Abstract
Устройство автоматического управления предохранительным клапаном котла, содержащее контакты включения сети, магнитопровод с катушкой, якорем и штоком, корпус клапана с входным и выходным патрубками, отличающееся тем, что параллельно источнику питания и друг другу через выключатель подсоединены три реле времени, имеющие различные временные уставки, катушка электромагнита, при этом последовательно с первым реле соединен нормально закрытый контакт второго (электромагнитного) реле, а параллельно первому реле подключен световой сигнализатор, а в цепи между вторым и третьим (электромагнитными) реле последовательно соединены между собой и к источнику питания нормально открытый контакт третьего (электромагнитного) реле и нормально закрытый контакт первого реле, при этом параллельно второму (электромагнитному) реле подключен световой сигнализатор, а параллельно второму (электромагнитному) реле через концевой выключатель, концевик которого жестко связан с крышкой клапана, соединен контактор, а параллельно третьему (электромагнитному) реле электрически соединены через контакт контактора звуковой и световой сигнализаторы. A device for automatically controlling the boiler safety valve, which contains the network connection contacts, a magnetic circuit with a coil, an armature and a rod, a valve body with inlet and outlet pipes, characterized in that three time relays are connected in parallel with the power source and to each other through a switch, having different time settings, an electromagnet coil; in this case, a normally closed contact of the second (electromagnetic) relay is connected in series with the first relay, and a light signal is connected in parallel with the first relay a torus, and in the circuit between the second and third (electromagnetic) relays, the normally open contact of the third (electromagnetic) relay and the normally closed contact of the first relay are connected in series with each other and to the power source, while a light signal device is connected in parallel with the second (electromagnetic) relay, and in parallel a second (electromagnetic) relay is connected through a limit switch, the end of which is rigidly connected to the valve cover, and a parallel contactor is connected to the third (electromagnetic) relay electrically through a contactor act audible and visual alarm.
