Description
Так как площадь поперечного сечени втулки 3 в несколько раз больше площади поперечного сечени внутреннего цилиндра 4, то втулка 3 начнет двигатьс вперед и постепенно откроет впускное отверстие 11 корпуса 1. Это при:ведет к медленному снижению избыточного давлени в газопроводе. Оставшеес небольшое избыточное давление газа будет поддерживать клапан в открытом состо нии.Since the cross-sectional area of the sleeve 3 is several times larger than the cross-sectional area of the inner cylinder 4, the sleeve 3 will begin to move forward and gradually open the inlet 11 of the housing 1. This under: leads to a slow decrease in overpressure in the gas pipeline. The remaining slight gas overpressure will keep the valve open.
Если ударна газова волна будет слишком велика, то втулка 3, мгновенно открыв впускное отверстие И, тут же перекроет выпускное отверстие 12, почти полностью погасив газовую валку. При этом газ не будет подаватьс в ротаметр после срабатывани электромагнитного клапана, а это послужит сигналом ненормальной работы редуктора.If the shock gas wave is too large, then the sleeve 3, instantly opening the inlet And, immediately shut off the outlet 12, almost completely extinguishing the gas roll. At the same time, the gas will not be supplied to the rotameter after the solenoid valve is activated, and this will signal an abnormal operation of the gearbox.
Такой случай может иметь место при неотрегулированном редукторе, допускающем слишком большое натекание газа.Such a case may occur with an unregulated gearbox that allows too much gas leakage.
После того, как электромагнитный клапан перекроет газопровод, давление газа упадет, иAfter the solenoid valve closes the gas line, the gas pressure will drop, and
пружина 6 возвратит вт)лку 3 и цилиндр 4 в исходное положение. Такой предохранительный клапан устанавливают между электромагнитным клапаном и ротометром. spring 6 will return w) lku 3 and cylinder 4 to its original position. Such a safety valve is installed between the solenoid valve and the rotometer.
