Description
The utility model belongs to valve.Provide a kind of being installed between industrial furnace and the automatic combustor (fuel oil or combustion gas), be used to prevent that automatic combustor from crossing the electromagnetism flap type of cause thermal damage.
Some industrial furnaces, as the METAL HEATING PROCESS stove, non-ferrous metal smelting furnace, crucible furnace, incinerator, ceramic post sintering stove or the like for realizing the production automation, improve production technology level and energy utilization rate, have adopted automatic combustor (fuel oil or combustion gas).In use have following problem: owing to be lined with refractory material in the burner hearth, the inboard wall of burner hearth temperature raises after automatic combustor starts burning gradually, when temperature in the stove reaches the desired temperature of production technology, and the automatic combustor burn-out; Perhaps produce when finishing normal blowing out or unexpected accident (as outage), though automatic combustor burn-out, and inboard wall of burner hearth temperature still very high (may up to 600-1600 ℃), can do not fall for the moment yet, therefore exist from the radiative heat transfer and the heat transfer by convection of high-temperature burner hearth to automatic combustor, often cause the electric elements in the automatic combustor (to comprise the high-tension electricity ignition transformer, photosensitive element, motor, electric wire etc.) cross cause thermal damage, Residual oil in the nozzle causes nozzle to stop up or atomization badness the automatic combustor cisco unity malfunction in the coking of nozzle mouth.
At present, prevent that the means of above-mentioned fault and measure from quite falling behind or imperfection.The user who has changes the control mode of automatic combustor, when stopping automatic combustor, stops oil (gas) and blow off wind not, and nationality is constantly blown a cold wind in stove and prevented that the automatic combustor components and parts from crossing cause thermal damage.Obviously, this method of operation has been accelerated decrease of temperature speed in the stove, and unfavorable to the production technology that has insulation to require, the waste of the energy is also big.And when running into sudden power, blower fan stall, the protection of also can't drying.The user who has is when automatic combustor stops burning, with manually a baffle plate being inserted between automatic combustor and the burner hearth, or with automatic combustor and burner hearth being broken away from and removing or the like, not only influenced the industrial furnace automatic control process, having increased labor intensity of operating personnel, obviously is not convenient and reliable method yet.
The structure that need improve equipment is arranged, as between automatic combustor and industrial furnace, setting up a flap type that has only protective function.Yet the valve of prior art is all not quite suitable.Solenoid valve as prior art, the driving element of actuator is an electromagnet, the suction that is produced armature by electromagnetic field drives the valve plate motion, though it is simple in structure, flexible movements, but square being inversely proportional to because of the suction size that acts on armature and air clearance, be that the air clearance becomes greatly, suction sharply weakens, so the solenoid valve of prior art is difficult to long stroke, as " motor engineering handbook " (China Machine Press, nineteen eighty-two version) the 8th volume chapter 2 (47-43 page or leaf) described " solenoid valve is generally used for valve aperture on the middle-size and small-size manufacturing mechanism that carries out two controls below 100 millimeters ".And the automatic combustor that industrial furnace adopts usually, the diameter of its burning head is often greater than 100 millimeters, so can not adopt common solenoid valve.Electric valve beyond the solenoid valve, its actuator forms complex structure by servomotor, retarder, position sender unit and servoamplifier, make the valve plate switch by the electric actuator driving, when meeting sudden power, valve plate is difficult to automatically reset, and price also than the expensive 2-3 of solenoid valve doubly.In addition, pneumatic and hydraulic operated valve not only needs additional compressed air source or hydraulic power, and will have electric or electric surging to make transducer, and structure and system are more complicated, and price is also expensive more, and during the chance sudden power, its valve plate also is difficult to automatically reset.In sum, the solenoid valve of prior art product, electric valve, the pneumatic or valve that surges are (referring to " the valve products sample " that Ministry of Machine-Building Industry compiles, China Machine Press's version in 1985; " the valve products catalogue " that China Association of General Machineries ﹠ Valve Industry compiles; mechanical industry is published version in 1993); all be not suitable in the industrial furnace of adapted automatic combustor, time protection automatic combustor is not subjected to the heat transfer of burner hearth hyperthermia radiation and heat transfer by convection and the parts of crossing cause thermal damage as stopping burning very much.
The purpose of this utility model provides a kind of solenoid valve-electromagnetism pendulum-type flap type (hereinafter abbreviating flap type sometimes as) of new structure; it is installed between industrial furnace and the automatic combustor; the startup of its opening and closing and automatic combustor and stopping synchronously; make automatic combustor obtain reliable protection, avoid the mistake cause thermal damage of industrial furnace burner hearth hyperthermia radiation and heat transfer by convection.
The electromagnetism pendulum-type flap type of the utility model design is the Normally closed type valve, and main member comprises valve body, valve plate, valve rod and electromagnet, and the two sides of valve body when closing corresponding to valve plate is respectively valve import and valve outlet port.Be characterized in that plate shaped valve plate and valve rod joins shape such as pendulum together, balance staff is on valve rod, the swing solenoid actuated of valve plate, electromagnet connects together with an end of its motion armature and pulling force connecting rod, the other end of pulling force connecting rod is connected with the pulling force contact of valve rod on valve rod, and pulling force contact and balance staff have certain distance.
The working principle of electromagnetism pendulum-type flap type is such, valve plate moves around the position of the swing generation of balance staff and realizes that valve plate opens and closes the conversion of position, valve plate drives with the pulling force that electromagnet produces around the swing of balance staff, the pulling force of electromagnet puts on the pulling force contact of valve rod by its armature with pulling force connecting rod that armature links together, because pulling force contact and balance staff have certain distance, pulling force from electromagnet on the pulling force contact produces a moment to balance staff, and this moment makes the rotation of valve plate generation around balance staff.Utilize lever principle, the movement travel of valve plate can be the several times of electromagnet armature stroke, has realized that therefore the electromagnet (its armature travel is no more than 100 millimeters) of use general solenoid valve drives the purpose (much larger than 100 millimeters) of big stroke valve plate.Because the driving force of valve plate is an electromagnet, the switch motion of valve is flexible, and can and stop synchronously with the startup of automatic combustor.This electromagnetism pendulum-type flap type is the Normally closed type valve, and when the automatic combustor energising started, the energising of electromagnetism pendulum-type flap type was opened; When the automatic combustor outage stopped burning, electromagnetism pendulum-type flap type also outage simultaneously also cut out automatically, cuts off reliably from thermal radiation and the heat transfer by convection of burner hearth high temperature to automatic combustor.
When automatic combustor uses on industrial furnace, be horizontally disposed with vertical (from up to down) two kinds of positions are set.For this reason, the utility model has designed rectilinear and electromagnetism pendulum-type flap types two kinds of patterns of horizontal.Because of the height factor affecting such as (are the boundary with 1300 ℃) of valve plate diameter (is the boundary with 160 millimeters) and fire box temperature, the partial structurtes of several flap types are slightly variant again.
