摘要:
In a filling installation for hazardous pourable or fluid substances the substances to be packaged at the output of a production plant are divided into portions and packaged in a glove box of a sacking plant in clean room conditions. The sacking plant may be shut off from the glove box by a sealing swivelling cover. The glove box (1) is held under an overpressure and a laminar flow of pure air (43, 44) is continuously present in the glove box (1) and flows around at least one filling head (10) arranged at the output of the production plant.

摘要:
The sealing of a safety filling and emptying valve for liquid, pasty and powdery substances is disclosed. A barrel (10) to be filled or emptied is coupled to an appropriate device. A sealing ring is associated to the top part of the barrel and to the corresponding element of the device. The sealing rings (7, 8) have an approximately C-shaped profile and form two sealing surfaces (14, 15, 16, 17) that are inclined relative to each other, one (14, 17) of which is substantially horizontal and the other (15, 16) is substantially conical.
