PRESSURE ADJUSTMENT MECHANISM FOR A PRESSURE VESSEL

摘要

A pressure adjustment mechanism for a pressure vessel, a pressure adjustment knob is installed on a valve body, a lift plate linked to the pressure adjustment knob is installed on a restricted spring. The pressure adjustment knob's inside wall has a spiral guided groove in which the top portion of the lift plate is arranged. There is a clamp spring groove at the valve body's outer cylinder corresponding to the pressure adjustment knob's inside wall. The clamp spring groove has a clamp spring. This pressure adjustment system is simple, the coordination of the adjustment knob and the lift plate can continuously adjust the pressure. It particularly applies to the small pressure vessels, such as the domestic pressure cooker, steam pressure disinfecting tank and so on.
