Improving the Reparability of the Return Locks

During the operation of the pipeline systems, there may arise such conditions as, for example, when a pump or a compressor shuts down for emergency reasons, when there is a process reduction in pressure on some section of the pipeline, when the pipeline bursts, etc. which causes the medium to backstream. In order to eliminate such a condition, the pipeline components are used which allow the medium to move in one direction only. The direction of the stream changes for the reverse, these components close, preventing the backstreaming. Such return components include return or check valves and return locks.
