Description
Technical field
The utility model relates to a kind of double valve control system for the batch (-type) gas burning kiln, belongs to the heat treatment field.
Background technology
At present, the burner control system that is applied to the batch (-type) gas burning kiln has modes such as digital ratio equation valve control system, the high low temperature handover control system of two proportioning valve and two butterfly valve synchronous operation control systems, these control systems can be controlled the burning capacity of burner, and then the temperature in the control kiln.But these several control system temperature-controlled precisions are not high usually, when current technology does not satisfy customer requirements maybe needs changes product firing process, and burner combustion capacity adjustment narrow range, the complex operation complexity, difficulty is bigger, has increased defect rate, has seriously restricted production efficiency.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of double valve control system for the batch (-type) gas burning kiln is provided, and the temperature-controlled precision height, adjustable range is wide, and is simple to operation, improved production efficiency.
Double valve control system for the batch (-type) gas burning kiln described in the utility model, comprise burner, the burner tail end is communicated with the combustion gas main pipe rail by first electrically operated valve, the burner middle part is communicated with the combustion air main pipe rail by second electrically operated valve, the combustion air main pipe rail is communicated with combustion fan, wind pressure sensor is installed in the combustion air main pipe rail, wind pressure sensor is connected combustion air pressure controller table with combustion fan, combustion air pressure controller table connects industrial computer, and first electrically operated valve links to each other with industrial computer by combustion air pressure controller table with second electrically operated valve.
First electrically operated valve is 60 seconds electrically operated valve of 0-90 ゜ free travel, and stroke is accurate, improves temperature-controlled precision.
Second electrically operated valve is 60 seconds electrically operated valve of 0-90 ゜ free travel, and stroke is accurate, improves temperature-controlled precision.
Operation principle and process:
Industrial computer is controlled second electrically operated valve stroke size and then is controlled the combustion air size that enters burner by combustion air pressure controller table, control first electrically operated valve stroke size and then control the combustion gas size that enters burner by temperature control instrument, two control instruments cooperate to control the burning capacity of burner, and then the temperature in the control kiln.Combustion fan and wind pressure sensor and combustion air pressure controller table form closed-loop control, guarantee the combustion air pressure stability.When the firing process curve changes, only need to revise the temperature and combustion air pressure curve data and the storage that are stored in the industrial computer, industrial computer is set different combustion air pressure in the different temperatures stage, satisfies the requirement that fully burning and furnace atmosphere change.
The beneficial effect that the utility model compared with prior art has is:
Double valve control system for the batch (-type) gas burning kiln described in the utility model, the temperature-controlled precision height, adjustable range is wide, and is simple to operation, improved production efficiency.
