A variable pressure gas regulator comprises a housing, an inlet port for receiving a gas, an outlet port for connecting a tube to facilitate an outflow of the gas, a pressure regulator for controlling a pressure differential between the inlet port and the outlet port to maintain a stable outlet pressure of the gas, and a pressure variation means for varying the outlet pressure. The variable pressure gas regulator also comprises an excess gas flow preventing means. The pressure variation means comprises a rotatable wheel for varying the outlet pressure of the gas by controlling the pressure regulator, wherein said pressure regulator receives a pressurized gas through said inlet port and facilitates a regulated flow of the gas to the outlet port. |
