Beschreibung
Zusammenfassung:	The invention relates to a valve control circuit of a flue gas purification system. The valve control circuit is characterized by comprising a temperature controller T and a relay KA1, wherein the temperature controller T and the relay KA1 are connected with a power source; a first contact of the temperature controller T is connected with a coil of a time relay SJ2, and a second contact of the temperature controller T is connected with a coil of a time relay SJ1 and a coil of a relay KA2; a normally-open contact of the time relay SJ1 and a normally-open contact of the time relay SJ2 are connected in parallel, and the two ends of the normally-open contact of the time relay SJ1 and the two ends of the normally-open contact of the time relay SJ2 are connected with a contact of a relay KM1 and a contact of the relay KA1; a normally-open contact of the relay KA2 is connected with the normally-open contact of the time relay SJ1 and the normally-open contact of the time relay SJ2 in parallel; and the two ends of the normally-open contact of the relay KA2 are connected with the contact of the relay KA1 and a relay Y. The two ends of a coil of the relay KA1 are connected with the direct-current source. According to the valve control circuit of the flue gas purification system, work of a water pump and a valve body can be reasonably controlled, and waste heat of the flue gas purification system is fully recycled.
