A timing regulator for regulating a gas flow to pass from a gas source to an outdoor gas apparatus, wherein the timing regulator comprises:
- a valve body, which has a predetermined range of operation temperature for incorporating with the outdoor gas apparatus in a safety manner, having a gas inletting end, a gas discharging end for connecting to the outdoor gas apparatus, and a gas chamber communicating between the gas inletting end and the gas discharging end, wherein the valve body further comprises a safety gas connector provided at the gas inletting end for securely and sealedly connecting to the gas source;
- wherein the valve body further comprises a gas flowing regulator for controlling the gas flow, wherein the gas flowing regulator comprises a pressurizing diaphragm movably sealing at the gas chamber and a gas valve which is operatively connected to the pressurizing diaphragm;
- wherein the gas flowing regulator further comprises a dashpot connected to the pressurizing diaphragm to adjust an amplitude movement of the pressurizing diaphragm for regulating the gas flow passing through the gas chamber;
- a gas controller comprising a gas channel having a gas outlet communicating with the gas chamber and a gas inlet defining at the gas inletting end of the valve body, and a safety device disposed in the gas channel for blocking the gas flow passing from the gas inlet to the gas outlet when a gas pressure at the gas discharging end of the valve body is higher than a safety gas pressure at the gas inletting end thereof;
- wherein the gas chamber communicates with the gas outlet of the gas controller through the gas valve, in such a manner that while increasing the pressure at the gas discharging end of the valve body, the pressurizing diaphragm is lifted to partially close the gas valve for reducing the gas flow to pass to the gas discharging end of the valve body, and while reducing the pressure gas discharging end of the valve body, the pressurizing diaphragm is sucked to partially open the gas valve for increasing the gas flow to pass to the gas discharging end of the valve body;
- and
- a timer device disposed in the valve body for selectively regulating the gas flow via a preset time frame, wherein the timer device comprises:
- a time gear assembly comprising an upper platform, a lower platform spacedly supported below the upper platform, and a gear unit supported between the upper and lower platforms to form a one-piece integral time gear assembly;
- a gas switch which is disposed within the gas chamber of the valve body and is operatively connected with the time gear assembly for controlling the gas flow through the gas chamber;
- and
- a manual time switch which is rotatably supported on the valve body and is operatively connected with the gear unit of the time gear assembly, wherein the manual time switch is arranged to actuate the gas switch through the gear unit for blocking the gas flow to pass through the gas chamber so as to shut off the valve body after the preset time frame.
