#CMT# #/CMT# The valve has a dynamic conical seal (6) fitted outside of areas, where temperature of the areas is influenced by medium temperature. Front and rear housings (1, 2) are coaxially arranged at a pipeline axis. A seat (1a) movably fastened at the housings and the seal exhibit a rotation symmetric form at the pipeline axis. A sealing surface of the seal exhibits a conical shape. The seal is fastened to a disk (7) or represents an integral part of the disk. A rotary movement on a spindle (10) within medium-contact areas is converted into a linear movement along the pipeline axis. #CMT#USE : #/CMT# Coaxial seat valve for installation at a pipeline axis for controlling flow of a medium e.g. liquid or gas such as liquid natural gas and liquid nitrogen for an industrial application, through a pipeline. Uses include but are not limited to shock freezing, sterilization, superconduction and deburring. #CMT#ADVANTAGE : #/CMT# The dynamic seal is fitted outside of the areas at low temperatures, where temperature of the areas is influenced by the medium temperature, thus improving the sealing effect of the seat valve, and hence reducing leakages in the valve in a cost-effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic top perspective sectional view of a coaxial seat valve. 1 : Front housing 1a : Seat 2 : Rear housing 6 : Seal 7 : Disk 8 : Spindle layer 10 : Spindle 13 : Drive flange. |
