: A large diaphragm is usually inside the saucer-shaped vessels (look at commercial-sized gas regulators outside of large buildings like motels and malls.)
: Old solid-fuel boilers often had arms that operated off the diaphragm that had the air-shutter damper to the fire chamber; they might be lost over time. As the pressure rose in the system, the damper closed to reduce fire, keeping a steady burn.
This has some sort of linkage that was attached to the exhaust but that is disconnected. I really need a piping diagram of the heating water in and around the boiler and this flying saucer and the expansion tank. The piping comes out from the bottom of the expansion tank then goes into a tee that goes up to this flying saucer then out of the saucer and then I don't understand from there.
Thanks
