0perating component for gas valve or pressure regulator

摘要

A basic body (1) eg. of brass or refined steel contains an ingoing gas channel (1a) for compressed gas to eg. 200 bar from a pressure gas source, eg. from a pressure gas bottle. The pressure regulating stage comprises a membrane pressure regulator, consisting of a membrane rod (19), a membrane (8), closure bolt (13'), upper pressure spring (18) and lower pressure spring (18'). A pressure gauge (38) at its central gas input is connected by an insert connection with the hollow membrane rod. The pressure gauge with the pressure display (11) and indicator (11a) is readable through a transparent arched window (37).
