Abstract
A timing regulator, having an operation temperature of the timing regulator from −40° C. to 55° C., includes a valve body which has a gas discharging end for connecting to an outdoor gas apparatus and a safety gas connector provided at a gas inletting end for securely connecting to a gas source, a gas controller including a safety device for blocking the gas flow passing through the valve body 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, and a timer device disposed in the valve body for selectively regulating the gas flow via a preset time frame.
Claims29
A timing regulator for regulating a gas flow to pass from a gas source to an outdoor gas apparatus, wherein said timing regulator comprises:
- a valve body, which has a predetermined range of operation temperature for incorporating with said outdoor gas apparatus in a safety manner, having a gas inletting end, a gas discharging end for connecting to said outdoor gas apparatus, and a gas chamber communicating between said gas inletting end and said gas discharging end, wherein said valve body further comprises a safety gas connector provided at said gas inletting end for securely and sealedly connecting to said gas source;
- a gas controller comprising a gas channel having a gas outlet communicating with said gas chamber and a gas inlet defining at said gas inletting end of said valve body, and a safety device disposed in said gas channel for blocking said gas flow passing from said gas inlet to said gas outlet when a gas pressure at said gas discharging end of said valve body is higher than a safety gas pressure at said gas inletting end thereof;
- and
- a timer device disposed in said valve body for selectively regulating said gas flow via a preset time frame, wherein said timer device comprises:
- a time gear assembly comprising an upper platform, a lower platform spacedly supported below said upper platform, and a gear unit supported between said upper and lower platforms to form a one piece integral time gear assembly;
- a gas switch which is disposed within said gas chamber of said valve body and is operatively connected with said time gear assembly for controlling said gas flow through said gas chamber;
- and
- a manual time switch which is rotatably supported on said valve body and is operatively connected with said gear unit of said time gear assembly, wherein said manual time switch is arranged to actuate said gas switch through said gear unit for blocking said gas flow to pass through said gas chamber so as to shut off said valve body after said preset time frame.
