Wherein, the normal pressure is less than A, less than B, less than C and less than the safe pressure of the hearth.
In the state that the atmosphere sintering equipment is powered off, the air inlet regulating valve 110 is in a closed state, and the first air outlet regulating valve 211 and the second air outlet regulating valve 212 are in an open state, and the default state can avoid the danger that the equipment is in overpressure due to the fact that internal materials release gas in a high-temperature state when power is suddenly cut off or air is cut off in the high-temperature sintering process; after the atmosphere sintering equipment is powered on, the chamber of the atmosphere sintering furnace 100 is under the normal pressure condition or the pressure is lower than the pressure A condition, at this time, the air inlet regulating valve 110 is in an open state, and the first air outlet regulating valve 211 and the second air outlet regulating valve 212 are both in a closed state.

When dust, condensate and the like cause unsmooth exhaust of the first gas outlet regulating valve 211 of the gas outlet pipe 21 or a large amount of gas is released by heat treatment of a sintering material to cause pressure rise in the hearth of the atmosphere sintering furnace 100, when the pressure detection device 200 detects that the internal pressure of the atmosphere sintering furnace 100 is greater than or equal to B, the gas inlet regulating valve 110 at the gas inlet end is kept open, the opening degree of the first gas outlet regulating valve 211 at the gas outlet end is slowly increased, the opening degree is set according to the volume of the gas inlet pipe 11, the gas outlet pipe 21 and the hearth to slowly increase the exhaust amount, so that the pressure in the atmosphere sintering furnace 100 is slowly reduced, and when the pressure in the hearth is reduced to the value A, the opening degree of the first gas outlet regulating valve 211 at the gas outlet end is restored to the opening degree when the pressure value is A, so as to maintain the pressure in the furnace.
When the pressure detection device 200 detects that the internal pressure of the atmosphere sintering furnace 100 rises to C, the air inlet regulating valve 110 at the air inlet end is turned from open to closed, the first air outlet regulating valve 211 and the second air outlet regulating valve 212 at the air outlet end are completely opened, the audible and visual alarm 400 of the atmosphere sintering equipment starts to sound, the heating switch of the atmosphere sintering furnace 100 is automatically switched off, and the pressure in the hearth is reduced along with the complete opening of the first air outlet regulating valve 211 and the second air outlet regulating valve 212 of the air outlet pipe 21, the closing of the air inlet regulating valve 110 and the switching off of the heating switch.
When the pressure in the hearth is reduced to be lower than the value B, the air inlet regulating valve 110 is changed from closed to open, the first air outlet regulating valve 211 at the air outlet end is in an opening degree under the pressure value B, and the second air outlet regulating valve 212 at the air outlet end is closed; when the pressure of the hearth is reduced to be lower than the value A, the air inlet regulating valve 110 is kept in an open state, the first air outlet regulating valve 211 at the air outlet end is in an opening degree under the pressure value A, the second air outlet regulating valve 212 at the air outlet end is closed, the audible and visual alarm 400 continuously rings, manual operation is needed, the hazard source is reset after being eliminated, and the ring stops.
Further, the opening degree adjustment of the inlet regulating valve 110 at the inlet end and the two outlet regulating valves 210 at the outlet end can be performed in a PID manner.
Specifically, when the pressure in the atmosphere sintering furnace 100 is a (less than the highest positive pressure endured by the atmosphere sintering furnace 100), the inlet regulating valve 110 of the inlet pipe 11 is kept fully open, and the first outlet regulating valve 211 of the outlet pipe 21 is opened to the opening degree α, so that the pressure in the atmosphere sintering furnace 100 is kept a during the sintering process of the atmosphere sintering equipment.
When the pressure in the atmosphere sintering furnace 100 is B, the inlet regulating valve 110 is kept in an open state, the opening degree of the first outlet regulating valve 211 of the outlet pipe 21 is β (α < β), at this time, the amount of exhaust gas increases, the pressure in the atmosphere sintering furnace 100 starts to decrease, and when the pressure in the furnace decreases to be less than B, the opening degree of the first outlet regulating valve 211 of the outlet pipe 21 is restored to α to maintain a specific sintering pressure in the furnace.
When the pressure in the atmosphere sintering furnace 100 is continuously increased to C, the air inlet regulating valve 110 is closed, the first air outlet regulating valve 211 and the second air outlet regulating valve 212 of the air outlet pipe 21 are both completely opened so as to rapidly reduce the pressure in the furnace, the audible and visual alarm 400 rings, and the heating power supply of the atmosphere sintering furnace 100 is automatically cut off so as to ensure the safety of the sintering process.
