And gas speed one regularly is directly proportional with the area of this lap by the coal gas amount of fan shaped borehole 4 with fan-shaped 5 overlaids part in arm.Therefore, the angle of two fan shaped borehole overlaids parts and the gas flow by this lap also have relation one to one.The coal gas amount that is distributed in flue so just can be by representing the fan shaped borehole 4 and the graduation line of the angle of fan shaped borehole 5 overlaids part to show on the retaining handle 6.
When two fan-shaped complete when overlapping, draw two line segments by the center of circle along two strings, line segment length equals to keep off the radius (center of circle of retaining handle 6 and turning handle 7 is on same center line, and radius equates) of handle 6, and groove just is engraved in the folded scope of the projection of two line segments on turning handle (can with reference to Fig. 2).The position of " 0 " graduation line on the turning handle is corresponding with left side line segment position of projection on turning handle, and the maximum scale line is corresponding with the right." 0 " graduation line on the retaining handle and maximum scale line after tubular axis and the welding of horizontally-arranged pipe, rotate the turning handle rotor and just rotate arbitrarily with respect to tubular axis in contrast.When " 0 " of turning handle graduation line and " 0 " of retaining on the handle when graduation line is corresponding, two is not fan-shaped overlapping fully, and Throughput is zero, otherwise there is gas to pass through, when " 0 " graduation line on the turning handle was corresponding with the maximum scale line on the retaining handle, two is fan-shaped overlapping fully, the Throughput maximum.Like this, just can observe out tolerance size by two overlapping holes.
Between rotor 2 and the tubular axis 1, the gap between rotor 2 and the stator 3 is very little, and can smear molybdenum disulfide betwixt, and can prevent that so not only raw coke oven gas from entering its gap, but also can play lubrication, therefore, the phenomenon that rotor can not occur being stuck.
This controller structure is simple, easily processing, and easy to operate, a people finishes Primary regulation and only needs 1-2 second, has not only greatly alleviated workman's labour intensity, and regulates accurately. When heatingup of coke oven battery, body of heater overhaul and working condition change, use this adjuster to control well as required ascending, descending speed, improve the horizontally-arranged temperature.
The utility model can also be applicable to the adjusting of other gas flow under the low pressure.
