GAS PRESSURE CONTROLLER, VALVE ASSEMBLY AND METHOD OF ASSEMBLING A GAS PRESSURE CONTROLLER

摘要

Gas pressure controller comprising a controller housing (4) with an inflow opening (2) and an outflow opening (3); a membrane (14); a valve assembly (10) placed between the inflow opening (2) and the outflow opening (3) and comprising a valve seat (11) and a closing mechanism (12) movable relative thereto for adjusting and/or closing an effective throughflow opening from the inflow opening (2) to the outflow opening (3); and a control shaft (13) which is connected to one of the closing mechanism (12) and the valve seat (11) and which connects the one of the closing mechanism and the valve seat to the membrane (14), wherein the membrane is configured to further open and/or close the valve via the control shaft (13) subject to the gas pressure on the membrane. Moreover the valve assembly (10) is releasably connectable to the controller housing (4) and the membrane (14). The application also relates to a valve assembly and a method for assembling such a gas pressure controller.
