Description
Technical field
This utility model belongs to gas burning system technical field, is specifically related to a kind of gas control system for Tea Processing.
Background technology
Along with popularizing of China's natural gas, this green, economical, convenient, the energy of high heating value has been that a lot of highly energy-consuming field is first-selected, it is mainly used in fresh leaves de-enzyming in processing field of tea leaves, drying etc. needs high temperature, the operation of highly energy-consuming, these operations are required for thermostatic control, large and small fire is the most all used to control temperature, i.e. reach to close big fire during the temperature needed, only burn little fire, when after temperature declines less than the temperature set, light again big fire, thus realize thermostatic control, although this gas control system can realize temperature automatic control, but temperature fluctuates up and down very big (error ＞ ± 15 DEG C), easily occur completing the phenomenons such as impermeable or Gao Huo, it is unfavorable for the processing of high-quality Folium Camelliae sinensis.
Utility model content
The problem existed for prior art, the purpose of this utility model is that design provides the technical scheme of a kind of gas control system for Tea Processing.
Described a kind of gas control system for Tea Processing, including gas header pipe and one group of combustion gas arm being connected with gas header pipe, it is characterized in that being sequentially provided with electric controlled regulating valve, electromagnetic valve and one group on described combustion gas arm goes out Gas Pipe, the described Gas Pipe that goes out is provided with branch's ball valve and burner, ignition electrode and thermocouple is coordinated on described burner, described ignition electrode junction point firearm, described electric controlled regulating valve, lighter and thermocouple signal connects controller, and described ignition electrode signal connects electromagnetic valve.
Described a kind of gas control system for Tea Processing, it is characterised in that described gas header pipe is provided with total ball valve.
Above-mentioned a kind of gas control system for Tea Processing, controller is used to control gas quantity, when actual temperature with arrange temperature the biggest time, controller can instruct electric controlled regulating valve gas quantity and can automatically hold to maximum, to be rapidly heated, when actual temperature moves closer to the temperature set, controller can instruct electric controlled regulating valve and constantly reduce the supply of combustion gas, until it reaches completely close gas supply during the temperature of setting；Otherwise, when actual temperature is less than the temperature arranged, controller can instruct electric controlled regulating valve and combustion gas is gradually opened and lighted to electromagnetic valve, thus realizes accurate thermostatic control.This utility model controls very accurate, can reach error≤± 3 DEG C.

Detailed description of the invention
This utility model is further illustrated below in conjunction with Figure of description.
As it can be seen, a kind of gas control system for Tea Processing includes gas header pipe 2 and the one group of combustion gas arm 4 being connected with gas header pipe 2, combustion gas arm 4 can be expanded as required.Gas header pipe 2 is provided with total ball valve 3, to control total combustion gas.It is sequentially provided with electric controlled regulating valve 5, electromagnetic valve 6 and one group on combustion gas arm 4 and goes out Gas Pipe 8.Go out Gas Pipe 8 and be provided with branch's ball valve 7 and burner 9.Ignition electrode 10 and thermocouple 11, ignition electrode 10 junction point firearm 12 is coordinated on burner 9.Ignition electrode 10 is used for lighting a fire, and thermocouple 11 monitors temperature in real time.Electric controlled regulating valve 5, lighter 12 and thermocouple 11 signal connect controller 1, and ignition electrode 10 signal connects electromagnetic valve 6.
The Automatic Control Theory of this utility model is as follows.
One, operating procedure: open controller 1, manually design temperature numerical value on controller 1, by automatic control mode.
Two, temperature controlled processes:
1, artificial design temperature is that pass to the temperature of controller 1 with thermocouple 11 consistent, does not the most order to electric controlled regulating valve 5；
2, thermocouple 11 passes to the temperature of controller 1 higher than artificial design temperature, then controller 1 order electric controlled regulating valve 5 closes a numerical value (amount of program setting, depending on size is by temperature difference)；
3. thermocouple 11 passes to the temperature of controller 1 less than artificial design temperature, then controller 1 order electric controlled regulating valve 5 leaves a numerical value (amount of program setting, depending on size is by temperature difference).
Three, sparking and security control:
1, controller 1 controls electromagnetic valve 6 and opens, and electric controlled regulating valve 5 opens 40%, and lighter 12 starts sparking simultaneously, and as 5 seconds also fail on fire, 12 signals of lighter pass to controller 1, and electromagnetic valve 6 cuts out by controller 1；
2, controller 1 controls electromagnetic valve 6 and opens, and electric controlled regulating valve 5 opens 40%, and lighter 12 starts sparking simultaneously, plays in 5 seconds, and controller 1 notifies electric controlled regulating valve 5, and follow procedure sets to be opened；
3, in production process, unburned if any indivedual burners 9,12 signals of lighter pass to controller 1, and electromagnetic valve 6 cuts out by controller 1, igniting of resetting automatically after several seconds.
