The invention relates to an automatic pressure control device for gas furnace pressure. The automatic pressure control device comprises a gas furnace and a chimney positioned at one end of the gas furnace, wherein an air header pipe is arranged on the gas furnace; one end of the air header pipe corresponding to the adjacent chimney is provided with communicated air blowpipes; an automatic valve is arranged between the air blowpipe and the air header pipe; and a plurality of air blow holes are formed on the surface of the air blowpipe corresponding to the chimney. In the automatic pressure control device for the gas furnace pressure, the air blowpipe is communicated with the air header pipe, and the air blow holes are formed on the air blowpipe; when the pressure inside the gas furnace is lower than the external pressure, the automatic valve is opened to ensure that the air blowpipe is communicated with the air header pipe, and the air inside the air header pipe is blown out through the air blow holes, so that an air curtain is formed at one end of the gas furnace to prevent external oxygen from entering a hearth of the gas furnace and prevent a workpiece inside the hearth from being oxidized; and when the pressure inside the gas furnace is higher than the external pressure, the automatic valve is closed, the air inside the gas furnace is released through the chimney to ensure constant pressure inside the hearth of the gas furnace.
Description
technical field [0001] The invention relates to a control device, in particular to a gas furnace pressure automatic pressure control device, which belongs to the technical field of gas furnace control. Background technique [0002] At present, the furnace pressure control method using gas furnace is relatively vague. When the combustion pressure in the furnace is high, the furnace pressure is high, and when the combustion pressure in the furnace is low, the furnace pressure is low. When it is lower than the external atmospheric pressure, external oxygen enters the furnace, which will cause the workpiece in the furnace to be oxidized, thereby affecting the quality of the workpiece. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an automatic pressure control device for gas furnace pressure, which has a simple structure and is easy to use, can prevent workpieces in the furnace from being ox...
