One-piece combination valve, fuel system and temperature regulating control method thereof

A fuel system, comprising a one-piece combination valve,

• wherein the one-piece combination valve comprises:
• a valve body, provided with an air guide chamber, an air inlet chamber, a first air outlet, and a second air outlet;
• an electromagnetic valve assembly, fixedly connected to the valve body;
• and
• a plug valve assembly, fixedly connected to the valve body, wherein a plug valve core of the plug valve assembly is driven under force to be rotated about a central axis of its own, so that at least one of the first air outlet and the second air outlet is/are in communication with the air guide chamber,
• wherein the plug valve core of the plug valve assembly is translated under force toward an electromagnetic valve core of the electromagnetic valve assembly and is abutted against the electromagnetic valve core, so that the air guide chamber is in communication with the air inlet chamber.

A temperature regulating control method, based on a fuel system, wherein the fuel system comprises a one-piece combination valve,

• wherein the one-piece combination valve comprises:
• a valve body, provided with an air guide chamber, an air inlet chamber, a first air outlet, and a second air outlet;
• an electromagnetic valve assembly, fixedly connected to the valve body;
• and
• a plug valve assembly, fixedly connected to the valve body, wherein a plug valve core of the plug valve assembly is driven under force to be rotated about a central axis of its own, so that at least one of the first air outlet and the second air outlet is/are in communication with the air guide chamber,
• wherein the plug valve core of the plug valve assembly is translated under force toward an electromagnetic valve core of the electromagnetic valve assembly and is abutted against the electromagnetic valve core, so that the air guide chamber is in communication with the air inlet chamber,
• the method comprising following steps:
• step 1A:
• driving the plug valve core of the plug valve assembly to be abutted against the electromagnetic valve core of the electromagnetic valve assembly, and rotating the plug valve core about a central axis of its own to be in communication with the first air outlet of the valve body, so that fluid fuel is supplied to a burner component of the fuel system;
• and
• step 2:
• initiating a fire starter of the burner component to ignite the fluid fuel, wherein a thermocouple on the burner component generates a high electrical potential to keep the electromagnetic valve core of the electromagnetic valve assembly to be in an attracted state, so that the fuel system is in a mild-flame state.
