  • Publication number: 20240418292
    Abstract: A timer applicable to various types of fuel gas valve and a fuel gas valve including the timer are provided. The timer includes a rotary knob, a gear-set main body, a guide plate including a guide tube, a push axle, and an elastic element. The timer is combinable with a valve body to form a fuel gas valve. With the guide plate including the guide tube in which the push axle is disposed, a push bar of the timer may push the push axle to accurately drive a valve plug assembly arranged in the valve body to open and shut down a flow passage of the valve body between an entry opening and an exit opening. This allows one single timer to be applicable to various types of valve body and a fuel gas valve including the timer enables use of fuel gas in a safe and correctly timing manner.

  • Patent number: 12085187
    Abstract: An improved gas valve including a timer includes: a valve body including a direction indicating mark; a timer arranged in an interior of the valve body; a rotary knob connected to the timer and including a protrusion, the rotary knob being provided, in a circumferentially arranged manner, with a closure region, a full opening region at one side of the closure region, and a time counting region at an opposite side of the closure region; a stop device mounted to the valve body, the stop device being subjected to an elastic effect to reciprocally move between a stop position and a passage position in such a way as to be normally set at the stop position as being acted upon by the elastic effect and located on a rotating path of the protrusion of the rotary knob.

  • Patent number: 11686405
    Abstract: A mechanical valve assembly for the control of a gas flow to a gas appliance. The mechanical valve assembly includes at least one input knob movably connected to a housing, a shaft assembly connected to at least one input knob, and a manually-operated valve located inside the housing and in between the inlet port and the outlet port. The manually-operated valve is mechanically connected to the shaft assembly, and the manually-operated valve is configured for opening and closing a gas flow between the inlet port and the outlet port.

  • Publication number: 20100243928
    Abstract: A modular gas valve arrangement including a housing that has a valve chamber having a gas inlet and a gas outlet and a valve mechanism disposed in the chamber between the inlet and the outlet to control the flow of gas. An interchangeable valve control module is mounted to the housing and has a valve actuator that moves the valve mechanism to control the position of the valve mechanism to thereby control the flow of gas. A diaphragm seal is disposed between the control module and the valve mechanism to seal the valve chamber from the control module. A diaphragm seal is connected to the valve mechanism and acts to retract the valve mechanism under pressure of gas within the valve chamber.

  • Patent number: 6755213
    Abstract: A timing switch includes a control valve, a timing device, and a flow control device. In practice, the drive shaft is pressed by the press plate at the opened state and is pressed by the elastic member at the closed state, so that the drive shaft is operated exactly to prevent from incurring leakage, thereby enhancing the safety of the timing switch of the gas stove. Thus, the timing switch can form an actual locking state when not in use, thereby providing a safety effect exactly.
