Snakelike metal tube is connect with a metal fiber burner 10, another the 4th ball valve of outlet end of first pipe three-way connection
1D and snakelike metal tube 5 are connect with another metal fiber burner 10, and gas pipeline 9 is connected to pneumatic proportional valve 2 and precision
Between 8 outlet end of electrically-operated servo valve.
In auxiliary unit, the first ball valve 1A is blast tube main valve, and second to the 4th ball valve 1B, 1C, 1D is blast tube
Bypass valve controls unlatching and closing for the pipeline gas that is connected respectively.Since gas medium has corruption to valve body and its conveyance conduit
Erosion acts on, so paying the utmost attention to ball valve 1A, 1B, 1C, 1D, gas pipeline 9 and snakelike metal when selecting valve and conveyance conduit
Acid resistance, alkali resistance, the resistance to pressure of the material of pipe 5, to ensure the reliability of the burning temperature control system gas medium transport vehicle,
Durability and safety.
Pneumatic proportional valve 2 in device, temperature control thermocouple 6, wind turbine 7, elaborate servo motor-driven valve 8, metal fiber burner
10 constitute formant.Two metal fiber burners 10 are symmetricly set on both sides, temperature control thermocouple 6 and wind turbine at molding burner
7 are arranged between two metal fiber burners 10, and pneumatic proportional valve 2 is arranged in the connecting pipe after 1 A of the first ball valve,
Elaborate servo motor-driven valve 8 is connect by third pipeline T-joint and connecting pipe with two metal fiber burners 10.
In formant, metal fiber burner 10 is the core element of the burning temperature control system.Metal fiber burner
It is the more high-end trendy product of heating of the field of combustion technology researched and developed in recent years.The characteristics of product is that burning is abundant, nothing
Flare cigarette carbon, to by heater element（Such as plate glass billot）Heat erosion it is few, in addition burning area is big（Heat radiation surface is big）And
And combustion front can be according to by heater element（Such as plate glass billot）Configuration design, therefore the more general heater of its thermal radiation effect
It is much better than, and since its surface is covered with one layer very thick of fine metal mesh suede, so constituent parts when metal fiber burner works
The thermal exposure of area error in terms of experimental data is small, i.e., the thermal field generated when metal fiber burner works is uniform.This is special
The homogenizing of interior quality of the point to the forming of plate glass billot and after shaping is particularly important.Therefore metal fiber burner is plate
Important core element in glass billot continuous production processes.
In formant, the effect of temperature control thermocouple 6 is temperature when burning between measuring two metal fiber burners 10
Degree.Its operation principle is that have small electric in temperature control thermocouple 6 when temperature changes between two metal fiber burners 10
Stream passes through, which is stored in Thermal Meter therewith, and is converted into digital display pattern.
In formant, elaborate servo motor-driven valve 8 is another key element in the system.Its operation principle is when two
When temperature changes between a metal fiber burner 10, the electric signal prompt through temperature control thermocouple 6, elaborate servo motor-driven valve
8 when will be drawn according to plate glass billot its be molded the technological parameter of burner setting correct automatically compressed at its valve inlet it is empty
Then the air inflow of gas will be defeated by metal fiber burner 10, in addition fraction by the major part of the compressed air of this valve
The compressed air of same pressure is transferred to pneumatic proportional valve 2 through gas pipeline 9, as pumping signal.
In formant, pneumatic proportional valve 2 is that a gas flow distributes regulating element automatically, and operation principle is when next
When being changed from the air pressure via gas pipeline 9, the diaphragm valve sector-meeting in pneumatic proportional valve 2 changes it under the action of the spring
The size of air-flow valve port, to change the air inflow of natural gas and total gas output in the unit interval, when the gas of gas pipeline 9
When pressing unchanged, the size of the air-flow valve port of pneumatic proportional valve 2 is constant, the air inflow of natural gas and total goes out in the unit interval
Throughput will not change.
Fired from temperature control thermocouple 6 → elaborate servo motor-driven valve 8 → gas pipeline, 9 → pneumatic proportional valve, 2 → metallic fiber
Burner 10 is a closed-loop control.
In formant, the effect of wind turbine 7 is that the thermal field of burner glass forming cavity is made to homogenize.Because in burner forming cavity
Design, making, in installation process there are dead angle, and fiber burner 10 is to always can be by by the coverage effect of heating target
Different degrees of limitation, leading to burner glass forming cavity temperature, there are non-uniform phenomenons.Another aspect temperature control thermocouple 6 measures
Be temperature among two metal fiber burner 10, and temperature of the forming cavity at dead angle in two metal fiber burners 10
Between temperature there is difference in theory, i.e. the feedback of its electric signal has limitation.In view of this consideration, the present invention is additionally arranged wind
7 element of machine, under the action of wind turbine 7, in burner forming cavity thermal cycle aggravate, as time goes by, in forming cavity everywhere in temperature
Degree gradually becomes identical.And then realize the uniform technological requirement of thermal field.The uniformity of thermal field is to weigh a weight of temperature control system
Want index.
Alarm 11 in device is the security context monitoring unit of the burning temperature control system.
Add the design thinking foundation of security context monitoring unit：The gas used due to the burning temperature control system of the present invention
Medium is natural gas, when the concentration of natural gas being detained in the temperature control system ambient enviroment that burns is more than certain value, will there is peace
Full hidden danger adds alarm 11 and sets safe threshold according to manufacturing technique requirent, is effectively protected operation field, avoids accident
Generation.
