Description
манометрического реле 1 между вторым входом камерой высокого давлени 10 и камерой расширени 4. Реле неизменно при мгновенной разгерметизации затвора 5 регистрирует положительный переиад давлений, т. е. всплеск давлени в камере расширени 4. А поскольку при разгерметизации затвора 5 между его горловиной 11 в непосредственной близости от жала валов и камерой высокого давлени 10 машины образуетс отрицательный перепад, то подсоедин ют второй трубопровод 12 дифференциального манометрического реле 1 к камере расширени 4.a pressure switch 1 between the second input of the high-pressure chamber 10 and the expansion chamber 4. The relay invariably, with instantaneous depressurization of the shutter 5, records a positive over-pressure, i.e. a surge in pressure in the expansion chamber 4. And since during the depressurization of the shutter 5 between its neck 11 In the vicinity of the shaft end and the high-pressure chamber 10 of the machine, a negative differential is formed, then the second pipeline 12 of the differential pressure switch 1 is connected to the expansion chamber 4.
Дифференциальное манометрическое реле 1 настроено на определенную величину перепада давлени , соответствующую опасной величине утечки рабочей среды. При достижении этого перепада контакт ДРД замыкаетс .The differential pressure switch 1 is set to a certain value of the differential pressure corresponding to a dangerous amount of leakage of the working medium. When this differential is reached, the DRD contact closes.
загораетс лампа ЛК и звенит звонок. Срабатывает реле PI, которое своим нормально замкнутым контактом размыкает цепь.the LK lamp illuminates and the bell rings. The relay PI, which by its normally closed contact opens the circuit, triggers.
Предмет изобретени Subject invention
Устройство дл герметизации проходного отверсти камеры высокого давлени , содержаш ,ее затвор со щелевой горловиной, соединенной с одним из входов дифференциального манометрического реле, запорный клапан и камеру расширени , расположенную между камерой высокого давлени и горловиной затвора , отличающеес тем, что, с цельюA device for sealing a through-passage of a high-pressure chamber, comprising: a shutter with a slit neck connected to one of the inputs of a differential pressure switch, a shut-off valve and an expansion chamber located between the high-pressure chamber and the shutter-neck,
повышени чувствительности при аварийной разгерметизации затвора, камера расширени соединена со вторым входом дифференциального манометрического реле.increase the sensitivity during emergency depressurization of the shutter; the expansion chamber is connected to the second input of the differential pressure switch.
