 Jianlou monitoring instrument WDK3 one of the two pressure monitor together, for testing the tightness of the two in order to open the electromagnetic valve. DK2F program run by the synchronous gear motor through a cam micro switch control. 
 The inlet side of the valve through the emptying of the test segment gas and pressure monitoring and testing, the burner side of the valve by the injected gas and the pressure drop monitoring to detect segment detection. If the pressure rise to the first detection stage does not allow the height, and from this high degree of over-reduced in the second stage of detection, DK2F will latch in the fault location and stop the burner continues to run. 
 Jianlou monitoring instrument WDK3 applies automatic leak detection device using gas between the two solenoid valves, the detection system either as a sealed testing device used independently, but also with all automatic combustion devices using the. Circuit connection location of the regulator and the Monitor section, so make the burner only to check the tightness after work. 
 For heating and industrial use of gas equipment, gas generators, etc., did not pass the exhaust pipe to the outside world.
