By setting a controller and an electronic precision proportional flow valve, the device achieves precise control of the input and ratio of gas and oxygen flow, thereby realizing precise control of flame size and temperature. Flame size and temperature control no longer rely on manual experience judgment, which greatly improves the accuracy of glass product processing and increases the product qualification rate.

Detailed Implementation

[0014] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] See Figure 1 This utility model provides a technical solution: Example: like Figure 1 As shown, a device for precisely controlling the size of the flame during glass firing includes a first gas path 1, a second gas path 2, a flame holder 3, and a controller 4. The controller 4 is a PLC controller with a touch screen. The outlet of the first gas path 1 and the outlet of the second gas path 2 are connected to the inlet of the flame holder 3 through a three-way connector. The inlet of the first gas path 1 is connected to a gas source, which is natural gas. The inlet of the second gas path 2 is connected to an oxygen source. The first gas path 1 is equipped with a gas flow regulator, which includes a first pressure-stabilizing solenoid valve 5 and a first electronic precision proportional flow valve 6 connected in sequence. The signal input terminals of the first pressure-stabilizing solenoid valve 5 and the first electronic precision proportional flow valve 6 are connected to the first signal output terminal and the third signal output terminal of the controller 4. The second gas path 2 is equipped with an oxygen flow regulator, which includes a second pressure-stabilizing solenoid valve 7 and a second electronic precision proportional flow valve 8 connected in sequence. The signal input terminal of the second pressure-stabilizing solenoid valve 7 and the signal input terminal of the second electronic precision proportional flow valve 8 are respectively connected to the second signal output terminal and the fourth signal output terminal of the controller 4. The controller 4 is used to regulate the gas flow rate of the first gas path 1 through the gas flow regulator and to regulate the oxygen flow rate of the second gas path 2 through the oxygen flow regulator.

[0016] In operation, the flame and temperature magnitude are input via the touchscreen of the PLC controller 4. The PLC controller 4 then controls the opening and closing of the first pressure-regulating solenoid valve 5, the first electronic precision proportional flow valve 6, the second pressure-regulating solenoid valve 7, and the second electronic precision proportional flow valve 8 (where the precision proportional flow valve model is O2SP248067F, and the pressure-regulating solenoid valve model is TD-08) according to pre-set parameters corresponding to the input flame and temperature magnitude. For example, if the required flame and temperature magnitude corresponds to a 1:1 ratio of natural gas to oxygen flow rate, then the opening and closing of the first electronic precision proportional flow valve 6 and the second electronic precision proportional flow valve 8 will be consistent, and the opening and closing degree will correspond to the required flow rate. Similarly, if the required flame and temperature magnitude corresponds to a 2:1 ratio of natural gas to oxygen flow rate, then the opening and closing degree of the first electronic precision proportional flow valve 6 and the second electronic precision proportional flow valve 8 will be maintained at a 2:1 ratio, and the opening and closing degree will correspond to the required flow rate.

[0017] This invention achieves precise control of the input and proportion of gas and oxygen flow by setting up a controller and an electronic precision proportional flow valve, thereby realizing precise control of flame size and temperature. Flame size and temperature control no longer rely on manual experience judgment, which greatly improves the accuracy of glass product processing and increases the product qualification rate.
