Abstract: A gas valve for a gas appliance of a gas burner system. The gas valve is connected to a gas source via a gas pipe. The gas valve is disposed with a check valve body, wherein the check valve body allows gas in the gas pipe to flow into the gas valve and prohibits the gas in the gas valve to flow into the gas pipe so the check valve body can thereby prevent the gas in the gas valve from flwoing back to the gas pipe. When gas in the gas pipe flows to to another gas appliance of the gas burner system, the gas flowing to another gas appliance does not mix with air in the gas appliance, thereby reducing the iginition time and enhancing the combustion efficiency.

Abstract: A gas appliance comprises a combustion device, an ignitor, a gas valve, a blower, a detecting device, and a control device. A control method thereof comprises: the control device is operated in a detection mode in which the control device controls the ignitor to ignite and controls the gas valve as well as the blower to provide a fixed gas flow and a fixed air flow to the combustion device. After igniting the flames, the control device determines burning states detected by the detecting device; if matching a first state, the control device controls the gas valve and the blower in correspondence to a first control data of the first natural gas; if matching the second state, the control device controls the gas valve and the blower in correspondence to a second control data of the second natural gas. In this way, the gas appliance is suitable for burning natural gas generating various heating values.

Abstract: A gas switching device incudes a valve body, a switching assembly, and a manipulating member. The valve body has an inlet portion having an inlet passage and an outlet portion having an outlet port and a receiving chamber. A wall of the receiving chamber has a side opening communicating with the inlet passage. The switching assembly includes a plug member located in the receiving chamber. The manipulating member is detachably connected to the outlet port via the connecting end connected to the plug member, and a gas passage of the connecting end communicates with an axial hole of the plug member. The manipulating member drives the plug member to turn between a first position that an outer peripheral surface of the plug member closes the side opening and a second position that the through hole communicates with the side opening.

Abstract: A kiln includes a stage, a stove, a gas supply assembly, and a combustion device wherein, the stage includes a stage body and a carrier member. The stage body has a first chamber, while the carrier member is detachably disposed at the stage body. The stove is joined to the stage body and has an entry and a second chamber. The gas supply assembly is disposed at the stage body, and part of the gas supply assembly is located in the first chamber. The combustion device is located in the second chamber.
