Description
Устройство содержит цилиндрический корпус 1, предназначенныйThe device comprises a cylindrical housing 1, designed
для встраивания в трубопровод, размещенный внутри корпуса 1 и закрепленный на нем глухой цилиндрический каркас 2, на котором установлена тороидальная оболочка 3, деформируемая под действием давления с возможностью перекрытия кольцевого промежутка между каркасом 2 и корпусом 1. Оболочку 3 предпочтительно выполнять резинокордной.for embedding in a pipeline placed inside the housing 1 and mounted on it a blind cylindrical frame 2 on which a toroidal shell 3 is mounted, deformable under pressure with the possibility of overlapping the annular gap between the frame 2 and the housing 1. The shell 3 is preferably rubber-cord.
Корпус 1 выполнен с каналом 4 в стенке, соединенным с полостью оболочки 3, для подачи в нее среды под давлением и сброса давления. Корпус имеет фланцы 5.The housing 1 is made with a channel 4 in the wall connected to the cavity of the shell 3, for supplying it with a medium under pressure and pressure relief. The housing has flanges 5.
Устройство монтируется в трубопровод, фланцы 5 служат для крепления в трубопроводе.The device is mounted in the pipeline, the flanges 5 are used for mounting in the pipeline.
При стабильной работе трубопровода оболочка 3 находится в исходном - неподдутом состоянии. При подаче давления по каналу 4 внутри оболочки 3 она раздувается, и перекрывает кольцевой просвет между корпусом 1 и каркасом 2. Регулируя подачу давления, можно уменьшить расход жидкости либо полностью перекрыть поток.With stable operation of the pipeline, the shell 3 is in its original - non-deflated condition. When applying pressure through the channel 4 inside the shell 3, it inflates and closes the annular gap between the housing 1 and the frame 2. By adjusting the pressure supply, it is possible to reduce the flow of liquid or completely shut off the flow.
Устройство применяется в качестве резервного и позволяет гарантированно перекрыть поток жидкости или газа в случае аварии и невозможности сделать этот штатными задвижками. Данное устройство не требует обслуживания в течение длительного срока - до 10 лет.The device is used as a backup and allows you to guaranteedly shut off the flow of liquid or gas in the event of an accident and the inability to make this regular valves. This device does not require maintenance for a long period - up to 10 years.
