Locking devices PIPELINE SYSTEM DRAINAGE WATER tank floating roof

摘要

The locking device is designed to lock the entrance to the tank drain piping system for storage of oil and oil products floating roof, and a drainage pipe system extends inside the tank. The apparatus can be used for unsealing the drainage pipeline and receive a first oil in the drain line and then to the roof of the tank through the inlet water intake pipe of the drainage system. To the gate (6) on the one hand attached float (8) and, on the other hand - the rod (7). A float (8) may float in the oil or petroleum products, moving the shutter (6) to the inlet (5) up to the locking input (5) of the drainage system. The rod (7) slides when moving the shutter (6) on the guide support (9) than the deviation of the shutter is prevented (6) from the inlet (5). Using the locking device simplifies and reduces drainage system 1 ZP f ly-1-yl.
