The bellows stop globle valve 50FWJ1.6P cuts off or opens the flow channel of hydrogen gas through the up and down linear movement of intervals, and its special bellows structure provides elastic support and displacement. They can be used to control the flow rate, pressure, and direction of hydrogen in power plant hydrogen systems to ensure safe and normal operation of the system. The usage method and working principle are as follows:
usage method:
Installation: Select appropriate valve specifications and types, and install them correctly according to the requirements of the pipeline system. Ensure that the valve is firmly connected to the pipeline, sealed reliably, and pay attention to the installation direction being consistent with the flow direction.
Open and close: Move the valve disc up and down by controlling the valve handle, handwheel, or other operating device. Clockwise rotation of the operating device can open the valve, while counterclockwise rotation can close the valve.
Adjust flow rate: As needed, the valve can be partially opened by gradually rotating the operating device to adjust the fluid flow rate and pressure.
working principle:
Closed state: When the valve is in the closed state, the valve disc is pushed towards the valve seat, and the sealing ring between the valve disc and the valve seat is in close contact, cutting off the flow channel of hydrogen gas and preventing hydrogen gas from passing through the valve.
Open state: When the valve needs to be opened, the valve disc is raised by operating the device. When the valve disc rises, the bellows will undergo elastic deformation, providing necessary elastic support to ensure the normal movement of the valve disc.
Cut off flow: By controlling the up and down movement of the valve disc, the flow rate of hydrogen can be adjusted. The up and down movement of the valve disc determines the degree of opening of the flow channel, thereby affecting the velocity and flow rate of fluid flow
