Coupling between fluid conveying pipelines and containers - has externally controlled pneumatic piston acting on hydraulic pressure translation piston

摘要

The pressure translation piston (4) has a smaller cross-sectional surface that the pneumatic piston (3) and mechanically couples the coupling element to the container union. Hydraulic fluid is passed by a hollow cylindrical shaft (10) from the region of the pressure translation piston into the region of a guide bush, which contains a hydraulically displaceable container coupling piston for positioning a valve plate of the coupling, as well as a displaceable valve cylinder for positioning the coupling valve (14) which blocks the through flow cross-section. The hollow cylindrical shaft is rigidly coupled to the valve cylinder and, at its end facing the pressure translation piston has a smaller cross-sectional face than at the end facing the valve opening piston (11). USE/ADVANTAGE - For containers to be filled from below,with simple handling,reliable sealing,and controllable valve function.
